The MAL Simulator: Cyber Operations Simulation based on Attack & Defense Graphs

MAL Simulator grounds attack-defense graph simulations in a CRATE-emulated network, training RL attacker and defender agents where attackers outperform search methods.

The MAL Simulator is a cyber operations simulator built on the Meta Attack Language (MAL), enabling decision-driven attack and defense simulations adaptable to new domains without modifying source code. Case studies trained defensive and offensive agents, grounded in data collected from an emulated network implemented in the CRATE cyber range. The trained attacker policy reached designated targets more efficiently than compared search methods, and the trained defender induced lower costs than a naive heuristic under noisy alerts, though defender performance dropped significantly against an RL attacker.

CISA Releases Guidance on Deploying Cyber Decoys

CISA issued guidance on deploying honeypots, honeytokens, and decoy systems to detect adversaries and gather threat intelligence in critical infrastructure.

CISA released guidance on deploying cyber decoys, including lures, tripwires, decoy artifacts, honeytokens, and honeypots, within critical infrastructure organizations to complement Zero Trust models. The guidance outlines a three-phase operational process of preparation, execution, and understanding, advising decoys be placed where users rarely interact and configured to produce high-fidelity alerts. It aims to help defenders detect adversaries who use legitimate credentials, native tools, and living-off-the-land techniques, while enabling cost-effective threat intelligence collection.

Using Cyber Decoys to Strengthen Detection and Response

CISA released guidance on cyber decoys—tripwires, breadcrumbs, honeytokens—to help defenders detect adversaries using valid credentials and living-off-the-land techniques.

CISA published guidance to help defensive teams of varying maturity plan and implement cyber decoys—assets that mimic legitimate systems, accounts, or data, such as tripwires, breadcrumbs, and honeytokens—to detect adversaries using legitimate credentials and living-off-the-land techniques. The guidance frames decoys as complementing Zero Trust by producing high-fidelity alerts, reducing alert fatigue, and exposing post-compromise activity like discovery, lateral movement, and data access. It maps decoy operations to the MITRE Engage and MITRE ATT&CK frameworks with low-complexity implementation steps.

Hackers Use Cross-Platform Noodle RAT to Secretly Control Windows and Linux Systems

Check Point identifies Noodle RAT as a distinct cross-platform Windows/Linux backdoor used by Chinese-speaking actors against Asia-Pacific organizations since 2016.

Check Point assesses Noodle RAT, also known as ANGRYREBEL, as a distinct backdoor family rather than a variant of Gh0st RAT or Rekoobe, with separate Windows (Win.NOODLERAT) and Linux (Linux.NOODLERAT) variants sharing a common command-and-control design. The Windows implant runs filelessly via shellcode with loaders like MULTIDROP and MICROLOAD, while the Linux variant provides reverse shells, file management, and SOCKS tunneling after exploitation or web-shell placement on exposed servers. Groups including Iron Tiger, Calypso APT, Rocke, and Cloud Snooper have deployed it against organizations in Thailand, India, Japan, Malaysia, and Taiwan. Check Point released sample hashes and C2 IP indicators alongside the analysis.

FamousSparrow Exploits Public-Facing Exchange Servers to Deploy SparroWocky Backdoor

ESET attributes a new SparroWocky backdoor to espionage group FamousSparrow, deployed via exploited internet-facing Exchange servers across Latin American governments.

ESET's Welivesecurity team reports FamousSparrow gained initial access by exploiting publicly reachable Microsoft Exchange servers, with roughly 90 percent of targets since mid-2025 in Latin America, including governments in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico, and Venezuela. The group's new modular C-language backdoor SparroWocky replaces SparrowDoor and uses a three-part loader: a legitimate executable, a malicious DLL side-loaded in memory, and an encrypted payload. It persists via Windows services or Registry Run keys, supports screenshots, file operations, TCP proxying, Beacon Object Files, TLS/RC4-encrypted C2, and anti-forensics such as call-stack spoofing. IOCs including loader SHA-1 hashes and C2 IP addresses were published.

Google’s New Search Redirects Make It Harder to Check Where Links Lead Before Clicking

Malwarebytes reports Google's new encoded google.com/goto?url= redirects break hover-preview link checking, weakening a common phishing defense.

Google now routes some search results through opaque google.com/goto?url= redirects using custom encoding, so browser link previews no longer reveal the true destination, only the claimed label above the result. Malwarebytes found the final destination is visible only in the redirect response's Location header, complicating hover-based safety checks as well as scraping, archiving, and audit tools. The change arrives amid malvertising, search-result poisoning, and fake installer campaigns like the recent Node.js infostealer lure. Google says it deploys measures against evolving abuse but did not explain the change.

Chosen Brick, Iran’s Surveillance Malware

UK, US, and Dutch agencies warn Iranian CHOSEN BRICK malware targets dissidents and journalists via Telegram, harvesting contacts, emails, and messages since 2025.

The UK NCSC, FBI, and Dutch AIVD jointly attributed the CHOSEN BRICK Windows malware family to Iranian intelligence services, used since at least 2025 against dissidents, journalists, and activists worldwide, including in the UK, US, and Netherlands. Operators build rapport over WhatsApp or Telegram, impersonating known contacts or platform support, then deliver lures disguised as installers for Pictory, RunwayML, Norton Antivirus, Telegram, Adobe Flash Player, or KeePass, or fake MRI results. The malware persists via registry Run keys, adds Microsoft Defender exclusions, and uses per-victim Telegram bot IDs for C2, with newer versions adding HTTPS or SOCKS5 proxies. Some victims' data appeared on pro-Iranian leak sites, raising harassment and physical-safety risks.
