What are cybercrime-facilitating programmers up to when they’re not busy fulfilling custom orders? Releasing DIY (do-it-yourself) user-friendly tools allowing anyone an easy entry into the world of cybercrime, and securing their revenue streams thanks to the active advertisements of these tools across closed cybercrime-friendly Web communities.
In this post, I’ll profile a recently advertised DIY HTTP-based botnet tool, that allows virtually anyone to operate their own botnet.
Cybercriminals are currently attempting to trick Kindle owners into thinking that they’ve received a receipt from an E-book purchase from Amazon.com. In reality, when 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.
On a daily basis, we intercept hundreds of thousands of fraudulent or malicious emails whose purpose is to either infect users with malicious software or turn them into victims of fraudulent schemes. About 99% of these campaigns rely on social engineering tactics, and in the cases where they don’t include direct links to the actual malware, they direct users to the market leading Black Hole Exploit Kit.
In terms of volume and persistence, throughout January, 2013, a single malicious campaign impersonating FedExtopped our metrics data. What’s so special about this campaign? It’s the fact that the digital fingerprint of one of the most recently introduced malware variants used in the campaign corresponds to the digital fingerprint of a malware-serving campaign that we’ve already profiled, indicating that they’ve been launched by the same cybercriminal/gang of cybercriminals.
Cybercriminals are mass mailing tens of thousands of emails, impersonating Booking.com, in an attempt to trick its users into thinking that their credit card was not accepted. Users are then urged to click on a fake “Print Booking Details” link, which leads them to the malware used in the campaign.
In December, 2012, we intercepted a professional-looking email that was impersonating Facebook Inc. in an attempt to trick its users into thinking that they’ve received an “Account Cancellation Request“. In reality, once users clicked on the links, their hosts were automatically exploited through outdated and already patched client-side vulnerabilities, which dropped malware on the affected PCs.
Over the past 24 hours, cybercriminals have resumed spamvertising tens of thousands of legitimate-looking Facebook themed emails, once again using the same social engineering theme.
Users of FedEx’s Online Billing service, watch out!
Cybercriminals are currently mass mailing tens of thousands of emails impersonating the company, in an attempt to trick its customers into clicking on exploits and malware dropping links found in the legitimate-looking emails.
Financial institutions and online payment processors are a common target for cybercriminals, who systematically brand-jack and abuse the reputation of their trusted brands, in an attempt to scam or serve malware to their customers.
Over the past 24 hours, cybercriminals have launched yet another spam campaign, impersonating PayPal, in an attempt to trick its users into thinking that they’ve received a “Transaction Confirmation“, which in reality they never really made. Once users click on any of the links found in the malicious emails, they’re exposed to the client-side exploits served by the Black Hole Exploit Kit.
Over the past 24 hours, cybercriminals have launched yet another massive spam campaign, impersonating LinkedIn, in an attempt to trick its users into clicking on the malicious links found in the bogus “Invitation Notification” themed emails. Once they click on the links, users are automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.
Cybercriminals are currently spamvertising tens of thousands of fake emails, impersonating Intuit, in an attempt to trick its customers and users into clicking on the malicious links found in the emails.
Once users click on any of the links, they’re exposed to the client-side exploits served by the latest version of the Black Hole Exploit Kit, which ultimately drops malware on the affected hosts.
Over the past 24 hours, our sensor networks picked up an interesting website infection affecting a popular Bulgarian website for branded watches, which ultimately redirects and downloads premium rate SMS Android malware on the visiting user devices. The affected Bulgarian website is only the tip of the iceberg, based on the diversified portfolio of malicious domains known to have been launched by the same party that launched the original campaign.
