Cyber Crime

Cybersecurity refers to the practice of protecting computers, networks, systems, and data from digital attacks. These attacks can come in various forms, such as malware, phishing, ransomware, and hacking attempts. The goal of cybersecurity is to ensure the confidentiality, integrity, and availability of information and systems.

Here are some key aspects of cybersecurity:

1. Confidentiality: Protecting data from unauthorized access. This involves encryption, access controls, and secure communication protocols.
2. Integrity: Ensuring that data is accurate, reliable, and trustworthy. Techniques like checksums, digital signatures, and data validation are used to maintain integrity.
3. Availability: Ensuring that systems and data are accessible to authorized users when needed. This involves implementing redundancy, backups, and disaster recovery plans.
4. Authentication: Verifying the identity of users and systems to prevent unauthorized access. This includes using passwords, biometrics, multi-factor authentication, and certificates.
5. Authorization: Granting appropriate permissions to users based on their roles and responsibilities. This prevents unauthorized users from accessing sensitive information or performing certain actions.
6. Network Security: Protecting networks from unauthorized access, attacks, and vulnerabilities. This includes firewalls, intrusion detection systems, and secure network configurations.
7. Endpoint Security: Securing individual devices such as computers, smartphones, and IoT devices. This involves antivirus software, encryption, and device management policies.
8. Incident Response: Planning and responding to cybersecurity incidents such as data breaches or cyberattacks. This includes identifying, containing, mitigating, and recovering from security incidents.

Cyber Criminals

Cybercriminals are individuals or groups who engage in illegal activities using computers, networks, and digital technologies. They exploit vulnerabilities in systems and networks to gain unauthorized access, steal sensitive information, disrupt services, and commit various types of cybercrimes. Here are some common types of cybercriminal activities:

• State-sponsored groups targeting organizations in other countries
• Hacking Groups out to target companies to make them pay ransom
• Kids in their rooms doing illegal hacking

Note: Cryptocurrency is money represented in digital form instead of physical. There are many different Cryptocurrencies, some very widespread like Bitcoin, and others smaller and unknown to most people. These currency models relies on strong cryptography and public ledger systems to keep track of transactions and how much currency is on the market.

Catching Cyber Criminals

Catching cybercriminals involves a combination of technical expertise, investigative techniques, collaboration between law enforcement agencies and cybersecurity professionals, and international cooperation. Here are some steps and strategies commonly used to catch cybercriminals:

Cyber Criminals can stay anonymous with trivial means, and typically easy to avoid getting caught. When attackers do get caught, it is often because of mistakes made by the attackers themselves, for example as a result of becoming complacent. There is also a great deal of potential for law-enforcement to use caught cyber criminals to rat out others in the industry.

Law enforcement do, however, have many challenges in tracking down cyber-crime. You might see attack traffic coming in from a system residing in UK, and when taking down this system, you realize it was being remotely controlled by e.g. another system in India. Cooperating with law-enforcements across borders, you might be able to get to the system in India, but only to realize it was again remotely controlled through e.g. Pakistan.
