An ongoing worldwide campaign is pushing new malware dubbed Mosaic loader camouflaged as cracked software via search engine advertising to infect wannabe software pirates’ systems. MosaicLoader is a malware downloader designed by its creators to deploy more second-stage payloads on infected systems. The attackers are camouflaging their droppers as executables belonging to legitimate software, using similar icons and including info such as company names and descriptions within the files’ metadata info to pass superficial scrutiny. The best way to defend against Mosaicloader is to avoid downloading cracked software from any source.
