https://bit.ly/3QEL7nz - 🔍 Operation Triangulation Stealth Techniques Unveiled Operation Triangulation utilized TriangleDB as its main implant. This operation is noteworthy for the extreme stealth employed by the threat actors involved. #CyberSecurity #TriangleDB 🖥 Understanding the Infection Chain Malicious iMessage attachments trigger a series of exploits, leading to the launch of TriangleDB. The chain has two validator stages: "JavaScript Validator" and "Binary Validator". These validators aim to assess if the target device is for research, ensuring the exploits remain hidden. #InfoSec #ThreatDetection 📱 Validators at Work The JavaScript validator begins its operation through an invisible iMessage attachment that aims to open a specific URL. The validator performs various checks and features a unique fingerprinting technique using Canvas Fingerprinting. On the other hand, the Binary Validator, a Mach-O binary file, assesses if the device has been jailbroken, scans for specific processes, and more. Interestingly, some components hint at targeting macOS devices. #ValidatorTech #CyberSafety 🔒 Stealth Beyond Validators Apart from validators, the threat actor shows stealth in how they interact with the TriangleDB implant. They meticulously retrieve and delete logs that could trace back to the malware or infection chain. These logs include crash log files and database files potentially linking back to the attacker. #DataProtection #StealthOps 🎙 Invasive Microphone Module A microphone-recording module, named "msu3h," activates only if the device battery is above 10%. It can be configured to record sound only under specific conditions, showcasing the level of detail the attacker implemented. #PrivacyConcerns #SoundSpying 🗝 Exfiltrating Key Data Despite TriangleDB's capabilities, an additional keychain exfiltration module was employed. Additionally, there were SQLite stealing modules that could extract application data from various databases, indicating the attackers' interest in app data, including popular platforms like WhatsApp, SMS, and Telegram. #DataTheft #KeychainSecurity 🌍 Location Monitoring An advanced location-monitoring module was observed that utilizes GSM-related data to estimate the victim's location when GPS is not accessible. #LocationTracking #GSM 🔚 Concluding Insights The actors behind Operation Triangulation went to great lengths for stealth, from using validators to advanced location tracking. Their deep understanding of iOS and possibly macOS systems underscores the sophistication of the attack. Operation Triangulation, despite its stealthy approach, has been fully analyzed, revealing the extent of its techniques. For a deeper dive into how this operation was neutralized, experts will share insights in an upcoming SAS conference.
