Five times faster brute force with 4-core CPU? Yes the new L0phtCrack 7 is now 5x faster than L0phtCrack 6 was. And if you have a system with AMD Radeon Pro Duo acceleration is amazing up to 500 times faster.
The L0phtCrack first released 19 years ago. A very powerful password cracker that forced the Microsoft to make improvements to the way Windows stores the hashes of the codes accesss. 
Microsoft finally eliminated weak LANMAN hash codes and started using only the strongest NTLM that it still uses up to date. However, password cracking algorithms and system hardware have improved significantly in the years to come.
The new version of L0phtCrack 7 shows that Windows passwords can be more easily broken today than it was before 18 years ago when Microsoft began making the necessary improvements to the stored passwords.
On a 1998 computer with a Pentium II 400 MHz CPU, the L0phtCrack prototype could break a Windows NT 8 character string (alphanumeric) within 24 hours. On an 2016 machine, L0phtCrack 7 can break the same password stored in the latest version of Windows 10 within 2 hours.
Windows passwords have become much less secure over time and are much easier to break from the Windows NT era.
Other operating systems, such as Linux, offer much safer password fragmentations, such as SHA-512.
