cc5b A never-before-seen Linux malware has cc5b been dubbed a “Swiss Military cc5b Knife” for its modular structure cc5b and its functionality to put cc5b in rootkits.
cc5b
cc5b This beforehand undetected Linux menace, cc5b known as cc5b Lightning Framework cc5b by Intezer, is provided cc5b with a plethora of options, cc5b making it probably the most cc5b intricate frameworks developed for concentrating cc5b on Linux programs.

cc5b “The framework has each passive cc5b and energetic capabilities for communication cc5b with the menace actor, together cc5b with opening up SSH on cc5b an contaminated machine, and a cc5b polymorphic malleable command and management cc5b configuration,” Intezer researcher Ryan Robinson cc5b cc5b mentioned cc5b in a brand new cc5b report revealed at this time.

cc5b Central to the malware is cc5b a downloader (“kbioset”) and a cc5b core (“kkdmflush”) module, the previous cc5b of which is engineered to cc5b retrieve at the least seven cc5b totally different plugins from a cc5b distant server which are subsequently cc5b invoked by the core element.

cc5b As well as, the downloader cc5b can be chargeable for establishing cc5b the persistence of the framework’s cc5b primary module. “The primary perform cc5b of the downloader module is cc5b to fetch the opposite elements cc5b and execute the core module,” cc5b Robinson famous.

cc5b The core module, for its cc5b half, establishes contact with the cc5b command-and-control (C2) server to fetch cc5b mandatory instructions required to execute cc5b the plugins, whereas additionally taking cc5b care to cover its personal cc5b presence within the compromised machine.
cc5b
cc5b A number of the notable cc5b instructions obtained from the server cc5b allow the malware to fingerprint cc5b the machine, run shell instructions, cc5b add recordsdata to the C2 cc5b server, write arbitrary knowledge to cc5b file, and even replace and cc5b take away itself from the cc5b contaminated host.
cc5b
cc5b It additional units up persistence cc5b by creating an cc5b initialization script cc5b that is executed upon cc5b system boot, successfully permitting the cc5b downloader to be robotically launched.

cc5b “The Lightning Framework is an cc5b fascinating malware as it isn’t cc5b widespread to see such a cc5b big framework developed for concentrating cc5b on Linux,” Robinson identified.

cc5b The invention of Lightning Framework cc5b makes it the fifth Linux cc5b malware pressure to be unearthed cc5b in a brief interval of cc5b three months after cc5b BPFDoor cc5b , cc5b Symbiote cc5b , cc5b Syslogk cc5b , and cc5b OrBit cc5b .
