Subject: Re: How do we purchase the Windows Pro version of the cracker?

Hi Dan,

Is there any specific reason why you want to purchase a product rather
than use a free John the Ripper jumbo build for Windows?  For example,
specific functionality or ease of use you're looking for, or desire to
support our project?

We do not have a Pro for Windows.  We do link to Hash Suite, but it's a
related project rather than a version of John the Ripper, so its
functionality is quite different - it offers a GUI (while John the
Ripper is command-line only) and better performance, but it supports
only a small subset of the targets (hash and file types) that John the
Ripper supports (currently just 14 vs. hundreds).

Thank you for letting us know.  That's really unfortunate.  Can you
please report this to Malwarebytes as a false positive and detrimental?

The reality is that so-called anti-viruses tend to detect password
cracking software as potentially undesirable, often blocking downloads
or even websites.  Checking e.g. VirusTotal, there's almost always some
non-zero detection rate for Hash Suite and for Windows builds of John
the Ripper, and it grows the longer the release has been out.  So yes,
ideally we'd be making releases far more often than we do.  Meanwhile,
it's up to you to choose between overly-aggressive anti-viruses and
password crackers.

VirusTotal shows me a 27/68 detection rate for Hash_Suite_Free_3_7.zip
(where Malwarebytes detects Generic.Malware/Suspicious, while e.g.
Kaspersky gives Not-a-virus:RiskTool.Win32.DumpReg.a), but somehow only
1/67 for john-1.9.0-jumbo-1-win64.zip (SentinelOne (Static ML) gives
Static AI - Malicious PE).  IIRC, it was actually much worse for John
the Ripper before, so maybe those tools are improving.  As to Hash
Suite, I think the higher detection rate is due to Hash Suite having
more Windows-native functionality, such as extraction of hashes from
Windows systems themselves.  With John the Ripper, you'd use external
PWDUMP tools for that (and there's a higher detection rate for those).

No, primarily because there isn't a Windows Pro version.
