description: "The following analytic identifies the creation of GitHub Dependabot
|
|
alerts, which indicate potential vulnerabilities in the codebase. It detects this
|
|
activity by searching for logs with the \"create\" action and analyzing fields such
|
|
as affected package, severity, and fixed version. This detection is significant
|
|
for a SOC because it helps identify and address security risks in the codebase proactively.
|
|
If confirmed malicious, these vulnerabilities could be exploited by attackers to
|
|
gain unauthorized access or cause breaches, leading to potential data loss or system
|
|
compromise."

how_to_implement: You must index GitHub logs. You can follow the url in reference
|
|
to onboard GitHub logs.
