Shorter Attacks More ‘Prevalent,’ But That’s Changing
These shorter, multivector attacks “remain prevalent,” the Azure DDoS Protection team says. However, more attacks are starting to last longer.
“As with the first half of 2021, most attacks were short-lived, although, in the second half of 2021, the proportion of attacks that were 30 minutes or less dropped from 74% to 57%,” the team says. “We saw a rise in attacks that lasted longer than an hour, with the composition more than doubling from 13% to 27%. Multi-vector attacks continue to remain prevalent.”
Regarding the longer attacks, end users tend to experience those as multiple short, repeated bursts, Microsoft says.
