Investigation Uncovers Digital Evidence
In the ongoing investigation of the car blast near Delhi’s Red Fort, security agencies have discovered a significant digital lead. Reports indicate that three doctors—Dr. Umar Un Nabi, Dr. Mujammil Ganai, and Dr. Shaheen Shahid—were engaged in secret communications via the Swiss messaging app Threema. These individuals are reportedly associated with Al-Falah University in Faridabad.
Challenges Posed by High-Level Encryption
Investigators have noted that Threema’s advanced encryption and anonymity features have complicated the inquiry. Notably, the app does not require a mobile number or email; instead, it operates through a random ID, allowing the suspects to evade detection by security agencies for an extended period.
Creation of a Private Threema Server
Sources suggest that the suspects established their own private Threema server, which facilitated the sharing of locations, files, maps, and plans related to the blast. The app’s end-to-end encryption, policy of not storing metadata, and the ability to delete chats on both ends have made it nearly impossible for forensic teams to trace any communications or data.
Agencies Investigate Server Location
Authorities are now attempting to determine whether this private server was located in India or abroad and whether additional individuals were involved in this network. It is important to note that Threema has been banned in India since May 2023, following the government’s restrictions under Section 69A of the IT Act, which targeted several high-encryption apps due to their use by Pakistan-based groups for propaganda and networking within India.
Suspected Use of VPNs to Circumvent Ban
Despite the ban, agencies suspect that the accused may have utilized VPNs to bypass restrictions. Their travels abroad, particularly to Turkey and the UAE, likely made it easier for them to use the app. Additionally, Threema’s payment system complicates the investigation further, as purchases can be made by sending cash to Switzerland or via Bitcoin, leaving no digital trace.
Emerging Challenges in Counter-Terrorism
Experts believe this case highlights how terrorist organizations are increasingly leveraging technology to conceal their networks and activities. Forensic teams are diligently working to unravel layers of digital data, indicating that the fight against terrorism will face new challenges in the future.
