How Much Damages Made By Wannacry Ransomware Attack Made Throughout The World

19 May 2017, 11:22 | Megan Pierce

WannaCry seems to have attacked computers in Russian Federation first, after which the ransomware quickly spread to as much as 150 + countries and affected Microsoft computers. The attacks highlight the challenges that organizations face with consistently applying security safeguards on a large scale. Because the file arrives in an encrypted format, many security systems are not able to immediately detect the problem, allowing the ransomware to quickly spread across any connected drives or networks. "Cautious online behavior would probably have prevented the malware from infecting the network in the first place". This ransomware was different in that it spread of its own accord through unpatched systems (systems that had not followed recent warnings to protect against a virus and back-up their files) - as a worm. Here are some tips from security experts. Malicious software called WannaCry infected more than 200,000 computers worldwide, locking out users unless they paid a ransom in bitcoins to the attackers.

In Great Britain, as the ransomware infections cascaded through scores of hospitals, doctors' offices, and ambulance companies on Friday, patients were diverted away from emergency rooms, caretakers were left without access to important information, and the government was forced to declare a "major incident", cautioning residents that local health services could become overwhelmed.

The latest brazen ransomware attacks are a sign of more to come.

Both Murakami Wood and Munro painted a picture of a future where a huge number of devices are running out-of-date, unsupported software that will never receive security patches. Getting people to understand how is still a serious challenge.

WannaCry exploits a weakness within the older versions of Windows 7 and XP. There are jokes flooding messaging apps related to Ransomware. Also, download anti-virus apps only from reputable vendors like Kaspersky Lab, Bitdefender or Malwarebytes, Mr Kamden said. "However, it should be noted that the Adylkuzz campaign significantly predates the WannaCry attack, beginning at least on May 2 and possibly as early as April 24". Users are warned to be careful when opening attachments or clicking links from dubious emails.

How do you spot a fishy email? Also, look for obvious typos and grammatical errors in the body. "It's not like you see Monero miners all over the world". Let's hope that now, after the severe consequences of the attack, employers will put the necessary efforts in advancing employees' knowledge about cyber security. Do not click on anything through these pop-ups, then safely close the windows.

And when you're considering a new digital device, whether that's a phone, a computer or a smart-home gadget, it's worth looking into just how long the manufacturer promises to support it with software updates (if it makes any promises at all).

For larger businesses with hundreds or thousands of employees, applying security updates organizationwide can be hard. That hole has been patched in newer versions of Windows, though not all companies and individuals have installed the patches.

Keep all employees informed of their roles in abiding by your organization's best practices. But there are a few things that businesses can do to limit the damage it causes.

Then who is, you may ask? If you have a backup, there's no need to pay ransom for your data. But he added that with WannaCry, people definitely should not pay the ransom.
