Since Friday (May 12th), the cyber-attack has victimised private and public organisations in 150 countries and, according to Microsoft, should be treated as a wake-up call across the globe.
You should make multiple backups – to cloud services and using physical disk drives, at regular and frequent intervals.
The cyber-attack has disrupted NHS services in parts of England and Scotland since Friday afternoon.
“The problem is that there are a lot of Windows computers out there that either don’t have automatic updates enabled or are so outdated that Microsoft has stopped providing security updates altogether”, Vox said.
While Microsoft’s reputation has suffered in the past because of security problems, the company’s stock is barely down from the close of trading Thursday, just before reports of the ransomware.
The company also reiterated a call it made earlier this year for an worldwide agreement among states to shield civilians and corporate noncombatants from hacking.
According to the company, “customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March”.
Kaspersky Labs’s Global Research and Analysis team points out that WannaCry starts with a remote code execution in Microsoft Windows, taking advantage of a vulnerability dubbed “EternalBlue”. “But now what you have, in the form of nation-state malware as created by the NSA, is the ability to really dive deep and encrypt the important data in a system, and it really gets scary”.
“WannaCry” (also called “WannaCrypt) refers to ransomware that has been spreading wildly since last Friday”.
What versions of Windows are affected?
However, Bossert warned that following the patching advice from Microsoft and the Federal Bureau of Investigation should be a top priority to stop the spread of ransomware, which has hit a number of large-profile companies, including FedEx. Two former intelligence officials and a retired Navy admiral told the Senate committee on Thursday that the US lacks first responders for cyber attacks.
What simple steps can we all follow?
But there are a few things that businesses can do to limit the damage it causes. The victims have been advised not to pay the $300 ransom requested by the hackers, who’ve threatened to wipe PCs of those who don’t pay up in a given timeframe.
However, if you do pay, you’re only fueling the fire.
Every action players can take in the game is associated with cyber-security good practice, and when threats hit, visual effects provide instant feedback.
Ransomware is the name given to software used to encrypt or “lock” data files in the possession of another person for the goal of holding that data to ransom.
