A python script and a PNG picture
Look though the script, it just put the flag in the **second bit of green channel** of the `unimportant.png`
```pypixel = (pixel[0],                     Red         pixel[1]&~0b10|(bits[i]<<1),  Green         pixel[2],                     Blue         pixel[3])                     Alpha```Wrote a [python script](solve.py) to extract the flag:```pyfrom PIL import Imagefrom Crypto.Util.number import long_to_bytesimport reimg = Image.open('unimportant.png')pixels = img.load()w,h = img.sizedef findFlag():	flag = 0	for i in range(w):		for j in range(h):			flag |= (pixels[i,j][1] & 0b10)>>1			flag <<= 1			if re.findall("tjctf{.*}",long_to_bytes(flag)):				print(long_to_bytes(flag))				returnfindFlag()```## Flag```tjctf{n0t_th3_le4st_si9n1fic4nt}```
