The Field Briefing #012 — October 26, 2026 From the Red Flag Cyber research desk

NEXT ISSUE — The desk is watching for Mirae Asset Life's follow-up: how many customers were affected, and exactly what information was taken. The company says both are still under investigation.

DEEP DIVE — Mirae Asset Life breach: customer personal and credit information confirmed leaked (CONFIRMED)

The Short Version: Mirae Asset Life said on October 26, 2026 that a breach of its customer insurance application system and parts of its website leaked customer personal and credit information. The company detected suspicious activity in its systems the previous day, Sunday, October 25, and confirmed early on Monday that personal and credit information had been leaked. How many customers are affected, and exactly what was taken, are still under investigation.

What to do now: - Treat unexpected calls, texts or emails that claim to be from Mirae Asset Life — especially any that ask you to hand over more personal or financial information, or a verification code — as unproven until you have checked them through a channel you open yourself, such as the company's official website or a number you already have. - Keep an eye on your bank and credit activity for loan or credit applications and transactions you do not recognise, and report anything unfamiliar to the provider promptly. - Do not use links or phone numbers supplied inside a suspicious message to do the checking.

RED FLAG OF THE WEEK — Changing your password does not remove an inbox rule someone else created. Rules live on the mailbox, not on your password, so a hidden rule keeps forwarding or hiding your mail until you delete it. Check Rules and Forwarding in Outlook on the web, and the Forwarding tab and Filters and Blocked Addresses in Gmail — then delete what you did not create.
