Summary

  • Ivanti recently released a security advisory for two critical vulnerabilities in its Connect Secure, Policy Secure and ZTA gateway products.
  • If left unpatched, these vulnerabilities could enable a potential attacker to compromise enterprise infrastructure.
  • Palo Alto Networks has developed protections for these vulnerabilities and SHA signatures for known threat actor tooling.
  • We expect these signatures to grow in size and significance in the near term based on the high quality of the IoCs reported by third parties.
  • Unit 42 has also identified a cluster of activity in the wild using the RCE vulnerability.
  • Specifically, we observed a threat actor’s use of a Perl script to harvest credentials from an affected Ivanti appliance, likely to move laterally into the victim environment.
  • We have developed a set of YARA rules for these findings.
  • Customers should patch these vulnerabilities immediately and should contact Unit 42 or their Palo Alto Networks sales representative for more information.
