SDBbot Trojan Update April 2020
The hacking group known as TA505 has launched a yet another attack campaign leveraging the SDBbot Trojan against large corporations. The latest attack is against enterprise networks across Europe. The criminals are using phishing emails that are designed as being sent by HR staff from Onehub – a legitimate service used by many companies.
The messages contain file attachments which are text documents called Resume.doc, when they are opened by the victims a prompt will be spawned asking the users to enable the built-in code. This will trigger a payload download function via a DLL file. The analysis of the contained within files reveals that the first function will be to extract the configuration settings of the Active Directory implementation used for network login. It is used to infect the computer with the Trojan.
Other features of the Trojan are a persistent mechanism which ensures that the threat will be started as soon as the computer is started. The built-in password credentials harvester will also execute in order to acquire sensitive content.
SDBbot Trojan — Update October 2019
The TA505 hacking group has been found to orchestrate a mass email phishing campaign by sending out messages that appear as sent by legitimate services. They will attempt to manipulate the users to interact with the shown contents, download and run files or open up links. This behavior is expected as many of the most common approaches will be used:
- Update Notifications — The email messages will state that important software will need to be patched. The proposed updates will be attached or linked in the email.
- New Application Information — This is another common practice which will manipulate the users into believing that they need to install a new software that will provide newer functionality for something that they already use.
- Files Delivery — Among the most common scenarios is the simple file transfer which will impersonate friends, relatives or colleagues.
- Pirate Content — Often users will be presented with links to download expensive software. Through the given links the malware will be downloaded.
The email messages can be automatically translated using Google Translate or other software in order to target specific users and their locations. The two most widely used files in this campaign are the following:
- Malware Documents — These are macro-infected documents which can be of all popular file formats. When opened by the victims a prompt will appear asking them to enable the built-in code. This will trigger the infection process.
- ISO Files — These are image files which are usually installers of software or carry important software. They can be accessed by most operating systems and the most common way of interacting with them is to “mount” them in the file manager.
SDBbot Trojan — How Did I Get It
The SDBot Trojan is a malware threat which is being launched by the TA505 hacking group, they are known for causing a lot of high-profile attacks against both government and industry targets.
The security analysis shows that the method of distribution is the organization of phishing strategies. This is done by using an initial downloader that is delivered alongside the contents.
The confirmed targets so far include organizations and high-profile targets in the following locations: Singapore, Georgia, Sweden, Greece, Lithuania, United Arab Emirates and etc. In seems that there is an emphasis on financial countries which are spammed with fake notifications that are written in both English and Greek. The email messages include a malware Excel spreadsheet file. When opened it will either automatically start the built-in scripts or prompt the victims to do so.
Another strategy which was employed by the hackers is the sending out of shortened URL file — it will redirect the victims to a hacker-controlled page which contains the malware Excel file.
This shows that it is very possible in the future the TA505 hackers to use other techniques in order to deliver the SDBot. The most popular alternatives are the following:
- Infected Setup Bundles — The hackers can create dangerous installers of popular software which are often downloaded by end users. They can be shared on hacker-made sites, social network profiles and file-sharing networks.
- Malware Browser Plugins — These are dangerous extensions which are made compatible with the most popular web browsers. The malware plugins will be uploaded to the relevant repositories with hacked or specially made developer credentials. The posted descriptions can promise a variety of feature additions or performance optimizations.
- File-Sharing Networks — The malware files that will deploy the threat can be shared over different file-sharing networks such as BitTorrent.
SDBbot Trojan — Capabilities
The virus installation begins by a the execution of the initial malware dropper which will launch the main engine of the Trojan and all associated modules. One of the first actions which are done is the data collection of sensitive information. According to the conducted security analysis this can include data that can be categorized into two main groups:
- Personal Information — This includes information that can reveal the identity of the victims including a person’s name, address, mobile phone number and any stored account credentials.
- Machine Information — The engine can create a list of the installed hardware parts. The information can then be used to construct an unique ID that can be placed on every infected machine.
The next step is to enable the actual Trojan operations — this will setup a persistent connection to a hacker-controlled server which will be kept running for as long as possible.
The hacking group has also embedded other options like modifying the Windows Registry. At any time the active infection can be used to deploy other modules, as well as viruses onto the compromised hosts.
