EDRSilencer is a red team tool that has been observed being abused by threat actors to disrupt endpoint detection and response (EDR) solutions. It achieves this by blocking EDR traffic, making it harder for EDR solutions to identify and respond to malicious activity. This tool was discovered by Trend Micro, they also found that EDRSilencer can be used to conceal malicious activity, allowing threat actors to operate more stealthily. This represents a worrying development in the field of cybersecurity, with threat actors increasingly focusing on evading detection by EDR solutions.
