Links to this blog is private now, but how fast it become public depends only from you. http://gtmx56k4hutn3ikv.onion/?dUIel0o8kfjZf4zUHDbm About the consequences that can appear in case if you won't cooperate with us to resolve this situation: -The price of your stocks will fall down and you will loose much more money than the amount we ask. -Your partners such as NATO, or Belgian Army or anyone else won't be so happy that their secret documents are in free access in the internet. Who knows how the third party can use those documents, we are not responsible for that. -GDPR will arrange the revision of your company and the outcome they figure out will make you cry, this is a fact. -Part of your systems will stay locked and you can't recover it and few years of labor of your employees become meaningless. https://temp.sh/fVAxj/1.png https://temp.sh/VZRcj/2.png https://temp.sh/qpkLy/3.png https://temp.sh/hPkTt/4.png https://temp.sh/ENvac/5.png https://temp.sh/YzAJd/6.png https://temp.sh/eBGdx/7.png https://temp.sh/KAXUW/8.png
