Recover data encrypted by C3RB3R / Cerber-family ransomware (the .L0CK3D file extension and the read-me3.txt ransom note) on Synology DSM or other Btrfs NAS devices without the key: restore original files byte for byte using old extents left behind by Btrfs copy-on-write, and verify them block by block with Btrfs checksums. Covers CoW / NoCOW determination, subvolume snapshot generation (lastsnap) effects, precise extent-tree reconstruction, inference for large files spanning multiple extents, statistics, export, validation, and reporting. Whenever users mention a NAS / Synology / black Synology being hit by ransomware, .L0CK3D, read-me3.txt, C3RB3R, wanting to recover encrypted Btrfs files, or ask "How can I recover if I have no backup and no snapshots?", use this skill even if Btrfs or extents are not mentioned. Use for ransomware recovery of .L0CK3D files on Synology/Btrfs volumes without the key.
