On Wednesday, the St. Louis Post-Dispatch ran a story about how its staff discovered and reported a security vulnerability in a Missouri state education website that exposed the Social Security numbers of 100,000 elementary and secondary teachers. In a press conference this morning, Missouri Gov. Mike Parson (R) said fixing the flaw could cost the state $50 million, and vowed his administration would seek to prosecute and investigate the “hackers” and anyone who aided the publication in its “attempt to embarrass the state and sell headlines for their news outlet.”Read More Missouri Governor Vows to Prosecute St. Louis Post-Dispatch for Reporting Security Vulnerability
A recent phishing campaign targeting Coinbase users shows thieves are getting cleverer about phishing one-time passwords (OTPs) needed to complete the login process. It also shows that phishers are attempting to sign up for new Coinbase accounts by the millions as part of an effort to identify email addresses that are already associated with active accounts.Read More How Coinbase Phishers Steal One-Time Passwords
Microsoft today issued updates to plug more than 70 security holes in its Windows operating systems and other software, including one vulnerability that is already being exploited in active attacks. This month’s Patch Tuesday also includes security fixes for the newly released Windows 11 operating system.Read More Patch Tuesday, October 2021 Edition
Facebook and its sister properties Instagram and WhatsApp are suffering from ongoing, global outages. We don’t yet know why this happened, but the how is clear: Earlier this morning, something inside Facebook caused the company to revoke key digital records that tell computers and other Internet-enabled devices how to find these destinations online.Read More What Happened to Facebook, Instagram, & WhatsApp?
The U.S. Federal Communications Commission (FCC) is asking for feedback on new proposed rules to crack down on SIM swapping and number port-out fraud, increasingly prevalent scams in which identity thieves hijack a target’s mobile phone number and use that to wrest control over the victim’s online identity.Read More FCC Proposal Targets SIM Swapping, Port-Out Fraud
In February, KrebsOnSecurity wrote about a novel cybercrime service that helped attackers intercept the one-time passwords (OTPs) that many websites require as a second authentication factor in addition to passwords. That service quickly went offline, but new research reveals a number of competitors have since launched bot-based services that make it relatively easy for crooks to phish OTPs from targets.Read More The Rise of One-Time Password Interception Bots
The new $30 Airtag tracking device from Apple has a feature that allows anyone who finds one of these tiny location beacons to scan it with a mobile phone and discover its owner’s phone number if the Airtag has been set to lost mode. But according to new research, this same feature can be abused to redirect the Good Samaritan to an iCloud phishing page — or to any other malicious website.Read More Apple AirTag Bug Enables ‘Good Samaritan’ Attack
In October 2016, media outlets reported that data collected by some of the world’s most renowned cybersecurity experts had identified frequent and unexplained communications between an email server used by the Trump Organization and Alfa Bank, one of Russia’s largest financial institutions. Those publications set off speculation about a possible secret back-channel of communications, as well as a series of lawsuits and investigations that culminated last week with the indictment of the same former federal cybercrime prosecutor who brought the data to the attention of the FBI five years ago.Read More Indictment, Lawsuits Revive Trump-Alfa Bank Story
It happens all the time: Organizations get hacked because there isn’t an obvious way for security researchers to let them know about security vulnerabilities or data leaks. Or maybe it isn’t entirely clear who should get the report when remote access to an organization’s internal network is being sold in the cybercrime underground.
In a bid to minimize these scenarios, a growing number of major companies are adopting “Security.txt,” a proposed new Internet standard that helps organizations describe their vulnerability disclosure practices and preferences.Read More Does Your Organization Have a Security.txt File?
A jury in California today reached a guilty verdict in the trial of Matthew Gatrel, a St. Charles, Ill. man charged in 2018 with operating two online services that allowed paying customers to launch powerful distributed denial-of-service (DDoS) attacks against Internet users and websites. Gatrel’s conviction comes roughly two weeks after his co-conspirator pleaded guilty to criminal charges related to running the services.Read More Trial Ends in Guilty Verdict for DDoS-for-Hire Boss

Microsoft today pushed software updates to plug dozens of security holes in Windows and related products, including a vulnerability that is already being exploited in active attacks. Also, Apple has issued an emergency update to fix a flaw that’s reportedly been abused to install spyware on iOS products, and Google’s got a new version of Chrome that tackles two zero-day flaws. Finally, Adobe has released critical security updates for Acrobat, Reader and a slew of other software.Read More Microsoft Patch Tuesday, September 2021 Edition
On Thursday evening, KrebsOnSecurity was the subject of a rather massive (and mercifully brief) distributed denial-of-service (DDoS) attack. The assault came from “Meris,” the same new “Internet of Things” (IoT) botnet behind record-shattering attacks against Russian search giant Yandex this week and internet infrastructure firm Cloudflare earlier this summer.Read More KrebsOnSecurity Hit By Huge New IoT Botnet “Meris”
Microsoft Corp. warned Tuesday that attackers are exploiting a previously unknown vulnerability in Windows 10 and many Windows Server versions to seize control over PCs when users open a malicious document or visit a booby-trapped website. There is currently no official patch for the flaw, but Microsoft has released recommendations for mitigating the threat.Read More Microsoft: Attackers Exploiting Windows Zero-Day Flaw
In May 2015, KrebsOnSecurity briefly profiled “The Manipulaters,” the name chosen by a prolific cybercrime group based in Pakistan that was very publicly selling spam tools and a range of services for crafting, hosting and deploying malicious email. Six years later, a review of the social media postings from this group shows they are prospering, while rather poorly hiding their activities behind a software development firm in Lahore that has secretly enabled an entire generation of spammers and scammers.Read More “FudCo” Spam Empire Tied to Pakistani Software Firm
Some of the most successful and lucrative online scams employ a “low-and-slow” approach — avoiding detection or interference from researchers and law enforcement agencies by stealing small bits of cash from many people over an extended period. Here’s the story of a cybercrime group that compromises up to 100,000 email inboxes per day, and apparently does little else with this access except siphon gift card and customer loyalty program data that can be resold online.Read More Gift Card Gang Extracts Cash From 100k Inboxes Daily
Over the past 15 years, a cybercrime anonymity service known as VIP72 has enabled countless fraudsters to mask their true location online by routing their traffic through millions of malware-infected systems. But roughly two week ago, VIP72’s online storefront — which sold access to more than 30,000 compromised PCs — simply vanished.Read More 15-Year-Old Malware Proxy Network VIP72 Goes Dark
In 2018, Andrew Schober was digitally mugged for approximately $1 million worth of bitcoin. After several years of working with investigators, Schober says he’s confident he has located two young men in the United Kingdom responsible for developing a clever piece of digital clipboard-stealing malware that let them siphon his crypto holdings. Schober is now suing each of their parents in a civil case that seeks to extract what their children would not return voluntarily.Read More Man Robbed of 16 Bitcoin Sues Young Thieves’ Parents
Criminal hackers will try almost anything to get inside a profitable enterprise and secure a million-dollar payday from a ransomware infection. Apparently now that includes emailing employees directly and asking them to unleash the malware inside their employer’s network in exchange for a percentage of any ransom amount paid by the victim company.Read More Wanted: Disgruntled Employees to Deploy Ransomware
T-Mobile warned Monday that a data breach has exposed the names, date of birth, Social Security number and driver’s license/ID information of more than 40 million current, former or prospective customers. The acknowledgment came less than 48 hours after millions of the stolen T-Mobile customer records went up for sale in the cybercrime underground.Read More T-Mobile: Breach Exposed SSN/DOB of 40M+ People
Communications giant T-Mobile said today it is investigating the extent of a data breach that hackers claim has exposed sensitive personal data on 100 million T-Mobile USA customers, in many cases including the name, Social Security number, address, date of birth, phone number, security PINs and details that uniquely identify each customer’s mobile device.Read More T-Mobile Investigating Claims of Massive Data Breach
Two new dark web services are marketing to cybercriminals who are curious to see how their various cryptocurrency holdings and transactions may be linked to known criminal activity. Dubbed “Antinalysis” and “AMLBot,” the services purport to offer a glimpse into how one’s payment activity might be flagged by law enforcement agencies and private companies that try to link suspicious cryptocurrency transactions to real people.Read More New Anti Anti-Money Laundering Services for Crooks
Microsoft today released software updates to plug at least 44 security vulnerabilities in its Windows operating systems and related products. The software giant warned that attackers already are pouncing on one of the flaws, which ironically enough involves an easy-to-exploit bug in the software component responsible for patching Windows 10 PCs and Windows Server 2019 machines.Read More Microsoft Patch Tuesday, August 2021 Edition
I was preparing to knock off work on a recent Friday evening when a curious and annoying email came in via the contact form on this site:
“Hello I go by the username Nuclear27 on your site Briansclub[.]com,” wrote “Mitch,” confusing me with the proprietor of perhaps the underground’s largest bazaar for stolen credit and identity data. “I made a deposit to my wallet on the site but nothing has shown up yet and I would like to know why.”
Several things stood out in Mitch’s message. For starters, that is not the actual domain for BriansClub. And it’s not hard to see why Mitch got snookered: The real BriansClub site is currently not at the top of search results when one queries that shop name at Google.Read More Phishing Sites Targeting Scammers and Thieves
It’s nice when ransomware gangs have their bitcoin stolen, malware servers shut down, or are otherwise forced to disband. We hang on to these occasional victories because history tells us that most ransomware moneymaking collectives don’t go away so much as reinvent themselves under a new name, with new rules, targets and weaponry. Indeed, some of the most destructive and costly ransomware groups are now in their third incarnation over as many years.
Reinvention is a basic survival skill in the cybercrime business. Among the oldest tricks in the book is to fake one’s demise or retirement and invent a new identity. A key goal of such subterfuge is to throw investigators off the scent or to temporarily direct their attention elsewhere.
Cybercriminal syndicates also perform similar disappearing acts whenever it suits them. These organizational reboots are an opportunity for ransomware program leaders to set new ground rules for their members — such as which types of victims aren’t allowed (e.g., hospitals, governments, critical infrastructure), or how much of a ransom payment an affiliate should expect for bringing the group access to a new victim network.Read More Ransomware Gangs and the Name Game Distraction
Microsoft today released fixes to plug at least 55 security holes in its Windows operating systems and other software. Four of these weaknesses can be exploited by malware and malcontents to seize complete, remote control over vulnerable systems without any help from users. On deck this month are patches to quash a wormable flaw, a creepy wireless bug, and yet another reason to call for the death of Microsoft’s Internet Explorer (IE) web browser.Read More Microsoft Patch Tuesday, May 2021 Edition
The FBI confirmed this week that a relatively new ransomware group known as DarkSide is responsible for an attack that caused Colonial Pipeline to shut down 5,550 miles of pipe, stranding countless barrels of gasoline, diesel and jet fuel on the Gulf Coast. Here’s a closer look at the DarkSide cybercrime gang, as seen through their negotiations with a recent U.S. victim that earns $15 billion in annual revenue.Read More A Closer Look at the DarkSide Ransomware Gang
How much is your payroll data worth? Probably a lot more than you think. One financial startup that’s targeting the gig worker market is offering up to $500 to anyone willing to hand over the payroll account username and password given to them by their employer, plus a regular payment for each month afterwards in which those credentials still work.Read More Fintech Startup Offers $500 for Payroll Passwords
John Bernard, a pseudonym used by a convicted thief and con artist named John Clifton Davies who’s fleeced dozens of technology startups out of an estimated $30 million, appears to have reinvented himself again after being exposed in a recent investigative series published here. Sources tell KrebsOnSecurity that Davies/Bernard is now posing as John Cavendish and head of a new “private office” called Hempton Business Management LLP.Read More Investment Scammer John Davies Reinvents Himself?
Phishers targeting Microsoft Office 365 users increasingly are turning to specialized links that take users to their organization’s own email login page. After a user logs in, the link prompts them to install a malicious but innocuously-named app that gives the attacker persistent, password-free access to any of the user’s emails and files, both of which are then plundered to launch malware and phishing scams against others.Read More Malicious Office 365 Apps Are the Ultimate Insiders
When normal computer users fall into the nasty habit of recycling passwords, the result is most often some type of financial loss. When cybercriminals develop the same habit, it can eventually cost them their freedom.Read More The Wages of Password Re-use: Your Money or Your Life
Some of the world’s top tech firms are backing a new industry task force focused on disrupting cybercriminal ransomware gangs by limiting their ability to get paid, and targeting the individuals and finances of the organized thieves behind these crimes.Read More Task Force Seeks to Disrupt Ransomware Payments
Big-three consumer credit bureau Experian just fixed a weakness with a partner website that let anyone look up the credit score of tens of millions of Americans just by supplying their name and mailing address, KrebsOnSecurity has learned. Experian says it has plugged the data leak, but the researcher who reported the finding says he fears the same weakness may be present at countless other lending websites that work with the credit bureau.Read More Experian API Exposed Credit Scores of Most Americans
In 2017, KrebsOnSecurity showed how easy it is for identity thieves to undo a consumer’s request to freeze their credit file at Experian, one of the big three consumer credit bureaus in the United States. Last week, KrebsOnSecurity heard from a reader who had his freeze thawed without authorization through Experian’s website, and it reminded me of how truly broken authentication and security remains in the credit bureau space.Read More Experian’s Credit Freeze Security is Still a Joke
What was the best news you heard so far this month? Mine was learning that KrebsOnSecurity is listed as a restricted competitor by Gartner Inc. [NYSE:IT] — a $4 billion technology goliath whose analyst reports can move markets and shape the IT industry.Read More Note to Self: Create Non-Exhaustive List of Competitors
On Aug. 13, 2020, someone uploaded a suspected malicious file to VirusTotal, a service that scans submitted files against more than five dozen antivirus and security products. Last month, Microsoft and FireEye identified that file as a newly-discovered fourth malware backdoor used in the sprawling SolarWinds supply chain hack. An analysis of the malicious file and other submissions by the same VirusTotal user suggest the account that initially flagged the backdoor as suspicious belongs to IT personnel at the National Telecommunications and Information Administration (NTIA), a division of the U.S. Commerce Department that handles telecommunications and Internet policy.Read More Did Someone at the Commerce Dept. Find a SolarWinds Backdoor in Aug. 2020?
Microsoft today released updates to plug at least 110 security holes in its Windows operating systems and other products. The patches include four security fixes for Microsoft Exchange Server — the same systems that have been besieged by attacks on four separate (and zero-day) bugs in the email software over the past month. Redmond also patched a Windows flaw that is actively being exploited in the wild.Read More Microsoft Patch Tuesday, April 2021 Edition
Someone is selling account information for 21 million customers of ParkMobile, a mobile parking app that’s popular in North America. The stolen data includes customer email addresses, phone numbers, license plate numbers, hashed passwords and mailing addresses.Read More ParkMobile Breach Exposes License Plate Data, Mobile Numbers of 21M Users
Ne’er-do-wells leaked personal data — including phone numbers — for some 553 million Facebook users this week. Facebook says the data was collected before 2020 when it changed things to prevent such information from being scraped from profiles. To my mind, this just reinforces the need to remove mobile phone numbers from all of your online accounts wherever feasible. Meanwhile, if you’re a Facebook product user and want to learn if your data was leaked, there are easy ways to find out.Read More Are You One of the 533M People Who Got Facebooked?
Some of the top ransomware gangs are deploying a new pressure tactic to push more victim organizations into paying an extortion demand: Emailing the victim’s customers and partners directly, warning that their data will be leaked to the dark web unless they can convince the victim firm to pay up.Read More Ransom Gangs Emailing Victim Customers for Leverage
For four days this past week, Internet-of-Things giant Ubiquiti failed to respond to requests for comment on a whistleblower’s allegations that the company had massively downplayed a “catastrophic” two-month breach ending in January to save its stock price, and that Ubiquiti’s insinuation that a third-party was to blame was a fabrication. I was happy to add their eventual public response to the top of Tuesday’s story on the whistleblower’s claims, but their statement deserves a post of its own because it actually confirms and reinforces those claims.Read More Ubiquiti All But Confirms Breach Response Iniquity
The U.S. Labor Department’s inspector general said this week that roughly $100 million in fraudulent unemployment insurance claims were paid in 2020 to criminals who are already in jail. That’s a tiny share of the estimated tens of billions of dollars in jobless benefits states have given to identity thieves in the past year. To help reverse that trend, many states are now turning to a little-known private company called ID.me. This post examines some of what that company is seeing in its efforts to stymie unemployment fraud.Read More How $100M in Jobless Claims Went to Inmates
Easily the most sophisticated skimming devices made for hacking terminals at retail self-checkout lanes are a new breed of PIN pad overlay combined with a flexible, paper-thin device that fits inside the terminal’s chip reader slot. What enables these skimmers to be so slim? They draw their power from the low-voltage current that gets triggered when a chip-based card is inserted. As a result, they do not require external batteries, and can remain in operation indefinitely.Read More Checkout Skimmers Powered by Chip Cards
The leader of Mexico’s Green Party has been removed from office following allegations that he received money from a Romanian ATM skimmer gang that stole hundreds of millions of dollars from tourists visiting Mexico’s top tourist destinations over the past five years. The scandal is the latest fallout stemming from a three-part investigation into the organized crime group by KrebsOnSecurity in 2015.Read More Mexican Politician Removed Over Alleged Ties to Romanian ATM Skimmer Gang
The U.S. Justice Department today unsealed indictments against three men accused of working with the North Korean regime to carry out some of the most damaging cybercrime attacks over the past decade, including the 2014 hack of Sony Pictures, the global WannaCry ransomware contagion of 2017, and the theft of roughly $200 million and attempted theft of more than $1.2 billion from banks and other victims worldwide.Read More U.S. Indicts North Korean Hackers in Theft of $200 Million
As a total sucker for anything skimming-related, I was interested to hear from a reader working security for a retail chain in the United States that recently found bluetooth-enabled skimming devices placed over top of payment card terminals at several stores. Interestingly, these skimmers interfered with the terminal’s ability to read chip-based cards, forcing customers to swipe the stripe instead.Read More Bluetooth Overlay Skimmer That Blocks Chip
Stories about computer security tend to go viral when they bridge the vast divide between geeks and luddites, and this week’s news about a hacker who tried to poison a Florida town’s water supply was understandably front-page material. But for security nerds who’ve been warning about this sort of thing for ages, the most surprising aspect of the incident seems to be that we learned about it at all.Read More What’s most interesting about the Florida water system hack? That we heard about it at all.
Microsoft today rolled out updates to plug at least 56 security holes in its Windows operating systems and other software. One of the bugs is already being actively exploited, and six of them were publicized prior to today, potentially giving attackers a head start in figuring out how to exploit the flaws.Read More Microsoft Patch Tuesday, February 2021 Edition
Cyber cops in Ukraine carried out an arrest and several raids last week in connection with the author of a U-Admin, a software package used to administer what’s being called “one of the world’s largest phishing services.” The operation was carried out in coordination with the FBI and authorities in Australia, which was particularly hard hit by phishing scams perpetrated by U-Admin customers.Read More Arrest, Raids Tied to ‘U-Admin’ Phishing Kit
Facebook, Instagram, TikTok, and Twitter this week all took steps to crack down on users involved in trafficking hijacked user accounts across their platforms. The coordinated action seized hundreds of accounts the companies say have played a major role in facilitating the trade and often lucrative resale of compromised, highly sought-after usernames.Read More Facebook, Instagram, TikTok and Twitter Target Resellers of Hacked Accounts
ValidCC, a dark web bazaar run by a cybercrime group that for more than six years hacked online merchants and sold stolen payment card data, abruptly closed up shop last week. The proprietors of the popular store said their servers were seized as part of a coordinated law enforcement operation designed to disconnect and confiscate its infrastructure.Read More ‘ValidCC,’ a Major Payment Card Bazaar and Looter of E-Commerce Sites, Shuttered
Authorities in the United Kingdom have arrested a 20-year-old man for allegedly operating an online service for sending high-volume phishing campaigns via mobile text messages. The service, marketed in the underground under the name “SMS Bandits,” has been responsible for blasting out huge volumes of phishing lures spoofing everything from COVID-19 pandemic relief efforts to PayPal, telecommunications providers and tax revenue agencies.Read More U.K. Arrest in ‘SMS Bandits’ Phishing Service
The unprecedented volume of unemployment insurance fraud witnessed in 2020 hasn’t abated, although news coverage of the issue has largely been pushed off the front pages by other events. But the ID theft problem is coming to the fore once again: Countless Americans will soon be receiving notices from state regulators saying they owe thousands of dollars in taxes on benefits they never received last year.Read More The Taxman Cometh for ID Theft Victims
U.S. and Bulgarian authorities this week seized the darkweb site used by the NetWalker ransomware cybercrime group to publish data stolen from its victims. In connection with the seizure, a Canadian national suspected of extorting more than $27 million through the spreading of NetWalker was charged in a Florida court.Read More Arrest, Seizures Tied to Netwalker Ransomware
Authorities across Europe on Tuesday said they’d seized control over Emotet, a prolific malware strain and cybercrime-as-service operation. Investigators say the action could help quarantine more than a million Microsoft Windows systems currently compromised with malware tied to Emotet infections.Read More International Action Targets Emotet Crimeware
Parler, the beleaguered social network advertised as a “free speech” alternative to Facebook and Twitter, has had a tough month. Apple and Google removed the Parler app from its stores, and Amazon blocked the platform from using its hosting services. Parler has since found a home in DDoS-Guard, a Russian digital infrastructure company. But now it appears DDoS-Guard is about to be relieved of more than two-thirds of the Internet address space the company leases to clients — including the Internet addresses currently occupied by Parler.Read More DDoS-Guard To Forfeit Internet Space Occupied by Parler
