- ======================================================== What happened? ======================================================== Greetings, JM Bozeman Enterprises! Your IT infrastructure has been compromised. All your data has been exfiltrated, encrypted, and infected, and will be analyzed using our proprietary artificial intelligence model, trained to identify the most sensitive information. All your computers are now infected with file-infecting software that will re-initiate encryption every time new data is created on your machines. This is a novel technique, and you can take pride in being the first in history to encounter it. ======================================================== What can you do? ======================================================== Options are limited. One option is to attempt restoration on your own, but you will face significant obstacles during this process while the file infector remains active in the network. Additionally, you will have to deal with the publication of a blog post containing your data, analyzed by our AI. This will include a useful breakdown of sensitive data that can be utilized by other threat actors, both cyber and physical. This is particularly critical given the fact that you are a logistics company. ======================================================== How can you be sure that we are trustworthy? ======================================================== Simply communicate with us, and you will understand the situation. You may also request a list of the downloaded data that is currently being analyzed. ======================================================== How to contact us? ======================================================== To get in touch with us, you can use the links below. - https://secp0-support.cfd/040da5/f41ffce77ac6fa80e6189640 - http://bhn2xz5jer2xeibxjzhgfp7qclttnbvkkvd4hvlmjbnz66jxq7yzn6ad.onion/040da5/f41ffce77ac6fa80e6189640 - http://2a6w667vebiebciji7vm3vj43svegvozoqypttdgojzgdcbnfsu5wiid.onion/040da5/f41ffce77ac6fa80e6189640 To access the onion link, you'll need to download and install the Tor Browser (https://www.torproject.org/download). ======================================================== How do we differ from average ransomware actors? ======================================================== You may be advised by recovery companies not to make contact with us. Usually, data publication is not considered highly dangerous for a company because it is impossible to download all data due to Tor network outages and slowdowns. However, that is not the case with us. We will provide a special breakdown of your company using our AI analysis tool on our data leakage website. This site is designed specifically to operate over TOR without slowdowns, featuring a useful file browser that provides contents in real-time without delay, eliminating the need to download useless data. You can view this using the links below in the OUR BLOG section, featuring different companies on which we have tested our AI. Furthermore, as we have stated, this is the first time in history that file-infecting software has been used for persistence. Usually, it is simple to roll back backups and resolve the issue; however, in this case, the persistence is very deep. We possess a special cryptographically signed file that can switch the infection off, along with a special cure utility that can clean all your infected files, stopping the persistent re-encryption of your data. You can go to the media and become famous, just like the first victims of the so-called 'Big Game Hunting' ransomware groups. However, do you actually need it? ======================================================== Out blog ======================================================== - https://secp0-news.ws - http://secponewsxgrlnirowclps2kllzaotaf5w2bsvktdnz4qhjr2jnwvvyd.onion To access the onion link, you'll need to download and install the Tor Browser (https://www.torproject.org/download). ---BELOW IS TECHNICAL INFORMATION REQUIRED FOR US TO PROVIDE YOU WITH DECRYPTION TOOL, DO NOT REDACT--- data_begin 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 data_end ---FINISH---
