Kaskus was created on November 6, 1999, by Indonesian students Andrew Darwis, Ronald Stephanus, Ken Dean Lawadinata, and Budi Dharmawan.

PC Magazine Indonesia named Kaskus in August 2005[1] as being the best site and largest online community and in 2006, as the choice of readers in 2006.

On May 23, 2006, the management was forced to change their .com domain to .us, due to the outbreak of the Brontok virus which was created to attack large sites in Indonesia.

For this purpose, Kaskus purchased eight Dell PowerEdge 2950 servers and operated them via a network of open IXP.

In March 2008, after convincing his cousin Andrew to expand and create a proper business out of Kaskus, Ken Dean Lawadinata came on board as partner and CEO.

This year Kaskus also went through some changes with Ken Dean Lawadinata after his 7 years of turnaround of Kaskus from a 1-man forum site to Indonesia's leading online forum, moved up to become the new Chairman of PT Darta Media Indonesia, with Martin Hartono assuming the day-to-day operation as the new CEO.

In September 2015, the forum's trading section (Forum Jual Beli) was rocked by an scam involving a long-running escrow service (referred by its users as rekening bersama) called Blackpanda, in which both sellers and buyers lost over Rp.

It was launched on November 6, 2009, on the 10th Anniversary Celebration of Kaskus at Poste, the east building, Kuningan, Jakarta.

Transactions through KasPay involve money transfers, which are aimed at enhancing security and reducing the risk of credit card fraud.
