不过等有空的时候还是应该多写些东西吧。

短短半年时间，比特币的价值已经翻了十几倍。而比特币的挖掘难度也在不断上升。比特币的快速崛起，迅速催生出新的网络犯罪。

这个事情还要从八月份拦截到的一个恶意软件说起。八月上旬，我们收到用户报告的一个伪装成COMODO AntiVirus的恶意软件。在一台测试机上感染过这个恶意软件后，它会源源不断的下载各种文件。两个小时它下载了将近300M的文件，其中包括ATI和NVDIA的显卡驱动。恶意软件本身没有什么特别的，但是它下载的这些文件让人觉得摸不着头脑。经过对下载文件的仔细分析，我们发现这可能是一种新的犯罪手段。

比特币需要用大量运算来“挖掘（mining）”。通常情况下，比特币的矿工（miner）会在自己的计算机上安装挖掘软件来做大量的运算，以获取比特币。这种大规模的运算通常使用使用CPU或者用GPU来运算。尤其使用GPU来运算的矿工很多，这是因为GPU运算速度比CPU快很多倍。通常矿工们都会去买一块或者多块高性能的独立显卡，利用NVDIA的SLI技术或者ATI的Crossfire技术，再配合相应的驱动程序以及挖掘软件来进行大规模运算。这样就可以以时间+金钱为代价可以换来高额的利润。这里提到金钱是因为两部分，一是高性能的计算机的采购费用，二是高性能带来的能源消耗（说白了就是电费）。

那些恶意软件的制造者们很快就盯上了这一块肥肉。利用免费的显卡SDK，开源的挖矿客户端源码，外加各种木马技术，制造了这种恶意软件：当你的机器被感染的时候，你的硬件资源就成了他们窃取的目标。它们会在你机器上安装上适用的显卡驱动，并且安装挖掘比特币的客户端，将运算的结果源源不断的通过网络发送回恶意软件制造者们的服务器，也就是他们的比特币钱包。利用这种方法，恶意软件的制造者们让数以万计的计算机成为他们赚钱的工具。

分布式大规模运算，这并不是第一天出现。1999年发布的SETI@home是最著名的分布式大规模运算的典范。我们这里提到的，利用木马病毒的方式窃取硬件资源为犯罪分子牟利，这是最近才出现的，由比特币的流行快速催生出来的产物。

马克思曾经说过：“如果有100%的利润，资本家们会挺而走险；如果有200%的利润，资本家们会藐视法律；如果有300%的利润，那么资本家们便会践踏世间的一切”。在高额的利润的诱惑下和很低的技术门槛的情况下，这些恶意软件的制造者们铤而走险的去制造了这些危害网络用户的恶意软件。

作为安全行业的一员，我们唯一能够做的是进一步改进自己的产品，为用户提供更好的防护。让用户的财产和隐私得到充分的保护。Creating Trust Online，这是我们的目标。

工作上依然很忙。手上的产品很多，人的精力有限，无法完全顾及到。可是对于我这种性格，要么不做，要么就做最好。时间和精力只能从个人时间中挤出来。每天除了在公司处理日常事物，晚上还要继续工作。所以一直感到很疲惫。但是做自己喜欢的事情，总是快乐的。

前一段时间公司发生很多事情，虽然可能和我有关系。但是我实在不想去管。我不是懒，我实在是不想把精力放到与项目无关的事情上。说实话，在这家公司待了快4年，什么事情都遇到过了。现在遇到的问题我根本都没放在心上。

我总是和属下进行“人生相谈”。内容主要是如何在为公司创造价值的同时体现自己的个人价值。这其实是一个很深奥的话题。每个人的生活目标不同。如果不用传销洗脑的方法，想统一每个人的思想是很难的。我最多的是拿我自己的想法和目标和大家谈。我也想给大家树立一个榜样——从做好每件事开始。

生活方面嘛，没什么好说的。因为属于我自己的个人时间真的是很少。每天还是有背着相机包，里面都会放上一个单电。单反好久没带出门了。夏天周末太热，实在不想背着几斤重的相机出门。唉。偶尔也会有比较满意的照片。希望等有空的时候把拍的很多很多照片整理一下，然后传到Flicker。

随便写了几句就一点了。
下次在写好了，贴几张最近拍的照片。

这就是全部吧。

“The role of a manager should be to ensure that those that work for him/her eventually leave and go onto bigger and better things” Mark Plant

If you are unhappy in your job – leave and if you aren’t excited about work every morning – stop whatever you’re doing and do something else.

This is what we need to live by.

If you aren’t being challenged in your job – leave.

If you are cruising in your current work – leave.

If you aren’t sweating it at present and feeling under pressure – leave.

If you think you understand everything that you are doing where you are currently working – leave.

If you aren’t failing enough – leave and go find somewhere where you fail before you succeed. When you find yourself succeeding too often – leave again.

If you think you are successful – leave and find something or somewhere where you aren’t. When you become successful again – leave again.

If everyone likes you and wants to work with you – leave and go work somewhere where they don’t (and then get them to want to).

If your work is winning awards and it feels like you win most pitches – leave and go somewhere where no one has won anything and there is a low rate of success at pitches. Help them turn it around.

If you think you know a product inside out – leave and go find a product that you don’t.

If you think you understand the value of all your influences and feel that you have challenged them from all the directions you can find – leave and go find somewhere where there are different (or unheard of) influences that maybe you don’t even understand why they are influences.

If your manager is not influencing you to ultimately leave and go onto bigger and better things – leave.

If someone is standing in the way of your progress (either internally or externally) – leave.

If someone is trying to make you stay in your job – leave.

If your manager is trying to make you stay, they aren’t a good manager – leave.

If the days go too smoothly and there is too much time for idle chatter (or you are surrounded by people with too much time for idle chatter) – leave.

If you don’t work with people who put the same amount of thought and effort into teamwork and collaboration as you do – leave and find people who do.

If there is a culture of persuading people to stay in their jobs by offering them more money – leave.

If where you work there is a business culture of holding on to people to prevent them working for competitors – leave.

If where you work there is a business culture of trying to make competitors fail – leave.

If there isn’t a culture (or understanding) of creating working relationships between the right people and that not everyone works well together – leave.

And if in this work culture there is not the understanding that a certain degree of tension between these great working relationships produces greater work – leave.
