MITRE ATT&CK

Techniques & procedures

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

Initial Access

2 techniques

T1566PhishingEvidence1

We analyzed a new malware, which we attribute to the APT34 advanced persistent threat (APT) group, that was involved in a phishing attack.

T1566.001Spearphishing AttachmentEvidence1

In August, our threat hunting activities identified a malicious document we investigated to have been used during a targeted phishing attack by the group.

Execution

3 techniques

T1053.005Scheduled TaskEvidence1

The malicious document is responsible for dropping a new malware we have called Menorah ... and for creating a scheduled task for persistence.

T1059Command and Scripting InterpreterEvidence2

Command starts with “+sp” – Create a process and exfiltrate its output | The malware creates a new process via a function call to the CreateProcess function. The process’ output is read using the PeekNamedPipe and Read methods, and then exfiltrated to the C2 server

T1059.005Visual BasicEvidence1

The malicious document contains hidden macros responsible for dropping a .NET malware into the <%ALLUSERSPROFILE%\Office356> directory, naming it Menorah.exe.

Persistence

1 technique

T1053.005Scheduled TaskEvidence1

The malicious document is responsible for dropping a new malware we have called Menorah ... and for creating a scheduled task for persistence.

Privilege Escalation

1 technique

T1053.005Scheduled TaskEvidence1

The malicious document is responsible for dropping a new malware we have called Menorah ... and for creating a scheduled task for persistence.

Stealth

3 techniques

T1036MasqueradingEvidence1

It then creates a scheduled task named "OneDriveStandaloneUpdater" to execute the Menorah.exe malware.

T1480Execution GuardrailsEvidence1

It creates a mutex called “115CF7F6-69B4-49EE-B453-BAF00531AC52” to ensure that only one copy of the malware is running at a single time

T1497Virtualization/Sandbox EvasionEvidence1

The regular check ensures the routine’s and components’ stealth, and detects if the malware is in an analytic environment like a sandbox.

Discovery

4 techniques

T1033System Owner/User DiscoveryEvidence2

The hostname and username are retrieved, and then the malware computes the MD5 hash of the concatenation between these two values

T1082System Information DiscoveryEvidence2

It extracts the hostname and the username and computes a hash that identifies the infected machine.

T1083File and Directory DiscoveryEvidence2

Command starts with “+fl” – List files and subdirectories from a directory

T1497Virtualization/Sandbox EvasionEvidence1

The regular check ensures the routine’s and components’ stealth, and detects if the malware is in an analytic environment like a sandbox.

Command and Control

4 techniques

T1001Data ObfuscationEvidence1

The server response has the following structure “[@<Value>@]”. The extracted value is Base64-decoded and decrypted using the XOR operator.

T1071.001Web ProtocolsEvidence2

The C2 server “http[:]//tecforsc-001-site1.gtempurl[.]com/ads.asp” is hard-coded in the malware | The process sets the interval of a timer to 32 seconds, which ensures a continuous communication with the C2 server... The encoded string that identifies the host is exfiltrated to the C2 server via a POST request.

T1105Ingress Tool TransferEvidence2

If the command ID is 2, then the malware creates a file that is populated with content received from the C2 server

T1132Data EncodingEvidence1

The malware continues to encode the string into ASCII then calculates for the MD5 hash... XOR with a hardcoded string and encoded in Base64...

Exfiltration

1 technique

T1041Exfiltration Over C2 ChannelEvidence2

The encoded string that identifies the host is exfiltrated to the C2 server via a POST request... The process’ output is read using the PeekNamedPipe and Read methods, and then exfiltrated to the C2 server... The file name, along with the content that is Base64-encoded, is transmitted to the C2 server

APT34 Deploys Phishing Attack With New Malware | Trend Micro (US)

A newly identified .NET malware attributed to APT34 and delivered via a phishing document. It establishes persistence via a scheduled task, fingerprints the victim machine, communicates with a C2 server, executes shell commands, lists files and directories, uploads selected files, and downloads additional files. It is described as designed for cyberespionage.
