In the aftermath of WannaCry, security researchers are trying to help make life easier to protect against the next attack.
Along those lines, ESET created a script that can check a computer to see if Windows has already been patched for WannaCry ransomware.
The WannaCry ransomware is based on a vulnerability called EternalBlue stolen by hacking group Shadow Brokers from the NSA last year.
The same hacking group decided to publish it online earlier this year, and it was only a matter of time until cybercriminals developed exploits based on the vulnerability in order to attack systems worldwide.
Essentially, the only thing users have to do is patch their systems, as Microsoft has already released updates that can block the exploit.
The problem is, though, not everyone installs updates as soon as they’re released, and this is why so many computers fell victim to WannaCry.
Security company ESET released a bonus app called EternalBlue Vulnerability Checker, which is essentially a very simple script that can check whether your system is patched against the ransomware or not.
There’s not much you need to do after downloading the app because simply running it is enough to trigger the scanning process and determine if all patches are on your system.
Unfortunately, more advanced features are missing, so for instance, it cannot download and install the updates that can get you protected against WannaCry. On the other hand, installing the updates is not difficult at all, and doing it in Windows is easy because the options to check for and install the most recent patches are baked into the operating system.
