Ukraine’s national postal service Ukrposhta was hit by a cyberattack last week after the sales of a stamp depicting the famous exchange on Snake Island between the Russian armed forces and the Ukrainian boarder guards went online.
The island was hit by Russian missile strikes after the Ukrainian defenders refused to surrender and responded to the threat with the words: “Russian warship, go f*** yourself,” a phrase which has become a popular Ukrainian slogan used to show defiance.
Ihor Smilianskyi, Ukrposhta's CEO, issued an apology to customers for what he called a DDoS attacks but did not reveal who might be behind it.
“We are really doing everything, together with internet providers, to restore both the online store and other Ukrposhta systems that are also temporarily not working due to a DDoS attack on our systems,” Smilianskyi wrote on Facebook.
The stamp went for sale just two days before Moskva, the flagship of Russia’s Black Sea fleet involved in Snake Island attack sank after it was struck with Ukrainian-made Neptune missiles.
Ukraine said this month it thwarted an attempt by Russian hackers to damage its electricity grid with a cyberattack.
