Since it was said, 1 bit is flipped, just tried brute forcing bit flip and dumped all the images, then ran tesseract to extract the text, then grep'd for SECCON and got the flag.
```
with open("broken.jpg") as f:
a = f.read()

def flip(er, n):
return chr(ord(er) ^ (1<<n)) for="" i="" in="" xrange(1000):="" for="" j="" in="" xrange(8):="" b="a[:i]" +="" flip(a[i],="" j)="" +="" a[i+1:]="" with="" open("temp="" "="" +="" str(i*10+j)+'.jpg',="" 'wb')="" as="" f:="" f.write(b)="" ```="" `for="" i="" in="" *;="" do="" tesseract="" $i="" stdout="" 2="">/dev/null; done | grep SECCON`
