Risks from cyber attacks can hurt regular people by losing their personal information and money. These are the most common cyber attacks:
- Malware: This is the term used for malicious software that thieves data, disrupts operations, or damages systems; under this are viruses, ransomware, and spyware. It results in personal information loss to individuals and organizations in terms of finance, reputation damage, and legal consequences.
- Phishing: It is an attempt to steal confidential information like passwords or credit card details by posing as some trustworthy source. This might result in identity theft and financial loss for the customer and data leakage with all its associated damages to the respective organization.
- Ransomware: after inspiring, a malware encrypts files, obliging one to pay for the decryption keys. Existent is the view that when people and organizations are locked out from very vital data, this may amount to much disruption or even financial ruin if they won’t or can’t pay the ransom.
- Social Engineering: Manipulation of people for the revelation of secret information or induction of performance of acts compromising security—this can mean unauthorized access, data breaches, and, hence, financial losses for the person or the institution.
- Zero-Day Attacks: The exploitation is done on a vulnerability in the software before the developers manage or are able to release patches for it. This can result in wholesale damages and loss due to the absence of defense at that particular moment.

Quantum computing has the potential to break many classical encryption algorithms, including RSA, which is widely used to secure online transactions and communication. Shor’s algorithm, a quantum algorithm, can factor large numbers exponentially faster than classical computers, making it a significant threat to RSA encryption.
Implications of Shor’s algorithm on RSA encryption:
Steps organizations should take to prepare for a post-quantum cryptographic landscape:
- Transition to post-quantum cryptography: Start exploring alternative cryptographic algorithms that are resistant to quantum attacks, such as:
- Lattice-based cryptography (e.g., NTRU, Ring-LWE)
- Code-based cryptography (e.g., McEliece)
- Hash-based signatures (e.g., SPHINCS)
- Hybrid approach: Use a hybrid approach by combining classical and post-quantum cryptography:
- Use classical cryptography for short-term applications and transition to post-quantum cryptography for long-term security.
- Key management: Implement key management practices that can handle the increased complexity of post-quantum cryptography, such as:
- Key generation and distribution
- Certificate management
- Key revocation and update mechanisms
- Network infrastructure updates: Upgrade network infrastructure to support post-quantum cryptography, including:
- Protocol updates for VPNs and other network protocols
- Updates to firewalls and intrusion detection systems
- Education and awareness: Educate employees and stakeholders about the implications of quantum computing on cryptography and the need for a transition to post-quantum cryptography.
- Collaboration: Encourage collaboration between industry leaders, researchers, and governments to develop standards and best practices for post-quantum cryptography.
- Monitor advancements: Continuously monitor advancements in quantum computing and their impact on cryptography, staying prepared to adapt to emerging threats.
