1. Right-link, click on the new tab to open the link, save the attachment
2, began a picture steganography routine. . . .
①, double-click to open the picture and found a problem with the width and height, color of the background lacks the problem
modify the width and height: In fact, nothing special. . . . . . . . .
②, right, property details, nothing special
③, Open, notepad, search, something not match, nothing special bottom string, but it is very special, as shown below:
888,888,888,888,888 8888888888888 88888888
④, dragged 010edit, search 504b 0304, match and nine archive
We use binwalk, look at what things steganography:
of Foremost, isolated from a compressed package, get unpacked:
// this gif picture
⑤, for more than eight special document, we use the file command to view file properties, Discovery two, three, four very special
for its foremostf three documents were obtained:
foremost 88, get the picture contains a two-dimensional code to obtain a scanned: bilibili
of Foremost 888, get a picture, we have the right property, get detailed information c2lsaXNpbGk string after string = base64 encryption, decryption too: silisili
of Foremost 8888, to obtain a two-dimensional code image, scan obtained: Panama
⑥, according to the task presenting: flag format flag {xxx_xxx_xxx}, so the flag is {bilibili_silisili_panama}
0x03、Flag
flag 为 bilibili_silisili_panama {}
0x04, tools
1, two-dimensional code scanning tools: CQR
