Malaysia sites hacked after blunder over Indonesian flag

Indonesian hackers have claimed to have attacked several Malaysian websites, following a blunder which saw the Indonesian flag printed upside down in a regional sports event's guidebook.

The mistake prompted fury in Indonesia over the weekend and President Joko Widodo demanded an official apology.

The book was printed for the Southeast Asian Games, which are being held in Kuala Lumpur.

Malaysian organisers and officials have apologised profusely.

The affected websites display a message in red and white - Indonesia's flag colours - which says: "My national flag is not a toy!"

At least 27 websites were affected, and were mostly for private businesses, according to Indonesian and Malaysian news outlets.
