最近突发奇想,想对所掌握的python知识进行总结一下,目前其实还停留在python层面如何使用,还没有深入到虚拟机部分,如果下面有哪些错误,欢迎指出。
OJ(Online judge, 在线编程测评提交代码到后台运行检查)网站一般都允许各种各样的代码提交,其中很有可能包含python3,于是决定尝试通过python3的代码执行,进行沙箱逃逸,以及绕过各种限制。
我随便找了一个OJ网站,这个站点的python3有如下限制

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August
This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.
