THE ERA OF SEMANTIC SECURITY: COMPUTER USE AGENTS AND THE END OF SIGNATURES

Summary from the TLDR InfoSec newsletter

Local computer use agents fundamentally shift the endpoint security industry because a properly functioning agent can be indistinguishable from a malicious agent or attacker, diminishing the value of signatures. A previous analogue is the adoption of PowerShell by both attackers and sysadmins, which made context necessary to distinguish attacks from standard use. Successful organizations will need to build contextual defense systems rather than trying to push back on agent adoption.
