Rewterz Threat Alert – GrandCrab and Ursnif Campaign Observed in the Wild

January 29, 2019

SEVERITY: Medium

 

 

CATEGORY: Phishing

 

 

ANALYSIS SUMMARY 

 

 

A campaign distributing both Ursnif malware and GrandCrab ransomware via malicious Word documents attached to phishing emails. The Word documents contained a VBS macro that executes a base64 encoded PowerShell script. The PowerShell script is used to retrieve the files associated with the GrandCrab and Ursnif infections. The first payload that is downloaded and executed is a PowerShell command used to download an additional PowerShell script. This additional PowerShell script contains a base64 encoded PE file which it injects into memory for execution. This PE file was identified to be a variant of the GrandCrab ransomware. The second payload that is download and executed via the VBS macro is the Ursnif executable, which is used for malicious activities such as gathering system information and harvesting credentials.
