Botnet Trojan Adds “Gootkit” Code to Web Pages

by

An insidious new Trojan that finds its way onto Windows PCs in the course of a drive-by infection employs a novel method to propagate: It connects to Web servers using stolen FTP credentials, and if successful, modifies any HTML and PHP files with extra code. The code opens an iFrame pointing to a page that loads browser exploits. The exploit pushes down the infection, which then perpetuates the process. The initial infection vector in this case was a spam message supposedly from Amazon.com containing a link to the page which performs the drive-by attacks. The malware, which we’re calling Trojan-Backdoor-Protard, […]

British Music Awards Draws Web Scams

by

Music fans may already be aware that next Tuesday the British music industry will honor the top acts of the year at a ceremony known simply as The BRITs. What they may not know is that common Internet criminals have begun to target people searching for information about the artists and the music connected with the awards for attack. This will be the 30th ceremony held in the 33 year history of the awards. As in previous years, the BRIT Trust (a charity run by BPI, the UK’s recording industry trade association) will donate profits from the ceremony, including the […]

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 […]

Fakealerts Invade Google Image Search Results for ’24′ Star

by

Searchers beware: Those photos of celebrities or funny cat pictures that turn up in your Google image search results might not be photos at all, but fake antivirus alerts. Evidence appears to indicate that a similar scam to one we blogged about last November may be working its way up the Google food chain into other forms of search results. While searching for photos of Annie Wersching, an actress who recently joined the cast of the TV show 24, we stumbled into one of these javascript-enabled fakealert browser traps. Oddly enough, when you click one of these bogus linked pictures […]

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 […]

Rogue AV Payload Blocks Popular Websites

by

A payload file installed along with some variants of the rogue Internet Security 2010 “antivirus” program modifies victims’ networking settings within Windows, inserting itself into the network stack and preventing victims from visiting some of the Web’s most popular Web sites. More than 40 sites have been targeted, including: Microsoft’s live.com and Bing search engine; social networking giants Facebook, Twitter, MySpace, Bebo, LinkedIn, and YouTube; news organizations including Fox News, The New York Times, the Washington Post, and the UK’s Guardian and BBC news sites; and blogs hosted by blogger.com, livejournal.com, and wordpress.com. The payload modifies the Layered Service Provider (LSP) […]

Zbot Desperately Seeking AIM Users

by

The Zbot keylogger campaign-of-the-month targets users of AOL Instant Messenger (AIM) with a message that claims to be an update notification for users of the instant messaging client application. Users unfortunate enough to click through the link in the email message to download what they think is something called “aimupdate_7.1.6.475.exe” will be in for a rude awakening. The malicious page delivers its payload whether or not a victim clicks the link to get executable file: It opens an iframe to a site that attempts to use vulnerable versions of Adobe Reader to push the Zbot keylogger down to the victim’s […]

Phishers Break WoW’s Magic Spell Over Gamers

by

By Curtis Fechner and Andrew Brandt While we’ve touched on the subject of World of Warcraft phishers (and the Trojans they attempt to spread) a handful of times in the past several months, it’s worth mentioning the ongoing problems phishing posts cause both players and Blizzard, the game’s operator. To recap, the official message board for World of Warcraft is under constant attack by phishers, who use stolen credentials to post message board articles containing malicious links under the names of the innocent players whose passwords have been stolen. The links, which can be tied to virtually any kind of […]

Spammers Pushing Rogues Infiltrate Google Groups

by

Spammers hawking “fun videos” have been worming their way into Google Groups, the global message board Google built on the skeleton of the old Usenet network. Only, the pages the spammers point victims to, which don’t actually contain videos, come with a nasty surprise: Rogue antivirus apps. The attacks began late last year, but have been increasing in frequency through the holidays, and haven’t abated in the new year. The users sending out the spam messages all use free Gmail accounts (one even named his spam account Santa Claus), and have been requesting access to both open-membership and closed-membership Groups, […]

Ron Paul, Beyonce Tease a Drive-By Rogue AV

by

Here’s a mind-bender for you to ponder over the holidays: What do diva musician Beyonce, the massively-multiplayer game World of Warcraft, the anime series Naruto, and Libertarian politician (and failed presidential candidate) Ron Paul have in common? I couldn’t guess what you might come up with, but we’ve found a drive-by download attack that delivers malware, using these disparate icons as a hook to convince Web surfers to click malicious links. The hack attempt was discovered by a Threat Research Analyst who also happens to be a Ron Paul fanatic (and I do mean fanatic — that’s a photo of […]
