South African telecom provider Cell C disclosed a data breach following a cyberattack

Security Affairs

The company founded in 2001 offers prepaid and postpaid mobile plans, data bundles and internet services, fiber broadband, roaming and international calling, SIM-only plans and device deals. Unlike other extortion group, the gang doesnt encrypt data, but focuses on data theft to speed up its activity. Victims include AMD and Keralty.

Calculating the Benefits of the Advanced Encryption Standard

Schneier on Security

NIST has completed a study -- it was published last year, but I just saw it recently -- calculating the costs and benefits of the Advanced Encryption Standard. And I certainly agree that the benefits of a standardized encryption algorithm that we all trust and use outweigh the cost by orders of magnitude.

NIST’s Post-Quantum Cryptography Standards

Schneier on Security

The idea is to standardize on both a public-key encryption and digital signature algorithm that is resistant to quantum computing, well before anyone builds a useful quantum computer. NIST is an old hand at this competitive process, having previously done this with symmetric algorithms (AES in 2001) and hash functions (SHA-3 in 2015).

Encryption: How It Works, Types, and the Quantum Future

eSecurity Planet

Encryption and the development of cryptography have been a cornerstone of IT security for decades and remain critical for data protection against evolving threats. While cryptology is thousands of years old, modern cryptography took off in the 1970s with the help of the Diffie-Hellman-Merkle and RSA encryption algorithms.

What is encryption? And why it matters in a VPN

Malwarebytes

Encryption is a term used to describe the methods that hide the true meaning of messages using code, especially to prevent unauthorized access to the information in the messages. Not all users of virtual private networks (VPN) care about encryption, but many are interested and benefit from strong end-to-end encryption.

Types of Encryption, Methods & Use Cases

eSecurity Planet

Encryption scrambles data to make it unreadable to those without decryption keys. Proper use of encryption preserves secrecy and radically lowers the potential damage of a successful cybersecurity attack. Encryption algorithm types will provide an overview of the mathematical algorithms used to encrypt data (AES, RSA, etc.),
