In an uncanny incident, a notorious cybercriminal group turned to TikTok’s ‘Invisible Challenge’ to trick users into downloading the W4SP Stealer malware. With over a million views on such videos, threat actors managed to steal and add more than 30,000 members’ accounts to their Discord servers. In other headlines, a critical UEFI vulnerability in Acer laptops was discovered to pose a major threat to users. Criminals can hijack the OS loading process to bypass or even disable protections to plant payloads with system privileges.
What more? The CISA would like to pull your attention toward a high-severity bug in Oracle Fusion Middleware that is under heavy exploitation by hackers. A hacker could completely take over Access Manager instances by abusing the flaw.
