What type of data was NOT included in the leaked sample data from the cyberattack on PERKESO?

Question

BlackTom AI · Accepted Answer

The question asks which type of data was NOT included in the leaked sample data from the cyberattack on PERKESO. 
Option a: 'Driver's license numbers, date of birth, marital status, and educational background' — This set comprises personal identifiers and demographic details. While these kinds of data could plausibly appear in some breaches, the option asserts they were not included, which would be inconsistent if any such data appeared in the leak. Without the leak's specifics, we treat this as a possible but not definitive exclusion.
Option b: 'Full names, IC number, phone number, salaries, business name and blood type' — This group contains identifying information and some sensitive details like salaries and blood type. If these were present in the leak, the option would be incorrect about their absence. As with option a, the statement’s truth depends on the actual leak contents, so this remains a speculative candidate for not being included.
Option c: 'Credit card numbers, social security numbers, email addresses, and passwords' — This collection includes highly sensitive financial, government-issued identification, and credential data. In many breaches, such data are the ones most sought after, and their absence in a leaked sample would be notable. The option directly asserts these were not included in the leaked sample. Given the prompt and typical leak reporting, this option is consistent with a scenario where such highly sensitive credential data were not exposed in the sample, making it a strong candidate for the correct answer if the leak omitted these fields.
Option d: 'Home addresses, passport numbers, employment history, and medical records' — This set covers various personal records and highly sensitive information. If any of these types appeared in the leak, the option would be inaccurate about their absence; if none appeared, it could also be plausible. However, without confirmation, this option remains a plausible but uncertain statement.
Overall, to determine which option is truly not included, one would compare each option to the actual leaked sample contents. The option that asserts the exact data types not present in the sample would be the correct match to the leak report. In many real-world leak reports, highly sensitive financial and credential data (credit card numbers, SSNs, passwords) are precisely the types the sample might avoid including due to encryption, redaction, or protection practices, which makes option c a plausible fit for the intended answer.
