WannaCry Ransomeware Virus - are you at risk?
Am I at risk?
The WannaCry ransomware affects machines running the Windows operating system. It was a security flaw that was originally exploited by the U.S. National Security Agency (NSA) which was then leaked earlier this year. Hackers are now using this themselves.
If you or your organization is running a version of Windows, you could be at risk.
How can my data be better protected?
If you are a home user, make an offline backup of your files and keep them somewhere safe. If they are offline, they won't be at risk. Assume that anything on your network, NAS drives and such - will be at risk for sure. We have seen how dangerous ransomeware can be, and once it encrypts your files at 256-bit encryption, it's all over. Paying the ransom via bitcoin is not a wise option!
Update your Windows to the latest patches, and ensure your antivirus is updated also. If you regularly
download obtain files like music and videos from torrent sites, you will be completely at risk, since most of these sites are highly dubious at best.
Individuals and small businesses should:
Run Windows Update to get the latest software updates.
Make sure any anti-virus product is up to date and scan your computer for any malicious programs. It's also worth setting up regular auto-scans.
Back up important data on your computer in case it gets held for ransom.
Large organizations should:
- Apply the latest Microsoft security patches for this particular flaw.
- Back up key data.
- Ensure all outgoing and incoming emails are scanned for malicious attachments.
- Ensure anti-virus programs are up to date and conducting regular scans.
- Educate employees on identifying scams, malicious links and emails that may contain viruses.
- Make sure to run "penetration tests" against your network's security, no less than once a year,
