High Load DDoS Attack - Blog2020-02-01
This might just be another botnet looking to gather more followers into the herd, or it might be a directed attack against SIXTEENmm.
- There's about 10,000 requests/second hitting HTTP endpoints
- Most attacks are trying to hit the search page with a payload.
- Somebody seems to believe there's an RCE in our search engine. We cannot currently confirm that, even using the series of attacks that are hitting.
- There is no reason to believe there is an RCE. This attack seems to be searching for one.
- Attacks are coming from three different VPS groups.
