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: read more…
A currently ongoing spam campaign attempts to trick users into thinking that their ability to send Domestic Wire Transfers has been disabled. Impersonating the Federal Deposit Insurance Corporation (FDIC), the cybercriminals behind the campaign are potentially earning thousands of dollars in the process of monetizing the anticipated traffic.
Once users click on the bogus ‘secure download link’, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.

Cybercriminals have resumed spamvertising the Intuit Direct Deposit Service Informer themed malicious emails, which we intercepted and profiled earlier this month. While using an identical email template, the cybercriminals behind the campaign have introduced new client-side exploits serving domains, which ultimately lead to the latest version of the Black Hole Exploit Kit.

Cybercriminals are currently mass mailing millions of emails impersonating Microsoft Corporation in an attempt to trick users into clicking on a link in a bogus ‘License Order” confirmation email. Upon clicking on the link, users are exposed to the client-side exploits served by the latest version of the Black Hole Exploit Kit.

Attempting to achieve a higher click-through rate for their exploits and malware serving malicious campaign, cybercriminals are currently spamvertising millions of emails attempting to trick users into thinking they’ve become part of a private conversation about missing EPLI policies.
In reality, clicking on any of the links in the oddly formulated email will expose them to the client-side exploits served by the latest version of 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?
Let’s find out.

Cybercriminals are currently mass mailing millions of emails trying to trick recipients into executing malicious attachments pitched as recently arrived fax messages. Upon running the malicious executables, users are exposed to a variety of dropped malware variants in a clear attempt by the cybercriminals to add additional layers of monetization to the campaign.

Cybercriminals are currently spamvertising millions of emails impersonating the Better Business Bureau (BBB), in an attempt to trick users into clicking on a link to a non-existent report. Upon clicking on the link, users are exposed to the client-side exploits served by the latest version of the Black Hole Exploit Kit.

A cybercriminal/group of cybercriminals that’s been responsible for a series of malware attacks that I’ve been recently profiling, continues to systematically rotate the impersonated brands and the actual malicious payload dropped by the market leading Black Hole Exploit Kit. The prospective target of their latest campaign? PayPal users.

Largely driven by a widespread adoption of growth and efficiency oriented strategies applied by cybercriminals within the entire spectrum of the cybercrime ecosystem, we’ve witnessed the emergence and development of the mobile device market segment over the past few years. Motivated by the fact that more people own a mobile device than a PC, cybercriminals quickly adapted and started innovating in an attempt to capitalize on this ever-growing market segment within their portfolio of fraudulent operations.
In this post I’ll profile a DIY Mail-to-SMS flooder that’s abusing a popular feature offered by international and U.S based mobile carriers – the ability to SMS any number through an email message. The DIY SMS flooder exclusively targets U.S users.
