NeedyMantis malware enables persistent access

đź”’ Microsoft analyzed a malware family called NeedyMantis, used to maintain long-term access in targeted intrusions affecting telecoms, universities, medical nonprofits, intergovernmental organizations, and contractors. The activity dates back to at least October 2025 and was discovered while investigating the DAEMON Tools supply chain compromise. NeedyMantis operates via DLL sideloading: a legitimate program, a malicious DLL, and an encrypted archive load in sequence to unpack and run a main component that connects to a C2 over HTTPS and WebSocket. Microsoft published file hashes, domains, file paths, hunting queries, and Defender detection names to help defenders identify and remediate infections.

RatHat Android banking trojan console exposed

🛡️ Cleafy links the RatHat Android banking trojan to a web-based control console used in nearly 100 deployments since April 2026. The console stores stolen data from infected phones and can build, sign, and publish malicious apps automatically. Its latest variant uses Google's Gemini AI to estimate victims' bank balances and prioritize high-value targets. Operators gain one-click shell access via ADB and a Go-based agent that streams the screen without permission prompts on older Android versions.

JadePuffer agentic AI attacks target Azure tenants

đź”’ Researchers report that the JadePuffer ransomware operator is conducting agent-driven attacks against Azure tenants to perform reconnaissance, steal credentials, and destroy cloud resources. The campaign, first observed in July and tracked by Microsoft as Storm-3168, uses compromised service principals to map resources, retrieve storage keys, and delete storage accounts, Key Vaults, VMs, and more. Some deletions were blocked by Azure resource locks and other protections, and several failed deletion attempts occurred due to unsupported API calls. Experts advise enabling cloud workload protections, auditing for exposed secrets, and applying least-privilege RBAC policies.

Dutch police arrest former hacker linked to ShinyHunters

📰 Dutch authorities arrested a 23-year-old convicted cybercriminal, identified by sources as Pepijn van der Stap, on suspicion of aiding the ShinyHunters hacking collective in data thefts and extortion. Van der Stap — previously convicted in 2023 and released in December 2025 — had presented himself as reformed while working in offensive security. Following his detention, ShinyHunters escalated attacks, claiming breaches of the FBI jobs site and extorting other groups, exploiting a PeopleSoft flaw (CVE-2026-35273). Investigations continue into ties between ShinyHunters, a rival teenage operator known as Rey, and recent large-scale data thefts.
