restic: encrypted and deduplicated backups

Summary

Alexander Neumann presents restic as a fast, verifiable backup tool with client-side encryption for local and remote storage targets. A convenient backup tool only increases security together with regularly tested recovery. Deduplication makes frequent snapshots affordable and shortens the window of possible data loss.

Ideas

  • Content addressing detects identical data regardless of file names and location.
  • Client-side encryption protects backups on targets that are not fully trustworthy.
  • Snapshots keep several states without complete copies of all files.
  • Integrity checks detect damaged or missing backup data.

Recommendations

  • Keep at least one backup outside the primary location.
  • Automate restic check and sample restores.

Recovering files encrypted by Black Basta

Tobias Mueller analyses the Black Basta encryptor and uses a faulty reuse of the keystream to recover files with a known-plaintext attack. Ransomware can undermine strong primitives itself through faulty use. Data recovery benefits from knowledge of file formats, reverse engineering and cryptography together.

MeshCore on 868 MHz: A decentralised radio network without the internet

Christian Stankowic and CodeSalat show how MeshCore and Meshtastic enable independent text networks and custom mesh bots with inexpensive LoRa hardware. Both projects build decentralised text networks on LoRa radio technology. Under suitable conditions, messages can cover many kilometres across several nodes.
