Despite the 2016 Olympics coming to a close, cybercriminals remain relentless in using the sporting event as a social engineering hook to distribute a banking Trojan. Earlier this month, we spotted a phishing campaign that led victims to unknowingly download the Banker malware. Although Banker has been in the wild for years, this time we see it using a Dynamic Loading Library (DLL) with malicious exported functions. One of the export calls used is to check if the victimized system is located in Brazil. If the geolocation points to Brazil, then another malicious file is downloaded. This particular new routine points to the possibility of the cybercriminals’ intention of riding on the popularity of the Olympics to lure users. Apart from Banker, there are reports indicating that other banking Trojans, are doing the same thing. For instance, Sphinx ZeuS has enhanced its capabilities because of the Olympics.Read More
For $50, one could purportedly get a lifetime license to upgradeable variants of WannaCry. We saw this advertisement in an Arabic-speaking underground forum on May 14, two days after WannaCry’s outbreak. Indeed, a threat that left a trail of significant damage in its wake was objectified into a commodity, and even a starting point for others to launch their own cybercriminal businesses.
WannaCry’s relatively low price also reflects another unique aspect of the Middle Eastern and North African underground: a sense of brotherhood. Unlike marketplaces in Russia and North America, for instance, where its players aim to make a profit, the Middle East and North Africa’s underground scene is an ironic juncture where culture, ideology, and cybercrime meet.Read More
The security industry as a whole loves collecting data, and researchers are no different. With more data, they commonly become more confident in their statements about a threat. However, large volumes of data require more processing resources, as extracting meaningful and useful information from highly unstructured data is particularly difficult. As a result, manual data analysis is often the only choice, forcing security professionals like investigators, penetration testers, reverse engineers, and analysts to process data through tedious and repetitive operations.Read More
Cerber set itself apart from other file-encrypting malware when its developers commoditized the malware, adopting a business model where fellow cybercriminals can buy the ransomware as a service. The developers earn through commissions—as much as 40%—for every ransom paid by the victim. Coupled with persistence, Cerber turned into a cybercriminal goldmine that reportedly earned its developers $200,000 in commissions in a month alone last year.
Being lucrative and customizable for affiliates, it’s no wonder that Cerber spawned various iterations. Our coverage of unique Cerber samples—based on feedback from Smart Protection Network™—shows enterprises and individual users alike are taking the brunt, with the U.S. accounting for much of Cerber’s impact. We’ve also observed Cerber’s adverse impact among organizations in education, manufacturing, public sector, technology, healthcare, energy, and transportation industries.
A reflection of how far Cerber has come in the threat landscape—and how far it’ll go—is Cerber Version 6, the ransomware’s latest version we’ve uncovered and monitored since early April this year. It sports multipart arrival vectors and refashioned file encryption routines, along with defense mechanisms that include anti-sandbox and anti-AV techniques.Read More
Kernel debugging gives security researchers a tool to monitor and control a device under analysis. On desktop platforms such as Windows, macOS, and Linux, this is easy to perform. However, it is more difficult to do kernel debugging on Android devices such as the Google Nexus 6P . In this post, I describe a method to perform kernel debugging on the Nexus 6P and the Google Pixel, without the need for any specialized hardware.Read More
