Category: MALICIOUS - The campaign has clearly malicious intent, like infostealers. Campaign: 2026-05-telethon-pro-safe Reasons (based on the campaign): - rat - The package overrides the install command in setup.py to execute malicious code during installation. - exfiltration-credentials - exfiltration-browser-data - The package contains code to execute remote commands (probably limited to a specific set) on the victim's machine. - The package contains code to detect if it is running in a sandbox environment. - The package contains code to exfiltrate basic data from the system, like IP or username. It has a limited risk. - infostealer - obfuscation
