The world was hit by a cyber fire sale today, right out of the movie Die Hard 4.0. In the last 24 hours, thousands of computers across hundreds of countries have been taken offline due to a ransomware attack. Antivirus provider Avast reported that at least 70,000 computers had been infected by the crippling malware program “WanaCrypt0r 2.0”.

The term “fire-sale” is from the Hollywood movie, Live Free or Die Hard. In the movie, the “Struxnet Worm” was used to cause a full-scale meltdown of all government and private industry technology. Today’s attack targeted a dozen hospitals in England and major companies, including FedEx and Spain’s largest telecom, were targeted.

At least 16 health service hospitals and organizations were affected in England. The British government cyber security arm was working with the NHS and confirmed no patient data had been compromised. Ben Rapp, CEO of IT Networks, a Solar Winds company, stated: “there’s been a lot of ransomware in hospitals, but to see 16 hospitals last time I checked and reports of other people, this problem is the biggest ransom attack we’ve seen yet.”

Ransomware is a form of software Malware. Ransomware takes control of a PC and can encrypt files or lock the computer completely. A message stating how to pay the ransom is normally displayed. Hackers request payment via an anonymous service like Bitcoin payment gateways. The malware is typically spread via email phishing schemes. An email will arrive in your inbox requesting you to open a file. The email may state something like, invoice or tracking number, please open. Once the email or file is opened, the virus begins to slowly lock filesystems and encrypt hard drives.

Hackers typically target home networks or small businesses with Ransomware. The scale of this attack has sent a shockwave through IT security communities. I have personally worked in the IT space over 25 years. I’ve never heard of a Ransomware attack of this magnitude. Details are coming out that the ransomware is primarily affecting Windows-based PCs. This malware is particularly nasty because it is finding holes in networks utilizing window sharing technology.
