Chamelgang
ChamelGang is described in the provided content as a Chinese cyberespionage group, assessed by researchers as Chinese government-linked. Reporting from SentinelOne, Recorded Future, and TeamT5 says the group has repeatedly deployed ransomware and encryptors not only for financial gain, but also for disruption, distraction, misattribution, and removal of evidence. The content attributes 2024 campaigns involving ransomware and encryptors to ChamelGang and states that its motivations included financial gain, disruption, and evidence removal. Researchers also linked ChamelGang to 2022 attacks on the Presidency of Brazil and the All India Institute of Medical Sciences in India, both initially disclosed as ransomware incidents involving CatB ransomware; that attribution was based on technical overlaps in malware code with other tools used by the group. The content states ChamelGang had previously targeted a government in East Asia, an aviation organization in South Asia, and government and private organizations in the United States, Taiwan, and Japan. Across the cited reporting, ChamelGang is presented as an example of a Chinese espionage actor using ransomware as operational cover to obscure espionage, hinder investigation, and destroy evidence. No additional aliases or sub-groups beyond "chamelgang" are provided in the content.
