In the ever-evolving landscape of encrypted messaging, criminal networks are shifting their operations to platforms like Signal, known for its robust privacy features. For law enforcement and OSINT professionals, this poses a growing challenge: How do we stay ahead of the curve when investigating secure platforms like Signal?
Signal’s lack of a public API and its heavily encrypted databases limit traditional research capabilities. However, with the right tools and methods, analysts can still extract, process, and analyze Signal data to uncover critical insights. Here’s how Paliscope Explore empowers investigators to address these challenges efficiently.

However, with the right tools and methods, analysts can still extract, process, and analyze Signal data to uncover critical insights. Here’s how Paliscope Explore empowers investigators to address these challenges efficiently.
With many Telegram users migrating to Signal, including criminal organizations, understanding Signal’s ecosystem is crucial. Unlike Telegram, Signal doesn’t offer public group indexes or extensive metadata, making investigations more complex. Analysts must adopt innovative methods to extract and analyze Signal data to adapt to this new threat landscape.
Signal’s robust encryption and lack of a public API pose significant hurdles for investigators aiming to access and analyze its data. However, with the right tools and technical expertise, extracting Signal data becomes manageable. Below are two primary methods investigators use, along with their unique advantages and challenges.
1. The Desktop Method: Extracting Encrypted Databases
Signal stores its data in encrypted SQLite databases on devices, which must be decrypted before analysis. Using tools like SQLCipher, investigators can gain access to these databases with proper permissions and processes.
Recent updates to Signal have encrypted the decryption key itself, adding a new layer of complexity. Investigators now need additional tools, such as GitHub’s Sigtop repository, to decrypt the key before accessing the database.
The desktop method provides access to a comprehensive snapshot of the device’s Signal activity, including messages, user data, and timestamps.
2. The Android Method: Exporting Backup Data
For Android devices, Signal offers an option to create encrypted backups of chat data. This method provides a streamlined path to data extraction, particularly for forensic experts familiar with Python-based decryption scripts.
The backup password is essential for decryption, so failing to save it renders the data inaccessible. Additionally, iOS devices and advanced privacy-focused Android builds like GrapheneOS may complicate or prevent data extraction.
This method is straightforward for devices with backups enabled and provides investigators with a database tailored for further analysis in Explore.
3. Beyond Devices: Using Invite Links and Metadata
While the above methods require direct device access, investigators can complement their efforts by leveraging OSINT techniques:
This approach doesn’t access encrypted messages but helps establish a broader context for investigations.
After successfully decrypting Signal data, importing it into Paliscope Explore transforms raw data into searchable and actionable intelligence. Explore automatically indexes data, so investigators can:
With Explore, the process doesn’t end with extraction – it becomes the foundation for effective analysis and case building.
Once Signal data is decrypted and imported, Paliscope Explore enables investigators to transform raw data into actionable insights. Its comprehensive set of tools and AI-powered capabilities streamline the process, making it easier to uncover critical details hidden within large datasets. Here’s how:
1. Cross-platform data correlation
Signal investigations rarely occur in isolation. Paliscope Explore supports importing data from multiple sources, such as Telegram, WhatsApp, and email archives, enabling investigators to correlate data across platforms. This feature is invaluable for identifying connections between suspects, platforms, and activities.
Example: A search for a username in Signal might reveal the same user’s activity on Telegram, complete with overlapping timestamps and shared content.
2. Advanced search and indexing
Explore functions as a customizable search engine for your imported data. By indexing text, images, audio, video, and metadata, the tool allows users to:
3. Pattern recognition and visualization
With built-in tools for pattern recognition, analysts can quickly identify suspicious activity trends, recurring user interactions, and content clusters.
Example: Explore might highlight repeated communication patterns between two users before significant events, helping investigators establish timelines or motives.
4. AI-Assisted translation and analysis
Signal conversations often span multiple languages, especially in cross-border criminal networks. Explore’s AI-powered translation allows investigators to understand foreign-language chats instantly. This is especially useful when analyzing international trafficking, smuggling, or organized crime networks.
Enriching data with OSINT Industries
Paliscope Explore integrates seamlessly with OSINT Industries, enabling direct lookups for usernames, phone numbers, or email addresses. Investigators can enrich Signal data by:
6. Visualization of relationships
Explore offers visualization tools that map relationships between users, messages, and shared content. These visualizations help investigators spot hidden connections and create overviews of the investigation.
Example: A visual map might show how a single Signal group links multiple smaller trafficking rings, highlighting the hidden contacts or communication paths..
7. Cross-referencing chat data with other data
Explore allows users to integrate Signal chat data with other types of data, such as forums, messages or mobile devices. Investigators can build stronger cases by:
