🔒 CloudSEK reports that Iran-linked APT MuddyWater has deployed a Rust-based implant dubbed RustyWater in a spear-phishing campaign targeting diplomatic, maritime, financial, and telecom entities across Israel and the Middle East. The campaign relies on icon-spoofed executables delivered in ZIP archives that display decoy PDFs while executing loaders which establish persistence and fetch the Rust payload. RustyWater implements anti-analysis checks, string obfuscation, randomized callbacks and standard RAT functions including file enumeration, command execution and data exfiltration, while using C2 domains that mimic legitimate services.

🛡️ CloudSEK researchers report that the Iran-linked actor MuddyWater has distributed a new Rust-based remote access tool codenamed RustyWater via spear-phishing emails containing malicious Microsoft Word documents. The lure employs icon spoofing and a VBA macro that drops a Rust implant capable of asynchronous C2, anti-analysis, registry persistence, and modular expansion. Tracked also as Archer RAT or RUSTRIC, the implant contacts a hardcoded C2 (nomercys.it[.]com) to perform file operations and execute commands. Seqrite Labs linked RUSTRIC to recent activity against IT firms, MSPs and software companies in Israel.

🔍 SafeBreach has linked renewed operations to the Iranian APT known as Infy (Prince of Persia), revealing updated Foudre downloader and Tonnerre implants active across Iran, Iraq, Turkey, India, Canada and parts of Europe. The campaign, tracked through September 2025 samples, shifts from macro-laced Excel to embedded executables and employs a DGA plus RSA-signed C2 validation. SafeBreach identified C2 folders including a 'key' directory and a Telegram integration used selectively via a tga.adr file. Analysts warn Infy remains active and dangerous to high-value targets.

🛡️ Researchers have observed renewed activity from the Prince of Persia threat actor, long linked to Iran, after an apparent 2022 hiatus. SafeBreach found updated Foudre and Tonnerre variants, a new domain generation algorithm and altered delivery using Excel files with embedded SFX payloads alongside legacy malicious macros. Select victims can now be controlled via the Telegram API, and identified targets are predominantly in Iran with some victims across Europe, Iraq, Turkey, India and Canada.

🔒 The Iranian-linked group MuddyWater has been observed deploying a new UDP-based backdoor called UDPGangster, using UDP channels for command-and-control, data exfiltration, and remote command execution. Fortinet FortiGuard Labs says the campaign targeted users in Turkey, Israel, and Azerbaijan via spear-phishing messages that deliver macro-enabled Word documents (e.g., "seminer.doc" inside "seminer.zip") and display a Hebrew-language decoy image. The embedded VBA macro decodes Base64 content into C:\Users\Public\ui.txt and launches it via CreateProcessA; the payload establishes registry persistence and runs multiple anti-analysis checks before communicating over UDP to 157.20.182[.]75:1269 to exfiltrate data, run commands with "cmd.exe", transfer files, and deploy additional payloads.

🔒 ESET reports Iranian-aligned MuddyWater has deployed a previously undocumented backdoor named MuddyViper against Israeli organizations across academia, engineering, local government, manufacturing, technology, transportation, and utilities, as well as one Egyptian technology company. The intrusions began with spear-phishing PDFs and exploitation of VPN and remote-access vulnerabilities to deliver loaders called Fooder, which decrypt and execute the C/C++ backdoor or drop tunneling proxies and browser-data collectors. MuddyViper implements about 20 commands for reconnaissance, file transfer, command execution, and exfiltration of Windows credentials and browser data; several Fooder variants masquerade as the Snake game and use delayed execution to evade detection.

🔎 An Amazon Integrated Security report describes Iran-linked actors conducting digital reconnaissance to enable real-world attacks, a phenomenon the company terms cyber-enabled kinetic targeting. Researchers attribute AIS and CCTV intrusions to Imperial Kitten (aka Tortoiseshell) between December 2021 and January 2024 that preceded a missile attempt on a commercial vessel. Amazon also links MuddyWater activity in mid-2025 to live camera access in Jerusalem and notes the use of anonymizing VPNs to complicate attribution and refine target selection.

🎯 Amazon’s threat intelligence linked Iran-associated APT activity to missile strikes in the Red Sea and Israel, concluding cyber espionage provided direct targeting intelligence. The group known as Imperial Kitten queried AIS ship-tracking data days before a Houthi missile attempt, while MuddyWater gained access to compromised CCTV streams ahead of strikes on Jerusalem. Amazon terms this trend cyber-enabled kinetic targeting and urges maritime, surveillance, and critical infrastructure operators to expand threat models and harden systems that could be repurposed for physical attacks.

🛡️ Mandiant has linked suspected Iranian espionage actors to a sustained campaign by UNC1549 that deployed backdoors such as TWOSTROKE and DEEPROOT against aerospace, aviation, and defense organizations in the Middle East. Operating from late 2023 through 2025, the group abused trusted third parties and VDI sessions to pivot into customer environments and leveraged highly targeted, role‑relevant phishing. Observed operations combined credential theft, lateral movement, custom tunnellers and credential‑stealing utilities to execute long‑term reconnaissance and data exfiltration.

🛡️ The Israel National Digital Agency (INDA) has attributed a new espionage campaign codenamed SpearSpecter to Iranian state‑aligned APT42, active since September 2025 against senior defense and government officials and their family members. Operators employ tailored social engineering—invites to conferences and impersonated WhatsApp contacts—to deliver a WebDAV‑served .LNK via the search‑ms: handler that retrieves a batch script and stages the TAMECAT PowerShell backdoor. TAMECAT uses HTTPS, Discord, and Telegram for command-and-control, supports modular data‑theft capabilities (browser and Outlook exfiltration, screenshots), and relies on Cloudflare Workers, LOLBins, in‑memory execution, and obfuscation to maintain persistent, stealthy access.

🔍 Proofpoint attributes a previously unseen cluster, UNK_SmudgedSerpent, to targeted attacks on U.S. academics and foreign‑policy experts between June and August 2025. The adversary used tailored political lures and credential‑harvesting landing pages, at times distributing an MSI that deployed legitimate RMM software such as PDQ Connect. Tactics resemble Iranian-linked groups and included impersonation of think‑tank figures to increase credibility.

⚠ State-sponsored Iranian group MuddyWater deployed version 4 of the Phoenix backdoor against more than 100 government and diplomatic entities across the Middle East and North Africa. The campaign began on August 19 with phishing sent from a NordVPN-compromised account and used malicious Word macros to drop a FakeUpdate loader that writes C:\ProgramData\sysprocupdate.exe. Researchers observed Phoenix v4 using AES-encrypted embedded payloads, COM-based persistence, WinHTTP C2 communications and an accompanying Chrome infostealer, while server-side C2 was taken offline on August 24, suggesting a shift in operational tooling.

🔒 Group-IB links a broad espionage campaign to Iran-aligned MuddyWater that leveraged a compromised email account accessed via NordVPN to send convincing phishing messages. The actor distributed weaponized Microsoft Word documents that coax recipients to enable macros, which execute VBA droppers that write and decode a FakeUpdate loader. FakeUpdate installs an AES-encrypted payload that launches the Phoenix v4 backdoor. Targets exceeded 100 organisations across the MENA region, predominantly diplomatic and government entities.

🔒 Researchers have uncovered a global phishing campaign that used compromised mailboxes to deliver malicious Microsoft Word attachments, attributed with high confidence to the Iran-linked actor MuddyWater by Group-IB. The operation abused a NordVPN-accessed mailbox to send trusted-looking messages that prompted users to enable macros, which then installed the Phoenix v4 backdoor. Investigators also found RMM tools (PDQ, Action1, ScreenConnect) and a Chromium_Stealer credential stealer, while infrastructure traced to the domain screenai[.]online and an IP tied to NameCheap-hosted services.

🔒Former national security adviser John Bolton has been charged with mishandling classified information after prosecutors say he retained and transmitted sensitive documents via a personal AOL account that was later accessed by suspected Iranian hackers. The intruders allegedly downloaded the materials and sent extortion messages to Bolton. The case highlights questions about password strength, the use of two-step verification, and the risks of sending unencrypted, sensitive information to family members. Bolton has pleaded not guilty.

🔍 Check Point Research reports that Iranian-linked actor Nimbus Manticore has escalated cyber-espionage operations across Western Europe, with heightened targeting of organizations in Denmark, Sweden and Portugal. Attackers impersonate recruiters and use convincing fake career portals to deliver personalized credentials and malicious archives. The campaign leverages evolved backdoors—first seen as Minibike, now observed as MiniJunk and MiniBrowse—and employs multi-stage DLL sideloading into legitimate Windows binaries, including Microsoft Defender components, alongside valid code-signing certificates and compiler-level obfuscation to evade detection. Infrastructure hosted via Azure App Service and shielded by Cloudflare provides redundancy and rapid command-and-control recovery.

🛡️ Check Point Research reports that Iranian-linked threat actor Nimbus Manticore is expanding operations into Europe, focusing on the defense, telecom and aerospace sectors. The group uses fake job portals and targeted spear‑phishing to deliver malicious files disguised as hiring materials while impersonating prominent aerospace firms. Evolving toolsets such as MiniJunk and MiniBrowse enable stealthy data theft and persistent access, consistent with intelligence-collection objectives linked to IRGC priorities.

🔒 PRODAFT links a recruitment-themed espionage campaign to an Iran-affiliated cluster tracked as Subtle Snail and attributed to UNC1549 (aka TA455), reporting infiltration of 34 devices across 11 telecommunications organizations in Canada, France, the UAE, the UK and the US. Operators posed as HR recruiters on LinkedIn and delivered a ZIP-based dropper that uses DLL side-loading to install the modular backdoor MINIBIKE, which harvests credentials, browser data, screenshots, keystrokes and system details. MINIBIKE communicates with C2 infrastructure proxied through Azure services, employs anti-analysis measures and achieves persistence via registry modifications to enable long-term access and data exfiltration.

🎭 In episode 435 of Smashing Security, host Graham Cluley and guest Jenny Radcliffe discuss a sophisticated phishing campaign that used fake casting calls to lure Israeli performers, illustrating how flattering, opportunity-based lures can be as persuasive as fear-based tactics. They also cover Check Point’s findings on Iran-linked activity, the UK ICO’s warning about students hacking schools, and lighter cultural items including Endeavour and a local “Catman” story. The episode blends practical security analysis with humour and sponsored segments.

📧 Israeli cybersecurity company Dream has attributed a coordinated, multi-wave spear-phishing campaign to Iranian-aligned operators connected to Homeland Justice, targeting embassies, consulates, and international organizations globally. Attackers used geopolitical lures and 104 unique compromised sender addresses — including a hacked mailbox at the Oman Ministry of Foreign Affairs in Paris — to distribute Microsoft Word documents that prompt users to Enable Content and run embedded VBA macros. The macros drop executables that establish persistence, contact command-and-control servers, and harvest system information; ClearSky has also documented related activity and linked it to prior Iranian techniques.
