What is hacking?
Hacking is the act of compromising or manipulating a computing device or system by finding weaknesses to test or exploit. Hacking attacks are perpetrated for a variety of purposes and ideological reasons, such as terrorist financing, money laundering, and sanctions evasion. For example, the infamous Lazarus Group, which stole billions in cryptocurrency, is believed to be a North Korean hacking unit.

A recent example of "white hat" hacking is the $612 million hack of Poly Network, an interchain protocol. A few days after the heist, the white hat hacker announced the return of the funds and called himself an "eternal legend".
A recent "black-hat" hack was the $90 million hack of Japan’s Liquid exchange in which funds were stolen from warm wallets, the bridge between Internet-connected hot wallets and cold wallets offline. Hacking takes on particular importance in the study, development and exploitation of cryptocurrencies because the basic premise of blockchain is to help users abandon the traditional system and its assets.

Some of the most notable hacks in cryptocurrency history are Mt. Gox (2014), Coincheck (2018) and Bitfinex (2019). Hackers often use malware and viruses through phishing techniques to compromise security systems or force users to unwittingly expose their personal crypto credentials.
