March 2009 Borking of PCL

Sometime in the middle of March 2009, Club Penguin decided to do something about PCL. They changed the way that passwords are encrypted and sent to the server, therefore rendering PCL useless. They had all of their sauce for this in one encrypted SWF file, sentry.swf. In late June 2009, Charles and RNA Inject successfully breached this encryption and fixed the Penguin Client Library.

July 2009 Release

After Charles and RNA Inject had fixed PCL in June, they immediately started rewriting PCL. On July 26th, 2009, they released the next version of PCL. It was based on PCL r-3, by Nick Stallman (Cheater). The main difference is that it was written in Object Oriented PHP, allowing it to have multiple connections to Club Penguin in one script. This release, instead of being called R-4, was called PCS, for Penguin Client System. Many people still call it Pickle.

Mailraep

Mailraep was the given to a bug in club penguins filtering, allowing any message to be passed on Club Penguin, without it being filtered. This technique was used against the Nachos.

September 15th Downtime

The password encryption mechanisms were changed again on September 15th 2009, but it was cracked again within minutes of the update. Unfortunately this coincided with website downtime, leading to confusion.

The Collective

The Collective was created using PCL.
