Interesting parts are:. There's a check for constant 0x47A. So it's some sort of checksum. Now you can go further.. Call at address C6 has one argument on stack - entered serial number.
So, this must a be a very interesting method. Put memory breakpoint on the argument in stack, run and breakpoint will hit inside mscorlib. Step out until JIT'ed code and you'll be somewhere here:. Quick google search confirms that.
Breakpoint on byte array, run. See byte array converted to hex string. Breakpoint on string, run.. See 2 strings being compared. Problem solved. CodeCracker vstrange Im on. HI, CodeCracker. You need to be a member in order to leave a comment. Sign up for a new account in our community. It's easy!

Volume Count: Similar to the detection count, the Volume Count is specifically based on the number of confirmed and suspected threats infecting systems on a daily basis. High volume counts usually represent a popular threat but may or may not have infected a large number of systems. High detection count threats could lay dormant and have a low volume count.
Criteria for Volume Count is relative to a daily detection count. Trend Path: The Trend Path, utilizing an up arrow, down arrow or equal symbol, represents the level of recent movement of a particular threat. Up arrows represent an increase, down arrows represent a decline and the equal symbol represent no change to a threat's recent movement. The percentage impact correlates directly to the current Trend Path to determine a rise or decline in the percentage.
Technical Details File System Modifications Tutorials: If you wish to learn how to remove malware components manually, you can read the tutorials on how to find malware , kill unwanted processes , remove malicious DLLs and delete other harmful files. Exe File name: ErrorGuard. Exe Size: 1. The following cookies were detected: errorguard. James K Nduli says:. March 8, at pm. Robbin R.
Because of this, spyware, malware and adware often store references to their own files in your Windows registry so that they can automatically launch every time you start up your computer.
To effectively remove ErrorGuard from your Windows registry, you must delete all the registry keys and values associated with ErrorGuard, which are listed in the Registry Keys and Registry Values sections on this page. Ransomware is malicious software that encrypts the hard drive of the infected computer or the files holding important information.
Small-charge or free software applications may come bundled with spyware, adware, or programs like ErrorGuard. Sometimes adware is attached to free software to enable the developers to cover the overhead involved in created the software. Spyware frequently piggybacks on free software into your computer to damage it and steal valuable private information. The use of peer-to-peer P2P programs or other applications using a shared network exposes your system to the risk of unwittingly downloading infected files, including malicious programs like ErrorGuard.
When you visit sites with dubious or objectionable content, trojans-including ErrorGuard, spyware and adware, may well be automatically downloaded and installed onto your computer. The initial incarnation of EfiGuard as a bootkit was an attempt to get dude's UEFI-Bootkit to work with recent versions of Windows 10, because it had become dated and no longer works on the latest versions like UPGDSED, often caused by version-sensitive pattern scans.
While I did eventually get this to work, I was unsatisfied with the result mostly due to the choice of hooking OslArchTransferToKernel , which as noted above executes in protected mode and after ExitBootServices has been called. Apart from this, I was not satisfied with only being able to patch some versions of Windows 10; I wanted the bootkit to work on every EFI-compatible version of Windows x64 released to date.
Because of this, I rewrote the bootkit from scratch with the following aims:. A big picture overview of the final EfiGuard boot flow is shown in the diagram above. EfiGuard is licensed under the GPLv3. Skip to content. Star Branches Tags. Could not load branches. Could not load tags. Latest commit. Mattiwatti Fix build with current EDK2 master.
