Recovering the file
We can use sleuthkit
and its tools fls
and icat
Looking at the file
output we now that this is an ntfs
file starting at 2048
so we use this in our fls
command
fls -o 2048 -f ntfs SVUSCG.dd-001.001r/r 4-128-1: $AttrDefr/r 8-128-2: $BadClusr/r 8-128-1: $BadClus:$Badr/r 6-128-4: $Bitmapr/r 7-128-1: $Bootd/d 11-144-4: $Extendr/r 2-128-1: $LogFiler/r 0-128-6: $MFTr/r 1-128-1: $MFTMirrr/r 9-128-8: $Secure:$SDSr/r 9-144-11: $Secure:$SDHr/r 9-144-14: $Secure:$SIIr/r 10-128-1: $UpCaser/r 10-128-4: $UpCase:$Infor/r 3-128-3: $Volumer/r 36-128-1: autorun.infd/d 37-144-5: bootr/r 52-128-3: bootmgrd/d 1120-144-1: CFFGd/d 53-144-1: efid/d 1119-144-1: EFSTMPWPr/r 1113-128-3: Email 2 Oct 1.pdfr/r 1114-128-3: Memo Oct 5.pdfr/r 1111-128-3: Perf Oct 20.pdfr/r 1112-128-3: Resignation Oct 21.pdfr/r 63-128-3: setup.exed/d 64-144-6: sourcesr/r 1115-128-1: stuff.txtd/d 997-144-1: supportd/d 1116-144-1: System Volume Informationd/d 1104-144-1: upgrader/r 1110-128-1: VeraCrypt Setup 1.26.7.exe-/r * 1136-128-3: 2025-06-04_11-48-36.jpgV/V 1280: $OrphanFiles
Based on the output the only file that was delted was 2025-06-04_11-48-36.jpg
so now we extract that using icat -o 2048 -f ntfs SVUSCG.dd-001.001 1136-128-3 > file.jpg
Now we just open file.jpg
and our flag is right there
