BorderLock
A consumer app for business travelers, journalists, and activists crossing borders in high-risk regions that locks sensitive memory regions before shutdown and verifies no residual data on next boot.
Business travelers, journalists, and human-rights workers crossing borders where device seizure is a real risk
- One-click 'cross-border mode' that triggers a memory scrub and forces a full shutdown with verified cold-boot state
- Pre-trip checklist that reminds the user to remove tokens, rotate credentials, and back up to encrypted cloud
- After-border 'clean boot' diagnostic that confirms no unexpected memory persistence from the prior session
- Optional secure travel pouch (faraday + cooling) for sale as hardware bundle
A widely-shared bare-metal RAM dumping tool on GitHub means the bar to performing cold-boot attacks has dropped from nation-state to individual, raising the stakes for anyone whose laptop may be seized.
CBP reports <0.01% of arriving international travelers had devices searched in FY2025; the real-world addressable set of journalists/activists/business travelers who both face seizure risk AND would pay for a consumer app is tiny.Border Search of Electronic Devices at Ports of Entry ↗A Journalist Security Checklist: Preparing Devices for Travel Through a U.S. Port of Entry ↗
Built-in OS pre-boot auth (BitLocker + TPM+PIN, FileVault) plus hardware mitigations like Intel TME already defeat the cold-boot threat at the disk-encryption layer; EFF and Freedom of the Press publish free checklists, leaving a narrow, commoditized gap.Intel Total Memory Encryption White Paper ↗Cold boot attack - Wikipedia ↗Preparing devices for travel through a US border - freedom.press ↗
Primary alternatives are free (EFF guides, OS-native FDE) and target users are price-sensitive activists/journalists; corporations route this through IT/MDM, not $50 consumer subscriptions.A Journalist Security Checklist ↗Border Searches | Electronic Frontier Foundation ↗
Cold-boot risk is a decade-plus stable concern, but the trajectory favors hardware-side fixes (TME, AMD SME, DDR5 on-die ECC) shrinking the residual problem rather than expanding it.Frozen Secrets: Cold Boot Attacks Unlock RAM's Hidden Data ↗Intel Total Memory Encryption White Paper ↗
Reliably wiping/verifying RAM contents across shutdown requires kernel/driver work, hardware-specific knowledge of memory topology, and survives poorly against DMA/Thunderbolt-class attacks that bypass it anyway.What is a Cold Boot Attack and how can you stay safe? ↗Physical Access Cyberattacks: How Can You Protect Yourself? ↗
