Cybersecurity Today

Network (internets) are not secure enough due to the lack of efficient cybersecurity. As a result, ransomware attacks are increasing affecting most businesses and individuals today. Enacting measures to detect cyberattacks and ransomware attacks can be helpful in preventing unforeseen repercussions from the attacker in the corporate network. Cybersecurity needs to implement new policies and recommendations so that the ransomware attack can reduce. This report will first discuss some ransomware attack that as happened before; next the report will discuss who is affected by the ransomware attacks and finally, the report will discuss how the ransomware attack can be reduced.

Earlier this year, Microsoft was affected by what has been called the “biggest ransomware outbreak in history”. By exploiting a bug in unpatched Microsoft operating systems, this global cyberattack infected more than 300,000 computers in 150 countries. Hackers spread ransomware known as WannaCry by using phishing techniques through email. Users would receive emails that would trick them into opening attachments that released malware into their systems. Once their computers had been affected, the ransomware would literally take their files for random, locking them up and encrypting them, then demanding payment of bitcoins to regain access to their files. Although users were told they would regain access to their files following payment, many users did not regain access to their files and while continuously being told to pay more and more for the “ransom”.

In order for this attack to be stopped or reduced the cybersecurity needs to implement new policies and recommendations. One of the policy is authentication techniques this is an important policy that is commonly employed in the most corporate network to protect against similar attack to ransomware attacks. This provides for the use of two-way authentication, key management and automated management of key. The techniques offer the ability to encrypt and decrypt without the use of a centralized file protection or critical management system. Although this policy has been employed in the company to protect against attacks, more research is being carried out to reinforce the mentioned techniques.

Another policy that need to be implemented is patch or software update Apparently, ransomware creators mostly rely on users running on outdated software with known vulnerabilities, which are easily exploited to penetrate into the corporate network. Installing updates help manage and fix vulnerabilities which are quickly exploited to install ransomware. In fact, research shows that leaving just a single computer in an environ where the most recent patch is not installed can threaten the stability of the whole environment and perhaps impede standard functionality. Possibly the biggest lesson that consumers learned from this cyberattack was that regularly updated their systems was essential in order to protect their equipment, and to be vigilant and alert when it comes to suspicious emails and notifications from both familiar and unfamiliar senders.
