Russia's Yandex says it repelled biggest DDoS attack in history
MOSCOW – A cyber attack on Russian tech giant Yandex’s
servers in August and September was the largest known distributed
denial-of-service (DDoS) attack in the history of the internet, the company
said on Thursday.
The DDoS attack, in which hackers try to flood a network
with unusually high volumes of data traffic in order to paralyse it when it can
no longer cope with the scale of data requested, began in August and reached a
record level on Sept. 5.
“Our experts did manage to repel a record attack of nearly
22 million requests per second (RPS). This is the biggest known attack in the
history of the internet,” Yandex said in a statement.
Yandex said it had seen 5.2 million RPS on Aug. 7, 6.5
million RPS on Aug. 9, 9.6 million RPS on Aug. 29, 10.9 million RPS on Aug. 31
and finally 21.8 million RPS on Sept. 5.
U.S. cybersecurity firm Cloudflare, which is widely used by
businesses and other organisations to help defend against DDoS attacks, said in
August the largest DDoS attack it was aware of reached 17.2 million RPS earlier
this year.
Cloudflare could not immediately be reached for comment on
Thursday.
