Loading threat actor…
APT19 is a threat actor also referred to in the provided content as ATG50, Black Vine, C0d0so0, Checkered Typhoon, Chlorine, Codoso, Codoso Team, Deep Panda, G0073, KungFu Kittens, PinkPanther, Red Gargoyle, Shell Crew, Sunshop Group, TG-3551, and WebMasters. The content describes APT19 using HTTP and a Port 22 malware variant to collect victim host information including hostname, CPU information, username, MAC address, IP address, and system architecture information. An HTTP malware variant established persistence via the Registry key HKCU\Software\Microsoft\Windows\CurrentVersion\Run\Windows Debug Tools-%LOCALAPPDATA%, while a Port 22 malware variant modified several Registry keys and registered itself as a service. The actor is also described as using HTTP for command-and-control communications, decrypting strings with single-byte XOR keys in an HTTP malware variant, attempting to get users to launch malicious attachments delivered via spearphishing emails, downloading and launching code within an SCT file, and using PowerShell including the -W Hidden WindowStyle parameter to conceal execution. The content also states that Deep Panda used PowerShell scripts to download and execute programs in memory without writing to disk, and separately notes that Deep Panda is known to utilize WMI for lateral movement.

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.
FireEye recently identified another targeted attack campaign that leveraged both the recently announced Internet Explorer zero-day, CVE-2013-1347, as well as recently patched Java exploits CVE-2013-2423 and CVE-2013-1493. ... If a visitor to one of these compromised website was running Internet Explorer 8.0 the malicious javascript would redirect them to a page at www[.]sunshop[.]com[.]tw hosting a CVE-2013-1347 exploit. ... The Internet Explorer (CVE-2013-1347) exploit code pulled down a “9002” RAT from another compromised site at hk[.]sz181[.]com.
The second jar file had a MD5 of 3fbb7321d8610c6e2d990bb25ce34bec and exploited CVE-2013-1493. ... The jar that exploited CVE-2013-1493 dropped a 9002 RAT with a MD5 of 42bd5e7e8f74c15873ff0f4a9ce974cd. ... The exploit site at sunshop[.]com[.]tw previously hosted a different malicious jar file on April 2, 2013. This jar file had a MD5 of 51aff823274e9d12b1a9a4bbbaf8ce00. It exploited CVE-2013-1493 and dropped a Poison Ivy RAT.
The java exploits were packaged as two different jar files. One jar file had a MD5 of f4bee1e845137531f18c226d118e06d7 and exploited CVE-2013-2423. The jar that exploited CVE-2013-2423 dropped a 9002 RAT with a MD5 of d99ed31af1e0ad6fb5bf0f116063e91f. This RAT connected to a command and control server at asp[.]homesvr[.]linkpc[.]net.
It is our hypothesis that these legitimate compromised sites were all compromised sometime after early November using CVE-2015-7501 [7,8] and publicly available exploit code [9].
