The original attack involved replacing the C:\Windows\System32\sethc.exe binary, or one of the other accessibility suite binaries, with something that could access the underlying OS, like cmd.exe. When the executables are switched, you can bypass the login and get a system level command prompt by pushing the associated "sticky key" - e.g., Shift-key five times in a row quickly if sethc.exe is replaced. Sethc.exe and the other accessibility binaries are executed pre-login, so the attacker would have an immediate backdoor to the system without requiring authentication.

Another variant of the attack works by setting cmd.exe, or another program, as a debugger to one of the accessibility suite binaries. This requires one addition to the registry and the attacker doesn’t need to worry about the file replacement described previously.

What is Trojan.multi.accesstr.a.sh trojan

IT-specialists declare that Trojan viruses make up the biggest percentage of all malicious software, according to usability and effectiveness. These goals often have semi-legal or illegal properties, such as the steal of passwords and important information, downloading and controlling already installed adware, botnets development or espionage. Despite the numerous strengths, Trojans have one important disadvantage - they cannot penetrate user's PC independently. Recent time, users began to think that any dangerous or advertising software are viruses, but strictly speaking, you can't call Trojans viruses, since virus can replicate itself, that can avalanche spreading through local networks and the Internet. Trojans cannot reproduce themselves, and cannot penetrate the computer without victim's help. There's only thing that Trojan can do before infecting the PC is waiting until some trustful victim chooses to download it and installs it. All the facts described above lead us to one solution: Trojans should be detected and avoided until they infect the PC!

Many users think that to neutralize virus infection they just need to buy an antivirus, but that's wrong. No AV utility can help you if you download new dangerous programs every day. To make sure that the system is secure, you have to reconsider your habits, and act prudently on all websites. There are two ways to achieve this effect:

  • The safest choice is to fully quit using programs of dubious background. These principles concern all the tools downloaded not from the reliable developer websites or trusted distributors. Obviously, all cracked replicas of useful tools must also be considered potentially harmful. If you stop downloading such utilities, the probability of infection would be lowered to minimal, and antivirus can quickly deal with it.
  • If you are not ready to fully forget about using unlicensed programs, you have to carefully examine each downloaded program. Trojan viruses usually lurk beneath the guise of nice programs such as driver updaters, browsers, browser games, search engines, antiviral tools and system optimizers. Don't install weird programs from this list, and while another unlicensed utility is installing - watch closely at the installation, declining all offers for getting extra programs.

Use these advices and you will immediately feel the fruits: your system will be quick, workable and safe, and will remain so forever.
