It turned out that personal information such as email addresses of about 230 million users of Twitter, a major American social media company, may have been leaked.
According to Bloomberg and others in the United States, the names and email addresses used to create Twitter accounts of about 230 million Twitter users, including politicians, journalists, and bankers, may have been leaked. Etc.
These personal information data are believed to have been extracted due to a software defect on Twitter.
Each media has pointed out that the leaked personal information is posted on a dark site for hackers on the Internet, and there is a risk of being misused for hijacking Twitter accounts.
Aron Gul, co-founder of Hudson Rock, an Israeli cybersecurity firm, was among the first to point out the issue, writing on his social media account: "This is one of the most serious data breaches I have ever seen." And so on.
The FTC (Federal Trade Commission), an American regulatory authority, has strengthened surveillance over Twitter's personal information management system, and since Elon Musk acquired it in October last year, many employees, including engineers, have been dismissed. In the midst of this, the focus is on what kind of measures the company will take in the future.
