By now you have heard about the major ransomware attack using a leaked NSA exploit known as “WannaCry” that has hit approximately 150 countries since last Friday. About 200,000 infections globally have been detected and the attack, which uses the WannaCry (WanaCrypt0r 2.0) ransomware, continues to spread shutting down critical network infrastructure for hospitals, financial institutions, and government agencies around the world.
WannaCry utilizes the ETERNALBLUE exploit targeting newly disclosed vulnerabilities (MS17-010). Once leaked, it took only 28 days for this exploit to be used in a full-scale cyber-attack. Organizations that scan for vulnerabilities only monthly or less frequently can still be at risk.
It is unfortunate to know this cyber-attack was easily defeated by simply updating the security patches on your windows operating system. Another disturbing fact is the number of organizations still running old versions of Windows e.g. Windows XP and Vista. So what can you do to reduce the risk of these kind of cyber-attacks on your organizations computer network.
- If you are still running an old operating system them upgrade to the most current
- Make sure you turn on automatic updates on your computers.
- Make sure you restart your computers at least twice a week so updates can install
- Never Ever click on any links or graphics received in you and your employees Email
- Conduct employee cyber security awareness training for everyone in your organization
