The Chinese country-condition team dubbed Alloy Taurus is working with a Linux variant of a backdoor called PingPull as very well as a new undocumented instrument codenamed Sword2033.
That is in accordance to conclusions from Palo Alto Networks Device 42, which uncovered new malicious cyber action carried out by the team concentrating on South Africa and Nepal.
Alloy Taurus is the constellation-themed moniker assigned to a threat actor that’s acknowledged for its assaults targeting telecom firms considering that at minimum 2012. It is really also tracked by Microsoft as Granite Hurricane (previously Gallium).
Final month, the adversary was attributed to a campaign termed Tainted Really like concentrating on telecommunication vendors in the Middle East as component of a broader operation referred to as Soft Mobile.
New cyber espionage attacks mounted by Alloy Taurus have also broadened their victimology footprint to include fiscal establishments and government entities.
PingPull, 1st documented by Device 42 in June 2022, is a remote access trojan that employs the Internet Command Message Protocol (ICMP) for command-and-regulate (C2) communications.
The Linux taste of the malware boasts of identical functionalities as its Windows counterpart, enabling it to carry out file functions and operate arbitrary instructions by transmitting from the C2 server a solitary upper case character between A and K, and M.
“On execution, this sample is configured to talk with the area yrhsywu2009.zapto[.]org above port 8443 for C2,” Device 42 claimed. “It takes advantage of a statically joined OpenSSL (OpenSSL .9.8e) library to interact with the domain about HTTPS.”
Curiously, PingPull’s parsing of the C2 recommendations mirrors that of the China Chopper, a web shell extensively utilised by Chinese risk actors, suggesting that the menace actor is repurposing existing source code to devise customized resources.
A closer evaluation of the aforementioned area has also uncovered the existence of yet another ELF artifact (i.e., Sword2033) that supports three simple features, which include uploading and exfiltrating documents and executing commands.

The malware’s backlinks to Alloy Taurus stems from the truth that the area fixed to an IP tackle that was previously discovered as an active indicator of compromise (IoC) linked with a prior campaign concentrating on firms operating in Southeast Asia, Europe, and Africa.
The concentrating on of South Africa, per the cybersecurity corporation, arrives in opposition to the backdrop of the place holding a joint 10-day naval drill with Russia and China previously this 12 months.
“Alloy Taurus continues to be an lively risk to telecommunications, finance and federal government corporations across Southeast Asia, Europe and Africa,” Unit 42 mentioned.
“The identification of a Linux variant of PingPull malware, as nicely as current use of the Sword2033 backdoor, suggests that the group proceeds to evolve their functions in help of their espionage pursuits.”
