Slingshot malware attacking router-connected devices since 2012 without detection 

In a digital age where most of our life revolves around internet connectivity, ensuring the security of our devices is paramount. Yet, amidst the plethora of malware threats lurking in the cyber world, one has managed to remain discreetly aggressive. Known as Slingshot, this malware has been attacking router-connected devices since 2012 without detection. And what’s more alarming? It’s been doing so right under our noses.

The Stealthy Operations of Slingshot

Recently, a team of vigilant researchers from Kaspersky Lab made a startling discovery. They exposed a malicious loader named Slingshot, which, unbeknownst to many, has been rigorously targeting users through routers for the past six years. One could say that this cyber threat was hiding in plain sight, and it took the acute observation of these researchers to bring its activities to light.

So, how did Slingshot manage to operate so covertly? The answer lies in its ingenious infection method.

Routers, by nature, download and operate numerous DLL (dynamic link library) files from devices. Malicious actors, exploiting this routine operation, cunningly inserted a malevolent DLL amidst a package of legitimate DLLs. This rogue DLL then interacts with connected devices, specifically targeting their memory.
