Rewterz Threat Alert – Trickbot delivered via Covid 19 Phishing Emails
April 20, 2020Rewterz Threat Alert – CoronaVirus Update App Leads to Spying on Users
April 20, 2020
Severity
Medium
Analysis Summary
HawkEye, primarily an infostealer, has additional capabilities such as bypassing of AV systems and keylogging. A spear phishing campaign is detected using malicious RTF documents sent via corona-themed emails to distribute the HawkEye keylogger. While most malicious RTF documents use exploits to trigger Object Linking and Embedding (OLE) calls, in this case the documents use the \objupdate switch. A victim would need to enable macros for the infection process to begin. The embedded OLE objects, five of them in this case, appear to be macro-enabled Excel sheets. PowerShell is used to execute .NET code which downloads and executes the Hawkeye payload.
As suspected, while opening the Word document, the Excel sheet embedded within the document was loaded and immediately displayed a notification to enable the macro. The macro notification will popup multiple times even though the user closes the notification or clicks the disable button.
