Using Verif圜tl, the file will either be written to the current working directory or %APPDATA%\.\LocalLow\Microsoft\CryptnetUrlCache\Content\. Review the reputation of the remote IP or domain in question. \ During triage, capture any files on disk and review. It is not entirely common for certutil.exe to contact public IP space. In addition, f (force) and split (Split embedded ASN.1 elements, and save to files) will be used. This behavior does require a URL to be passed on the command-line.

You can use bitsadmin /list /verbose to list out the jobs during investigation. In some suspicious and malicious instances, BITS jobs will be created. It’s important to review all parallel and child processes to capture any behaviors and artifacts. Note that the network connection or file modification events related will not spawn or create from bitsadmin.exe, but the artifacts will appear in a parallel process of svchost.exe with a command-line similar to svchost.exe -k netsvcs -s BITS. Typically once executed, a follow on command will be used to execute the dropped file. Review the reputation of the IP or domain used. In addition, look for download or upload on the command-line, the switches are not required to perform a transfer.
