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...

A highly sophisticated multi-stage post-exploitation framework targeting organizations in the Middle East and EMEA financial sectors exploits legitimate digitally signed Intel utilities through .NET AppDomainManager mechanism abuse. The attack leverages trusted binary proxy execution, bypassing EDR and antivirus solutions through JIT-based memory execution and sandbox evasion using computational delays and cryptographic key derivation loops. Initial access occurs via spear-phishing with Arabic-language decoys impersonating Saudi government documents. Once executed, the framework establishes command-and-control communication through Amazon CloudFront CDN domain fronting, employing reflective DLL loading, direct syscall usage, and anti-forensic memory cleanup techniques. The modular plugin-based architecture demonstrates capabilities consistent with advanced persistent threat actors, featuring sophisticated evasion mechanisms including PEB-based API resolution, custom PE export walking, and heap-walking cont...

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.
