This guide emphasizes minimizing digital traces for protesters through practical smartphone security advice. It recommends using a secondary, "burner" phone dedicated to protests, ideally a basic model without internet connectivity. If using a primary smartphone, strong passcodes/biometrics, full-disk encryption, and up-to-date software are crucial. Minimizing data collection involves disabling location services, microphone access for unnecessary apps, and using privacy-respecting alternatives to default apps like Signal for messaging and a privacy-focused browser. During protests, enabling airplane mode or using Faraday bags is advised. The guide also covers digital threat models, stressing the importance of awareness and preparedness for potential surveillance and data breaches.
This comprehensive guide, entitled "The Protester's Guide to Smartphone Security," offers an extensive exploration of digital security practices specifically tailored for individuals engaging in protests or activism. Recognizing the heightened risks protesters face regarding surveillance and data compromise, the guide meticulously outlines numerous strategies for mitigating these threats. It begins by emphasizing the critical importance of threat modeling, urging readers to carefully assess their specific situation and potential adversaries, including law enforcement, corporate entities, or even malicious individuals. This individualized approach allows protesters to tailor their security measures to the unique challenges they may encounter.
The guide subsequently delves into a detailed examination of various technical aspects of smartphone security. A significant portion is dedicated to the selection of a mobile operating system, highlighting the enhanced privacy features offered by GrapheneOS and CalyxOS, while also acknowledging the relative strengths and weaknesses of iOS. It further underscores the significance of employing strong passcodes and enabling full-disk encryption to safeguard against unauthorized access to sensitive data.
The document then proceeds to explore secure communication methods, recommending the utilization of end-to-end encrypted messaging applications such as Signal. It expounds upon the benefits of utilizing a VPN for concealing one's IP address and encrypting internet traffic, thereby hindering surveillance efforts. Furthermore, the guide stresses the importance of disabling location services and limiting app permissions to minimize data collection by third-party applications.
Beyond these technical considerations, the guide also emphasizes the practical aspects of maintaining security during protests. It advises protesters to disable biometric authentication methods, such as fingerprint or facial recognition, which could be compelled by law enforcement. It also recommends carrying a secondary "burner" phone for sensitive communications and suggests leaving primary devices at home whenever possible.
Moreover, the guide offers guidance on preparing for potential device confiscation, including encrypting sensitive data, setting up remote wipe capabilities, and memorizing crucial contact information. It also advocates for educating oneself about local laws regarding surveillance and data retention, empowering individuals to assert their rights effectively. Finally, the guide concludes by underscoring the ongoing nature of digital security, emphasizing the need for continuous learning and adaptation to evolving threats. In essence, this guide provides a thorough and practical resource for protesters seeking to protect their digital privacy and security in a potentially hostile environment.

Hacker News users discussed the practicality and necessity of the guide's recommendations for protesters. Some questioned the threat model, arguing that most protesters wouldn't be targeted by sophisticated adversaries. Others pointed out that basic digital hygiene practices are beneficial for everyone, regardless of protest involvement. Several commenters offered additional tips, like using a burner phone or focusing on physical security. The effectiveness of GrapheneOS was debated, with some praising its security while others questioned its usability for average users. A few comments highlighted the importance of compartmentalization and using separate devices for different activities.
The Hacker News post titled "The protester's guide to smartphone security" (linking to an article on PrivacyGuides.org) has generated a moderate number of comments, mostly focusing on practical aspects of the advice offered in the article and expanding on specific points.
Several commenters discuss the trade-offs between security and usability. One points out the difficulty of following all the recommendations while still maintaining a functional device for daily use. They highlight the challenge of balancing the need for secure communication with the practicality of accessing essential services and maintaining contact with people who aren't using secure platforms. Another echoes this sentiment, arguing that the level of security suggested in the guide might be excessive for most protesters and could hinder their ability to organize and communicate effectively. They suggest a more tiered approach, offering different security levels based on the individual's risk profile.
A recurring theme in the comments is the importance of threat modeling. Commenters emphasize that the appropriate security measures depend heavily on the specific threats a protester might face. For instance, someone protesting a local issue faces different risks compared to someone involved in activism against a powerful authoritarian regime. One commenter suggests focusing on specific risks, like location tracking and data extraction from a confiscated device, rather than attempting to achieve absolute security.
There's also a discussion about the effectiveness of certain security practices. One commenter questions the advice to disable biometric unlocking, arguing that a strong passcode is sufficient. They suggest that the risk of forced biometric unlocking is relatively low in most protest scenarios. Another commenter challenges the recommendation to use GrapheneOS, suggesting that CalyxOS might be a more practical alternative for less technically inclined users.
A few comments dive into technical details. One provides specific instructions on how to disable location services on different Android devices. Another discusses the importance of using end-to-end encrypted messaging apps and recommends specific apps known for their strong security features.
Finally, some comments offer additional advice not explicitly covered in the article. One suggests carrying a "burner" phone for sensitive communications and keeping a separate device for everyday use. Another emphasizes the importance of physical security, reminding protesters to be mindful of their surroundings and avoid leaving their devices unattended.
While the comments don't offer groundbreaking new information, they provide valuable context and practical considerations for anyone looking to implement the security advice offered in the linked article. They highlight the importance of balancing security with usability, tailoring security measures to specific threats, and understanding the limitations of different security practices.
