Since early March 2025, Volexity has observed multiple suspected Russian threat actors conducting highly targeted social engineering operations aimed at gaining access to the Microsoft 365 (M365) accounts of targeted individuals. This activity comes on the heels of attacks Volexity reported on back in February 2025, where Russian threat actors were discovered targeting users and organizations through Device Code Authentication phishing...
The Russian hacking group known as Gamaredon, or “Shuckworm,” has been making headlines with its sophisticated cyberattacks targeting Western military missions. This group has evolved its tactics, techniques, and procedures (TTPs) to enhance stealth and effectiveness, transitioning from Visual Basic Script (VBS) to PowerShell-based tools. PowerShell is a task automation framework from Microsoft, often used by attackers to execute commands and scripts on Windows systems. This shift, as reported by Symantec, highlights their strategic move to obfuscate, or hide, payloads and leverage legitimate services for evasion. Gamaredon’s recent campaigns have notably involved the use of malicious removable drives, targeting Western military missions in Ukraine with .LNK files that initiate infections upon execution. These developments underscore the group’s persistent threat to geopolitical entities, particularly those related to the Ukrainian military.

Google Threat Intelligence Group (GTIG) has observed increasing efforts from several Russia state-aligned threat actors to compromise Signal Messenger accounts used by individuals of interest to Russia's intelligence services. While this emerging operational interest has likely been sparked by wartime demands to gain access to sensitive government and military communications in the context of Russia's re-invasion of Ukraine, we anticipate the tactics and methods used to target Signal will grow in prevalence in the near-term and proliferate to additional threat actors and regions outside the Ukrainian theater of war.
Microsoft Threat Intelligence Center discovered an active and successful device code phishing campaign by a threat actor we track as Storm-2372. Our ongoing investigation indicates that this campaign has been active since August 2024 with the actor creating lures that resemble messaging app experiences including WhatsApp, Signal, and Microsoft Teams. Storm-2372’s targets during this time have included government, non-governmental organizations (NGOs), information technology (IT) services and technology, defense, telecommunications, health, higher education, and energy/oil and gas in Europe, North America, Africa, and the Middle East. Microsoft assesses with medium confidence that Storm-2372 aligns with Russian interests, victimology, and tradecraft.
Starting in mid-January 2025, Volexity identified several social-engineering and spear-phishing campaigns by Russian threat actors aimed at compromising Microsoft 365 (M365) accounts. These attack campaigns were highly targeted and carried out in a variety of ways. The majority of these attacks originated via spear-phishing emails with different themes. In one case, the eventual breach began with highly tailored outreach via Signal.Through its investigations, Volexity discovered that Russian threat actors were impersonating a variety of individuals
Another undersea data cable, this time connecting Sweden and Latvia, has been severed in the Baltic Sea, officials from both countries said Sunday. The incident prompted Sweden to launch a criminal probe into the matter and seize a "suspect vessel" vessel headed for Russia.
The Eagle S is suspected of damaging the Estlink-2 power cable which runs under the Baltic Sea between Finland and Estonia by dragging its anchor along the seabed on Christmas Day.
Police in Finland say the crew of a Russia-linked tanker suspected of damaging a power cable under the Baltic Sea have been detained indefinitely.
The Eagle S crew consists of 24 people with Finland’s Central Criminal Police imposing movement restrictions on eight.
