Emotet is back and spamming again! After staying dormant for three months, the notorious trojan has commenced a high-volume malspam campaign to infect devices worldwide. So watch out for any unsolicited emails that revolve around financial and fake invoice themes. Moving on, a Chinese cyberespionage campaign has gone undetected for months. Why? That’s because of a unique radio-silence feature enabled in a new version of the Soul malware framework. This lets the malware variant communicate with the C2 server only at the specified hours set by the attackers and remain silent for the rest of the time. The malware is currently being used to target high-profile government entities in Southeast Asia. 

There’s also a security update from Google for Chrome 111. Around 40 vulnerabilities, eight of which were high-severity flaws, have been addressed in the latest iteration of the browser. Some of these flaws impacting the browser components were stack buffer overflow vulnerability, use-after-free vulnerability, and a type confusion flaw.
