What is phishing? How does phishing work?

Phishing is a form of scam or attack that involves tricking the victim into sharing personal information or taking an action online. The intent of the attack is to obtain the user’s system credentials, financial information, or other sensitive information to be used for their benefit. These attacks can range from fairly simple to complex cyber security issues.

Generally, the scammer disguises as a trusted entity from a reputed source to entice the victim to take an action using emails or other forms of communication. Phishing emails are commonly used to distribute vicious links or attachments that can perform numerous functions such as extracting account information and login credentials and even installing malware on the victim’s system or directing them to cloned websites.

Spear phishing – This involves personalized targeting of high-profile account holders by the attacker by sending email messages to specifically targeted victims. The scammers gather or buy information about the target victim and mount their scam. This is one of the most effective forms of phishing resulting in about 90% of the attacks.

Clone phishing – This phishing method is one of the most difficult to detect. As the name sounds, scammers replicate an identical version of a recently received email and re-send it from a seemingly credible source, thus tricking the victim to take action. Although the message of the email could remain the same, links and attachments are replaced with malicious ones and upon clicking them they are directed to fake websites or infected attachments.

Whaling attacks – In plain terms, whaling is targeting the ‘big fish’ or senior executives of a company with the goal of extracting highly sensitive corporate data. The targets are generally high-ranking offices such as CEO, CFO and other high-level executives with access to highly sensitive data. After considerable profiling of the target, a well-timed attack is launched by the attackers to steal login credentials.

An example is the attack on Sydney hedge fund Levitas Capital to the tune of $8.7 million in November 2020.

Pop-up / scareware phishing – Here pop-up ads are used to trick users into installing malware on their system. They generally use scare tactics to prompt users to act fast to address an alleged cybersecurity concern. This is an effective way to gain access to the victim’s computer or steal credit card information. Some common pop-up techniques are – fake antivirus scams, clickjacking, virus removal scams, tech support scams, in-session pop-ups.

Link manipulation – Also known as URL hiding, this is used in different ways. Malicious URL links are created mimicking legitimate websites and unsuspected victims are directed to these malicious websites on clicking on these links.

Vishing – Also known as voice phishing, phone calls are used to make attacks. Attackers use automated voice messages that seem to be from legitimate institutions such as government entities or financial institutions that are communicated to individuals enticing them to provide their credit card credentials or Social security number. Generally, scammers entice victims to share personal information to claim rewards.

Smishing – SMS phishing or smishing is similar to email phishing and vishing. Here text messages that contain malicious links are sent to victims from what seems like legitimate sources. These links can be disguised in any form such as offers, chances to win something, or even discount coupons.

Social medial phishing – Social networking sites like Instagram, Twitter, Facebook, and LinkedIn are used by attackers to lure victims into clicking on malicious links. Attackers create fake accounts of individuals or businesses to prey on their victims.
