Tax-Season Malware Campaign Delivers Trojan Via Email

A new example of a long-term phenomenon delivers a banking trojan via a downloader activated by a URL in a phishing email.

The panicked frenzy of tax season's end has long carried with it an uptick in fraud and theft. This year is no different, with fraud activity rising in both quantity and sophistication after April 17.

In an interesting example of this year's campaigns, North Americans were targeted with the banking trojan known as URSNIF. Rather than being delivered as an attachment to a phishing email, the trojan came via a VBScript downloader that brought a .ZIP file, all launched by a click on a specific URL.

According to researchers at Trend Micro, the URL was part of a phishing email that mentioned possible tax problems and invited the recipient to click on the URL for more details. Once clicked, a page opened that looked like a legitimate tax information site. Buried in the code for the site, though, was obfuscated code for the VBScript downloader, which pointed to one of more than 100 URLs under 20 or more domains.

The researchers recommend spam filters, implementing proper policy management, and maximizing email security mechanisms as possible mitigations for the attack.
