10 Threats from 2010 We’d Prefer Remain History

by

With 2010 finally behind us, and an unknown number of cyberattacks likely to come in the new year, I thought I’d run down a brief list of the malicious campaigns criminals pulled off last year that I’d really dread to see anyone repeat. Now that they’re in the past, they should stay there. Operation Aurora: Google’s accusation (with Adobe, Juniper Networks, Rackspace, Yahoo! and Symantec) that China hacked its servers, allegedly stealing private emails stored on the company’s servers. The big surprise wasn’t that it was happening, but that companies were publicly talking about it. Abused ccTLDs: 2010 saw lots […]

Hey Malware Guy: Just What the Heck Am I Supposed to Do With This?

by

The Tacticlol downloader, responsible for a lot of infections over the past year, propagates in two ways: via drive-by downloads, and as a .zip archive attached to messages. Maybe the spam filtering companies finally caught on to the trick, or maybe the Tacticlol distributors are just trying to mix it up, but the latest sample to come over the transom has me scratching my head. Like most others, this sample came attached to an email made to look like a message that UPS would never send. Once again, the message tries to convince the recipient that the attached file is […]

Spammed Trojan Won’t Run Under Windows XP

by

While it is far from the first Trojan ever to simply fail to execute under Windows XP, it definitely caught our eye that a variant of Trojan-Downloader-Tacticlol distributed last week in a spam campaign only fully executed under Windows Vista or newer operating systems. It may have been just a fluke, but repeated tests with both a virtual machine and real hardware running Windows XP at various patch levels showed that the Trojan we received attached to a spam message simply quit when executed in an XP environment, but ran smoothly and did all its planned dirty work on a […]

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 […]

Trojan Masquerades as iTunes Gift or Résumé

by

If you received one or more email messages over the past week that claim to contain an attached gift certificate for the Apple iTunes store or an unsolicited résumé, you probably received the latest scam involving the Tacticlol downloader. The iTunes-themed spam messages use the forged return address of gifts.certificate@itunes.com and read, in part, You have received an iTunes Gift Certificate in the amount of $50.00. You can find your certificate code in the attachment below. The resume messages simply say Please review my CV, Thank you! — using the abbreviation for Curriculum Vitae, the British analogue to the word […]

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 […]

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 […]
