1 million RPS DDoS attack to Russian bank

16 November, 2023 | Miscelanea

Sberbank, a major Russian financial institution, recently disclosed that it encountered an exceptionally potent distributed denial of service (DDoS) attack, marking it as the most formidable in recent history, according to a press release.

Procedure

The attack was reported to peak at one million requests per second (RPS), a magnitude approximately four times larger than any previous DDoS incidents experienced by Sberbank.
Recently, the bank, which is predominantly state-owned and holds a significant share of Russia’s assets, faced international impediments and sanctions following the conflict between Russia and Ukraine. This led to multiple cyber assaults orchestrated by hacktivists aligned with Western interests.

Comparison to similar and previous attacks

While the impact of one million RPS is substantial, it pales in comparison to record-breaking DDoS attacks utilizing the innovative ‘HTTP/2 Rapid Reset’ technique, capable of generating impacts a hundred times greater than Sberbank’s recent encounter.
Sberbank had previously announced unprecedented hacker attacks in May 2022, involving massive DDoS waves targeting its online customer services. The bank successfully repelled a DDoS attack measuring 450GB/sec, generated by a botnet comprising more than 25,000 compromised devices.
