Distributed denial of services (DDos attack)
In order to cause a denial of service, cybercriminals bombard a target website or network with requests until its resources are inaccessible to authorized users. A denial-of-service (DDoS) assault can be used to distract IT or security personnel while malware is loaded, even though it is not a data breach in and of itself.
Ransomware
Ransomware is a sort of malicious software that enables attackers to encrypt data on a target network and require a ransom to unlock it. This could be coupled with the attacker accessing, copying, or shipping data from the network before encrypting it & threatening to release the data if the ransom is not paid in the event of a data breach. It’s crucial to remember that payment does not ensure that the data will be returned safely.
SQL Injection
SQL databases are widely used in web applications to store sensitive data, including credit card numbers, users, and passwords. Through the use of security holes, hackers can manipulate an application’s database queries in a SQL injection attack, giving them access to, and the ability to change or remove data.
Phishing
A cybercriminal may pose as a reliable contact and get in touch with a victim via text, phone, or email. After that, the attacker may trick the victim into directly giving over data, or they may persuade them to download malware or a virus – frequently by opening an attachment or clicking a link.
Criminal insider
An individual who misuses their position to leak data is known as a criminal insider. This person is typically an employee or contractor who may or may not have legal right to access sensitive information. Usually, they are motivated by self-interest or a desire to undermine the organization.
Accidental insider
On the other hand, an accidental insider is a person who inadvertently results in a cybersecurity breach. Examples of this include falling for a phishing scheme, utilizing a personal device that is not allowed, or using bad password management. Workers who lack even the most basic cybersecurity training pose a risk to their organization.
Physical theft or loss
Your company could be at danger from any physical device that contains sensitive information that is lost or stolen, such as an unprotected laptop, hard drive, mobile phone, or USB.
Example of data breaches
Small organizations and individuals are equally vulnerable to data breaches, despite the perception that big companies are the primary targets—possibly because they garner media attention when they occur. The following examples of data breaches show the extent of the harm they can create.
Cam4
Early in 2020, one of the worst data breaches ever documented happened to Cam4, a modest company that offers pornographic streaming services. It was possible to disclose 10.88 billion user records due to a misconfigured database. Customers’ names, email addresses, and chat transcripts, among other personally identifiable information (PII), were among the stolen data.
Yahoo
In 2016, Yahoo, a well-known email provider, revealed two data breaches that impacted each of its three billion user accounts.
A phishing email started the initial attack. The names, email addresses, passwords, dates of birth, and phone numbers of users were all accessible to attackers. The breaches reduced the company’s market value by an estimated $350 million, and after the disclosures, a number of shareholders filed lawsuits.
Equifax
The Equifax hack was completely avoidable. Hackers took advantage of an unpatched, but known, vulnerability in a technology that was utilized to create the web application for the credit reporting organization in 2017.
More than 143 million people’s personal information, including names, addresses, dates of birth, and even information from driver’s licenses, was exposed. According to the firm, the hack cost $1.4 billion. Interestingly, there have been no reports of fraud or identity theft linked to the event.
What are the laws around data breaches?
Different rules & regulations may apply depending on where you or your clients are located in the world when it comes to data privacy. It is imperative that you are aware of the necessary actions to take in the event that a data breach occurs at your company. This will be impacted by:
- Where you conduct business
- Where personally identifiable information (PII) is stored
- Which kinds of PII does your business keep?
- Where the specific PII data subjects are located
The General Data Protection Regulation (GDPR)
- GDPR, which is widely regarded as the most stringent set of data privacy laws globally, was implemented by the European Parliament in May 2018. The following is a quick summary of the requirements concerning data breaches:
- It is necessary to protect personal data against “unauthorized or unlawful processing.”
- When someone’s data could be damaging to the data subjects, you are required to notify the “collapse, loss, alteration, unauthorized disclosure of, or access to” it to the nation’s data protection agency.
- In the UK, when a breach is discovered, it has to be reported to the ICO within 72 hours.
- You also have to notify persons in case a breach puts them in danger. As soon as possible, this needs to be completed.
- You have to document a data breach even if it does not need to be reported.
Regulations in the US
Although there isn’t a federal legislation in the US that governs notification in the event of a data breach, you should be aware of the terms of the state-specific data privacy laws. The Health Insurance Portability & the Accountability Act (HIPAA) & California Consumer Privacy Act (CCPA) are two well-known US regulations.
What should I do if my data is stolen?
In the unfortunate event that you find out about a data breach, there are a number of steps you may do to strengthen your security:
- Reset the passwords for every account you have. Regardless of whether a particular account was compromised or not, it is advisable to update all of your passwords. Select lengthy, intricate passwords, and where it’s feasible, turn on two-factor authentication (2FA).
- Speak with your bank or other lending companies. Inform them of the data breach that affected you and request that they look into any possible fraudulent activities. Get fraud alerts, replace your cards, or modify your account information.
- Make a software update. To strengthen any possible weaknesses, install any outstanding updates.
- Take the initiative. Make sure you are aware of potential dangers and are able to recognize clues that point to questionable behavior. If someone obtains sufficient information about you through a data breach, you may also be doxed. Keep an eye out for any upcoming data problems.
How to prevent a data breach
The average cost of a lost or stolen record in a data breach in 2020 was $146, thus a major breach might have disastrous effects, especially for small businesses. Fortunately, there are a lot of things you can do to increase the difficulty with which fraudsters can access your data and compromise your systems. Also check data analyst companies
To make sure you have a strong security foundation in place, take the following actions:
1. Take care of the basics
- Set up firewalls. A firewall, your network’s initial line of security, will stop any unwanted traffic and harmful malware from getting inside.
- Set up an antivirus program. In addition to proactively blocking, detecting, and eliminating threats like malware, a complete commercial antivirus solution should also offer anti-phishing defense.
- Set up an encryption program. Make sensitive data illegible to prevent unwanted individuals from accessing it.
- Employ a zero trust network, or VPN. To prevent data from being captured by an unauthorized party, send information only over secure channels.
- Make secure passwords. mandate that each user account have a complicated, one-of-a-kind password, and that passwords be changed on a regular basis.
2. Promote employee awareness
- Train staff members. Emphasize the value of cybersecurity and provide staff with the necessary training to identify risks to it and take appropriate action.
- Talk to each other. Remind staff members frequently of the risks involved with opening attachments or links in emails from senders they are not familiar with.
- Promote responsibility. Ensure that each employee understands their own duties and responsibilities in safeguarding the company’s data.
3. Update your starters and leaves process
- Orient new hires. Determine the precise information, hardware, and access rights that new hires require.
- Deal with departing employees. Implement a controlled exit strategy for departing employees that includes timely group password resets.
- Examine the devices that were returned. When necessary, securely erase or wipe data.
4. Manage ongoing maintenance and planning
- Keep yourself updated. Regularly scan your devices and network to see whether any updates are required. As soon as you can, install any updates or patches from reputable software providers. Think about utilizing software that can notify you when something needs to be done or automate this procedure.
- Get ready. Make an emergency response plan that describes what you do in the event of a data loss, theft, or breach.
- Produce duplicates. Make regular backups of your data so that, in the event of an emergency, you can quickly restore it.
Which vulnerabilities could result in a data breach?

These are a few of the most prevalent weaknesses along with solutions. Also check Data Recovery Software
weak or stolen passwords
Cybercriminals can easily profit from weak credentials. Make it mandatory for staff members to utilize two-factor authentication (2FA) on critical accounts and to create distinct, complicated passwords for each account.
Unsecure mobile devices
It is common for employees to use their own devices for work, therefore you will have much less control over security protocols like passwords, device access management, and public Wi-Fi usage. Establish a policy for employees to bring their own devices (BYOD) that outlines specific expectations, and dedicate some training time to highlighting potential risks.
Outdated security
Your company is at danger if you are using software for which there is an update or patch available but it is not installed. Make certain that all software has been updated and completely patched.
