前情提要：「Hacking Team 被黑而洩漏出來的資料」。
在「How a Russian hacker made $45,000 selling a 0-day Flash exploit to Hacking Team」這邊提到了 Hacking Team 被黑而洩漏出來的信件，透漏了俄羅斯的人賣 Flash Exploit 給 Hacking Team 的過程。
從內容就可以看出不同的賣法，包括「首次」與「獨家」都是可以談的條件：
1) The price is US$45,000.00 for the non-exclusive sale of any special discount for the "first" deal together will be greatly appreciated :)
然後有些東西是另外加密通信的：
The two men then exchanged PGP keys, which they used to exchange a number of encrypted messages, presumably one including how Toporov would like to be paid.
然後還有 invoice：
而買了幾個建立關係後，後面還會有 discount：
Now your discount on the next buy is -5k and -10k is for a third bug.
最近應該會有不少人跳下去解讀洩漏出來的資料...
