A hacker managed to get into the PHP source code to install a backdoor.
At the end of March 2021, the team in charge of PHP’s cybersecurity observed two changes in its source code.
The cybersecurity team did an excellent job, preventing a gigantic catastrophe. PHP is a programming language used by nearly 80% of websites. Without the teams active vigilance, and all the work in maintaining the integrity of PHP, the problems would be unprecedented.
In any case, PHP has opened an investigation into the flaw, with the aim of ensuring that the hackers have not made any further modifications and to prevent the catastrophe from happening again.
