And in address line of firefox I typed in “file:///home/VM-Konto/”. > So, do you mean, that the other directories are created temporary by firefox? If yes, where can I find the temporary file system? I have started firefox with “Firefox.profile”. Quote: “Note: Only ~/Downloads and ~/.mozilla directories are real, all other directories are created by Firefox.” Just trying to understand the default “Firefox.profile”: The video from the beginning of the article describes a full hacking session from the perspective of an attacker, and how the Mandatory Access Control, seccomp-bpf, and a combination of network namespace and netfilter firewall can be used to prevent further escalation. The way to deal with this situations is described in Network/Incognito setup below. After failing a regular ransomware since only Downloads directory is present, and after failing to rise privileges and become root, the attacker will most likely try to exploit servers running on the local network. The local network attacks are mostly happening in enterprise settings.
With all these kernel layers upon layers in place, it is hard to tell in a real scenario which layer triggered first and stopped the exploit. If available, we also start AppArmor on top of everything. A number of other kernel technologies are layered on top of them, such as capability sets, a user namespace without the root user, and mounting partitions and directories using nosuid flag. These are two Linux kernel technologies specifically designed for this purpose. Privilege escalations are handled mainly by seccomp-bpf and nonewprivs.
