South Korea’s National Tax Service (NTS) accidentally exposed the mnemonic recovery phrase of a seized cryptocurrency wallet during a press release, leading to the theft of $4.8 million in crypto assets. The funds were stored in a Ledger cold wallet confiscated during raids on tax evaders. The recovery phrase, visible in photos released by the NTS, allowed attackers to transfer 4 million Pre-Retogeum (PRTG) tokens to a new address. The NTS has since removed the press release, and no investigation details have been disclosed. This incident highlights the critical importance of securing wallet seed phrases and the risks of exposing them publicly.

A security researcher disclosed a vulnerability in January 2026 that was used to build the Kimwolf botnet, the world's largest and most disruptive botnet. The botmaster, known as 'Dort,' has been linked to various cybercrime activities, including DDoS attacks, doxing, and email flooding. Dort has also been connected to the cybercrime group LAPSUS$ and has used multiple aliases such as 'CPacket' and 'M1ce.' The investigation reveals Dort's involvement in Minecraft cheating software and the development of tools for bypassing CAPTCHA services and creating temporary email addresses. Dort's real identity is suspected to be Jacob Butler, a resident of Ottawa, Canada.

Google API keys, previously considered harmless, now expose Gemini AI data due to a privilege escalation. Researchers found nearly 3,000 exposed keys across various sectors, including Google itself. These keys can authenticate to Gemini AI and access private data, potentially leading to significant financial losses for victims. New research from Truffle Security and Quokka has revealed the extent of this issue, with thousands of API keys embedded in client-side code and Android apps. Google has implemented measures to block leaked API keys and notify affected parties.

The U.S. Department of Defense (DoD) has designated Anthropic as a supply chain risk due to an impasse in negotiations over the use of its AI model, Claude. The Pentagon demands unrestricted use for military applications, including mass domestic surveillance and autonomous weapons, which Anthropic refuses. The DoD has ordered federal agencies and contractors to cease using Anthropic's technology, while Anthropic argues the designation is legally unsound and sets a dangerous precedent. Anthropic's stance aligns with broader concerns about AI ethics, as other tech companies and employees express support for its position.

The **ScarCruft (APT37) Ruby Jumper campaign**, first discovered in **December 2025** and detailed in **February 2026**, marks a **significant expansion of tactics** to breach air-gapped networks and abuse legitimate cloud services for command-and-control (C2). The campaign deploys a **multi-stage infection chain** beginning with a malicious LNK file that drops a decoy document (e.g., an Arabic translation of a North Korean article on the Palestine-Israel conflict), an executable payload (**RESTLEAF**), a PowerShell script, and a batch file. RESTLEAF leverages **Zoho WorkDrive for C2**—the first known instance of ScarCruft using this service—to fetch shellcode, which then deploys **SNAKEDROPPER**. This implant installs a Ruby runtime, establishes persistence via a **scheduled task (`rubyupdatecheck`)** that replaces the RubyGems default file `operating_system.rb`, and drops **THUMBSBD** and **VIRUSTASK**, both designed to **weaponize removable media (USB drives)** for lateral movement into air-gapped systems. THUMBSBD supports **keylogging, audio/video surveillance, and file exfiltration**, while also creating **hidden directories on USB drives** to stage operator commands or store execution output. VIRUSTASK focuses on **initial access propagation** via USB drives, replacing legitimate files with malicious shortcuts that execute the Ruby interpreter when opened. The campaign also delivers **FOOTWINE**, a reconnaissance tool disguised as an APK file that harvests documents and monitors removable drive activity, and **BLUELIGHT**, a backdoor that adapts its C2 mode based on network connectivity (direct cloud communication or USB-based staging). This follows earlier ScarCruft operations, including **ransomware attacks (July 2025)**, **Operation HanKook Phantom (September 2025)**, and the **Contagious Interview campaign (February 2026)**, which targeted developers via malicious repositories and job-themed lures. The Ruby Jumper campaign underscores ScarCruft’s **expanded focus on air-gapped infiltration**, combining **cloud abuse with physical media exploitation** to evade network isolation and achieve persistent surveillance with minimal forensic traces. Zscaler ThreatLabz confirmed the use of **six distinct tools** in this campaign, five of which were previously undocumented.

A coordinated international operation, Project Compass, has arrested 30 members of 'The Com,' a cybercrime group linked to ransomware attacks, extortion, violent activities, and the production of child sexual exploitation material (CSAM). The group, primarily composed of young individuals, has targeted high-profile entities and engaged in phishing, vishing, and SIM swapping. Project Compass, led by Europol's European Counter Terrorism Centre, involves multiple countries and aims to disrupt the group's operations and safeguard victims. The Com has been connected to Russian cybercriminal gangs and has expanded its activities to include physical violence, extremist links, and the exploitation of minors.

The U.S. Department of the Treasury has sanctioned several large cyber scam networks in Southeast Asia, primarily in Burma and Cambodia. These operations, which used forced labor and human trafficking, stole over $10 billion from Americans in 2024, a 66% increase from the previous year. The scams included romance baiting and fake cryptocurrency investments. The sanctions target individuals and entities linked to the Karen National Army (KNA) and various organized crime networks. The U.S. has established a new task force, the Scam Center Strike Force, to disrupt Chinese cryptocurrency scam networks. This task force, supported by the U.S. Attorney's Office, the Department of Justice, the FBI, and the Secret Service, has already seized over $401 million in cryptocurrency and filed forfeiture proceedings for an additional $80 million in stolen funds. The Treasury Department’s Office of Foreign Assets Control has imposed additional sanctions on the Democratic Karen Benevolent Army (DKBA) and related entities. In a recent development, the U.S. Department of Justice (DoJ) seized $61 million worth of Tether linked to pig butchering crypto scams. The confiscated funds were traced to cryptocurrency addresses used for laundering proceeds from cryptocurrency investment scams. Threat actors target individuals by cultivating romantic relationships on dating and social media messaging apps, coercing victims into investing in fraudulent platforms that display fake high returns. Scammers route stolen money through multiple wallets to hide its nature and source. Tether has frozen around $4.2 billion in assets linked to illicit activity, including $250 million related to scam networks since June 2025.

The compromised service provider is reportedly a Tunis-based customer support firm that suffered a Zendesk breach.

Yurii Nazarenko, a 27-year-old Ukrainian man, pleaded guilty to operating OnlyFake, an AI-powered platform that generated and sold over 10,000 fake identification documents. The service created realistic counterfeit passports, driver's licenses, and Social Security cards for customers worldwide, primarily to bypass Know Your Customer (KYC) verification requirements at banks and cryptocurrency exchanges. Nazarenko accepted cryptocurrency payments and attempted to cover his tracks by routing payments through multiple wallets. He was extradited from Romania in September 2025 and faces up to 15 years in prison, with sentencing scheduled for June 26, 2026.

The UK government's Vulnerability Monitoring Service (VMS) has reduced its backlog of critical vulnerabilities by 75% and decreased cyber-attack fix times by 87%. The service, introduced as part of the blueprint for modern digital government, uses commercial and proprietary scanning tools to identify and address DNS-related vulnerabilities in public sector internet-facing assets. The VMS scans 6000 UK public sector bodies, detecting around 1000 different types of cyber vulnerabilities. Additionally, the government launched the Cyber Profession initiative to attract and develop cyber talent.

Threat actors are distributing a Java-based remote access trojan (RAT) through trojanized gaming utilities spread via browsers and chat platforms. The malware uses PowerShell and living-off-the-land binaries (LOLBins) for stealthy execution and evades detection by deleting the initial downloader and configuring Microsoft Defender exclusions. The RAT connects to a command-and-control (C2) server for data exfiltration and additional payload deployment. The disclosure coincides with the emergence of Steaelite, a new Windows RAT malware family advertised on criminal forums, which combines data theft and ransomware capabilities in a single web panel. Additionally, two new RAT families, DesckVB RAT and KazakRAT, have been discovered, enabling comprehensive remote control over infected hosts.

Meta has filed lawsuits against advertisers based in Brazil, China, and Vietnam for engaging in deceptive advertising practices, including celeb-bait scams and cloaking techniques. The company has also issued cease and desist letters to marketing consultants offering services to bypass ad policy enforcement systems. The scams involved misusing celebrity images to promote fraudulent healthcare products, investment schemes, and other malicious activities. Meta has taken steps to suspend payment methods, disable related accounts, and block domain names used in these scams. The company has also developed protections for celebrities whose images are frequently used in such schemes. Additionally, Meta's actions come in the wake of reports indicating a significant portion of its ad sales in China were linked to scams, illegal gambling, and other banned content.

Marquis Software Solutions has **filed a lawsuit** against SonicWall, alleging **gross negligence and misrepresentation** in the handling of its MySonicWall cloud backup breach, which directly enabled a **ransomware attack** disrupting **780,000+ individuals** across 700+ U.S. banks and credit unions in August 2025. The lawsuit reveals that SonicWall introduced a **security gap via an API code change in February 2025**, allowing unauthorized access to firewall configuration backups—including AES-256-encrypted credentials and MFA scratch codes. Marquis, whose firewall was fully patched and MFA-enabled, confirms attackers exploited this stolen data to bypass defenses, contradicting earlier assumptions about unpatched devices. The breach exposed **personal and financial data** of Marquis’s clients, triggering **over 36 consumer class-action lawsuits** and prompting Marquis to seek damages, indemnification, and legal fees. The SonicWall incident began as a targeted compromise of its MySonicWall portal, initially reported in September 2025 as affecting fewer than 5% of customers but later revised to confirm **all cloud backup users** were impacted. Stolen configuration files—containing credentials, network topology, and encrypted secrets—fueled follow-on attacks, including the **Marquis ransomware breach** (January 2026 disclosure) and Akira ransomware campaigns abusing OTP seeds to bypass MFA. SonicWall collaborated with Mandiant to attribute the breach to **state-sponsored actors** and released remediation tools, but the Marquis lawsuit underscores the **long-tail risks** of exposed backup data, even post-containment. Over **950 unpatched SMA1000 appliances** remain exposed online, while CISA and SonicWall urge firmware updates, credential resets, and MFA enforcement. Legal experts note the case could set a precedent for **vendor liability**, as enterprises increasingly sue cybersecurity providers for contribution or negligence. The lawsuit also highlights the need for robust vendor due diligence and SLAs that address worst-case scenarios, including vendor-caused breaches. SonicWall may face further legal challenges from Marquis’s clients or regulatory actions if found liable for the downstream impact.

The Aeternum botnet loader has shifted its command-and-control (C2) operations to the Polygon blockchain, eliminating traditional central servers. This move makes it harder for authorities and security firms to disrupt the botnet by seizing infrastructure. The botnet uses smart contracts on the blockchain to issue commands, which are publicly recorded and immutable. Aeternum is a native C++ loader available in x32 and x64 builds. Operators manage infections via a web dashboard that allows them to select a smart contract, choose a command type, and specify a payload URL. Commands are written to the blockchain as transactions and are accessible to bots querying over 50 remote procedure call endpoints. The botnet's use of blockchain-based C2 complicates traditional takedown strategies, as there is no central infrastructure to seize. Commands stored on-chain are permanent and globally accessible, making proactive DDoS mitigation more critical. The threat actor LenAI has attempted to sell the entire Aeternum toolkit for $10,000, claiming a lack of time for support and involvement in another project. LenAI is also behind a second crimeware solution called ErrTraffic.

Trend Micro has disclosed and patched two critical vulnerabilities, CVE-2025-71210 and CVE-2025-71211, in its on-premise Apex One Management Console.

Successful exploitation could lead to full router takeover. The issue impacts versions before 25.4R1-S1-EVO and 25.4R2-EVO, with fixes available in newer versions. Juniper Networks has not observed active exploitation as of the advisory's publication.

Olympique de Marseille, a French football club, confirmed an attempted cyberattack after a threat actor claimed to have breached the club's systems earlier in February 2026. The attacker leaked a sample of allegedly stolen data, including information on 400,000 individuals, on a hacking forum. The club reassured that no banking details or passwords were compromised and advised fans to remain vigilant against phishing attempts. The threat actor claims the stolen database contains names, addresses, email addresses, mobile phone numbers, and order information, as well as details on 2,050 Drupal CMS accounts, including 34 staff members and 1,770 contributors and moderators. The club has reported the incident to the French data protection authority (CNIL) and filed a complaint.

A previously undocumented threat activity cluster, tracked as UAT-10027, has been targeting U.S. education and healthcare sectors since at least December 2025. The campaign delivers a new backdoor named Dohdoor, which uses DNS-over-HTTPS (DoH) for command-and-control (C2) communications. The initial access vector is suspected to involve social engineering phishing techniques, leading to the execution of a PowerShell script that downloads and runs a malicious DLL. The backdoor is launched via DLL side-loading using legitimate Windows executables. The threat actor hides C2 servers behind Cloudflare infrastructure to evade detection. Dohdoor also unhooks system calls to bypass endpoint detection and response (EDR) solutions. While there are tactical similarities to Lazarus Group malware, the victimology differs from typical Lazarus targets.
