Analysis of #Koske #miner.

It is an AI-generated #Linux #malware which was hidden in images with pandas. It supports wide variety of coinminers for various cryptocurrencies and for GPU and different CPU architectures. Its another component, #rootkit #hideproc, tries to hide the Koske miner from file listings and processes.

Supershell Malware Being Distributed to Linux SSH Servers

A Chinese-developed Go-based backdoor called Supershell is targeting poorly managed Linux SSH servers. The malware, which supports multiple platforms, primarily functions as a reverse shell for remote system control. Attackers use dictionary attacks from various IP addresses to gain access, then install Supershell directly or via a downloader script. The malware is downloaded from web and FTP servers. While Supershell is the initial payload for control hijacking, XMRig Monero CoinMiners are often installed alongside it, suggesting cryptocurrency mining as the ultimate goal. To protect against such attacks, administrators should use strong passwords, update systems regularly, and implement security measures like firewalls.

Report from #AhnLab indicates a new cryptocurrency miner is attacking Linux servers https://www.linux-magazine.com/Online/News/Linux-Machines-with-Poorly-Secured-SSH-Servers-are-Under-Attack #Linux #security #crypto #SSH #server #malware #DDOSbot #CoinMiner #ASEC

#Typosquat alert: Someone set up a #fake site that mimics Sophos branding on Sopbos[.]com and that site delivers a #malware #coinminer installer called SophosInstaller.exe

If you work on a team with a #domain #reputation service or feature, please mark that domain as #malicious.

Let's all work to render this kind of garbage, and their domain registration, utterly useless. #FAFO

Some of the final payloads overlap with previously-reported threats, such as #Truebot (#downloader, often linked to Cl0p #ransomware), #Buhti (ransomware), #MoneroOcean (a #coinminer, discussed here: https://news.sophos.com/en-us/2021/12/02/two-flavors-of-tor2mine-miner-dig-deep-into-networks-with-powershell-vbscript/), and #Mirai (a #botnet #worm).

One such example of a #miner, shown in the screenshot below, details the commands to terminate the processes and services used by other, competing malicious miners before launching their own #Monero (#XMR) mining software. This cynical form of 'capture the flag' is commonplace behavior among the threat actor groups who deploy and maintain hostile miners.

5/6

I've come across this interesting article by AhnLab about how SHC is being used to deploy malicious payloads on GNU/Linux systems: "Shc Linux Malware Installing CoinMiner".

A nice reason to spend some time on this as follows in this thread.
