微软去年下半年才有bounty program吧，扣的跟三孙子似的，能买几个0day。
很多都是
安全公司或者独立研究人员报的，今年一月份奇虎就报了70个，不要觉得搞黑产的人在
看到微软patch之前不知道怎么找漏洞。这些安全公司报的一部分就是他们系统抓的
0day。

full disclosure这么多年也没见fbi派人去抓，更别说不在你本土的雷锋了。当然早就
流行no free bugs运动了。人一个好用的exp能卖60万，干嘛要免费放。

: 现在不说没有雷锋愿意免费释放值钱的0day，就算有，FBI也会让他在监狱安度晚年。

那是免费放的东西都不值钱，还不够抓人的经费。不过作为闭源的好处就是，代码安全
是次要的，首先是社会工程安全。

OpenSSL这种补bug机制，就等于免费放一个大礼包然后让全球hacker狂欢48小时。

就是时间差的问题。

MS官方Patch一出来，全世界的网管都装上了，你花了3天逆向出一个工具也搞不到什么
有价值信息。

OpenSSL的补丁一出来，工具几小时就搞定，这时候IT部门还在rebuild代码呢。

: 抓人的经费什么时候和放的东西的价值联系上了？
: 这种和patch出来后做binary code diff有什么太大的区别?

CKA Simulator Kubernetes 1.22

  https://killer.sh Pre Setup Once you've gained access to your terminal it might be wise to spend ~1 minute to setup your environment. You could set these: alias k = kubectl                         # will already be pre-configured export do = "--dry-run=client -o yaml"     # k get pod x $do export now = "--force --grace-period 0"   # k delete pod x $now Vim To make vim use 2 spaces for a tab edit ~/.vimrc to contain: set tabstop=2 set expandtab set shiftwidth=2 More setup suggestions are in the tips section .     Question 1 | Contexts Task weight: 1%   You have access to multiple clusters from your main terminal through kubectl contexts. Write all those context names into /opt/course/1/contexts . Next write a command to display the current context into /opt/course/1/context_default_kubectl.sh , the command should use kubectl . Finally write a second command doing the same thing into /opt/course/1/context_default_no_kubectl.sh , but without the use of k
