Pikabot malware, associated with the Water Curupira intrusion set, was used in phishing campaigns through 2023. Similar to Qakbot, it consists of a loader and core module enabling unauthorized access. The campaigns targeted victims via spam emails with malicious attachments, evolving to include a PDF file delivery method. Organizations are advised to adopt multilayered security measures to mitigate such threats.
The main takeaways from the meeting notes are as follows:
– A threat actor associated with the Water Curupira Intrusion set has been utilizing a loader malware called Pikabot in spam campaigns throughout 2023. This loader malware shows similarities to Qakbot and has been used in phishing campaigns targeting victims via email attachments.
– The malicious actors use various techniques such as thread-hijacking and disguising the attachment as a legitimate file to trick recipients into opening the attachment. These attachments contain obfuscated JavaScript or IMG files with the aim of executing the Pikabot payload on the victim’s machine.
– The Pikabot payload is a sophisticated multi-stage malware with the capability of unauthorized remote access and the execution of arbitrary commands through an established connection to the command-and-control (C&C) server.
– The threat actor behind Water Curupira has conducted several DarkGate spam campaigns and a small number of IcedID campaigns but has since pivoted exclusively to Pikabot.
– Recommendations include practicing vigilance with emails, regularly updating software, and implementing a multilayered security approach within organizations.
In addition, the notes provide detailed technical information about the behavior and impact of Pikabot, as well as security recommendations and Indicators of Compromise (IOCs) for further reference.
