New DIY RDP-based botnet generating tool leaks in the wild
In times when we’re witnessing the most prolific and systematic abuse of the Internet for fraudulent and purely malicious activities, there are still people who cannot fully grasp the essence of the cybercrime ecosystem in the context of the big picture — economic terrosm — and in fact often deny its existence, describing it as anything else but an underdeveloped sellers/buyers market.
That’s totally wrong.
In this post, I’ll discuss the cybercrime ecosystem events that eventually led to the leakage of a private DIY botnet building and managing platform – with the idea to raise more awareness on the dynamics taking place within the vibrant ecosystem.

‘Terminated Wire Transfer Notification/ACH File ID” themed malicious campaigns lead to Black Hole Exploit Kit
A couple of days ago our sensors picked up two separate malicious email campaigns, both impersonating Data Processing Services, that upon successful client-side exploitation (courtesy of the Black Hole Exploit Kit), drops an identical piece of malicious software.
Let’s dissect the campaigns, expose the malicious domains portfolio, connect them to previously profiled malicious campaigns, and analyze the behavior of the dropped malware.

‘ADP Payroll Invoice’ themed emails lead to malware
Over the past week, we intercepted a massive ‘ADP Payroll Invoice” themed malicious spam campaign, enticing users into executing a malicious file attachment.

Spotted: cybercriminals working on new Western Union based ‘money mule management’ script
Risk-forwarding is an inseparable part of the cybercrime ecosystem.
Whether it’s the use of malware-infected hosts as stepping-stones, the issuing of License Agreements for your latest rootkit release stating that it’s meant to be tested against the customer’s own systems — you wish — or the selling of cheap access to verified PayPal accounts, in an attempt to mitigate the “cash-out” risk by forwarding it to a more experienced cybercriminal, the process of risk-forwarding is visible across the entire ecosystem.
In this post I’ll discuss a recently spotted Wetern Union based money mule management script. While the cybercriminals are currently developing this script, it is evidence of a cybercrime ecosystem trend focusing on the efficiency-centered standardization mentality of sophisticated cybercriminals.

Hacked PCs as ‘anonymization stepping-stones’ service operates in the open since 2004
By Dancho Danchev
On the majority of occasions, cybercriminals will take basic OPSEC (Operational Security) precautions when using the Internet, in an attempt to make it harder for law enforcement to keep track of their fraudulent activities. Over the years, these techniques have greatly evolved to include hybrid online anonymity solutions offered exclusively to cybercriminals internationally.
In this post, I’ll profile a cybercrime-friendly service that’s been offering hacked PCs to be converted into “anonymization stepping-stones” since 2004.

Cybercrime-friendly community branded HTTP/SMTP based keylogger spotted in the wild
By Dancho Danchev
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.
