PHOREAL

PHOREAL is a malware family associated with the Vietnam-aligned espionage threat actor APT32, also known as OceanLotus. Reporting cited in the content identifies PHOREAL as one of APT32’s signature malware payloads, alongside WINDSHIELD, KOMPROGO, and SOUNDBITE, and places its use in APT32 intrusions targeting private-sector organizations, foreign governments, dissidents, journalists, and entities with business interests in Vietnam. Specific victim sectors mentioned in the supporting content for APT32 activity include manufacturing, consumer products, hospitality, banking, media, network security, and technology infrastructure, with examples including 2016 targeting of U.S. consumer products organizations.

Capabilities directly attributed to PHOREAL in the content include command-and-control over ICMP, Windows Registry manipulation, and creation of a reverse shell. The content also notes that APT32 backdoors modified the Windows Registry to store backdoor configuration, which is consistent with PHOREAL’s listed Registry manipulation capability, but no more specific registry paths or configuration details are provided for PHOREAL itself.

The broader APT32 intrusion tradecraft described in the source material includes spear-phishing emails delivering ActiveMime ".mht" lure documents disguised as ".doc" files that entice victims to enable macros, after which multiple payloads are downloaded from remote servers. However, the content does not explicitly state that PHOREAL itself is the payload delivered by that vector in every case. No PHOREAL-specific hashes, filenames, domains, IPs, or other unique indicators of compromise are provided in the content.

MITRE ATT&CK

Techniques & procedures

12 distinct techniques documented for this family, organized by ATT&CK tactic.

Initial Access

1 technique
T1566.001Spearphishing AttachmentEvidence2

“APT32 has leveraged ActiveMime files that employ social engineering methods to entice the victim into enabling macros… APT32 actors continue to deliver the malicious attachments via spear-phishing emails.”

Execution

5 techniques
T1053.005Scheduled TaskEvidence1

“the malicious macros created two named scheduled tasks as persistence mechanisms for two backdoors on the infected system.”

T1059.001PowerShellEvidence1

“delivered as a multi-stage PowerShell script… delivered as shellcode in a PowerShell script…”

T1059.003Windows Command ShellEvidence3

The content repeatedly describes use of cmd.exe, cmd /c, Windows command shell, and xp_cmdshell to execute commands, run payloads, launch binaries, perform reconnaissance, persistence, cleanup, and ransomware actions. Examples include: 'Sandworm Team used the xp_cmdshell command in MS-SQL', 'APT41 used cmd.exe /c to execute commands on remote machines', and many malware families 'can use cmd.exe to execute commands on a compromised host.' | Many entries explicitly state malware 'can create a reverse shell' or 'launch a remote shell,' including 4H RAT, AuditCred, BLACKCOFFEE, Carbanak, DarkComet, Exaramel for Windows, PlugX, QuasarRAT, and ZxShell.

T1059.005Visual BasicEvidence1

“The Base64 encoded ActiveMime data also contained an OLE file with malicious macros.”

T1204.002Malicious FileEvidence1

“APT32 has leveraged ActiveMime files that employ social engineering methods to entice the victim into enabling macros.”

Persistence

2 techniques
T1053.005Scheduled TaskEvidence1

“the malicious macros created two named scheduled tasks as persistence mechanisms for two backdoors on the infected system.”

T1112Modify RegistryEvidence6

The content repeatedly describes threat actors and malware modifying, creating, deleting, or storing data in Windows Registry keys and values for persistence, configuration storage, defense evasion, credential access, privilege escalation, and execution.

Privilege Escalation

1 technique
T1053.005Scheduled TaskEvidence1

“the malicious macros created two named scheduled tasks as persistence mechanisms for two backdoors on the infected system.”

Stealth

2 techniques
T1036MasqueradingEvidence2

“installed one backdoor as a persistent service with a legitimate service name… Another backdoor used an otherwise legitimate DLL filename…”

T1218.005MshtaEvidence1

“This second task ran ‘mshta.exe’ every 50 minutes…”

Defense Impairment

1 technique
T1112Modify RegistryEvidence6

The content repeatedly describes threat actors and malware modifying, creating, deleting, or storing data in Windows Registry keys and values for persistence, configuration storage, defense evasion, credential access, privilege escalation, and execution.

Command and Control

3 techniques
T1095Non-Application Layer ProtocolEvidence3

"Anchor has used ICMP in C2 communications." / "COATHANGER uses ICMP for transmitting configuration information..." / "PHOREAL communicates via ICMP for C2." / "Regin ... can use ICMP to communicate between infected computers." / "Cobalt Strike can be configured to use TCP, ICMP, and UDP for C2 communications."

T1105Ingress Tool TransferEvidence2

“Upon execution, the initialized file downloads multiple malicious payloads from remote servers.”

T1219Remote Access ToolsEvidence1

4H RAT has the capability to create a remote shell. AuditCred can open a reverse shell on the system to execute commands. PlugX allows actors to spawn a reverse shell on a victim. QuasarRAT can launch a remote shell to execute commands on the victim’s machine.
