Newly found Lightning Framework offers a plethora of Linux hacking capabilities

by WDC News 6 Staff


The software program framework has turn into important to growing nearly all advanced software program lately. The Django Internet framework, as an example, bundles all of the libraries, picture recordsdata, and different elements wanted to rapidly construct and deploy internet apps, making it a mainstay at corporations like Google, Spotify, and Pinterest. Frameworks present a platform that performs frequent features like logging and authentication shared throughout an app ecosystem.

Final week, researchers from safety agency Intezer revealed the Lightning Framework, a modular malware framework for Linux that has gone undocumented till now. Lightning Framework is post-exploit malware, that means it will get put in after an attacker has already gained entry to a focused machine. As soon as put in, it may well present among the identical efficiencies and velocity to Linux compromises that Django supplies for internet growth.

“It’s uncommon to see such an intricate framework developed for focusing on Linux methods,” Ryan Robinson, a safety researcher at Intezer, wrote in a put up. “Lightning is a modular framework we found that has a plethora of capabilities, and the flexibility to put in a number of forms of rootkit, in addition to the aptitude to run plugins.”

Lightning consists of a downloader named Lightning.Downloader and a core module named Lightning.Core. They hook up with a chosen command and management server to obtain software program and obtain instructions, respectively. Customers can then run any of no less than seven modules that do every kind of different nefarious issues. Capabilities embody each passive and energetic communications with the menace actor, together with opening a safe shell on the contaminated machine and a polymorphic malleable command.

The framework has each passive and energetic capabilities for communication with the menace actor, together with opening up SSH on an contaminated machine, and assist for connecting to command and management servers that use malleable profiles. Malware frameworks have existed for years, however there aren’t many who present a lot complete assist for the hacking of Linux machines.

In an e-mail, Robinson mentioned Intezer discovered the malware on VirusTotal. He wrote:

The entity that submitted it seems to be associated to a Chinese language manufacturing organisation that makes small motor home equipment. We discovered this based mostly on different submissions from the identical submitter. I fingerprinted the server that we used to determine the corporate they usually have been certainly utilizing Centos (which the malware was compiled for). However this nonetheless shouldn’t be stable sufficient to conclude that they have been the targets or contaminated with the malware. We have now not realized something new for the reason that publication. The perfect factor which we hope to seek out is among the encrypted malleable C2 configuration profiles. It will give us community IOCs to carry out pivoting off.

Intezer was in a position to acquire components of the framework however not the whole lot. From the recordsdata the corporate researchers have been in a position to analyze, they may infer the presence of different modules. The corporate supplied the next overview:

Identify Identify on Disk Description
Lightning.Downloader kbioset The persistent module that downloads the core module and its plugins
Lightning.Core kkdmflush The principle module of the Lightning Framework
Linux.Plugin.Lightning.SsHijacker soss There’s a reference to this module however no pattern discovered within the wild but.
Linux.Plugin.Lightning.Sshd sshod OpenSSH with hardcoded non-public and host keys
Linux.Plugin.Lightning.Nethogs nethoogs There’s a reference to this module however no pattern discovered within the wild but. Presumably the software program Nethogs
Linux.Plugin.Lightning.iftop iftoop There’s a reference to this module however no pattern discovered within the wild but. Presumably the software program iftop
Linux.Plugin.Lightning.iptraf iptraof There’s a reference to this module however no pattern discovered within the wild but. Presumably the software program IPTraf
Linux.Plugin.RootkieHide libsystemd.so.2 There’s a reference to this module however no pattern discovered within the wild but. LD_PRELOAD Rootkit
Linux.Plugin.Kernel elastisearch.ko There’s a reference to this module however no pattern discovered within the wild but. LKM Rootkit

Up to now there aren’t any identified cases of the Lightning Framework being actively used within the wild. Then once more, given the abundance of obtainable capabilities, state-of-the-art stealth is undoubtedly a part of the package deal.
