The cybercrime world is ever-changing, and hackers are preparing for a future quantum computer that might make current encryption techniques useless. This is called “harvest now, decrypt later,” a rising phenomenon since cybercriminals steal encrypted data with hope for the time when, decrypted, it will become easy using quantum computers. Businesses must be aware of this new threat and use measures of proaction in their data protection.
Encryption has been one of the most essential practices that organisations have been carrying out for years, keeping any of the sensitive information being used to communicate, financial records, and personal information. New advances in quantum computing, however, create a potential danger that today’s encryption would be relatively easy to break in the near future. Hackers are aware of this and are more aggressively collecting encrypted data that will wait for the quantum computers’ ability to break down cryptographic codes.
Already, it’s the reality of cyberattacks. Today, more than 70% of ransomware attacks include exfiltration of data before encrypting it. Cybercriminals are banking on quantum computing ultimately making decryption of taken data possible, no matter how safe they are today.
Threat from Quantum Computing to Encryption
There is a fundamental difference between quantum and traditional computing. In a classical computer, a bit is either one or zero.
