M?lof?e: Researchers Uncover New Linux Malware Linked to Chinese APT Groups

An unknown Chinese state-sponsored hacking group has been linked to a novel piece of malware aimed at Linux servers.

French cybersecurity firm ExaTrack, which found three samples of the previously documented malicious software that date back to early 2022, dubbed it M?lof?e.

One of the artifacts is designed to drop a kernel-mode rootkit that’s based on an open source project referred to as Reptile.

“According to the vermagic metadata, it is compiled for a kernel version 5.10.112-108.499.amzn2.x86_64,” the company said in a report. “The rootkit has a limited set of features, mainly installing a hook designed for hiding itself.”

Both the implant and the rootkit are said to be deployed using shell commands that download an installer and a custom binary package from a remote server.

The installer takes the binary package as an argument and then extracts the rootkit as well as a server implant module that’s currently under active development.

M?lof?e’s features are no different from other backdoors of its kind, enabling it to contact a remote server and receive instructions that allow it to carry out file operations, create sockets, launch a shell, and execute arbitrary commands.

The malware’s ties to China come from infrastructure overlaps with groups such as APT41 (aka Winnti) and Earth Berberoka (aka GamblingPuppet).

Earth Berberoka is the name given to a state-sponsored actor chiefly targeting gambling websites in China since at least 2020 using multi-platform malware like HelloBot and Pupy RAT.

According to Trend Micro, some samples of the Python-based Pupy RAT have been concealed using the Reptile rootkit.

Also discovered by ExaTrack is another implant codenamed AlienReverse, which shares code similarities with M?lof?e and makes use of publicly-available tools like EarthWorm and socks_proxy.

“The M?lof?e implant family is another tool in the arsenal of Chinese state sponsored attackers, which show constant innovation and development,” the company said.

“The capabilities offered by M?lof?e are relatively simple, but may enable adversaries to conduct their attacks under the radar. These implants were not widely seen, showing that the attackers are likely limiting its usage to high value targets.”
