Threats Affecting Uruguay

During a targeted intrusion investigation in June 2026, investigators uncovered GoCaracal, a previously undocumented modular framework written in Go. This sophisticated toolkit exists in two operational profiles: a lightweight implant for establishing access and delivering payloads, and an extended build for sustained intelligence collection with capabilities including keylogging, browser credential theft, WebRTC remote desktop, and SOCKS5 proxying. Analysis of 249 samples traced the framework's evolution from January to July 2026, revealing active development and maturation. A notable innovation includes an Ethereum smart-contract fallback mechanism enabling operators to update C2 infrastructure without redeploying malware. The activity targeted a Venezuelan communications organization using Spanish-language financial lures, weaponized SVG files, and delivery methods consistent with established tradecraft. GoCaracal was deployed alongside an updated Bandook variant, suggesting the new framework currently ...

A weakness has been identified in La Nacion App 10.2.25 on Android. This impacts an unknown function of the file source/app/lanacion/clublanacion/BuildConfig.java of the component app.lanacion.activity. Executing a manipulation of the argument API_KEY_WEBSOCKET_CV can lead to unprotected storage of credentials. The attack can only be executed locally. A high complexity level is associated with this attack. The exploitability is said to be difficult. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

UAT-9244, a China-nexus advanced persistent threat actor, has been targeting critical telecommunications infrastructure in South America since 2024. The group employs three new malware implants: TernDoor, a Windows-based backdoor variant of CrowDoor; PeerTime, an ELF-based backdoor using BitTorrent protocol; and BruteEntry, a brute force scanner for SSH, Postgres, and Tomcat servers. UAT-9244 uses dynamic-link library side-loading, scheduled tasks, and registry modifications for persistence. The group is closely associated with FamousSparrow and Tropic Trooper, sharing similar tooling and tactics. Their infrastructure includes multiple command and control servers and operational relay boxes for scanning and brute-forcing activities.
