H2: The Five Most Common Hacking Techniques

H3: Phishing

Definition

Phishing is a type of cyber attack that involves tricking individuals into divulging sensitive information, such as login credentials or financial information, by posing as a trustworthy entity. It is typically carried out through email, social media, or websites, and is often used to steal personal information or install malware on a victim’s device.

How it works

Phishing attacks usually begin with a message or link that appears to be from a legitimate source, such as a bank or online retailer. The message may contain a sense of urgency, such as a warning that the victim’s account will be closed if they do not immediately click on a provided link and enter their login credentials. The link often leads to a fake website that looks identical to the legitimate one, but is actually controlled by the attacker. The victim is then prompted to enter their login credentials, which are then captured by the attacker.

Examples

One example of a phishing attack is the “Nigerian Prince” scam, in which a victim is contacted by someone claiming to be a wealthy individual who needs help transferring a large sum of money. The victim is asked to provide their personal information, such as their social security number or bank account details, in order to facilitate the transfer.

Another example is the “CEO Fraud” scam, in which an attacker poses as a high-level executive or CEO of a company and requests that an employee transfer funds to a specific account. The employee may be asked to provide login credentials or other sensitive information in order to complete the transfer.

Prevention tips

To prevent falling victim to a phishing attack, individuals should be wary of messages or links that ask for personal information, and should always verify the authenticity of any requests before providing any sensitive information.
