I think I found what was going on, although the server OS was secured with a strong password, the postgress database was not, I forgot to change the default password and I guess a bot just scanned my db and tried the default password ! I’m dumb x)

It can’t be SQL injection as the client never really commands the database, that is to say that the client sends packets then the server processes these packets and asks the database but no SQL injection is possible as the information in the packet is already “parsed” by the server logic, no raw data is queried.

oh no, I was going to try digitalocean trusting their name in the game, but when I got asked for a passport scan and a selfie when all I wanted to do is learn docker with a couple of web apps to try, I canceled my account. the worst part is I gave my credit card info at the first step. and now when I see they’ve got hacked and data has leaked I’m genuinely worried about my credit card info.
