Over 237,000 computers worldwide were affected by malware known as WannaCry last weekend. And although the spread of the ransomware attack slowed over, the respite might only be brief.
Wanna Decryptor, also known as WannaCry or wcry, is a specific ransomware program that locks all the data on a computer system and demands a $300 payment in Bitcoin before unlocking it. Specialized IT companies like Penta had their experts working over the weekend to make sure all preventive measures are in place to ensure that no critical business is affected.
The malware was able to spread thanks to flaws in old versions of Windows. And although Microsoft has taken a rare step of issuing patches for unsupported Windows’s versions, and a security researcher triggered the kill switch to halt the global spread of the virus, the threat is not over yet.
It is difficult to prevent determined hackers from launching a ransomware attack, but being careful helps. Cyber attackers need to download the malicious software onto a computer, phone or other connected device and the most common channels are compromised emails and websites.
According to Microsoft’s Malware Protection Center, there are certain steps you should take to protect yourself against WannaCry or any other ransomware:
If you don’t have patches from April or May download the latest update version from the Microsoft Update Catalog, and install it.
Have a clear set of security rules which are known and followed by all the employees. You can have the most secure system in the world, but hackers will always seek out the weakest link.
According to the ACC Foundation: State of Cybersecurity Report Data breaches are most likely to be the result of employee error or an inside job. Make sure your internal security policies are in place. Handling the aftermath of any crypto malware attack is a huge challenge for any organization. Prevent it before it becomes your problem.
