Singapore malls, users hit in cyber attack- Secure yourself from ransomware!

 

On 12th May 2017, there was a global wide-spread infections of a ransomware known as "WannaCry" aka. WanaCrypt0r. This ransomware has the capability to spread over the network by scanning for vulnerable systems, and infecting them. It then encrypts files on the system, and exhorts a ransom payment in bitcoin for the decryption of files. Since the initial news of the infections, Singapore has seen a number of victims struck by the ransomware.

Why is “Wannacry” dangerous


What makes Wannacry dangerous is that the attackers are leveraging a Windows exploit developed by NSA called EternalBlue, and reportedly leaked and dumped by the Shadow Brokers hacking group over a month ago. Since then, it has spread rapidly across the world affecting thousands of systems in over 100 countries. The exploit has the capability to penetrate into machines running unpatched version of Windows through 2008 R2 by exploiting flaws in Microsoft Windows SMB Server. Once a single computer in your organization is hit by the WannaCry ransomware, the worm looks for other vulnerable computers within it your network and infects them as well.

Recommendations


Prevention is always better than seeking for a cure.  For the “Wannacry” ransomware, this principle is strongly recommended. For this Ransomware, Microsoft has released a patch for the vulnerability in March (MS17-010).  Do this now if you have not done so. Like all other ransomware infection, you should always be suspicious of uninvited documents send through email. Do  not click on links inside these documents unless you have verified the source. Always make backup of your important files and documents, this will save you when you have to restore your files and documents when needed. Do ensure that you run an active anti-virus security suite of tools on your system, and most importantly, always browse the Internet safely.
