Hi Qiwi (they have a twitter account lol lets see how long it takes). We rolled up and smoked ~10.5TB of backups.
Your company has been dealt with by Network Battalion 65. We recommend you contact us if you want to survive this… You guys are super fucked.#SlavaUkraini #FCKPTN pic.twitter.com/OWI6r8hn1P
