Biggest Crypto hacks and the ways to stay protected


Cryptocurrencies have been around for more than a decade. Frequently, the facts of the hack are undisclosed. It’s easy to find whoever was attacked and when it happened, as well as how much revenue was stolen, but the «how» remains unclear. Let us just patch in the blanks and talk about how such hacks work — not to teach, but to avoid it from happening again.

Some of the biggest crypto hacks are-

  • The conventional crypto exchange hack involves phishing and malware-

Clients’ cryptocurrencies and regular money are stored in traditional bank accounts by crypto exchanges. Getting engaged with regular currency is perilous for hackers; to get off with stolen wealth, they’d have to cash it swiftly before the bank could block the accounts. That is why most hackers prefer cryptocurrencies.

The hackers first gathered a list of workers and researched their topics of interest, and then sent fraudulent emails with malware contents to people they thought were the most trustworthy. They then acquired their path around the organization, including how much the accountants spoke with the director, what they emailed one another, the private network’s design, and where and how the crypto wallets were housed. This stage can take a long time, but it finally takes the fraudsters to an employee’s machine with vital access privileges.

Possessing operator rights means the hackers can send cryptocurrency if the exchange’s automated system is designed to do so.

  • Theft of a secret key: Spell Check fails-

The secret key is required to spend cryptocurrency. The user’s balance is stored in the blockchain, and the key is what is maintained in crypto wallets.

The key is stored up in a seed phrase made up of 12 small terms for ease of use. The hack developed because, currently, apps are frequently constructed from elements, including those from third-party programmers, rather than being created from scratch. The seed word was only sent to Google and was protected, according to the developers. And Google gave them an error message. Nonetheless, the victim is certain that the burglary was caused by this loophole.
