In late May 2026, Belarus-aligned threat actors known as FrostyNeighbor deployed a VBScript wiper malware against a Ukrainian manufacturing company in the transportation sector. This represents the first documented destructive cyberattack by a Belarus-aligned group, marking a shift from espionage to destructive operations. The attackers used tools including Chisel, UltraVNC, and Cobalt Strike, delivering the destructive payload via Group Policy. The targeting of a transportation-related company suggests potential wartime operational objectives. Researchers note increasing aggression from Belarus-aligned groups, possibly acting as proxies for Russian intelligence, though direct cooperation is unconfirmed.
Researchers uncovered an AI-driven intrusion ecosystem operated by affiliates of INC and The Gentlemen ransomware groups via seven exposed command-and-control servers. The operators integrated commercial AI models, exploited edge devices at scale, and compromised thousands of targets, primarily in the US industrial manufacturing and healthcare sectors. The infrastructure included multiple custom encryptor builds and evidence of active victim encryption. Operational security failures exposed source code, credentials, AI session logs, and victim data. The campaign demonstrates advanced ransomware-as-a-service operations leveraging AI and custom tooling.
An Iranian state-aligned threat actor known as CL-STA-1178 has been conducting the Blinder Tunnel campaign since November 2025, targeting Iraqi critical infrastructure. The attackers impersonate the Dubai Airports IT department to deliver trojanized coding challenges that deploy ShelbyLoader V2 malware. The attack chain involves AppDomainManager hijacking and DLL sideloading techniques. The threat actor uses GitHub API infrastructure for command-and-control communications, including fallback channels via repositories and issues. Operational security mistakes linked this campaign to a separate credential harvesting operation targeting Israeli entities with conflict-themed Google Drive lures in mid-2026.
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.
A previously unseen ransomware family named Spirals was deployed in a double extortion attack against an IT services company in South Asia in June 2026. The Rust-based payload demonstrated sophisticated capabilities including defense evasion, encryption, lateral movement, and privilege escalation. Attackers gained initial access through a compromised internet-facing IIS web server via an ASP.NET web shell, moving rapidly to deploy ransomware within 24 hours. They established persistence using multiple tunneling tools, disabled endpoint security, harvested credentials through SAM hive and LSASS dumps, and deployed reverse-SOCKS proxies for covert command-and-control. The ransomware was distributed across the network using PsExec, encrypting files with AES-128 keys and threatening data publication within six days. The skilled execution suggests potential for wider campaigns, though the threat actor remains unidentified.
A ClickFix social engineering attack on an unmonitored endpoint led to a multi-stage intrusion affecting over 11 hosts. The infection chain began with a malicious HTA payload that silently installed an MSI package containing Potemkin, a custom loader with a deterministic DGA. Potemkin delivered RMMProject, a 4.4 MB Lua-scriptable RAT featuring browser credential theft with Chrome App-Bound Encryption bypass, hidden-desktop remote control, and 15 distinct task types. The attacker deployed EtherRAT, a Node.js backdoor resolving C2 addresses from Ethereum blockchain, and established a Cloudflare tunnel for persistent access. Hands-on-keyboard activity included battling Windows Defender through AMSI patches, registry modifications, and service termination, followed by lateral movement via WMIExec and SMBExec to deploy malware across the network and reach the domain controller.
Two distinct threat campaigns, SHADOW-AETHER-040 and SHADOW-AETHER-064, have been identified targeting government entities and financial organizations across Latin America using agentic artificial intelligence to conduct cyber intrusions. SHADOW-AETHER-040, a Spanish-speaking group, compromised six government entities in Mexico between December 2025 and January 2026, while SHADOW-AETHER-064, operating in Portuguese, targeted Brazilian financial institutions starting in April 2026. Both campaigns established SOCKS5 tunnels via ProxyChains and SSH, enabling AI agents to execute commands directly within victim networks. The AI agents dynamically generated hacking tools and scripts on-demand, reducing detection by signature-based security solutions. Despite tactical similarities including shared toolsets like Chisel, Neo-reGeorg, CrackMapExec, and Impacket, the campaigns appear to be separate entities distinguished primarily by language. These operations represent emerging cases of AI agents executing complete...
An exposed command and control server on RouterHosting infrastructure revealed an active Iranian-nexus intrusion campaign targeting twelve Omani government ministries. The operation primarily focused on the Ministry of Justice and Legal Affairs, deploying custom webshells that provided persistent access through April 2026. Over 26,000 user records containing judicial case data, committee decisions, and registry hives were exfiltrated. The attacker utilized ProxyShell exploits, DotNetNuke vulnerabilities, and custom Python scripts targeting Exchange servers, SQL databases, and Oracle systems. Infrastructure analysis revealed connections to spoofed Iranian diaspora media and censorship circumvention tools, with tactical overlaps indicating MOIS-linked groups such as APT34 and MuddyWater. The campaign specifically targeted judicial records, immigration systems, and citizen identity data across multiple government entities.
A series of attacks targeting financial organizations across Africa has been observed since July 2023. The threat actor, tracked as CL-CRI-1014, uses open-source and publicly available tools like PoshC2, Chisel, and Classroom Spy to establish attack frameworks, create tunnels for network communication, and perform remote administration. They forge file signatures to disguise their toolset and mask malicious activities. The attackers are suspected to be acting as initial access brokers, creating footholds in financial institutions to sell access on darknet markets. Their playbook includes lateral movement techniques such as creating remote services, executing through DCOM, and using PsExec. The threat actor also employs evasion methods like using packers and signing tools with stolen signatures.
