Cybersecurity researchers are raising alarms as the Silver Fox group expands its Winos 4.0 malware attacks from China and Taiwan to Japan and Malaysia. This malware, also known as ValleyRAT, is now being delivered through another remote access trojan called HoldingHands RAT. The campaign mainly uses phishing emails that trick users into opening PDFs, which look like official documents from the Ministry of Finance but contain nasty embedded links.

Pei Han Liao from Fortinet's FortiGuard Labs pointed out that these malicious documents include multiple links, one of which leads to the Winos 4.0 malware. This threat has a habit of spreading through phishing and SEO poisoning, luring victims to fake sites that pretend to be legitimate software like Google Chrome and Telegram. If you’re in those regions, keep your guard up and think twice before clicking on suspicious emails.
