🔒 Broadcom's Symantec and Carbon Black Threat Hunter Team found an Iran-linked group, MuddyWater, embedded in networks of U.S. banks, airports, a Canadian non‑profit, and an Israeli software supplier. Researchers uncovered a novel Deno-based backdoor named Dindoor and a Python backdoor, Fakeset, whose signing certificate ties it to prior MuddyWater tools. An attempted Rclone exfiltration to a Wasabi bucket was observed. Vendors recommend bolstering monitoring, enforcing phishing-resistant MFA, segmenting networks, and reducing internet exposure of critical systems.

🔒 Derrick Van Yeboah, a 40-year-old Ghanaian national, pleaded guilty to conspiracy to commit wire fraud for his role in a transnational fraud ring that prosecutors say stole more than $100 million through romance scams and business email compromise attacks. Extradited to the U.S. in August 2025, he agreed to pay over $10 million in restitution and faces up to 20 years in prison. Prosecutors say he personally carried out many romance scams that targeted vulnerable Americans and worked with U.S. and West African accomplices to launder proceeds.

🚨 The U.S. Federal Bureau of Investigation confirmed it is investigating a breach that affected systems used to manage surveillance and court-authorized wiretap warrants. The agency said it identified and addressed suspicious activity on FBI networks and has leveraged technical capabilities to respond, but declined to provide details on scope or impact. CNN reported an anonymous source saying the intrusion affected systems supporting wiretapping and foreign surveillance. Security observers note similarities with prior activity attributed to the state-linked group Salt Typhoon.

🛰️ Cisco Talos says a China-linked APT tracked as UAT-9244 has been targeting critical South American telecommunications since 2024, deploying three undocumented implants: TernDoor for Windows, PeerTime for Linux, and BruteEntry on edge devices. TernDoor uses DLL side-loading via wsprint.exe and a rogue BugSplatRc64.dll to execute payloads in memory and embed a driver to control processes. PeerTime is a multi-architecture P2P backdoor (ARM, AARCH64, PPC, MIPS) that uses BitTorrent for C2 and comes in C/C++ and Rust builds, while BruteEntry turns compromised edge hardware into brute-force proxy nodes targeting Postgres, SSH and Tomcat.

⚠️ Microsoft disclosed a ClickFix social engineering campaign observed in February 2026 that leverages the Windows Terminal app to execute malicious commands and deliver the Lumma Stealer. Attackers instruct targets to open Windows Terminal (wt.exe) via Windows+X → I and paste hex‑encoded, XOR‑compressed commands from fake CAPTCHA or troubleshooting pages, avoiding Run‑dialog detection. The decoded chain downloads a ZIP and a renamed 7‑Zip binary to extract payloads, sets persistence, configures Defender exclusions, and injects the stealer into browser processes to harvest stored credentials.

🔒 Law enforcement across 14 countries seized the LeakBase cyberforum, taking its database and two domains and targeting roughly 142,000 users. Authorities executed around 100 coordinated actions beginning March 3, including arrests, search warrants, and interviews in multiple jurisdictions. The captured data reportedly contained credential pairs, payment card details, bank account information, and other sensitive personally identifiable and business data. Investigators say the technical seizure unmasked users who believed they were operating anonymously and that authorities delivered prevention messages while continuing to trace digital trails.

🛡️ Cisco Talos researchers report that a China-linked APT cluster tracked as UAT-9244 has been targeting telecommunication providers in South America since 2024, compromising Windows, Linux, and network-edge devices. The campaign uses three previously undocumented malware families: TernDoor (Windows backdoor), PeerTime (ELF BitTorrent-based Linux backdoor), and BruteEntry (brute-force scanner and proxy builder). Talos published a technical report with capabilities, deployment methods, persistence techniques, and IoCs for detection and mitigation.

⚠️ Researchers at Huntress found that Microsoft Bing’s AI-enhanced search suggested malicious GitHub repositories posing as installers for OpenClaw, instructing users to run commands that deployed information-stealing and proxy malware. The fake repos were tied to newly created GitHub accounts and mimicked legitimate projects to appear trustworthy. Windows and macOS installers delivered Rust-based loaders, the Atomic Stealer family, Vidar, and a GhostSocks backconnect proxy. Huntress reported the repositories to GitHub and recommends using official project portals and bookmarked download sources rather than search results.

🛡️ The Wikimedia Foundation experienced a security incident after a self‑propagating JavaScript worm began vandalizing pages and modifying user scripts across multiple wikis. The malicious code, traced to a user script User:Ololoshka562/test.js uploaded in March 2024, injected loaders into both user-level and global MediaWiki:Common.js. Engineers temporarily restricted editing, reverted malicious edits, rolled back affected user scripts, and removed the injected code, but a full post‑incident report has not yet been published.

🔒 John Daghita, a U.S. government contractor and son of CMDSS's CEO, was arrested on Saint Martin after a joint operation by the FBI and France's elite Gendarmerie unit. He is accused of stealing more than $46 million in cryptocurrency seized and managed by the U.S. Marshals Service, including funds tied to the 2016 Bitfinex hack. Authorities seized cash, hard drives, and security keys, and investigators say public blockchain analysis played a key role in identifying him.

🎯Multiple outlets report that Israel hacked Iranian traffic cameras and used the access to facilitate the targeting and killing of Iranian leaders. The New York Times details the broader intelligence operation and strategic context. The revelations raise questions about the use of civilian infrastructure in lethal operations and potential international legal and escalation risks. Security experts note that camera networks, often insecure and internet-connected, create an attack surface exploited by state actors.

🔒 Microsoft Defender investigated malicious Chromium browser extensions that impersonated legitimate AI assistant tools to collect LLM chat histories and browsing telemetry. Distributed via the Chrome Web Store and compatible with both Google Chrome and Microsoft Edge, the extensions captured full URLs and chat snippets from platforms such as ChatGPT and DeepSeek, reaching roughly 900,000 installs and activity in over 20,000 enterprise tenants. Microsoft provides detections, hunting queries, and mitigation guidance to contain exposure and remediate affected devices.

🔒 Europol coordinated a multi-country operation with Amsterdam police that shut down Leakbase, described as one of the world's largest marketplaces for stolen data. Authorities seized the platform's servers in Amsterdam and said Leakbase had about 142,000 registered users worldwide. Investigators in 14 countries executed around 100 raids, targeting roughly 37 main users. The probe began in the Netherlands in 2023 and involved close cooperation with the U.S. FBI.

🚨 Spanish and Ukrainian authorities dismantled a criminal network that exploited war-displaced Ukrainian women to run an automated online gambling and money-laundering scheme. The group financed victims' travel to Spain, coerced them into opening bank accounts and credit cards, then seized control to feed bot-driven low-odds bets. Investigators say the operation used identities from over 5,000 people across 17 nationalities and laundered an estimated €4.75 million. Authorities arrested 12 suspects, executed searches in Spain and Ukraine, and seized devices, bots, SIMs, vehicles and frozen properties.

🛡️ Zscaler ThreatLabz reported in January 2026 that a suspected Iran-nexus cluster dubbed Dust Specter has targeted Iraqi government officials by impersonating the Ministry of Foreign Affairs to deliver novel malware families — SPLITDROP, TWINTASK, TWINTALK, and GHOSTFORM. The campaign uses two infection chains: a password-protected RAR containing a .NET dropper that sideloads DLLs and a consolidated in-memory binary that avoids disk writes. Operators staged payloads on compromised Iraqi infrastructure and employed geofencing, User-Agent checks, randomized C2 URIs with checksums, and execution delays; Zscaler also notes code artifacts suggesting possible use of generative AI.

🔒 Amsterdam police, working with Europol and international partners, have shut down LeakBase, a major online marketplace for stolen data whose servers were located in Amsterdam. The platform had about 142,000 registered users and has been seized as part of a joint operation involving investigators from 14 countries and the FBI. Authorities conducted around 100 targeted operations aimed at 37 primary users. The site now displays a police notice warning that trading stolen data is a criminal offense.

📱 The Iranian prayer-timing app BadeSaba Calendar — installed by over five million users from the Google Play Store — delivered a rapid series of push notifications shortly after a set of explosions, beginning at 9:52 a.m. Tehran time. The alerts, starting with the phrase 'Help has arrived', reached users over roughly 30 minutes. No one has claimed responsibility; analysts say the speed and scale point to a likely state operation, with the US and Israel named as plausible actors.

🚨 Cisco Talos discloses UAT-9244, a China‑nexus APT active since 2024 that has targeted South American telecommunications providers and deployed three implants: TernDoor, PeerTime, and BruteEntry. The actor compromises Windows and multi‑architecture Linux/embedded devices using DLL side‑loading, BitTorrent-based P2P C2, and large-scale brute‑forcing via converted edge devices. Talos provides IOCs, detection signatures, and mitigations to help defenders identify and disrupt this campaign.

🐾 ClearSky reports a Russian-linked campaign targeting Ukrainian entities that deploys a .NET loader named BadPaw and a backdoor called MeowMeow. The attack begins with a phishing message that lures victims to download a ZIP archive containing an HTA decoy presenting a Ukrainian border-crossing appeal while executing hidden stages. The HTA extracts a VBScript and a PNG-embedded loader, establishes persistence via a scheduled task, and orchestrates retrieval of the MeowMeow backdoor from a remote C2 server. Researchers attribute the operation to APT28 with moderate confidence based on targeting, lures, and tradecraft overlaps.

🔒 Europol and international partners have taken down LeakBase, an English-language forum that trafficked stolen credentials and stealer logs, seizing two domains and the site's customer database. Coordinated actions on March 3 included arrests, house searches and interviews across the US, Australia, Belgium, Poland, Portugal, Romania, Spain and the UK. Europol said 37 of the forum’s most active users were targeted and vowed to continue tracing offenders as part of Operation Leak.
