SACK Panic is a DDoS technique that targets system availability by overloading infrastructure. This page explains the attack, mitigation capabilities, and the role of WEDOS Global.
Description
Exploits TCP Selective Acknowledgment (SACK) vulnerabilities to crash the target.
Mitigation Capabilities
Anycast: No, doesn’t mitigate protocol-level vulnerabilities.
NGINX Proxy: No, not applicable for TCP-level issues.
HAProxy: No, irrelevant for SACK vulnerabilities.
IDS Suricata: Partially, detects unusual TCP SACK traffic.
WAF: No, not suitable for protocol-layer vulnerabilities.
OWASP Rules: No, unrelated to SACK threats.
Complex anycast solution – WEDOS Global (or Cloudflare for example): No, doesn’t mitigate SACK-specific vulnerabilities.
Solutions
Patch systems to address SACK vulnerabilities.
