Introduction to Cyberattacks

Cyberattacks entail deliberate exploitation of computer systems, technology-dependent enterprises, and networks. They use malicious code to alter computer code, logic or data, resulting in disruptive consequences.

Common types include malware, phishing, man-in-the-middle attacks, denial-of-service, and SQL injection. Each type exploits different vulnerabilities, from user trust to software flaws.

While many assume cyberattacks originate from outsiders, insiders often pose significant threats. Disgruntled employees or those with access may conduct espionage or sabotage.

Cyberattacks can have substantial economic repercussions. The global cost of cybercrime is projected to reach $10.5 trillion annually by 2025, including damages and cybersecurity expenses.

Effective cybersecurity measures combine technology, processes, and education. Organizations must adopt a proactive approach, including regular risk assessments and a robust incident response plan.

In 2010, a cyberattack exploited printer firmware to gain network access, surprising even seasoned cybersecurity experts.
