Initial Access Vectors

CISA responded to the organization’s request, finding nation-state APT actors on the network from January 2023 via two initial access vectors.

Here below, we have mentioned the two initial vectors:-

  • Initial Access Vector 1: CVE-2022-47966 allowed APT actors to breach the Zoho ManageEngine ServiceDesk Plus web server hosting.
  • Initial Access Vector 2: To access the firewall device of the organization, CVE-2022-42475 was exploited by the APT actors.

Besides this, multiple APT actors using similar tactics were found by the CISA and partners. It’s been found that threat actors frequently scan for and exploit vulnerabilities in internet-facing devices to expand access or serve as malicious infrastructure, particularly:-

  • Firewalls
  • VPNs
  • Edge network infrastructure
