Daily Threat Briefing February 5, 2024

Windows users in Mexico are on the radar of cybercriminals planting an advanced version of the Mispadu banking trojan on their devices. The malware, part of the LATAM banking malware family, is using malicious internet shortcut files within ZIP archives. A similar account takeover threat hovers over a popular decentralized social network owing to a flaw that is rated 9.4 on the CVSS severity scale. Full details, however, will be disclosed on February 15, allowing admins time to patch.

Meanwhile, security researchers warned of a large-scale macOS cyberattack campaign distributing the Activator backdoor through cracked copies of popular software. Its multistage infection chain enables backdooring even if the user removes the cracked software.
