Rogues Mug Big Bird on his Birthday

By Andrew Brandt

In a move sure to raise the ire of Sesame Street fans everywhere, the black hat SEO gangs that have been manipulating Google results for the better part of the year have seized on a new target from which they’ve launched their current salvo of rogue antivirus guano. That’s right, the lovable, giant [...]

Trojan Decodes Captchas Using Stolen Commercial Tools

By Andrew Brandt

A new Trojan quietly circulating in the wild uses components from a commercial optical character recognition (OCR) application to decode captchas, those jumbled-text images meant to help a website discern human activity from automated bots.
The OCR-using captcha breaking tool is just one component of the Trojan. Its main purpose appears to be to [...]

Rogues Impersonate Google, Firefox Security Alerts

By Andrew Brandt

In the past week, we’ve begun to see new fakealerts — those disturbingly effective, entirely bogus “virus warning” messages — that appear to impersonate the appearance and text of legitimate warning dialogs you might see while surfing with the Firefox browser, or searching Google. The dialog, in a stern, red dialog box on [...]

More Malware Trades on Tawdry Searches

By Andrew Brandt

By now, you’ve most likely heard about how an ESPN reporter was victimized, and that a surreptitiously recorded video was distributed online. You may also have read that malware distributors were taking advantage of the high level of interest in this video to rapidly disseminate malware by convincing people to click links to malicious [...]

AutoCAD Adware Trojans Target Techies

By Andrew Brandt

Every once in a while, you hear whispers or rumors about specially-crafted, targeted malware designed to steal a specific piece of data from a particular victim. The data thieves, in these limited cases, tend to be clever, thoughtful, and methodical in both the creation and deployment of their creations.
Rarely do malware researchers encounter [...]

Jackson/Fawcett Malware is Extortion-ware

By Andrew Brandt

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, [...]

Adware client tags you as its pitchman

By Andrew Brandt

Over the past week, someone has been spamming the file sharing site ThePirateBay.org with comments advertising a new “product” called BittorrentBooster. According to the site’s administrators, the spammer used a large number of fraudulently registered accounts to post the messages as feedback, attached to hundreds, possibly thousands, of downloadable .torrent files, which file-sharers [...]

April 2009 wrapup: Thumbdrives under threat

By Andrew Brandt

We’ve just tallied the top 10 threats Webroot’s consumer products detected during the month of April, and some interesting trends appear to be shaping up.
Conficker aside, the first quarter of 2009 seemed to be dominated by worms that spread not only over a network, but to virtually anything you can plug into a USB port to store [...]

Adware Purveyors Panning for Search Gold

By Andrew Brandt

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 [...]

Stepping up to the Loserbar

By Andrew Brandt

Last year, we at Webroot (as well as many other people) saw a huge spike in two specific types of malware: Rogue antispyware products — the ineffective, deceptive kind — and the various tricks the companies that sell rogues use to trick you into downloading (and eventually buying) their bogus products, something we [...]
