DarkTortilla is a sophisticated and adaptable.NET-based crypter, active since at least August 2015, known for delivering a range of malicious software, including prevalent information stealers and remote access trojans like AgentTesla, AsyncRat, NanoCore, and RedLine.

TL;DR: We found another delayed RCE in MECCHA CHAMELEON. When playing on an attacker’s map, they can abuse an exposed function to arbitrarily write files to the victim’s system. This can lead to remote code execution on the victim’s system after a restart. We reported the issue to the game’s maintainers, and they fixed the vulnerability in the 4.0.0 update. This update is automatically installed before launching the game.

Originally published on Cybersecurity Insiders. Phishing remains one of the most reliable entry points for attackers, serving as the initial intrusion vector in 58% of incidents analyzed in LevelBlue’s Q1 2026 TTP Briefing. But today’s campaigns are becoming increasingly targeted and technically sophisticated, evolving from simply convincing a user to click to establishing long-term access to enterprise environments.

Over recent months, our Microsoft Managed Detection and Response (MDR) service, powered by the Threat Fusion Cell, has observed a sharp increase in sophisticated attack campaigns attributed to offshoots of threat brand Vocal Brigantine, who ceased operations in Spring 2026.

On August 31, 2026, CrowdStrike's Counter Adversary Operations team, in collaboration with international law enforcement and industry partners, executed a coordinated disruption of the Sality peer-to-peer (P2P) botnet, a criminal infrastructure that has operated with seeming impunity for more than two decades. The botnet enabled the operator to distribute malicious payloads to over 15,000 infected machines worldwide.

Originating in early 2023, Pikabot emerged as a significant malware loader. Over the past year, ThreatLabz has diligently monitored its development and operational methods. Notably, there was a surge in Pikabot’s usage in the latter part of 2023, attributed to a BlackBasta ransomware affiliate adopting Pikabot post the FBI-led Qakbot takedown. However, Pikabot’s activity ceased shortly after Christmas 2023, with version 1.1.19 marking its endpoint.

On August 28, 2026, ten malicious versions of @7nohe/openapi-react-query-codegen were published to npm between 20:00 and 20:21 UTC. The package generates React Query hooks from an OpenAPI schema and draws roughly 150,000 weekly downloads. The latest tag pointed at the malicious 3.0.4 for the duration of the window. Eight of the ten releases carry a multi-stage loader that reaches for cloud, registry, and developer credentials. The attacker needed no stolen npm token and no hijacked maintainer account.
