Magnitude exploit kit resurfaced with Magniber, a previously unknown ransomware family that was observed being dropped only through that exploit kit at the time of analysis. The ransomware applied multiple South Korea-specific checks, including public IP and installed language, and deleted itself on non-Korean systems. On accepted systems it copied itself to the temp directory, used scheduled tasks for deployment, encrypted many file types, and displayed a minimal TXT ransom note. Its generated domains served both command-and-control requests and victim payment pages, with example paths such as /new1 and /end1 returning 16-character strings only under expected conditions. The targeting logic and country-gated server responses made the campaign unusually selective for ransomware operations.
