Windows and Linux systems are being targeted by a ransomware variant called HelloXD, with the infections also involving the deployment of a backdoor to facilitate persistent remote access to infected hosts. “Unlike other ransomware groups, this ransomware family doesn’t have an active leak site; instead it prefers to direct the impacted victim to negotiations through Tox

BPFDoor isn’t new to the cyberattack game — in fact, it’s gone undetected for years — but PwC researchers discovered the piece of malware in 2021. Subsequently, the cybersecurity community is learning more about the stealthy nature of malware, how it works, and how it can be prevented. What’s BPFDoor? BPFDoor is a piece of malware associated with China-based

Cybersecurity researchers have disclosed details of two medium-security flaws in Mitel 6800/6900 desk phones that, if successfully exploited, could allow an attacker to gain root privileges on the devices. Tracked as CVE-2022-29854 and CVE-2022-29855 (CVSS score: 6.8), the access control issues were discovered by German penetration testing firm SySS, following which patches were shipped in May
