Zbot Desperately Seeking AIM Users

by

The Zbot keylogger campaign-of-the-month targets users of AOL Instant Messenger (AIM) with a message that claims to be an update notification for users of the instant messaging client application. Users unfortunate enough to click through the link in the email message to download what they think is something called “aimupdate_7.1.6.475.exe” will be in for a rude awakening. The malicious page delivers its payload whether or not a victim clicks the link to get executable file: It opens an iframe to a site that attempts to use vulnerable versions of Adobe Reader to push the Zbot keylogger down to the victim’s […]

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 […]

Lazy Phishers Just Email the Phishing Web Page to You, Now

by

It was a particularly busy weekend for spammers, especially the creepy, evil ones who are trying to steal information (as opposed to the merely scungy pill vendors and their ilk). Webroot’s Threat Research team has recently seen a glut of phishing messages which, like most, purport to come from banks and ask you to update your account information. But unlike most phishing messages, which contain a link to a Web site, these phishing messages include an attached HTML file which, in essence, puts the phishing page right on your hard drive. When launched, the HTML file renders a sparse but effective phishing form […]

Outlook “Patch” Spam Leads to Keyloggers

by

Hot on the heels of the spam campaigns involving emails which purport to come from the IRS, HMRC, and from your IT department comes another round of fake “notification” spam emails — this time, warning users to download and install a patch for the Outlook and Outlook Express email clients. Like the previous rounds, the file a victim is prompted to download and (hopefully, won’t) install is the prolific, widely-disseminated keylogger we call Progdav (aka “Zbot”). The faux Web page which hosts the malicious file is dressed up to look like a Microsoft Update page, titled “Update for Microsoft Outlook […]

IRS Tax “Warning” Fraud Crosses the Pond, Targets the UK

by

For several months, we’ve been seeing spam and phishing Web sites which purport to be IRS notifications of delinquent non-payment of income taxes. Who can blame the fraudsters — almost no three letter agency of the US government inspires more dread and fear than good old Internal Revenue. In the UK, the counterpart to the IRS is called Her Majesty’s Revenue & Customs (or HMRC), even though it is the British government, and not the Queen’s Coldstream Guards, who dutifully stick a fork in the populace to pay up. The income tax filing deadline in the UK (for people who […]

“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 […]
