Yesterday, Ivanti released security updates for two vulnerabilities affecting multiple products, including Ivanti Connect Secure, Ivanti Policy Secure, and Ivanti Neurons for Zero Trust Access (ZTA) gateway. They noted having observed exploitation in-the-wild leading CISA to issue an alert as well as include them in its Known Exploited Vulnerability (KEV) catalog.
Ivanti Connect Secure has a track record of being exploited by various attackers, including advanced persistent threat (APT) groups, ransomware affiliates, and opportunistic threat actors. Due to the history of exploitation of these devices, coupled with the water sector’s propensity to be targeted by sophisticated threat groups, members are strongly encouraged to install the available patches promptly. Find the full Ivanti advisory here.
If your utility uses any of the Ivanti products included in this advisory, the following hunting guidance from CISA is highly encouraged:
- Conduct threat hunting actions:
- Run the In-Build Integrity Checker Tool (ICT). Instructions can be found here.
- Conduct threat hunt actions on any systems connected to—or recently connected to—the affected Ivanti device.
- If threat hunting actions determine no compromise:
- Factory reset the device and apply the patch described in Security Advisory Ivanti Connect Secure, Policy Secure & ZTA Gateways (CVE-2025-0282, CVE-2025-0283).
- Monitor the authentication or identity management services that could be exposed.
- Continue to audit privilege level access accounts.
- If threat hunting actions determine compromise:
- Report to CISA and Ivanti immediately to start forensic investigation and incident response activities.
- Disconnect instances of affected Ivanti Connect Secure products.
- Isolate the systems from any enterprise resources to the greatest degree possible.
- Revoke and reissue any connected or exposed certificates, keys, and passwords, to include the following:
- Reset the admin enable password.
- Reset stored application programming interface (API) keys.
- Reset the password of any local user defined on the gateway, including service accounts used for auth server configuration(s).
- If domain accounts associated with the affected products have been compromised:
- Reset passwords twice for on premise accounts, revoke Kerberos tickets, and then revoke tokens for cloud accounts in hybrid deployments.
- For cloud joined/registered devices, disable devices in the cloud to revoke the device tokens.
- After investigation, fully patch and restore system to service.
