Attackers are breaking into Microsoft Windows computers using a newly discovered vulnerability in Internet Explorer, security experts warn. While the flaw appears to have been used mainly in targeted attacks so far, this vulnerability could become more widely exploited if incorporated into commercial crimeware kits sold in the underground.
It’s difficult to believe I’ve been doing this solo thing for so long, but as a thoughtful reader just reminded me, Dec. 29 marks the third anniversary of the KrebsOnSecurity.com blog! This past year, KrebsOnSecurity featured nearly 200 blog posts,… Read More »
Not long ago, PCs compromised by malware were put to a limited number of fraudulent uses, including spam, click fraud and denial-of-service attacks. These days, computer crooks are extracting and selling a much broader array of data stolen from hacked systems, including passwords and associated email credentials tied to a variety of online retailers.
The Department of Homeland Security’s U.S. Computer Emergency Readiness Team (US-CERT) is warning about a dangerous security hole in Adobe’s Shockwave Player that could be used to silently install malicious code. The truly shocking aspect of this bug? U.S. CERT first warned Adobe about the vulnerability in October 2010, and Adobe says it won’t be fixing it until February 2013.
If you hand your credit or debit card to a merchant who is using a wireless point-of-sale (POS) device, you may want to later verify that the charge actually went through. A top vendor of POS skimmers ships devices that will print out “transaction approved” receipts, even though the machine is offline and is merely recording the customer’s card data and PIN for future fraudulent use.
Customers of remote PC administration service LogMeIn.com and electronic signature provider DocuSign.com are complaining of a possible breach of customer information after receiving malware-laced emails to accounts they registered exclusively for use with those companies. Both companies say they are investigating the incidents, but so far have found no evidence of a security breach.
On Wednesday, the U.S. Justice Department announced that it had obtained convictions against a cybercrime gang that committed securities fraud through the use of botnets and spam. Oddly enough, none of the botmasters or spammers that assisted in the scheme were brought to justice or identified beyond their hacker handles. This blog post may change that.
“Project Blitzkrieg,” a brazen Underweb plan for hiring 100 botmasters to fuel a blaze of ebanking heists against 30 U.S. financial institutions in the Spring of 2013, was met with skepticism from some in the security community after news of the scheme came to light in October. Many assumed it was a law enforcement sting, or merely the ramblings of a wannabe criminal mastermind. But new research suggests the crooks who hatched the plan were serious and have painstakingly built up a formidable crime machine in preparation for the project.
Adobe and Microsoft have each released security updates to fix critical security flaws in their software. Microsoft issued seven update bundles to fix at least 10 vulnerabilities in Windows and other software. Separately, Adobe pushed out a fix for its Flash Player and AIR software that address at least three critical vulnerabilities in these programs.
Over the past 18 months, I’ve published a series of posts that provide clues about the possible real-life identities of the men responsible for building some of the largest and most disruptive spam botnets on the planet. I’ve since done a bit more digging into the backgrounds of the individuals thought to be responsible for the Rustock and Waledac spam botnets, which has produced some additional fascinating and corroborating details about these two characters.
