It seems as though every few weeks we see a new encrypting ransomware variant. It’s not surprising either since the business model of ransoming files for money is tried and true. Whether it’s important work documents, treasured wedding pictures, or complete discographies of your favorite artists, everyone has valuable data they don’t want taken. This is the last thing anyone wants to see. This variant does bring some new features to the scene, but also fails at other lessons learnt by previous variants. Starting with the new features this variant will now just “delete” the files after encrypting them (it just […]

Sony had a rough weekend. And not just Sony; last weekend wasn’t the best time to be a gamer. Here’s the skinny… Early yesterday morning, Sony’s PlayStation Network (PSN for short) was hit with a massive Distributed Denial of Service (DDoS) attack, causing it to crash temporarily and hamper online play for many PlayStation gamers. (Source: Google Images) Sony Online Entertainment President John Smedley quickly took to Twitter to let users know about the attack before tweeting that he’d be offline for three hours as he flew back to San Diego from Dallas on AA Flight #362. Well, not long […]
Yesterday, the New York Times published an exclusive story on what many are stating to be the largest series of hacks ever, all revealed by Hold Security in their latest report. With a report of over 1.2 billion unique username-password combinations and over 500 million e-mail addressed amassed by a Russian hacker group dubbed CyberVol (vol is Russian for thief). While the reactions among the security industry are mixed, with some researchers raising a few questions of the masterwork behind the hack, the story does bring to the public’s attention the necessity of strong, personal, online security policies for all […]
Recently in the news the FBI filed a status report updating on the court-authorized measures to neutralize GameOver Zeus and Cryptolocker. While the report states that “all or nearly all” of the active computers infected with GameOver Zeus have been liberated from the criminals’ control, they also stated that Cryptolocker is “effectively non-functional and unable to encrypt newly infected computers.” Their reasoning for this is that Cryptolocker has been neutralized by the disruption and cannot communicate with the command and control servers to receive instructions or send RSA keys after encryption.

Relying on the systematic release of DIY (do-it-yourself) mobile malware generating tools, commercial availability of mobile malware releases intersecting with the efficient exploitation of legitimate Web sites through fraudulent underground traffic exchanges, as well as the utilization of cybercrime-friendly affiliate based revenue sharing schemes, cybercriminals continue capitalizing on the ever-growing Android mobile market segment for the purpose of achieving a positive ROI (return on investment) for their fraudulent activities. We’ve recently spotted yet another underground market proposition offering access to Android-based infected devices. Let’s take a peek inside its Web-based command and control interface, discuss its features, as well as the proposition’s relevance […]
Cybercriminals continue to efficiently populate their botnets, through the systematic and persistent spamvertising of tens of thousands of fake emails, for the purpose of socially engineering gullible end users into executing the malicious attachments found in the rogue emails. We’ve recently intercepted a currently circulating malicious campaign, impersonating Barkeley Futures Limited, tricking users into thinking that they’ve received a legitimate “Customer Daily Statement”.
Cybercriminals continue spamvertising tens of thousands of malicious emails on their way to socially engineer gullible end users, ultimately increasing their botnet’s infected population through the systematic and persistent rotation of popular brands. We’ve recently intercepted a currently circulating malicious campaign enticing users into executing the fake attachment. More details:
Despite the prevalence of Web based client-side exploitation tools as the cybercrime ecosystem’s primary infection vector, in a series of blog posts, we’ve been emphasizing on the emergence of managed/hosted/DIY malicious Java applet generating tools/platforms, highlighting the existence of a growing market segment relying on ‘visual social engineering’ vectors for the purpose of tricking end users into executing malicious/rogue/fake Java applets, ultimately joining a cybercriminal’s botnet. We’ve recently spotted yet another Web based Java drive-by generating tool, and decided to take a peek inside the malicious infrastructure supporting it.
In a cybercrime ecosystem dominated by DIY (do-it-yourself) malware/botnet generating releases, populating multiple market segments on a systematic basis, cybercriminals continue seeking new ways to acquire and efficiently monetize fraudulently obtained accounting data, for the purpose of achieving a positive ROI (Return on Investment) on their fraudulent operations. In a series of blog posts, we’ve been detailing the existence of commercially available server-based malicious script/iframe injecting/embedding releases/platforms utilizing legitimate infrastructure for the purpose of hijacking legitimate traffic, ultimately infecting tens of thousands of legitimate users. We’ve recently spotted a long-run Web-based managed malicious/iframe injecting/embedding service relying on compromised accounting data for legitimate traffic acquisition […]
Cybercriminals continue diversifying their portfolios of standardized fraudulent services, in an attempt to efficiently monetize their malicious ‘know-how’, further contributing to the growth of the cybercrime ecosystem. In a series of blog posts highlighting the emergence of the boutique cybercrime-friendly E-shops, we’ve been emphasizing on the over-supply of compromised/stolen accounting data, efficiently aggregated through the TTPs (tactics, techniques and procedures) described in our “Cybercrime Trends – 2013” observations. We’ve recently spotted a newly launched all-in-one cybercrime-friendly E-shop, offering a diversified portfolio of managed/DIY services/products, exposing a malicious infrastructure worth keeping an eye on. Let’s take a peek inside the E-shop’s inventory […]
