All forms of software that act with malicious intent

Over the past week, we intercepted a massive ‘ADP Payroll Invoice” themed malicious spam campaign, enticing users into executing a malicious file attachment. Once users execute the sample, it downloads additional pieces of malware on the affected host, compromising the integrity, and violating the confidentiality of the affected PC.

Cybercriminals are currently spamvertising tens of thousands of malicious emails impersonating BBC News, in an attempt to trick users into thinking that someone has shared a Cyprus bailout themed news item with them. Once users click on any of the links found in the fake emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.

Cybercriminals are currently mass mailing tens of thousands malicious ‘CNN Breaking News’ themed emails, in an attempt to trick users into clicking on the exploit-serving and malware-dropping links found within. Once users click on any of the links found in the bogus emails, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.

Utilizing basic site ‘stickiness’ and visitor retention practices, over the years, cybercrime-friendly communities have been vigorously competing to attract, satisfy, and retain their visitors. From exclusive services available only to community members, to DIY cybercrime-friendly tools, the practice is still a common way for the community administrators to boost the underground reputation of their forum.
However, there are certain communities that will use the underground reputation of their forum to boost their sales, by releasing private DIY cybercrime-friendly tools, and promoting them under the umbrella of the community brand.
In this post, I’ll profile a HTTP/SMTP-based keylogger that’s been commercially available to members of a cybercrime-friendly community since 2011.

A currently ongoing malicious email campaign is impersonating ADP in an attempt to trick its customers into thinking that they’ve received a ‘Package Delivery Notification.’ In reality though, once a user clicks on any of the links found in the malicious email, they’re automatically exposed to the client-side exploits served by the Black Hole Exploit Kit.

Over the last couple of days, a cybercricriminal/gang of cybercriminals that we’ve been extensively profiling, resumed spamvertising tens of thousands of emails, in an attempt to trick users that they have a pending wire transfer. 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 week, a cybercriminal/gang of cybercriminals whose activities we’ve been actively profiling over a significant period of time, launched two separate massive spam campaigns, this time impersonating the Better Business Bureau (BBB), in an attempt to trick users into thinking that their BBB accreditation has been terminated.
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.

Just as we anticipated on numerous occassions in our series of blog posts exploring the emerging DIY (do it yourself) trend within the cybercrime ecosystem, novice cybercriminals continue attempting to steal market share from market leaders, in order for them to either gain credibility within a particular cybercrime-friendly community, or secure a revenue stream.
Throughout 2012, we’ve witnessed the emergence of both, publicly obtainable, and commercially available, DIY unsigned Java applet generators. Largely relying on social engineering thanks to their built-in feature allowing them to “clone” any given Web site, these tools remain a popular attack vector in the arsenal of the less sophisticated cybercriminal, looking for ways to build his very own botnet.
In this post, I’ll profile one of the most recently released DIY tools.

Yesterday, a relatively unknown group of cybercriminals publicly announced the availability of a new Web malware exploitation kit. What’s so special about it is the fact that its current version is entirely based on Java exploits (CVE-2012-1723 and CVE-2013-0431), naturally, with “more exploits to be introduced any time soon”.
Let’s take a peek at the statistics and infection rates produced by this kit, as well as discuss its potential, or lack thereof, to cause widespread damage to endpoints internationally.
