The cryptocurrency ecosystem underwent a turbulent year in 2022. Criticism inside and outside of the crypto industry was fueled following the collapse of FTX, Celsius, Three Arrows Capital and the Terra ecosystem. A number of losses have been recorded from these events. Blockchain analytics firm Chainalysis released a report in December of last year, which noted that the depegging of Terra’s stablecoin, Terra USD Classic (USTC), saw weekly-realized losses peak at $20.5 billion. Findings further show that the subsequent collapse of Three Arrows Capital and Celsius in June 2022 saw weekly-realized losses reach $33 billion. While these events may have resulted in a loss of trust within the crypto ecosystem, it’s important to point out that blockchain technology and cryptocurrency have n...
200 million Twitter users’ private information, including their email addresses, was put for sale after a breach exposed 400M users’ private information in the last week of December 2022.

Password management service LastPass was hacked in August 2022, and the attacker stole users’ encrypted passwords, according to a Dec. 23 statement from the company. This means that the attacker may be able to crack some website passwords of LastPass users through brute force guessing.

Cryptocurrency exchange Gemini appears to have suffered a data breach on or before Dec. 13. According to documents obtained by Cointelegraph, hackers gained access to 5,701,649 lines of information pertaining to customers’ account numbers, email addresses and partial phone numbers. In the case of the latter, hackers apparently did not gain access to the full phone numbers, as certain numeric digits were obfuscated. The leaked database did not include sensitive personal information such as names, addresses and other Know Your Customer information. In addition, some emails were repeated in the document; thus, the number of customers affected is likely lower than the total rows of information. Gemini currently has 13 million active users. Security breaches in the Web3 industry, even if mild i...

As a result, the lawyers claimed that FTX employees and counsel prevented authorities from getting critical financial information. The database in question is reportedly stored on Amazon Web Se...
The crypto market slump doesn’t mean interest in crypto is also down.

While it was in second for overall searches, Turkey came in first place ...
