Four Men Charged With Hacking 500M Yahoo Accounts

March 15, 2017

“Between two evils, I always pick the one I never tried before.” -Karim Baratov (paraphrasing Mae West)

The U.S. Justice Department today unsealed indictments against four men accused of hacking into a half-billion Yahoo email accounts. Two of the men named in the indictments worked for a unit of the Russian Federal Security Service (FSB) that serves as the FBI’s point of contact in Moscow on cybercrime cases. Here’s a look at the accused, starting with a 22-year-old who apparently did not try to hide his tracks.

According to a press release put out by the Justice Department, among those indicted was Karim Baratov (a.k.a. Kay, Karim Taloverov), a Canadian and Kazakh national who lives in Canada. Baratov is accused of being hired by the two FSB officer defendants in this case — Dmitry Dokuchaev, 33, and Igor Sushchin, 43 — to hack into the email accounts of thousands of individuals.

Karim Baratov (a.k.a. Karim Taloverov), as pictured in 2014 on his own site, mr-karim.com. The license plate on his BMW pictured here is Mr. Karim.

Reading the Justice Department’s indictment, it would seem that Baratov was perhaps the least deeply involved in this alleged conspiracy. That may turn out to be true, but he also appears to have been the least careful about hiding his activities, leaving quite a long trail of email hacking services that took about 10 minutes of searching online to trace back to him specifically.

Security professionals are fond of saying that any system is only as secure as its weakest link. It would not be at all surprising if Baratov was the weakest link in this conspiracy chain.

A look at Mr. Baratov’s Facebook and Instagram photos indicates he is heavily into high-performance sports cars. His profile picture shows two of his prized cars — a Mercedes and an Aston Martin — parked in the driveway of his single-family home in Ontario.

A simple reverse WHOIS search at domaintools.com on the name Karim Baratov turns up 81 domains registered to someone by this name in Ontario. Many of those domains include the names of big email providers like Google and Yandex, such as accounts-google[dot]net and www-yandex[dot]com.

Other domains appear to be Web sites selling email hacking services. One of those is a domain registered to Baratov’s home address in Ancaster, Ontario called infotech-team[dot]com. A cached copy of that site from archive.org shows this once was a service that offered “quality mail hacking to order, without changing the password.” The service charged roughly $60 per password.

Archive.org’s cache of infotech-team.com, an email hacking service registered to Baratov.

The proprietors of Infotech-team[dot]com advertise the ability to steal email account passwords without actually changing the victim’s password. According to the Justice Department, Baratov’s service relied on “spear phishing” emails that targeted individuals with custom content and enticed the recipient into clicking a link.

Antimail[dot]org is another domain registered to Baratov that was active between 2013 and 2015. It advertises “quality-mail hacking to order!”:

Another email hacking business registered to Baratov is xssmail[dot]com, which also has for several years advertised the ability to break into email accounts of virtually all of the major Webmail providers. XSS is short for “cross-site-scripting.” XSS attacks rely on vulnerabilities in Web sites that don’t properly parse data submitted by visitors in things like search forms or anyplace one might enter data on a Web site.

In the context of phishing links, the user clicks the link and is actually taken to the domain he or she thinks she is visiting (e.g., yahoo.com) but the vulnerability allows the attacker to inject malicious code into the page that the victim is visiting.

This can include fake login prompts that send any data the victim submits directly to the attacker. Alternatively, it could allow the attacker to steal “cookies,” text files that many sites place on visitors’ computers to validate whether they have visited the site previously, as well as if they have authenticated to the site already.

Archive.org’s cache of xssmail.com

Perhaps instead of or in addition to using XSS attacks in targeted phishing emails, Baratov also knew about or had access to other cookie-stealing exploits collected by another accused in today’s indictments: Russian national Alexsey Alexseyevich Belan.

According to government investigators, Belan has been on the FBI’s Cyber Most Wanted list since 2013 after breaking into and stealing credit card data from a number of e-commerce companies. In June 2013, Belan was arrested in a European country on request from the United States, but the FBI says he was able to escape to Russia before he could be extradited to the U.S. Continue reading →

Adobe, Microsoft Push Critical Security Fixes

March 14, 2017

Adobe and Microsoft each pushed out security updates for their products today. Adobe plugged at least seven security holes in its Flash Player software. Microsoft, which delayed last month’s Patch Tuesday until today, issued an unusually large number of update bundles (18) to fix dozens of flaws in Windows and associated software.

brokenwindows Microsoft’s patch to fix at least five critical bugs in the Windows file-sharing service is bound to make a great deal of companies nervous before they get around to deploying this week’s patches. Most organizations block internal file-sharing networks from talking directly to their Internet-facing networks, but these flaws could be exploited by a malicious computer worm to spread very quickly once inside an organization with a great many unpatched Windows systems.

Another critical patch (MS17-013) covers a slew of dangerous vulnerabilities in the way Windows handles certain image files. Malware or miscreants could exploit the flaws to foist malicious software without any action on the part the user, aside from perhaps just browsing to a hacked or booby-trapped Web site.

If Your iPhone is Stolen, These Guys May Try to iPhish You

March 14, 2017

58 Comments

KrebsOnSecurity recently featured the story of a Brazilian man who was peppered with phishing attacks trying to steal his Apple iCloud username and password after his wife’s phone was stolen in a brazen daylight mugging. Today, we’ll take an insider’s look at an Apple iCloud phishing gang that appears to work quite closely with organized crime rings — within the United States and beyond — to remotely unlock and erase stolen Apple devices.

Victims of iPhone theft can use the Find My iPhone feature to remotely locate, lock or erase their iPhone — just by visiting Apple’s site and entering their iCloud username and password. Likewise, an iPhone thief can use those iCloud credentials to remotely unlock the victim’s stolen iPhone, wipe the device, and resell it. As a result, iPhone thieves often subcontract the theft of those credentials to third-party iCloud phishing services. This story is about one of those services.

The iCloud account phishing text that John’s friend received months after losing a family iPhone.

Recently, I heard from a security professional whose close friend received a targeted attempt to phish his Apple iCloud credentials. The phishing attack came several months after the friend’s child lost his phone at a public park in Virginia. The phish arrived via text message and claimed to have been sent from Apple. It said the device tied to his son’s phone number had been found, and that its precise location could be seen for the next 24 hours by clicking a link embedded in the text message.

That security professional source — referred to as “John” for simplicity’s sake — declined to be named or credited in this story because some of the actions he took to gain the knowledge presented here may run afoul of U.S. computer fraud and abuse laws.

John said his friend clicked on the link in the text message he received about his son’s missing phone and was presented with a fake iCloud login page: appleid-applemx[dot]us. A lookup on that domain indicates it is hosted on a server in Russia that is or was shared by at least 140 other domains — mostly other apparent iCloud phishing sites — such as accounticloud[dot]site; apple-appleid[dot]store; apple-devicefound[dot]org; and so on (a full list of the domains at that server is available here).

While the phishing server may be hosted in Russia, its core users appear to be in a completely different part of the world. Examining the server more closely, John noticed that it was (mis)configured in a way that leaked data about various Internet addresses that were seen recently accessing the server, as well as the names of specific directories on the server that were being accessed.

After monitoring that logging information for some time, my source discovered there were five Internet addresses that communicated with the server multiple times a day, and that those address corresponded to devices located in Argentina, Colombia, Ecuador and Mexico.

He also found a file openly accessible on the Russian server which indicated that an application running on the server was constantly sending requests to imei24.com and imeidata.net — services that allow anyone to look up information about a mobile device by entering its unique International Mobile Equipment Identity (IMEI) number. These services return a variety of information, including the make and model of the phone, whether Find My iPhone is enabled for the device, and whether the device has been locked or reported stolen.

John said that as he was conducting additional reconnaissance of the Russian server, he tried to access “index.php” — which commonly takes one to a site’s home page — when his browser was redirected to “login.php” instead. The resulting page, pictured below, is a login page for an application called “iServer.” The login page displays a custom version of Apple’s trademarked logo as part of a pirate’s skull and crossbones motif, set against a background of bleeding orange flames.

The login page for an Apple iCloud credential phishing operation apparently used to unlock and remotely wipe stolen iPhones.

John told me that in addition to serving up that login page, the server also returned the HTML contents of the “index.php” he originally requested from the server. When he saved the contents of index.php to his computer and viewed it as a text file, he noticed it inexplicably included a list of some 137 user names, email addresses and expiration dates for various users who’d apparently paid a monthly fee to access the iCloud phishing service.

“These appear to be ‘resellers’ or people that have access to the crimeware server,” my source said of the user information listed in the server’s “index.php” file.

John told KrebsOnSecurity that with very little effort he was able to guess the password of at least two other users listed in that file. After John logged into the iCloud phishing service with those credentials, the service informed him that the account he was using was expired. John was then prompted to pay for at least one more month subscription access to the server to continue.

Playing along, John said he clicked the “OK” button indicating he wished to renew his subscription, and was taken to a shopping cart hosted on the domain hostingyaa[dot]com. That payment form in turn was accepting PayPal payments for an account tied to an entity called HostingYaa LLC; viewing the HTML source on that payment page revealed the PayPal account was tied to the email address “admin@hostingyaa[dot]com.”

According to the file coughed up by the Russian server, the first username in that user list — demoniox12 — is tied to an email address admin@lanzadorx.net and to a zero-dollar subscription to the phishing service. This strongly indicates the user in question is an administrator of this phishing service.

A review of Lanzadorx[dot]net indicates that it is a phishing-as-a-service offering that advertises the ability to launch targeted phishing attacks at a variety of free online services, including accounts at Apple, Hotmail, Gmail and Yahoo, among others.

A reverse WHOIS lookup ordered from Domaintools.com shows that the admin@lanzadorx.net email is linked to the registration data for exactly two domains — hostingyaa[dot]info and lanzadorx[dot]net [full disclosure: Domaintools is currently one of several advertisers on KrebsOnSecurity].

Hostingyaa[dot]info is registered to a Dario Dorrego, one of the other zero-dollar accounts included near the top of the list of users that are authorized to access the iCloud phishing service. The site says Dorrego’s account corresponds to the email address dario@hostingyaa[dot]com. That name Dario Dorrego also appears in the site registration records for 31 other Web site domains, all of which are listed here.

John said he was able to guess the passwords for at least six other accounts on the iCloud phishing service, including one particularly interesting user and possible reseller of the service who picked the username “Jonatan.” Below is a look at the home screen for Jonatan’s account on this iCloud phishing service. We can see the system indicates Jonatan was able to obtain at least 65 “hacked IDs” through this service, and that he pays USD $80 per month for access to it.

Dahua, Hikvision IoT Devices Under Siege

March 10, 2017

32 Comments

Dahua, the world’s second-largest maker of “Internet of Things” devices like security cameras and digital video recorders (DVRs), has shipped a software update that closes a gaping security hole in a broad swath of its products. The vulnerability allows anyone to bypass the login process for these devices and gain remote, direct control over vulnerable systems. Adding urgency to the situation, there is now code available online that allows anyone to exploit this bug and commandeer a large number of IoT devices.

dahua On March 5, a security researcher named Bashis posted to the Full Disclosure security mailing list exploit code for an embarrassingly simple flaw in the way many Dahua security cameras and DVRs handle authentication. These devices are designed to be controlled by a local Web server that is accessible via a Web browser.

That server requires the user to enter a username and password, but Bashis found he could force all affected devices to cough up their usernames and a simple hashed value of the password. Armed with this information, he could effectively “pass the hash” and the corresponding username right back to the Web server and be admitted access to the device settings page. From there, he could add users and install or modify the device’s software. From Full Disclosure:

“This is so simple as:
1. Remotely download the full user database with all credentials and permissions
2. Choose whatever admin user, copy the login names and password hashes
3. Use them as source to remotely login to the Dahua devices

“This is like a damn Hollywood hack, click on one button and you are in…”

Bashis said he was so appalled at the discovery that he labeled it an apparent “backdoor” — an undocumented means of accessing an electronic device that often only the vendor knows about. Enraged, Bashis decided to publish his exploit code without first notifying Dahua. Later, Bashis said he changed his mind after being contacted by the company and agreed to remove his code from the online posting.

Unfortunately, that ship may have already sailed. Bashis’s exploit code already has been copied in several other places online as of this publication.

Asked why he took down his exploit code, Bashis said in an interview with KrebsOnSecurity that “The hack is too simple, way too simple, and now I want Dahua’s users to get patched firmware’s before they will be victims to some botnet.”

In an advisory published March 6, Dahua said it has identified nearly a dozen of its products that are vulnerable, and that further review may reveal additional models also have this flaw. The company is urging users to download and install the newest firmware updates as soon as possible. Here are the models known to be affected so far:

DH-IPC-HDW23A0RN-ZS
DH-IPC-HDBW23A0RN-ZS
DH-IPC-HDBW13A0SN
DH-IPC-HDW13A0SN
DH-IPC-HFW13A0SN-W
DH-IPC-HDBW13A0SN
DH-IPC-HDW13A0SN
DH-IPC-HFW13A0SN-W
DHI-HCVR51A04HE-S3
DHI-HCVR51A08HE-S3
DHI-HCVR58A32S-S2

It’s not clear exactly how many devices worldwide may be vulnerable. Bashis says that’s a difficult question to answer, but that he “wouldn’t be surprised if 95 percent of Dahua’s product line has the same problem,” he said. “And also possible their OEM clones.”

Dahua has not yet responded to my questions or request for comment. I’ll update this post if things change on that front.

This is the second time in a week that a major Chinese IoT firm has urgently warned its customers to update the firmware on their devices. For weeks, experts have been warning that there are signs of attackers exploiting an unknown backdoor or equally serious vulnerability in cameras and DVR devices made by IoT giant Hikvision.

WikiLeaks: We’ll Work With Software Makers on Zero-Days

March 9, 2017

67 Comments

When WikiLeaks on Tuesday dumped thousands of files documenting hacking tools used by the U.S. Central Intelligence Agency, many feared WikiLeaks would soon publish a trove of so-called “zero days,” the actual computer code that the CIA uses to exploit previously unknown flaws in a range of software and hardware products used by consumers and businesses. But on Thursday, WikiLeaks editor-in-chief Julian Assange promised that his organization would work with hardware and software vendors to fix the security weaknesses prior to releasing additional details about the flaws.

“After considering what we think is the best way to proceed, and hearing these calls from some of the manufacturers, we have decided to work with them to give them exclusive access to additional technical details we have, so that fixes can be developed and pushed out,” Assange said in a press conference put on by his organization. “Once this material is effectively disarmed by us, we will publish additional details about what has been occurring.”

Source: Twitter

So-called “zero-day” flaws refer to vulnerabilities in hardware or software products that vendors first learn about when those flaws are already under active attack (i.e., the vendor has “zero days” to fix the vulnerability before it begins affecting its customers and users). Zero-day flaws are highly prized by cybercriminals and nation states alike because they potentially allow attackers to stealthily bypass a target’s digital defenses.

It’s unclear if WikiLeak’s decision to work with software makers on zero-days was impacted by a poll the organization took via its Twitter page over the past few days. The tweet read: “Tech companies are saying they need more details of CIA attack techniques to fix them faster. Should WikiLeaks work directly with them?”

So far, just over 38,000 people have responded, with a majority (57 percent) saying “Yes, make people safe,” while only 36 percent selected “no, they’re part of the problem.”

Assange didn’t offer additional details about the proposed information-sharing process he described, such as whether WikiLeaks would seek to work with affected vendors individually or if it might perhaps rely on a trusted third-party or third-parties to assist in that process. Continue reading →

WikiLeaks Dumps Docs on CIA’s Hacking Tools

March 8, 2017

128 Comments

WikiLeaks on Tuesday dropped one of its most explosive word bombs ever: A secret trove of documents apparently stolen from the U.S. Central Intelligence Agency (CIA) detailing methods of hacking everything from smart phones and TVs to compromising Internet routers and computers. KrebsOnSecurity is still digesting much of this fascinating data cache, but here are some first impressions based on what I’ve seen so far.

First, to quickly recap what happened: In a post on its site, WikiLeaks said the release — dubbed “Vault 7” — was the largest-ever publication of confidential documents on the agency. WikiLeaks is promising a series of these document caches; this first one includes more than 8,700 files allegedly taken from a high-security network inside CIA’s Center for Cyber Intelligence in Langley, Va.

The home page for the CIA’s “Weeping Angel” project, which sought to exploit flaws that could turn certain 2013-model Samsung “smart” TVs into remote listening posts.

“Recently, the CIA lost control of the majority of its hacking arsenal including malware, viruses, trojans, weaponized ‘zero day’ exploits, malware remote control systems and associated documentation,” WikiLeaks wrote. “This extraordinary collection, which amounts to more than several hundred million lines of code, gives its possessor the entire hacking capacity of the CIA. The archive appears to have been circulated among former U.S. government hackers and contractors in an unauthorized manner, one of whom has provided WikiLeaks with portions of the archive.”

Wikileaks said it was calling attention to the CIA’s global covert hacking program, its malware arsenal and dozens of weaponized exploits against “a wide range of U.S. and European company products, includ[ing] Apple’s iPhone, Google’s Android and Microsoft’s Windows and even Samsung TVs, which are turned into covert microphones.”

The documents for the most part don’t appear to include the computer code needed to exploit previously unknown flaws in these products, although WikiLeaks says those exploits may show up in a future dump. This collection is probably best thought of as an internal corporate wiki used by multiple CIA researchers who methodically found and documented weaknesses in a variety of popular commercial and consumer electronics.

For example, the data dump lists a number of exploit “modules” available to compromise various models of consumer routers made by companies like Linksys, Microtik and Zyxel, to name a few. CIA researchers also collated several pages worth of probing and testing weaknesses in business-class devices from Cisco, whose powerful routers carry a decent portion of the Internet’s traffic on any given day. Craig Dods, a researcher with Cisco’s rival Juniper, delves into greater detail on the Cisco bugs for anyone interested (Dods says he found no exploits for Juniper products in the cache, yet). Meanwhile, Cisco has published its own blog post on the matter.

WHILE MY SMART TV GENTLY WEEPS

Some of the exploits discussed in these leaked CIA documents appear to reference full-on, remote access vulnerabilities. However, a great many of the documents I’ve looked at seem to refer to attack concepts or half-finished exploits that may be limited by very specific requirements — such as physical access to the targeted device.

The “Weeping Angel” project’s page from 2014 is a prime example: It discusses ways to turn certain 2013-model Samsung “smart TVs” into remote listening devices; methods for disabling the LED lights that indicate the TV is on; and suggestions for fixing a problem with the exploit in which the WiFi interface on the TV is disabled when the exploit is run.

ToDo / Future Work:
Build a console cable

Turn on or leave WiFi turned on in Fake-Off mode

Parse unencrypted audio collection
Clean-up the file format of saved audio. Add encryption??

According to the documentation, Weeping Angel worked as long as the target hadn’t upgraded the firmware on the Samsung TVs. It also said the firmware upgrade eliminated the “current installation method,” which apparently required the insertion of a booby-trapped USB device into the TV.

Don’t get me wrong: This is a serious leak of fairly sensitive information. And I sincerely hope Wikileaks decides to work with researchers and vendors to coordinate the patching of flaws leveraged by the as-yet unreleased exploit code archive that apparently accompanies this documentation from the CIA.

But in reading the media coverage of this leak, one might be led to believe that even if you are among the small minority of Americans who have chosen to migrate more of their communications to privacy-enhancing technologies like Signal or WhatsApp, it’s all futility because the CIA can break it anyway.

Perhaps a future cache of documents from this CIA division will change things on this front, but an admittedly cursory examination of these documents indicates that the CIA’s methods for weakening the privacy of these tools all seem to require attackers to first succeed in deeply subverting the security of the mobile device — either through a remote-access vulnerability in the underlying operating system or via physical access to the target’s phone.

As Bloomberg’s tech op-ed writer Leonid Bershidsky notes, the documentation released here shows that these attacks are “not about mass surveillance — something that should bother the vast majority of internet users — but about monitoring specific targets.”

By way of example, Bershidsky points to a tweet yesterday from Open Whisper Systems (the makers of the Signal private messaging app) which observes that, “The CIA/Wikileaks story today is about getting malware onto phones, none of the exploits are in Signal or break Signal Protocol encryption.”

The company went on to say that because more online services are now using end-to-end encryption to prevent prying eyes from reading communications that are intercepted in-transit, intelligence agencies are being pushed “from undetectable mass surveillance to expensive, high-risk, targeted attacks.”

Payments Giant Verifone Investigating Breach

March 7, 2017

81 Comments

Credit and debit card payments giant Verifone [NYSE: PAY] is investigating a breach of its internal computer networks that appears to have impacted a number of companies running its point-of-sale solutions, according to sources. Verifone says the extent of the breach was limited to its corporate network and that its payment services network was not impacted.

San Jose, Calif.-based Verifone is the largest maker of credit card terminals used in the United States. It sells point-of-sale terminals and services to support the swiping and processing of credit and debit card payments at a variety of businesses, including retailers, taxis, and fuel stations.

On Jan. 23, 2017, Verifone sent an “urgent” email to all company staff and contractors, warning they had 24 hours to change all company passwords.

“We are currently investigating an IT control matter in the Verifone environment,” reads an email memo penned by Steve Horan, Verifone Inc.’s senior vice president and chief information officer. “As a precaution, we are taking immediate steps to improve our controls.”

An internal memo sent Jan. 23, 2017 by Verifone’s chief information officer to all staff and contractors, telling them to change their passwords. The memo also states that Verifone employees would no longer be able to install software at will, apparently something everyone at the company could do prior to this notice.

The internal Verifone memo — a copy of which was obtained by KrebsOnSecurity and is pictured above — also informed employees they would no longer be allowed to install software of any kind on company computers and laptops.

Asked about the breach reports, a Verifone spokesman said the company saw evidence in January 2017 of an intrusion in a “limited portion” of its internal network, but that the breach never impacted its payment services network.

An ad tied to Verifone’s petroleum services point-of-sale offerings.

“In January 2017, Verifone’s information security team saw evidence of a limited cyber intrusion into our corporate network,” Verifone spokesman Andy Payment said. “Our payment services network was not impacted. We immediately began work to determine the type of information targeted and executed appropriate measures in response. We believe today that due to our immediate response, the potential for misuse of information is limited.”

Verifone’s Mr. Payment declined to answer additional questions about the breach, such as how Verifone learned about it and whether the company was initially notified by an outside party. But a source with knowledge of the matter told KrebsOnSecurity.com that the employee alert Verifone sent out on Jan, 23, 2017 was in response to a notification that Verifone received from the credit card companies Visa and Mastercard just days earlier in January.

A spokesperson for Visa declined to comment for this story. MasterCard officials did not respond to requests for comment.

According to my source, the intrusion impacted at least one corner of Verifone’s business: A customer support unit based in Clearwater, Fla. that provides comprehensive payment solutions specifically to gas and petrol stations throughout the United States — including, pay-at-the-pump credit card processing; physical cash registers inside the fuel station store; customer loyalty programs; and remote technical support.

The source said his employer shared with the card brands evidence that a Russian hacking group known for targeting payment providers and hospitality firms had compromised at least a portion of Verifone’s internal network.

The source says Visa and MasterCard were notified that the intruders appeared to have been inside of Verifone’s network since mid-2016. The source noted there is ample evidence the attackers used some of the same toolsets and infrastructure as the cybercrime gang that last year is thought to have hacked into Oracle’s MICROS division, a unit of Oracle that provides point-of-sale solutions to hundreds of thousands of retailers and hospitality firms.

Founded in Hawaii, U.S. in 1981, Verifone now operates in more than 150 countries worldwide and employ nearly 5,000 people globally.

Update, 1:17 p.m. ET: Verifone circled back post-publication with the following update to their statement: “According to the forensic information to-date, the cyber attempt was limited to controllers at approximately two dozen gas stations, and occurred over a short time frame. We believe that no other merchants were targeted and the integrity of our networks and merchants’ payment terminals remain secure and fully operational.”

Sources told KrebsOnSecurity that Verifone commissioned an investigation of the breach from Foregenix Ltd., a digital forensics firm based in the United Kingdom that lists Verifone as a “strategic partner.” Foregenix declined to comment for this story.

Ransomware for Dummies: Anyone Can Do It

March 1, 2017

88 Comments

Among today’s fastest-growing cybercrime epidemics is “ransomware,” malicious software that encrypts your computer files, photos, music and documents and then demands payment in Bitcoin to recover access to the files. A big reason for the steep increase in ransomware attacks in recent years comes from the proliferation of point-and-click tools sold in the cybercrime underground that make it stupid simple for anyone to begin extorting others for money.

Recently, I came across an extremely slick and professionally produced video advertisement promoting the features and usability of “Philadelphia,” a ransomware-as-a-service crimeware package that is sold for roughly $400 to would-be cybercriminals who dream of carving out their own ransomware empires.

This stunning advertisement does a thorough job of showcasing Philadelphia’s many features, including the ability to generate PDF reports and charts of victims “to track your malware campaigns” as well as the ability to plot victims around the world using Google Maps.

“Everything just works,” claim the proprietors of Philadelphia. “Get your lifetime copy. One payment. Free updates. No monthly fees.”

One interesting feature of this ransomware package is the ability to grant what the program’s architects call “mercy.” This refers to the desperate and heartbreaking pleas that ransomware purveyors often hear from impecunious victims whose infections have jeopardized some priceless and irreplaceable data — such as photos of long lost loved ones.

I’ll revisit the authors of this ransomware package in a future post. For now, just check out their ad. It’s fairly chilling.

More on Bluetooth Ingenico Overlay Skimmers

February 26, 2017

This blog has featured several stories about “overlay” card and PIN skimmers made to be placed atop Ingenico-brand card readers at store self-checkout lanes. I’m revisiting the topic again because a security technician at a U.S.-based retailer recently shared a few photos of several of these devices pulled from compromised card terminals, and the images and his story offer a fair bit more detail than in previous articles.

An “overlay” skimming device (right) that was found attached to a card reader at a retail establishment.

The device featured here is a Bluetooth-based skimmer; it is designed to steal both the card data when a customer swipes and to record the victim’s PIN using a PIN pad overlay.

The Bluetooth component of the skimmer allows the thieves to retrieve stolen data wirelessly via virtually any Bluetooth enabled device — just by being in proximity to the compromised card terminal (~30 meters).

If we look on the backside of this skimmer, we can see the electronics needed to intercept the PIN. The source who shared these pictures said an employee thought the PIN pad buttons were a little too difficult to press down, and soon discovered this plastic overlay and others just like it on two more self-checkout terminals.

iPhone Robbers Try to iPhish Victims

February 24, 2017

38 Comments

In another strange tale from the kinetic-attack-meets-cyberattack department, earlier this week I heard from a loyal reader in Brazil whose wife was recently mugged by three robbers who nabbed her iPhone. Not long after the husband texted the stolen phone — offering to buy back the locked device — he soon began receiving text messages stating the phone had been found. All he had to do to begin the process of retrieving the device was click the texted link and log in to the phishing page mimicking Apple’s site.

applephish

Edu Rabin is a resident of Porto Alegre, the capital and largest city of the Brazilian state of Rio Grande do Sul in southern Brazil. Rabin said three thugs robbed his wife last Saturday in broad daylight. Thankfully, she was unharmed and all they wanted was her iPhone 5s.

Rabin said he then tried to locate the device using the “Find my iPhone” app.

“It was already in a nearby city, where the crime rates are even higher than mine,” Rabin said.

He said he then used his phone to send the robbers a message offering to buy back his wife’s phone.

“I’d sent a message with my phone number saying, ‘Dear mister robber, since you can’t really use the phone, I’m preparing to rebuy it from you. All my best!’ This happened on Saturday. On Sunday, I’d checked again the search app and the phone was still offline and at same place.”

But the following day he began receiving text messages stating that his phone had been recovered.

“On Monday, I’d started to receive SMS messages saying that my iphone had been found and a URL to reach it,” Rabin said. Here’s a screenshot of one of those texts:

The link led to a page that looks exactly like the Brazilian version of Apple’s sign-in page, but which is hosted on a site that allows free Web hosting.
