ALTDOS hackers

ALTDOS hackers are a financially motivated cybercriminal group known for conducting network intrusions. They primarily employ brute force attacks and code injection techniques to gain unauthorized access. Once inside a target environment, they exfiltrate large volumes of data. The group then attempts to extort payment from the victim in exchange for not publishing the stolen information. If negotiations fail or payment is not received, ALTDOS has released portions of the compromised data publicly. The group explicitly states that its operations are not driven by political motives.

ALTDOS has indicated a focus on entities within the ASEAN region, describing its activities as part of broader regional targeting. A notable example occurred on 1 November 2020, when the group breached a Thai media conglomerate. During that incident, they reportedly exfiltrated hundreds of gigabytes of data from multiple subsidiaries. The stolen data included customer information such as names and ages. After demanding a ransom, the group claimed that negotiations broke down due to communication barriers. Consequently, ALTDOS proceeded to release the customer data to the public. The victim organization confirmed unauthorized access to some employee and customer data while asserting that financial records and identification documents remained secure. ALTDOS has maintained that its agenda is purely financially motivated and not politically aligned.
