Amid the messages that popped up on Ukrainian phones over night was one that contained a link to a newly-created Telegram channel. The channel appears to be run by an anti-Ukrainian group which has quickly gained 15,600 subscribers and a huge amount of activity with hundreds of thousands of views of posts. The channel posted a screenshot of the alert with a derogatory caption. The hackers behind the channel also posted propaganda saying that Ukraine is "losing decisively, and you know it". The alerts themselves were also strangely flippant and not the kind of thing you imagine to be sanctioned by a professional cyber military unit. ""Hi! A nuclear alert is about to go off all across Ukraine! Don't worry, the Oreshnik is on its way." Oreshnik is the name of a Russian intermediate-range ballistic missile capable of carrying nuclear or conventional warheads. The alerts that landed on Russian phones were also written in a colloquial way with swear words. It has all the hallmarks of a hacktivism - activist hackers. Dozens of hacktivist groups have emerged on both sides since the full-scale invasion and often use loud and attention grabbing hacks to make political points. They also relish the attention. One post to the Telegram group says: "Greetings to the SBU, the Armed Forces of Ukraine, and everyone else who is reading this channel." Although hacktivists are meant to be separate from official state run hacking teams, some groups have been seen to work closely with Ukrainian or Russian militaries.
