WoW Expansion Beta Likely to Spawn Phishers, Scams

by

Blizzard’s announcement today that they will begin a closed beta-test for the latest expansion pack is likely to generate a lot of excitement among that particularly low breed of online criminals who steal the fruits of other people’s entertainment when they commandeer passwords for other players. While it’s hard to believe that most players of online games aren’t aware of the profusion of phishing sites attempting to steal logins, the problem clearly isn’t going away, so the warnings remain the same: Keep a close eye on your browser’s Address Bar, and make sure you’re really logging into Blizzard’s Web site, […]

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 […]

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┬ásites 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.

One Click, and the Exploit Kit’s Got You

by

After all the brouhaha surrounding the NYTimes.com website hosting ads which spawned rogue antivirus Fakealerts last weekend, I spent a considerable amount of time looking at so-called exploit kits this week. These are packages, made up of custom made Web pages (typically coded in the PHP scripting language), which perform a linchpin activity for malware distributors. Namely, they deliver the infection to the victim, using the most effective methods, based on parameters which help identify particular vulnerabilities in the victim’s browser, operating system, or applications. There’s no indication that an exploit kit was used by the attackers in the NYTimes.com […]

Jackson/Fawcett Malware is Extortion-ware

by

As I reported yesterday, searches for information about the deaths of Michael Jackson or Farrah Fawcett were turning up links to malware. This came as no surprise to anyone, though the speed with which the links spread was astonishing: Within minutes of the first confirmation that Jackson had succumbed to a heart attack, the first malicious blog posts began popping up in search results. We’re continuing to monitor hundreds of malicious sites touting news of Jackson’s demise — and new malicious blogs are coming up as fast as the blog services can shut them off. The first site we encountered […]

Adware Purveyors Panning for Search Gold

by

We know most adware companies are shameless in their pursuit of revenue, but it’s been a while since we’ve seen anything as bizarre (or hilariously bold) as the sales pitch from a relative neophyte to the world of adware, which calls itself SnappyAds. On its homepage, SnappyAds posits the hypothetical glee of two business-suited online ad men counting the thousands of dollars they’ve allegedly earned from their allegedly lucrative venture. Behind the SnappyAds facade, however, is an adware client we (and a few other AV companies) call SearchPan. The installer for the adware client application is hosted on SnappyAds’ webserver, […]

New Malware Ruins Firefox

by

Late last year, we read all the buzz about ChromeInject, a malicious DLL that was being billed as the first malware specifically targeting Firefox. It was interesting to see that someone built a phishing Trojan for a different browser platform, but ChromeInject was also clearly an early phase in Firefox malware development: It was fairly obvious, and it was easy to eliminate, because it generated an entry in the Plugins menu called “Basic Example Plugin for Mozilla” which you could simply disable with a single mouse click. Well now it looks like the bar’s been raised. In the past few […]
