Step 1: Understanding the Concept:
The question describes a cybercrime that relies heavily on social engineering, where a scammer builds trust with a victim over a period of time before convincing them to invest money in a fraudulent scheme.
Step 2: Detailed Explanation:
Let's analyze the options:
(A) Worm hole: This is a concept from theoretical physics, not cybercrime.
(B) Pig Slaughter scam (or Pig Butchering scam): This is the correct answer. The name comes from the practice of "fattening up the pig before slaughter." In this long-con scam, the criminal develops a relationship (often romantic) with the victim over weeks or months, building a high level of trust. Once trust is established, the scammer introduces a supposedly lucrative investment opportunity (usually in cryptocurrency), convinces the victim to invest, and then disappears with the money. This method relies entirely on the victim believing in the offender.
(C) Web site attack: This is a broad term for an attack on a website and doesn't necessarily involve building personal trust with a victim.
(D) Virus attack: This is a technical attack where malicious software infects a system. It doesn't rely on the victim's belief or trust in the offender in the way described.
Step 3: Final Answer:
The 'Pig Slaughter scam' is a specific type of cybercrime that involves a long-term trust-building exercise before the victim is manipulated into parting with their money.
