• Microsoft "mitigates" Windows LNK Flaw Exploited As Zero-Day
  "Microsoft has silently "mitigated" a high-severity Windows LNK vulnerability exploited by multiple state-backed and cybercrime hacking groups in zero-day attacks. Tracked as CVE-2025-9491, this security flaw allows attackers to hide malicious commands within Windows LNK files, which can be used to deploy malware and gain persistence on compromised devices. However, the attacks require user interaction to succeed, as they involve tricking potential victims into opening malicious Windows Shell Link (.lnk) files. Threat actors distribute these files in ZIP or other archives because email platforms commonly block .lnk attachments due to their risky nature."

Malware

• Shai-Hulud V2 Poses Risk To NPM Supply Chain
  "On November 24, 2025, security researchers detected a second wave of the Shai-Hulud malware campaign targeting the npm ecosystem. Dubbed The Second Coming by its operators, Shai-Hulud V2 builds upon its predecessor, Shai-Hulud V1, and has established itself as an aggressive software supply chain attack. Within hours of its initial detection, the campaign had compromised over 700 npm packages, created more than 27,000 malicious GitHub repositories, and exposed approximately 14,000 secrets across 487 organizations."

• Technical Analysis Of Matanbuchus 3.0
  "Matanbuchus is a malicious downloader, written in C++, which has been offered as a Malware-as-a-Service (MaaS) since 2020. Over this time, Matanbuchus has undergone several development stages. In July 2025, version 3.0 of Matanbuchus was identified in-the-wild. Matanbuchus offers threat actors the option to deploy additional payloads and perform hands-on keyboard activity via shell commands. Despite its simplicity, Matanbuchus has been more recently associated with ransomware operations."

• V3G4 Botnet Evolves: From DDoS To Covert Cryptomining
  "Cyble Research & Intelligence Labs (CRIL) has identified an active Linux-targeting campaign that deploys a Mirai-derived botnet, paired with a stealthy, fileless-configured cryptominer. The threat actor employs a multi-stage infection chain starting with a downloader that delivers architecture-specific V3G4 binaries across x86_64, ARM, and MIPS systems. Once active, the bot masquerades as systemd-logind, performs environment reconnaissance, conducts large-scale raw-socket SSH scanning, maintains persistent C2 communication, and ultimately launches a concealed XMRig-based Monero miner dynamically configured at runtime."

• DIANNA Explains 4: Nimbus Manticore—Monstrous Malware
  "Hey humans, DIANNA here. I’m back again with another malware teardown. This time, we're looking at a piece of malware called Nimbus Manticore, and I'll say this upfront—whoever named this malware has a flair for the dramatic. The capabilities, though? All business. Nimbus Manticore represents a serious challenge for organizations because it's not just designed to compromise a single endpoint. It's built to move laterally through your network, escalate privileges, and establish a persistent presence across multiple systems."

• How a Fake ChatGPT Installer Tried To Steal My Password
  "Over the Thanksgiving holiday, I embarked on a small project to evaluate AI browsers, including the buzzy ChatGPT Atlas. Like most people, I clicked the first result I saw: a sponsored link. The page looked nearly identical to the real Atlas site: same layout, design, copy. The only subtle giveaway was the domain: a Google Sites URL. That’s increasingly common in modern phishing kits—tools like v0.dev make it trivial to clone a legitimate site in minutes, and hosting on Google Sites adds a false sense of credibility for anyone who thinks Google = trustworthy. Given our work here at Fable, I was pretty excited to have stumbled on this, and decided to give it a whirl and see just how much damage I could cause."

• French NGO Reporters Without Borders Targeted By Calisto In Recent Campaign
  "In May and June 2025, TDR team analysts were contacted by two organisations — including the French NGO Reporters Without Borders (RSF) — over suspicions of a new spear phishing attempts by the intrusion set Calisto (also known as ColdRiver or Star Blizzard). Calisto is a Russia-nexus intrusion set active since at least April 2017, attributed by the USA, the UK, New Zealand and Australia to the Russian intelligence service FSB, more specifically to the Center 18 for Information Security (TsIB), military unit 64829, also known to operate the intrusion set Gamaredon. Sekoia.io concurs with such attribution as past Calisto operations investigated by TDR analyst showed objectives and victimology that align closely with Russian strategic interests."

• The $9M yETH Exploit: How 16 Wei Became Infinite Tokens
  "On November 30, 2025, Check Point Research detected a critical exploit targeting Yearn Finance’s yETH pool on Ethereum. Within hours, approximately $9 million was stolen from the protocol. The attacker achieved this by minting an astronomical number of tokens—235 septillion yETH (a 41-digit number)—while depositing only 16 wei, worth approximately $0.000000000000000045. This represents one of the most capital-efficient exploits in DeFi history."

• DNS Uncovers Infrastructure Used In SSO Attacks
  "We recently received a tip from a customer that their institution was under recurring attacks that targeted their student single sign-on (SSO) portal. The threat actor leveraged Evilginx (likely version 3.0), an open source, advanced phishing adversary-in-the-middle (AITM, aka MITM) framework designed to steal login credentials and session cookies. Evilginx is widely used by cybercriminals to undermine multi-factor authentication (MFA) security, and this actor has used it to target at least 18 universities and educational institutions across the United States since April 2025. The campaigns were delivered through email and the phishing domains used subdomains that mimicked the legitimate SSO sites. Figure 1 shows a timeline of attack volumes, based on DNS, against the schools."

• How Attackers Use Real IT Tools To Take Over Your Computer
  "A new wave of attacks is exploiting legitimate Remote Monitoring and Management (RMM) tools like LogMeIn Resolve (formerly GoToResolve) and PDQ Connect to remotely control victims’ systems. Instead of dropping traditional malware, attackers trick people into installing these trusted IT support programs under false pretenses–disguising them as everyday utilities. Once installed, the tool gives attackers full remote access to the victim’s machine, evading many conventional security detections because the software itself is legitimate."

• Shai Hulud 2.0, Now With a Wiper Flavor
  "In September, a new breed of malware distributed via compromised Node Package Manager (npm) packages made headlines. It was dubbed “Shai-Hulud”, and we published an in-depth analysis of it in another post. Recently, a new version was discovered. Shai Hulud 2.0 is a type of two-stage worm-like malware that spreads by compromising npm tokens to republish trusted packages with a malicious payload. More than 800 npm packages have been infected by this version of the worm. According to our telemetry, the victims of this campaign include individuals and organizations worldwide, with most infections observed in Russia, India, Vietnam, Brazil, China, Türkiye, and France."

• Malicious Rust Crate Evm-Units Serves Cross-Platform Payloads For Silent Execution
  "The Socket Threat Research Team recently discovered a malicious Rust package named evm-units, written by ablerust, with over 7,000 all-time downloads. Based on the victim’s OS and whether Qihoo360 antivirus is running, the package downloads a payload, writes it to the system temp directory, and silently executes it. The package appears to return the Ethereum version number, so the victim is none the wiser. The package names and code behavior (EVM utilities, genuine Uniswap helper library), combined with the Qihoo360 targeting and multi-OS loader pattern, make it likely that the payload steals cryptocurrency. The targeting of Qihoo360 also suggests that the threat actor is focusing on Asian markets, as Qihoo360 is a Chinese-made antivirus with dominant marketshare throughout Asia."

• Chinese Researchers Simulate Large-Scale Electronic Warfare Against Elon Musk’s Starlink
  "When Russian forces rolled into Ukraine in early 2022, one of the first moves by Kyiv was sending a post to Elon Musk on X: Ukraine needs satellite internet. Within days, thousands of Starlink terminals arrived, restoring command and control across the battlefield despite Russia’s best efforts to black out communications. Moscow initially tried to jam the signals – and reportedly had some success. But when SpaceX quietly updated its software and reconfigured the constellation, many Russian jammers went silent. The battlefield advantage shifted."

  "Two years ago, the introduction of Encrypted Client Hello (ECH) divided enterprise cybersecurity professionals and privacy advocates. An extension to the Transport Layer Security (TLS) 1.3 Internet encryption standard, ECH protects communications between an endpoint device and a Web server. While ECH increased user privacy, it reduced visibility, which is not so great for security. You are already familiar with TLS: The padlock symbol and https designation in the address bar of your browser indicate the website uses this Internet standard. However, this only means that the content between the client machine and the server is encrypted after the connection has been established."

  "There's never a good time to get hit by ransomware, but fallout can be even more devastating when attacks hit during off-hours, weekends or holidays. That's the time when threat actors strike, knowing enterprises are understaffed. Ransomware gangs are a steady, rising threat that reports show operate as legitimate businesses, complete with customer service and help desk personnel. That reflects in well-thought out attack steps, including timing which commonly correlates with organizations' weekend and holiday downtime, an important tool against staffer burnout."

• PyTorch Users At Risk: Unveiling 3 Zero-Day PickleScan Vulnerabilities
  "JFrog Security Research found 3 zero-day critical vulnerabilities in PickleScan, which would allow attackers to bypass the most popular Pickle model scanning tool. PickleScan is a widely used, industry-standard tool for scanning ML models and ensuring they contain no malicious content. Each discovered vulnerability enables attackers to evade PickleScan’s malware detection and potentially execute a large-scale supply chain attack by distributing malicious ML models that conceal undetectable malicious code. In this blog post, we will explain how PickleScan works and why, despite using model scanning tools, Pickle is still unsafe given these recently discovered zero-day vulnerabilities."

• MuddyWater: Snakes By The Riverbank
  "ESET researchers have identified new MuddyWater activity primarily targeting organizations in Israel, with one confirmed target in Egypt. MuddyWater, also referred to as Mango Sandstorm or TA450, is an Iran-aligned cyberespionage group known for its persistent targeting of government and critical infrastructure sectors, often leveraging custom malware and publicly available tools. In this campaign, the attackers deployed a set of previously undocumented, custom tools with the objective of improving defense evasion and persistence. Among these tools is a custom Fooder loader designed to execute MuddyViper, a C/C++ backdoor. Several versions of Fooder masquerade as the classic Snake game, and its internal logic includes a custom delay function inspired by the game’s mechanics, combined with frequent use of Sleep API calls."

• New eBPF Filters For Symbiote And BPFdoor Malware
  "eBPF—extended Berkeley Packet Filter—is a very interesting kernel technology that lets users load tiny, sandboxed programs into the Linux kernel to inspect or modify network packets, system calls, and more. The technology was introduced in 2015 to renovate the “old” BPF technology of 1992, which was no longer adapted to modern computer architectures (e.g., 64-bit). As usual, the technology was quickly noticed by malware authors, resulting in the Bvp47 malware in 2015, as well as a collection of rootkits, such as Ebpfkit and TripleCross. However, due to the required skills needed to use or exploit eBPF, the malware remains rare (in number). Today, the malware scene mostly consists of two families: Symbiote and BPFDoor, both from 2021."

• The Great Disconnect: Unmasking The ‘Two Separate Conversations’ In Security
  "It is often the case that I witness a conversation that is actually two separate conversations. What do I mean by that? If you are an astute listener and observer, you have probably noticed how often two people are having two completely different conversations. It is seldom the case that either person realizes it, and thus, more often than not, people have difficulty communicating effectively with one another. Quite simply put, they are not having the same conversation."

• The Browser Defense Playbook: Stopping The Attacks That Start On Your Screen
  "The predominance of cloud-based apps and the trend towards remote work have made the browser the place where most work happens. In fact, about 85% of daily work takes place there. In many ways, it’s a win for all involved. Users can work from a wider range of locations and devices, accessing full “desktops” inside a browser tab. Organizations can manage apps and browser access easier than through localized desktop software. This all allows for greater central management, lower costs and better flexibility."
