Loading threat actor…
APT5 is a China-attributed cyber-espionage threat actor, also known as Keyhole Panda, UNC2630, MANGANESE, Mulberry Typhoon, Bronze Fleetwood, and TG-2754. The group has targeted telecommunications, technology, government, and defense organizations, including the U.S. defense industrial base. Its operations are associated with intelligence collection and intellectual-property theft. APT5 has exploited internet-facing enterprise appliances, including Pulse Secure VPN products and Citrix ADC/Gateway systems, to gain initial access. Following VPN compromise, it has modified authentication components to log credentials and circumvent authentication flows, including MFA; maintained access; and deployed web shells. Reported operational behaviors include PowerShell execution, process injection, DNS-based command-and-control, proxying through multi-hop relay infrastructure, and file discovery. APT5 has also been associated with exploitation of CVE-2021-22893 and CVE-2022-27518.

Recent zero-day vulnerability in Pulse Secure VPN (CVE-2021-22893) ... FireEye published a blog detailing how the vulnerability (CVE-2021-22893) was being exploited by a China-linked APT group it tracks as UNC2630.
CVE-2022-27518 allows an unauthenticated remote attacker to perform arbitrary code execution on a Citrix appliance. NSA and Citrix reported active exploitation by APT5.
This detection identifies instances where Windows Explorer.exe spawns PowerShell or cmd.exe processes, particularly focusing on executions initiated by LNK files. This behavior is associated with the ZDI-CAN-25373 Windows shortcut zero-day vulnerability, where specially crafted LNK files are used to trigger malicious code execution through cmd.exe or powershell.exe. This technique has been actively exploited by multiple APT groups in targeted attacks through both HTTP and SMB delivery methods.
"By exploiting multiple Pulse Secure VPN weaknesses (CVE-2019-11510, CVE-2020-8260, CVE-2020-8243, and CVE-2021-22893), UNC2630 is said to have harvested login credentials..." ... "...advisory, warning businesses of active exploitation of five publicly known vulnerabilities by the Russian Foreign Intelligence Service (SVR), including CVE-2019-11510..."
This analytic identifies potential exploitation attempts of ProxyShell (CVE-2021-34473, CVE-2021-34523, CVE-2021-31207) and ProxyNotShell (CVE-2022-41040, CVE-2022-41082) vulnerabilities in Microsoft Exchange Server.
