Producers or consumers? Who will take responsibility for security?
A ransomware epidemic called WannaCry, which has recently caused systems infections in dozens of countries and has also affected public services, hindering in many cases the functioning of society, is based on a vulnerability in the Windows Server Message Block (SMB) protocol, MS17-010. Microsoft released a revised update in March that allowed WannaCry to spread less.
According to experts from F-Secure, most companies fall victim to cyber attacks due to non-updated software that contains previously identified security flaws. The second most common reason is the use by cybercriminals of social engineering such as phishing, that is, sending faked messages to employees and impersonating a person or an institution in order to obtain certain information.
One of the last experiments carried out by F-Secure showed that the link contained in a fake e-mail pretending message from LinkedIn has been clicked by as many as 52% of employees.
- A new vulnerability is identified every 90 minutes, and several thousand vulnerabilities are disclosed each year .
- The elimination of the new vulnerability takes an average of 103 days .
- The time when new vulnerabilities are being exploited by cybercriminals has shortened from 45 to 15 days in the last decade.
Hardware and software manufacturers can not provide 100% security. Patching gaps by updating software and systems before someone tries to use them remains the best way to combat cyber attacks.
