The annual report is always filled with useful security information. Here are several of the most important lessons from this year's edition.

A technically sophisticated threat actor known as SeaFlower has been targeting Android and iOS users as part of an extensive campaign that mimics official cryptocurrency wallet websites intending to distribute backdoored apps that drain victims' funds. Said to be first discovered in March 2022, the cluster of activity "hint[s] to a strong relationship with a Chinese-speaking entity yet to be

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,

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

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 chat and onion-based

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,'" Zscaler ThreatLabz researchers Niraj Shivtarkar and Avinash Kumar said in a report published last week.
