MOVEit Certificate Store Access Failure
This detection identifies potential exploitation attempts of the CVE-2024-5806 vulnerability in Progress MOVEit Transfer. It looks for log entries indicating failures to access the certificate store, which can occur when an attacker attempts to exploit the authentication bypass vulnerability. This behavior is a key indicator of attempts to impersonate valid users without proper credentials. While certificate store access failures can occur during normal operations, an unusual increase in such events, especially from unexpected sources, may indicate malicious activity.

how_to_implement: The MOVEit logs must be collected in Splunk. Currently, there is no TA available for MOVEit. Modify the analytic as needed to match the log format of your environment.
known_false_positives: False positives may occur, therefore utilize the analytic as a jump off point to identifiy potential certificate store errors.

Indicators
Each row is a field, operator, and value that the rule matches. The corpus column counts how many other rules in the catalog look for the same combination: high numbers point to widely-used, community-vetted indicators. Blank or 1 shows that the indicator is specific to this rule.
| Field | Kind | Values |
|---|---|---|
sourcetype | eq |

Search terms
Bare-string tokens in the SPL search body. Splunk matches each token against _raw (the untyped raw event text) anywhere it appears, not against a specific field. These don't surface in the Indicators table because they aren't predicates on a known field.
