North Korean cybercriminals are using a trio of malware—FastFire, FastViewer, and FastSpy—against South Koreans. The Android malware set is capable of compromising almost all phone functions, ranging from hijacking communication channels to taking over the camera. In other news, researchers warned about a critical GitHub vulnerability exploiting which, an attacker can infect all applications and other code relying on the targeted GitHub repository. The hack is possible if a hacker applies the repojacking technique.

What more? Researchers found cyber adversaries posing as the Hungarian government to distribute Warzone RAT. The trick involves informing unsuspecting users about the arrival of new credentials pertaining to a government portal.

Malware campaign targeting South Korea
North Korean cyberespionage group Kimsuky was seen using three different malware to infect Android users in South Korea. The malware strains were identified as FastFire, FastViewer, and FastSpy.

Top Vulnerabilities Reported in the Last 24 Hours


High-severity GitHub flaw
Checkmarx uncovered a sensitive GitHub flaw that could let an unauthenticated user seize a GitHub repository and potentially infect all applications with malicious code by pulling off supply chain attacks. Attackers are reportedly using Repo Jacking, a technique to penetrate a GitHub repository by exploiting a “hidden” logical flaw in the architecture that makes renamed users susceptible to attacks.

Unfixed bugs in Windows
Two bugs in different Windows versions have been allowing cybercriminals to slip malicious documents past Microsoft's Mark of the Web (MotW) security feature. The researcher, who discovered the issues, stated that Microsoft has not released any fixes or any workaround for organizations to protect their users. The MotW feature offers protection to users against files from unsolicited sources on the internet.
