eSentire in Action: The Kaseya Zero-Day Attacks

In this video, eSentire’s Elite Threat Hunter, Spence Hutchinson, reviews the Kaseya VSA supply chain cyberattacks and how eSentire’s Threat Response Unit (TRU) & Security Operations Center (SOC) were able to quickly respond on customer’s behalf and notify Kaseya of the breaches.

In both cyberattacks threat actors leveraged zero-day vulnerabilities. In 2018 they pushed Cryptomining malware and in 2021 they deployed Ransomware to Kaseya VSA customers. In both cases, eSentire’s BlueSteel Machine Learning Engine was able to identify malicious Powershell commands being executed in customer environments that traditional security controls would have missed. eSentire’s actions to detect, respond and remediate these zero-day attacks for our impacted customers demonstrate the importance of having a Managed Detection and Response (MDR) service that goes beyond alerting and host isolation to deliver complete and robust response.

Watch this video for more information on the Kaseya zero-day attacks, details on the actions of our elite threat hunters and the importance of eSentire Multi-signal MDR for detecting & responding zero-day attacks.
