The 5 biggest cyber attacks of the past decade

A cyber attack is any type of offensive action that targets computer networks or devices. Cyber attacks can be carried out by individuals, groups, or governments, and their motives can range from getting revenge to political or ideological gain. Some of the most common types of cyber attacks are denial-of-service attacks, malware infections, and phishing scams.

Cyber attacks are becoming increasingly common as the world becomes more reliant on computer networks and devices.

2010: Stuxnet attacks Iranian nuclear facility

In 2010, a computer worm called Stuxnet was used to attack an Iranian nuclear facility. This was one of the first known instances of cyber warfare. The Stuxnet worm was able to damage centrifuges at the Iranian nuclear facility, set back their nuclear program by several years.

This incident showed just how powerful cyber attacks can be. They can be used to damage physical infrastructure and cause havoc without any troops ever setting foot on enemy soil. Cyber attacks are a new and increasingly popular form of warfare that countries must learn to defend against.

2012: Operation Ababil takes down Saudi Arabian oil company

In 2012, the Saudi Arabian oil company was taken down by Operation Ababil. This was a cyber attack that targeted the company’s computer systems, causing them to crash. The attack was carried out by a group of hackers known as the “Saudi Cyber Caliphate”.

The Saudi Cyber Caliphate is a group of hackers who have pledged their allegiance to the Islamic State. They have carried out a number of attacks against Saudi Arabian targets, including government websites and banks.

The Operation Ababil attack took place on August 15th, 2012. The hackers used a piece of malware called Shamoon to infect the computer systems of the Saudi Arabian oil company. This malware caused the systems to crash and prevented them from being able to restart.

The impact of the attack was significant, with production at the Saudi Arabian oil company being halted for several days.

2014: Sony Pictures Entertainment suffers data breach

In November 2014, Sony Pictures Entertainment (SPE) suffered a cyber attack that resulted in the release of large amounts of sensitive data. The attackers gained access to SPE’s servers and networks by exploiting several vulnerabilities, including an outdated software version and weak passwords. This allowed them to obtain confidential information such as employee Social Security numbers, salary information, and email correspondence. In addition, several unreleased films were leaked online as a result of the breach.

The attack had a significant financial impact on SPE, as the company had to spend millions of dollars to investigate and clean up the data leak. In addition, SPE’s stock prices fell sharply after news of the breach broke. The incident also damaged SPE’s reputation, as many people questioned the company’s ability to protect its customers’ data.

2016: Dyn DNS attack brings down major websites

In what’s being called the biggest cyberattack in history, major websites including Twitter, Netflix, and Reddit were brought down today by a distributed denial of service (DDoS) attack on Dyn, a major DNS provider.

The attack began at 7am ET and affected users on the East Coast of the United States. Dyn said that it had “mitigated” the attack and restored service by 9:20am ET, but that it was still investigating the issue.

The attackers used a Mirai-based botnet to target Dyn’s DNS servers with a DDoS attack, flooding them with traffic and causing them to go offline. This is the same botnet that was used in last month’s massive DDoS attack on KrebsOnSecurity.com.

Dyn says that it is still investigating the incident and working to prevent future attacks.

2017: WannaCry ransomware attack affects hospitals and businesses worldwide

The WannaCry ransomware attack hit businesses and hospitals worldwide in May of 2017. The cyber attack caused widespread panic and disruption, as critical systems were taken offline. Hospitals were forced to cancel surgeries and appointments, and businesses lost access to important data. The attack was a wake-up call for many organizations, who realized that they were not prepared for a major cyber attack. Since then, many organizations have beefed up their cyber security measures to prevent another WannaCry-type attack from happening again.

In conclusion, the future of cyber attacks is very uncertain. Despite the best efforts of security professionals, it is inevitable that some clever hackers will always find a way to get through even the most sophisticated defenses. The best we can do is to try to stay one step ahead by constantly improving our security measures and remaining vigilant.
