Do not try to decrypt your data using third party software - it may cause permanent data loss. We are always ready to cooperate and find the best way to solve your problem. The faster you write - the more favorable conditions will be for you. Our company values its reputation. We give all guarantees of your files decryption. What are your recommendations? - Never change the name of the files, if you want to manipulate the files, be sure to back them up. If there are any problems with the files, we are not responsible for them. - Never work with intermediary companies because they charge you more money.Don't be afraid of us, just email us. Sensitive data on your system was DOWNLOADED. If you DON'T WANT your sensitive data to be PUBLISHED you have to act quickly. Data includes: - Employees personal data, CVs, DL, SSN. - Complete network map including credentials for local and remote services. - Private financial information including: clients data, bills, budgets, annual reports, bank statements. - Manufacturing documents including: datagrams, schemas, drawings in solidworks format - And more... What are the dangers of leaking your company's data. First of all, you will receive fines from the government such as the GDRP and many others, you can be sued by customers of your firm for leaking information that was confidential. Your leaked data will be used by all the hackers on the planet for various unpleasant things. For example, social engineering, your employees' personal data can be used to re-infiltrate your company. Bank details and passports can be used to create bank accounts and online wallets through which criminal money will be laundered. On another vacation trip, you will have to explain to the FBI where you got millions of dollars worth of stolen cryptocurrency transferred through your accounts on cryptocurrency exchanges. Your personal information could be used to make loans or buy appliances. You would later have to prove in court that it wasn't you who took out the loan and pay off someone else's loan. Your competitors may use the stolen information to steal technology or to improve their processes, your working methods, suppliers, investors, sponsors, employees, it will all be in the public domain. You won't be happy if your competitors lure your employees to other firms offering better wages, will you? Your competitors will use your information against you. For example, look for tax violations in the financial documents or any other violations, so you have to close your firm. According to statistics, two thirds of small and medium-sized companies close within half a year after a data breach. You will have to find and fix the vulnerabilities in your network, work with the customers affected by data leaks. All of these are very costly procedures that can exceed the cost of a ransomware buyout by a factor of hundreds. It's much easier, cheaper and faster to pay us the ransom. Well and most importantly, you will suffer a reputational loss, you have been building your company for many years, and now your reputation will be destroyed. Do not go to the police or FBI for help and do not tell anyone that we attacked you. They won't help and will only make your situation worse. In 7 years not a single member of our group has been caught by the police, we are top-notch hackers and never leave a trace of crime. The police will try to stop you from paying the ransom in any way they can. The first thing they will tell you is that there is no guarantee to decrypt your files and delete the stolen files, this is not true, we can do a test decryption before payment and your data will be guaranteed to be deleted because it is a matter of our reputation, we make hundreds of millions of dollars and we are not going to lose income because of your files. It is very beneficial for the police and the FBI to let everyone on the planet know about the leak of your data, because then your state will receive fines under GDPR and other similar laws. The fines will go to fund the police and FBI. The police and FBI will not be able to stop lawsuits from your customers for leaking personal and private information. The police and FBI will not protect you from repeat attacks. Paying us a ransom is much cheaper and more profitable than paying fines and legal fees. If you do not pay the ransom, we will attack your company again in the future.
