Relying on tens of thousands of fake “Your transaction is completed” emails, cybercriminals have just launched yet another malicious spam campaign attempting to socially engineer Bank of America’s (BofA) customers into executing a malicious attachment. Once unsuspecting users do so, their PCs automatically join the botnet operated by the cybercriminal/gang of cybercriminals operating it, leading to a successful compromise of their hosts.
Over the past couple of days, cybercriminals have launched two consecutive malware campaigns impersonating DHL in an attempt to trick users into thinking that they’ve received a parcel delivery notification. The first campaign comes with a malicious attachment, whereas in the second, the actual malicious archive is located on a compromised domain.
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.
Let’s profile the campaigns that took place last week, with the idea to assist in the ongoing attack attribution process.
Pitched by its author as a Remote Access Tool, the DIY (do it yourself) malware that I’ll profile in this post is currently cracked, and available for both novice, and experienced cybercriminals to take advantage of at selected cybercrime-friendly communities.
Cybercriminals are currently spamvertising tens of thousands of emails impersonating American Airlines in an attempt to trick its customers into thinking that they’ve received a download link for their E-ticket. Once they download and execute the malicious attachment, their PCs automatically join the botnet operated by the cybercriminal/gang of cybercriminals behind the campaign.
Cybercriminals are currently mass mailing tens of thousands of emails, in an attempt to trick users into thinking that the order for their “air transportation services has been accepted and processed”. In reality though, once users execute the malicious attachments, their PCs will automatically become part of the botnet managed by the malicious actors.
In a diversified underground marketplace, where multiple market players interact with one another on a daily basis, there are the “me too” developers, and the true “innovators” whose releases have the potential to cause widespread damage, ultimately resulting in huge financial losses internationally.
In this post, I’ll profile one such underground market release known as as “Zerokit, 0kit or the ring0 bundle” bootkit which was originally advertised at a popular invite-only/vetted cybercrime-friendly community back in 2011. I’ll emphasize on its core features, offer an inside peek into its administration panel, and discuss the novel “licensing” scheme used by its author, namely, to offer access to the bootkit in exchange for tens of thousands of malware-infected hosts on a monthly basis.
Over the past few days, we intercepted a malware campaign that spreads through Skype messages, exclusively coming from malware-infected friends or colleagues. Once users click on the shortened link, they’ll be exposed to a simple file download box, with the cybercriminals behind the campaign directly linking to the malicious executable.
We have recently intercepted a malicious spam campaign, that’s attempting to trick users into thinking that they’ve received a non-existent “changelog.” Once gullible and socially engineered users execute the malicious attachment, their PCs automatically become part of the botnet operated by the cybercriminal/gang of cybercriminals.
While the authors/support teams of some of the market leading Web malware exploitation kits are competing on their way to be the first kit to introduce a new exploit on a mass scale, others, largely influenced by the re-emergence of the DIY (do-it-yourself) trend across the cybercrime ecosystem, continue relying on good old fashioned social engineering attacks.
