dezetat is an alias associated with the advertisement of an alleged stolen database purportedly taken from Malaysia's Inland Revenue Board (LHDN/IRBM) MyTax portal. The actor was observed offering the claimed dataset for sale and presenting it as a large-scale taxpayer data breach affecting Malaysia. The available information supports characterization of dezetat as a financially motivated data seller engaged in monetizing allegedly exfiltrated sensitive information. The reported activity centers on the sale of purported taxpayer records rather than a fully documented intrusion lifecycle. High-confidence facts indicate the actor advertised data allegedly originating from a Malaysian government tax platform and sought payment for access to it. This behavior is consistent with exfiltration-linked criminal monetization and data-theft extortion ecosystems, although the underlying breach claim itself remained unverified at the time of reporting. No corroborated information is available on additional aliases, sub-groups, malware usage, intrusion methods, or broader operational history.
