Microsoft today released security updates to fix almost a hundred security flaws in its various Windows operating systems and related software. One bug is so serious that Microsoft is issuing patches for it on Windows XP and other operating systems the company no longer officially supports. Separately, Adobe has pushed critical updates for its Flash and Shockwave players, two programs most users would probably be better off without.
A new report proves the value of following the money in the fight against dodgy cybercrime services known as “booters” or “stressers” — virtual hired muscle that can be rented to knock nearly any website offline.
Last fall, two 18-year-old Israeli men were arrested for allegedly running a vDOS, perhaps the most successful booter service of all time. The pair were detained within hours of being named in a story on this blog as the co-proprietors of the service (this site would later suffer a three-day outage as a result of an attack that was alleged to have been purchased in retribution for my reporting on vDOS).
That initial vDOS story was based on data shared by an anonymous source who had hacked vDOS and obtained its private user and attack database. The story showed how the service made approximately $600,000 over just two of the four years it was in operation. Most of those profits came in the form of credit card payments via PayPal.
But prior to vDOS’s takedown in September 2016, the service was already under siege thanks to work done by a group of academic researchers who teamed up with PayPal to identify and close accounts that vDOS and other booter services were using to process customer payments. The researchers found that their interventions cut profits in half for the popular booter service, and helped reduce the number of attacks coming out of it by at least 40 percent.
OneLogin, an online service that lets users manage logins to sites and apps from a single platform, says it has suffered a security breach in which customer data was compromised, including the ability to decrypt encrypted data.
Headquartered in San Francisco, OneLogin provides single sign-on and identity management for cloud-base applications. OneLogin counts among its customers some 2,000 companies in 44 countries, over 300 app vendors and more than 70 software-as-a-service providers.
For the second time in less than three years, Kmart Stores is battling a malware-based security breach of its store credit card processing systems.
Last week I began hearing from smaller banks and credit unions who said they strongly suspected another card breach at Kmart. Some of those institutions received alerts from the credit card companies about batches of stolen cards that all had one thing in comment: They were all used at Kmart locations.
Ask to respond to rumors about a card breach, Kmart’s parent company Sears Holdings said some of its payment systems were infected with malicious software:
It’s not uncommon for crooks who peddle stolen credit cards to seize on iconic American figures of wealth and power in the digital advertisements for these shops that run continuously on various cybercrime forums. Exhibit A: McDumpals, a hugely popular carding site that borrows the Ronald McDonald character from McDonald’s and caters to bulk buyers. Exhibit B: Uncle Sam’s dumps shop, which wants YOU! to buy American. Today, we’ll look at an up and coming credit card shop called Trump’s-Dumps, which invokes 45’s likeness and promises to “make credit card fraud great again.”
Earlier this month, KrebsOnSecurity featured a story about a basic security flaw in the Web site of medical diagnostics firm True Health Group that let anyone who was logged in to the site view all other patient records. In that story I mentioned True Health was one of three major healthcare providers with similar website problems, and that the other two providers didn’t even require a login to view all patient records. Today we’ll examine such a flaw that was just fixed by Molina Healthcare, a Fortune 500 company that until recently was exposing countless patient medical claims to the entire Internet without requiring any authentication.
A few weeks back, HR and financial management firm Workday.com sent a security advisory to customers warning that crooks were sending targeted malware phishing attacks at customers. At the same time, Workday is publishing on its site a list of more than 800 companies that use its services, making it relatively simple for attackers to chose their […]
In March 2017, KrebsOnSecurity warned that thieves who perpetrate tax refund fraud with the U.S. Internal Revenue Service were leveraging a widely-used online student loan tool to find critical data on consumers that allows them to claim huge refunds with the IRS in someone else’s name. This week, it emerged that a Louisiana-based private investigator is being charged with using the same online tool to glean tax data on then-presidential candidate Donald J. Trump.
A story today at Diverseeducation.com points to court filings in the U.S. District Court for the Middle District of Louisiana, in which local private eye Jordan Hamlett is accused by federal prosecutors of abusing an automated tool at the U.S. Department of Education website that is designed to make it easier for families to complete the Education Department’s Free Application for Federal Student Aid (FAFSA) — a lengthy form that serves as the starting point for students seeking federal financial assistance to pay for college or career school.
Identity thieves who specialize in tax refund fraud had big help this past tax year from Equifax, one of the nation’s largest consumer data brokers and credit bureaus. The trouble stems from TALX, an Equifax subsidiary that provides online payroll, HR and tax services. Equifax says crooks were able to reset the 4-digit PIN given to customer employees as a password and then steal W-2 tax data after successfully answering personal questions about those employees.
In a boilerplate text sent to several affected customers, Equifax said the unauthorized access to customers’ employee tax records happened between April 17, 2016 and March 29, 2017.
Beyond that, the extent of the fraud perpetrated with the help of hacked TALX accounts is unclear, and Equifax refused requests to say how many consumers or payroll service customers may have been impacted by the authentication weaknesses.
DocuSign, a major provider of electronic signature technology, acknowledged today that a series of recent malware phishing attacks targeting its customers and users was the result of a data breach at one of its computer systems. The company stresses that the data stolen was limited to customer and user email addresses, but the incident is especially dangerous because it allows attackers to target users who may already be expecting to click on links in emails from DocuSign.
