The Council of the European Union has sanctioned three individuals for allegedly carrying out "malicious cyber activities" against Estonia. The three Russian nationals – Nikolay Alexandrovich Korchagin, Vitaly Shevchenko, and Yuriy Fedorovich Denisov – are officers of the General Staff of the Armed Forces of the Russian Federation (GRU) Unit 29155, it said. Per the council decision, all the individuals are said to be responsible for cyber attacks against computer systems with the aim of collecting data from the data systems of multiple institutions with an aim to gain insights into the cyber security policy of Estonia. "The cyber-attacks granted attackers unauthorized access to classified information and sensitive data stored within several government ministries — including Economic Affairs and Communications, Social Affairs, and Foreign Affairs — leading to the theft of thousands of confidential documents," per the Council . This included business secrets, h...

The Computer Emergency Response Team of Ukraine (CERT-UA) has warned of a new set of cyber attacks that it said were aimed at defense companies in the country as well as its security and defense forces. The phishing attacks have been attributed to a Russia-linked threat actor called UAC-0185 (aka UNC4221), which has been active since at least 2022. "The phishing emails mimicked official messages from the Ukrainian League of Industrialists and Entrepreneurs," CERT-UA said . "The emails advertised a conference held on December 5th in Kyiv, aimed at aligning the products of domestic defense industry companies with NATO standards." The email messages come embedded with a malicious URL that urges the recipients to click on it to view "important information" related to their participation in the conference. But in reality, doing so results in the download of a Windows shortcut file that, upon opening, is designed to execute an HTML Application, which, in t...

Microsoft Entra ID (formerly Azure Active Directory) is the backbone of modern identity management, enabling secure access to the applications, data, and services your business relies on. As hybrid work and cloud adoption accelerate, Entra ID plays an even more central role — managing authentication, enforcing policy, and connecting users across distributed environments. That prominence also makes it a prime target. Microsoft reports over 600 million attacks on Entra ID every day. These aren't just random attempts, but include coordinated, persistent, and increasingly automated campaigns designed to exploit even small vulnerabilities. Which brings us to the core question: Are Entra ID's native protections enough? Where do they fall short — and what steps should you take to close the gaps and ensure you're covered? Understanding Entra ID At its core, Microsoft Entra ID is your enterprise identity and access management system. It defines how users prove who they are, what resources...

The U.S. government and a coalition of international partners have officially attributed a Russian hacking group tracked as Cadet Blizzard to the General Staff Main Intelligence Directorate (GRU) 161st Specialist Training Center ( Unit 29155 ). "These cyber actors are responsible for computer network operations against global targets for the purposes of espionage, sabotage, and reputational harm since at least 2020," the agencies said . "Since early 2022, the primary focus of the cyber actors appears to be targeting and disrupting efforts to provide aid to Ukraine." Targets of the attacks have focused on critical infrastructure and key resource sectors, including the government services, financial services, transportation systems, energy, and healthcare sectors of North Atlantic Treaty Organization (NATO) members, the European Union, Central American, and Asian countries. The joint advisory, released last week as part of a coordinated exercise dubbed Operatio...

The threat actors behind the RomCom RAT have been suspected of phishing attacks targeting the  upcoming NATO Summit  in Vilnius as well as an identified organization supporting Ukraine abroad. The findings come from the BlackBerry Threat Research and Intelligence team, which  found  two malicious documents submitted from a Hungarian IP address on July 4, 2023. RomCom, also tracked under the names Tropical Scorpius, UNC2596, and Void Rabisu, was recently observed staging cyber attacks against politicians in Ukraine who are working closely with Western countries and a U.S.-based healthcare organization involved with aiding refugees fleeing the war-torn country. Attack chains mounted by the group are geopolitically motivated and have employed spear-phishing emails to point victims to cloned websites hosting trojanized versions of popular software. Targets include militaries, food supply chains, and IT companies. The latest lure documents identified by BlackBerry ...

The Russia-linked  APT29  (aka Cozy Bear) threat actor has been attributed to an ongoing cyber espionage campaign targeting foreign ministries and diplomatic entities located in NATO member states, the European Union, and Africa. According to Poland's Military Counterintelligence Service and the CERT Polska team, the observed activity shares tactical overlaps with a cluster tracked by Microsoft as  Nobelium , which is known for its high-profile  attack on SolarWinds  in 2020. Nobelium's operations have been attributed to Russia's Foreign Intelligence Service ( SVR ), an organization that's tasked with protecting "individuals, society, and the state from foreign threats." That said, the campaign represents an evolution of the Kremlin-backed hacking group's tactics, indicating  persistent attempts  at improving its cyber weaponry to infiltrate victim systems for intelligence gathering. "New tools were used at the same time and independently of eac...

A year back, Security Researchers from the Antivirus firm Kaspersky found a sophisticated piece of malware which they dubbed as ' MiniDuke ', designed specifically to collect and steal strategic insights and highly protected political information, which is a subject to states' security. Now, once again the MiniDuke virus is spreading in wild via an innocent looking but fake PDF documents related to Ukraine , while the researcher at F-Secure were browsing the set of extracted decoy documents from a large batch of potential MiniDuke Samples. " This is interesting considering the current crisis in the area ," Mikko Hypponen, the CTO of security research firm F-Secure, wrote on Tuesday. The Hacker News reported a year ago about the malicious malware that uses an exploit ( CVE-2013-0640 ) of the famous and actively used Adobe Reader . MiniDuke malware written in assembly language with its tiny file size (20KB), and uses hijacked Twitter accounts for Command ...
