The Components of a Cyber Attack

Cyber attacks have several stages, including reconnaissance, initial access, attack deployment, expansion, payment collection and cleanup. Understanding these components is crucial in protecting personal information and preventing financial loss or reputational damage.

Reconnaissance

In the initial phase of a cyber attack, hackers engage in reconnaissance to collect as much information about their target as possible. They meticulously study the target’s behaviours, defences, and vulnerabilities without alarming anyone that something malicious is on the horizon. Clever techniques like social engineering—tricking employees into revealing sensitive information—or conducting online research provide these attackers with valuable insights for crafting their attack strategies.

Hackers often scan systems for weak spots, such as outdated software or unprotected entry points. Gathering data during this stage can be alarmingly simple, especially if security measures aren’t up to date or if staff members are unaware of how precious their casual day-to-day info can be to prying eyes.

This silent watching and learning sets the foundation for more aggressive stages that follow, making it vital to have robust network security measures in place early on.

Initial Access

After conducting reconnaissance, cyber attackers move on to gaining initial access to a system. This is the crucial first step in their operation, where they exploit vulnerabilities or use social engineering tactics to infiltrate the target’s network. Once inside, hackers can quietly establish a foothold and begin their attack deployment without detection.

Hackers may utilise phishing emails, weak passwords, unpatched software, or vulnerable systems as entry points during this stage. Individuals and organisations need to focus on securing access points and regularly updating security measures to prevent unauthorised initial access by cybercriminals.
