Fake Amazon.com Order Emails Bring a Trojany “Friend”

by

An ongoing campaign where malware distributors use email spam to deliver dangerous programs to unwitting victims has begun to change its tune, switching the scam to incorporate different brands. In the latest scam, the message appears to be an order confirmation from Amazon.com for the purchase of an expensive consumer electronics item, or a contract (spelled, tellingly, “conract“) for expensive home improvement work, purportedly to be done on the recipient’s home. A few weeks ago, the emails switched from a “shipping confirmation” hook to one which claims the contents of the attachment include a code worth $50 on Apple’s iTunes […]

The Lessons of a ‘Love Bug’ Still Ring True

by

By Ian Moyse A decade on from the ILOVEYOU worm, what has changed—apart from ‘we’re older and (supposedly) wiser?’ We have allowed the bad in the real world to progressively infect our online world, giving criminals a way to attack victims that is more dangerous for the victim and, coincidentally, safer for the attacker. As recently as a decade ago, bank robbers had to physically enter the bank premises and overcome its defenses. Today, they simply need to be clever enough to trick you, rather than break the defenses of the bank itself. In humanizing the Internet we have dehumanized […]

Getting a “Conract” Doesn’t Make You a Rock Star

by

If you’re a rock-and-roll star, anticipating the imminent arrival of a new recording contract from your lawyer, you can stop reading this post. If you’re not, I’m sorry to be the one to tell you, it was not your hours of practice playing Rock Band, or singing in the shower, that attracted the attention of the music industry. A spammed message, supposedly from a record company, which claims to have a contract attached, is (surprise!) malicious. The contract, in this case, is no contract at all, but a Trojan that can brick your computer if you run the file inside […]

Cloud Defs Limit the Damage of a False Positive

by

If you’re a customer or an employee of McAfee, chances are, you’re having a rough week. The company published a false positive, or FP, in its antivirus definitions that went out to customers a few days ago. The FP resulted in some computers going into a loop where the antivirus engine misidentified a key component of the Windows operating system as malicious, Windows replaced the quarantined file, and then the McAfee engine removed it again. I really feel badly both for McAfee’s customers as well as their researchers. The customers certainly didn’t deserve or want their protection to go haywire. […]

Modified Websites Pushing Trojans On the Rise

by

For the past couple of weeks, owners of Web sites have been hit with a wave of attacks that surreptitiously infect unsuspecting visitors with a wide variety of malware types. The first wave inflicted rogue antivirus on unlucky victims, but late last week victims who visited infectious sites were redirected into a drive-by download site that pushes clickers onto a vulnerable visitor’s computer. The affected web sites have been modified to add malicious, obfuscated Javascript code to the footer of each page. Some Web hosts are trying to notify customers or fix the problems. At first, the problem affected sites […]

This PC Will Self-Destruct in Ten Seconds

by

Phishing Trojans that try to remain below the radar are still prevalent, but a number of files coming through Threat Research point to a disturbing trend: Several new variants of existing malware families are taking a scorched earth approach to infected computers, rendering the PC unbootable (just check out the batch file at left for just one egregious example) once the malware has retrieved whatever data it’s trying to steal, or deliberately crashing it, repeatedly, if you try to remove it. Since the middle of last year, we’ve seen a sprinkling of malware that also wipes out key files on […]
