- Lumma Stealer malware hides in a pretend Telegram Premium web site, launching with out consumer clicks
- Executable makes use of cryptor obfuscation to bypass most conventional antivirus scanning strategies solely
- Malware connects to actual Telegram servers whereas secretly sending stolen information to hidden domains
