Right here’s a SophosLabs technical paper that ought to tick all of your jargon containers!

Our specialists have deconstructed a pressure of malware known as Glupteba that makes use of nearly each cybercrime trick you’ve heard of, and possibly a number of extra apart from.

Like plenty of malware today. Glupteba is what’s recognized a zombie or bot (brief for software program robotic) that may be managed from afar by the crooks who wrote it.

But it surely’s greater than only a distant management software for criminals, as a result of Glupteba additionally features a vary of parts that permit it function all the following:

  • A rootkit. Glupteba consists of quite a lot of Home windows kernel drivers that may conceal the existence of particular information and processes. Kernel rootkits are uncommon today as a result of they’re complicated to put in writing and infrequently draw pointless consideration to themselves. Nonetheless, if loaded efficiently, rootkits might help cybersecurity threats lie low by maintaining malware information off the radar of safety instruments and stopping them from exhibiting up in safety logs.
  • A safety suppresor. Glupteba has a module that does its greatest to show Home windows Defender off, after which often checks to verify it hasn’t turned itself again on. It additionally appears for a laundry checklist of different safety instruments, together with anti-virus software program and system monitoring applications, killing them off to allow them to now not seek for and report anomalies.
  • A virus. Glupteba makes use of two completely different variants of the ETERNALBLUE exploit to distribute itself routinely throughout your individual community, and anybody else’s it may discover by reaching out out of your pc. That makes it an old-school, self-spreading pc virus (or extra particularly a worm) slightly than only a standalone piece of malware.
  • A router assault software. Glupteba bundles in numerous exploits towards fashionable house and small enterprise routers, utilizing your pc as a leaping off level to assault different individuals. It makes use of one in all these assaults to open up unpatched routers to behave as community proxies that the crooks can use as “jumping off” factors for future assaults. This leaves the unlucky sufferer wanting like an attacker themselves and exhibiting up as an obvious supply of cybercriminal exercise.
  • A browser stealer. Glupteba goes after native knowledge information from 4 completely different browsers – Chrome, Firefox, Yandex and Opera – and uploads them to the crooks. Browser information typically comprise delicate info akin to URL historical past, authentication cookies, login particulars and even passwords that may’t be accessed by code akin to JavaScript operating contained in the browser. So crooks like to assault your browser from exterior, the place the browser isn’t in management.
  • A cryptojacker. Together with every thing else it does, Glupteba can act as a secretive administration software for 2 completely different cryptomining instruments. Cryptominers are authorized in case you use them with the specific permission of the particular person paying the electrical energy payments to run the computer systems you’re utilizing (and cryptomining can devour plenty of energy). Right here, the crooks get you to pay their energy payments and take the cryptocoins for themselves.
