How to protect your PC completely

In May, 2017, the global community was thrown into shock mode when news filtered in that a team of hackers called the Lazarus group from the secretive Democratic People’s Republic of Korea had released a Cyberattack codenamed WannaCry Ransomware.

Before anything could tangible could be done, over 200,000 people in as many as 150 countries of the world had already been hit by the WannaCry computer Ransomware. According to the United States’ National Security Agency (NSA), the ultimate aim of the cyberattack was to extort money for the Kim Jong Un’s cash strapped regime. The cyberattack hadn’t yelded the kind of money the perpetrators had hoped for as all they could lay their hands on was only $140,000 stored in bitcoins, a very paltry figure when compared with last years’ virtual bank heist that occurred in Bangladesh, the attackers also believed to be from North korea had smiled to their dungeon with a humongous figure of $80 million.

The combination of wannaCry worm virus with Ransomware: a first of its kind shows the growing sophistication of the hackers. Its way of operation is to obfuscate the victims’ computer data through encryption before proceding to demand for “ransome” (their own fixed amount of money) before you would be allowed to regain access to your own personal computer.

Again in 2016, another hacking team known as the Shadow Brokers had penetrated the United States’ National Security agency, got hold of classified information in their data base and had audaciously pasted them all over the cyberspace. A calculated move that was meant to shame the highly regarded government intelligence agency.

Another of such high profile cyber attack was launched against Sony pictures in 2014 when the company was about to go public with a film titled “The interview”. The attack was as successful to the Lazarus Group as it was hugely embarrasing to Sony Pictures, with details of personal emails, closed door memos and fat pay checks of company executives completely exposed with impunity.

Just like the way Osama Bin Laden through the Al Queda terror group attacked the World Trade Center in New York as well as the Pentagon on September 11, 2001. A calculated move to show Americans that they are all vunerable to terror attacks. Cyber terrorists on their own also do select high profile government agencies and companies to attack, aside the Ransomware and a few others that are basically driven by monetry gains, others could be for nefarious reasons like Cyber bullying, political reasons, terrorism etc, and the most effective way to pass their message will be to attack such highly regarded establishments.

Records show that Ransomware attacks are on the rise, and there are indications as well that more of such Cyberattacks will be unleashed in the coming years with increased damage. Investigations also revealed that hackers took advantage of a security breach and algorithms that got leaked at the United States National Security Agency and are now using the tools as a vital weapon in attacking windows based operating systems.
