Hair of fire 2 of 5

SUMMARY: Hackers stole information from Twitter – one of over 4,100 data Breaches in 2022

Why do hackers want personal data, regardless if it is your complete profile or not?

  • Assemble data fragments from multiple sources
  • Identity theft

What happened:

According to Bleeping computer:

In January 2022, Twitter received a report through its bug bounty program that an API vulnerability allows an attacker to feed email addresses or phone numbers and get an associated Twitter ID for a registered account. As members’ phone numbers and email addresses are not meant to be public, this could pose a significant privacy risk for Twitter users who wish to post anonymously. By the time Twitter remediated the problem, a threat actor had already leveraged the API vulnerability to input millions of email addresses and phone numbers to create 5.4 million user profiles consisting of public and non-public data.

How many breaches? According to Cybersecurity Hub,

More than 4,100 publicly disclosed data breaches occurred in 2022 equating to approximately 22 billion records being exposed. Cyber security publication Security Magazine reported that the figures for 2022 are expected to exceed this figure by as much as five percent.
