⚠️ Risk & Real-World Impact
Worst Case
Complete bot takeover allowing attacker to impersonate bot, access all bot privileges, perform DDoS attacks, and potentially compromise connected systems or user data.
Likely Case
Bot token theft leading to bot impersonation, unauthorized actions using bot permissions, and potential service disruption.
If Mitigated
Limited impact through proper access controls and monitoring, with potential for detection before full compromise.
🎯 Exploit Status
Exploitation requires ability to load malicious modules and execute commands through the bot framework.
