It’s that time of the year! The moment when we reflect back on the cybercrime tactics, techniques and procedures (TTPs) that shaped 2013, in order to constructively speculate on what’s to come for 2014 in terms of fraudulent and malicious campaigns, orchestrated by opportunistic cybercriminal adversaries across the globe. Throughout 2013, we continued to observe and profile TTPs, which were crucial for the success, profitability and growth of the cybercrime ecosystem internationally, such as, for instance, widespread proliferation of the campaigns, professionalism and the implementation of basic business/economic/marketing concepts, improved QA (Quality Assurance), vertical integration in an attempt to occupy […]

By Tyler Moffitt We see users on the internet getting infected with Rogue Security Malware all the time. In fact, it’s one of the most common and obvious type of infections we see. The Rogues lock-down your computer and prevent you from opening any applications so you’re forced to read their scam. Although they use various tactics and convincing GUIs to get onto your computer, they all share a common goal: To get your money.
By Dancho Danchev In 2013, you no longer need to posses sophisticated programming skills to manage a ransomware botnet, potentially tricking tens of thousands of gullible users, per day, into initiating a micro-payment to pay the ransom for having their PC locked down. You’ve got managed ransomware services doing it for you. In this post I’ll profile a recently spotted underground market proposition detailing the success story of a ransomware botnet master that’s been in business for over 4 years, claiming to be earning over five hundred thousands rubles per month. More details:
It’s that time of the year! The moment when we look back, and reflect on Webroot’s Threat Blog most popular content for 2012. Which are this year’s most popular posts? What distinguished them from the rest of the analyses published on a daily basis, throughout the entire year? Let’s find out.
Aiming to ensure that their malware doesn’t end up in the hands of vendors and researchers, cybercriminals are actively experimenting with different quality assurance processes whose objective is to increase the probability of their campaigns successfully propagating in the wild without detection. Some of these techniques include multiple offline antivirus scanning interfaces offering the cybercriminal a guarantee that their malicious program would remain undetected, before they launch their malicious campaign in the wild. In the wild since 2006, Kim’s Multiple Antivirus Scanner is still actively used among cybercriminals wanting to ensure that their malicious software is pre-scanned against the signature-based scanning techniques […]
The criminals who push rogues at the world don’t really care about the reputations of the ISPs or Web hosting services they abuse. They leap from free service to free service until they’ve thoroughly worn out their welcome and, in some cases, destroyed the reputation of the service they abused. But they have behaved in one predictable way over the years: They’re stingy, and won’t pay for anything unless it’s absolutely necessary, despite the fact that they’re raking in cash by the boatload. But that seemed to change this week when we saw a number of Web sites pop up […]
By Marco Giuliani Last Wednesday, Microsoft published a blog post detailing a significant update to a piece of malware named Popureb. The malware adds code to the Master Boot Record, or MBR, a region of the hard disk that’s read by the PC during bootup, long before the operating system has had a chance to get started. Researchers sometimes refer to these kinds of malware as bootkits, or a rootkit which loads at such a low level during the boot process that it is invisible to the operating system, and therefore very difficult to remove. Microsoft researcher Chun Feng detailed […]
For years, the makers of those snake oil security programs we call Rogue Security Products have spent considerable effort making up new names, developing unique graphic design standards, and inventing backstories for their utterly useless, expensive scam products. Now a new rogue has taken this never ending shell game one step further, releasing a single program that calls itself one of five different names, depending on what button an unfortunate victim clicks in a highly deceptive dialog box. Let’s call it what it really is, though: A malicious play in five acts. The rogue’s delivery method, or Act 1 in […]
Ransomware is nothing new, but a Ukrainian ransomware Trojan that came over the transom last week demonstrated that the concept of “payment” can extend to services other than banking or finance. In this case, the Trojan (which we and several other AV companies call Trojan-Ransom-Krotten) thoroughly locks down the infected system then demands payment—in the form of credit paid to the Ukrainian mobile phone provider Kyivstar, which the victim then has to transfer to the malware distributor’s account. Yes, Alice, the hacker wants you to pay his cellphone bill. Once the ransomware has taken hold on a victim’s computer, it […]
