aisuru (825591d0-dba5-4084-b9f9-3a5bc16604ef)
Aisuru is a Mirai-derivative DDoS botnet active since at least August 2024. The botnet has evolved through two distinct generations — transitioning from DNS A record C2 resolution to a DNS TXT scheme using CAFEBABE XOR-encoded IP addresses, and most recently adopting HMAC-SHA256 authentication with a new 0x1CEB00DA protocol magic.
