ID:dos_outbound
Data type:IP
Severity:
Medium
MITRE ATT&CK:TA0040:T1498

Description

AlphaSOC detected outbound traffic patterns indicative of a Denial of Service (DoS) attack originating from within the network. DoS attacks aim to degrade or completely disrupt the availability of services, websites, or networks by flooding them with excessive traffic or requests. This finding may indicate that one or more internal systems may be participating in an attempt to overwhelm an external target's resources.

Impact

An outbound DoS attack may lead to service disruptions for the target. Additionally, it could indicate a compromise of internal systems, possibly being used as part of a larger strategy. This situation may result in blacklisting of the organization's IP addresses, affecting legitimate business operations.

Investigation and Remediation

Immediately identify and isolate the systems generating the DoS traffic. Conduct a thorough analysis of these systems to determine if they've been compromised or if an insider is intentionally launching the attack. Review logs, network traffic, and running processes. If malware is found, remove it and investigate how the infection occurred. If it's an insider action, address it according to company policies.
