Sydney-based software architect Troy Hunt has expanded his “Have I Been Pwned” tool to find out if your data has been leaked. The tool uses a Twitter feed called Dump Monitor, which monitors posts on Pastebin and other sites. It collects email addresses from the pastes and stores them in Hunt’s breach database. Users can sign up for alerts that are sent when their email address shows up in a paste. The service is free unlike those offered by companies that specialize in monitoring underground forums for stolen data.”]
