Cybersecurity researchers have discovered a new PHP-based backdoor called Glutton that has been put to use in cyber attacks targeting China, the United States, Cambodia, Pakistan, and South Africa. QiAnXin XLab, which discovered the malicious activity in late April 2024, attributed the previously unknown malware with moderate confidence to the prolific Chinese nation-state group tracked Winnti (aka APT41). "Interestingly, our investigation revealed that Glutton's creators deliberately targeted systems within the cybercrime market," the company said . "By poisoning operations, they aimed to turn the tools of cybercriminals against them – a classic 'no honor among thieves' scenario." Glutton is designed to harvest sensitive system information, drop an ELF backdoor component, and perform code injection against popular PHP frameworks like Baota (BT), ThinkPHP, Yii, and Laravel. The ELF malware also shares "near-complete similarity" with a know...
