Qbot Trojan – Virus Infection Methods
The Qbot banking Trojan is one of the most popular infections of this category of malware threats. As one of the oldest and most widely used viruses it has been used by many hacking groups around the world over the years. Qbot is best known for receiving constant updates and modifications to its core all the time. For this reason computer security researchers tend to focus on the current iterations when describing it.
The current attack is focused on using an updated distribution technique. The new Trojan engine is now programmed to hijack Microsoft Outlook email threads with the intention of creating and personalizing phishing email messages. The start of the campaign appears to be in March this year and continues to this day, so far 100,000 victims have been targeted in the USA, Italy, India and Israel.
The first detected instances of Qbot were detected back in 2008, the threat it also known as Qakbot among the security community. Current versions are very likely to spread using the Emotet malware. It is one of the most common infection vectors especially for Trojan threats and email SPAM messages. The Qbot-infected virus messages contains URLs or ZIP archives that all include Visual Basic Scripts which serve as the initial payload carriers. When the associated files are run the built-in code will trigger the virus deployment. The malware will be downloaded from a hardcoded URL contained in the script.
At the moment Qbot/Qakbot is being sent to the target users by relying on phishing messages related to the COVID-19 pandemic, tax payment reminders and job recruitment offers and procedures. The majority of attacks are against companies and organizations which are located in the United States of America and Europe.
Qbot Trojan – Virus Capabilities
The Qbot Trojan will start by running an email collector module — it will locate the locally installed Microsoft Outlook client and extract all email threads. They will be collected in a batch which will be sent to the hackers and reused in further email SPAM campaigns. This means that any further messages which are sent by hackers will appear as organic replies in their inboxes. In practice this will make differentiating between the legitimate and phishing content very difficult.
While the main Trojan engine is configured to take over control of the machines as well as steal any user and system files the recent updates to Qbot/Qakbot also add in other capabilities. Some of the added new modules include the following:
- Information Retrieval — The main engine can command a component to steal device information including sensitive users data and machine metrics. This can include the scanning of locally installed applications data which may contain sensitive users data: web browsers, email clients and password managers. The target data includes also email and web services login information and payment card details.
- Malware Installation — The Trojan can be used as payload carrier for other types of viruses. The most common ones which are delivered using such methods are file encrypting ransomware. They are designed to infiltrate the machines and process users data with a special cipher. The data types which are to be affected will be chosen from a built-in list of extensions. The processed data will renamed with a special extension and therefore made inaccessible to the computer owners. Ransomware notes or other means will be used to manipulate the victims into paying the hackers a designated decryption fee.
- Banking Trojan activities — This is one of the most important modules which have been integrated into the malware threat. It will monitor the users behavior and if they access an online bank or financial service a phishing overlay will be started. This means that every inserted character will be sent to the hackers which will allow them to take over control of the posted accounts. An alternative is the uploading of a keylogger script which will constantly keep record the keyboard input and mouse movement of the users. This is done in order to capture any entered in two-factor authentication codes.Banking Trojan activities — This is one of the most important modules which have been integrated into the malware threat.
