A detailed view of high severity alerts raised during the lifetime of the micro-VM helps security teams to investigate the actions of the malware so that the motivations of the attacker can be understood.Forensic evidence is capture d from the threat, including any behaviour mapped to the MITRE ATT&CK framework.When the file is closed, the micro-VM is destroy ed, along with any malware.We can see in L ive V iew that the invoice.doc file is opened in a micro-VM.Bromium Live View shows a list of active micro-VMs.Bromium Secure Platform opens each document in separate micro-VM.In this blog post, we go through the stages of its infection chain to showcase how Dridex uses five code injection techniques to masquerade itself as legitimate Windows processes (MITRE ATT&CK technique T1036 ) to avoid detection.īefore jumping into the behavio u r al analysis, we will first demonstrate the execution of this latest Dridex sample within a micro-VM and how Bromium safeguards the en d user by isolating the attack and maintaining the integrity of the system. The payload was isolated by Bromium Secure Platform and captured the malware, which helped us to analyse its infection chain and to understand how the attack worked. In July 2019 we observed a phishing campaign delivering the Dridex banking Trojan. Since the lull in Emotet activity at the beginning of June 2019 and AZORult, Dridex and ransomware campaigns have become more prominent. An incremental integer value is supplied to the command line to the suspended process to perform specific tasks. The code injection techniques were used against legitimate W indows executables.The variant uses five code injection techniques during its infection lifecycle: AtomBombing, DLL order hijacking, p rocess hollowing, PE injection and t hread execution hijacking.A new variant of Dridex observed in July 2019 masquerades as legitimate Windows system processes to avoid detection.
