That BSI expected Especially on the discount days before the Christmas business, but also during the Christmas business itself, in 2021 record values for the number and severity of cyberattacks on retailers. The BSI warned Above all against DDoS attacks, in which the IT infrastructures of the retailers are overloaded with millions of accesses within a very short time and are therefore no longer accessible to the customers.
“In the past few weeks we have observed DDoS attacks with up to 21.8 million requests per second (MRPS). This corresponds to an increase of 28 percent over previously measured values,” said BSI President Arne Schönbohm. It is to be feared that these attack technologies would also be used for DDoS extortion in the high-turnover days.
The expert recommends that existing protective measures against DDoS attacks should therefore be adapted to the new capacities of cyber criminals. Cyber criminals often use infected home routers, unprotected servers and systems compromised by Trojans for DDoS attacks. (dpa / pma)
