Your business is fully protected from cyber attacks ? It is difficult to say yes after seeing the WannaCry and its impact on businesses around the world. One of the largest cyber scams in history threw the vulnerability of entrepreneurs who are thinking about defending your information only with a good antivirus.
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 .
As in other virtual attacks produced by this type of threat, criminals exploited a vulnerable computer, which in this case referred to a Microsoft Windows sharing protocol. Quickly, the virus has spread and, on the screen of infected devices, came the ransom.
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. The businessman runs against him to find a way to unlock the data without paying the ransom, but every minute sees growing risk of misuse of their information.
Why should you also worry
The practices ransomware are not uncommon. In the United States, for example, had already been registered 65% increase in the number of cases in 2015, compared to the previous year. But what surprised everyone was now the proportion of WannaCry.
Even if you only hear about cyber attacks by the media, we need to be aware that they are getting bigger , bolder and also closer.
Petrobras, for example, was affected by the blow. The same occurred in Justice of at least eleven states courts. And even federal agency such as the National Social Security Institute (INSS) and the Brazilian Institute of Geography and Statistics (IBGE), escaped this time.
Several other government agencies just disabling systems, removing air sites and even disconnecting the internet in their units. All to contain the advance of WannaCry institutions.
See for this latest example that there is no one is immune to cyber attacks. Imagine, then, how it would be to have your cash flow in the hands of bandits ? Or get blocked access to their invoices, customer records and negotiating sales ? And the worst: being blackmailed for it. Hard to calmly deal with this kind of situation, you agree?
