A Chinese advanced persistent threat (APT) known as Gallium has been observed using a previously undocumented remote access trojan in its espionage attacks targeting companies operating in Southeast Asia, Europe, and Africa. Called PingPull, the “difficult-to-detect” backdoor is notable for its use of the Internet Control Message Protocol (ICMP) for command-and-control (C2) communications, according to…
A novel hardware attack dubbed PACMAN has been demonstrated against Apple’s M1 processor chipsets, potentially arming a malicious actor with the capability to gain arbitrary code execution on macOS systems. It leverages “speculative execution attacks to bypass an important memory protection mechanism, ARM Pointer Authentication, a security feature that is used to enforce pointer integrity,”…
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…

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…
The Iranian state-sponsored threat actor tracked under the moniker Lyceum has turned to using a new custom .NET-based backdoor in recent campaigns directed against the Middle East. “The new malware is a .NET based DNS Backdoor which is a customized version of the open source tool ‘DIG.net,”http://thehackernews.com/” Zscaler ThreatLabz researchers Niraj Shivtarkar and Avinash Kumar…
