Aisuru Botnet Fires 15.72 Tbps DDoS at Microsoft Azure

⚠️ Microsoft reported that the Aisuru botnet launched a massive DDoS attack against a public Azure IP in Australia, peaking at 15.72 Tbps and nearly 3.64 billion packets per second. The traffic originated from over 500,000 IP addresses and consisted of extremely high-rate UDP floods with minimal source spoofing. Microsoft noted the bursts used random source ports, which aided traceback and provider enforcement. Azure's mitigations absorbed the attack without a reported widespread outage.

Cloudflare Removes Aisuru Botnet Domains from Rankings

🛡️ Cloudflare has begun redacting and hiding domains tied to the rapidly growing Aisuru botnet after those malicious hostnames repeatedly appeared atop its public domain rankings. The botnet — comprised of hundreds of thousands of compromised IoT devices — recently shifted from querying 8.8.8.8 to 1.1.1.1, flooding Cloudflare’s resolver and skewing popularity metrics. Cloudflare says attackers are likely both manipulating rankings and mounting attacks on its DNS service, and the company is refining its ranking algorithm while removing known malicious entries.

Aisuru Botnet Evolves from DDoS to Residential Proxies

🛡️ Aisuru, first identified in August 2024, has been retooled from launching record DDoS assaults to renting hundreds of thousands of compromised IoT devices as residential proxies. Researchers warn the change powers a massive proxy market that is being used to anonymize large-scale content scraping for AI training and other abuses. The botnet — roughly 700,000 devices strong — previously produced multi‑terabit attacks that disrupted ISPs and damaged router hardware. Industry and law enforcement are sharing blocklists and probing proxy reseller ecosystems tied to the infections.
