binwalk開 發現裡面有夾zip foremost 分離出來

.
├── audit.txt
├── png
│   ├── 00000000.png
└── zip
    └── 00000094.zip

發現00000094.zip裡的png的crc32是cdad52bd,跟00000000.png的crc32一樣 利用明文攻擊 先把00000000.png壓成plane.zip

./pkcrack -C ../output/zip/00000094.zip -c meow/t39.1997-6/p296x100/10173502_279586372215628_1950740854_n.png -P ../output/png/plain.zip -p 00000000.png -d res.zip -a

-C:要破解的目标文件(含路径)
-c:破解文件中的明文文件的名字(其路径不包括系统路径,从zip文件一层开始)
-P:压缩后的明文文件
-p:压缩的明文文件中明文文件的名字(也就是readme.txt在readme.zip中的位置)

flag:FLAG{pkcrack is your frien. MEOW, MEOW, MEOW~}

5 where is flag

cat flag|grep -oE "FLAG{[a-zA-Z0-9_]*}" flag:FLAG{VizQLeu9M3aybJBA3f1AgFROGyuTLXZ2oeRbKf1Agf1AgFLAG9hBTI}

8 pusheen.txt

給你一堆貓貓,黑貓當成1、白貓當成0,binay to string flag:FLAG{Pusheen OIOOOIIOOIOOIIOOOIOOOgOOIOIOOOIII Cute}

  • 爆破用regex找flag
  • 或是用改hex拿掉重複的,然後改file header的crc32或是foot 看xz的文件應該是這樣沒錯(?)(我沒弄) flag:FLAG{Really long file}

10 otaku

11 buzzing

12 drvtry vpfr

給你神奇的字,其實就是鍵盤打字時往旁邊的按鍵按 flag:FLAG{Shift My Keyboard And Typing Something}

13 bzbz

找bilibli外洩的原始碼 https://github.com/fitlivingmm/bilibili/blob/master/go-common/app/admin/ep/melloi/cmd/convey-test.toml 裡面有帳密、登入就好 flag:FLAG{Let's learn golang from bilibili}
