WannaCry and other cyber attacks

An unprecedented cyberattack. Thus was set the WannaCry by Europol, the European Police Office. On May 12, around the world, more than 300,000 devices have been infected by a type of ransomware , a rescue virus about which we have already warned here on the blog .

Bringing together the features of a malware (malicious software) and ransomware (rescue virus), the WannaCry kidnapped information relevant companies worldwide, including Brazil, appropriating them, blocking their access by the true owners and demanding payment for the release .

This time, the first of cybercriminals requested was $ 300 per machine, doubling the value if there is no response within two hours. As is common in this type of attack, the payment was required in bitcoin virtual currency , untraceable, which allowed the authors to remain anonymous.

What makes this kind of as dangerous scam is not just the blocking of relevant information, but the overall uncertainty as to release them after payment. After all, there is no guarantee that this will occur.

All this only adds drama to the  lack of a quick solution . Since there is no antidote that applies to all cases of ransomware , time becomes an enemy.
