DangerousPassword Attacks Targeting Windows, macOS, and Linux Software Developers

Python-essentially based entirely malware targets Windows, linux, and macOS and is presumed to be old fashioned by dangerous password attack groups, incessantly identified as Crypto mimics.

This group has been energetic since June 2019 and employs varied tactics to elevate malware to the sufferer’s machine.

JPCERT/CC released the newest article about attacks confirmed by the campaigns and shared their diagnosis narrative.

Focusing on Windows

For the reason that attack vector of this advertising campaign is unknown, the infection scamper together with the circulation after the execution of the malware is expounded to that of the Linkedin attack by this group.

In the foundation, the malware file  builder.py of the Python module is dropped on the sufferer machine, which downloads additional malware as soon because it will get done by the client.

The malware downloads and runs additional MSI files externally using a Powershell script that’s dropped after the execution.

The malware communicates with the C2 server every minute and is to blame for the download and execution of additional malware.

Apart from, the secondary sample of the MSI file downloaded by the Powershell script encodes the client name, OS, direction of knowledge, etc. of the contaminated machine with BASE64 and sends it to the C2 server.

Also, it makes use of PythonHTTPBackdoor malware with straightforward instructions to develop the attack, which has a feature to detect the OS ambiance, and the instructions done are a minute bit numerous relying on the ambiance.

Linux and macOS:

In macOS and Linux environments, the builder.py file is decoded and saved as a log. tmp, and done as a Python file.

The patron ID and OS ambiance knowledge ​​are despatched to the C2 server every minute and decoded with BASE64, saving it as tmp.py.

PythonHTTPBackdoor has ROT13-encoded git-linked strings in the ask string and generated file name, proper admire a log. tmp, which indicates that Git is old fashioned. That you must possibly possibly presumably spy that it is miles focusing on developers.

As an illustration, the notify identity 501 is old fashioned to retrieve the community and direction of knowledge, and 502 is old fashioned to develop the instructions in Windows, Linux, and macOS machines.

In the same vogue, Mach-O malware JokerSPYand node.js malware are being old fashioned by this attack group to target the victims.
