Apart from Atwal, who won the title in 2003 and 2008, PGA member KJ Choi will be headlining the field of players in the 156-strong line up competing for top honours in the March 4 to 7 event.
Joining Choi in a clash of the champions from the various tours are the familiar faces of two-time Maybank Malaysian Open Thongchai Jaidee and Asian Tour's Prayad Marksaeng.
European Tour's Darren Clarke and Chris Wood, together with Japan's Shingo Katayama and PGA member Daniel Chopra, round off the line up of the event.
Atwal, who was off course most of last year due to shoulder injuries, won his second Maybank Malaysian Open title in 2008 overcoming then defending champion Peter Hedblom in a play-off.
Atwal, the first Indian player to secure membership of the US PGA Tour, will have to slog it out this season to retain his card due to the lengthy injury layoffs last year.
Defending champion Anthony Kang, who notched up a thrilling one stroke victory at last year's Maybank Malaysian Open, will be back this year.
Kang would be hoping to defend his title at the Kuala Lumpur Golf and Country Club and make an impressive start to the new season.
The 2009 Asian Tour Order of Merit champion Thongchai Jaidee will also be returning to the event, which he has won twice.
Apart from an attractive purse of USD two million, the event also offers vital Race to Dubai points for those from Europe and a two year exemption on the European Tour for the winner.
