  • Volexity@Volexity

    .@Volexity has discovered in-the-wild exploitation of a #zeroday exploit chain targeting Ivanti Connect Secure VPN appliances (CVE-2026-104935). Beginning October 3, a previously unknown threat actor, UTA0576, chained three vulnerabilities to gain unauthenticated root-level code execution on a fully patched device. Notably, UTA0576 deployed no malware or web shell. Instead, the threat actor re-exploited the device for every command it ran and tampered with logs to cover its tracks, evading Ivanti’s Integrity Checker Tool. Using its #Volcano memory analysis platform, Volexity analyzed the compromised device’s memory to uncover the full exploit chain and the attacker’s post-exploitation activity, which focused on credential theft, Active Directory reconnaissance, and data exfiltration. Volexity reported these findings to Ivanti through coordinated disclosure. Read the full analysis, including detection guidance and IOCs, in our blog post here: https://www.volexity.com/blog/2026/10/13/a-series-of-unauthenticated-events-chained-exploitation-of-ivanti-connect-secure-zero-days/ #DFIR #threatintel #memoryforensics

    🚨 Our Ivanti Connect Secure decoys caught pre-disclosure exploitation we assess as CVE-2026-104935. Activity was recorded on Oct 1st, twelve days before Ivanti’s advisory, on both our public honeypots and customer instances. The exploit ran an unauthenticated bypass to plant an implant that runs entirely in memory and writes no files to disk - which is potentially why the advisory ships with no reliable IOCs.

    🚨 IVANTI CONNECT SECURE ZERO-DAY CHAIN EXPLOITED TO STEAL CREDENTIALS (CVE-2026-104935) Ivanti disclosed a new Connect Secure (ICS) VPN flaw on Oct 13, 2026 and says it is aware of limited exploitation in the wild. CISA added it to the KEV catalog the same day. Volexity published the incident behind it. What Volexity found: • An unknown actor it tracks as UTA0576 exploited the chain from Oct 3, 2026 against a then fully patched appliance (22.8R2.4) • Auth bypass + race-condition RCE (both CVE-2026-104935), chained with a separate privilege-escalation bug for root • No backdoor or web shell: the actor re-ran the exploit for every command, then deleted log entries • Post-exploitation: LDAP/AD credential theft, searches for LAPS passwords and BitLocker recovery keys, password spraying, packet capture Fix: follow Ivanti's advisory for your appliance's fixed build (the CVE record lists 22.8R2.5 and 25.1.3.0/25.1.3.1 as unaffected). Ivanti says a fix for the privilege-escalation bug is still coming. CISA federal due date: Oct 16, 2026. ⚠️ Analyst Note: A clean Integrity Checker result does not rule this out. The chain patches code in memory only and restores state, so Volexity says memory and network forensics are needed. Watch for heavy requests to /dana-na/auth/url_default/welcome.cgi with an X-DSCGI-PATH header that doesn't match the URL. No victim count is established, and Volexity's attribution (criminal, low confidence) is tentative.
