Twitter, whose internal systems were breached about two weeks ago, said on Thursday the incident targeted a small number of employees through a phone "spear-phishing" attack.

The US microblogging site said the hackers targeted about 130 accounts, tweeted from 45, accessed inbox of 36, and were able to download Twitter data from seven.

Attackers also targeted specific employees who had access to account support tools, Twitter said, adding that it restricted access to its internal tools and systems ever since the incident occurred.

Twitter Says Hackers Likely Saw Direct Messages of 36 Accounts

Hackers had accessed Twitter's internal systems on July 15 to hijack some of the platform's top voices including US presidential candidate Joe Biden, reality TV star Kim Kardashian, former US President Barack Obama and billionaire Elon Musk and used them to solicit digital currency.

Publicly available blockchain records show the apparent scammers received more than $100,000 (roughly Rs. 74,72,500) worth of cryptocurrency.

The "spear-phishing" technique is a practice of sending emails ostensibly from a known or trusted sender in order to induce targeted individuals to reveal confidential information.

Government Issues Notice to Twitter After Recent Hack

Reuters reported last week that more than a thousand Twitter employees and contractors as of earlier this year had access to internal tools that could change user account settings and hand control to others, making it hard to defend against the hacking.
