An info-rich database is one of the most essential assets of a company or organization. Shield your data from cyber threats with robust ransomware encryption solutions. To protect it from unwanted changes, experts rely on the latest applications and updates. EDR, MDR, and XDR reinforced with SIEM and SOAR are some examples: These programs secure endpoints (mobile phones, USB ports, laptops, PCs, and more) with prompt measures to quarantine, destroy, or nullify threats.
What is Ransomware Encryption?
Ransomware encryption is a malicious intrusion of computer systems wherein cybercriminals encode files and bar users out of their devices: Millions of dollars are demanded in exchange for the decryption process. In addition, a specific time frame is provided for the entire process to conclude, the results of which are data elimination or transfer to secondary sources, such as dark web.
Ransomware Encryption – The Process Within
Encryption is an essential feature of OS (operating systems) that can be exploited by hackers for nefarious purposes. The basic security structure and functionality can be compromised using a private key. There are two types of encryption techniques used by cybercriminals:
- Symmetric
- Asymmetric
Symmetric encryption uses one key to encrypt and decrypt data. It is one of the oldest techniques known to cybersecurity experts as well as hackers. The key can be a number, word, or a mix of random letters. For example, ‘Let’s walk’ can be converted to ‘d31GD3m439FS0ffFgle30F’ in encrypted form. The recipient and sender should know the key that can encrypt and decrypt the messages.
Some of the common symmetric algorithms are:
- AES-128
- AES-192
- AES-256
Benefits of Symmetric Encryption
- Quicker
- Identity Verification
- Easy to Execute & Manage
Asymmetric encryption, also known as public key cryptography, is an advanced method compared to the preceding one. This process uses two keys to encrypt a plain text: The passkeys are transferred online over the web to restrict intruders from embezzlement. Because a person with the secret key can decrypt the message, another key is available for security reinforcement.
A public key is made available to individuals who want to forward messages. Moreover, a public-key-encrypted message can be decrypted with a public key. Security of the key is not required. Asymmetric encryption is used in communication channels over the network. Some of the popular encryption algorithm keys are:
- ElGamal
- RSA
- DSA
- PKCS
Benefits of Asymmetric Encryption
- Two Keys
- Easy Communication
- Scalable
Gaining Access to Systems
Ransomware, like other malwares, can access digital systems in different ways:
Phishing Emails
Hackers send an encoded message as an attachment or an infected email that spreads malware with a click. Once the malicious software is downloaded, the data-encryption operation begins, with the user not knowing its functioning. Once the data is encrypted, the hacker blacks out the screen with a warning message. The data is only retrieved back once the ransom is paid or the hacker is caught.
Remote Desktop Protocol
In this process, a cyberattacker who has surmised the user’s credentials (ID and password) can use them to manage and access the user’s system without their knowledge. The hacker can download the malware easily and keep the machine under its control. Others may infect systems directly like EternalBlue and WannaCry vulnerabilities. Most ransomware alternatives have multiple vectors.
Ransom Demands
Once the file encryption is finalized, the hacker makes a huge demand of cash, connected to thousands or millions. The payment is usually demanded in dollars or cryptocurrency, such as Bitcoin. If the ransom is delivered, the hacker will provide the private key used to protect the symmetric encryption key. The information is added to the decryptor program that uses it to reverse the process and restore the files.
Types of Ransomware Attacks
There are several types of ransomware threats looming over the Internet.
- Double Extortion
- Triple Extortion
- Locker Ransomware
- Crypto Ransomware
- Wiper
- Ransomware as a Service (RaaS)
So, are you ready to protect your data against ransom threats?
