Written by: Tyler McLellan, Austin Larsen Introduction Google Threat Intelligence Group (GTIG) continues to track UNC6671 actively conducting compromises leading to data theft extortion, despite the alleged announced retirement of the BlackFile extortion brand in May 2026. Telemetry and infrastructure analysis reveal that rather than disbanding, UNC6671 has diversified its operations across multiple extortion fronts including Redact, Pink, Helix, and Falcon. UNC6671 continues to rely on voice phishing (vishing) to target enterprise employees, posing as IT helpdesk staff facilitating mandatory…
Written by: Kelli Vanderlee, Stuart Carrera For years, the cybersecurity industry's understanding of software supply chain compromise has been anchored by a few watershed events, including Russian cyber espionage actor ICE RELIC’s (formerly known as APT29) 2020 compromise of SolarWinds and North Korean cyber espionage actor UNC4736's 2023 compromise of 3CX. However, Google Threat Intelligence Group (GTIG) has been tracking growth in threat activity targeting open source software repositories to conduct supply chain compromises over the past several years. A series of large scale open source s…
For years, security operations followed a familiar sequence: detect suspicious activity, investigate what happened, and respond before it caused significant harm. That model developed in a threat landscape where defenders had considerably more time to establish the facts and decide what to do next. In 2019, the average data breach took 206 days to identify and another 73 days to contain, creating a total breach lifecycle of 279 days.As the time between initial access and attacker movement continues to contract, security teams are being asked to operate within a much narrower window. AI is acc…
The Cybersecurity and Infrastructure Security Agency (CISA) has issued a postmortem on a data leak in which a contractor published dozens of internal CISA credentials -- including AWS Govcloud keys -- in a public GitHub repository for almost six months before being notified by KrebsOnSecurity. Experts say the gaps identified in the agency's initial response provide important lessons that all security teams should absorb.
Introduction Mandiant and Google Threat Intelligence Group (GTIG) have identified an active compromise and extortion campaign attributed to UNC6240 (ShinyHunters) targeting Oracle PeopleSoft application infrastructure. The activity was observed between May 27, 2026, and June 9, 2026 and is consistent with the exploitation of CVE-2026-35273, a critical remote code execution vulnerability (CVSS 9.8) in the Environment Management component. The exploitation of this vulnerability directly aligns with the observed targeting of Environment Management Hub (PSEMHUB) endpoints. Because this activity p…
Written by: Chad Reams, Tufail Ahmed, Keith Knapp, Ashley Frazer, Tyler McLellan Introduction From January through May 2026, Mandiant identified a financially motivated data theft extortion campaign executed by the threat cluster UNC3753 (also tracked as "Luna Moth," “Chatty Spider,” and "Silent Ransom Group") targeting dozens of organizations across professional, legal, and financial services in the United States. UNC3753 leverages voice phishing (vishing) and social engineering deception techniques to achieve remote access into corporate environments. Using pretexts such as data migration o…
Written by: Austin Larsen, Tyler McLellan, Genevieve Stark, Dan Ebreo Introduction Google Threat Intelligence Group (GTIG) has continued to track an expansive extortion campaign by UNC6671, a threat actor operating under the "BlackFile" brand, that targets organizations via sophisticated voice phishing (vishing) and single sign-on (SSO) compromise. By leveraging adversary-in-the-middle (AiTM) techniques to bypass traditional perimeter defenses and multi-factor authentication (MFA), UNC6671 gains deep access to cloud environments. The group primarily targets Microsoft 365 and Okta infrastructu…
Written by: Jamie Collier, Robin Grunewald Germany has reclaimed its position as a primary focus for cyber extortion in Europe. While data leak site (DLS) posts rose almost 50% globally in 2025, Google Threat Intelligence (GTI) data shows that the surge is hitting German infrastructure harder and faster than its regional neighbors, marking a significant return to the high-pressure levels previously observed in the country during 2022 and 2023. Cyber Criminals Pivoting Back to Germany Germany moved to the forefront of European data leak targets in 2025. Following a 2024 period where the UK led…
