Zombie bots clog internal networks

October 9, 2005

I noticed one post at The register on internal threats from Zombie bots.

Most of these “internal attackers” are likely unsuspecting victims themselves, unwitting hosts to malware infections that turn their Windows PCs into zombie drones under the control of hackers. An infected subscriber often reports performance degradations and other problems to the help desk, oblivious to the real reason why their computer seems sluggish or is behaving strangely. All the while his (it’s nearly always blokes who get their machine infected by viruses) machine is searching for other vulnerable hosts.

At China,  more and more enterprise IT managers have recognized the importance of internal threats protection and been investing on internal audit and controls. No doubt, protection the border itself, generally speaking, refering to the internet connection point, is not enough to most of large enterprise networks, let alone telecom operation networks.


P2P Definition (Chinese)

October 9, 2005

P2P的定义有很多,通过”define p2p”在google查到的是在Wiki上的定义是:

Peer-to-peer, 简称P2P,对等互联网络技术,点对点网络技术,点对点文件共享交换,深度搜索、分布计算。

Lijinshui的blog上面,有很详细的解释,引用一段:

如果回顾一下,我们会发现在WWW出现伊始P2P就是互联网的本质特征之一。人们各自建立网页、互相做链接, 人们上网是沿着链接冲浪。那时的web是真正的“网”(web)。但是当Yahoo!和Lycos建立了搜索引擎和门户站点后,人们上网的方式被改变了, 人们从此到一个地方去获取所有的信息。记得新浪曾经有一段时间说它们是“目标站点”模式,但是如果多问一句,现在人们一条一条地阅读新浪的新闻,在头脑中 还有一个“网”的概念吗?最大的问题是,这些站点控制了信息的流动、充斥了过时的信息、阻碍了真正的交流,或者对于很多人来说,另外还有太多的广告。 P2P就是把控制权重新还到用户手中去。人们通过P2P可以共享硬盘上的文件、目录甚至整个硬盘。这种能量是非常令人激动的,那些费心存储在自己的硬盘上 的东西肯定是我们认为最有价值,所有人都共享了他们认为最有价值的东西,这将使互联网上信息的价值得到极大的提升。

另外一篇文章中还提到了Intel和IBM对P2P的定义:

目 前,业界对P2P的定义还没有一个标准的说法,Intel 将P2P计算定义为“通过系统间的直接交换所达成的计算机资源与信息的共享”,这些资源与服务包括信息交换、处理器时钟、缓存和磁盘空间等;IBM则给 P2P赋予更广阔的定义,把它看成是由若干互联协作的计算机构成的系统并具备如下若干特性之一:系统依存于边缘化(非中央式服务器)设备的主动协作,每个 成员直接从其他成员而不是从服务器的参与中受益;系统中成员同时扮演服务器与客户端的角色;系统应用的用户能够意识到彼此的存在构成一个虚拟或实际的群 体。


Encrypt your GTalk with Stunnel

October 9, 2005

By accident I read the post by TombKeeper on how to Encrypt your Gtalk with stunnel. Because it’s in Chinese. Here i try to interpret a bit on his findings.

GTalk is an interesting IM/VoIP client by GOOGLE. It uses Jabber protocol, an open – source framework for P2P communications. Out of box GT doesn’t support encryption of its traffic. However, Tombkeeper found it could support encryption when you use GAIM client to communicate with GTalk server. So he found the way using stunnel to encrypt GTalk. What he did is as the following steps:

1 insert one line at the file : %SyetemRoot%/system32/drivers/etc/hosts:

127.0.0.1 talk.google.com

2 insert the following at stunnel.conf:

[Google Talk]
accept = 127.0.0.1:5222
connect = talk.google.com:5223

3 and then reboot the Stunnel, followed by start of google talk.
