Extortion or ransom DDoS attacks started to become a new threat in August 2020 and grew bigger and more complex since then.

One of the largest DDoS attacks that Cloudflare mitigated lasted for 60 seconds and came from a botnet with 15,000 systems that hurled close to 2Tbps of junk packets at a customer.

While this is not the largest DDoS attack recorded to date, "Terabit-strong attacks are becoming the norm," Cloudflare says.

The SNMP protocol has seen a dramatic spike of almost 6,000% from one quarter to another, although UDP-based DDoS attacks were the second most used vector.

"When we look at emerging attack vectors - which helps us understand what new vectors attackers are deploying to launch attacks - we observe a massive spike in SNMP, MSSQL, and generic UDP-based DDoS attacks" - Cloudflare.

Companies dealing with short-lived DDoS attacks, which are more frequent, should turn to an automated mitigation solution because it acts on the spot and stops the assault on the spot.
