Matt Cutt har nogle gode råd i “Securing your Google Account after a possible hack“. De er få og simple men dækker et bredt område, som f.eks.
Also check for weird forwarding rules. If hackers get into your Gmail, sometimes they’ll create a rule that forwards all your email to them. To check your filtering rules, in Gmail click on the gear icon in the top right, then select Settings from the drop down. Click on the link for “Filters” and just check whether there’s any rules that look suspicious to you.
