Github cookie leakage – 1000’s of Firefox cookie information uploaded by mistake – Bare Safety

Bear in mind when folks used to add their SSH keys onto Github and comparable code sharing websites by mistake?

Two years in the past, we wrote about the truth that incautious software program builders had uploaded tons of of 1000’s of personal entry management keys, fully unintentionally, together with supply code information that they did intend to make public.

Sometimes, this form of blunder occurs as a result of Linux and Unix computer systems don’t show directories or filenames that begin with a dot character (interval, full cease, ASCII 46, hexadecimal 0x2E) by default.

It’s simple to neglect that these “hidden” information and directories exist in any respect, given that you just not often discover they’re there.

One of many super-important “hidden” directories for Unix customers is .ssh, which is often invisible.

So a plain listing itemizing may appear to be this:

$ ls -lR
.:
whole 4
drwxr-xr-x 2 lua  lua  4096 2021-11-18 20:52 lua-utils/

./lua-utils:
whole 32
-rw-r--r-- 1 lua  lua   5107 2021-11-18 20:45 args.lua
-rw-r--r-- 1 lua  lua  12384 2021-11-18 20:45 base.lua
-rw-r--r-- 1 lua  lua   4628 2021-11-18 20:45 socks5.lua

Blindly packaging all these information into an archive for importing to your favorite public repository appears fairly innocent, given that each one the information within the lua account are presupposed to be public.

However should you insist that the file itemizing utility exhibits you all information (add the choice -a for all to the ls command), together with hidden information beginning with a dot, you might need a listing tree that appears like this as a substitute:

$ ls -alR
.:
whole 28
drwxr-xr-x  4 lua  lua   4096 2021-11-18 20:46 ./
drwxr-xr-x 27 lua  lua  16384 2021-11-18 20:42 ../
drwxr-xr-x  2 lua  lua   4096 2021-11-18 20:44 .ssh/
drwxr-xr-x  2 lua  lua   4096 2021-11-18 20:52 lua-utils/

./.ssh:
whole 16
drwxr-xr-x 2 lua  lua  4096 2021-11-18 20:44 ./
drwxr-xr-x 4 lua  lua  4096 2021-11-18 20:46 ../
-r-------- 1 lua  lua    74 2021-11-18 20:45 id_rsa
-rw------- 1 lua  lua  1993 2021-11-18 20:45 known_hosts

./lua-utils:
whole 40
drwxr-xr-x 2 lua  lua   4096 2021-11-18 20:52 ./
drwxr-xr-x 4 lua  lua   4096 2021-11-18 20:46 ../
-rw-r--r-- 1 lua  lua   5107 2021-11-18 20:45 args.lua
-rw-r--r-- 1 lua  lua  12384 2021-11-18 20:45 base.lua
-rw-r--r-- 1 lua  lua   4628 2021-11-18 20:45 socks5.lua

As you’ll be able to see, the complete listing tree features a hidden .ssh listing that features a file referred to as id_rsa, which is a non-public key file sometimes containing the login credentials for a number of on-line servers that you just hook up with frequently:


$ cat .ssh/id_rsa 
-----BEGIN RSA PRIVATE KEY-----

[. . . .]

-----END RSA PRIVATE KEY-----
