Since 2022, Trend Micro researchers have been investigating numerous targeted attacks in the Asia-Pacific region that used the same ELF backdoor.

The researchers suspect it is being used by Chinese-speaking groups engaged in either espionage or cybercrime. We dubbed this formerly undocumented malware as “Noodle RAT.” Noodle RAT, also known as ANGRYREBEL or Nood RAT, is a relatively simple backdoor confirmed to have both Windows (Win.NOODLERAT) and Linux (Linux.NOODLERAT) versions.
