Threat actors associated with North Korea are continuing to target the cybersecurity community using a zero-day bug in unspecified software over the past several weeks to infiltrate their machines. A search on X shows that the now-suspended account has been active since at least October 2022, with the actor releasing proof-of-concept exploit code for high-severity privilege escalation flaws in the Windows Kernel such as CVE-2021-34514 and CVE-2022-21881.
Google's Threat Analysis Group says North Korean state hackers are again targeting security researchers in attacks using at least one zero-day in an undisclosed popular software. Researchers attacked in this campaign are involved in vulnerability research and development, according to Google's team of security experts that protects the company's users from state-sponsored attacks.
The North Korean threat actor known as Andariel has been observed employing an arsenal of malicious tools in its cyber assaults against corporations and organizations in the southern counterpart.

A hitherto undocumented threat actor operating for nearly a decade and codenamed MoustachedBouncer has been attributed to cyber espionage attacks aimed at foreign embassies in Belarus. "To compromise their targets, MoustachedBouncer operators tamper with their victims' internet access, probably at the ISP level, to make Windows believe it's behind a captive portal," Faou said.
"The attackers aimed to establish a permanent channel for data exfiltration, including data stored on air-gapped systems," Kaspersky said in an analysis spotlighting APT31's previously undocumented tradecraft. Some variants of the second-stage backdoors also come with features designed to look up file names in the Microsoft Outlook folder, execute remote commands, and employ the third-step component to complete the data exfiltration step in the form of RAR archive files.
Two North Korean hacker groups had access to the internal systems of Russian missile and satellite developer NPO Mashinostoyeniya for five to six months, cyber security firm SentinelOne asserted on Monday. The attack illustrates potential North Korean efforts to advance development of missile and other military tech via cyber espionage.
