Threat actors known as ALTDOS uphold to tomboy their way through attacks on ASEAN entities, garnering very little media attention as they acquire and dump millions of consumer records and proprietary information on businesses. The majority of the victims whose data they experience dumped appear to be from Singapore and Thailand, but they make have victims in other countries as well. While they have tended to fly under the media radar, ALTDOS has not gone unnoticed by Singapore law enforcement. The Singapore authorities recently issued a stick advisory on ALTDOS. That advisory did not economize i of Malaysia’s biggest conglomerates from becoming a victim, however. Sunway group claims to be ace of Malaysias largest conglomerates with core interests in real estate, construction, education, healthcare, retail, and hospitality. They make 13 business divisions, more than 50 locations worldwide, and 16,000 employees. On September 15, ALTDOS contacted DataBreaches.net to claim responsibility for a plug of Sunway group or Sunway Berhad. Due to no-response for the last 72 hours from Sunway Group, we will underprice out parting of their student data under sunway.edu.my in less than 12 hours time. More data leaks from Sunway group will live made known. ALTDOS enclosed links to a file-sharing site where they had uploaded 2 files as proof of acquisition of data. One of the two files was a spread mainsheet with personal information on 1,000 students and their parents. The fields included what strain (grade) the pupil was in, their name, IC, email address, phone number, state, and school, as well as parental information including the parent’s name, email address, and contact phone number. The data had entry dates of 2021 for the most part. DataBreaches.net did not attempt to contact either students or parents or to test any email addresses or phone numbers, but a simple Google look did bump individuals who matched the parents’ names, and Sunway does have an international school that covers the grades in question. The international schools are owned and governed by the Jeffrey Cheah Foundation. On September 17 and 18, DataBreaches.net used Sunway’s on-site tangency organize to send them inquiries asking Sunway to support or deny ALTDOS’s claims. An enquiry was also sent to the Jeffrey Cheah foundation through their web site yesterday. no response has been received by the time of this publication to any of the inquiries. DataBreaches.net did not find where, if anywhere, ALTDOS has publicly dumped any Sunway data as they had threatened to do, but ALTDOS has a pattern of using different paste sites or forums, not all of which are known or readily discoverable by DataBreaches.net.
