Global Healthcare Giant

Within the first two weeks of deployment, Detect for AWS was quickly put to the test as a would-be attacker made their way into the environment.

‍Challenge

Trouble configuring custom detections within the SIEM for post-exploitation coverage
The rules are often bypassed, and investigation of the few alerts that fire, take up considerable time, hindering the team’s ability to respond quickly

Results

While monitoring over 1 million identities, users and services, within the environment, Detect for AWS spotted behavior closely resembling an attacker probing the footprint for weaknesses, and their SIEM did not.
Detect for AWS then observed the malicious principal attempting to disable security tools within the environment as a means to establish persistence

When a SIEM Just Isn’t Enough: Squashing a Sophisticated Cyberattack

Challenge

The global healthcare organization was experiencing challenges with its existing security information and event management (SIEM) tools in effectively identifying internal threats. Custom rules for post-exploitation coverage within the SIEM often bypassed significant threats due to the inability of the SIEM to manage a large volume of unprioritized alerts from pervasive reconnaissance activities and attempted privilege escalations.

Solution

To combat these cybersecurity issues, the organization selected the Vectra AI Detect platform for its AWS footprint, aiming to provide seamless threat detection within their cloud infrastructure. Within the first two weeks of deployment, the platform detected a would-be attacker attempting to infiltrate the environment by stealing credentials and probing the footprint for weaknesses.

Customer benefits

With Vectra AI, the organization was able to monitor over 1 million identities, users, and services, promptly detecting and putting a halt to the attacker's behaviors. Vectra Detect's AI-driven analysis meant the SOC team could quickly respond to elevated threats, drastically reducing the number of accounts requiring attention. The platform also provided the team with valuable insights into principal activities, enabling them to effectively quarantine the account and stop the attack in its tracks.
