Deputy Dog

Deputy Dog is a threat actor group that conducts network intrusions against targeted organizations, with a suspected attribution to China. The group is also known as Tailgator Team or APT17 and has primarily targeted the U.S. government, international law firms, and information technology companies. In 2015, Deputy Dog quickly used a zero-day vulnerability (CVE-2015-5119) following the Hacking Team leak, demonstrating their agility and ability to pivot quickly in response to new opportunities. This incident highlights the group's proficiency in exploiting vulnerabilities and suggests a high level of technical expertise. Overall, Deputy Dog poses a significant threat to the security and confidentiality of targeted organizations' sensitive information. Their advanced tactics and techniques, coupled with their aggressive approach to network intrusion, make them a formidable adversary in the cybersecurity landscape. As such, it is essential for organizations to remain vigilant and implement robust security measures to protect against potential attacks from this threat actor group.
