Threat Research | Weekly Recap [12 Oct 2025]

Cybersecurity Threat Research ‘Weekly’ Recap. The report highlights ongoing package-manager abuse, covert C2 channels, and extortion trends, including malicious npm packages, Discord-based C2, and double-extortion operations. It also covers high-severity vulnerabilities being actively exploited, phishing advancements, information-stealing and MaaS developments, and the rise of malware-less database ransomware, with emphasis on detection challenges and CTI considerations.

Package-ecosystem & supply-chain abuse

Covert C2 & platform abuse

  • Novel Rust backdoor “ChaosBot” and other malware used Discord as a C2 channel, supporting remote commands, file transfer, and proxying. ChaosBot Rust backdoor (Discord C2).

Ransomware & extortion operations

Access, exploits & critical vulnerability exploitation

Phishing & social-engineering campaigns

Infostealers, loaders, MaaS & access brokers

Messaging worms, banking trojans & mobile threats

  • A WhatsApp Web worm campaign in Brazil used ZIP→LNK→PowerShell chains to disable defenses and deliver a Selenium hijacker or Maverick banking trojan. WhatsApp Web worm delivering Maverick.
  • ClayRat Android spyware sideloaded via Telegram/phishing pages stole SMS, calls, notifications, photos and self-propagated to contacts once granted SMS handler privileges. ClayRat Android spyware via sideloading.

Crypto scams & fraud infrastructure

  • Coordinated crypto-scam network hosted fake wallet sites, malicious extension flows and profile “apps” to drain wallets; infrastructure and artifacts mapped to specific IPs/domains. Coordinated crypto-scam nexus & wallet phishing.

Database & infrastructure extortion (malware-less attacks)

  • Attackers increasingly perform “malware-less” database ransomware by abusing exposed/misconfigured DBs (MongoDB, Postgres, MySQL, Redis, Elasticsearch) with legitimate DB commands for theft/destruction and ransom notes. Malware-less database ransomware trends & defenses.

Detection, research, and threat intelligence quality

  • NVD suffered a backlog with ~70% of recent CVEs awaiting analysis, urging use of alternative vulnerability sources (OSV.dev, vendor advisories) for timely patching. Vulnerability data crisis in NVD & mitigations.
  • Kaspersky integrated an ML model into Kaspersky SIEM to detect DLL-hijacking (sideloading) and flagged real-world incidents (ToddyCat/Cobalt Strike, infostealer loaders). ML detection of DLL hijacking in SIEM.
  • LABScon25 replay cautions on AI-agent use in CTI: productivity gains vs reliability/transparency risks; calls for adapted tradecraft and clear AI-assisted reporting. AI agents in CTI: analytical tradecraft risks.
  • Elastic Security Labs’ 2025 Global Threat Report highlights AI-driven shifts, infostealer prevalence, and concentrated cloud attacks (Initial Access, Persistence, Credential Access). Elastic 2025 Global Threat Report.
