Earlier today, KrebsOnSecurity alerted the 10th largest food distributor in the United States that one of its Web sites had been hacked and retrofitted with code that steals credit card and login data. While such Web site card skimming attacks are not new, this intrusion leveraged a sneaky new domain that hides quite easily in a hacked site’s source code: “http[.]ps” (the actual malicious domain does not include the brackets, which are there to keep readers from being able to click on it).
Microsoft Corp. today released updates to plug more than 100 security holes in its various Windows operating systems and associated software. If you (ab)use Windows, please take a moment to read this post, backup your system(s), and patch your PCs.
FBI officials last week arrested a Russian computer security researcher on suspicion of operating deer.io, a vast marketplace for buying and selling stolen account credentials for thousands of popular online services and stores.
Kirill V. Firsov was arrested Mar. 7 after arriving at New York’s John F. Kennedy Airport, according to court documents unsealed Monday. Prosecutors with the U.S. District Court for the Southern District of California allege Firsov was the administrator of deer.io, an online platform that hosted more than 24,000 shops for selling stolen and/or hacked usernames and passwords for a variety of top online destinations.
The federal agency in charge of issuing .gov domain names is enacting new requirements for validating the identity of people requesting them. The additional measures come less than four months after KrebsOnSecurity published research suggesting it was relatively easy for just about anyone to get their very own .gov domain.
In November’s piece It’s Way Too Easy to Get a .gov Domain Name, an anonymous source detailed how he obtained one by impersonating an official at a small town in Rhode Island that didn’t already have its own .gov.
Last week, KrebsOnSecurity reported to health insurance provider Blue Shield of California that its Web site was flagged by multiple security products as serving malicious content. Blue Shield quickly removed the unauthorized code. An investigation determined it was injected by a browser extension installed on the computer of a Blue Shield employee who’d edited the Web site in the past month.
The incident is a reminder that browser extensions — however useful or fun they may seem when you install them — typically have a great deal of power and can effectively read and/or write all data in your browsing sessions. And as we’ll see, it’s not uncommon for extension makers to sell or lease their user base to shady advertising firms, or in some cases abandon them to outright cybercriminals.
A large number of French critical infrastructure firms were hacked as part of an extended malware campaign that appears to have been orchestrated by at least one attacker based in Morocco, KrebsOnSecurity has learned. The individual thought to be involved has earned accolades from the likes of Apple, Dell, and Microsoft for helping to find and fix security vulnerabilities in their products.
