It is no secret that there are a lot of scammers on the internet. Twitter, for example, is full of them, and now the scammers have gotten to a point in which they do not need to even use their time anymore as they can use bots.
A popular scam that has been plaguing Twitter these days is that fake bots pretending to be famous users are telling people that they are giving crypto away and the only thing that they are asking is for a small quantity of crypto to be sent to their address to prove that you are “serious”. As you might have imagined, this is a scam.
After months having this type of problem with bots, Twitter has finally decided to take these scambots seriously and to do something about it. One of the measures that the company has taken is to freeze the accounts of people who change their names to names of celebrities.
Say that you decide to change your name to “Elon Musk”, for instance. Now, your account will be frozen and you will have to provide a phone number and complete a CAPTCHA to prove that you are real.
CAPTCHA stands for Completely Automated Pubic Turing test to Computers and Humans Apart. It was developed at the end of the 90s and it is one of the main defenses used to prevent automated attacks.
One of the most popular CAPTCHAs is to use letters that can easily be detected by humans but not by machines and many sites use them. While the idea is very old, major companies like Facebook, Google and Twitter use it all the time and the level of accuracy is getting bigger.
However, now machine learning has started to be used as a way to break the CAPTCHAs and some people are starting to bypass them.
Jigsaw Puzzles To Defeat Bots In Seconds
To use a Binance account, users are normally required to solve a jigsaw puzzle made by the company. If they can move a piece of the jigsaw into the right place in under a minute, they get access. It they are not able to do it correctly, they have to do it again.
This new CAPTCHA test was created by a company called GEETEST, which is based in China and it a subsidiary of Wuhan Kaigi Network Technology Co. Ltd. Binance was one of the first clients of the company.
The main problem is that outdated CAPTCHAs can leave the community vulnerable to attacks because they can already be overcome with some ease. Because of this, Twitter could simply start to adopt the latest technologies instead of keep using the old ones.
Because of this, companies should invest in updated software to be able to actually be useful and reach their goals. Technology is evolving fast and the only way to actually be able to do it is by evolving defenses as well as the attacks.
