10 Threats from 2010 We’d Prefer Remain History

January 1, 2011 – 3:32 pm

By Andrew Brandt With 2010 finally behind us, and an unknown number of cyberattacks likely to come in the new year, I thought I’d run down a brief list of the malicious campaigns criminals pulled off last year that I’d really dread to see anyone repeat. Now that they’re in the past, they should stay [...]

Fake Firefox Update is a Social Engineering Triple Fail

December 21, 2010 – 4:49 pm

By Andrew Brandt Where’s the work ethic, malware geniuses? If this latest example of shenanigans is the best you can deliver, you’re not even trying to generate convincing scams — or even something that makes sense — anymore. One of our Threat Research Analysts pointed me to a Web page hosting a fake update program [...]

Search Hijacker Adds Files to Firefox Profile

November 5, 2010 – 11:49 am

By Andrew Brandt In September, I posted an item about a dropper which we call Trojan-Dropper-Headshot. This malware delivers everything including the kitchen sink when it infects your system. It has an absolute ton of payloads, any of which on their own constitute a serious problem. All together, they’re a nightmare. Among the payloads, we’ve [...]

Patchy Phisher Forces Firefox to Forego Forgetting Passwords

October 6, 2010 – 3:47 pm

By Andrew Brandt Every browser can, at the user’s discretion, be set up to remember passwords. In general, Webroot advises most users not to set the browser to store login credentials, because they’re so easily extracted by password-stealing Trojans like Zbot. In Firefox, for example, you can click Tools, Options, then open the Security tab, [...]

‘Koobfox’ variant digs for Firefox cookies

September 3, 2009 – 3:34 pm

By Andrew Brandt A new variant of the Koobface worm started striking out this week, with a twist: Where the older Koobface would steal and use the cookies saved by Internet Explorer which store social network logins in order to spread its infectious messages in the victim’s name, this new variant is pulling down a [...]

Adware Purveyors Panning for Search Gold

March 27, 2009 – 2:30 pm

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 [...]

New Malware Ruins Firefox

March 25, 2009 – 3:10 am

By Andrew Brandt 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: [...]
