When Identity Thieves Hack Your Accountant

April 11, 2018

The Internal Revenue Service has been urging tax preparation firms to step up their cybersecurity efforts this year, warning that identity thieves and hackers increasingly are targeting certified public accountants (CPAs) in a bid to siphon oodles of sensitive personal and financial data on taxpayers. This is the story of a CPA in New Jersey whose compromise by malware led to identity theft and phony tax refund requests filed on behalf of his clients.

Last month, KrebsOnSecurity was alerted by security expert Alex Holden of Hold Security about a malware gang that appears to have focused on CPAs. The crooks in this case were using a Web-based keylogger that recorded every keystroke typed on the target’s machine, and periodically uploaded screenshots of whatever was being displayed on the victim’s computer screen at the time.

If you’ve never seen one of these keyloggers in action, viewing their output can be a bit unnerving. This particular malware is not terribly sophisticated, but nevertheless is quite effective. It not only grabs any data the victim submits into Web-based forms, but also captures any typing — including backspaces and typos as we can see in the screenshot below.

The malware records everything its victims type (including backspaces and typos), and frequently takes snapshots of the victim’s computer screen.

Whoever was running this scheme had all victim information uploaded to a site that was protected from data scraping by search engines, but the site itself did not require any form of authentication to view data harvested from victim PCs. Rather, the stolen information was indexed by victim and ordered by day, meaning anyone who knew the right URL could view each day’s keylogging record as one long image file.

Those records suggest that this particular CPA — “John,” a New Jersey professional whose real name will be left out of this story — likely had his computer compromised sometime in mid-March 2018 (at least, this is as far back as the keylogging records go for John).

It’s also not clear exactly which method the thieves used to get malware on John’s machine. Screenshots for John’s account suggest he routinely ignored messages from Microsoft and other third party Windows programs about the need to apply critical security updates.

Messages like this one — about critical security updates available for QuickBooks — went largely ignored, according to multiple screenshots from John’s computer.

More likely, however, John’s computer was compromised by someone who sent him a booby-trapped email attachment or link. When one considers just how frequently CPAs must need to open Microsoft Office and other files submitted by clients and potential clients via email, it’s not hard to imagine how simple it might be for hackers to target and successfully compromise your average CPA.

The keylogging malware itself appears to have been sold (or perhaps directly deployed) by a cybercriminal who uses the nickname ja_far. This individual markets a $50 keylogger product alongside a malware “crypting” service that guarantees his malware will be undetected by most antivirus products for a given number of days after it is used against a victim.

Ja_far’s sales threads for the keylogger used to steal tax and financial data from hundreds of John’s clients.

It seems likely that ja_far’s keylogger was the source of this data because at one point — early in the morning John’s time — the attacker appears to have accidentally pasted ja_far’s jabber instant messenger address into the victim’s screen instead of his own. In all likelihood, John’s assailant was seeking additional crypting services to ensure the keylogger remained undetected on John’s PC. A couple of minutes later, the intruder downloaded a file to John’s PC from file-sharing site sendspace.com.

The attacker apparently messing around on John’s computer while John was not sitting in front of the keyboard.

What I found remarkable about John’s situation was despite receiving notice after notice that the IRS had rejected many of his clients’ tax returns because those returns had already been filed by fraudsters, for at least two weeks John does not appear to have suspected that his compromised computer was likely the source of said fraud inflicted on his clients (or if he did, he didn’t share this notion with any of his friends or family via email).

Instead, John composed and distributed to his clients a form letter about their rejected returns, and another letter that clients could use to alert the IRS and New Jersey tax authorities of suspected identity fraud. Continue reading

Adobe, Microsoft Push Critical Security Fixes

April 10, 2018

Adobe and Microsoft each released critical fixes for their products today, a.k.a “Patch Tuesday,” the second Tuesday of every month. Adobe updated its Flash Player program to resolve a half dozen critical security holes. Microsoft issued updates to correct at least 65 security vulnerabilities in Windows and associated software.

The Microsoft updates impact many core Windows components, including the built-in browsers Internet Explorer and Edge, as well as Office, the Microsoft Malware Protection Engine, Microsoft Visual Studio and Microsoft Azure.

The Malware Protection Engine flaw is one that was publicly disclosed earlier this month, and one for which Redmond issued an out-of-band (outside of Patch Tuesday) update one week ago.

That flaw, discovered and reported by Google’s Project Zero program, is reportedly quite easy to exploit and impacts the malware scanning capabilities for a variety of Microsoft anti-malware products, including Windows Defender, Microsoft Endpoint Protection and Microsoft Security Essentials.

Microsoft really wants users to install these updates as quickly as possible, but it might not be the worst idea to wait a few days before doing so: Quite often, problems with patches that may cause systems to end up in an endless reboot loop are reported and resolved with subsequent updates within a few days after their release. However, depending on which version of Windows you’re using it may be difficult to put off installing these patches.

Microsoft says by default, Windows 10 receives updates automatically, “and for customers running previous versions, we recommend they turn on automatic updates as a best practice.” Microsoft doesn’t make it easy for Windows 10 users to change this setting, but it is possible. For all other Windows OS users, if you’d rather be alerted to new updates when they’re available so you can choose when to install them, there’s a setting for that in Windows Update. In any case, don’t put off installing these updates too long. Continue reading

Don’t Give Away Historic Details About Yourself

April 9, 2018

Social media sites are littered with seemingly innocuous little quizzes, games and surveys urging people to reminisce about specific topics, such as “What was your first job,” or “What was your first car?” The problem with participating in these informal surveys is that in doing so you may be inadvertently giving away the answers to “secret questions” that can be used to unlock access to a host of your online identities and accounts.

I’m willing to bet that a good percentage of regular readers here would never respond — honestly or otherwise — to such questionnaires (except perhaps to chide others for responding). But I thought it was worth mentioning because certain social networks — particularly Facebook — seem positively overrun with these data-harvesting schemes. What’s more, I’m constantly asking friends and family members to stop participating in these quizzes and to stop urging their contacts to do the same.

On the surface, these simple questions may be little more than an attempt at online engagement by otherwise well-meaning companies and individuals. Nevertheless, your answers to these questions may live in perpetuity online, giving identity thieves and scammers ample ammunition to start gaining backdoor access to your various online accounts.

Consider, for example, the following quiz posted to Facebook by San Benito Tire Pros, a tire and auto repair shop in California. It asks Facebook users, “What car did you learn to drive stick shift on?”

I hope this is painfully obvious, but for many people the answer will be the same as to the question, “What was the make and model of your first car?”, which is one of several “secret questions” most commonly used by banks and other companies to let customers reset their passwords or gain access to the account without knowing the password.

This simple one-question quiz has been shared more than 250 times on Facebook since it was posted a week ago. Thousands of Facebook users responded in earnest, and in so doing linked their profile to the answer.

Probably the most well-known and common secret question, “what was the name of your first pet,” comes up in a number of Facebook quizzes that, incredibly, thousands of people answer willingly and (apparently) truthfully. When I saw this one I was reminded of this hilarious 2007 Daily Show interview wherein Jon Stewart has Microsoft co-founder Bill Gates on and tries to slyly ask him the name of his first pet.

Almost 5,000 Facebook users answered this common password reset secret question.

Secret Service Warns of Chip Card Scheme

April 5, 2018

The U.S. Secret Service is warning financial institutions about a new scam involving the temporary theft of chip-based debit cards issued to large corporations. In this scheme, the fraudsters intercept new debit cards in the mail and replace the chips on the cards with chips from old cards. When the unsuspecting business receives and activates the modified card, thieves can start draining funds from the account.

Signs of a card with an old or invalid chip include heat damage around the chip or on the card, or a small hole in the plastic used to pry the chip off the card. Image: U.S. Secret Service.

According to an alert sent to banks late last month, the entire scheme goes as follows:

1. Criminals intercept mail sent from a financial institution to large corporations that contain payment cards, targeting debit payment cards with access to large amount of funds.

2. The crooks remove the chip from the debit payment card using a heat source that warms the glue.

3. Criminals replace the chip with an old or invalid chip and repackage the payment card for delivery.

4. Criminals place the stolen chip into an old payment card.

5. The corporation receives the debit payment card without realizing the chip has been replaced.

6. The corporate office activates the debit payment card; however, their payment card is inoperable thanks to the old chip.

7. Criminals use the payment card with the stolen chip for their personal gain once the corporate office activates the card. Continue reading

Dot-cm Typosquatting Sites Visited 12M Times So Far in 2018

April 4, 2018

A story published here last week warned readers about a vast network of potentially malicious Web sites ending in “.cm” that mimic some of the world’s most popular Internet destinations (e.g. espn[dot]cm, aol[dot]cm and itunes[dot].cm) in a bid to bombard visitors with fake security alerts that can lock up one’s computer. If that piece lacked one key detail it was insight into just how many people were mistyping .com and ending up at one of these so-called “typosquatting” domains.

On March 30, an eagle-eyed reader noted that four years of access logs for the entire network of more than 1,000 dot-cm typosquatting domains were available for download directly from the typosquatting network’s own hosting provider. The logs — which include detailed records of how many people visited the sites over the past three years and from where — were deleted shortly after that comment was posted here, but not before KrebsOnSecurity managed to grab a copy of the entire archive for analysis.

The geographic distribution of 25,000 randomly selected Internet addresses (IP addresses) in the logs seen accessing the dot-cm typosquatting domains in February 2018. Batchgeo, the service used to produce this graphic, limits free lookups to 25,000, but the above image is likely still representative of the overall geographic distribution. Perhaps unsurprisingly, the largest share of traffic is coming from the United States.

Matthew Chambers, a security expert with whom this author worked on the original dot-cm typosquatting story published last week, analyzed the access logs from just the past three months and found the sites were visited approximately 12 million times during the first quarter of 2018.

Chambers said he combed through the logs and weeded out hits from Internet addresses that appeared to be bots or search engine scrapers. Here’s Chambers’ analysis of the 2018 access log data:

January 2018; 3,732,488 visitors
February 2018: 3,799,109 visitors
Mar 2018: 4,275,998 visitors

Total Jan-Mar 2018 is 11.8 million

Those figures suggest that the total number of visits to these typosquatting sites in the first quarter of 2018 was approximately 12 million, or almost 50 million hits per year. Certainly, not everyone visiting these sites will have the experience that Chambers’ users reported (being bombarded with misleading malware alerts and redirected to scammy and spammy Web sites), but it seems clear this network could make its operators a pretty penny regardless of the content that ends up getting served through it.

Panerabread.com Leaks Millions of Customer Records

April 2, 2018

Panerabread.com, the Web site for the American chain of bakery-cafe fast casual restaurants by the same name, leaked millions of customer records — including names, email and physical addresses, birthdays and the last four digits of the customer’s credit card number — for at least eight months before it was yanked offline earlier today, KrebsOnSecurity has learned.

The data available in plain text from Panera’s site appeared to include records for any customer who has signed up for an account to order food online via panerabread.com. The St. Louis-based company, which has more than 2,100 retail locations in the United States and Canada, allows customers to order food online for pickup in stores or for delivery.

Redacted records from Panera’s site, which let anyone search by a variety of customer attributes, including phone number, email address, physical address or loyalty account number. In this example, the phone number was a main line at an office building where many different employees apparently registered to order food online.

KrebsOnSecurity learned about the breach earlier today after being contacted by security researcher Dylan Houlihan, who said he initially notified Panera about customer data leaking from its Web site back on August 2, 2017.

A long message thread that Houlihan shared between himself and Panera indicates that Mike Gustavison, Panera’s director of information security, initially dismissed Houlihan’s report as a likely scam. A week later, however, those messages suggest that the company had validated Houlihan’s findings and was working on a fix.

“Thank you for the information we are working on a resolution,” Gustavison wrote.

Panera was alerted about the data leakage in early August 2017, and said it was fixing the problem then.

Fast forward to early this afternoon — exactly eight months to the day after Houlihan first reported the problem — and data shared by Houlihan indicated the site was still leaking customer records in plain text. Worse still, the records could be indexed and crawled by automated tools with very little effort. Continue reading

Coinhive Exposé Prompts Cancer Research Fundraiser

March 30, 2018

A story published here this week revealed the real-life identity behind the original creator of Coinhive — a controversial cryptocurrency mining service that several security firms have recently labeled the most ubiquitous malware threat on the Internet today. In an unusual form of protest against that story, members of a popular German language image-posting board founded by the Coinhive creator have vented their dismay by donating tens hundreds of thousands of euros to local charities that support cancer research.

On Monday KrebsOnSecurity published Who and What is Coinhive, an in-depth story which proved that the founder of Coinhive was indeed the founder of the German image hosting and discussion forum pr0gramm[dot]com (not safe for work). I undertook the research because Coinhive’s code primarily is found on tens of thousands of hacked Web sites, and because the until-recently anonymous Coinhive operator(s) have been reluctant to take steps that might curb the widespread abuse of their platform.

One of countless pages of images posted about this author by pr0gramm users in response to the story about Coinhive.

In an early version of its Web site, Coinhive said its service was first tested on pr0gramm, and that the founder(s) of Coinhive considered pr0gramm “their platform” of 11 years (exactly the length of time pr0gramm has been online). Coinhive declined to say who was running their service, and tried to tell me their earlier statement about Coinhive’s longtime affiliation with pr0gramm was a convenient lie that was used to helped jump-start the service by enlisting the help of pr0gramm’s thousands of members.

Undeterred, I proceeded with my research based on the assumption that one or more of the founders of pr0gramm were involved in Coinhive. When I learned the real-life identities of the pr0gramm founders and approached them directly, each deflected questions about their apparent roles in founding and launching Coinhive.

However, shortly after the Coinhive story went live, the original founder of pr0gramm (Dominic Szablewski, a.k.a. “cha0s”) published a blog post acknowledging that he was in fact the creator of Coinhive. What’s more, Coinhive has since added legal contact information to its Web site, and has said it is now taking steps to ensure that it no longer profits from cryptocurrency mining activity after hacked Web sites owners report finding Coinhive’s code on their sites.

Normally, when KrebsOnSecurity publishes a piece that sheds light on a corner of the Internet that would rather remain in the shadows, the response is as predictable as it is swift: Distributed denial-of-service (DDoS) attacks on this site combined with threats of physical violence and harm from anonymous users on Twitter and other social networks.

While this site did receive several small DDoS attacks this week — and more than a few anonymous threats of physical violence and even death related to the Coinhive story — the response from pr0gramm members has been remarkably positive overall.

The pr0gramm community quickly seized on the fact that my last name — Krebs — means “crab” and “cancer” in German. Apparently urged by one of the pr0gramm founders named in the story to express their anger in “objective and polite” ways, several pr0gramm members took to donating money to the Deutsche Krebshilfe (German Cancer Aid/DKMS) Web site as a way to display their unity and numbers.

The protest (pr0test?) soon caught on in the Twitter hashtag “#KrebsIsCancer,” promoted and re-tweeted heavily by pr0gramm members as a means to “Fight Krebs” or fight cancer. According to a statement on DKMS’s Web site, the KrebsIsCancer campaign involved donations from more than 8,300 people totaling 207,500 euros (~USD $256,000).

Update, 2:46 p.m. ET: Updated donation figures per statement posted today on DKMS site.

Omitting the “o” in .com Could Be Costly

March 29, 2018

Take care when typing a domain name into a browser address bar, because it’s far too easy to fat-finger a key and wind up somewhere you don’t want to go. For example, if you try to visit some of the most popular destinations on the Web but omit the “o” in .com (and type .cm instead), there’s a good chance your browser will be bombarded with malware alerts and other misleading messages — potentially even causing your computer to lock up completely. As it happens, many of these domains appear tied to a marketing company whose CEO is a convicted felon and once self-proclaimed “Spam King.”

Matthew Chambers is a security professional and researcher in Atlanta. Earlier this month Chambers penned a post on his personal blog detailing what he found after several users he looks after accidentally mistyped different domains — such as espn[dot]cm.

Chambers said the user who visited that domain told him that after typing in espn.com he quickly had his computer screen filled with alerts about malware and countless other pop-ups. Security logs for that user’s system revealed the user had actually typed espn[dot]cm, but when Chambers reviewed the source code at that Web page he found an innocuous placeholder content page instead.

“One thing we notice is that any links generated off these domains tend to only work one time, if you try to revisit it’s a 404,” Chambers wrote, referring to the standard 404 message displayed in the browser when a Web page is not found. “The file is deleted to prevent researchers from trying to grab it, or automatic scanners from downloading it. Also, some of the exploit code on these sites will randomly vaporize, and they will have no code on them, but were just being weaponized in campaigns. It could be the user agent, or some other factor, but they definitely go dormant for periods of time.”

Espn[dot]cm is one of more than a thousand so-called “typosquatting” domains hosted on the same Internet address (85.25.199.30), including aetna[dot]cmaol[dot]cm, box[dot]cm, chase[dot]cm, citicards[dot]cmcostco[dot]cm, facebook[dot]cmgeico[dot]cm, hulu[dot]cmitunes[dot]cm, pnc[dot]cmslate[dot]cmsuntrust[dot]cm, turbotax[dot]cm, and walmart[dot]cm. I’ve compiled a partial list of the most popular typosquatting domains that are part of this network here (PDF).

KrebsOnSecurity sought to dig a bit deeper into Chambers’ findings, researching some of the domain registration records tied to the list of dot-cm typosquatting domains. Helpfully, all of the domains currently redirect visitors to just one of two landing pages — either antistrophebail[dot]com or chillcardiac[dot]com.

For the moment, if one visits either of these domains directly via a desktop Web browser (I’d advise against this) chances are the site will display a message saying, “Sorry, we currently have no promotions available right now.” Browsing some of them with a mobile device sometimes leads to a page urging the visitor to complete a “short survey” in exchange for “a chance to get an gift [sic] cards, coupons and other amazing deals!”

Those antistrophebail and chillcardiac domains — as well as 1,500+ others — were registered to the email address: ryanteraksxe1@yahoo.com. A Web search on that address doesn’t tell us much, but entering it at Yahoo‘s “forgot password” page lists a partially obfuscated address to which Yahoo can send an account key that may be used to reset the password for the account. That address is k*****ng@mediabreakaway[dot]com.

The full email address is kmanning@mediabreakaway[dot]com. According to the “leadership” page at mediabreakaway[dot]com, the email address ryanteraksxe1@yahoo.com almost certainly belongs to one Kacy Manning, who is listed as the “Manager of Special Projects” at Colorado based marketing firm Media Breakaway LLC.

Media Breakaway is headed by Scott Richter, a convicted felon who’s been successfully sued for spamming by some of the biggest media companies over the years. Continue reading

Who and What Is Coinhive?

March 26, 2018

Multiple security firms recently identified cryptocurrency mining service Coinhive as the top malicious threat to Web users, thanks to the tendency for Coinhive’s computer code to be used on hacked Web sites to steal the processing power of its visitors’ devices. This post looks at how Coinhive vaulted to the top of the threat list less than a year after its debut, and explores clues about the possible identities of the individuals behind the service.

Coinhive is a cryptocurrency mining service that relies on a small chunk of computer code designed to be installed on Web sites. The code uses some or all of the computing power of any browser that visits the site in question, enlisting the machine in a bid to mine bits of the Monero cryptocurrency.

Monero differs from Bitcoin in that its transactions are virtually untraceble, and there is no way for an outsider to track Monero transactions between two parties. Naturally, this quality makes Monero an especially appealing choice for cybercriminals.

Coinhive released its mining code last summer, pitching it as a way for Web site owners to earn an income without running intrusive or annoying advertisements. But since then, Coinhive’s code has emerged as the top malware threat tracked by multiple security firms. That’s because much of the time the code is installed on hacked Web sites — without the owner’s knowledge or permission.

Much like a malware infection by a malicious bot or Trojan, Coinhive’s code frequently locks up a user’s browser and drains the device’s battery as it continues to mine Monero for as long a visitor is browsing the site.

According to publicwww.com, a service that indexes the source code of Web sites, there are nearly 32,000 Web sites currently running Coinhive’s JavaScript miner code. It’s impossible to say how many of those sites have installed the code intentionally, but in recent months hackers have secretly stitched it into some extremely high-profile Web sites, including sites for such companies as The Los Angeles Times, mobile device maker Blackberry, Politifact, and Showtime.

And it’s turning up in some unexpected places: In December, Coinhive code was found embedded in all Web pages served by a WiFi hotspot at a Starbucks in Buenos Aires. For roughly a week in January, Coinhive was found hidden inside of YouTube advertisements (via Google’s DoubleClick platform) in select countries, including Japan, France, Taiwan, Italy and Spain. In February, Coinhive was found on “Browsealoud,” a service provided by Texthelp that reads web pages out loud for the visually impaired. The service is widely used on many UK government websites, in addition to a few US and Canadian government sites.

What does Coinhive get out of all this? Coinhive keeps 30 percent of whatever amount of Monero cryptocurrency that is mined using its code, whether or not a Web site has given consent to run it. The code is tied to a special cryptographic key that identifies which user account is to receive the other 70 percent.

Coinhive does accept abuse complaints, but it generally refuses to respond to any complaints that do not come from a hacked Web site’s owner (it mostly ignores abuse complaints lodged by third parties). What’s more, when Coinhive does respond to abuse complaints, it does so by invalidating the key tied to the abuse.

But according to Troy Mursch, a security expert who spends much of his time tracking Coinhive and other instances of “cryptojacking,” killing the key doesn’t do anything to stop Coinhive’s code from continuing to mine Monero on a hacked site. Once a key is invalidated, Mursch said, Coinhive keeps 100 percent of the cryptocurrency mined by sites tied to that account from then on.

Mursch said Coinhive appears to have zero incentive to police the widespread abuse that is leveraging its platform.

“When they ‘terminate’ a key, it just terminates the user on that platform, it doesn’t stop the malicious JavaScript from running, and it just means that particular Coinhive user doesn’t get paid anymore,” Mursch said. “The code keeps running, and Coinhive gets all of it. Maybe they can’t do anything about it, or maybe they don’t want to. But as long as the code is still on the hacked site, it’s still making them money.”

Reached for comment about this apparent conflict of interest, Coinhive replied with a highly technical response, claiming the organization is working on a fix to correct that conflict.

“We have developed Coinhive under the assumption that site keys are immutable,” Coinhive wrote in an email to KrebsOnSecurity. “This is evident by the fact that a site key can not be deleted by a user. This assumption greatly simplified our initial development. We can cache site keys on our WebSocket servers instead of reloading them from the database for every new client. We’re working on a mechanism [to] propagate the invalidation of a key to our WebSocket servers.”

AUTHEDMINE

Coinhive has responded to such criticism by releasing a version of their code called “AuthedMine,” which is designed to seek a Web site visitor’s consent before running the Monero mining scripts. Coinhive maintains that approximately 35 percent of the Monero cryptocurrency mining activity that uses its platform comes from sites using AuthedMine.

But according to a report published in February by security firm Malwarebytes, the AuthedMine code is “barely used” compared to the use of Coinhive’s mining code that does not seek permission from Web site visitors. Malwarebytes’ telemetry data (drawn from antivirus alerts when users browse to a site running Coinhive’s code) determined that AuthedMine is used in a little more than one percent of all cases that involve Coinhive’s mining code.

Image: Malwarebytes. The statistic above refer to the number of times per day between Jan. 10 and Feb. 7 that Malwarebytes blocked connections to AuthedMine and Coinhive, respectively.

Asked to comment on the Malwarebytes findings, Coinhive replied that if relatively few people are using AuthedMine it might be because anti-malware companies like Malwarebytes have made it unprofitable for people to do so.

“They identify our opt-in version as a threat and block it,” Coinhive said. “Why would anyone use AuthedMine if it’s blocked just as our original implementation? We don’t think there’s any way that we could have launched Coinhive and not get it blacklisted by Antiviruses. If antiviruses say ‘mining is bad,’ then mining is bad.”

Similarly, data from the aforementioned source code tracking site publicwww.com shows that some 32,000 sites are running the original Coinhive mining script, while the site lists just under 1,200 sites running AuthedMine.

WHO IS COINHIVE?

[Author’s’ note: Ordinarily, I prefer to link to sources of information cited in stories, such as those on Coinhive’s own site and other entities mentioned throughout the rest of this piece. However, because many of these links either go to sites that actively mine with Coinhive or that include decidedly not-safe-for-work content, I have included screenshots instead of links in these cases. For these reasons, I would strongly advise against visiting pr0gramm’s Web site.]

According to a since-deleted statement on the original version of Coinhive’s Web site — coin-hive[dot]com — Coinhive was born out of an experiment on the German-language image hosting and discussion forum pr0gramm[dot]com.

A now-deleted “About us” statement on the original coin-hive[dot]com Web site. This snapshop was taken on Sept. 15, 2017. Image courtesy archive.org.

Indeed, multiple discussion threads on pr0gramm[dot]com show that Coinhive’s code first surfaced there in the third week of July 2017. At the time, the experiment was dubbed “pr0miner,” and those threads indicate that the core programmer responsible for pr0miner used the nickname “int13h” on pr0gramm. In a message to this author, Coinhive confirmed that “most of the work back then was done by int13h, who is still on our team.”

I asked Coinhive for clarity on the disappearance of the above statement from its site concerning its affiliation with pr0gramm. Coinhive replied that it had been a convenient fiction:

“The owners of pr0gramm are good friends and we’ve helped them with their infrastructure and various projects in the past. They let us use pr0gramm as a testbed for the miner and also allowed us to use their name to get some more credibility. Launching a new platform is difficult if you don’t have a track record. As we later gained some publicity, this statement was no longer needed.”

Asked for clarification about the “platform” referred to in its statement (“We are self-funded and have been running this platform for the past 11 years”) Coinhive replied, “Sorry for not making it clearer: ‘this platform’ is indeed pr0gramm.”

After receiving this response, it occurred to me that someone might be able to find out who’s running Coinhive by determining the identities of the pr0gramm forum administrators. I reasoned that if they were not one and the same, the pr0gramm admins almost certainly would know the identities of the folks behind Coinhive. Continue reading

San Diego Sues Experian Over ID Theft Service

March 23, 2018

The City of San Diego, Calif. is suing consumer credit bureau Experian, alleging that a data breach first reported by KrebsOnSecurity in 2013 affected more than a quarter-million people in San Diego but that Experian never alerted affected consumers as required under California law.

The lawsuit, filed by San Diego city attorney Mara Elliott, concerns a data breach at an Experian subsidiary that lasted for nine months ending in 2013. As first reported here in October 2013, a Vietnamese man named Hieu Minh Ngo ran an identity theft service online and gained access to sensitive consumer information by posing as a licensed private investigator in the United States.

In reality, the fraudster was running his identity theft service from Vietnam, and paying Experian thousands of dollars in cash each month for access to 200 million consumer records. Ngo then resold that access to more than 1,300 customers of his ID theft service. KrebsOnSecurity first wrote about Ngo’s ID theft service — alternately called Superget[dot]info and Findget[dot]mein 2011.

Ngo was arrested after being lured out of Vietnam by the U.S. Secret Service. He later pleaded guilty to identity fraud charges and was sentenced in July 2015 to 13 years in prison.

News of the lawsuit comes from The San Diego Union-Tribune, which says the city attorney alleges that some 30 million consumers could have had their information stolen in the breach, including an estimated 250,000 people in San Diego.

“Elliott’s office cited the Internal Revenue Service in saying hackers filed more than 13,000 false returns using the hacked information, obtaining $65 million in fraudulent tax refunds,” writes Union-Tribune reporter Greg Moran.

Experian did not respond to requests for comment.

Ngo’s Identity theft service, superget.info, which relied on access to consumer databases maintained by a company that Experian purchased in 2012.

In December 2013, an executive from Experian told Congress that the company was not aware of any consumers who had been harmed by the incident. However, soon after Ngo was extradited to the United States, the Secret Service began identifying and rounding up dozens of customers of Ngo’s identity theft service. And most of Ngo’s customers were indeed involved in tax refund fraud with the states and the IRS. Continue reading
