WannaCry Ransomware: What You Need to Know
Recently, England’s healthcare system was the victim of a massive cyber attack. The ransomware known as WannaCry locked doctors and employees across at least 25 hospitals out of their networks. Later, it was discovered that the same attack hit multiple organizations across the world. Find out what happened and how it become the largest ransomware attack to date.
What Did WannaCry Demand?
A hacker group known as The Shadow Brokers stole and leaked several Windows’ exploits from the NSA. Within the information leak, a remote code execution vulnerability called ExternalBlue was used to access unsecured computers and install the now infamous ransomware. The computers affected were either not updated or running Windows XP or 2000, which are operating systems that are no longer supported.
The ransomware program is modified version of WannaCrypt, a virus that has plagued computers before. The malicious software locks users from their computers, and then ask them to pay a 0 fee via bitcoin to obtain the encryption key. The longer the user takes to pay the ransom, the higher the fee becomes.
How Did the Virus Make It Onto Computers?
Like many other pieces of malware, WannaCry spread because people didn’t take proper precaution. The virus is believed to have originated from compressed files attached to emails. It’s important to avoid becoming an online victim. This is a topic that we have discussed before because there are a lot of opportunistic groups looking to take advantage of internet users.
Why Are Small and Large Businesses Using Vulnerable Systems?
Upgrading to the newest operating system is not so simple for business. For example, the UK’s National Health Service (NHS) notes that medical equipment uses old operating systems and are not easy to update. Business with multiple computers or larger IT system can also have a hard time updating their infrastructure. Some updates can break key application needed to do work. Companies have to be very careful when performing a companywide update, otherwise, it can critically damage everyone.
While Microsoft has ended support for older operating systems, they recently created a patch to address the incident. Companies using Windows XP, Windows 8, and Windows Server 2003 can now download a patch to protect their computers. If you can, we suggest updating your operating system regularly to avoid risk to your private information.
