Internet Protocol Security

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

Today's update on Petya
Previously, it was believed that the ransomware would not begin encrypting until an hour after the initial infection. It is now been discovered that it begins encrypting the first 1MB of the below file types upon infection. Therefore turning off your device when viewing the reboot message, will not stop encryption.

It is also now being disputed if the goal of this attack was to collect Bitcoin or cause mass destruction in the devices it infects.

Files types:
.3ds .7z .accdb .ai .asp .aspx .avhd .back .bak .c .cfg .conf .cpp .cs .ctl .dbf .disk .djvu .doc .docx .dwg .eml .fdb .gz .h .hdd .kdbx .mail .mdb .msg .nrg .ora .ost .ova .ovf .pdf .php .pmf .ppt .pptx .pst .pvi .py .pyc .rar .rtf .sln .sql .tar .vbox .vbs .vcb .vdi .vfd .vmc .vmdk .vmsd .vmx .vsdx .vsv .work .xls .xlsx .xvd .zip

To vaccinate your computer so that you are unable to get infected with the current strain of NotPetya/Petya/Petna simply create a file called perfc in the C:\Windows folder and make it read only.
