Kyiv Independent Says Attackers Hijacked Newsletter to Send Fake Nuclear Warning
Summary
The Kyiv Independent says attackers accessed its CMS and newsletter service to send four fake emails and post messages. The outlet suspects a Russian operation but says no group has claimed responsibility and has not released technical evidence.
Key points
- The Kyiv Independent reported that attackers accessed its content management system and a newsletter service.
- Four emails in Russian and English falsely claimed that President Volodymyr Zelensky had launched a nuclear warhead at Kyiv; attackers also posted similar messages on the outlet’s website.
- The outlet suspects a Russian operation based on the messages, but no group has claimed the attack and no technical evidence has been published.
- It remains unknown how access was gained, which newsletter service was involved, how many recipients received the emails, or whether attackers could access or copy the subscriber list.
- The outlet said members’ and donors’ payment details were not at risk because a third-party provider handles payment and banking information.
