Monobank, a Ukrainian digital bank, is facing an unprecedented DDoS attack that has now lasted for three days, said the bank’s co-founder Oleh Gorokhovsky.

The scale of the attack has reached over 5.5 billion requests and caught the attention of Amazon Web Services (AWS).

“AWS employees have joined the case. A cyberattack of this magnitude is also atypical for them,” Gorochowski wrote.

The co-founder said the situation was under control, but the scale was “impressive.”

The attack began on Friday, August 16, when the bank received one billion requests in just three hours. As the cyberattack continued into its third day, Ukrainian intelligence services offered help in repelling the attack.

Despite the ongoing attack, Gorokhovsky assured that the situation was under control. However, he stressed the extraordinary scale of the cyber offensive, which led to the involvement of national security services and international technology giants.

The incident underscores the increasing complexity and scale of cyber threats facing financial institutions during Russia’s war in Ukraine, even when they employ sophisticated defenses.
