Ransom Note
  • Hi friends, Whatever who you are and what your title is, if you're reading this it means the internal infrastructure of your company is fully or partially dead, all your backups - virtual, physical - everything that we managed to reach - are completely removed. Moreover, we have taken a great amount of your corporate data prior to encryption. ATTENTION! Strictly prohibited: - Deleting files with .arika extension; - Replacing or renaming .arika and .akira files; - Using third party software to recover your systems. If you violate these rules, we cannot guarantee a successful recovery. Well, for now let's keep all the tears and resentment to ourselves and try to build a constructive dialogue. We're fully aware of what damage we caused by locking your internal sources. At the moment, you have to know: 1. Dealing with us you will save A LOT due to we are not interested in ruining you financially. We will study in depth your finance, bank & income statements, your savings, investments etc. and present our reasonable demand to you. If you have an active cyber insurance, let us know and we will guide you how to properly use it. Also, dragging out the negotiation process will lead to failing of the deal. 2. Paying us you save your TIME, MONEY, EFFORTS and be back on track within 24 hours approximately. Our decryptor works properly on any files or systems, so you will be able to check it by requesting a test decryption service from the beginning of our conversation. If you decide to recover on your own, keep in mind that you can permanently lose access to some files or accidentally corrupt them - in this case we won't be able to help. 3. The security report or the exclusive first-hand information that you will receive upon reaching an agreement is of great value, since NO full audit of your network will show you the vulnerabilities that we've managed to detect and use in order to get into, identify backup solutions and download your data. 4. As for your data, if we fail to agree, we will try to sell personal information/trade secrets/databases/source codes - generally speaking, everything that has a value on the darkmarket - to multiple threat actors at once. Then all of this will be published in our blog - akiral2iz6a7qgd3ayp3l6yub7xx2uep76idk3u2kollpj5z3z636bad[.]onion. 5. We're more than negotiable and will definitely find a way to settle this quickly and reach an agreement which will satisfy both of us. 6. Negotiations with Akira can only be conducted in a chat room, which you can access using the login details provided below or in the notes (a readme.txt file) in your systems. You should ignore any attempts (such as emails/social media messages, phone calls, etc.) to redirect you to another chat or email address (proton.me is often used by unauthorized individuals) on our behalf. 7. Be careful while working with recovery agencies as they often try to use your cyber incident to stuff their pockets. There are many risks for you to lose money and get nothing in return. If you're indeed interested in our assistance and the services we provide you can reach out to us following simple instructions: 1. Install TOR Browser to get access to our chat room - torproject[.]org/download/. 2. Paste this link - https://akiralkzxzq2dsrzsrvbr2xgbbu2wgsmxryd4csgfameg52n7efvr2id.onion/d/3583680826-DUCYH . 3. Use this code - 0074-XO-GBGV-DNLW - to log into our chat. Keep in mind that the faster you will get in touch, the less damage we cause.
