Some trends in DDoS attacks include increased attack
complexity, power, and duration, more frequent targeting of government
agencies, increasing use of bots and botnets, and more ultrashort attacks.
Attacks are becoming more complex and multi-vectored, with attackers targeting
a victim's key functions and conducting combined attacks along different
vectors. The number of ultrashort attacks and average attack power are
increasing, and government agencies are becoming frequent targets of DDoS
attacks. Bots and botnets have become the most common vectors for DDoS attacks,
while HTTP flood attacks are also widely used.
