      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.

      Please enjoy this encore of Research Saturday. This week we are joined by ⁠Silas Cutler⁠, Principal Security Researcher at ⁠Censys⁠, asking the important question of "Will the Real Volt Typhoon Please Stand Up?" The FBI's disruption of the KV Botnet in December 2023, attributed to the Chinese threat group Volt Typhoon, targeted infected systems but did not affect the botnet's control infrastructure. Despite law enforcement efforts and technical exposure, the botnet's infrastructure has remained largely stable, with only changes in hosting providers, raising questions about whether another party operates the botnet. Censys scanning data from 2024 shows a shift in the botnet's control servers, indicating a response to disruption attempts, while the botnet's operators have shown limited efforts to obscure their infrastructure.

      This week we are joined by Kyle Lefton, Security Researcher from Akamai, who is diving into their work on "Two Botnets, One Flaw - Mirai Spreads Through Wazuh Vulnerability." Akamai researchers have observed active exploitation of CVE-2025-24016, a critical RCE vulnerability in Wazuh, by two Mirai-based botnets. The campaigns highlight how quickly attackers are adapting proof-of-concept exploits to spread malware, underscoring the urgency of patching vulnerable systems. One botnet appears to target Italian-speaking users, suggesting regionally tailored operations. We'd love to hear from you. We're conducting our annual audience survey to learn more about our listeners. We're collecting your insights until August 31, 2025. You can find our survey here.
