VectraGPT-PCAP & Vectra Analysis

Example

Upon receiving a Vectra alert indicating a potential command and control (C&C) activity, VectraGPT analyzes the alert details and the associated network traffic to identify the specific nature of the threat, such as external remote access or hidden tunnels.

Scenario

A cybersecurity analyst receives a high-severity alert from Vectra indicating suspicious C&C behavior. Using VectraGPT, the analyst is able to quickly identify the alert as related to hidden HTTPS tunneling, correlating it to MITRE ATT&CK techniques T1071 (Application Layer Protocol) and T1572 (Protocol Tunneling), and receives guidance on investigating the alert further.

Example

VectraGPT examines PCAP files to detect anomalies or signs of malicious activities, such as malware communication or data exfiltration attempts, offering insights into the methods and protocols used by attackers.

Scenario

In the case of a suspicious file transfer detected by Vectra, a security professional uses VectraGPT to analyze the corresponding PCAP file. VectraGPT identifies the transfer as a data exfiltration attempt using a hidden HTTP tunnel, provides a detailed breakdown of the malicious traffic, and suggests steps for containment and further analysis.

Example

VectraGPT provides recommendations for leveraging integrated EDR systems, like Microsoft Sentinel, to correlate Vectra alerts with endpoint data, enabling a more comprehensive understanding of an incident's impact and scope.

Scenario

Following a Vectra alert about lateral movement within the network, a user employs VectraGPT to integrate findings with Microsoft Sentinel. VectraGPT guides the user in correlating network and endpoint data to identify affected systems and user accounts, facilitating a targeted response to the incident.
