Subject: false positive for dmg?
hello,
using the latest bleeding jumbo on mavericks, i have a dmg that i have been
bruteforcing in incremental mode with . i was surprised to see a result so
soon.
the command i am using is
john password.hash -inc:LowerNum
however, when i try to open the dmg, it does not accept the password. i
have tested this build of john with many other encrypted dmg and it always
gave the right password. but could this be a false positive?
the dmg was made in 2004. i have tried dmg2john and dmg2john.py with the
same result.
on a 32-bit windows 7 machine, with pre-compiled binary, i get a different
response and password does not match. see below:
any help would be appreciated. thanks!
