Analysis of Petya extortion Trojan Recently, the security vendor G-Data released a report saying that a new extortion Trojan Petya was found. This trojan is characterized by first modifying the MBR Boot Sector of the system, then executing malicious code in the boot sector after forced restart, encrypting the hard disk data, displaying extortion information, and

The current network of the most rampant virus estimates are not Trojan horse program MO Number, now the Trojan attack more and more strong, in the process of hiding, very few independent exe executable file form, but instead into the kernel embedding mode, remote threading technology, Hook Psapi and so on, these Trojans are currently the most difficult to deal with. Now teach you to find and clear threads t

We know that under the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run can load the program, so that it automatically run when the boot, similar to "Run" Such subkeys have several places in the registry, starting with "Run", such as RunOnce, RunServices, and so on. In addition to this method, there is also a way to modify the registry to enable the program to start itself. Specifically, you can change how the file is opened so that the program starts with the type of f

Then deleted the automatic resurrection file mentioned at the beginning of the article.Summing up, encountered this problem, if not too serious, try not to re-install the system, generally is first off the outside network, and then use iftop,ps,netstat,chattr,lsof,pstree these tools, generally can find the culprit. But if you're having problems like that,/boot/efi/efi/redhat/grub.efi:heuristics.broken.executable FOUNDPersonally feel

Method One, Periodically check the WIN7 System Task Manager, if found to start running a large number of their own unknown procedures, it is necessary to be careful of themselves, these large number of unknown programs is likely to be Trojans attack their own computer precursor, because the general installation of Third-party software programs should not be much, And all users are familiar with, pay attention to see what the unknown name of the program is. Method Two, In the use of Windows7 o

The server only needs a simple line of code to use this program to achieve common management functions. 　　The code that runs on the server side is as follows: 　 The code is as follows Copy Code PHP: ASP: asp.net: (Note: ASP. NET to a single file or this file is also a JScript language) Client: There are special procedures, I often use the Chinese kitchen knife. Since it is a trojan, it can be used to invade yo

One: Frame hanging horse Where the "address" can enter a malicious Web site links, etc. Two: js file hanging Horse As long as the JS file, can be maliciously modified to be linked to malicious code, generally quoted by the entire station JS code is most likely to be linked to the Trojan, detection we can see the JS code on the left or below, the bad guys like the malicious code and normal code between a lot of space or return to hide, So to see more

This paper describes the implementation process of the file transfer method of the Trojan Horse under Delphi, and the concrete steps are as follows: Server-side code: Unit serverfrm; Interface uses Windows, Messages, sysutils, variants, Classes, Graphics, Controls, Forms, Dialogs, Comctrls, Stdctrls, Extctrls,winsock; Type Tfrmmain = Class (Tform) Panel1:tpanel; Label1:tlabel; Edtport:tedit; Panel2:tpanel; Stabar:tstatusbar; Savedia

The server was found to be planted a lot of Trojans, but also let people wantonly use ... NNDthe use of the method is also very simple, the local commit file point to the commit file, the inside of the PHP code will be executedThis is the only record, PHP must be a good filter system.
