Today we are joined by ⁠Selena Larson⁠, Threat Researcher at ⁠Proofpoint⁠, and co-host of ⁠Only Malware in the Building⁠, as she discusses their work on "Amatera Stealer - Rebranded ACR Stealer With Improved Evasion, Sophistication." Proofpoint researchers have identified Amatera Stealer, a rebranded and actively developed malware-as-a-service (MaaS) variant of the former ACR Stealer, featuring advanced evasion techniques like NTSockets for stealthy C2 communication and WoW64 Syscalls to bypass user-mode defenses. Distributed via ClearFake web injects and the ClickFix technique, Amatera leverages multilayered PowerShell loaders, blockchain-based hosting, and creative social engineering to compromise victims. With enhanced capabilities to steal browser data, crypto wallets, and other sensitive files, Amatera poses a growing threat in the wake of disruptions to competing stealers like Lumma. Complete our annual ⁠audience survey⁠ before August 31. The research can be found here: ⁠Amatera Stealer: Rebranded ACR Stealer With Improved Evasion, Sophistication Learn more about your ad choices.
