n April, VMware patched a vulnerability CVE-2022-22954. It causes server-side template injection because of the lack of sanitization on parameters “deviceUdid” and “devicetype”. It allows attackers to inject a payload and achieve remote code execution on VMware Workspace ONE Access and Identity Manager. FortiGuard Labs published Threat Signal Report about it and also developed IPS signature in April.

In June 2022, FortiGuard Labs encountered IoT malware samples with SSH-related strings, something not often seen in other IoT threat campaigns. What piqued our interest more was the size of the code referencing these strings in relation to the code used for DDoS attacks, which usually comprises most of the code in other variants.
