The LisfonService Trojan is a dangerous weapon used by the hacking collective called MuddyWater which has used it against high-profile government organizations across different countries in the Middle East. It is used in conjunction with other tools in order to carry out complex intrusions against them. This particular malware is noteworthy for using a large network of proxy URLs, this makes it very difficult to construct a viable and stable defensive system based on blacklisting certain URLs. The hackers will maintain and coordinate the malicious network so that the dangerous infrastructure can always be used in forthcoming attacks. It allows for flexible delivery methods to be used. Some of the most common ones include the following:
- Direct Attacks — The criminals can use their infrastructure in order to scan the target computers for any vulnerabilities. Using an automated utility it can probe vulnerabilities against whole networks.
- Phishing Messages and Sites — The criminals can pose as messages and sites that will appear as being sent or directed from a legitimate or known company or service. The messages and sites will appear as being hosted on similar sounding and legitimate sounding domain names. Furthermore their body contents and style can lead to the virus deployment. To make them appear as more legitimate the hackers can embed self-signed or stolen certificates.
- Payload Delivery Files — The criminals can program various payloads in order to help deliver the threat to the targets. They can be infected documents of all popular formats (spreadsheets, presentations, text files and databases) which will request that the victims to enable the built-in scripts thus triggering the infection. Another popular type of infection is the creation of dangerous setup files of the most popular programs: system utilities, creativity suites, office and productivity apps. When they are opened by the users the virus infection will start automatically. Finally the use of browser hijackers can also be used to infect the target users. They are dangerous web browser extensions which are uploaded to the relevant repositories using fake user reviews and developer credentials.
- File Sharing Networks — All payloads and other virus contents can be shared on networks like BitTorrent where both legitimate and pirate data is found.
Without regard to the actual infection source as soon as the deployment is made the built-in behavior pattern will launch. One of the first modules which are run following the infection is the information acquisition component which will extract information about both the victims and the infected computers themselves. This can be used by the criminals in order to conduct crimes such as financial abuse and identity theft which is a dangerous tactic. The criminals can also opt to generate an unique ID which is created by an algorithm which takes its input sources from strings like the installed hardware components, user configuration and etc. The extent to which data is acquired includes information like the operating system type, build version, domain and public IP address. The bulk of this information will be communicated to the hackers via a special connection which is both secure and persistent.
This connection is used by the hackers in order to receive the sensitive information about the compromised machines and it can be used to deploy other threats to the computers, as well as take over control of them.
Such infections are really dangerous as they can be used to infect other computers found on the local network or make the infected hosts part of a worldwide botnet network. Further changes can be added dynamically as the hackers see fit.

Hacker-made sites that pose as legitimate download portals, search engines and software product pages will scam the users into downloading and running the application. They are generally hosted on domains that sound similar to popular sources and may include self-signed security certificates.
To increase the number of infected victims the criminals can also place the LisfonService Trojan in payload carriers such as macro-infected documents and malware application bundles.

Such infections can also be spread via browser hijackers which are dangerous web browser extensions that are usually uploaded to the repositories of the most popular browsers.
LisfonService – What Does It Do
The LisfonService Trojan upon execution will start its infection process as soon as the infection occurs. Its main goal is to start a secure and persistent connection to a hacker-controlled server. It allows the criminals to take over control of the affected computers, steal their data and deploy other threats.
Such malware can execute many different tactics depending on the exact attack campaign. Most of them are used in order to serve as payload carriers for other threats. Popular options are the following:
- Data Theft — The LisfonService Trojan may include an information harvesting ability which is capable of acquiring data that ca directly expose the identity of the victim users.
- Machine Identification — Many similar threats are programmed to extract the list of installed hardware components ,specific operating system environment values and user settngs which are then processed by a special algorithm that will output an unique infection ID that is to be assigned to each different computer.
- Windows Registry Changes — The LisfonService Trojan can create entries for itself in the Windows Registry which can make its removal more difficult. If it edits existing values then serious performance issues can arise. Data loss and errors are a common side effect of this operation.
- Boot Menu Options Modification — Some LisfonService Trojan versions can modify the boot options in order to automatically start themselves when the computer is powered on. By disabling access to these options manual user removal guides can become worthless.
- Data Removal — The engine can be configured to locate and delete files such as system backups, restore files and shadow volume copies. This makes recovery much more difficult and in this case the use of a data recovery solution needs to be used.
Any future LisfonService variants can include other malicious actions as per the hacker’s instructions.
