Zeus Infection Spoofing Bitdefender AV

by

Over the Christmas period, we here at Webroot  have noticed a large amount of Zeus infections that are spoofing the Bitdefender name. While infections spoofing AV companies aren’t unusual, it’s been a while since we have seen such a spike on one particular vendor in such a short time period. Most of the names are slight variations, but the numbers are impressive – Overall, we have seen 40,000 unique MD5`s in the last week alone! The infection being dropped is from the Zeus family of infections, which are banking Trojans designed to steal login information when the user logs into […]

New IRC/HTTP based DDoS bot wipes out competing malware

by

Everyday, new vendors offering malicious software enter the underground marketplace. And although many will fail to differentiate their underground market proposition in market crowded with reputable, trusted and verified sellers, others will quickly build their reputation on the basis of their “innovative” work, potentially stealing some market share and becoming rich by offering the tools necessary to facilitate cybercrime. Publicly announced in late 2012, the IRC/HTTP based DDoS bot that I’ll profile in this post has been under constant development. From its initial IRC-based version, the bot has evolved into a HTTP-based one, supporting 10 different DDoS attack techniques as well as possessing a […]

New ZeuS source code based rootkit available for purchase on the underground market

by

By Dancho Danchev We have recently spotted a new underground market ad, featuring a new commercially available malware bot+rootkit based on the ZeuS crimeware’s leaked source code. According to its author, the modular nature of the bot, allows him to keep coming up with new plugins, resulting in systematic “innovation” and the introduction of new features. What’s the long-term potential of this malware bot with rootkit functionality? Does it have the capacity to challenge the market leading malware bot families? What are some of the features that differentiate it from the rest of competing bots currently in the wild? What’s the price of the […]

Outdated Operating System? This BlackHole Exploit Kit has you in its sights

by

By Mike Johnson Several weeks back, I was presented with a group of snapshots from an active BlackHole Exploit Kit 1.2 Control Panel. As with other toolkits I’ve seen in the wild, this one has all the makings of some real bad medicine. The authors have yet again gone to the trouble of making this toolkit incredibly easy to use and widely available for a price. Just a little unsavory web hosting in a country with few or no diplomatic relations and off to the races they go. It appears this toolkit is configurable in both Russian and English, making one wonder its true origins. I’ve […]

A look inside the SpyEye Trojan admin console

by

By Michael Johnson At Webroot we’ve been researching and chronicling developments with SpyEye since we first saw it in April 2010. This nasty Trojan is the successor to the Zeus Trojan, and it became essentially the main rootkit available for sale after the author of ZeuS left the underground market and sold ZeuS sources to the SpyEye team. Over the last six months, through Webroot’s real-time watch technology and through my own adventures hunting malware proactively in my spare time, I’ve noticed an extreme escalation of SpyEye infections. Last week I came across a URL for a password-protected site and […]

Phishers Want You to Have a Coke and a Drive-by

by

As recently as a few months ago, malware distributors went to what looked like great lengths to craft complex, sophisticated Web pages designed to trick visitors into believing they were visiting a page with an embedded video and — oops! — you need to update your copy of Adobe Flash in order to view it. Well, those days of hard work seem to have faded into memory. All we’re left now is this. In a recent attack that came to my attention, the guys behind the attack didn’t bother to build a sophisticated Web page. Well, nothing along the lines […]

Keylogger Poses as Document from Spain’s Central Bank

by

An attempt to push down the Trojan-Backdoor-Zbot password thief to Spaniards may signal a new wave of attacks by a crew of attackers who spent the better part of 2009 trying to convince gullible Internet users in different countries to download and execute Zbot installers poorly disguised as transaction records or other important financial documents. A bogus Banco de España (BdE) Web site came and went quickly last week, but not before we took a deep dive and came up with a mouthful of malware. Believe me, it tasted terrible. The page, designed to mimic closely the appearance of the […]

“Shipping Confirmation” Malware on the Rise

by

As autumn approaches, the world typically sees an increase in the number of online shopping trips, as people take advantage of bargains from late-year sales, and prepare for various holidays. And, right on cue, we’re also seeing an increase in the number of Trojans distributed in the guise of “shipping confirmation” email messages. And these Trojans are packing a triple threat of backdoors designed to steal logins and take command of infected PCs. The Trojan arrives attached to a vaguely-worded email message thanking the recipient for their order of a high-ticket item. Previous versions of this same kind of message […]
