OceanLotus Trojan – Overview
The OceanLotus Trojan is a newly discovered threat which is used mainly as a payload delivery device. This is a collection of several tools that are used together in a complex attack scenario. According to the released reports the group has invested in the development of the tools and the way the intrusions are organized.
Trojan.MacOS.OceanLotus
The latest update of the Trojan is its capability to target macOS users. Its latest detection, Trojan.MacOS.OceanLotus, concerns macOS machines. The macOS backdoor provides attackers with access to steal confidential information.
Regardless of the OS targeted, the malware can be spread using a variety of tactics. Our security research shows that there are many versions using the OceanLotus name. This allows the criminal collectives to launch a multitude of attacks bearing different versions of the malware.
One of the main techniques is the coordination of phishing email messages which coerce the victims to interact with the included content. They are designed to appear as legitimate notifications sent from well-known services and companies. The OceanLotus Malware files can be either attached or inserted as text links.
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 OceanLotus Trojan in payload carriers such as macro-infected documents and malware application bundles. They are widely downloaded from the Internet by end users and may be found on file-sharing sites as well like BitTorrent.
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.
The OceanLotus Trojan is focused on infecting target networks and being used in targeted attack campaign. This means that the criminal collective behind it have been used in campaigns against both corporate businesses and government agencies in Asia: Laos, Cambodia, Vietnam and the Philippines. What is known about these particular attacks is that they are orchestrated by a very experienced hacking group. One of the common infiltration techniques is to coordinate phishing strategies — the hackers will send out bulk messages that impersonate well-known services or companies and urge the recipients into interacting with the shown contents. In most cases the e-mails will link to or attach a document file that will have infected macros. When the file is opened in the relevant office program a prompt will appear asking the victims to enable the scripts. If this is done the infection will begin.
The other popular technique which is used by the criminals is the so-called “watering hole infiltration”. This is done by intruding onto often visited sites nd replacing legitimate content with script installation of the OceanLotus Trojan.
The distribution of the threat is done by imitating the legitimate McAfee scanner files by injecting itself to a legitimate “On Demand Scanner” process. This means that the hackers will need to devise a way to deliver the necessary data. It is distributed in a package containing the hookup files and the payloads in a secure and encrypted form. The noteworthy feature is that steganography is used, a technique used to hide data within other data. As soon as the the initial intrusion is made a sequence of payload delivery which make use of benign-looking files which the process interacts with. Using decryption of the data a series of steps are done in order to provide the final payload. An interesting note is that one of the payloads inside the files is a mange image.
The second main payload has been found to have several versions, dropping files that have file names that may appear as legitimate applications and services. It will also launch a security bypass module which aims to identify and remove security software that can interfere with the proper malware delivery. The next step is to launch a modified version of the Remy backdoor. It will establish a secure connection to a predefined hacker-controlled server allowing the operators to take over control of the machines, steal user data and deploy other threats.
The associated DLL files are obfuscated in order to make it very difficult to detect that such an operation is being carried out. At least two different communications were observed during the intrusion attack. Various other threats can be loaded to the compromised machines such as the following:
- Ransomware — These are dangerous crypto viruses that aim to process sensitive user data according to a built-in list of target file type extensions. A preset extension can be added to the processed data.
- Trojans — Other Trojan threats can be deployed to the compromised machines. They allow the hackers to take over control of the systems and manipulate them into performing various tasks.
- Cryptocurrency Miners — They are scripts that are designed to retrieve and run a sequence of performance demanding mathematical tasks. Whenever one of them is completed cryptocurrency will be awarded to the operators.
Every infection can result in different behavior outcome as every machine can have different conditions.
