A large-scale electronic attack has disrupted tens of thousands of computers around the world on Friday, in what experts say is an unprecedented electronic attack.
The following are some of the questions and answers related to this attack:
what happened?
Malicious software has infiltrated tens of thousands of computers in homes, companies and government agencies, causing encryption and blocking access to content until users pay $ 300 to $ 600 in virtual currency. Some 100 States have been attacked.
What explains the extent of that attack?
Hackers have taken advantage of vulnerabilities in the world's most widely used operating system, Microsoft Windows. The computer software giant released a patchwork solution in March to fix a security flaw, but computers that did not run the update were vulnerable to the attack.
The UK National Health Authority (NHA), which has been using the Windows XP operating system for 15 years, has been one of the most prominent organizations.
It is worth mentioning that the operating system "XP" is very old and Microsoft is no longer issuing free software to update it. The company said on Saturday it was reviewing the policy.
How do malicious and harmful programs enter your computer?
The electronic weapon used in that attack is one of the hidden and harmful electronic programs called "Wana Decryptor" or "Wanakrai". The program infiltrates the computer through electronic links and attachments in spam emails.
According to e-security experts, unknown hackers have benefited from stolen tools from the US National Security Agency. Parts of the agency's "cyber arsenal" or electronic / complex arsenal have been leaked online in recent months.
