In reality, once users execute the malicious attachment, it will download and drop additional malware on the affected hosts, giving the cybercriminals behind the campaign complete access to the affected host.

Cybercriminals are currently spamvertising tens of thousands of bogus emails impersonating New York State’s Department of Motor Vehicles (DMV) in an attempt to trick users into thinking they’ve received an uniform traffic ticket, that they should open, print and send to their town’s court.
In reality, once users open and execute the malicious attachment, their PCs will automatically join the botnet operated by the cybercriminal/cybercriminals behind the campaign.

Following the recent events, opportunistic cybercriminals have been spamvertising tens of thousands of malicious emails in an attempt to capitalize on on the latest breaking news.
We’re currently aware of two “Boston marathon explosion” themed campaigns that took place last week, one of which is impersonating CNN, and another is using the “fertilizer plant exposion in Texas” theme, both of which redirect to either the RedKit or the market leading Black Hole Exploit Kit.

Just how challenged are cybercriminals when they’re being exposed to CAPTCHAs in 2013?
Not even bothering to “solve the problem” by themselves anymore, thanks to the cost-efficient, effective, and fully working process of outsourcing the CAPTCHA solving process to humans thereby allowing the cybercriminals to abuse any given Web property, as if it were multiple humans actually performing the actions.

Earlier this year we profiled a newly released mobile/phone number harvesting application, a common tool in the arsenal of mobile spammers, as well as vendors of mobile spam services. Since the practice is an inseparable part of the mobile spamming process, cybercriminals continue periodically releasing new mobile number harvesting applications, update their features, but most interestingly, continue exclusively targeting Russian users.
In this post, I’ll profile yet another DIY mobile number harvesting tool available on the underground marketplace since 2011, and emphasize on its most recent (2013) updated feature, namely, the use of proxies.
