“The estimated 200,000 computers crippled worldwide by last week’s mammoth ransomware attack could be only the tip of the iceberg, security experts said Sunday.”

So what is WannaCry? – 

The malware spreads as a worm — scanning other computers linked to any machine or system it infects for the same defect and leaping onto them — through a vulnerability in Microsoft systems, particularly on outdated software like Windows XP or Windows Server 2003.

The malware includes an encryption package that automatically downloads itself to infected computers, locking up nearly all of the machines’ files and demanding payment of $300 to $600 for a key to unlock them.

What can you do?

Currently, there is no WannaCry decryption tool or any other solution available, so users are strongly advised to follow prevention measures in order to protect themselves. This also applies on a day-to-day basis.

Keep your system Up-to-date: First of all, if you are using supported, but older versions of Windows operating system, keep your system up to date, or simply upgrade your system to Windows 10.

Using Unsupported Windows OS? If you are using unsupported versions of Windows, including Windows XP, Vista, Server 2003 or 2008, apply the emergency patch released by Microsoft today.

Be Vigilant: Always make sure that any email attachment is legitimate – if you are not expecting one – check with the sender. NEVER follow any unsolicited links in an email or attachment. If in doubt – ASK!.

Keep your Antivirus software up-to-date: Virus definitions have already been updated to protect against this latest threat.

Backup Regularly: To always have a tight grip on all your important files and documents, keep a good backup routine in place that makes their copies to an external storage device that is not always connected to your PC. Offsite backups are ideal.

Beware of Phishing: Always be suspicious of uninvited documents sent an email and never click on links inside those documents unless verifying the source.
