I recently noticed a series of small deposits made via Chaseâs mobile deposit feature. I didnât deposit this money (there were five deposits, all under $20). My guess is that an attacker wanted to see if anyone was monitoring the account. I called Chase to freeze my account, and theyâre âconducting an investigationâ as well.
Iâm not sure how this happened. My best guess is that it has something to do with a guest network in my apartment building that I sometimes connect to, and might have accidentally used to log into my Chase account. But Chase uses HTTPS, so shouldnât that not matter? I doubt itâs malware on any of my devices â I use Ubuntu and iOS exclusively, and donât install much third-party software on either. I donât have an information security background, so Iâm not sure about the situation. If thatâs not it, how might this have happened? My password for Chase isnât used for any of my other accounts. Itâs probably not an excellent one, but itâs also not terrible. Iâve never told anyone the password. How might this have happened? Is there anything I can do to learn more about how it happened? What should I do to prevent this from occuring in the future?
