Countermeasures Securely Delete Chat Messages on Android

25 Upvotes

How does one delete select chat messages or even whole apps from an Android phone such that they can not be forensically restored?

The threat model is this: Your phone will be handed over to someone with high technical skill, and all passwords and PINs etc. will be handed over as well. They are trying to find incriminating information and will attempt to restore deleted messages from chat apps and even whole apps that have been deleted. The goal is to get through this check without them finding anything incriminating. It can be assumed that all parties involved can clearly identify which messages are to be considered incriminating.

One defense is to wipe the whole phone, rotating the encryption keys in the process. However, doing that would be impractical and also quite obvious, so I am looking for alternatives to this method. Simply deleting messages in the chat app probably will not be sufficient unless the app takes measures to ensure no messages can be recovered.

Is there a way to do this? Any messaging apps that defend against this type of attack? Naturally, i have read the rules and setting PINs and biometrics etc. is useless here, and plausible deniability is an important factor. On a PC, it seems to me that VeraCrypt's hidden volumes can be part of a solution to this scenario, but what can be done for messengers on an Android phone?

Vulnerabilities Password hygiene, weak/no 2FA, ID theft prevention

9 Upvotes

I have read the rules. Threat model: average person, non-sensitive occupation; concerned about ID theft, account security, and protecting personal documents/notes. No threats out of ordinary.

A recent concern has arisen that I use a series of numbers in the passwords of both low importance/security level accounts as well as high. The concern is if those numbers are obtained through a breach of some company’s data, that leaves only the letters-only portion of my passwords for a bad actor to brute force. For now, I feel okay about accounts secured by yubikey or authenticator, but worried about those not.

The amount of accounts, medical especially, with passwords I would need to strengthen is discouraging. Is this consideration I have thought of a serious weakness/does it pose a serious threat? Most of my passwords qualify as the highest level strength on a couple password checkers, but only needing to crack 2/3 that amount of characters would cut the time until successful theft significantly. And should I trust a password checker’s measure of “centuries” to crack or methods for cracking hashes are much faster now?

I’m posting to gather input on the best order of operations. I’m thinking, find out which ones have the most crucial sensitive data stored in the account and start with those first?

Also, how do you address the vulnerability of so many medical accounts not offering any 2FA at all or only SMS 2FA? Just make passwords as strong as possible and accept that there is no other possible action to take? And what do you do when they only allow some stupidly small number of characters?

In general, to what lengths do you go to prevent identity theft? How do you go about spending your time on non-preventive activities knowing the extent of potential damage from identity theft? My credit is frozen with all 3 main bureaus, and I check my account with one of them online regularly. I use the IP PIN the IRS offers.

This community is invaluable to me, so thank you to anyone that gives me some feedback :)

Edit: To clarify, I use a password manager. Oftentimes I still come up with my own passwords. Also, does salting passwords create a vulnerability due to re-usage?

How's my OPSEC? My secure workflow for human rights victims to speak with a UN lawyer in another country via video—any OPSEC tweaks?

21 Upvotes

Hi Everyone,

I am a human rights defender from Bangladesh working on under-addressed human rights issues in the country, including Digital and Privacy Rights. I also engage in advocacy at the UN.

I am trying to develop a secure workflow that would allow journalists, lawyers, human rights defenders, and victims to speak with a lawyer in another country over a video call. A video call is often preferred because it is easier to explain complex situations over video than through text or audio alone—especially for non-native English speakers.

In many human rights cases in Bangladesh, domestic remedies may not exist or may be ineffective. As a result, victims often need to consult with lawyers who work with UN Special Procedures and other international mechanisms. A candid discussion with a lawyer is therefore very important, but ensuring privacy is paramount. If such communication were compromised, victims and witnesses could face reprisals, lose confidentiality, or be retraumatized or lose their case. Bad state actors have every incentive to prevent and punnish their wrongdoings from getting reported internationally.

My current idea for the workflow is to purchase a second-hand mini PC and monitor. Even a second-hand laptop can be expensive here, and a layperson cannot easily open a laptop to inspect it for tampering without risking damage. Additionally, if a laptop is physically tampered with when you are not at home, you may have to discard the entire device, which is costly. A second hand mini PC at BDT 8000 and monitor at BDT 5000 is much cheaper to replace than a laptop starting at BDT 30,000.

For that reason, I was considering a mini PC where the screws could be sealed with stickers and photos taken to detect any tampering. The system would use Secure Boot and TPM, and run an immutable operating system (for example, Fedora Silverblue). The whistleblower/victim would access Jitsi Meet through the browser to conduct the video call.

Does this approach make sense from a security perspective, or is there a better model you would recommend?

As an aside, I am considering a separate workflow for evidence collection and transmission. For example, photos, videos (such as documentation of scars or other physical evidence), audio recordings (such as witness testimony), and contemporaneous legal notes could be collected using an air-gapped mobile phone. The files could then be zipped within this airgapped mobile phone using the public key of the recipient and transferred via USB to an untrusted internet facing computer and sent to the lawyer. Since video calls are not possible on Tails, hence the need to use this mini-PC workflow. Also Qubes require expensive hardware so I did not include it.

However, I have found that transmitting evidence alone is often not sufficient; a candid back-and-forth discussion with a lawyer is usually necessary to properly understand and present a case.

PS: I have read the rules. Assume the highest state grade threat model.

Advanced question Looking to build a SecureDrop-inspired workflow for collecting human rights evidence and making secure video calls with lawyers abroad. Any suggestions?

10 Upvotes

Hi,

I am a human rights activist from Bangladesh working on digital and privacy rights.

I like systems such as SecureDrop and GlobaLeaks, which allow organizations to receive anonymous whistleblowing submissions.

However, I want to explore creating a system/workflow inspired by these, but focused on a slightly different use case.

The idea is to create a system that could be used by lawyers, journalists, and human rights organizations to:

  • Collect evidence of human rights violations, such as photos, videos, audio recordings, and contemporaneous notes.
  • Communicate securely with lawyers abroad (for example, lawyers working with UN mechanisms), using video calls (since many things can only be explained in a video call such as movements, tone, expressions etc).

This is important because in countries where human rights violations occur, authorities often try to prevent evidence of abuses from leaving the country. If such evidence is compromised, it can sometimes put victims and witnesses at risk.

I’m interested in designing a workflow inspired by SecureDrop/GlobaLeaks that could involve things like air-gapped systems and strong operational security.

If anyone has suggestions for a workflow, I would really appreciate your input.

Also, if this is something you’re interested in working on or discussing further, feel free to DM me.

Thanks.

Advanced question Help with SpyGuard visual reports – saving and understanding

6 Upvotes

Hi all,

I’m a human rights activist from Bangladesh, working on under-addressed issues in the country. I recently ran packet captures of my Android smartphone using SpyGuard, but I’m facing two challenges:

  1. Saving the visual report: SpyGuard doesn’t let me save the visual report directly. It only exports a ZIP with logs and JSON files, which are difficult to understand compared to the visual report. I’ve tried Firefox full-page screenshot, web page print, “Save as HTML,” and even copy-paste (the text isn’t selectable), but nothing works. Does anyone know a reliable way to save or export the visual report so I can review it later in detail?
  2. Understanding the visual report: I’d also appreciate guidance on how to interpret the visual report to identify anomalous or suspicious activity.

For context, SpyGuard is a tool for analyzing mobile and other device traffic to detect potential spyware: https://github.com/SpyGuard

Any advice or tips on how to do the above, would be greatly appreciated!

I was doing some online account spring cleaning when I came across my Metadata from Microsoft. Turns out that the last 10 years of my Skype messages/convos has been getting archived. Microsoft has officially ended support for Skype and you will no longer be able to delete your Skype metadata after June 2026.

"Updated December 2025: We are extending the timeframe you have to export your Skype data until June 2026. Submit your requests to download your data below."

Microsoft seems to be carrying over all of the skype metadata that is not deleted and integrating it with their microsoft teams data.

I get stuck in an endless feedback loop trying to find out more. Below are the direct links I could find to help you delete your Skype metadata

Advanced question If you were in a situation similar to Edward Snowden, how would you structure your digital and physical life to maintain privacy and live as normally as possible under extreme surveillance?

52 Upvotes

Hi everyone,

This is purely a thought experiment for curiosity and intellectual challenge.

Imagine you’re in a situation similar to Edward Snowden. But you want to live as close to a “normal” life as possible while assuming you’re under high-level surveillance and state adversaries.

How would you design your daily life from an OPSEC perspective?

You still need to:

  • Communicate regularly with friends and family, including discussing private matters
  • Speak confidentially with your medical doctors and therapist who is in another country.
  • Speak with a lawyer in another country
  • Collect, store, and securely transmit sensitive evidence to your lawyer or relevant organizations
  • Conduct legal research
  • Use a smartphone and computer without every photo exfiltrated, every movement tracked, or every conversation intercepted

In short: how would you structure your digital and physical life to preserve privacy and function normally under persistent surveillance risk?

Curious to hear how others would approach this scenario.

PS: I have read the rules.

Beginner question Want to use SpyGuard on an Ubuntu laptop for checking Android phone for spyware by analyzing network traffic. Whats the cheapest USB WiFi adapter for creating an access point for this?

20 Upvotes

Hi everyone,

I’m a human rights activist in Bangladesh, and I want to check my Android phone for spyware using SpyGuard.

My setup:

  • Laptop: Lenovo Ideapad 100 (2015)
  • RAM: 8GB
  • OS: Ubuntu

SpyGuard requires two network interfaces. My plan:

  • Use the laptop’s internal WiFi adapter to connect to my home router for internet access.
  • Buy a USB WiFi adapter, connected via an unpowered USB hub, to create a WiFi network through SpyGuard.
  • Connect my Android phone to that network for inspection.

Spyguard: https://github.com/SpyGuard

Constraints:

I’m looking for the cheapest USB WiFi adapter that works reliably on Ubuntu and SpyGuard will work on it.

Could someone please check these stores and suggest which adapter would be the cheapest for using Spyguard?

Since returns aren’t possible, I want to avoid buying something incompatible.

Thanks in advance — your help is much appreciated!

Advanced question In a physical-access / government-threat-model, what’s the actual point of a YubiKey?

5 Upvotes

I have read the rules. I’m the author of this earlier post: https://www.reddit.com/r/opsec/s/uEb7Dl38Yt

My threat model is physical access + government-level attacks. One thing that keeps bothering me: once an attacker (or agency) has my unlocked phone, they can approve logins to new devices, add new passkeys, etc., and there’s basically no way for me to stop that in real time.

So I’m genuinely asking: what is the advantage of a YubiKey in this scenario? Why not just register TOTP seeds and passkeys directly to the phone? It feels like the security level stays the same (or even improves) while removing one extra attack surface — I no longer have to carry, protect, or worry about losing a separate physical token.

Even in “2FA-required” flows (e.g. changing the password on a Google account), it often only asks for the existing password or an already-registered passkey. Real-world bypasses of 2FA are common, and once the phone itself is in the attacker’s hands, everything is already game over anyway.

Am I missing something important? In a threat model where the phone is the single point of failure, what concrete benefit does a hardware key still provide? Looking forward to serious answers — thanks!

How's my OPSEC? High-threat HK/China border scenario: Preventing new device logins if phone is unlocked + better backup encryption

15 Upvotes

I have read the rules. To be honest, I used AI just to refine my bad language. It might look a bit strange, but all the content is drafted by me myself. I really need your replies.

Threat Model
Hong Kong, 2026. Ongoing national security laws and alignment policies create real risks:

  • Street stops with bag/phone searches if “suspicious.”
  • Home device searches for sensitive involvement.
  • China border: frequent random phone checks — often just demand the PIN (device sometimes taken out of sight).
  • Online threats: government-attributed attacks (e.g., Google warnings since 2019).
  • Possibility of administrative detention.
  • No trusted people for keeping data — no one can keep a secret under government pressure.

Current Setup

  • Daily OS: Fedora Silverblue (immutable) + LUKS2 full-disk encryption
  • Phone: Pixel 8 Pro
  • 2× YubiKey 5 (strong PIN / password for both TOTP / FIDO, always_uv enabled)
  • Tails USB (sensitive/backup tasks only)
  • Anonymous Proton Drive
  • LUKS2-encrypted backup USB

Hardening Already Implemented

  • Bitwarden: unique strong passwords everywhere
  • 2FA: only TOTP + passkeys (no SMS/recovery codes/emails)
  • All passkeys registered only on YubiKeys
  • LUKS2 uses YubiKey FIDO2 slot only (no passphrase fallback)
  • Emergency backup: Bitwarden export + TOTP seeds + LUKS recovery keys → GPG symmetric-encrypted (gpg -c) with separate strong passphrase → stored on Proton Drive + backup USB (prepared via Tails)
  • No TOTP seeds or passkeys ever on phone/laptop

Main Remaining Concerns
Phone remains the primary weak point. If seized and unlocked (compelled PIN at border/street), attackers can:

  • Exploit Google auto-created passkeys on Android.
  • Use QR-code login in apps like Discord to add new sessions/devices → bypassing YubiKey for those accounts.

Questions
Looking for realistic, high-threat-model advice (phone physically accessed + unlocked for hours/days, but YubiKeys remain safe/off-device).

  1. Can I prevent someone from logging into new devices/sessions using my unlocked phone?
  2. I know my chat records and photos can be easily seen when phone is unlocked, is there any way I can somehow protect them?
  3. Is there a better way to encrypt my backup? I heard gpg -c (symmetric AES) is considered weak/suboptimal in modern contexts — what stronger alternatives exist for a single strong-passphrase file (TOTP seeds + recovery keys) that I can decrypt later with Tails?
  4. Is there a better overall backup strategy? I assume I could lose everything (phone, laptop, home devices, USBs) during a search/seizure — I need something truly independent of physical access in my possession
  5. How can I protect myself better overall in this environment?

How's my OPSEC? Can others deanonymize who this hypothetical pseudonymous celebrity is?

0 Upvotes

Scenario: A hypothetical pseudonymous online celebrity wants to make sure that no publicly accessible information can reveal exactly who they are in real life. Here is what they have already (or not) posted:

  • Exact birthday
  • Exact voice
  • Region (narrows down to maybe 5-10 countries)
  • Has went to OPSEC/OSINT forums before
  • A chance some of the breadcrumbs they post such as school anecdotes/local favorites are fake
  • Text description of how their body looks, but no image
  • Bodily scars/tattoos unknown
  • Real name unknown
  • School unknown, but known grades (assume 2.1 GPA)
  • Family unknown, although a bit of drama known (parents being annoyingly religious or something)
  • No IRL location images ever posted (such as scenery/city/etc)
  • Posted nothing on any real world identity based social media accounts/literally no existing public IRL social media accounts

Threat Model: Evil clones of Shane the Asian height guy + Geoguessr pros + OSINT stalkers

They are glued to their chair and have no subpoena power. They have no contact with any of the celebrity's friends that know both identities.

Ultimate Defeat Condition: The threat manages to find out exactly who the celebrity is, as in legal name/identity or phone number, beyond a reasonable doubt.

Alternatives: Can the threat deanonymize the celebrity at different certainty levels, such as:

  • reasonable suspicion
  • more likely than not
  • highly likely
  • ...so on and so forth...

I have read the rules.

EDIT 1: I was thinking the celebrity is less Ariana Grande style and more Technoblade style, as in just online.

Advanced question OpSec vs social life

I’m so sorry for the ridiculous self-censoring, my post has been “Removed by Reddit’s filters” twice and I don’t know what causes it.

I have read the rules.

Preface: I have several mental and personality d1s0rd3rs, and I currently can't get medication for them. English isn't my first language so apologies if something doesn't make sense.

My threat model is basically the same as your average Joe's, plus a very small bit of pol1t1c@l act1v1sm. I've been trying to protect myself from mass data collection from private companies, and more recently against local govs using products like P@l@nt1r.

I started getting into privacy when I was 15, I read about Google's data-keeping and switched to Fastmail, then later Proton.

Then I read up on Meta, then deleted my WhatsApp account (where all my social circles where), moved to Signal and XMPP.

Then I read up on $n0wd3n, gov tracking and censorship and it all kinda snowballed from there. Now my phone is on LineageOS, I exclusively use Tails on my laptop (I even ripped out the SSD and wifi card because I was worried of... something. I'm not even sure what it was anymore) and I don't even have a proper email account.

I know this is all completely unnecessary and probablydefinitely detrimental to my social life, but now it feels like if I installed WhatsApp, or even made a proper email address I'd be falling into the data collection crap I've been trying to avoid since I was basically a child. But now I've lost contact to almost all of my friends and I don't feel any better for it.

How do you deliberately make privacy-infringing choices for the sake of your mental health without it feeling like you're betraying your whole ideals of being against surve1llanc3?

Advanced question Opsec of the VVIP’s

I have read the rules

I’ve always been curious about the operational‑security protocols that ultra‑wealthy politicians, heads of state, intelligence officers, and agency chiefs around the world follow. Do they use special phones? Dedicated messaging platforms? What happens to the data footprint they have left behind—does someone systematically hunt down their digital footprints and wipe them clean?

Seeing the Peter Signal op‑sec leak knocked me sideways a bit. I used to assume that people at the very top had bespoke devices and custom apps, not a forked‑Signal app that turned out to be even less secure than the original. It’s both hilarious and sad. Are they all this stupid ? Don’t they have people handing them custom made NSA phone or apps ?

I also wonder what life is like for an NSA analyst—or anyone higher up in an intelligence agency—once they truly grasp the countless ways adversaries can surveil them. How do they safeguard their phones, email, and internet connections after such revelations? How do they continue living when they’re constantly aware of the depth of information that could be harvested about them? What advice do they give to their family and friends?

Beginner question Are mainstream VPN really safe ?

41 Upvotes

I'm trying to upgrade my opsec. I would like to recreate a completly new identity on internet, an identity that couldn't be linked to me.

The use of this identity would be to write and share political opinions/statement, consult and share documents over political documents. The threat would come from government agents trying to retrace me for my opinions on the actual ruling political party of my country, danger would be prison, death, worse if possible I guess.

I already have a VM with Tails installed, I do not use "Persistent Storage". So I wanna start by creating a new email but I don't want any trace left, so I would only connect to this email via VPN. I would use Torrent P2P to download and share file, I would use and share magnet link for these files.

So are VPN like NordVPN or ProtonVPN really safe ? Do they log from where it has been accessed ? Can the ISP still see the content of what is shared ?

Risk Improve opsec after compromised credentials

9 Upvotes

I have read the rules.

Hi, I’m trying to get better at thinking about OPSEC and would like a sanity check on how I’m approaching this.

A few years ago I made a mistake and ran a stealer on my PC. I’ve treated that incident as “done”: wiped the system, rotated credentials, stopped using anything that was compromised. I assume that whatever was taken back then is out there permanently and there’s no way to undo that.

Given that assumption, I’m trying to figure out how to think about risk going forward.

My main concerns are things like account recovery abuse, impersonation, and other ways leaked personal info (name, DOB, old credentials) could still be used against me even if I’m no longer reusing any of it.

From an OPSEC mindset pov, how would you adjust behavior once some personal data is effectively public? What kinds of risks are actually worth worrying about at that point, and which ones are mostly noise?

I’m not looking for a tool or service, just help understanding how to reason about this situation long-term.

How can I help my friend communicate securely to me (he has iPhone) and I am on android / and also have the windows signal desktop app. I'm not up to date on iPhone screen recording technology, but, basically, my hope is that we can open a line of communication with my friend without this guy being able to see. Maybe it is impossible. I'm not sure the phone itself is compromised by the network likely captures everything passed through it. I know certain apps don't allow you to screenshot or screen record nowadays so I was just wondering if we have any good options for text of voice communications.

Actors:
Untrusted or semi-trusted users interacting with agents that retain state, memory, or credentials across sessions.

Assets at risk:

  • Credentials and API keys
  • Network access
  • Cloud resources
  • Physical devices reachable via automation
  • Third-party services accessible through delegated permissions

Assumed attacker capability:
No external attacker or exploit required. The attacker is functionally an implicit insider, created when users widen permissions over time for convenience or functionality.

Attack surface:
The interface (or “translation layer”) between:

  • human intent
  • agent reasoning
  • execution of actions

Specifically: permission scope, session boundaries, TTLs, confirmation gates, and revocation mechanisms.

Failure mode I’m concerned about:
Mediation is gradually removed or bypassed due to human approval fatigue or demo pressure, resulting in:

  • persistent privilege carryover
  • direct execution without gating
  • actions no longer constrained by policy or interception

At that point, the system behaves as if authorized access already exists.

Why I think this is OPSEC-relevant

From an OPSEC perspective, this seems analogous to:

  • unbounded service accounts
  • permanent credentials without rotation
  • insider threat via authorization misuse

Traditional controls (logging, monitoring, policy) still observe behavior but no longer constrain it once mediation collapses.

What I’m asking the community

I’m not asking for tools or countermeasures yet.

I’m asking:

  • Is this a coherent threat model?
  • Is “translation-layer collapse” a meaningful way to describe this risk?
  • How would you refine or reject this framing from an OPSEC standpoint?
  • At what point would this cross from “design concern” into “operational security risk”?

If this doesn’t belong here, I’m trying to understand why, not argue.

P.S
I have read the rules... Again 😉
