The threat actors behind the Mispadu banking Trojan have become the latest to exploit a now-patched Windows SmartScreen security bypass flaw to compromise users in Mexico.
The attacks entail a new variant of the malware that was first observed in 2019, Palo Alto Networks Unit 42 said in a report published last week.
The latest infection chain identified by Unit 42 employs rogue internet shortcut files contained within bogus ZIP archive files that leverage CVE-2023-36025 (CVSS score: 8.8), a high-severity bypass flaw in Windows SmartScreen. It was addressed by Microsoft in November 2023.
"This exploit revolves around the creation of a specifically crafted internet shortcut file (.URL) or a hyperlink pointing to malicious files that can bypass SmartScreen's warnings," security researchers Daniela Shalev and Josh Grunzweig said.
