Hashcat version 5.1.0 är nu släppt

STÖK-Fredrik tipsade om att en ny intressant version av precis har släppts. Förutom de sedvanliga buggfixarna så finns det nu ett stöd för omskrivning för olika tangentbord när det gäller knäckning av / diskar.

För att förklara ytterligare: Oavsett vilken tangentbordslayout du har när du väljer ditt lösenord för kryptering av VC/TC-diskar så kommer tangentbordslayouten att vara US. Detta gör att sökrymden blir mindre eftersom flertalet specialtecken förenklas. Ta exempelvis följande exempel:

بين التخصصات blir fdk hgjowwhj[g

Så för varje tangentbordslayout så måste det finnas en mapping-fil. Det finns enbart för tyska i dagsläget men utvecklarna av hashcat vill gärna få in pull-requests via Github.

Changeloggen i sin helhet hittar du här:

  • OpenCL Devices: Add support for up to 64 OpenCL devices per system
  • OpenCL Platforms: Add support for up to 64 OpenCL platforms per system
  • OpenCL Runtime: Use our own yielding technique for synchronizing rather than vendor specific
  • Startup: Show OpenCL runtime initialization message (per device)
  • xxHash: Added support for using the version provided by the OS/distribution

Fixed Bugs:

  • Fixed automated calculation of brain-session when not using all hashes in the hashlist
  • Fixed calculation of brain-attack if a given wordlist has zero size
  • Fixed checking the length of the last token in a hash if it was given the attribute TOKEN_ATTR_FIXED_LENGTH
  • Fixed endianness and invalid separator character in outfile format for hash-mode 16801 (WPA-PMKID-PMK)
  • Fixed ignoring –brain-client-features configuration when brain server has attack-position information from a previous run
  • Fixed invalid hardware monitor detection in benchmark mode
  • Fixed invalid warnings about throttling when –hwmon-disable was used
  • Fixed missing call to WSACleanup() to cleanly shutdown windows sockets system
  • Fixed missing call to WSAStartup() and client indexing in order to start the brain server on Windows
  • Fixed out-of-boundary read in DPAPI masterkey file v2 OpenCL kernel
  • Fixed out-of-bounds write in short-term memory of the brain server
  • Fixed output of –speed-only and –progress-only when fast hashes are used in combination with –slow-candidates
  • Fixed selection of OpenCL devices (-d) if there’s more than 32 OpenCL devices installed
  • Fixed status output of progress value when -S and -l are used in combination
  • Fixed thread count maximum for pure kernels in straight attack mode

Technical:

  • Brain: Set –brain-client-features default from 3 to 2
  • Dependencies: Added xxHash and OpenCL-Headers to deps/ in order to allow building hashcat from GitHub source release package
  • Dependencies: Removed gitmodules xxHash and OpenCL-Headers
  • Keymaps: Added hashcat keyboard mapping us.hckmap (can be used as template)
  • Keymaps: Added hashcat keyboard mapping de.hckmap
  • Hardware Monitor: Renamed –gpu-temp-abort to –hwmon-temp-abort
  • Hardware Monitor: Renamed –gpu-temp-disable to –hwmon-disable
  • Memory: Limit maximum host memory allocation depending on bitness
  • Memory: Reduced default maximum bitmap size from 24 to 18 and give a notice to use –bitmap-max to restore
  • Parameter: Rename –nvidia-spin-damp to –spin-damp (now accessible for all devices)
  • Pidfile: Treat a corrupted pidfile like a not existing pidfile
  • OpenCL Device: Do a real query on OpenCL local memory type instead of just assuming it
  • OpenCL Runtime: Disable auto-vectorization for Intel OpenCL runtime to workaround hanging JiT since version 18.1.0.013
