Rilevata una campagna su larga scala di compromissione della supply chain nell'ecosistema npm, denominata "Mini Shai-Hulud". L'attacco sfrutta un malware di tipo worm per infiltrarsi negli ambienti di sviluppo e nelle pipeline di Continuous Integration/Continuous Deployment (CI/CD). L'obiettivo primario è l'esfiltrazione di credenziali sensibili e la successiva propagazione automatizzata attraverso la pubblicazione di versioni malevole di pacchetti legittimi.
The EtherRAT malware family was first reported by Sysdig back in December 2025. At that time, the initial access vector was exploitation of CVE-2025-55182 (React2Shell) targeting Linux servers. In March 2026, a Windows variant campaign was reported by Atos, with their investigation showing evidence of activity going back to the previous December. In April, we […] The post Flash Alert: EtherRat and TukTuk C2 End in The Gentleman Ransomware appeared first on The DFIR Report.
TrendAI™ Research has identified two emerging threat campaigns—SHADOW-AETHER-040 and SHADOW-AETHER-064—that use agentic AI to drive intrusion operations against government and financial organizations in Latin America, marking these among the first cases we have observed of AI agents executing attacks from initial access to data exfiltration.
Executive Summary SentinelLABS has identified PCPJack, a credential theft framework that worms across exposed cloud infrastructure and removes artifacts associated with TeamPCP, a threat actor persona who claimed several high-profile supply chain intrusions throughout early 2026. The toolset harvests credentials from cloud, container, developer, productivity, and financial services, then exfiltrates the data through attacker-controlled infrastructure while attempting to spread to additional…
Elastic Security Labs identified a new Brazilian banking trojan that we are tracking as TCLBANKER, a malware family we assess is a major update of the MAVERICK/SORVEPOTEL family. The campaign, tracked as REF3076, features a loader with robust anti-analysis capabilities that deploys two embedded .NET Reactor-protected modules: a full-featured banking trojan and a worm module for self-propagation. The banking trojan monitors the victim's browser address bar via UI Automation, targeting 59…
ESET researchers have investigated an ongoing attack by the ScarCruft APT group that targets the Yanbian region via backdoor-laced Windows and Android games
Key Takeaways We identified an exposed server that provided unusual visibility into a large-scale, multi-victim exploitation and collection operation. Artifacts on the host showed that Claude Code and OpenClaw were embedded in the operator’s day-to-day workflow, supporting troubleshooting, orchestration, and refinement of the collection pipeline. This AI-assisted workflow resulted in the modular platform Bissa scanner […] The post Bissa Scanner Exposed: AI-Assisted Mass Exploitation and…
A follow-up publication will provide a deeper technical analysis of PHANTOMPULSE itself, covering its injection engines, persistence internals, and C2 protocol in greater detail. Preamble Elastic Security Labs has identified a novel social engineering campaign that abuses the popular note-taking application, Obsidian, as an initial access vector. The campaign, which we track as REF6598, targets individuals in the financial and cryptocurrency sectors through elaborate social engineering on…
Introduction Elastic Security Labs has been tracking a financially motivated operation, designated REF1695, that has been active since at least late 2023. The operator deploys a combination of RATs, cryptominers, and custom XMRig loaders through fake installer packages. Across all observed campaigns, the infection chains share a consistent packing technique, overlapping C2 infrastructure, and common social engineering patterns, linking them to a single operator. Beyond cryptomining, the threat…
This blog discusses the steganography, cloud abuse, and email-based backdoors used against the Ukrainian defense supply chain in the latest Pawn Storm campaign that TrendAI™ Research observed and analyzed.
Introduction Elastic Security Labs is observing malicious campaigns delivering a multi-stage infection involving a previously undocumented loader. The infection begins when users are diverted to a Cloudflare Turnstile CAPTCHA page under the guise of a digital invitation. After the link is clicked, a VBScript file is downloaded to the machine. Upon execution, the script retrieves C# source code, which is then compiled and executed in memory using PowerShell. The final payload observed in these…
