🔒 Check Point disclosed an advanced persistent threat dubbed Silver Dragon, active since mid-2024 and assessed to operate under the APT41 umbrella. The group gains access via vulnerable public servers and phishing, deploying loaders such as MonikerLoader and the C++ BamboLoader to stage Cobalt Strike beacons. Post-exploitation tools include screen capture, SSH utilities, and a Google Drive backdoor used for file-based C2.

⚠ Operation Epic Fury — the US administration's sustained kinetic pressure on core Iranian regime assets — creates an immediate layer of operational risk for multinationals with people, infrastructure, or supply dependencies in the Middle East and beyond. Briefings from Washington offer situational context but do not capture the operational exposure that surfaces as hostilities begin. CISOs, CSOs, and chief risk officers must validate assumptions, set evacuation and wellness protocols, and apply travel thresholds. Cyber posture should be hardened with accelerated patching, edge device controls, and OT segmentation to reduce attack surface.

⚠️ Beginning Feb. 28, 2026, Unit 42 observed a rapid escalation in cyber activity tied to Iran following joint U.S.–Israeli strikes, coinciding with an internal internet outage that reduced connectivity in Iran to 1–4%. That loss likely constrains coordinated state-aligned campaigns from inside Iran while enabling decentralized and geographically dispersed actors to increase disruptive operations. Unit 42 identified a phishing campaign using a malicious replica of the Israeli Home Front Command RedAlert APK and tracked about 60 active hacktivist groups claiming DDoS, wiper, and hack-and-leak operations. Organizations should prioritize multi-layered defenses, offline backups, strict out-of-band verification, patching, monitoring, and incident response preparedness; Palo Alto Networks and Unit 42 offer protections and services to assist.

⚠ John Hultquist, chief analyst of Google’s Threat Intelligence Group, warned that Iran will "absolutely" respond to recent US and Israeli air strikes with cyber-attacks targeting a broad array of organisations across the Middle East and beyond. He said the focus will shift from well-defended states like Israel to nations with less mature security, expanding the global attack surface. Hultquist highlighted the blurred lines between state actors, criminal groups and hacktivist fronts, noting the likely use of ransomware and proxy operations by the IRGC to obfuscate attribution. The UK’s NCSC has advised organisations with Middle East ties to urgently review and strengthen their cybersecurity posture.

🌐 A sharp escalation in the Middle East has entered a hybrid phase combining military strikes with large-scale cyber operations following joint Israeli–US strikes on Iran on 28 February 2026. CloudSek reported a sweeping cyber campaign that reduced Iran's internet to roughly 4% of normal capacity, disrupting government services, media and parts of energy and aviation. Security firm Halcyon warns of rising DDoS, hacktivist and ransomware activity and urges organisations to increase monitoring, enforce multi-factor authentication and maintain offline backups against supply-chain and regional spillover risks.

🔍 Iran’s cyber ecosystem combines state-aligned clusters, deniable operators, and hacktivists linked to IRGC and MOIS. These actors pursue espionage, disruption and destructive operations—DDoS, pseudo-ransomware, and wipers—often paired with information operations and coordinated amplification. Activity is intensifying amid the current crisis and is expected to broaden across the Middle East, the United States, and other regions.

🔒Iran's January 2026 communications blackout was a comprehensive shutdown that disabled mobile networks, landlines, and even Starlink, extending beyond conventional URL blocking to dismantle both physical and logical connectivity. The regime is formalizing a two-tiered model—white SIM cards and data-center whitelists—that preserves full access for officials while isolating ordinary citizens. By removing social features and disabling local chat channels, the state aims to atomize the population and prevent real-time coordination. The author urges policy and technical measures—such as expanded humanitarian licensing and D2C satellite access—to give repressed populations resilient means of connectivity.

🔐 This practical Q&A guide helps leaders translate evolving threats into actionable resilience measures. It highlights why national cyber security urgency has increased as adversaries shift from theft to persistent, disruptive positioning that can affect fuel, hospitals, elections, markets, and public trust. The brief recommends adoption of NIST frameworks, Zero Trust principles, and AI governance to mitigate cloud, OT, and supply chain risks. Leaders receive concise operational steps to align policy, technology, and cross‑sector coordination.

🛡️ Google disrupted a China-linked espionage group that repurposed Google Sheets as a covert command-and-control channel to manage a custom backdoor tracked as UNC2814 and named GRIDTIDE. The backdoor abused legitimate Sheets API calls to send commands, retrieve stolen data, poll spreadsheets frequently, and wipe rows to erase traces. Mandiant flagged unusual activity on a CentOS server, leading to discovery of intrusions at 53 organizations across 42 countries focused on telecoms and government systems. Google terminated attacker Cloud projects, revoked API access, sinkholed domains, and published IOCs.

🛡️ Google Threat Intelligence Group, Mandiant, and partners executed a coordinated disruption against a global espionage campaign attributed to UNC2814 that abused cloud services for covert command and control. Investigators identified a novel C-based backdoor called GRIDTIDE that uses Google Sheets APIs as a high-availability C2 channel, protected by an AES-128-CBC key and service account credentials. Actions included terminating attacker-controlled Google Cloud projects, disabling accounts and Sheets API access, sinkholing infrastructure, and publishing IOCs and detection guidance to support defenders.

🔒 The U.S. Treasury Department's Office of Foreign Assets Control designated Matrix LLC (doing business as Operation Zero) and its owner, Sergey Zelenyuk, under the Protecting American Intellectual Property Act, marking the first use of that law. The move coincided with the sentencing of former L3Harris manager Peter Williams, who was given 87 months for stealing eight zero‑day exploits and selling them to Operation Zero for about $1.3 million in cryptocurrency. OFAC also named related companies and individuals, including a UAE front company and a suspected Trickbot affiliate, freezing U.S. assets and warning of potential secondary sanctions for U.S. persons who transact with the designated parties.

🔒 Peter Williams, a 39-year-old former senior employee at L3Harris, was sentenced to just over seven years in prison after pleading guilty to selling eight zero-day exploits to the Russian exploit broker Operation Zero. Prosecutors say he received up to $4 million in cryptocurrency and has been ordered to forfeit proceeds, including properties and luxury items. The theft, which occurred between 2022 and 2025, targeted tools intended for sale only to the U.S. government and select allies and prompted criminal charges and sanctions.

🛡️ AWS security researchers report a Russian-speaking attacker compromised more than 600 FortiGate firewalls between January 11 and February 18, 2026, by exploiting weak or default passwords rather than product vulnerabilities. The actor used a Google Gemini-based AI tool to pivot to additional hosts and deployed reconnaissance tools written in Go and Python. Analysts found clear signs of AI-assisted code generation. Experts urge strong passwords and enabling MFA.

🛡️ Acronis Threat Research Unit disclosed CRESCENTHARVEST, a campaign observed after January 9 that targets Farsi-speaking supporters of Iran's protests with a remote access trojan and information stealer. Attackers lure victims with protest-themed archives and double-extension .LNK shortcuts that run PowerShell to fetch a secondary ZIP while opening benign media. The payload sideloads DLLs via a Google-signed software_reporter_tool.exe, extracts Chrome app-bound keys, harvests browser and Telegram data, logs keystrokes, and communicates with a WinHTTP C2 at servicelog-information[.]com.

🔐 At the Munich Cybersecurity Conference (MCSC) 2026, representatives from the White House, FBI, Europol, OECD, BSI, BND, the European Commission and Japan's National Cybersecurity Office convened to discuss the rising global cyber threat environment. Speakers emphasized the need for stronger public-private cooperation and the industrialization of cybersecurity to better protect critical digital infrastructure. Panelists warned that geopolitical tensions - notably involving North Korea, China and Russia - and transnational cybercrime demand coordinated international responses.

⚠️ Google Threat Intelligence Group (GTIG) attributes a previously undocumented actor, likely linked to Russian intelligence, to campaigns using CANFAIL against Ukrainian defense, military, government, and energy organizations. The actor has expanded interest to aerospace, defense-adjacent manufacturing, nuclear and chemical research, and humanitarian groups, often impersonating Ukrainian and Romanian energy firms in phishing. Operators used LLMs to produce reconnaissance and social-engineering lures, embedding Google Drive links to RAR archives that deliver obfuscated JavaScript which spawns PowerShell memory-only droppers. GTIG links this activity to the PhantomCaptcha campaign disclosed by SentinelOne SentinelLABS in October 2025.

🔎 Google Threat Intelligence Group (GTIG) warns that state-sponsored actors from China, Iran, Russia, and North Korea are conducting sustained cyber operations against the defense industrial base (DIB). GTIG highlights four themes: targeting battlefield technologies like drones, exploiting hiring and personnel processes, leveraging edge devices for initial access, and capitalizing on manufacturing supply chain breaches. Observed tactics include bespoke malware families, abuse of secure messaging linking, careful endpoint-evasion techniques, and use of relay networks to complicate detection and attribution.

🔍 Google’s Threat Intelligence Group and DeepMind found that government-backed APTs increasingly use Gemini and other generative AI for reconnaissance, target profiling and sophisticated social engineering. Observed actors include Iran’s APT42 and North Korea’s UNC2970 using models to harvest email addresses and synthesize OSINT, while TEMP.Hex and APT31 applied AI for vulnerability research and automated testing. The report also details a rise in model extraction attempts, an underground jailbreak ecosystem (notably the Xanthorox toolkit), abuse of public sharing to host malicious instructions, and cases such as Honestcue leveraging Gemini APIs to generate in-memory malicious code; Google has disabled associated assets and warns of intellectual-property theft risks.

🛡️ Google Threat Intelligence Group warns state-backed actors are abusing Gemini across the full attack lifecycle, from reconnaissance and phishing-lure generation to C2 development and data exfiltration. Groups linked to China, Iran, North Korea, and Russia used the model for target profiling, code generation, translation, vulnerability testing, and troubleshooting. Google says it has disabled abusive accounts and implemented targeted classifier defenses to make misuse harder.

🔍 DPRK-linked IT operatives are escalating a long-running fraud by applying to remote positions using genuine LinkedIn profiles they impersonate, often including verified workplace emails and identity badges. Security Alliance and other researchers warn this helps attackers bypass basic vetting and gain administrative access to sensitive codebases. Parallel social engineering
