The Trojan concealing technology- Taking advantage of System Services Case study The definition of Trojan Trojan in the computer world is a program that can permeate the whole system without victim’s awareness. The Trojan runs in the victim system, like a spy that sneaks into enemy and opens back door for other kinds of attacks. This is like the Trojan strategy in real war, so the program is called “Trojan Horse” or “Trojan”. Trojan usually includes two executable programs: client and server. The Trojan that hides in the victim system is the server, and the so-called “hacker” uses the client as the control terminal. Once the server runs, it will open one or more ports on the victim system, initiating contact with the client and …show more content…
The official explanation from Microsoft is “svchost.ext” is the name of the generic host thread of the service that run from dynamic link library (DLL). When the system starts, “svchost.ext” check the value of the registry entry “HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\SvcHost” to construct the list of the services need to be loaded. Thus more than one “svchost.exe” thread will run at the same time. The screen shot of the registry entry that the Trojan queries is as following: picture 1 query the value of the registry entry As you can see in the Ollydebug handle window, the handle value corresponding to hKey that equals to 130 is “HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Svchost”. The screenshot is as follows: picture 2 handle of registry entry Then the Trojan continuously call “OpenSCManagerA()”, “OpenServiceA()”, “QueryServiceStatus()”, “QueryServiceConfigA()” to check the status of system services and try to locate the first service which is disabled and stopped. Firstly, “OpenSCManagerA()” creates a connection to Service Control Manager and opens specified database. Then “OpenServiceA()” opens a service which is already existed. The parameter “lpServiceStatus” of the function “QueryServiceStatus()” includes a pointer that points to the “SERVICE_STATUS” structure which contains service information. What the Trojan is looking for is the service whose value of the parameter “dwCurrentState” of “SERVICE_STATUS” structure is

They solution to these issues can be found by repairing the Windows registry first and clearing it off corrupted entries and unwanted files, with the help of 0x54504e26 fix tool Max Utilities. After completing that, to download and reregister the corrupted or missing files, in the Windows registry correctly, 0x54504e26 error repair software DLL Suite can be
Trojan’s are one threat it is a type of malware designed to provide unauthorized, remote access to a user’s computer. Trojan horses do not have the ability to replicate themselves like viruses; however, they can lead to viruses being installed on a machine since they allow the computer to be controlled by the Trojan creator.
After initial intrusion malicious software is installed on victim host that is re-ferred as RAT (remote access Trojan). RAT takes the responsibility to connect with attacker and regularly performed the actions that instructed by attacker. At this intruder take the full command and control (C2) over target host. The fact is that the initial connection is established by victim host, not by the attacker . This will happens mainly for two reasons: (i) organizations firewall usually allows the connections initialized by internal hosts, and (ii) this will help the attacker to not to detected easily. Because intrusion detection systems  can easily detect the extremely suspicious activity such as downloads from outside hosts.
First of all, I observed windows processes by using ‘Process Monitor’ application and found the suspect processes that start and stop in the short time period. Thus, the application tools that we need to use in this challenge are ProcessExplorer and ProcessMonitor. The ProcessExploere is using for comparison all of processes in assignment image OS, Windows-XP-Assignment.ova, and normal image OS, Windows-XP.ova. This tools will help us compare the different processes list between two images and lead us to easily isolate suspect processes that running in assignment image as shown in Figure 5 and Figure 6. About the ProcessMonitor, I used to observe the behaviours’ of suspect processes such as what they do, which processes they called, and/or what are the parameters they used to participate with other applications, also all of activities that they proceed, show on Figure 7. The difficult part that I found in this stage is how malware specify the targets and key for encryption. In this challenge, the new knowledge that I learnt is the malware do not need to create all code from scratch but they can build from any security application and make worst damage to social. In this case, they use gpg application also known as PGP, that the one of security application using for encrypt and sign data for secure communication and widely use in secure email
Name of Operating System is Microsoft Windows Server 2003 Service Pack 1. MS08-067: Microsoft Windows Server Service Crafted RPC Request Handling Remote Code Execution (958644) (uncredentialed check) i.e. the remote host is vulnerable to a buffer overrun in the 'Server' service that may allow an attacker to execute arbitrary code on the remote host with the 'System' privileges and risk factor is critical. The remote host implements TCP timestamps, as defined by RFC1323. A side effect of this feature is that the uptime of the remote host can sometimes be computed. The remote host seems to be a VMware virtual machine. The manufacturer can be deduced from the Ethernet OUI. It is possible to enumerate CPE names that matched on the remote system having risk factor none. A DCE/RPC service is running on the remote host with risk factor none. An ncacn http server is running on this port and a COM+ Internet Services (CIS) server is listening on this port. COM+ Internet Services are RPC over HTTP tunneling and require IIS to operate. CIS ports shouldn't be visible on internet but only behind a firewall. Also a DCE/RPC service is running on the remote host. It is also possible to obtain the network name of the remote host. The remote service understands the CIFS (Common Internet File System) or Server Message Block (SMB) protocol, used to provide shared access to files,
When all of a sudden, customers find a process in the Task Manager named CTF Loader, they fail to realize as to what it is. The file remains placed in the C:\Windows\SysWOW64 and it becomes difficult to determine if it is a virus or a genuine process. The file version is 6.3.9600.16384.
When BKDR_WIPALL.B is dropped, it stays latent for 10 prior minutes beginning to erase documents and halting the Microsoft Exchange Information Store administration. The vindictive code then goes latent again for two hours and makes system re-start it self. BKDR_WIPALL.B is exceptionally forceful and obtrusive. It actualizes a peculiarity that permits it to execute duplicates of itself with different limitation. With this system the mal-ware completes different program task, including erasing records and dropping extra segments. The extra segment "usbdrv32.sys" for instance gives assailants read/write access to introduced new files to the
This particular program is a Windows Trojan but what makes it unique is that it does not rely on the presence of a Windows binary file (an executable file on disk) to maintain its infection of a computer (Information on malware known as Poweliks, 2014).
Moreover, while looking at processes not identified as a threat by RedLine, one more suspicious process was identified. This process is named ‘UPnP.exe’. This innocuous looking file is an executable file that can be used to capture keyboard and mouse input and send it to a remote location (Spyware-net Database, 2016). All three of these processes are illustrated in Appendix A, figure 4. Additionally, all of these processes can be identified by performing a hidden/terminated process scan (‘psscan’) using Volatility (Appendix A, figure
It seems as if humans do not have respect for each other. People in different societies start wars in order to gain power or eliminate a potential threat. These wars were made possible because of technology and transporting. As technology and transport began to develop, the wars have started to become more of a bloodbath. According to the author of Guns, Germs, and Steel, Jared Diamond, it is believed that, “Technology, in the form of weapons and transport, provides the direct means by which certain people have expanded their realms and conquered other peoples”(Diamond 241). Technology is the source of many weapons that were ever used for war. Even the nuclear weapons the America uses now. In order for the military or even regular civilians
9. Are open ports necessarily a risk? Why or why not? They are a risk because a trojan can be used to transmit data to an attacker. They hold a port open, e.g. Port 31337. The attacker connects to the trojan and sends requests to do a certain task, for example to make a screenshot. The trojan makes the screenshot and sends the image via the port to the attacker. On newer trojans, the port number is quite freely configurable, which makes identifying the trojan by the port number difficult. There are no control mechanisms available which can prevent a trojan from using an specific port. If a trojan does use the port 80, for instance, a novice user could imagine the program is a webserver, and may even simply ignore the port.
If it wasn’t for me this war wouldn’t of happened and nobody would have suffered a painful death. I am the cause of the Trojan war me Helen the most beautiful mortal women alive. The soldiers are all fighting because of me. If I kill my self than I would save hundreds and thousands of lives. My own husband is fighting my former husband Menelaus and is probably going to die, and then I will have to go back to Greece with Menelaus. My beloved Paris the most beautiful man alive pretty as a god is going to die because of me. While I am in a palace watching brave courageous men die and the hands of each another.
Kronos is a banking Trojan. This rogue program has been in charge of blackmailing login credentials and financial details from a huge number of client accounts. The infection has propelled abilities and it is hard to recognize. The technical specifications of Kronos were uncovered in a malvertising forum where it was offered available to be purchased. The pernicious program is perfect with 64-bit and 32-bit rootkit. It highlights a formgrabber and a webinject which chip away at the most recent forms of Mozilla Firefox, Google Chrome, and Internet Explorer. The infusions are in Zeus config format which makes encourages the procedure. To protect Kronos from different Trojans, the hackers have executed a ring3 rootkit.
Detecting the presence of a rootkit on a computer can be difficult, as this kind of malware is designed to stay hidden and do its business in the background. There are utilities designed to look for known and unknown types of rootkits through various methods, including using signatures or a behavioral approach that tries to detect a rootkit by looking for known behavior patterns. Removing a rootkit is a complex process and typically requires the use of specialized
