(Reuters) - A team of sophisticated hackers believed to be working for the Russian government won access to internal communications at the U.S. Department of Homeland Security, according to people familiar with the matter.

The breach was part of the campaign reported Sunday that penetrated the U.S. departments of Treasury and Commerce.

DHS is a massive bureaucracy responsible for border security, cybersecurity and most recently the secure distribution of the COVID-19 vaccine.
