In this digital era, data security is becoming increasingly important. As technology evolves, so do the various threats that can endanger your data. One of the prevalent threats today is ransomware.
Therefore, it is crucial to understand what ransomware is and how to protect against it. This article will delve deeper into ransomware, including how it works, the types of ransomware, and tips for protecting yourself from ransomware attacks.
What is Ransomware?
According to IBM, ransomware is a type of malware (malicious virus) that attacks computer systems to obtain a ransom.
The victim’s data is encrypted so they cannot access files, databases, or applications. A ransom is then demanded to provide access back to the data.
Ransomware is often designed to spread across networks, targeting databases and file servers, which can quickly cripple an entire system used by an organization or individual.
How Ransomware Works
According to Trelix, ransomware uses asymmetric encryption, a cryptography method that uses a pair of keys to encrypt and decrypt files.
Hackers create a unique “key” to lock the files and important data. The hacker then provides the key to the victim once the ransom has been paid.
Ransomware can be spread in various ways, with one of the most popular methods being through emails sent to the victim.
Types of Ransomware
Ransomware can be categorized based on several factors, such as how it works, the targets it attacks, and the type of data it encrypts.
Here are some common types of ransomware:
1. Encrypting Ransomware
This is the most common type. Encrypting ransomware works by encrypting files on the victim’s device, making them inaccessible. The victim is then asked to pay a ransom to obtain the decryption key.
2. Screen Locker Ransomware
This type does not encrypt files but locks the victim’s device screen and displays a message demanding ransom. The victim cannot access their device until the ransom is paid.
3. Master Boot Record (MBR) Ransomware
This type attacks the Master Boot Record (MBR) on the victim’s hard drive, which contains information on how to boot the operating system. If the MBR is encrypted, the victim will not be able to boot their device.
4. Denial-of-Service (DoS) Ransomware
This type does not encrypt data but floods the victim’s server or network with traffic, preventing access to needed services. The victim is then asked to pay a ransom to stop the traffic.
5. Mobile Ransomware
This type is specifically designed to attack mobile devices such as smartphones and tablets. Mobile ransomware typically works by locking the device screen or encrypting files on the device.
Technological Advancements and the Rise of Cyber Attacks
Cyberattack using ransomware have increased in recent years. The advancement of technology has made malware tools more accessible to irresponsible individuals.
The presence of Ransomware-as-a-Service (RaaS), such as Ransom32, has also contributed to the rise in cyberattacks, making it easier for hackers to plan and execute cyberattacks.
This concludes the discussion on what ransomware is. As technology continues to evolve, it necessitates greater vigilance against cyberattacks. If you encounter suspicious emails, do not click on them immediately.
