With hundreds of millions leaked passwords resulted from several breaches in the past years (LinkedIn, Myspace), wordlist rule-based cracking can produce surprising results against complex passwords with more entropy. For an 8-character password, GPU rigs of 4 such cards can go through an entire keyspace of upper/lower alphanumeric + most commonly used special characters ( #$%&) in less than a day.

NetNTLMv2 hashcat benchmark for a single Nvidia GTX 1080 card is around 1600 MH/s. Regarding password cracking feasibility, this improved greatly in the past few years with GPU-based cracking.

While password hashes are submitted, the researchers note that cracking those passwords should not take decades anymore unless they are of the complex kind. What happens then is that the server requests authentication, and that the system will provide that. The attackers use a SMB server location for the icon. This means that attackers could easily hide the file behind a disguised filename such as image.jpg. What's particularly interesting about the format is that it may load resources from a remote server.Įven more problematic is the fact that Windows will process these files as soon as you open the directory they are stored in, and that these files appear without extension in Windows Explorer regardless of settings. The aging format is a plain text file that includes instructions, usually an icon location and limited commands.
