Citigroup, Idaho, and Build-a-Bear Launched a Coordinated Attack on Me
TL;DR
A coordinated phone-fraud attack involving Citigroup, Idaho, and Build-A-Bear targeted a VoIP server, exploiting it for International Revenue Share Fraud. The incident highlights vulnerabilities in corporate networks due to bot infections.
✦ Why It Matters
Ensure your network security protocols are robust to prevent bot infections and potential fraud.
Key Takeaways
- Regularly monitor your network for unauthorized access.
- Use the API to check for recorded attacks on your systems.
- Educate employees about phishing and malware risks.
- Isolate any rogue machines immediately to protect your network.
How It Works
The attack exploited the VoIP server by using it as an open relay to dial premium-rate numbers. Each compromised machine in the botnet received commands to target the same number, indicating centralized control.
This method allows attackers to profit from calls made through infected networks.
