The Must-Know Data Breaches: Case Study

By a data breach, we mean an incident of information stolen, accessed, or exposed without the permission of the information owner. The most common information that becomes a data breach victim is email addresses, constant customer data details, trade secrets, or credit card details.

Talking about the origin of recent credit card breaches or other types of breaches, they have been present since the beginning of time. In the digital world, it became prominent in the 1980s and grew immensely in the early 2000s.

In 1986, TRW, a global credit information corporation, was hacked, and around 90 million records were taken away. The same year, Revenue Canada became a victim of an information breach and one security data breach. Speaking of the impact of data breaches, it is of assorted types. For instance, one can lose a massive chunk of money when an individual is victimized.

For an organization, becoming a victim of an information breach means losing reputation and customers’ trust.

Here are some of the statistics related to the loss of data breaches:

Biggest Data Breaches

These figures show that data breaches are no less than a headache for individuals and cooperate.

How Does a Data Breach Happen?

A “data breach” occurs when a hacker or cybercriminal manipulates the data sources and extracts crucial information from that resource.

For instance, a hacker can access a computer or network in an unauthorized manner and steal information. Data can also be extracted by bypassing the network security protocols.

Some of the most common tools to make this happen are malware attacks, viruses, phishing, and Denial of Services. However, ways like payment card fraud and insider data leaks are also responsible for many data breaches.

Massive Data Breaches to be Aware of (Case by Case)

Here is a quick overview of some of the most talked-about and famous recent data breaches in 2021, out of which some resulted in exp data breach settlement and losses for the organization who were victims:

#1 – Facebook

Despite many cybersecurity breach prevention measures, Facebook has been victimized by data breaches a couple of times. It was reported that nearly 500 million users’ data were stolen and posted on a low-key hacking forum. The contact details like phone numbers and email addresses were revealed. It is as scary as it sounds.

Even the CEO of Facebook, Mark Zuckerberg, wasn’t able to save its private credentials from online predators. The data was leaked on the dark web for free. The only sigh of relief that those 540 million users have been the assurance that the finance and password-related information was not exposed.

Users from 160 countries fall into the trap of this recent data breach. The US was most affected as 32 million compromised accounts were from the US.

Facebook IDs, full names, locations, birthdates, bios, and – in some cases – email addresses were disclosed. A Facebook official revealed that it happened because of the vulnerability that the company handled in 2019. The data scraping process was adopted to make this happen.

#2 – Instagram

In May 2019, around 49 million records exposed online contained crucial information about Instagram influencers and celebrities. Users’ biodata, profile pictures, locations, and other essential details were disclosed. In 2021, it happened once again. But, this time, Instagram wasn’t at fault. It happened because of SocialArks, a Chinese Data-scraping company.

Because of cloud misconfiguration at the hands of SocialArks, around 318 million records were left unprotected in outer space. These records were of Facebook, Instagram, and LinkedIn.

#3 – LinkedIn

Around 500 million LinkedIn accounts were compromised in April 2021. It was said that a considerable sum in 4 digits (bitcoin) was used for negotiation. However, LinkedIn never explained the reasons and even tried to investigate the causes.

Common Causes for a Data Breach Incident to Take Place

  • Data mishandling by insiders: In this process, a company’s insider or trusted personnel steal customer data, sell it to peers, or use it for personal use.
  • Theft or loss of data: It refers to stealing or losing the source of the database. For instance, you have customer data stored in a laptop, and it got misplaced. Any other person got access to the laptop and stole the data. It can happen to paper-based data as well. Sometimes, it happens accidentally.
  • Denial of Service or DoS –  It occurs when a threat action overloads an organization’s system and network and prevents authorized personnel from accessing it. Mostly, the targets of this mode of data breach are large enterprises and MNCs.
  • Crimeware includes introducing assorted types of malware or planning social engineering attacks to steal information.
  • Ransomware involves taking the file of the targeted system/computer captive until the victim pays what is asked to access it.
  • SQL injection is where the hacker introduces arbitrary code to the web form of an online user. If the user fails to handle the form correctly, the code will enter the database and steal information.
  • Phishing is a type of social engineering attack and involves proposing the threat actor as a trusted source, contacting them via multiple means, and stealing crucial information.
  • Data breach via web applications: Access to the majority of web applications demand customary personal information like name, phone number, and emails. Hackers gain access to web applications and steal this information.
  • Attacks by Cyber-espionage: This type of data breach involves sending a malicious email to the affiliated actors to drill the system.
  • Skimming of payment card: If you use a debit or credit card, then you can be the victim of a data breach as criminals will place a skimming software/tool on the ATM or card reader and capture the card details.
  • Introduction of multiple errors: Sometimes, multiple errors like cloud storage misconfiguration and server misbehaving will lead to data leaks.
  • Point-of-sale intrusions: This type of data breach means/medium is mostly used in restaurants and controllers and involves information leaks from POS terminals and controllers.
  • Various other things: Ways like using a compromised email account and following the bogus directive are rarely used for hacking the databases.

What Troubles Can Cybercriminals Create With Stolen Data?

Well, one’s life can get into a serious mess if the stolen data falls into the wrong hands after a data breach target attack. They can use the information in various wrong ways. Here is a glimpse of the mess that they can create.

They can use the information to steal your money

This is the most common use of stolen data. Cybercriminals can steal your money directly or indirectly. They can:

  • Use the credit card and make the payment;
  • Directly withdraw money from one’s account and spend or invest it elsewhere;
  • Get things like medical treatment, avail of a home loan, or purchase expensive things using your money;
  • Use your information to avail the government perks;
  • Open an account;
  • Steal the rewards offered on the credit cards.

They will sell your information to a third party or expose it on the dark web

Your data has a lot of worth in the outer world. If you wonder where all these loan companies get your personal information, then it’s because a hacker has sold your information to them. Some hackers are so generous that they steal the information and release it on the dark web for free. In either case, the information owner is at a loss.

How Can You Help Protect Your Personal Data?

  • Organizations can update and review their data governance policies frequently and make changes as per the need of the hour.
  • Ensure that data classification and governance are at par with data privacy standards like HIPAA, SOX, and ISO 27001.
  • It is essential to do risk assessments frequently and spot the vulnerabilities in their infancy stage.
  • If you can afford a full-time data security expert, then it’s good. Else, outsource this service. Don’t ever try your hand in this domain. It is something that demands perfection and expertise.

Organizations can reduce the harm of data breaches by creating a viable disaster recovery plan. When there is an effective recovery, data can be recovered easily.

7 Viable Ways To Stay Protected Online on the Personal/Organizational Level

Considering the frequency at which data breaches occur, it’s imperative to adopt ways that will help an online user stay protected. Gladly, there are many ways available.

#1 – Don’t entertain anything unverified or unofficial while being online

While you’re online, make sure that you don’t open emails from strangers, open an unverified link, or even visit any unofficial website. Such online resources are mostly well-planned phishing attacks planned to steal personal information. Always entertain information or data coming from trusted individuals or resources in the online sphere.

#2 – Use updated system/software

Whatever devices or applications are used while being connected to the internet, make sure they all running over an updated OS. Outdated OS and systems will help cyberpunks in causing harm to your or your personal data/information because legacy systems are over-exploited, lack security patches against modern security threats, and fail to do quick error detection. Activate automatic OS updates to avoid any delays.

#3 – Always use strong passwords

Gone is the era of passwords like 1230 or john12. Easy-to-guess passwords are the greatest threat to personally identifiable information PII. Just as you protect your legal documents, you should be attentive enough to protect online documents or data with a powerful password. Also, avoid using the same password for multiple websites. We also recommend changing passwords frequently.

#4 – Try multi-factor authentication

Multi-factor authentication is an ideal way to prevent unauthorized access to email addresses, mobile devices, bank account details, and any other sensitive information stored online or on digital devices. This concept combines more than one login process together to strengthen online security.

#5 – Don’t get carried away with public WiFi

If you want to protect sensitive data and don’t want to compromise the user accounts, you need to stay away from public WiFi. Such WiFis are open to all, and cyberpunks use them to access personal data and plan a massive data breach.

#6 – Use viable security tools

There is no dearth of security tools in the market. All you need to do is to understand their power and use them in an intelligent way. For instance, you should use anti-virus software and scan the device at regular intervals. This tool will spot hidden vulnerabilities and alert you to take immediate action.

You can also use a VPN or proxy server to make the entire traffic fully encrypted. A proxy server is good for encryption applications, but it fails to match the offerings of a VPN. VPN is an advanced technology that protects traffic so much so that sensitive information, bank accounts, legal documents, online presence, and everything else that you do while being connected to the internet remains in a safe hand. VPN also helps in bypassing geo-restriction.

Using a firewall is also a great way to avoid authorized access to devices such as computers, IoT, phones, and so on.

#7 – Delete your user account information from unverified devices

First of all, you should never use someone else’s computer or device to stay connected. But, if you have to use another device, make sure you log out from that device immediately. Never let any confidential details be saved on unverified devices.

The effective utilization of these practices will help you to stay protected as you browse the internet.

What Should You Do if Your Personal Data is Exposed?

We know that it is a heart-breaking and shattering thing to know that your personal data has been stolen. Thoughts of getting robbed, blackmailed, or exposed will run through your mind, and it is about to happen. But, you need to maintain your sanity as you are not alone in this. Many leading firms have also faced it.

This is what a prey of data breach must do soon after the attack.

  • Figure out what kind of attack has happened. Whether your personal information has been stolen or financial credentials have been compromised.
  • Once you figure out what has been stolen, take remedial actions immediately. Change all the passwords and update your account details. In case of financial data theft, contact your bank and report the incident. Ask for an inquiry as well.
  • Enable the two-factor authentication on all your accounts for added security. With this, you will be notified when someone is trying to gain unauthorized access to your dataset.
  • If you feel that a crucial dataset has been stolen, it is better to hire a security expert to find the root cause and recover the data. This is primarily the case with organizations and businesses. But, individuals with heavy loss can also take up this way.

How Can You Recover If Your Data Is Exposed In a Data Breach: Steps to Take on Your Own

  • Find out the type of data hampered. In the US, companies have to inform the end-user about the data breach and the kind of information stolen. If this is not the case where you reside, try to figure out this first to determine how much damage is about to happen.
  • Contact your bank or other financial institutes. If your debit or credit card is compromised, block them as soon as you spot a breach.
  • Change all the current passwords. Some attacks are visible immediately, while few take time to come to the surface. So, it’s better to change all your passwords once you face a data breach.

Keep an eye on any suspicious activity. If the attack was made by malware, then you might face its impact after some time as well. We will also suggest hiring an expert and getting a thorough check done so that if there is anything hidden, it will come to the surface. As a prevention, you should implement powerful anti-virus software in your system.
It will add an added layer of security. Using a VPN is also a great way to enhance system security and stay safe in the virtual space.

The Bottom Line

Data breaches are common and are likely to target all of us. However, one can save its neck by being a little extra vigilant. It is wise not to entertain any email, post, or message with unknown or unauthorized information. Keeping devices and software updated is also very crucial. Doing regular security audits can save tons of hassles. So, stay aware and informed.
