According to Browsec's website this application can be used to Bypass firewalls. So in countries like Iran it seems a useful tool to bypass censorship and filtering.

For start using this application there are two version available, A "Chrome extension" and a "Portable Firefox" version.

My question is that is it safe to use Chrome extension of this software? can it cause security problem when i log in to Gmail and other password protected websites when i use this extension?

For example can this application secretly steal my passwords?

Explanation / Answer

The main risk of using a proxy solution such as Browsec or any of the TOR clients is that they push your trust from your local network neighborhood (your employer, your ISP, your government) to an unknown remote network neighborhood (Russia? Finland? Black hats? GCHQ?). The exit node effectively controls how your browser (or other client) sees the network, so a variety of code insertion attacks and monitoring become feasible. For example, the malicious exit node can substitute one page for another, a script for another, or a download for another.

This is called the untrusted network threat model. In order to mitigate such a risk, ALL traffic sent over the untrusted network needs to be authenticated and encrypted.
