Threat Database Malware Truebot Malware

Truebot Malware

Truebot, also tracked as Silence.Downloader, is a threatening program that has been used by cybercriminals to compromise victims' devices and add them to a botnet. It has the ability to download and install additional, hurtful programs or components on the infected device. The distribution and infection chain of this malware does not always take the same form, and it can vary greatly, suggesting that the attackers behind it are constantly adapting their tactics.

Worldwide Impact

The Truebot malware is a threatening form of harmful software used to infiltrate and take control of devices, networks and systems. It typically propagates through spam emails or by exploiting software vulnerabilities, allowing it to create large botnets made up of victim devices, but the infection vectors of the attacks have been observed to change often. So far, two particular Truebot networks have been identified by cybersecurity researchers. The first botnet is primarily focused on Brazil, Mexico, and Pakistan, while the second one appears to be targeting the US specifically.

Hazardous Capabilities of the Truebot Threat

Once fully established on the breached device, the Truebot threat can be used to inject various components and programs. Victims of Truebot attacks have reportedly been infected with the Raspberry Robin, the Cobalt Strike, FlawedGrace and the Clop Ransomware. In some cases, attackers have delivered the Raspberry Robin through Truebot, while in other instances, the deployment of the malware threats may have been in reverse order.

In addition, Truebot has been known to include an information-collecting component in its infections. In some cases, attackers have used this program to exfiltrate sensitive data and content from compromised networks, before launching a ransomware attack as a double extortion tactic. This means that victims will be threatened with a data leak if they do not comply with the attackers' demands for ransom payments. As such, it is important to protect devices from the Truebot malware by taking proactive cybersecurity measures.

Truebot Alert Issued in July 2023 By Government Agencies: The Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Multi-State Information Sharing and Analysis Center (MS-ISAC), and the Canadian Centre for Cyber Security (CCCS) are releasing this joint Cybersecurity Advisory (CSA) noted a surge in cyber threat actors deploying fresh malware variations of Truebot, also recognized as Silence.Downloader. Truebot is a botnet that has been leveraged by cyber groups like Russia's CL0P Ransomware Gang to gather and extract information from their targeted victims. In the past, hackers have predominantly distributed previous Truebot malware variants through phishing attachments.
