Really curious the use of the "zoom.com" domain. However, since the endpoint uses insecure HTTP, maybe this should be a simple endpoint/hostname redirection.

A search of "router/firmware/query.aspx" leads me to D-Link endpoints who also uses the "wrpd" subdomain.

> The CronRAT adds a number of tasks to crontab with a curious date specification: 52 23 31 2 3. These lines are syntactically valid, but would generate a run time error when executed. However, this will never happen as they are scheduled to run on February 31st. Instead, the actual malware code is hidden in the task names and is constructed using several layers of compression and base64 decoding.

The actual malware uses the task name from these "never occurring crontab". The invalid date is just a kind of signature.

Fun fact: both books have precisely the same content

They just don't admit how hard did they failed in communications apps. Clearly priority and focus issues.
