A security (or data) breach occurs when cyber criminals attack and bypass an organization’s security measure to gain unauthorized access to sensitive data and private information. Hackers infiltrate corporate security systems with different motives, such as copying business data or using it for more disastrous purposes.
Organizations face severe losses in the event of data breaches. When attackers gain access through the back door, they may expose private information, corporate secrets, financial details, and intellectual property. Far worse, companies who fall victims to data breaches may face legal sanctions from aggrieved clients.
In this article, we will highlight five major types of breaches that organizations should know about.
Cybercriminals often use malware or viruses to perpetrate cybersecurity attacks on individuals and companies. Malware often appears harmless, such as a text file, a pop-up ad, or executable software, but is programmed to infect a system and achieve malicious intentions.
Hackers trick unsuspecting users into downloading malicious software onto their personal or work computer. On installation of the malicious file, it may start to slow down your companies network, covertly steal business data, intercept shared data, or completely crash office systems.
- Password Attacks
Another common type of security attack is the brute force password attack. Hackers use special software to spy on users’ keystrokes or guess their passwords, and use it to gain access to their accounts or systems. Most times, they succeed when users have weak or easy-to-guess passwords, also when users use the same simple passwords on multiple accounts. This is why users should endeavor to use random, complex passwords to protect their accounts.
It’s not out of place today to see internet users get phished. To do this, hackers redirect users to official-looking websites and ask them to input their personal details to win prizes or gifts. Unsuspecting users may easily fall for this. However, the hackers at the backend are only collecting the submitted information with an intent to steal and extort. Phishing may result in the theft of important details like passwords, credit card numbers, and bank information.
- Denial-of-Service (DOS)
In Denial-of-Service attacks, hackers wilfully overload an organization’s system with fake requests so that the system becomes overwhelmed and malfunctions. Usually, in DOS attacks, targeted companies lose control of their systems experience a frustrating downtime that might take a while to recover from. Most often, hackers perform DOS attacks on media houses or political websites to protest, vent their grievances or make a statement.
Big companies such as law firms, banks, and hospitals are usually the primary targets of ransomware attacks. Cybercriminals forcefully take control of their corporate systems and block access to these essential business infrastructures and networks.
During ransomware attacks, companies lose access to the network, data, and information they need to run their day-to-day business. Subsequently, the attackers will demand a ransom from the company to lift the block before the company can gain access and be able to use their systems again.
Although this list is not exhaustive, these are some common data breaches organizations may fall victim to. To prevent these attacks, you’ll have to deploy robust data security measures and ensure that you review these strategies from time-to-time to correct vulnerabilities.
