The Hack

The HackTwitter accounts suspected of Bitcoin scam hacked.. (via

On Jul 15, 2020, reportedly 130 high-profile Twitter accounts, both verified and unverified ones such as Elon Musk, Joe Biden, Jeff Bezos, Michael Bloomberg, Kim Kardashian West và Bill Gates were compromised by outside parties to promote a bitcoin scam.

Within minutes from the initial tweets, 12 bitcoins from over 320 transactions had already taken place on one of the wallet addresses, and bitcoin to a value of more than US$118,000.

Hackers orchestrated a series of social engineering attacks against Twitter staff that had access to the internal administrative tools that Twitter can use to recover and reset accounts.

Three individuals were arrested by authorities on Jul 31, 2020 and charged with wire fraud, money laundering, identity theft, and unauthorized computer access related to the scam.

As the novel coronavirus spread globally, leaders hunkered down at home, Canadian Prime Minister Justin Trudeau who went into self-isolation after his wife tested positive for COVID-19.

Original Idea

original ideaoriginal idea

Jack Dorsey (@Jack), then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group. The original project code name for the service was twttr, inspired by Flickr and the five-character length of American SMS shortcodes.

The decision was also partly because the domain was already in use, and it was six months after the launch of “twttr” that the crew purchased the domain and changed the name of the service to Twitter.

The developers initially considered "10958" as a short code, but later changed it to "40404" for "ease of use and memorability".

On Mar 21, 2006, when Jack Dorsey published the first Twitter message: "just setting up my twttr", has sold his first-ever tweet for more than $2.9M, donating the money to a charity battling Covid-19 in Africa.

On Twitter, a word, phrase, or topic that is mentioned at a greater rate than others is said to be a "trending topic" or simply a "trend".

Trending topics are those topics being discussed more than others.

Trending topics are accompanied by hashtags that allow to easily find all the tweets and conversations by users around that topic. These topics help Twitter and its users to understand what is happening in the world and what people's opinions are about it.


Notifications are updates and information, alerting you to what's happening on Twitter.

You can view your notifications in two ways: All shows you notifications for account activity like new followers, Retweets, mentions, and likes. Mentions show you notifications only for Tweets that mention your username.


Bookmarks are a useful way to save information, the bookmarking is done privately, and the data isn’t shared with anyone. Bookmarking tweets on Twitter lets you keep them for later so you can comment or review them at a more convenient time. When you bookmark a tweet, it shows up in the Twitter Bookmarks section.

Twitter Moments is a collection of your tweets or other users that you can collect on your profile. With Twitter Moments, you’ll create interesting Twitter stories that you can’t do on the app’s timeline.

Promoted Tweets are tweets that advertisers put money behind to reach a wider audience or spark more engagement with existing followers.

Twitter Topics is a Twitter setting that allows users to select and follow trends they're interested in from a list of Topics. Once a user follows a Topic, more news and tweets related to it will start showing up in their regular Twitter feed.
