Look for BreachForums Version 5’s own notice or letter: it should say what of yours was involved. Keep it.
Change your BreachForums Version 5 password, and the same password anywhere else you use it. Turn on two-step sign-in.
Expect scams that use your details: calls, texts or emails pretending to be BreachForums Version 5, your bank or the police. Never give codes or passwords, never approve a sign-in you did not start, never move money.
