GrammarViz 3.0. Time series anomaly and recurrent pattern discovery made interactive GrammarViz approach for time series pattern discovery is based on two algorithms that have linear time and space complexity: (i) Symbolic Aggregate approXimation (SAX), that discretizes the input time series into a string, and (ii) Sequitur, that induces a context-free grammar (CFG) from it.
Recently, we added another grammar induction algorithm called Re-Pair, which is a bit slower than Sequitur, but powers an additional capability of our tool -- the automated discretization parameters selection. By exploiting the hierarchical structure of CFG, GrammarViz is able to identify rare and frequent grammar rules in real time, i.e., along with the signal acquisition.

The main purpose for doing so is finding out which file was damaged in the event a storage device develops any bad sectors (that way you will know if you lost anything important). For most of these commands you will have to be either root or a user that has direct read access to the drive you are checking (being a member of the disk group should be enough). As usual, a current backup is always a good idea, especially if imminent drive failure is suspected. S.M.A.R.T. can help determining that. Finding bad sectors.

My thanks to Dave Kleiman (one of the original papers co-author's with myself) for reviewing and adding some details to this post series. Due to the limitations of peer reviewed papers, much of the detail of a process is commonly lost. This series of posts will endeavor to fill out the areas that are not covered in the paper in any detail and also add some further level of knowledge.

A case can have a single data source or it can have multiple data sources. Currently, a single report is generated for an entire case, so if you need to report on individual data sources, then you should use one data source per case. Use PowerShell and Regular Expressions to Search Binary Data – Hey, Scripting Guy! Blog. Summary: Guest blogger and pioneer of the PowerSploit module talks about using Windows PowerShell and regular expressions to search binary data.
Microsoft Scripting Guy, Ed Wilson, is here. Today we kick off a four-part Windows PowerShell and security series with a new guest blogger, Matt Graeber. The Scripting Wife and I had the privilege of meeting Matt at the Windows PowerShell Summit earlier this year in Seattle. I was impressed with his commitment to Windows PowerShell and in the way he had been using Windows PowerShell in his security work.

How I Cracked your Windows Password (Part 2) If you would like to read the first part in this article series please go to How I Cracked your Windows Password (Part 1).
Introduction In the first part of this series we examined password hashes and the mechanisms Windows utilizes to create and store those values. We also touched upon the weaknesses of each method and possible avenues that can be used to crack those passwords. In the second and final article in this series I will actually walk you through the process of cracking passwords with different free tools and provide some tips for defending against having your password cracked.

" SysKey and the SAM. The Security Accounts Manager The Security Accounts Manager, or SAM, has been used by Windows since the days of NT to store information on local user accounts (or, in the case of a domain controller, the accounts for all users on the domain). It takes the form of a registry hive, and is stored in %WINDIR%\system32\config. Generally, two types of hash are stored in the SAM: the LanMan hash and the NT hash. The LanMan hash has many flaws: It is not salted, and is thus vulnerable to precomputed dictionary attacks such as rainbow tables. The NT hash, by contrast, is simply the MD4 hash of the password (encoded as UTF-16 little endian). The SAM before Windows 2000.
