At the present time, supporter tallies remain at 72.6 million for PewDiePie and 72.5 for T-Series.
With respect to the specialized side of the hack, this wasn’t complicated in any way, nor was it unique.

The hack works by utilizing automated scripts to send print messages to printers that have IPP (Internet Printing Protocol) ports, LPD (Line Printer Daemon) ports, and port 9100 remaining open over the Internet.
@TheHackerGiraffe said in a Reddit AMA that he hacked just 50,000 printers, yet he could have effectively driven his message to more than 800,000 that are as of now exposed online presently.
To be successful, the programmer said that he utilized an apparatus called the Printer Exploitation Toolkit (or PRET), which was released in January 2017, when its creators published it together with an examination paper specifying six vulnerabilities in more than 20 network printers.
