15 May All You Need To Know About WannaCry Ransomware Outbreak
Over the weekend, a massive global Ransomware attack became quite public news, hitting many large organisations. One of the most concerning was the British National Health Service (NHS) which crippled the ability to provide care to patients.
The target of the attacks was a vulnerability in the Microsoft Windows operating system that that was exploited. The vulnerability was patched during a March release of updates from Microsoft on each of affected systems, which also included the end of life Windows XP and Windows 2003 which ended support on April 8, 2014.
The specific variant that was released over the weekend has actually been stopped, you can read a detailed account of how in the article written by MalwareTech here:
However, there have been new releases since and there will continue to be new variants released so it is important to understand the key measures you can use to protect your data:
- Ensure your systems are up to date with patches – this includes Windows, Mac, Office, Java, Flash – any application. Most updates released by vendors are security patches and bug fixes
- Install a business grade, robust anti-malware solution from a vendor such as Sophos or WebRoot
- Make sure your backups are good. They must go offsite or be disconnected from the network to prevent the files from being encrypted in the event of an attack
- Don’t click on any emails that you are unsure of! If its unsolicited or doesn’t look right – it probably isn’t
