In a move that may wind up helping spammers, Microsoft is blaming a new Canadian anti-spam law for the company’s recent decision to stop sending regular emails about security updates for its Windows operating system and other Microsoft software.
The year 2014 may well go down in the history books as the year that extortion attacks went mainstream. Fueled largely by the emergence of the anonymous online currency bitcoin, these modern-day shakedowns are blurring the lines between online and offline fraud, and giving novice computer users a crash course in modern-day cybercrime.
The Internet of Things is coming….to a highway sign near you? In the latest reminder that much of our nation’s “critical infrastructure” is held together with the Internet equivalent of spit and glue, authorities in several U.S. states are reporting that a hacker has once again broken into and defaced electronic road signs over highway in several U.S. states.
Over the past year, I’ve spent a great deal of time trolling a variety of underground stores that sell “dumps” — street slang for stolen credit card data that buyers can use to counterfeit new cards and go shopping in big-box stores for high-dollar merchandise that can be resold quickly for cash. By way of explaining this bizarro world, this post takes the reader on a tour of a rather exclusive and professional dumps shop that caters to professional thieves, high-volume buyers and organized crime gangs.
The U.S. Justice Department is expected to announce today an international law enforcement operation to seize control over the Gameover ZeuS botnet, a sprawling network of hacked Microsoft Windows computers that currently infects an estimated 500,000 to 1 million compromised systems globally. Experts say PCs infected with Gameover are being harvested for sensitive financial and personal data, and rented out to an elite cadre of hackers for use in online extortion attacks, spam and other illicit moneymaking schemes.
Researchers have uncovered an extremely critical vulnerability in recent versions of OpenSSL, a technology that allows millions of Web sites to encrypt communications with visitors. Complicating matters further is the release of a simple exploit that can be used to steal usernames and passwords from vulnerable sites, as well as private keys that sites use to encrypt and decrypt sensitive data.
A new rash of credit and debit card scams involving bogus sub-$15 charges and attributed to a company called “BLS Weblearn” is part of a prolific international scheme designed to fleece unwary consumers. This post delves deeper into the history and identity of the credit card processing network that has been enabling this type of activity for years.
Earlier this month, beauty products chain Sally Beauty acknowledged that a hacker break-in compromised fewer than 25,000 customer credit and debit cards. My previous reporting indicated that the true size of the breach was at least ten times larger. While the number of cards known to be compromised so far pales in comparison to the 40 million cards exposed by the breach at some 1,800 Target locations, new analysis suggests that the Sally Beauty breach may have impacted far more stores –virtually all 2,600+ Sally Beauty locations nationwide.
Microsoft warned today that attackers are exploiting a previously unknown security hole in Microsoft Word that can be used to foist malicious code if users open a specially crafted text file, or merely preview the message in Microsoft Outlook.
On Wednesday, KrebsOnSecurity was hit with a fairly large attack which leveraged a feature in more than 42,000 blogs running the popular WordPress content management system (this blog runs on WordPress).
