In many instances, researchers and engineers have found ways to hack into modern, internet-capable cars, as has been documented and reported several times. One famous example is the Chrysler Jeep hack that researchers Charlie Miller and Chris Valasek discovered. This hack and those that have come before it have mostly been reliant on specific vulnerabilities in specific makes and/or brands of cars. And once reported, these vulnerabilities were quickly resolved. But what should the security industry’s response be when a hack is found that is not only successful in being able to drastically affect the performance and function of the car, but is also stealthy and vendor neutral?Read More
Cybercriminals targeting gamers are nothing new. We’ve reported many similar incidents in the past, from fake game apps to real-money laundering through online game currencies. Usually the aim is simple: to steal personal information and monetize it. And usually, for that purpose the game itself is abused.
In the particular scenario we are describing in this blog post, however, it is not the game that is being abused by the cybercriminals, but rather one of the communication tools used by the game players. We’re referring to Discord, a new-generation chat platform that gamers frequently use, with a user base of more than 45 million registered members.Read More
A malicious email campaign against Russian-speaking enterprises is employing a combination of exploits and Windows components to deliver a new backdoor that allows attackers to take over the affected system. The attack abuses various legitimate Windows components to run unauthorized scripts; this is meant to make detection and blocking more challenging, particularly by whitelisting-based solutions.
We’ve observed at least five runs from June 23 to July 27, 2017, each of which sent several malicious emails per target. Affected industries were financial institutions, including banks, and mining firms. Of note is how the attackers diversified their tactic—sending different emails for each run, per target.Read More
We’ve uncovered a new exploit kit in the wild through a malvertising campaign we’ve dubbed “ProMediads”. We call this new exploit kit Sundown-Pirate, as it’s indeed a bootleg of its precursors and actually named so by its back panel.
ProMediads has been active as early as 2016, employing Rig and Sundown exploit kits to deliver malware. Its activities dropped off in mid-February this year, but suddenly welled on June 16 via Rig. However, we noticed that ProMediads eschewed Rig in favor of Sundown-Pirate on June 25.
It’s worth noting that Sundown-Pirate is only employed by ProMediads so far. This could mean that it’s yet another private exploit kit, like the similarly styled GreenFlash Sundown exploit kit that was exclusively used by the ShadowGate campaign.Read More
A seven-year old vulnerability in Samba—an open-source implementation of the SMB protocol used by Windows for file and printer sharing—was patched last May but continues to be exploited. According to a security advisory released by the company, the vulnerability allows a malicious actor to upload a shared library to a writable share, causing the server to load and execute it. If leveraged successfully, an attacker could open a command shell in a vulnerable device and take control of it. It affects all versions of Samba since 3.5.0.Read More
