What happened
In October 2025, data stolen from the Salesforce instances of multiple companies by a hacking group calling itself "Scattered LAPSUS$ Hunters" was publicly released. Among the affected organisations was Vietnam Airlines, which had 7.3M unique customer email addresses exposed following a breach of its Salesforce environment in June of that year. The compromised data also included names, phone numbers, dates of birth, and loyalty program membership numbers.

Remember: a breach can’t be “un-leaked” — once a database is out, it exists in countless copies. The goal is to make the leaked data useless: change what can be changed, lock down what can’t, and remove what has been republished.
