Depending On Hackers For the Information - NSA

In the latest article based on the Snowden documents, the Intercept is reporting that the NSA and GCHQ are piggy-backing on the work of hackers:

In some cases, the surveillance agencies are obtaining the content of emails by monitoring hackers as they breach email accounts, often without notifying the hacking victims of these breaches. "Hackers are stealing the emails of some of our targets...by collecting the hackers' 'take,' we...get access to the emails themselves," reads one top secret 2010 National Security Agency document.
