Overview
Ghostwriter also known as UNC1151 is a hacker group allegedly originating from Belarus. According to the cybersecurity firm Mandiant, the group has spread disinformation critical of NATO since at least 2016.
History
The name Ghostwriter comes from the group's first attacks, whereby they would steal credentials of journalists or publishers and publish fake articles using those credentials. Hence, the group effectively became unwanted ghostwriters for those with stolen credentials. UNC1151 is an internal company name by Mandiant given to uncategorized groups of "cyber intrusion activity."
The European Union has blamed this group for hacking German government officials.
EU's foreign policy chef Josep Borrell has threatened Russia for sanctions.
