A newly identified Russian cyber-espionage group, known as Laundry Bear by Dutch intelligence and Void Blizzard by Microsoft, has been actively targeting Western organizations since at least April 2024. This group is believed to be backed by the Russian government and is primarily focused on gathering intelligence to support Russian strategic interests. Laundry Bear's targets include government entities, defense contractors, aerospace firms, and high-tech businesses in Europe and North America, particularly those supporting Ukraine. The group's activities suggest an interest in sensitive information related to military goods, weapons deliveries, and advanced technologies that are difficult for Russia to acquire due to Western sanctions.
The primary objective of Laundry Bear is to steal sensitive emails and files from compromised systems. They achieve this by targeting cloud-based email environments, specifically Microsoft Exchange. The group employs a range of techniques, including pass-the-cookie attacks, password spraying, and spear phishing aimed at credential theft. Notably, the Dutch intelligence services identified Laundry Bear during an investigation into a credential-stealing attack against the Dutch National Police in September 2024. During this attack, Laundry Bear gained access to an account belonging to a Dutch police employee by using a stolen session cookie to obtain work-related contact information of other police employees.
Microsoft has also observed Laundry Bear targeting critical sectors such as government, defense, transportation, media, NGOs, and healthcare, with a focus on organizations in Europe, North America, NATO member states, and Ukraine. The group frequently gains access by using stolen credentials, likely purchased from online marketplaces. Despite employing relatively simple attack methods and readily available tools, Laundry Bear has achieved a high success rate due to quick-paced cyber operations and efficient automation. Microsoft recommends organizations implement robust security measures to defend against such threats.

A joint cybersecurity advisory has been issued by intelligence and cybersecurity agencies from multiple Western nations, including the United States, the United Kingdom, Germany, and France, warning of an aggressive cyber espionage campaign orchestrated by a Russian military cyber unit. The advisory directly implicates the Russian General Staff Main Intelligence Directorate (GRU) unit 26165, also known as APT28, Fancy Bear, and Forest Blizzard. This group has been actively targeting logistics and technology companies that are involved in providing aid to Ukraine. Their operations, ongoing for over two years, involve infiltrating networks to spy on arms shipments and logistics operations.
The GRU hackers are targeting a range of entities critical to the supply chain supporting Ukraine, including defense contractors, transport hubs like airports and ports, air traffic control systems, maritime operators, and IT service providers. Affected countries include the United States, Germany, Poland, France, Romania, Ukraine, the Netherlands, and others. The attackers not only infiltrate the main target company but also go after partners and connected firms, abusing trust relationships to spread deeper. In one instance, hackers stole credentials, gaining access to sensitive information on shipments, such as train schedules and shipping manifests.
The Russian hackers are employing a mix of both established and novel tactics to breach security. These tactics include credential guessing, brute-force attacks, and spearphishing emails disguised as legitimate login pages from Western email platforms. The GRU unit is also known for exploiting IP cameras in Ukraine and bordering NATO countries, likely to gather intelligence and monitor activities. Cybersecurity agencies urge logistics entities and technology companies to enhance monitoring, proactively hunt for known tactics and indicators of compromise, and fortify their network defenses, presuming they are targets.

British retailer giant Marks & Spencer (M&S) is facing a major financial impact following a recent cyberattack, with potential profit losses estimated at £300 million, equivalent to $402 million. The attack has caused widespread operational and sales disruptions, particularly affecting the company's online retail systems. According to a recent filing with the London Stock Exchange, M&S anticipates these disruptions to continue until at least July, impacting its fiscal year 2025/26 profits.
The cyberattack has significantly impacted M&S’s online sales channels, forcing the company to temporarily halt online shopping in its Fashion, Home & Beauty divisions. This downtime has led to substantial revenue loss, despite the resilience of its physical stores. The company has also faced increased logistics and waste management costs as it reverted to manual processes. CEO Stuart Machin acknowledged the challenging situation but expressed confidence in the company's recovery, emphasizing a focus on restoring systems and accelerating technical transformation.
M&S is actively implementing strategies to mitigate the financial repercussions, including cost management, insurance claims, and strategic trading actions. The retailer is reportedly preparing to claim up to £100 million from its cyber insurance policy to offset some of the losses. The company views this crisis as an opportunity to expedite its technical transformation, although specific details of this transformation have not yet been disclosed. The costs related to the attack itself and technical recovery are expected to be communicated at a later date as an adjustment item.

Security researchers are raising alarms about the open-source library 'easyjson,' a Golang package used extensively across cloud-native technologies. A new investigation by cybersecurity firm Hunted Labs has revealed that easyjson is maintained and controlled by developers associated with VK Group, a major Russian internet conglomerate based in Moscow. VK Group's ties to the Kremlin, including its leadership being under U.S. and E.U. sanctions, have ignited concerns about potential supply chain risks for organizations relying on this library. Easyjson is used by the US government and American companies.
The 'easyjson' library is deeply embedded in the software ecosystem, particularly in cloud-native applications, distributed systems, and real-time analytics platforms. It's found to be widely used in projects like Helm, Istio, Kubernetes, ArgoCD, Grafana, Sigstore, and across many US Government and Fortune 500 organizations. This widespread integration makes it difficult to monitor, remove, or replace, according to Hunted Labs. The firm's report warns that "Any compromise of a serializer is extremely dangerous because they are: invisible, deeply integrated, hard to remove, and trusted by default.”
Researchers fear that Russia could alter easyjson to steal data or otherwise be abused. Hunted Labs outlines alarming possibilities if easyjson were to be compromised or weaponized, including supply chain backdoors enabling mass compromise, remote code execution via crafted JSON inputs, espionage and covert data exfiltration, and even kill switch activation across critical systems. As Hayden Smith, a cofounder at Hunted Labs, stated, the package is "basically a linchpin for the cloud native ecosystem, that’s maintained by a group of individuals based in Moscow belonging to an organization that has this suspicious history."

The Hive0117 group, linked to DarkWatchman, is reportedly targeting Russian critical infrastructure in a broad cyber campaign. According to F6 Threat Intelligence, the group is conducting a large-scale phishing campaign aimed at Russian companies across various industries, including media, tourism, finance, insurance, manufacturing, retail, energy, telecommunications, transport, and biotechnology. The attacks, which have been ongoing since February 2022, involve mass mailings disguised as legitimate organizations, using registered infrastructure for managing domains and often reusing domains.
The malicious emails contain password-protected archives which, when opened, trigger a chain reaction leading to system infection by a modified version of the DarkWatchman VPO. This variant is designed to operate stealthily and evade detection by traditional security tools. Analysis reveals that the domains used in these attacks share registration data with domains previously used by the group in 2023, indicating a persistent and evolving threat. The DarkWatchman malware itself is a JavaScript-based remote access trojan capable of keylogging, collecting system information, and deploying secondary payloads.
The financially motivated Hive0117 group has previously targeted users in Lithuania, Estonia, and Russia in sectors like telecom, electronics, and industry. Past campaigns have also used courier delivery-themed lures to target Russian banks, retailers, telecom operators, agro-industrial enterprises, fuel and energy companies, logistics businesses, and IT firms. The DarkWatchman malware's fileless nature, use of JavaScript and a C#-based keylogger, and ability to remove traces of its existence highlight its sophisticated capabilities, posing a significant risk to targeted organizations.

France has officially accused the APT28 hacking group, linked to Russia's military intelligence service (GRU), of orchestrating a series of cyberattacks against French institutions over the past four years. The French foreign ministry condemned these actions "in the strongest possible terms," highlighting the targeting or breaching of a dozen French entities. The attacks have affected a range of organizations, including public services, private companies, and even a sports organization involved in preparations for the 2024 Olympic Games which was hosted in France.
France views these cyber operations as "unacceptable and unworthy" of a permanent member of the UN Security Council, asserting that Russia has violated international norms of responsible behavior in cyberspace. The ministry emphasized that such destabilizing activities undermine the integrity of international relations and security. This public attribution of the attacks to the GRU signifies a firm stance against Russia's malicious cyber activities and a commitment to defending French interests in the digital realm.
France, alongside its partners, is determined to anticipate, deter, and respond to Russia’s malicious cyber behavior, employing all available means. The French foreign ministry's statement also referenced past incidents, including the 2015 sabotage of TV5Monde and attempts to disrupt the 2017 presidential election, underscoring a pattern of APT28's disruptive activities targeting French interests. The French national agency for information systems security (ANSSI) has released a report on the threat linked to APT28 in order to prevent future attacks.

The Russia-linked cyber espionage group Shuckworm, also known as Gamaredon or Armageddon, is actively targeting a Western country's military mission based in Ukraine. The campaign, which began in February 2025 and continued through March, involves the deployment of an updated, PowerShell-based version of its GammaSteel infostealer malware. This latest wave of activity underscores Shuckworm's persistent focus on Ukrainian targets, with the group believed to be operating on behalf of Russia's Federal Security Service (FSB). They have historically concentrated their efforts on government, military, and law enforcement targets in Ukraine.
The initial infection vector in this campaign appears to be infected removable drives. Evidence from the Windows Registry's UserAssist key suggests that the infection was triggered from such an external drive. The attack chain is multi-staged and designed to minimize detection. It involves the execution of obfuscated VBScript and PowerShell scripts stored in the registry. This shift towards PowerShell-based tools allows Shuckworm to improve obfuscation and store scripts directly within the Windows Registry, making file-based detection more challenging.
GammaSteel, the malware deployed in this campaign, now has enhanced reconnaissance features. It is capable of capturing screenshots, gathering system information, and enumerating desktop contents and user documents. The malware targets specific file types such as documents, spreadsheets, and PDFs. Shuckworm's exfiltration methods have also become more sophisticated, utilizing PowerShell web requests or cURL with Tor proxies to extract sensitive data stealthily. This campaign demonstrates an increase in sophistication for Shuckworm, with the group leveraging legitimate web services to lower the risk of detection.

Russia-aligned cyber threat groups UAC-0050 and UAC-0006 are actively using bulletproof hosting infrastructures to conduct cyberattacks globally. These networks, often obscured by offshore shell companies, provide a shield for malicious activities including espionage, financial theft, and psychological operations. Intrinsec analysts have uncovered campaigns blending cyber espionage, financial theft, and psychological warfare, primarily targeting Ukraine and its allies with tactics like bomb threats and fake banking transactions.
These threat groups heavily rely on bulletproof hosting providers to evade detection. Entities like Global Connectivity Solutions LLP and Railnet LLC act as legal fronts, using offshore shell companies in jurisdictions like Seychelles to make attribution and legal action difficult. This infrastructure also supports ransomware groups like Black Basta and RansomHub and involves frequent IP migrations across autonomous systems, further complicating efforts to block malicious activities. UAC-0050 has also engaged in psychological operations, such as sending bomb threats to Ukrainian institutions under the guise of the "Fire Cells Group."
