Cover Your Assets on Data Privacy Day

by

Today is Data Privacy Day, which is supposed to remind us all that keeping our digital secrets a secret is important and necessary. To commemorate the event, I’d like to run down some of the most serious privacy threats any of us could face on a daily basis: How a malware infection puts your privacy at risk. For years, it’s been clear that the creators and distributors of malicious software are after one thing above all others — money. Whether they steal it (by installing a keylogger, or just phishing) or defraud you out of it (by coercing users to […]

Friends, Followers, Fans: Be On Guard in 2010

by

By Mike Kronenberg Do you use a social networking site? Be prepared, because I predict in 2010 it’ll be a major target for cyber criminals. Among the threat experts here at Webroot, we’ve discussed the ROI opportunity that social networks present an enterprising hacker who strings together the personal information people choose to share on social networks, or who creates a program to infect PCs with one click of a malicious link. I’ve also discussed the issue with my colleagues in the security industry. Each of us acknowledges that users of all kinds – be it individuals, public figures, nonprofits, […]

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 […]

New Koobface Creates its Own Malicious Web Pages

by

Over the past several months, we’ve seen Koobface steadily progress in its ability to infect systems with malware. In our latest tests, we’ve found that the most recent version of this social-networm has a few new holiday-themed tricks up its sleeve. Among those tricks are a new, improved “captcha breaker” utility; A tool to check whether you have a Google and/or a Blogspot account (and, if not,  it creates a new Google account); And a tool designed to create Google Reader pages on the fly, which the worm then uses to post malicious code. Those Google Reader accounts then end […]

Facebook Phishing Campaign Wants Your Passwords

by

Yet another new phishing campaign targeting users of Facebook struck over the Halloween holiday weekend. After scammers began filling inboxes last week with bogus “Facebook update” attachments, this weekend we saw a different group at work. Employing URLs with random domain names registered under the .eu top-level domain, the campaign looks similar to messages distributed in a recent series of phishing campaigns that attempt to convince the user that the mail comes from a legitimate source, such as the FDIC, IRS, HMRC (the UK’s tax authority), your IT department, or any of several well-known banks. The email messages, which use a […]

“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 […]

‘Koobfox’ variant digs for Firefox cookies

by

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 tool designed to steal credentials saved by Firefox (in the form of cookies and stored passwords). Users of the Firefox browser were, until now, able to thwart the pernicious spy’s ability to hijack a victim’s social network accounts, because the two browsers store their cookies in different locations, […]
