From Blackberry: Log4U, Shell4Me

The BlackBerry Research & Intelligence and Incident Response (IR) teams have found evidence correlating attacks by the Initial Access Broker (IAB) group Prophet Spider with exploitation of the Log4j vulnerability in VMware Horizon. This article highlights the recent indicators of compromise (IoCs) that we’ve observed.

Defenders concerned that they may have been a victim of these attacks can make use of these IoCs and detection methods to identify evidence of compromise within their environment.
