Description
CISA received a benign 32-bit Windows executable file, a malicious dynamic-link library (DLL) and an encrypted file for analysis from an organization where cyber actors exploited vulnerabilities against Zimbra Collaboration Suite (ZCS). Four CVEs are currently being leveraged against ZCS: CVE-2022-24682, CVE-2022-27924, CVE-2022-27925 chained with CVE-2022-37042, and CVE-2022-30333. The executable file is designed to side-load the malicious DLL file. The DLL is designed to load and Exclusive OR (XOR) decrypt the encrypted file. The decrypted file contains a Cobalt Strike Beacon binary. The Cobalt Strike Beacon is a malicious implant on a compromised system that calls back to the command and control (C2) server and checks for additional commands to execute on the compromised system.
For more information on cyber actors exploiting vulnerabilities in ZCS, see joint CSA: Threat Actors Exploiting Multiple CVEs Against Zimbra Collaboration Suite.

Description
This artifact is a malicious 32-bit DLL file loaded by “vxhost.exe” (4109ac08bdc8591c7b46348eb1bca85d). This file is designed to search and load an encrypted file “%current directory%bin.config” (be2b0c387642fe7e8475f5f5f0c6b90a) if installed on the compromised system. It decrypts the file using the hard-coded XOR key “0x401”. The decrypted binary contains a Cobalt Strike Beacon DLL that has an embedded shellcode inside of the MZ header. It copies the Cobalt Strike Beacon DLL into a buffer and executes the shellcode.

Description
This file is decrypted and executed by “vftrace.dll” (058434852bb8e877069d27f452442167). This file is a 32-bit Portable Executable (PE) DLL that has an embedded shellcode inside of the MZ header, which is located at the start of the file. When executed, the shellcode decrypts an embedded beacon payload using a single-byte XOR key 0xC3. It executes the entry point of the decrypted payload in memory at runtime. The decrypted payload has been identified as a Cobalt Strike Beacon implant. During the execution, it decodes its configuration using a single-byte XOR key 0x4f. The configuration contains the, RSA public key, C2, communication protocol, and more. The parsed configuration data for the Cobalt Strike Beacon implant is displayed below in JSON format:

–End configuration in the Cobalt Strike Beacon–
It is designed to use a JavaScript library jQuery malleable C2 profile for communication to evade detection. It attempts to send a GET request to its C2 server with metadata in the cookie header “__cfduid” that contains information about the compromised system such as, username, computer name, operating system (OS) version, the name of the malware executing on the victim’s system, and other information. The metadata in the cookie header is encrypted and encoded.
Displayed below is the RSA public key used to encrypt the metadata before it is encoded using NetBios (uppercase) and base64 encoding algorithm:

Analysis indicates that the C2 server will respond to the above HTTP GET request with encrypted data that contains commands, which the malware will decrypt and execute to perform additional functions. The C2 server response payload was not available for analysis.
Displayed below are sample functions built into the malware:
–Begin commands–
Make and change directory
Copy, move, remove files to the specified destination
Download and upload files
List drives on victim’s system
Lists files in a folder
