The Telegram account of Foreign Minister Saifuddin Abdullah was hacked last night, just hours after the personal Telegram account of the prime minister was hit.
Saifuddin, who announced the matter on Twitter, said his name and picture on the application had also been abused.
"Anyone who receives a message from my Telegram should ignore it and report the matter to the authorities," he added.
Also yesterday, Ismail Sabri Yaakob said his Telegram account had been hacked by irresponsible parties and asked members of the public to ignore any messages from the account.
The Prime Minister's Office (PMO) said today that Ismail had lodged a police report over the hacks of his personal Telegram and Signal accounts.
The prime minister has also filed a report with the Malaysian Communications and Multimedia Commission.
The PMO said it believed the accounts were used for fraudulent criminal activities.
"Any individual who receives a message from the accounts should ignore it as it is a fake message from an individual impersonating the prime minister," it said.
