SLOWPULSE is a malware that was used by APT5 as early as 2020 including against U.S. Defense Industrial Base (DIB) companies. SLOWPULSE has several variants and can modify legitimate Pulse Secure VPN files in order to log credentials and bypass single and two-factor authentication flows.[1]

SLOWPULSE can log credentials on compromised Pulse Secure VPNs during the DSAuth::AceAuthServer::checkUsernamePasswordACE-2FA authentication procedure.4
SLOWPULSE can modify LDAP and two factor authentication flows by inspecting login credentials and forcing successful authentication if the provided password matches a chosen backdoor password.6
SLOWPULSE can insert malicious logic to bypass RADIUS and ACE two factor authentication (2FA) flows if a designated attacker-supplied password is provided.7
Reach is how much of ATT&CK this malware touches. Coverage is how well defended each thing it does is, as a median per technique rather than a total — a total would just restate the reach. Each figure is ranked against all 825 ATT&CK software entries only where that population actually spreads. Where most of the population shares one value, a percentile would rank the tie instead of the entity, so the raw value is shown and no rank is claimed.
Reach

Threat group161% tie · 22 values
61% of the population shares a single value across only 22 distinct values, so a percentile here would rank the tie, not the entity.
