Following yesterday’s unprecedented (as in global) ransomware attack that wreaked havoc among tens of thousands of computers networks all around the world, Microsoft took a rather unusual step for securing its older OS versions by releasing an emergency patch for the unsupported Windows XP, Vista, Server 2003 and 2008 and Windows 8.
If your company/organization is currently running any of the OS’s mentioned above, you should apply the patch as soon as possible. Over 114,000 computers were compromised in the last 24 hours alone by the WannaCry Ransomware and according to cyber-security experts, we should expect a new wave of ransomware attacks soon, as the 2.0 version of the respective malware just arrived in the shops so to speak, and this time there’s no kill switch function, as it was the case with the first variant.
It’s worth noticing that if you’re running Windows 10, you’re on the safe side, as the exploit code used in this ransomware attack is designed to compromise unpatched Win 7/ Win Server or earlier systems only.
The scale of yesterday’s attack was so humongous that Microsoft did the unthinkable, i.e. they released a software patch even for the ancient Windows XP, 3 years after the company discontinued its support for the respective operating system.
WannaCry is currently under investigation so to speak, as European Cybercrime Centre and Europol are trying to determine who’s behind this unprecedented attack.
