Forensic browser cookie viewer2/18/2023 Sample screenshots of a sample virtual box accessed through TeamViewer, showcasing the inventory of anti-forensic tools/applications available at the disposal of potential cybercriminals: System settings can be set through sophisticated patching/hooking of legitimate applications to mimic any given set of preferences - including the pseudo-random generation of preferences - such as the following: By modifying the host’s hardware specifications, the service completely anonymizes its interaction with the Internet. This service empowers a potential cybercriminal with the necessary point’n’click capabilities to completely anonymize the virtual machine. We’ve been tracking an extremely sophisticated - in terms of its potential application when orchestrating fraudulent and malicious campaigns - TeamViewer-based managed service that offers virtual machines pre-loaded with a district set of anti-forensics tools, including many private versions. The very existence and utilization of these tactics successfully undermines the currently accepted techniques for attributing cybercrime campaigns to the correct parties. With digital forensics playing a crucial role when assessing cybercrime incidents, in the context of attribution, and ‘case-building’, it shouldn’t be surprising that, for years, sophisticated adversaries have been actively applying off-the-shelf anti-forensics tactics, techniques and procedures (TTPs). Nowadays, this set of tactics has evolved into a diversified mix of legitimate and purely malicious infrastructure that provides value-added services such as APIs supporting Socks4/Socks5 services, DIY real-time Socks4/Socks5 syndicating tools, and the development of hybrid based type of anonymous ‘solutions’. These services empower cybercriminals with the necessary ‘know-how’ to conceal their activities online, and there is a as clear attempt to standardize this ‘know-how’ through the distribution of commercial OPSEC training manuals. Throughout the years, the industry has witnessed active utilization of malware-infected hosts ( Socks4/Socks5) as anonymization ‘stepping stones’ and the use of cybercrime-friendly VPN providers, bypassing internationally accepted data retention regulations, as some of the primary anonymization tactics used by cybercriminals. Operational Security (OPSEC) has always been an inseparable part of the cybercrime ecosystem, especially in the context of preventing law enforcement agencies from tracking down the activities of fraudulent and malicious adversaries online.
