Cybercriminals have recently launched yet another massive spam campaign attempting to trick users into clicking on malicious links or executing malicious attachments found in the spamvertised emails.

Sticking to their well proven practice of systematically rotating impersonated brands, the cybercriminals behind a huge majority of the malicious campaigns that we’ve been profiling recently are once again impersonating Intuit in an attempt to trick its customers into clicking on links exposing them to the client-side exploits served by the Black Hole Exploit Kit.

Cybercriminals are mass mailing malicious emails about a meeting you wouldn’t want to attend – unless you want to compromise the integrity of your computer.
Once executed, the malicious attachment opens a backdoor on the affected host, allowing the cybercriminals behind the campaign to gain complete access to the affected host. Naturally, we’ve been monitoring their operations for quite some time, and are easily able to identify multiple connections between their previously launched campaigns.

Cybercriminals are currently impersonating T-Mobile U.K, in an attempt to trick its customers into downloading a bogus billing information report. Upon execution, the malware opens a backdoor on the affected host, allowing the cybercriminals behind the campaign complete access to the infected PC.

Over the past couple of days, cybercriminals have launched yet another massive spam campaign, once again targeting U.K users. This time, they are impersonating Vodafone U.K, in an attempt to trick its customers into executing a bogus MMS attachment found in the malicious emails. Upon execution, the sample opens a backdoor on the affected hosts, allowing the cybercriminals behind the campaign complete access to the affected PC.

From UPS, USPS to DHL, bogus and malicious parcel tracking confirmations are a common social engineering technique often used by cybercriminals to trick users into clicking on malicious links or executing malicious attachments found in the spamvertised emails.
Continuing what appears to be a working social engineering tactic, cybercriminals are currently mass mailing bogus DHL ‘Express Delivery Notifications’ in an attempt to trick users into executing the malicious attachment. Once executed, it opens a backdoor on the affected host allowing the cybercriminals behind the campaign complete access to the infected PC.

Facebook users, watch out!
A recently launched malicious spam campaign is impersonating Facebook, Inc. in an attempt to trick its one billion users into thinking that they’ve received a notification alerting them on activities they may have missed on Facebook. Upon clicking on any of the links found in the email, users are exposed to the client-side exploits served by the Black Hole Exploit Kit.

Over the past few weeks, cybercriminals have been persistently spamvertising ‘Inter-company invoice’ themed emails, in an attempt to trick users into viewing the malicious .html attachment, or unpack and execute the malicious binary found in the attached archives. Upon clicking on the link, users are exposed to the client-side exploits served by the latest version of the Black Hole Exploit Kit.

What would an attacker do if they were attempting to inject malicious iFrames on as many Web sites as possible? Would they rely on search engines’ reconnaissance as a foundation fo their efficient exploitation process, data mine a botnet’s infected population for accounting data related to CPanel, FTP and SSH accounts, purchase access to botnet logs, unethically pen-test a Web property’s infrastructure, or hit the jackpot with an ingenious idea that’s been trending as of recently within the cybercrime ecosystem? No, they wouldn’t rely on any of these. They would just seek access to servers hosting as many domains as possible and efficiently embed malicious iFrames on each and every .php/.html/.js found within these domains. At least that’s what the cybercriminal operations that I’ll elaborate on in this post are all about. Let’s take a peek at a recently advertised DIY mass iFrame injecting Apache 2.x module that appears to have already been responsible for a variety of security incidents across the globe.
This module makes it virtually impossible for a webmaster to remove the infection from their Web site, affects millions of users in the process, and earns thousands of dollars for the cybercriminals operating it. More details: (more…)
