Pyramid of Pain Overview:The Pyramid of Pain categorizes indicators based on how difficult they are for attackers to alter:
Hash Values (Low Impact):Attackers can easily change a file's hash by altering even a single byte, rendering this indicator obsolete.
IP Addresses, Domain Names (Moderate Impact):Slightly harder to change than hash values but still relatively easy for attackers to adapt.
TTPs (High Impact):Tactics, Techniques, and Procedures are the most difficult for attackers to alter because they involve the fundamental ways attackers operate. Detecting and responding to TTPs can significantly disrupt an attacker’s strategy.
Why Hash Values Are Least Effective:
Ease of Evasion:Attackers can quickly generate new hash values by modifying files, making it a weak indicator for continuous monitoring.
Short Lifespan:Once detected and blocked, a hash value is of limited use because attackers can simply recompile or pack the malware to create a new hash.
David Bianco's Pyramid of Pain Blog Post:Bianco’s original post and related materials provide a deep dive into why hash values are the least effective and why focusing on higher-level indicators is more impactful for security operations.
Threat Intelligence Reports:Many reports emphasize the importance of focusing on TTPs over simpler indicators like hash values to build a more resilient detection and response strategy.
