Cybercrime Involving Hacking Of Cryptocurrency Exchanges
1. Introduction to Cybercrime in Cryptocurrency Exchanges
Cryptocurrency exchanges are digital platforms that allow users to buy, sell, or trade cryptocurrencies like Bitcoin, Ethereum, and others. Due to their high-value transactions and relatively weak regulatory oversight, exchanges are prime targets for hackers.
Types of cybercrime in cryptocurrency exchanges include:
Exchange Hacks: Direct attacks on the exchange to steal crypto assets.
Phishing & Social Engineering: Trick users into giving up login credentials or private keys.
Ransomware Demands: Locking exchange systems and demanding cryptocurrency as ransom.
Insider Fraud: Employees misappropriating funds.
Consequences:
Massive financial losses for users and exchanges.
Legal and regulatory scrutiny.
Damage to reputation and loss of trust in crypto markets.
Legal frameworks involved:
IT Act, 2000 (India): Cybercrime provisions.
Computer Fraud and Abuse Act (U.S.): Prohibits unauthorized access to computers.
Securities & Commodities Laws: For crypto as securities.
International cooperation via Interpol and Europol.
