Description (last modified by teor)

Certain accounts are vulnerable to social engineering homograph impersonation

=====

The way this works is since it's hard to distinguish between lower case "L" (l) and upper case "I" (I) in the font used for usernames, then one can make accounts on trac that impersonate other legitimate accounts by using upper case "I", such as the account that I use right now to report this issue.

There are two possible solutions for this:

  1. Change the font used for usernames on Trac with one in which lower case "L" (l) and upper case "I" (I) are visually distinguishable with our normal human eyes.
  1. Make alternate accounts for all core Tor people that substitute lower case "L" (l) with upper case "I" (I) (or permutations of them if they more than a single lower case "L"), and then change the hashed passwords in the database with something else.

I'd like that option 2 is at least made for the present account.

It is distinguishable on Windows.
Is this a real problem?

It isn't on Debian.

Also AFAIA most/many Tor folks are on Debian.

Relax. It's just a homograph.
