Exclusive Scotiabank leaked online a trove of its internal source code, as well as some of its private login keys to backend systems, The Register can reveal.

Over the past 24 hours, the Canadian financial giant has torn down GitHub repositories, inadvertently left open to the public, that contained this sensitive information, after The Register raised the alarm. These repositories featured, among other things, software blueprints and access keys for a foreign exchange rate system, mobile application code, and login credentials for services and database instances: a potential gold mine of vulnerabilities for criminals and hackers to exploit.
