Its tax season and cybercriminals are mass mailing tens of thousands of IRS (Internal Revenue Service) themed emails in an attempt to trick users into thinking that their income tax refund has been “turned down”. Once users click on any of the links found in the malicious emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
In March 2012, we intercepted an IRS themed malicious campaign that was serving client-side exploits to prospective victims in an attempt to drop malware on the affected hosts.
This week, we intercepted three consecutive campaigns using the exact same email template used in the March campaign. What has changed? Are the cybercriminals behind these campaigns relying on any new tactics, or are they basically sticking to well proven techniques to infect tens of thousands of socially engineered users?
Over the past 24 hours, the cybercriminals behind the campaign resumed mass mailing of the same IRS email template, exposing millions of users to the threats posed by the social engineering driven campaign.
Recently, cybercriminals launched yet another massive spam campaign, this time impersonating the Internal Revenue Service (IRS) in an attempt to trick tax payers into clicking on a link pointing to a bogus Microsoft Word Document. Once the user clicks on it, they are redirected to a Black Hole exploit kit landing URL, where they’re exposed to the client-side exploits served by the kit.
Getting ready to file your taxes online — and doing it at the last minute? Well, cyber-scammers are ready for you. Thieves are schemers, and they’ve got a bag full of tricks to steal your identity. You might even be doing things to make their job easier. And if you use a PC at work to do your return, identity theft could be as simple as a crook (or an unscrupulous coworker) digging around and finding sensitive files.
One might send you an e-mail that offers a quick refund — or a warning about a problem with your already-filed tax return. Maybe they’ll pitch you with an expert’s review of your tax return, or helpfully offer advice, asking for all the sensitive financial details you’d normally put on your return so they can “look up your account.”
Here are eight tips to stay one step ahead of these virtual pickpockets and protect yourself.
