UK Ad Campaign Seeks to Deter Cybercrime

May 28, 2020

The United Kingdom’s anti-cybercrime agency is running online ads aimed at young people who search the Web for services that enable computer crimes, specifically trojan horse programs and DDoS-for-hire services. The ad campaign follows a similar initiative launched in late 2017 that academics say measurably dampened demand for such services by explaining that their use to harm others is illegal and can land potential customers in jail.

For example, search in Google for the terms “booter” or “stresser” from a U.K. Internet address, and there’s a good chance you’ll see a paid ad show up on the first page of results warning that using such services to attack others online is illegal. The ads are being paid for by the U.K.’s National Crime Agency, which saw success with a related campaign for six months starting in December 2017.

A Google ad campaign paid for by the U.K.’s National Crime Agency.

NCA Senior Manager David Cox said the agency is targeting its ads to U.K. males age 13 to 22 who are searching for booter services or different types of remote access trojans (RATs), as part of an ongoing effort to help steer young men away from cybercrime and toward using their curiosity and skills for good. The ads link to advertorials and to the U.K.’s Cybersecurity Challenge, which tries gamify computer security concepts and highlight potential careers in cybersecurity roles.

“The fact is, those standing in front of a classroom teaching children have less information about cybercrime than those they’re trying to teach,” Cox said, noting that the campaign is designed to support so-called “knock-and-talk” visits, where investigators visit the homes of young people who’ve downloaded malware or purchased DDoS-for-hire services to warn them away from such activity. “This is all about showing people there are other paths they can take.”

While it may seem obvious to the casual reader that deploying some malware-as-a-service or using a booter to knock someone or something offline can land one in legal hot water, the typical profile of those who frequent these services is young, male, impressionable and participating in online communities of like-minded people in which everyone else is already doing it.

In 2017, the NCA published “Pathways into Cyber Crime,” a report that drew upon interviews conducted with a number of young men who were visited by U.K. law enforcement agents in connection with various cybercrime investigations.

Those findings, which the NCA said came about through knock-and-talk interviews with a number of suspected offenders, found that 61 percent of suspects began engaging in criminal hacking before the age of 16, and that the average age of suspects and arrests of those involved in hacking cases was 17 years old.

The majority of those engaged in, or on the periphery of, cyber crime, told the NCA they became involved via an interest in computer gaming.

A large proportion of offenders began to participate in gaming cheat websites and “modding” forums, and later progressed to criminal hacking forums.

The NCA learned the individuals visited had just a handful of primary motivations in mind, including curiosity, overcoming a challenge, or proving oneself to a larger group of peers. According to the report, a typical offender faces a perfect storm of ill-boding circumstances, including a perceived low risk of getting caught, and a perception that their offenses in general amounted to victimless crimes.

“Law enforcement activity does not act as a deterrent, as individuals consider cyber crime to be low risk,” the NCA report found. “Debrief subjects have stated that they did not consider law enforcement until someone they knew or had heard of was arrested. For deterrence to work, there must be a closing of the gap between offender (or potential offender) with law enforcement agencies functioning as a visible presence for these individuals.”

Cox said the NCA will continue to run the ads indefinitely, and that it is seeking funding from outside sources — including major companies in online gaming industry, whose platforms are perhaps the most targeted by DDoS-for-hire services. He called the program a “great success,” noting that in the past 30 days (13 of which the ads weren’t running for funding reasons), the ads generated some 5.32 million impressions, and more than 57,000 clicks.

FLATTENING THE CURVE

Richard Clayton is director of the University of Cambridge Cybercrime Centre, which has been monitoring DDoS attacks for several years using a variety of sensors across the Internet that pretend to be the types of systems which are typically commandeered and abused to help launch such assaults.

Last year, Clayton and fellow Cambridge researchers published a paper showing that law enforcement interventions — including the NCA’s anti-DDoS ad campaign between 2017 and 2018 — demonstrably slowed the growth in demand for DDoS-for-hire services.

“Our data shows that by running that ad campaign, the NCA managed to flatten out demand for booter services over that period,” Clayton said. “In other words, the demand for these services didn’t grow over the period as we would normally see, and we didn’t see more people doing it at the end of the period than at the beginning. When we showed this to the NCA, they were ever so pleased, because that campaign cost them less than ten thousand [pounds sterling] and it stopped this type of cybercrime from growing for six months.”

The Cambridge study found various interventions by law enforcement officials had measurable effects on the demand for and damage caused by booter and stresser services. Source: Booting the Booters, 2019.

Clayton said part of the problem is that many booter/stresser providers claim they’re offering lawful services, and many of their would-be customers are all too eager to believe this is true. Also, the price point is affordable: A typical booter service will allow customers to launch fairly high-powered DDoS attacks for just a few dollars per month.

“There are legitimate companies that provide these types of services in a legal manner, but there are all types of agreements that have to be in place before this can happen,” Clayton said. “And you don’t get that for ten bucks a month.” Continue reading →

Report: ATM Skimmer Gang Had Protection from Mexican Attorney General’s Office

May 26, 2020

A group of Romanians operating an ATM company in Mexico and suspected of bribing technicians to install sophisticated Bluetooth-based skimmers in cash machines throughout several top Mexican tourist destinations have enjoyed legal protection from a top anti-corruption official in the Mexican attorney general’s office, according to a new complaint filed with the government’s internal affairs division.

As detailed this week by the Mexican daily Reforma, several Mexican federal, state and municipal officers filed a complaint saying the attorney general office responsible for combating corruption had initiated formal proceedings against them for investigating Romanians living in Mexico who are thought to be part of the ATM skimming operation.

Reforma said the complaint centers on Camilo Constantino Rivera, who heads the unit in the Mexican Special Prosecutor’s office responsible for fighting corruption. It alleges Rivera has an inherent conflict of interest because his brother has served as a security escort and lawyer for Floridan Tudor, the reputed boss of a Romanian crime syndicate recently targeted by the FBI for running an ATM skimming and human trafficking network that operates throughout Mexico and the United States.

Tudor, a.k.a. “Rechinu” or “The Shark,” and his ATM company Intacash, were the subject of a three part investigation by KrebsOnSecurity published in September 2015. That series tracked the activities of a crime gang which was rumored to be bribing and otherwise coercing ATM technicians into installing Bluetooth-based skimming devices inside cash machines throughout popular tourist destinations in and around Mexico’s Yucatan Peninsula — including Cancun, Cozumel, Playa del Carmen and Tulum.

In 2018, 44-year-old Romanian national Sorinel Constantin Marcu was found shot dead in his car in Mexico. Marcu’s older brother told KrebsOnSecurity shortly after the murder that his brother was Tudor’s personal bodyguard but at some point had a falling out with Tudor and his associates over money. Marcu the elder said his brother was actually killed in front of a new apartment complex being built and paid for by Mr. Tudor, and that the dead man’s body was moved to make it look like he was slain in his car instead.

On March 31, 2019, police in Cancun, Mexico arrested 42-year-old Tudor and 37-year-old Adrian Nicholae Cosmin for the possession of an illegal firearm and cash totaling nearly 500,000 pesos (~USD $26,000) in both American and Mexican denominations. Two months later, a judge authorized the search of several of Tudor’s properties.

The Reforma report says Rivera’s office subsequently initiated proceedings against and removed several agents who investigated the crime ring, alleging those agents abused their authority and conducted illegal searches. The complaint against Rivera charges that the criminal protection racket also included the former chief of police in Cancun.

In September 2019, prosecutors with the Southern District of New York unsealed indictments and announced arrests against 18 people accused of running an ATM skimming and money laundering operation that netted $20 million. The defendants in that case — nearly all of whom are Romanians living in the United States and Mexico — included Florian Claudio Martin, described by Romanian newspapers as “the brother of Rechinu,” a.k.a. Tudor. Continue reading →

Riding the State Unemployment Fraud ‘Wave’

May 23, 2020
71 Comments

When a reliable method of scamming money out of people, companies or governments becomes widely known, underground forums and chat networks tend to light up with activity as more fraudsters pile on to claim their share. And that’s exactly what appears to be going on right now as multiple U.S. states struggle to combat a tsunami of phony Pandemic Unemployment Assistance (PUA) claims. Meanwhile, a number of U.S. states are possibly making it easier for crooks by leaking their citizens’ personal data from the very websites the unemployment scammers are using to file bogus claims.

Last week, the U.S. Secret Service warned of “massive fraud” against state unemployment insurance programs, noting that false filings from a well-organized Nigerian crime ring could end up costing the states and federal government hundreds of millions of dollars in losses.

Since then, various online crime forums and Telegram chat channels focused on financial fraud have been littered with posts from people selling tutorials on how to siphon unemployment insurance funds from different states.

Denizens of a Telegram chat channel newly rededicated to stealing state unemployment funds discussing cashout methods.

Yes, for roughly $50 worth of bitcoin, you too can quickly jump on the unemployment fraud “wave” and learn how to swindle unemployment insurance money from different states. The channel pictured above and others just like it are selling different “methods” for defrauding the states, complete with instructions on how best to avoid getting your phony request flagged as suspicious.

Although, at the rate people in these channels are “flexing” — bragging about their fraudulent earnings with screenshots of recent multiple unemployment insurance payment deposits being made daily — it appears some states aren’t doing a whole lot of fraud-flagging.

A still shot from a video a fraudster posted to a Telegram channel overrun with people engaged in unemployment insurance fraud shows multiple $800+ payments in one day from Massachusetts’ Department of Unemployment Assistance (DUA).

A federal fraud investigator who’s helping to trace the source of these crimes and who spoke with KrebsOnSecurity on condition of anonymity said many states have few controls in place to spot patterns in fraudulent filings, such as multiple payments going to the same bank accounts, or filings made for different people from the same Internet address.

In too many cases, he said, the deposits are going into accounts where the beneficiary name does not match the name on the bank account. Worse still, the source said, many states have dramatically pared back the amount of information required to successfully request an unemployment filing.

“The ones we’re seeing worst hit are the states that aren’t asking where you worked,” the investigator said. “It used to be they’d have a whole list of questions about your previous employer, and you had to show you were trying to find work. But now because of the pandemic, there’s no such requirement. They’ve eliminated any controls they had at all, and now they’re just shoveling money out the door based on Social Security number, name, and a few other details that aren’t hard to find.” Continue reading →

Ukraine Nabs Suspect in 773M Password ‘Megabreach’

May 19, 2020
27 Comments

In January 2019, dozens of media outlets raised the alarm about a new “megabreach” involving the release of some 773 million stolen usernames and passwords that was breathlessly labeled “the largest collection of stolen data in history.” A subsequent review by KrebsOnSecurity quickly determined the data was years old and merely a compilation of credentials pilfered from mostly public data breaches. Earlier today, authorities in Ukraine said they’d apprehended a suspect in the case.

The Security Service of Ukraine (SBU) on Tuesday announced the detention of a hacker known as Sanix (a.k.a. “Sanixer“) from the Ivano-Frankivsk region of the country. The SBU said they found on Sanix’s computer records showing he sold databases with “logins and passwords to e-mail boxes, PIN codes for bank cards, e-wallets of cryptocurrencies, PayPal accounts, and information about computers hacked for further use in botnets and for organizing distributed denial-of-service (DDoS) attacks.”

Sanix became famous last year for posting to hacker forums that he was selling the 87GB password dump, labeled “Collection #1.” Shortly after his sale was first detailed by Troy Hunt, who operates the HaveIBeenPwned breach notification service, KrebsOnSecurity contacted Sanix to find out what all the fuss was about. From that story:

“Sanixer said Collection#1 consists of data pulled from a huge number of hacked sites, and was not exactly his ‘freshest’ offering. Rather, he sort of steered me away from that archive, suggesting that — unlike most of his other wares — Collection #1 was at least 2-3 years old. His other password packages, which he said are not all pictured in the above screen shot and total more than 4 terabytes in size, are less than a year old, Sanixer explained.”

Alex Holden, chief technology officer and founder of Milwaukee-based Hold Security, said Sanixer’s claim to infamy was simply for disclosing the Collection #1 data, which was just one of many credential dumps amalgamated by other cyber criminals.

“Today, it is even a more common occurrence to see mixing new and old breached credentials,” Holden said. “In fact, large aggregations of stolen credentials have been around since 2013-2014. Even the original attempt to sell the Yahoo breach data was a large mix of several previous unrelated breaches. Collection #1 was one of many credentials collections output by various cyber criminals gangs.” Continue reading →

This Service Helps Malware Authors Fix Flaws in their Code

May 18, 2020
32 Comments

Almost daily now there is news about flaws in commercial software that lead to computers getting hacked and seeded with malware. But the reality is most malicious software also has its share of security holes that open the door for security researchers or ne’er-do-wells to liberate or else seize control over already-hacked systems. Here’s a look at one long-lived malware vulnerability testing service that is used and run by some of the Dark Web’s top cybercriminals.

It is not uncommon for crooks who sell malware-as-a-service offerings such as trojan horse programs and botnet control panels to include backdoors in their products that let them surreptitiously monitor the operations of their customers and siphon data stolen from victims. More commonly, however, the people writing malware simply make coding mistakes that render their creations vulnerable to compromise.

At the same time, security companies are constantly scouring malware code for vulnerabilities that might allow them peer to inside the operations of crime networks, or to wrest control over those operations from the bad guys. There aren’t a lot of public examples of this anti-malware activity, in part because it wades into legally murky waters. More importantly, talking publicly about these flaws tends to be the fastest way to get malware authors to fix any vulnerabilities in their code.

Enter malware testing services like the one operated by “RedBear,” the administrator of a Russian-language security site called Krober[.]biz, which frequently blogs about security weaknesses in popular malware tools.

For the most part, the vulnerabilities detailed by Krober aren’t written about until they are patched by the malware’s author, who’s paid a small fee in advance for a code review that promises to unmask any backdoors and/or harden the security of the customer’s product.

RedBear’s profile on the Russian-language xss[.]is cybercrime forum.

RedBear’s service is marketed not only to malware creators, but to people who rent or buy malicious software and services from other cybercriminals. A chief selling point of this service is that, crooks being crooks, you simply can’t trust them to be completely honest.

“We can examine your (or not exactly your) PHP code for vulnerabilities and backdoors,” reads his offering on several prominent Russian cybercrime forums. “Possible options include, for example, bot admin panels, code injection panels, shell control panels, payment card sniffers, traffic direction services, exchange services, spamming software, doorway generators, and scam pages, etc.”

As proof of his service’s effectiveness, RedBear points to almost a dozen articles on Krober[.]biz which explain in intricate detail flaws found in high-profile malware tools whose authors have used his service in the past, including; the Black Energy DDoS bot administration panel; malware loading panels tied to the Smoke and Andromeda bot loaders; the RMS and Spyadmin trojans; and a popular loan scam script.

ESTRANGED BEDFELLOWS

RedBear doesn’t operate this service on his own. Over the years he’s had several partners in the project, including two very high-profile cybercriminals (or possibly just one, as we’ll see in a moment) who until recently operated under the hacker aliases “upO” and “Lebron.”

From 2013 to 2016, upO was a major player on Exploit[.]in — one of the most active and venerated Russian-language cybercrime forums in the underground — authoring almost 1,500 posts on the forum and starting roughly 80 threads, mostly focusing on malware. For roughly one year beginning in 2016, Lebron was a top moderator on Exploit.

One of many articles Lebron published on Krober[.]biz that detailed flaws found in malware submitted to RedBear’s vulnerability testing service.

In 2016, several members began accusing upO of stealing source code from malware projects under review, and then allegedly using or incorporating bits of the code into malware projects he marketed to others.

up0 would eventually be banned from Exploit for getting into an argument with another top forum contributor, wherein both accused the other of working for or with Russian and/or Ukrainian federal authorities, and proceeded to publish personal information about the other that allegedly outed their real-life identities.

The cybercrime actor “upO” on Exploit[.]in in late 2016, complaining that RedBear was refusing to pay a debt owed to him.

Lebron first appeared on Exploit in September 2016, roughly two months before upO was banished from the community. After serving almost a year on the forum while authoring hundreds of posts and threads (including many articles first published on Krober), Lebron abruptly disappeared from Exploit.

His departure was prefaced by a series of increasingly brazen accusations by forum members that Lebron was simply upO using a different nickname. His final post on Exploit in May 2017 somewhat jokingly indicated he was joining an upstart ransomware affiliate program. Continue reading →

U.S. Secret Service: “Massive Fraud” Against State Unemployment Insurance Programs

May 16, 2020
147 Comments

A well-organized Nigerian crime ring is exploiting the COVID-19 crisis by committing large-scale fraud against multiple state unemployment insurance programs, with potential losses in the hundreds of millions of dollars, according to a new alert issued by the U.S. Secret Service.

A memo seen by KrebsOnSecurity that the Secret Service circulated to field offices around the United States on Thursday says the ring has been filing unemployment claims in different states using Social Security numbers and other personally identifiable information (PII) belonging to identity theft victims, and that “a substantial amount of the fraudulent benefits submitted have used PII from first responders, government personnel and school employees.”

“It is assumed the fraud ring behind this possesses a substantial PII database to submit the volume of applications observed thus far,” the Secret Service warned. “The primary state targeted so far is Washington, although there is also evidence of attacks in North Carolina, Massachusetts, Rhode Island, Oklahoma, Wyoming and Florida.”

The Secret Service said the fraud network is believed to consist of hundred of “mules,” a term used to describe willing or unwitting individuals who are recruited to help launder the proceeds of fraudulent financial transactions.

“In the state of Washington, individuals residing out-of-state are receiving multiple ACH deposits from the State of Washington Unemployment Benefits Program, all in different individuals’ names with no connection to the account holder,” the notice continues.

The Service’s memo suggests the crime ring is operating in much the same way as crooks who specialize in filing fraudulent income tax refund requests with the states and the U.S. Internal Revenue Service (IRS), a perennial problem that costs the states and the U.S. Treasury hundreds of millions of dollars in revenue each year.

In those schemes, the scammers typically recruit people — often victims of online romance scams or those who also are out of work and looking for any source of income — to receive direct deposits from the fraudulent transactions, and then forward the bulk of the illicit funds to the perpetrators.

A federal fraud investigator who spoke with KrebsOnSecurity on condition of anonymity said many states simply don’t have enough controls in place to detect patterns that might help better screen out fraudulent unemployment applications, such as looking for multiple applications involving the same Internet addresses and/or bank accounts. The investigator said in some states fraudsters need only to submit someone’s name, Social Security number and other basic information for their claims to be processed.

Elaine Dodd, executive vice president of the fraud division at the Oklahoma Bankers Association, said financial institutions in her state earlier this week started seeing a flood of high-dollar transfers tied to employment claims filed for people in Washington, with many transfers in the $9,000 to $20,000 range.

“It’s been unbelievable to see the huge number of bogus filings here, and in such large amounts,” Dodd said, noting that one fraudulent claim sent to a mule in Oklahoma was for more than $29,000. “I’m proud of our bankers because they’ve managed to stop a lot of these transfers, but some are already gone. Most mules seem to have [been involved in] romance scams.”

While it might seem strange that people in Washington would be asking to receive their benefits via ACH deposits at a bank in Oklahoma, Dodd said the people involved seem to have a ready answer if anyone asks: One common refrain is that the claimants live in Washington but were riding out the Coronavirus pandemic while staying with family in Oklahoma.

Microsoft Patch Tuesday, May 2020 Edition

May 12, 2020
34 Comments

Microsoft today issued software updates to plug at least 111 security holes in Windows and Windows-based programs. None of the vulnerabilities were labeled as being publicly exploited or detailed prior to today, but as always if you’re running Windows on any of your machines it’s time once again to prepare to get your patches on.

May marks the third month in a row that Microsoft has pushed out fixes for more than 110 security flaws in its operating system and related software. At least 16 of the bugs are labeled “Critical,” meaning ne’er-do-wells can exploit them to install malware or seize remote control over vulnerable systems with little or no help from users.

But focusing solely on Microsoft’s severity ratings may obscure the seriousness of the flaws being addressed this month. Todd Schell, senior product manager at security vendor Ivanti, notes that if one looks at the “exploitability assessment” tied to each patch — i.e., how likely Microsoft considers each can and will be exploited for nefarious purposes — it makes sense to pay just as much attention to the vulnerabilities Microsoft has labeled with the lesser severity rating of “Important.”

Virtually all of the non-critical flaws in this month’s batch earned Microsoft’s “Important” rating.

“What is interesting and often overlooked is seven of the ten [fixes] at higher risk of exploit are only rated as Important,” Schell said. “It is not uncommon to look to the critical vulnerabilities as the most concerning, but many of the vulnerabilities that end up being exploited are rated as Important vs Critical.”

For example, Satnam Narang from Tenable notes that two remote code execution flaws in Microsoft Color Management (CVE-2020-1117) and Windows Media Foundation (CVE-2020-1126) could be exploited by tricking a user into opening a malicious email attachment or visiting a website that contains code designed to exploit the vulnerabilities. However, Microsoft rates these vulnerabilities as “Exploitation Less Likely,” according to their Exploitability Index.

In contrast, three elevation of privilege vulnerabilities that received a rating of “Exploitation More Likely” were also patched, Narang notes. These include a pair of “Important” flaws in Win32k (CVE-2020-1054, CVE-2020-1143) and one in the Windows Graphics Component (CVE-2020-1135). Elevation of Privilege vulnerabilities are used by attackers once they’ve managed to gain access to a system in order to execute code on their target systems with elevated privileges. There are at least 56 of these types of fixes in the May release.

Schell says if your organization’s plan for prioritizing the deployment of this month’s patches stops at vendor severity or even CVSS scores above a certain level you may want to reassess your metrics.

“Look to other risk metrics like Publicly Disclosed, Exploited (obviously), and Exploitability Assessment (Microsoft specific) to expand your prioritization process,” he advised.

Ransomware Hit ATM Giant Diebold Nixdorf

May 11, 2020

Diebold Nixdorf, a major provider of automatic teller machines (ATMs) and payment technology to banks and retailers, recently suffered a ransomware attack that disrupted some operations. The company says the hackers never touched its ATMs or customer networks, and that the intrusion only affected its corporate network.

Canton, Ohio-based Diebold [NYSE: DBD] is currently the largest ATM provider in the United States, with an estimated 35 percent of the cash machine market worldwide. The 35,000-employee company also produces point-of-sale systems and software used by many retailers.

According to Diebold, on the evening of Saturday, April 25, the company’s security team discovered anomalous behavior on its corporate network. Suspecting a ransomware attack, Diebold said it immediately began disconnecting systems on that network to contain the spread of the malware.

Sources told KrebsOnSecurity that Diebold’s response affected services for over 100 of the company’s customers. Diebold said the company’s response to the attack did disrupt a system that automates field service technician requests, but that the incident did not affect customer networks or the general public.

“Diebold has determined that the spread of the malware has been contained,” Diebold said in a written statement provided to KrebsOnSecurity. “The incident did not affect ATMs, customer networks, or the general public, and its impact was not material to our business. Unfortunately, cybercrime is an ongoing challenge for all companies. Diebold Nixdorf takes the security of our systems and customer service very seriously. Our leadership has connected personally with customers to make them aware of the situation and how we addressed it.” Continue reading →

Meant to Combat ID Theft, Unemployment Benefits Letter Prompts ID Theft Worries

May 8, 2020
38 Comments

Millions of Americans now filing for unemployment will receive benefits via a prepaid card issued by U.S. Bank, a Minnesota-based financial institution that handles unemployment payments for more than a dozen U.S. states. Some of these unemployment applications will trigger an automatic letter from U.S. Bank to the applicant. The letters are intended to prevent identity theft, but many people are mistaking these vague missives for a notification that someone has hijacked their identity.

So far this month, two KrebsOnSecurity readers have forwarded scans of form letters they received via snail mail that mentioned an address change associated with some type of payment card, but which specified neither the entity that issued the card nor any useful information about the card itself.

Searching for snippets of text from the letter online revealed pages of complaints from consumers who appear confused about the source and reason for the letter, with most dismissing it as either a scam or considering it a notice of attempted identity theft. Here’s what’s the letter looks like:

A scan of the form letter sent by U.S. Bank to countless people enrolling in state unemployment benefits.

My first thought when a reader shared a copy of the letter was that he recently had been the victim of identity theft. It took a fair amount of digging online to discover that the nebulously named “Cardholder Services” address in Florida referenced at the top of the letter is an address exclusively used by U.S. Bank.

That digging indicated U.S. Bank currently manages the disbursement of funds for unemployment programs in at least 17 states, including Arkansas, Colorado, Delaware, Idaho, Louisiana, Maine, Minnesota, Nebraska, North Dakota, Ohio, Oregon, Pennsylvania, South Dakota, Texas, Utah, Wisconsin, and Wyoming. The funds are distributed through a prepaid debit card called ReliaCard.

To make matters more confusing, the flood of new unemployment applications from people out of work thanks to the COVID-19 pandemic reportedly has overwhelmed U.S. Bank’s system, meaning that many people receiving these letters haven’t yet gotten their ReliaCard and thus lack any frame of reference for having applied for a new payment card.

Reached for comment about the unhelpful letters, U.S. Bank said it automatically mails them to current and former ReliaCard customers when changes in its system are triggered by a customer – including small tweaks to an address — such as changing “Street” to “St.” Continue reading →

Tech Support Scam Uses Child Porn Warning

May 7, 2020
83 Comments

A new email scam is making the rounds, warning recipients that someone using their Internet address has been caught viewing child pornography. The message claims to have been sent from Microsoft Support, and says the recipient’s Windows license will be suspended unless they call an “MS Support” number to reinstate the license, but the number goes to a phony tech support scam that tries to trick callers into giving fraudsters direct access to their PCs.

The fraudulent message tries to seem more official by listing what are supposed to be the recipient’s IP address and MAC address. The latter term stands for “Media Access Control” and refers to a unique identifier assigned to a computer’s network interface.

However, this address is not visible to others outside of the user’s local network, and in any case the MAC address listed in the scam email is not even a full MAC address, which normally includes six groups of two alphanumeric characters separated by a colon. Also, the IP address cited in the email does not appear to have anything to do with the actual Internet address of the recipient.

Not that either of these details will be obvious to many people who receive this spam email, which states:

“We have found instances of child pornography accessed from your IP address & MAC Address.
IP Address: 206.19.86.255
MAC Address : A0:95:6D:C7

This is violation of Information Technology Act of 1996. For now we are Cancelling your Windows License, which means stopping all windows activities & updates on your computer.

If this was not You and would like to Reinstate the Windows License, Please call MS Support Team at 1-844-286-1916 for further help.

Microsoft Support
1 844 286 1916”

KrebsOnSecurity called the toll-free number in the email and was connected after a short hold to a man who claimed to be from MS Support. Immediately, he wanted me to type a specific Web addresses into my browser so he could take remote control over my computer. I was going to play along for a while but for some reason our call was terminated abruptly after several minutes. Continue reading →
