Full Report
In an interview with Recorded Future News, Deibert explained the technical aspects of the Citizen Lab’s methods and how spyware companies continue to evolve to evade detection.
Analysis Summary
This summary focuses on the techniques and tools discussed by Ron Deibert of the Citizen Lab regarding the detection and analysis of commercial spyware, drawing heavily on their methodologies rather than detailing a single specific malware family or tool (though related commercial spyware like Pegasus is mentioned in the tags).
# Tool/Technique: Commercial Spyware Detection Methodologies (Citizen Lab Focus)
## Overview
The methodologies employed by Citizen Lab, led by Ron Deibert, focus on two primary directions to detect and diagnose infections by commercial spyware: analyzing the network infrastructure associated with spyware operations (C2 servers) and performing forensic analysis on victim devices. They leverage technical systems for evidence-based monitoring, similar to arms control verification models.
## Technical Details
- Type: Technique (Network Scanning, Forensic Analysis)
- Platform: Diverse (Mobile devices, Network infrastructure)
- Capabilities: Fingerprinting spyware C2 networks, reverse-engineering captured exploits/spyware, forensic extraction and analysis of infected device data.
- First Seen: Methodologies evolved over time, notably inspired by arms control monitoring concepts applied to the internet context established when Citizen Lab was founded.
## MITRE ATT&CK Mapping
Since the article discusses detection *methods* rather than specific offensive TTPs being executed, the mappings below reflect the offensive techniques these detection methods aim to identify.
- **TA0011 - Command and Control**
- T1071 - Application Layer Protocol
- T1071.001 - Web Protocols
- **TA0006 - Credential Access** (Often the objective of spyware)
- T1003 - OS Credential Dumping
- **TA0003 - Persistence** (Implicit, as spyware must maintain access)
- T1505 - Service Implanting
- **TA0010 - Exfiltration**
- T1041 - Exfiltration Over C2 Channel
## Functionality
### Core Capabilities
- **Network Fingerprinting:** Scanning the internet for computers/servers that respond in particular ways that match known characteristics of spyware command and control (C2) infrastructure.
- **Victim Forensics:** Performing detailed analysis on extracted data from infected phones to pinpoint the exact timing and specifics of a hack.
- **Proactive Discovery:** Identifying infrastructure implicated in espionage by monitoring C2 circuits.
### Advanced Features
- **Deep Packet Inspection Device Identification:** Identifying specific network hardware being misused, such as Sandvine (formerly Procera) Deep Packet Inspection (DPI) devices used to redirect web requests leading to an infection (e.g., the Eltantawy case).
- **Exploit/Spyware Insight:** Utilizing captured exploits and spyware from prior disclosures to understand how modern commercial tools beacon and communicate, aiding in signature creation and behavioral detection.
## Indicators of Compromise
*Note: The article discusses methodologies for *finding* IoCs rather than listing specific IoCs for one singular tool.*
- File Hashes: [Not explicitly listed, but forensic analysis aims to extract these.]
- File Names: [Not explicitly listed, but forensic analysis aims to extract these.]
- Registry Keys: [Not explicitly listed.]
- Network Indicators: [General mention of C2 servers/complex infrastructure used by spyware companies.]
- Behavioral Indicators: [Infection beaconing patterns, data extraction activities observed during forensic analysis.]
## Associated Threat Actors
The methodologies are used to investigate activity by various actors utilizing commercial spyware, including:
- Government clients of prominent spyware vendors (e.g., NSO Group clients).
- State actors (e.g., UAE mentioned in connection with Karma spyware).
- Entities involved in surveillance against journalists and political figures across multiple countries (Hungary, Greece, Spain, Poland, El Salvador, Thailand, etc.).
## Detection Methods
- **Signature-based detection:** Aided by reverse engineering captured malware samples.
- **Behavioral detection:** Analyzing anomalous network beaconing and specific data extraction patterns on victim devices.
- **Network Scanning:** Proactively querying internet resources to find devices responding as part of a C2 network.
## Mitigation Strategies
- **Due Diligence on Vendors:** Recognizing that contractual restrictions (like NSO’s proclaimed policy against targeting US numbers) are often "soft rules" easily circumvented by clients.
- **Preparedness:** Being prepared for the worst potential scenarios regarding government deployment of surveillance technologies against civil society.
- **Forensic Readiness:** Maintaining high confidence in forensic findings when confirming an infection.
## Related Tools/Techniques
- **Pegasus** (Mentioned in connection with past targeting allegations)
- **Karma Spyware** (Mentioned regarding UAE activity)
- **Sandvine/Procera DPI Devices** (Mentioned as infrastructure susceptible to misuse for infection delivery)
