MalindoAir Data Breach (2019)

If you are a customer of MalindoAir, here’s what’s now in circulation.

In early 2019, the Malaysian airline Malindo Air suffered a data breach that exposed tens of millions of customer records. Containing 4.3M unique email addresses, the breach also exposed extensive personal information including names, dates of birth, genders, physical addresses, phone numbers and passport details. The data was later extensively shared on popular hacking forums.

Leaked data cannot be deleted from the internet — anyone claiming otherwise is lying. Broker listings can be removed. We do the second, and show you exactly what to fix from the first.

What to do now

Steps that match what this notice says was exposed

Every step below is free and you do it yourself, and none of it depends on MalindoAir.

Report the passport number. A compromised passport number can be reported to the US State Department, which will flag it. Replacing it is neither quick nor free, so report it before you need to travel.

One more, whatever was exposed: a breach notice is a favourite disguise for a phishing email. If a message about this arrives, do not use its links — go to the company’s site yourself, or call the number on your statement.

Were you a MalindoAir customer?

MalindoAir is one listing. Your email is probably in others.

4.3M accounts were exposed here. Check whether yours is one — and find every other leak tied to the same address, in about 15 seconds. No account, no card.
