What You Need to Know about WannaCry Ransomware


Print Friendly, PDF & Email

A worldwide ransomware attack known as “WannaCry” has affected over 200,000 victims in 150 countries. WannaCry targeted a flaw in Microsoft’s Windows operating system. Back on March 14, Microsoft issued a patch for the vulnerability, but many computers hadn’t run the update. Many of the computers impacted run older Windows systems like XP. This caused Microsoft to issue a rare patch for XP, which is no longer supported.

How does Ransomware work?

Hackers use ransomware attacks to lock down computers and threaten to delete all data unless a ransom is paid.

What can you do to keep your data safe?

It’s simple. Patch your computers with the latest software updates. Proper patching lowers the risk of falling victim to attacks.

Ransomware is on track to be an $1 billion crime in 2017, according to FBI data. To keep your data as secure as possible be sure that you are doing the following:

  • Back up data regularly
  • Secure your offline backups
  • Configure firewalls
  • Logically separate networks
  • Patch operating systems, software, and firmware on devices
  • Implement an awareness and training program
  • Scan all incoming and outgoing emails
  • Enable strong spam filters to prevent phishing emails
  • Block ads
  • Use the principle of “least privilege” to manage accounts
  • Leverage next-generation antivirus (NGAV)
  • Use application whitelisting
  • Categorize data based on organizational value
  • Conduct an annual penetration test
