NSA Told Microsoft of Flaw Before Ransomware Attack

While it's not clear what could have possibly prompted organisations to under-report the impact of WannaCry ransomware, this could well be a cost saving measure, but at the expense of data security. "Ransomware is painful, but you can restore operations relatively quickly". The best course of action is to contact an IT or Cyber Security professional to assist you in analyzing and minimizing the attack. And as these devices connect to the Internet, they become vulnerable to ransomware and other computer threats. After a brief configuration period, the automated system transfers all of your important data to the cloud, where the service provider maintains and protects it separately from your own network in the event of an attack.

Abutbul told me, "The WannaCry/Wcry ransomware-the largest ransomware infection in history-is a next-gen ransomware". Who started this mess? According to news reports the virus was a hacking tool stolen from the US National Security Agency (NSA).

It said it was set to sell access to previously undisclosed vulnerabilities, known as zero-days, that could be used to attack Microsoft Corp's latest software system, Windows 10. In other words, paying may not guarantee you can again access your files. Sites like Carbonite offer you fair-priced options for keeping your data safe. On affected version of Windows, merely disabling a networking technology called SMB (an task beyond typical users' abilities) would block WannaCry, for instance. That means those customers will not have received the above mentioned Security Update released in March.

Ahead of the attack, Microsoft released a security update that fixes the exploited flaw on now supported Windows operating systems. The kill switch is basically a code used by attackers to halt the spread of their software if things get out of hand. While investigating the attack, he noticed that the malware was trying to contact a specific web address each time it infected a new computer, and that the web address it was trying to contact had not been registered.

Why are hackers asking for ransom in Bitcoin? Suppose if these hackers end up providing bank account details, now authorities would be able to track down their location with this information and put an end to their nefarious activities.

Is the WannaCry attack over?

And that specific problem is slowly going away, thanks to the rise of a mobile, cloud-connected world. Researchers have already demonstrated a ransomware attack against smart thermostats, which may sound like a nuisance at first but can cause serious property damage if it's cold enough outside.

The good news is, these attacks are preventable if you keep your software up to date and your guard up.

Microsoft, which on Friday took the unusual step of issuing a custom security update for users whose systems no longer receive regular support, has urged users with older versions of Windows to patch the vulnerability as soon as possible.

Part of why the attack was carried out successfully was because millions of computers continued to run Windows XP. If an email appears to have come from your bank, credit card company or internet service provider, keep in mind that they will never ask for sensitive information like your password or social security number.

What to do if my PC is infected by WannaCry? But he added that with WannaCry, people definitely should not pay the ransom. If we were to replicate our world according to the blockchain principles, our private data would be spread over the world in a decentralized manner, and at the same time encrypted. "Take periodic backups on to external Hard Disk Drives".

The countries most affected seem to be Russia, Ukraine, India, China, Italy and Egypt, with Russia having over 1,000 computers affected by the ransomware.
