Hackers Turning to ‘Unique’ Programming Languages for Malware Growth


malware programming languages

Menace actors are more and more shifting to “unique” programming languages equivalent to Go, Rust, Nim, and Dlang that may higher circumvent standard safety protections, evade evaluation, and hamper reverse engineering efforts.

“Malware authors are recognized for his or her capability to adapt and modify their abilities and behaviors to benefit from newer applied sciences,” said Eric Milam, Vice President of menace analysis at BlackBerry. “That tactic has a number of advantages from the event cycle and inherent lack of protection from protecting merchandise.”

On the one hand, languages like Rust are safer as they provide ensures like memory-safe programming, however they may also be a double-edged sword when malware engineers abuse the identical options designed to supply elevated safeguards to their benefit, thereby making malware much less prone to exploitation and thwart makes an attempt to activate a kill-switch and render them powerless.

Stack Overflow Teams

Noting that binaries written in these languages can seem extra advanced, convoluted, and tedious when disassembled, the researchers stated the pivot provides further layers of obfuscation, just by advantage of them being comparatively new, resulting in a situation the place older malware developed utilizing conventional languages like C++ and C# are being actively retooled with droppers and loaders written in unusual alternate options to evade detection by endpoint safety techniques.

Earlier this 12 months, enterprise safety agency Proofpoint found new malware written in Nim (NimzaLoader) and Rust (RustyBuer) that it stated have been being utilized in energetic campaigns to distribute and deploy Cobalt Strike and ransomware strains through social engineering campaigns. In an analogous vein, CrowdStrike final month observed a ransomware pattern that borrowed implementations from earlier HelloKitty and FiveHands variants, whereas utilizing a Golang packer to encrypt its foremost C++-based payload.

Prevent Data Breaches

Among the outstanding examples of malware written in these languages over the previous decade are as follows –

  • Dlang – DShell, Vovalex, OutCrypt, RemcosRAT
  • Go – ElectroRAT, EKANS (aka Snake), Zebrocy, WellMess, ChaChi
  • Nim – NimzaLoader, Zebrocy, DeroHE, Nim-based Cobalt Strike loaders
  • Rust – Convuster Adware, RustyBuer, TeleBots Downloader and Backdoor, NanoCore Dropper, PyOxidizer

“Packages written utilizing the identical malicious methods however in a brand new language usually are not often detected on the identical charge as these written in a extra mature language,” BlackBerry researchers concluded.

“The loaders, droppers and wrappers […] are in lots of instances merely altering the primary stage of the an infection course of somewhat than altering the core parts of the marketing campaign. That is the most recent in menace actors shifting the road simply exterior of the vary of safety software program in a method which may not set off on later phases of the unique marketing campaign.”
