Security News > 2023 > June > Japanese pharma giant Eisai discloses ransomware attack
Pharmaceutical company Eisai has disclosed it suffered a ransomware incident that impacted its operations, admitting that attackers encrypted some of its servers.
Eisai is a Tokyo-based pharmaceutical company with an annual revenue of $5.3 billion and over 10,000 employees.
In a notification posted to their website, Eisai disclosed that they suffered a ransomware attack over the weekend, a typical time for attackers to deploy encryptors as IT teams are understaffed and unable to respond effectively to the rapidly evolving situation.
"A ransomware incident that encrypted some of Eisai Group's servers was detected late at night on Saturday, June 3, Japan time," reads the notice.
Eisai had fallen victim to another cyberattack in December 2021 by a now-defunct ransomware group named 'AtomSilo.
Although AtomSilo's extortion portal isn't online anymore, the data the threat group leaked on it included several MDF and LDF database dumps it allegedly stole from Eisai's network.
