A break-in into one of the most secured systems in the world, the news is viral and the person, our hacker, feels like he’s accomplished something big, something impossible. Maybe that’s the intention or maybe it is not. Money, recognition, or whatever be the reason, the number of cybersecurity or otherwise known as computer security attacks has been on the rise during the past few years. Here, we’ll take a look at a couple of the best ones so far.
This was one of the most recent cyberattack that shook the whole world. The WannaCry attack broke out in May 2017. Through this attack, the WannaCry ransomware crypto worm targeted systems that ran Microsoft Windows. It encrypted data from the systems and demanded payments in the form of Bitcoins as ransom. The attack was stopped within a few days of its discovery by the emergency patches which were released by Microsoft. The discovery of the kill switch prevented the already affected computer systems from further spreading the WannaCry.
Surfaced in August 2016, this was a mysterious group of hackers who claimed to have broken into the spy tools of the NASA-linked operation called the Equation Group. The group produced a sample of the data acquired and then tried to auction it. Later during the same year, they followed up with their break-ins with leaks during the Halloween and on Black Friday.
In April 2017, the group released details concerning its major break-in which included information about ExternalBlue, a Windows exploit which was one among the so-called NASA tools. They have then used the same to launch two major ransomware attacks against computer systems: WannaCry and NotPetya or Goldeneye or Petya. The whereabouts of the group have still not been uncovered.
This cyber attack was launched in 2001 and is considered to be one of the worst attacks caused by spreading a computer worm. It attacked Microsoft’s Internet Information Server through a buffer overflow. Though Microsoft had overseen the scope of such an attack and had issued a security patch for the same, many organizations failed to apply them. The result was disastrous; the number of systems affected by Code Red was between 1 million and 2 million.
These cyberattacks have clearly showed that computer security is always at risk and that measures to counteract damages must be taken to stay ahead of such malignant attacks in cyberspace.
