Recently, PCGAMER and other sites have reported via battlefield developers and such that accounts have been compromised.
It happened to me recently. My battlefield account is linked to my origin and was exposed and I noticed FIFA purchased on my account.
I'd change passwords even if it hasnt affected you. This might be more applicable to those of the battlefield division
Also EA are funny
