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 […]

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 […]

8 Tips for Filing Taxes Online Safely

by

By Mike Kronenberg Getting ready to file your taxes online — and doing it at the last minute? Well, cyber-scammers are ready for you. Thieves are schemers, and they’ve got a bag full of tricks to steal your identity. You might even be doing things to make their job easier. And if you use a PC at work to do your return,  identity theft could be as simple as a crook (or an unscrupulous coworker) digging around and finding sensitive files. One might send you an e-mail that offers a quick refund — or a warning about a problem with […]

Play it Safe on Safer Internet Day

by

February 9 marks Safer Internet Day, and around the world, people are trying to help their fellow netizens navigate an obstacle course of threats to their security and privacy. InSafe, the organization funded by the EU that sponsors the annual youth-targeted event, has themed the day around the concept “Think B4 U post.” As grammatically sloppy as that sounds, it’s actually good advice. Readers of this blog shouldn’t be surprised that myriad dangers threaten the safety of all Internet users: Keylogging software disguised as “updates” are everywhere; Fake security alerts pop up when you least expect them; Phishing Web pages […]

Zbot Fakes ABA Banking Site, Seeks a Stimulus Package

by

As the reign of nuisance by Trojan-Backdoor-Zbot continues, the latest scam invites victims to review a “transaction report” on a page supposedly on the Web site of the American Bankers Association, or ABA. (I wouldn’t want to call it a reign of terror; that might give the Zbot authors an inflated sense of their own importance. Zbot is like a wasp buzzing around the picnic table, and deserves a good, sharp smack, preferably with a shoe.) The “report” is, of course, an installer for this Trojan. The scam is virtually identical to ones we’ve seen where the scammer sets up […]

Visa Targeted (Again) by Zbot Phishers

by

The gang of malware distributors who are currently flooding the Internet with bogus Facebook “Update Tool,” CDC “H1N1 Flu Vaccination Profile,” and IRS “Tax Statement” emails and Web pages are at it again — this time, targeting Visa with a fake email alert that leads to a page hosting not only a Trojan-Backdoor-Zbot installer, but that performs a drive-by download as well. This is the second time in less than a month that malware distributors have targeted Visa; Just before Thanksgiving, we saw a similar scam involving links to bunk Verified By Visa Web pages. I’d say it’s ironic that […]

Bogus “New Moon” Torrents Lead to Malware

by

A week since the file-sharing clearinghouse Mininova changed its business model and deleted links to copyrighted material being shared over the peer-to-peer Bittorrent network, malware distributors continue to exploit the confusion as people who download movies, TV shows, and other shared files seek out new sources for those files. As a torrent search engine, Mininova had to deal with a significant number of malicious torrents posted to their site each day. The service had a reputation for rapidly deleting torrents which led to Trojaned applications, or maliciously crafted media files that lead file-sharing enthusiasts into infections. But in the ensuing […]

Fake Zbot Site Poses as CDC H1N1 Flu Vaccine Info

by

The newest victim of the faux-Web-sites-posing-as-government-pages scam is the Centers for Disease Control and Prevention. In the same vein as fake pages supposedly hosted on the Web servers of the IRS, FDIC, and other organizations, we’re seeing a new scam to infect computers with Trojan-Phisher-Zbot that pretends to be a “Personal H1N1 Vaccination Profile.” As with the previous scams, dozens of Web servers are involved. The URLs involved in the scheme all begin with the “http://online.cdc.gov” — the “online.” subdomain is not used by the CDC — followed by a six- to seven-character random domain name and a non-.gov top-level […]

Phishing Scheme Targets E-Payment Rule-Maker, NACHA

by

Coming on the heels of similar fraud schemes that targeted victims using the names of such familiar institutions as the FDIC, IRS, and HMRC, scammers are trying to get people to infect their own computer using a different organization’s name—one that is probably unfamiliar to most people. NACHA is a not-for-profit association that “oversees the Automated Clearing House (ACH) Network, a safe, efficient, green, and high-quality payment system.” In other words, they write the rules for the organizations that run the pipes through which money flows between banks and businesses–the circulatory system of the financial world. In fact, more than […]

Lazy Phishers Just Email the Phishing Web Page to You, Now

by

It was a particularly busy weekend for spammers, especially the creepy, evil ones who are trying to steal information (as opposed to the merely scungy pill vendors and their ilk). Webroot’s Threat Research team has recently seen a glut of phishing messages which, like most, purport to come from banks and ask you to update your account information. But unlike most phishing messages, which contain a link to a Web site, these phishing messages include an attached HTML file which, in essence, puts the phishing page right on your hard drive. When launched, the HTML file renders a sparse but effective phishing form […]
