The Knownsec leak exposes a state-aligned Chinese cyber contractor deeply integrated with national security and intelligence operations. Internal documents reveal Knownsec's role in developing offensive cyber capabilities, large-scale reconnaissance systems, and data fusion platforms for public security bureaus and military clients. Key products include ZoomEye for global IP scanning, GhostX for exploitation, and Passive Radar for covert network mapping. The leak provides unprecedented insight into Knownsec's organizational structure, personnel, and strategic targeting of foreign critical infrastructure, particularly in Taiwan and other Asian countries. It demonstrates how commercial entities like Knownsec function as core components of China's cyber-espionage ecosystem, blending state objectives with industrial-scale development of intrusion and surveillance technologies.

CNCERT and Microstep Online jointly detected a cyberattack campaign launched by the "Black Cat" criminal gang. This gang uses search engine SEO (Search Engine Optimization) techniques to push meticulously crafted phishing websites to the top of search engine keyword results. After visiting these high-ranking phishing pages, users are lured by carefully designed download pages, attempting to download software installation packages bundled with malicious programs. Once installed, the program implants a backdoor Trojan without the user's knowledge, leading to the theft of sensitive data from their host computer by attackers.
MuddyWater APT group has launched a spearphishing campaign targeting various sectors in the Middle East, including diplomatic, maritime, financial, and telecom entities. The campaign employs icon spoofing and malicious Word documents to deliver a Rust-based implant dubbed 'RustyWater'. This new tool represents a significant upgrade from their traditional PowerShell and VBS loaders, offering capabilities such as asynchronous C2, anti-analysis features, registry persistence, and modular post-compromise expansion. The attack chain involves a malicious email with an attached document that triggers a multi-stage process, ultimately leading to the deployment of the RustyWater implant. This evolution in MuddyWater's toolkit demonstrates their adaptation to more sophisticated, structured, and stealthy attack methods.
This analysis examines a sophisticated malware delivery chain that begins with a phishing email impersonating DocuSign. The attack employs multiple evasion techniques, including an access-code gate, time-based checks, and packing. The initial payload is a single-file .NET bundle with a valid code signing certificate. Static analysis revealed a second-stage native binary with additional obfuscation. The final payload is identified as Vidar malware. The investigation showcases the effectiveness of combining static and dynamic analysis tools to overcome advanced evasion tactics and reconstruct the full attack chain, from the initial phishing email to the final payload.

Three malicious npm packages were discovered in November 2025, designed to deliver and install a new RAT malware family named NodeCordRAT. The packages, bitcoin-main-lib, bitcoin-lib-js, and bip40, mimicked legitimate Bitcoin-related libraries to deceive developers. NodeCordRAT uses Discord for command-and-control communication, targets Chrome credentials, sensitive secrets, and MetaMask data. It performs host fingerprinting, executes shell commands, captures screenshots, and exfiltrates data. The malware exploits software supply chain vulnerabilities, highlighting the importance of vigilance in package management. Although removed from npm, the incident serves as a reminder of ongoing threats in the software development ecosystem.

Key takeaways Introduction GoBruteforcer is a botnet that turns compromised Linux servers into scanning and password brute-force nodes. It targets internet-exposed services such as phpMyAdmin web panels, MySQL and PostgreSQL databases, and FTP servers. Infected hosts are incorporated into the botnet and accept remote operator commands.  Newly discovered weak credentials are used to steal data, […] The post Inside GoBruteforcer: AI-Generated Server Defaults, Weak Passwords, and Crypto-Focused Campaigns appeared first on Check Point Research .
Threat actors are leveraging complex routing scenarios and misconfigured spoof protections to send phishing emails that appear to be internal communications. These attacks, which have increased since May 2025, use various lures like voicemails, shared documents, and password resets to conduct credential phishing and financial scams. The campaigns, often using PhaaS platforms like Tycoon2FA, are opportunistic and target multiple industries. While Microsoft detects most attempts, organizations can further mitigate risks by properly configuring spoof protections and third-party connectors. The attacks do not affect customers whose Microsoft Exchange MX records point to Office 365, as they are protected by built-in spoofing detections.
