Raw IP connections	`http://1.2.3.4` style URLs
Dangerous functions	`eval()`, `exec()`, `os.system()`, `subprocess(shell=True)`
Hidden files	Dotfile creation in unexpected places
Env exfiltration	Reading `.env`, API keys sent outbound
Obfuscated URLs	rentry.co, pastebin, hastebin redirectors
Fake dependencies	References to non-existent packages
Data exfil endpoints	webhook.site, requestbin, etc.
Crypto mining	xmrig, stratum, mining pool references
Password archives	Password-protected zip/tar downloads
