Longhorn: Tools used by cyberespionage group linked to Vault 7:
Spying tools and operational protocols detailed in the recent Vault 7 leak have been used in cyberattacks against at least 40 targets in 16 different countries by a group Symantec calls Longhorn. Symantec has been protecting its customers from Longhorn’s tools for the past three years and has continued to track the group in order to learn more about its tools, tactics, and procedures.
The tools used by Longhorn closely follow development timelines and technical specifications laid out in documents disclosed by WikiLeaks. The Longhorn group shares some of the same cryptographic protocols specified in the Vault 7 documents, in addition to following leaked guidelines on tactics to avoid detection. Given the close similarities between the tools and techniques, there can be little doubt that Longhorn’s activities and the Vault 7 documents are the work of the same group.
