![]() SANDBOXIE CHROME NOT WORKING DRIVERPreviously, the “Bring Your Own Driver” method was seen being used by the North Korean hacking group Lazarus, which involved a Dell hardware driver.īleeping Computer highlights how system administrators can protect their PCs by putting the MSI driver (RTCore64.sys) that is being targeted into an active blocklist.īlackByte’s ransomware efforts first came to light in 2021, with the FBI stressing that the hacking group was behind certain cyberattacks on the government. SANDBOXIE CHROME NOT WORKING DRIVERSShould any be found by the search, BlackByte disables its ability to function.īecause of the sophisticated nature of the technique used by the threat actors, Sophos warned that they will continue to exploit legitimate drivers in order to bypass security products. However, this element breaches Microsoft’s security guidelines on kernel memory access.ĭue to the exploit, threat actors can freely read, write, or execute code within a system’s kernel memory.īlackByte is naturally keen to avoid being detected so as to not have its hacks analyzed by researchers, Sophos stated - the company pointed toward attackers looking for any debuggers running on the system and then quitting.įurthermore, the group’s malware scans the system for any potential hooking DLLs connected to Avast, Sandboxie, Windows DbgHelp Library, and Comodo Internet Security. ![]() Researchers from cybersecurity company Sophos detail how the MSI graphics driver that is targeted by the ransomware gang offers I/O control codes that can be accessed through user-mode processes. The vulnerable drivers are able to pass an inspection via a valid certificate, and they also feature high privileges on the PC itself. That is, I can save items using Zotero plugin for Firefox, but only as web pages - most of the time even 'embedded metadata' option does not work. The problem is, Zotero translators do not work, if I run Firefox sandboxed. All programs and extensions are the latest updated versions. Once the drivers have been turned off by the hackers, they can operate under the radar due to the lack of multiple endpoint detection and response (EDR). Im using Zotero Standalone, Firefox and Sandboxie. Security programs that rely on such drivers are therefore unable to detect a breach, with the technique itself being labeled as “Bring Your Own Driver” by researchers. ![]() ![]() Fitbit Versa 3Ī security flaw has allowed a ransomware gang to effectively prevent antivirus programs from running properly on a system.Īs reported by Bleeping Computer, the BlackByte ransomware group is utilizing a newly discovered method related to the RTCore64.sys driver to circumvent more than 1,000 legitimate drivers. ![]()
