Confirmed: Microsoft Windows Zero-Day Exploit Used In Government Espionage Operation


![]()
It has been revealed that a threat actor once best known for cyber bank robbery in Russia has made a move to espionage. The highly targeted attacks against government institutions in Eastern Europe, which took place during June 2019, employed the use of a Microsoft Windows zero-day exploit. In and of itself this isn't unusual as there have been plenty of Windows zero-days discovered. However, this is the first time that researchers had seen the Buhtrap group using a zero-day attack, although the group has been involved in the cyber-spying business for some years now across Eastern Europe and Central Asia.
Anton Cherepanov, a senior malware researcher at security vendor ESET, explained how the zero-day exploit abused a local privilege escalation vulnerability in Microsoft Windows in order to run arbitrary code and install applications, and view or change data on the compromised systems. As soon as the researchers had properly analyzed the exploit, it was reported to the Microsoft Security Response Center, and a fix was included in the July 9 "Patch Tuesday" update.
The vulnerability itself only impacted older versions of Windows, specifically variations of Windows and Windows Server 2008. This is because, as Cherepanov explained, "since Windows 8 a user process is not allowed to map the NULL page. Microsoft back-ported this mitigation to Windows 7 for x64-based systems." The advice, predictably, is to upgrade to a newer version of the operating system if possible. Especially as critical security updates will disappear soon when extended support for Windows 7 Service Pack 1 ends in January 2020. Gavin Millard, vice-president of intelligence at Tenable, warns users not to be complacent seeing as the vulnerability is "now being actively exploited in the wild," advising that "patches should be deployed as soon as possible."

Samsung, Red Hat to Work on Linux Drivers for Future Tech
The metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world.
Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility.
