Who said there’s such a thing as a trusted Java applet? In situations where malicious attackers cannot directly exploit client-side vulnerabilities on the targeted host, they will turn to social engineering tricks, like legitimate-looking Java Applets, which will on the other hand silently download the malicious payload of the attacker, once the user confirms he trusts the Applet. Let’s profile a DIY (do-it-yourself) malicious Java Applet generator currently available for download at selected cybercrime-friendly online communities:

Participants in the dynamic cybercrime underground ecosystem are constantly working on new cybercrime-friendly releases in the form of malware bots, Remote Access Tools (RATs) and malware loaders. Continuing the “A peek inside…” series, in this post I will profile yet another DIY (do-it-yourself) malware bot, available at the disposal of cybercriminals at selected cybercrime-friendly online communities.
Security researchers from Webroot have intercepted a currently active, client-side exploits-serving malicious campaign that has already managed to infect 18,544 computers across the globe, through the BlackHole web malware exploitation kit. More details:
The thriving cybercrime underground marketplace has a lot to offer. From DIY botnet builders, DIY DDoS platforms, to platforms for executing clickjacking and likejacking campaigns, next to drive-by malware attacks, the ecosystem is always a step ahead of the industry established to fight back. Continuing the “A peek inside…” series, in this post I will profile yet another freely available DIY Botnet building tool – the Umbra Malware Loader.
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 […]
By Armando Orozco Be wary the next time you enter your passcode into your iPhone on the bus – someone could be shoulder surfing. In fact, a team of researchers from the University of North Carolina has developed a system to watch you pecking out characters on your phone, analyse the video, and produce a pretty accurate guess of what you were typing. When people talk about key loggers, they’re usually thinking about malware that sits on a computer and surreptitiously monitors what keys people are pressing. But these university researchers are applying an entirely different approach to key logging. […]
By Jacques Erasmus I’ve been having trouble sleeping lately, and last night I pinpointed why. October has presented me with a perfect storm of Internet security developments: I embarked on my first few weeks as chief information security officer for Webroot amidst the most significant consumer product launch the company has ever had. These activities alone would’ve been enough to keep corporate security top of mind 24/7, but their occurrence during Cyber Security Awareness Month further drove it home for me. So I thought perhaps it may be cathartic for me, and helpful for you, if I shared some of […]
By Ian Moyse, EMEA Channel Director It can seem at times that the only people who like change are Internet attackers. And they don’t just like it—they need it. Technology’s rapid changes give cybercriminals new attack vectors to exploit, and new ways to turn a profit out of someone else’s misfortune. Take phishing, for example. The concept is simple: Send an email disguised as a message from a bank, PayPal, or UPS. Wait for the user to click a link in the message, and enter their private details into a phishing site, and presto! The attacker attains financial or personal […]
As if we didn’t have enough to deal with this week — after a Microsoft patch Tuesday that brought with it a boatload of security updates for Windows, Office, Silverlight, Visual Studio, and other programs — some enterprising malware distributor is emailing around bogus tracking number malware dressed up in the icon of a PDF document, and that malware is downloading payloads named after the updaters that Windows Update retrieves during an update. The malware arrived into one of our spam collection points with an attachment named UPS_document.zip. Way to be original there, criminals. Inside the Zip file was an […]
After a prolonged absence, waves of Trojans distributed as Zipped email attachments have been showing up in our spam traps for a few weeks. The spam messages employ the same hackneyed shipping confirmation pretext as many previous iterations of this scam. This technique’s emergence as a common malware distribution method correlates with the emergence of Trojan-Downloader-Tacticlol. The messages claim to come from various express shippers, including DHL, UPS, and FedEx, as well as one that may have originated in a malware guy’s imagination: Post Express. And even though the distribution method mimics those used by Tacticlol, the payloads haven’t been […]
