This article told me little to nothing, so I went looking and bleeping computer says it they aren’t listing the devices for security reasons. Guessing hikivision or dahua oem but who knows.

Quotes from this article:

“Akamai’s Security Intelligence Response Team (SIRT) first discovered the botnet in October 2023, noticing unusual activity on a rarely used TCP port targeting their honeypots.”

And

“targeted devices were linked to a specific NVR manufacturer, not named in the report for security reasons”
