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

Cybersecurity researchers have shed light on a sophisticated information stealer campaign that impersonates legitimate brands to distribute malware like DanaBot and StealC . The activity cluster, orchestrated by Russian-speaking cybercriminals and collectively codenamed Tusk, is said to encompass several sub-campaigns, leveraging the reputation of the platforms to trick users into downloading the malware using bogus sites and social media accounts. "All the active sub-campaigns host the initial downloader on Dropbox," Kaspersky researchers Elsayed Elrefaei and AbdulRhman Alfaifi said . "This downloader is responsible for delivering additional malware samples to the victim's machine, which are mostly info-stealers (DanaBot and StealC) and clippers." Of the 19 sub-campaigns identified to date, three are said to be currently active. The name "Tusk" is a reference to the word "Mammoth" used by the threat actors in log messages associated with t

Even as cyber threats become increasingly sophisticated, the number one attack vector for unauthorized access remains phished credentials ( Verizon DBIR, 2024 ). Solving this problem resolves over 80% of your corporate risk, and a solution is possible.  However, most tools available on the market today cannot offer a complete defense against this attack vector because they were architected to deliver probabilistic defenses. Learn more about the characteristics of Beyond Identity that allow us to deliver deterministic defenses.  The Challenge: Phishing and Credential Theft Phishing attacks trick users into revealing their credentials via deceptive sites or messages sent via SMS, email, and/or voice calls. Traditional defenses, such as end-user training or basic multi-factor authentication (MFA), lower the risk at best but cannot eliminate it. Users may still fall prey to scams, and stolen credentials can be exploited. Legacy MFA is a particularly urgent problem, given that attackers

Russian and Belarusian non-profit organizations, Russian independent media, and international non-governmental organizations active in Eastern Europe have become the target of two separate spear-phishing campaigns orchestrated by threat actors whose interests align with that of the Russian government. While one of the campaigns – dubbed River of Phish – has been attributed to COLDRIVER , an adversarial collective with ties to Russia's Federal Security Service (FSB), the second set of attacks have been deemed the work of a previously undocumented threat cluster codenamed COLDWASTREL. Targets of the campaigns also included prominent Russian opposition figures-in-exile, officials and academics in the US think tank and policy space, and a former U.S. ambassador to Ukraine, according to a joint investigation from Access Now and the Citizen Lab. "Both kinds of attacks were highly tailored to better deceive members of the target organizations," Access Now said . "The m

A Russia-linked threat actor has been linked to a new campaign that employed a car for sale as a phishing lure to deliver a modular Windows backdoor called HeadLace . "The campaign likely targeted diplomats and began as early as March 2024," Palo Alto Networks Unit 42 said in a report published today, attributing it with medium to high level of confidence to APT28 , which is also referred to as BlueDelta, Fancy Bear, Fighting Ursa, Forest Blizzard, FROZENLAKE, Iron Twilight, ITG05, Pawn Storm, Sednit, Sofacy, and TA422. It's worth noting that car-for-sale phishing lure themes have been previously put to use by a different Russian nation-state group called APT29 as far back as May 2023, indicating that APT28 is repurposing successful tactics for its own campaigns. Earlier this May, the threat actor was implicated in a series of campaigns targeting networks across Europe with the HeadLace malware and credential-harvesting web pages. The attacks are characterize

The Computer Emergency Response Team of Ukraine (CERT-UA) has alerted of a spear-phishing campaign that targeted a scientific research institution in the country with malware known as HATVIBE and CHERRYSPY. The agency attributed the attack to a threat actor it tracks under the name UAC-0063 , which was previously observed targeting various government entities to gather sensitive information using keyloggers and backdoors. The attack is characterized by the use of a compromised email account belonging to an employee of the organization to send phishing messages to "dozens" of recipients containing a macro-laced Microsoft Word (DOCX) attachment. Opening the document and enabling macros results in the execution of an encoded HTML Application (HTA) named HATVIBE, which sets up persistence on the host using a scheduled task and paves the way for a Python backdoor codenamed CHERRYSPY, which is capable of running commands issued by a remote server. CERT-UA said it detected &q

Two Russian nationals have pleaded guilty in a U.S. court for their participation as affiliates in the LockBit ransomware scheme and helping facilitate ransomware attacks across the world. The defendants include Ruslan Magomedovich Astamirov, 21, of Chechen Republic, and Mikhail Vasiliev, 34, a dual Canadian and Russian national of Bradford, Ontario. Astamirov was arrested in Arizona by U.S. law enforcement agencies in May 2023. Vasiliev, who is already wanted for similar charges in Canada, was sentenced to nearly four years in jail. He was subsequently extradited to the U.S. last month. The development comes more than two months after the U.K. National Crime Agency (NCA) unmasked a 31-year-old Russian national named Dmitry Yuryevich Khoroshev as the administrator and developer of the LockBit ransomware operation. LockBit, which is estimated to have attacked over 2,500 entities since its appearance towards the end of 2019, raking in at least approximately $500 million in ranso

TeamViewer on Thursday disclosed it detected an "irregularity" in its internal corporate IT environment on June 26, 2024. "We immediately activated our response team and procedures, started investigations together with a team of globally renowned cyber security experts and implemented necessary remediation measures," the company said in a statement. It further noted that its corporate IT environment is completely cut off from the product environment and that there is no evidence to indicate that any customer data has been impacted as a result of the incident. It did not disclose any details as to who may have been behind the intrusion and how they were able to pull it off, but said an investigation is underway and that it would provide status updates as and when new information becomes available. TeamViewer, based in Germany, is the maker of remote monitoring and management (RMM) software that allows managed service providers (MSPs) and IT departments to mana

A 22-year-old Russian national has been indicted in the U.S. for his alleged role in staging destructive cyber attacks against Ukraine and its allies in the days leading to Russia's full-blown military invasion of Ukraine in early 2022. Amin Timovich Stigal, the defendant in question, is assessed to be affiliated with the Main Directorate of the General Staff of the Armed Forces of the Russian Federation (GRU). He remains at large. If convicted, he faces a maximum penalty of five years in prison. Concurrent with the action, the U.S. Department of State's Rewards for Justice program is offering a reward of up to $10 million for information pertaining to his whereabouts or the malicious cyber attacks he is associated with. "The defendant conspired with Russian military intelligence on the eve of Russia's unjust and unprovoked invasion of Ukraine to launch cyberattacks targeting the Ukrainian government and later targeting its allies, including the United States,&quo

Russian organizations have been targeted by a cybercrime gang called ExCobalt using a previously unknown Golang-based backdoor known as GoRed. "ExCobalt focuses on cyber espionage and includes several members active since at least 2016 and presumably once part of the notorious Cobalt Gang ," Positive Technologies researchers Vladislav Lunin and Alexander Badayev said in a technical report published this week. "Cobalt attacked financial institutions to steal funds. One of Cobalt's hallmarks was the use of the CobInt tool , something ExCobalt began to use in 2022." Attacks mounted by the threat actor have singled out various sectors in Russia over the past year, including government, information technology, metallurgy, mining, software development, and telecommunications. Initial access to environments is facilitated by taking advantage of a previously compromised contractor and a supply chain attack, wherein the adversary infected a component used to bu

State-sponsored actors with ties to Russia have been linked to targeted cyber attacks aimed at French diplomatic entities, the country's information security agency ANSSI said in an advisory. The attacks have been attributed to a cluster tracked by Microsoft under the name Midnight Blizzard (formerly Nobelium), which overlaps with activity tracked as APT29 , BlueBravo, Cloaked Ursa, Cozy Bear, and The Dukes. While the monikers APT29 and Midnight Blizzard have been interchangeably used to refer to intrusion sets associated with the Russian Foreign Intelligence Service (SVR), ANSSI said it prefers to treat them as disparate threat clusters alongside a third one dubbed Dark Halo , which has been held responsible for the 2020 supply chain attack via SolarWinds software. "Nobelium is characterized by the use of specific codes, tactics, techniques, and procedures. Most of Nobelium campaigns against diplomatic entities use compromised legitimate email accounts belonging to dipl

A previously undocumented "flexible" backdoor called  Kapeka  has been "sporadically" observed in cyber attacks targeting Eastern Europe, including Estonia and Ukraine, since at least mid-2022. The findings come from Finnish cybersecurity firm WithSecure, which attributed the malware to the Russia-linked advanced persistent threat (APT) group tracked as  Sandworm  (aka APT44 or Seashell Blizzard). Microsoft is tracking the same malware under the name KnuckleTouch. "The malware [...] is a flexible backdoor with all the necessary functionalities to serve as an early-stage toolkit for its operators, and also to provide long-term access to the victim estate," security researcher Mohammad Kazem Hassan Nejad  said . Kapeka comes fitted with a dropper that's designed to launch and execute a backdoor component on the infected host, after which it removes itself. The dropper is also responsible for setting up persistence for the backdoor either as a schedul

An installer for a tool likely used by the Russian Consular Department of the Ministry of Foreign Affairs (MID) has been backdoored to deliver a remote access trojan called  Konni RAT  (aka  UpDog ). The findings come from German cybersecurity company DCSO, which linked the activity as originating from the Democratic People's Republic of Korea (DPRK)-nexus actors targeting Russia. The Konni (aka Opal Sleet, Osmium, or  TA406 ) activity cluster has an established pattern of deploying Konni RAT against Russian entities, with the threat actor also linked to  attacks directed against MID  at least since October 2021. In November 2023, Fortinet FortiGuard Labs  revealed  the use of Russian-language Microsoft Word documents to deliver malware capable of harvesting sensitive information from compromised Windows hosts. DCSO said the packaging of Konni RAT within software installers is a technique  previously adopted  by the group in October 2023, when it was found to leverage a backd

The Russia-linked threat actor known as COLDRIVER has been observed evolving its tradecraft to go beyond credential harvesting to deliver its first-ever custom malware written in the Rust programming language. Google's Threat Analysis Group (TAG), which shared details of the latest activity, said the attack chains leverage PDFs as decoy documents to trigger the infection sequence. The lures are sent from impersonation accounts. COLDRIVER, also known by the names Blue Callisto, BlueCharlie (or TAG-53), Calisto (alternately spelled Callisto), Dancing Salome, Gossamer Bear, Star Blizzard (formerly SEABORGIUM), TA446, and UNC4057, is known to be active since 2019, targeting a wide range of sectors. This includes academia, defense, governmental organizations, NGOs, think tanks, political outfits, and, recently, defense-industrial targets and energy facilities. "Targets in the U.K. and U.S. appear to have been most affected by Star Blizzard activity, however activity has al

Cybersecurity researchers have shed light on the inner workings of the ransomware operation led by Mikhail Pavlovich Matveev, a Russian national who was  indicted by the U.S. government  earlier this year for his alleged role in launching thousands of attacks across the world. Matveev, who resides in Saint Petersburg and is known by the aliases Wazawaka, m1x, Boriselcin, Uhodiransomwar, Orange, and waza, is alleged to have played a crucial part in the development and deployment of LockBit, Babuk, and Hive ransomware variants since at least June 2020. "Wazawaka and his team members prominently exhibit an insatiable greed for ransom payments, demonstrating a significant disregard for ethical values in their cyber operations," Swiss cybersecurity firm PRODAFT  said  in a comprehensive analysis shared with The Hacker News. "Employing tactics that involve intimidation through threats to leak sensitive files, engaging in dishonest practices, and persisting in retaining fil

Russian cyber espionage actors affiliated with the Federal Security Service (FSB) have been observed using a USB propagating worm called  LitterDrifter  in attacks targeting Ukrainian entities. Check Point, which  detailed  Gamaredon's (aka Aqua Blizzard, Iron Tilden, Primitive Bear, Shuckworm, and Winterflounder) latest tactics, branded the group as engaging in large-scale campaigns that are followed by "data collection efforts aimed at specific targets, whose selection is likely motivated by espionage goals." The LitterDrifter worm packs in two main features: automatically spreading the malware via connected USB drives as well as communicating with the threat actor's command-and-control (C&C) servers. It's also suspected to be an evolution of a PowerShell-based USB worm that was previously  disclosed  by Symantec in June 2023. Written in VBS, the spreader module is responsible for distributing the worm as a hidden file in a USB drive together with a deco

Russian threat actors have been possibly linked to what's been described as the "largest cyber attack against Danish critical infrastructure," in which 22 companies associated with the operation of the country's energy sector were targeted in May 2023.  "22 simultaneous, successful cyberattacks against Danish critical infrastructure are not commonplace," Denmark's SektorCERT  said  [PDF]. "The attackers knew in advance who they were going to target and got it right every time. Not once did a shot miss the target." The agency said it found evidence connecting one or more attacks to Russia's GRU military intelligence agency, which is also tracked under the name  Sandworm  and has a track record of orchestrating disruptive cyber assaults on industrial control systems. This assessment is based on artifacts communicating with IP addresses that have been traced to the hacking crew. The unprecedented and coordinated cyber attacks took place on

The Computer Emergency Response Team of Ukraine (CERT-UA) on Tuesday said it thwarted a cyber attack against an unnamed critical energy infrastructure facility in the country. The intrusion, per the agency, started with a phishing email containing a link to a malicious ZIP archive that activates the infection chain. "Visiting the link will download a ZIP archive containing three JPG images (decoys) and a BAT file 'weblinks.cmd' to the victim's computer," CERT-UA  said , attributing it to the Russian threat actor known as  APT28  (aka BlueDelta, Fancy Bear, Forest Blizzard, or FROZENLAKE). "When a CMD file is run, several decoy web pages will be opened, .bat and .vbs files will be created, and a VBS file will be launched, which in turn will execute the BAT file." The next phase of the attack involves running the "whoami" command on the compromised host and exfiltrating the information, alongside downloading the TOR hidden service to route malicious traffic. Persistence is achieve
