A 419 scam, also known as an advance-fee fraud or Nigerian scam, involves soliciting a target through an email or letter. The sender, posing as a wealthy individual, government official, lottery winner, or business partner, claims they need assistance transferring a large amount of money. They promise the target a substantial sum in return for a minor fee or personal information.

This type of scam is called a 419 scam due to its prevalence in originating from Nigeria or involving Nigerian addresses.

They might also ask for personal and financial information, ostensibly to verify the recipient's identity or to facilitate the transfer of the prize.

Romance scams are a type of social engineering scam in which scammers use emotional manipulation to prey on individuals looking for love or companionship online.

They will then use various tactics to establish trust and emotional connection with their victim, including flattery, love bombing, and even sending gifts.

Once a strong emotional connection has been established, the scammer will start to ask for money, often for fake emergencies or unexpected expenses.

These emails often provide a phone number or email address to contact if you wish to dispute the charge or cancel your membership. However, when victims reach out, the scammers, pretending to be representatives of the service provider, admit that an error occurred and request the victim's financial information, such as credit card details, bank account numbers, or social security numbers, under the guise of completing the cancellation process. Their objective is to deceive individuals and obtain their sensitive personal and financial data.

Sextortion scam emails are a form of cyber extortion where the sender threatens to release explicit or compromising images or videos of the recipient unless they pay a ransom, usually demanded in cryptocurrency. The scam typically begins with the sender claiming they have accessed the recipient's computer or online accounts, often alleging that they have installed malware that allowed them to capture embarrassing or intimate footage. The emails are usually designed to invoke fear and urgency, pressuring the victim to comply before they can consider their options or seek help.

Job scam emails are deceptive tactics used by fraudsters who pose as legitimate employers to prey on job seekers.

The emails typically include attractive job descriptions and offer favorable employment terms to lure victims into the scam. Once engaged, the scammer may request personal information and ask for payments, alleging they are necessary for background checks, training materials, or special software required for the job.
