You might not think about it often, but the internet is vulnerable. Hackers are always looking for new ways to break into our systems and steal our data. That’s when cyber attacks happen and happen all the time, but some stand out more than others. The biggest cyber attacks in history have affected everything from individual users to large companies.
This article will look at some of the biggest cyber attacks ever made, from the RockYou hack in 2009 to the massive Uber breach in 2016.
Each of these major cyber attacks had a different motive and caused different levels of damage. But one thing they all have in common is that they were all incredibly costly for the companies and individuals involved. So if you’re interested in learning more about them, read on.
1. Rock You: One of the Largest Data Breaches in History
In 2009, music retailer Rock You was the victim of a cyber attack that resulted in the theft of 32 million user passwords. Hackers used a phishing email to get access to over 32 million accounts. The passwords and email addresses were then posted online.
This was one of the largest data breaches in history at the time, and it put the personal information of millions of people at risk. The hackers gained access to the company’s database using stolen login credentials, and they made off with the personal information of users who had registered on the site between 2004 and 2009.
This was a huge blow to Rock You, and it took them years to recover from the attack. They were forced to invest in enhanced security measures, and they also had to rebuild their customer database from scratch.
2. Uber: Another Massive Data Breach
The Uber data breach was another major attack. In 2016, hackers accessed the personal information of over 57 million Uber users. The data included names, email addresses, and phone numbers. It was one of the most successful startups in the world at the time and suffered a massive data breach.
57 million user accounts were compromised, including the personal data of drivers and passengers. This was a huge blow to the company, and it took them a long time to recover from the attack.
The consequences of the breach were far-reaching. Not only did Uber have to deal with the fallout from the breach itself, but it also faced lawsuits from drivers and passengers who had their personal data stolen.
To make matters worse, it was later revealed that Uber had known about the breach for months before they announced it to the public. This was a major PR disaster for the company and damaged its reputation.
3. The Yahoo Data Breach
When it comes to cyber attacks, the Yahoo data breach is up there with the worst of them. While Yahoo only confirmed the breach in 2016, it’s thought that the attack may have taken place back in 2014. Yahoo has since been fined $35 million for failing to disclose the attack to its users. If you remember, Yahoo was hacked in 2013, and the personal information of over 1 billion users was stolen.
This was a major hack and is still one of the largest data breaches ever recorded. In addition to users’ email addresses and passwords, the hackers got their dates of birth, phone numbers, and security questions and answers. The company has been criticised for not protecting its users’ data. The hackers even managed to get data from Yahoo’s financial partners.
This is a huge wake-up call for all of us. We need to be more careful about the information we share online and make sure our passwords are strong and unique.
4. Adobe: One of the Most Costly Cyber Attacks
You might not know this, but the Adobe cyberattack was a huge breach. In 2013, the company was hacked, and the personal data of 38 million customers was compromised. This included names, credit card numbers, and expiration dates.
This was a huge blow to Adobe, not only because of the scale of the attack but also because it was such a costly one. The company had to spend millions of dollars on remediation and security measures to protect its customers’ data.
Adobe is by no means the only company to have been targeted by cybercriminals. But its experience is a cautionary tale for others thinking about underestimating the risk of being hacked.
5. Sony’s PlayStation Network Attack
You might remember the Sony PlayStation Network Attack from a few years ago. It was one of the most damaging cyber attacks on a major corporation. The Sony PlayStation Network attack was a major breach as well. In 2011, hackers accessed the personal information of over 77 million PlayStation Network users. This included names, addresses, birthdates, and credit card numbers.
Hackers managed to break into Sony’s servers and steal the personal information of millions of users, including their credit card numbers. This was a huge blow to Sony, not only because of the financial damage it caused but also because it damaged its reputation.
The attack forced Sony to take down the PlayStation Network for more than a month, and they had to issue a recall for all of the consoles that had been sold up to that point. It was a disaster for Sony, and they learned their lesson about how important it is to have strong security measures in place. The company’s PlayStation Network was hacked, resulting in the theft of personal data from millions of users.
As we continue to become increasingly reliant on technology, it’s only going to become easier for hackers to launch cyber attacks.
6. The Mueller Report Cyberattacks
The Mueller Report was released to the public on April 18, 2019. It detailed the extent of Russian interference in the 2016 United States presidential election.
Among other things, the report stated that Russian hackers had targeted email accounts belonging to Hillary Clinton’s campaign chairman, John Podesta, and the Democratic National Committee. They also breached the systems of a voting software company and stole information about millions of voters.
This was one of the biggest cyber attacks in history, and it greatly impacted the election outcome. It revealed several massive cyberattacks that the Russian government orchestrated.
These cyberattacks were designed to meddle in the 2016 U.S. presidential election, and they were shockingly successful. The report detailed how the Russians used social media to spread disinformation and sow discord among Americans.
But that’s not all. The Mueller Report also revealed several other cyberattacks, including:
– The hacking of the DNC
– The hacking of Hillary Clinton’s campaign chairman
– The hacking of a voting machine company
– The targeting of state election systems
7. Equifax: One of the Most Invasive Cyber Attacks to Date
You may not have heard about the Equifax hack, but it was one of the most invasive cyber attacks in history. Equifax is a credit reporting agency that holds sensitive information about people’s credit history.
Hackers were able to gain access to Equifax’s systems in May 2017, and they managed to steal the personal information of over 145 million people. This included names, social security numbers, addresses, and driver’s license numbers.
Equifax didn’t reveal the hack until September 2017, which caused much damage to its reputation. People were angry that the company had waited so long to tell them about the breach, and they were worried that their personal information would be used for identity theft.
By now, you should know the importance of cybersecurity and how to protect yourself from attacks. Cybersecurity is important, and you should always be aware of the threats.
8. Ransomware Attack on Royal Mail Servers
The Emotet malware was discovered on Royal Mail systems in November of last year, and that’s when it all started. Subsequently, an associate perpetrated a ransomware attack against Royal Mail in early January 2023 using LockBit Ransomware-as-a-Service (RaaS). The printers at a distribution center close to Belfast, Northern Ireland, started printing the demands of the ransomware group after this attack.
The attack mostly impacted foreign delivery, and early recommendations suggested using different carriers. Due to Royal Mail’s designation as Critical National Infrastructure (CNI) by the UK government, the National Cyber Security Centre (NCSC) and other UK authorities were expected to engage promptly.
It is common practice for LockBit users or affiliates to encrypt data on the target servers and then exfiltrate it, giving them two ways to extract sensitive information. Presumably, this occurred with Royal Mail, albeit reliable details are still lacking.
Checking the LockBit dark web and message boards where victims must pay or get instructions has yielded the most relevant information. Like any community, the LockBit ransomware infrastructure operates with a level head. Along with new software, they provide discounts and cyber security advice to evade capture and announce a major update, LockBit 3.0.
The Royal Mail released an updated statement regarding their efforts to restore all services on 6 February. Their goal is to complete recovery, although they have nearly restored all services. While investigations will continue, apprehending those responsible for these acts can be challenging and time-consuming, demanding a lot of resources.
9. Cyberattack on BMW Munique Motors
The Play Ransomware organization had taken responsibility for two previous cyberattacks; the most recent one was on BMW France, and this one is on BMW Munique Motors. If their ransom demand was not satisfied by April 9, 2023, the organization threatened to reveal stolen material on the dark web in an ultimatum. Reportedly, bank information, contracts, and client documents were among the exposed data sets.
Once again, the esteemed German automaker’s reputation hit in 2022 when hackers gained access to BMW France’s social media accounts in a massive cyberattack. Following in the footsteps of the notorious Cyclops ransomware, the Knight ransomware family surfaced in August 2023. The fact that this threat actor provides both standard and “lite” payloads demonstrates a new degree of complexity in cybercrime strategies.
Knight ransomware uses extreme coercive measures to obtain payment and prevent public data dumps. It operates as a multi-extortion group and uses a TOR-based blog to disclose victim identities alongside any exfiltrated data. On the RAMP forum, this group has promoted and sold its services vigorously.
10. The Guardian Cyber Attack attack
A ransomware attack crippled the UK newspaper The Guardian on December 20, 2022. While internal systems were disconnected and prioritized, the immediate result was that the corporation asked people to work remotely.
It impacted every system in the office, from the cash registers to the internal staff communication tools. The newspaper’s print edition seemed untouched at the time, although sources have acknowledged that it was very close and, in certain instances, manual operations were necessary.
Misconfigurations, social engineering, phishing, or human mistakes are the true causes of most attacks. The next step is to use pre-made malware programs or ransomware as a service.
It was determined by the investigating firm, KnowBe4, that email phishing was the initial vector of attack in this case. Details are still lacking. However, it is understood that some employee data was compromised, maybe to get the ransom money. The Guardian notified the UK Information Commissioner’s Office (ICO) within 72 hours.
11. Kid Security: More than 300 million records exposed
Due to improperly configured Elasticsearch and Logstash instances, the widely used parental control tool Kid Security—which enables parents to oversee and manage their children’s online safety—leaked user activity logs to the Internet for over 30 days.
The compromised data was initially discovered in mid-September by SecurityDiscovery’s Bob Diachenko, a security researcher. More than 300 million records were compromised, including 31,000 email addresses and 21,000 phone numbers, according to CyberNews. Additionally, some credit card information was leaked.
Evidence of data access suggests that the Readme bot “partially destroyed” the open instance and added a ransom note containing a Bitcoin wallet address to be paid in return for the contents.
