What happened
In October 2017, the Malaysian website lowyat.net ran a story on a massive set of breached data affecting millions of Malaysians after someone posted it for sale on their forums. The data spanned multiple separate breaches including the JobStreet jobs website which contained almost 4 million unique email addresses. The dates in the breach indicate the incident occurred in March 2012. The data later appeared freely downloadable on a Tor hidden service and contained extensive information on job seekers including names, genders, birth dates, phone numbers, physical addresses and passwords.

What was exposed
Dates of birth: Your full birth date, day, month and year, collected at signup for age checks, identity verification, insurance quotes, birthday offers or government services.
Email addresses: The email address you used to register or log in. It is the most common field in breaches because it doubles as your username on most sites.
Genders: The gender or sex recorded on your profile, usually picked from a list at signup, sometimes with a title such as Mr or Ms or a gender identity option beyond male and female.
Geographic locations: A general location recorded on your account, such as a country, state, city, postcode or region, either typed in by you or estimated from your IP address.
Government issued IDs: Numbers or images of official identity documents, such as passports, national identity cards, Social Security numbers, Medicare cards, tax file numbers, residence permits and voter cards.
Marital statuses: Your relationship status, such as single, married, de facto, separated, divorced or widowed, collected by insurers, lenders, government forms, dating apps and marketing surveys.
Names: Your first name, surname and sometimes middle name or initials, as you gave them when you signed up. It appears in almost every breach because nearly every account asks for it.
Nationalities: The country of citizenship recorded against your account, collected by airlines, travel sites, visa services, banks, employers and some dating apps.
Passwords: The secret you use to sign in, stored by the breached service either in plain text, in a scrambled form called a hash, or encrypted. How it was stored decides how quickly it can be recovered.
Phone numbers: Your mobile or landline number, collected at signup for contact, delivery updates, marketing and two-factor codes.
Physical addresses: Your residential, postal, billing or delivery address, stored by retailers, utilities, banks, government services and almost any company that sends you something.
Usernames: The handle or login name you chose for an account, which may be public on forums, games and social platforms or used privately to sign in.
