Prevent SMS flooding
On Sunday 18th August
a malicious user began flooding our SMS system with a new request every 4 seconds. We need to introduce threshold for how many times we will send out SMS messages to a single number each day.
Proposed solution
Implement the RateLimits\KeyValueLimiter
to the sms sender service. If the key (hashed phone number) exists and is over the threshold do not allow to be sent.
Limits
10 per day?
