Summary

Hide ▲

Star Blizzard (ColdRiver/Calisto) continued a spear-phishing campaign in May and June 2025 against Reporters Without Borders (RSF) and another organization, using impersonated trusted contacts, compromised-website redirects, and a custom Adversary-in-the-Middle (AiTM) kit to harvest ProtonMail credentials and relay 2FA prompts. The activity fits the group’s long-running focus on Western entities backing Ukraine and shows continued use of credential harvesting tactics, including modified ProtonMail pages and attacker-controlled API handling for CAPTCHA and authentication.

    Coldriver shifts to NoRobot, YesRobot and MaybeRobot

    Initial Disclosure

    GTIG said Coldriver, also tracked as Star Blizzard, Callisto and UNC4057, had moved from LostKeys to a new malware chain built around NoRobot, YesRobot and MaybeRobot. The chain uses a ClickFix-style phishing lure, a fake CAPTCHA page, a malicious DLL launched via rundll32.exe, and downloads from inspectguarantee[.]org, while also reflecting a faster development and operations tempo in espionage operations against high-profile NGOs, former intelligence and military officers, and NATO governments.
