CyberStrikeAI is an open-source AI-driven attack framework used in real-world campaigns targeting educational institutions in Africa and Latin America. It combines large language model (LLM) orchestration with a traditional command-and-control (C2) server, where an AI model generates commands executed by implants on compromised hosts. Initial access was gained via compromised SQL Server infrastructure. The framework automates post-exploitation activities such as reconnaissance, privilege escalation, credential dumping, lateral movement, and data exfiltration using standard techniques like Kerberoasting, AS-REP Roasting, LSASS dumps, DCSync, and Golden Ticket attacks. The AI orchestration reduces the skill barrier for attackers by automating tasks that normally require manual intervention. Despite the AI component, the malicious actions on victim systems use well-known techniques detectable by conventional security controls.
An exposed open directory at a staging server revealed an active intrusion by operators linked to The Gentlemen ransomware group. The operation involved establishing persistent access through privileged account creation, credential theft via LSASS dumping, and lateral movement across a Windows domain. Attackers deployed multiple implants including EtherRAT, which retrieves command-and-control domains from an Ethereum smart contract, alongside Sliver and custom Go reverse shells. Lateral movement was achieved through remote scheduled tasks distributing MSI payloads, while security products were disabled and reverse tunnels established for persistent access. The infrastructure and tactics align with previously documented The Gentlemen campaigns, including a ClickFix operation deploying EtherRAT.
GenieLocker is a new ransomware family active since March 2026, targeting organizations in the Russian Federation, primarily in manufacturing. Attributed to the financially motivated Toy Ghouls group (also known as Bearlyfy, Labubu, and Laboo.boo), this custom-designed ransomware marks a shift from their previous reliance on third-party encryption tools like RedAlert, LockBit, and Babuk. GenieLocker exists in two variants: PE builds for Windows and ELF builds for Linux and ESXi. The Windows version features sophisticated capabilities including process termination, service shutdown, anti-debugging techniques, and advanced encryption using the libsodium library with XChaCha20-Poly1305 algorithm. Initial access typically occurs through compromised VPN credentials from trusted partners, followed by deployment of tools like Mimikatz, SoftPerfect Network Scanner, and SSH utilities for lateral movement before deploying ransomware using PsExec and PAExec.
Since late 2025, government and diplomatic entities in Southeast Asia have been targeted by sophisticated attacks involving GoSerpent, a Go-based RAT with proxy capabilities. The malware receives encrypted arguments and deploys additional tools for data collection and credential dumping. GoSerpent has been active since 2021, with newer variants using AES-CBC encryption and ChaCha20 for communications. The campaign involves multiple stages: initial deployment of GoSerpent and ThumbcacheService to collect sensitive files, credential dumping via Mimikatz and QuarksDumpLocalHash, followed by deployment of Stowaway RAT in May 2026 and TmcLoader/TmcPayload for stealthy data exfiltration through network shares. The integrated toolset demonstrates sophisticated operational planning, with attackers leveraging Alibaba Cloud and UCLOUD HK infrastructure while exhibiting possible connections to the TetrisPhantom threat actor.
CVE-2025-5777, known as CitrixBleed 2, is a memory-overread vulnerability in Citrix NetScaler ADC and Gateway appliances. It allows attackers to send malformed pre-authentication login requests that leak memory containing valid session tokens, enabling session hijacking and bypass of multi-factor authentication. Exploitation leads to privilege escalation via a registry-symlink technique targeting the AppMgmt service, creation of rogue administrator accounts, and persistence through legitimate remote access tools. The vulnerability has been actively exploited in multiple unrelated organizations, culminating in deployment of DragonForce ransomware in the most severe cases. The attack chain is highly standardized, indicating a single initial access broker. The vulnerability is listed in the CISA KEV catalog and public exploit code is available. Patch status is not confirmed in the provided data.
GodDamn ransomware represents the third iteration of ransomware developed by Hyadina, following Monster (2022) and Beast (2024). A recent attack in June 2026 demonstrates sophisticated tactics including AnyDesk for remote access, NirSoft-based credential harvesting tools, and the PoisonX kernel driver for defense evasion. PoisonX is a malicious driver signed by Microsoft that terminates security processes at the kernel level. Attackers used PsExec for lateral movement, deployed comprehensive credential theft toolkits comprising 14 different tools, and disabled endpoint defenses before encrypting files. The encrypted files were renamed with victim organization names as extensions. The four-day dwell period allowed attackers to stage payloads and conduct reconnaissance before triggering encryption across at least 10 hosts within the targeted organization.
Throughout 2025, Chinese-speaking threat actors tracked as CL-STA-1062 conducted extensive operations against government entities and critical infrastructure in Southeast Asia, specifically targeting state-owned enterprises in energy and government sectors. Active since March 2022, this cluster was previously identified as UAT-7237 in campaigns against Taiwan's web hosting infrastructure. The attackers employ a hybrid toolkit combining open-source tools like SoftEther VPN, Mimikatz, and VNT with a newly discovered custom backdoor called TinyRCT. This .NET-based backdoor provides capabilities including arbitrary command execution, file enumeration and exfiltration, screen capture, and self-destruct mechanisms. The infection chain typically begins with web application exploitation deploying ASPX web shells, followed by credential dumping, lateral movement, and data exfiltration. Between October and December 2025, at least ten organizations across Southeast Asia were compromised, demonstrating sustained regio...
Trigona ransomware affiliates have developed and deployed a custom exfiltration tool named uploader_client.exe, observed in attacks during March 2026. This tool uses parallel data streams, connection rotation, and file filtering to evade detection and streamline data theft. Attackers disable endpoint protections at the kernel level using multiple utilities before exfiltration. Remote access and credential theft are facilitated by AnyDesk and tools like Mimikatz. This represents a more technically sophisticated approach than typical ransomware affiliate operations.
The Gentlemen ransomware-as-a-service program has rapidly expanded since mid-2025, claiming over 320 victims with 240 attacks occurring in early 2026. The service provides multi-platform lockers for Windows, Linux, NAS, BSD, and ESXi, enabling comprehensive coverage of corporate environments. During an incident response engagement, an affiliate deployed SystemBC proxy malware for covert tunneling and payload delivery. Analysis of the SystemBC command-and-control server revealed a botnet of over 1,570 victims, primarily corporate and organizational targets. The intrusion progressed from domain controller compromise through credential validation, remote execution via administrative shares, and deployment of Cobalt Strike payloads. Attackers disabled defenses, established persistence through scheduled tasks and services, and ultimately deployed ransomware via Group Policy. The operation demonstrates sophisticated lateral movement capabilities, defense evasion techniques, and integration of mature post-exploit...
North Korean state-backed attackers are utilizing Medusa ransomware in their ongoing extortion attacks against the U.S.healthcare sector. The Symantec and Carbon Black Threat Hunter Team discovered evidence of North Korean actors employing Medusa in an attack on a Middle Eastern target and an unsuccessful attempt on a U.S.healthcare organization. Medusa, launched in 2023, operates as a ransomware-as-a-service. The Lazarus sub-group Stonefly has been a key player in North Korean ransomware attacks, using proceeds to fund espionage activities. Despite indictments and rewards, the attacks continue unabated. The current campaign employs various tools, including Comebacker, Blindingcan, ChromeStealer, and RP_Proxy. While the attacks bear similarities to previous Stonefly operations, the exact sub-group responsible remains unclear.
A new ransomware called Osiris was used in an attack on a major food service franchisee operator in Southeast Asia in November 2025. The ransomware shares similarities with previous Inc ransomware attacks, including the use of Wasabi buckets for data exfiltration and a specific version of Mimikatz. Osiris has typical ransomware functions, uses a hybrid encryption scheme, and drops a ransom note. The attack chain involved data exfiltration using Rclone, deployment of dual-use tools, and the use of a malicious driver called Abyssworker or Poortry. The attackers employed bring-your-own-vulnerable-driver (BYOVD) techniques to disable security software. While the impact of Osiris on the ransomware landscape remains uncertain, it appears to be wielded by experienced attackers with potential links to Inc ransomware or its affiliates.
