Java反序列化漏洞被忽略的大规模杀伤利用

前一段时间热炒的Java反序列化漏洞,大家在玩的很嗨的时候貌似忽略了一件很重要的事情——Java在cs架构的设计中使用序列化传输是非常普遍的现象,而在像JBoss这种中间件也使用这种设计。所以,我在一边研究这个漏洞,一边看大家嗨嗨的玩的同时,也很好奇在一些通过Java实现的CS架构应用(比如:大型国企都喜欢用的会计软件、内容发布系统),是不是也会用到Apache Commons Collections这个库。

Fareit Trojan Analysis and Prevention

On November 5, 2015, NSFOCUS Threat Analysis Center (TAC) intercepted an unknown virus targeting a bank and then named it Fareit trojan after sample analysis. Attackers could exploit Fareit trojan to compromise the target host by sending spam to trick users into clicking an .exe file, thereby stealing website information and passwords stored on the FTP client.

Fareit木马分析与防护

11月5日,绿盟威胁分析系统TAC在某行截获未知病毒样本,随即进行样本分析,后续该病毒被命名为Fareit木马。Fareit木马,主要是通过发送垃圾邮件,骗取用户点击运行exe文件来入侵目标主机,进而窃取FTP客户端保存的站点信息与用户密码。

本文对该木马的执行过程及行为进行了详细分析,并从执行检测、网络防护、终端防护等方面给出方法及整体解决方案。文章中呈现的分析过程较为详细,可以成为木马分析的实操手册,并可以为类似的信息窃取类木马分析及防护提供经验借鉴。

An Analysis of the vBulletin 5.x Remote Code Execution Exploit

vBulletin is a commercial Internet forum software package, boasting tens of thousands of users which are growing rapidly worldwide. It is written in the PHP web language and uses the MySQL database. Owing to its large user base, vBulletin is frequently reported to have vulnerabilities. In NSFOCUS Vulnerability Database (NSVD), there are 49 entries related to vBulletin, most of which are SQL injection vulnerabilities. The vulnerability disclosed this time is of a relatively high risk level, known as remote code execution (RCE). Theoretically, an attacker can exploit this vulnerability to execute arbitrary code or even take complete control of a forum that uses this program.

vBulletin5远程代码执行漏洞分析

vBulletin 是一个商用的论坛程序套件,在全球拥有数万用户且增长速度很快。该论坛采用PHP Web语言及MySQL数据库。正是由于其用户较多,其漏洞出现频率较高,在绿盟科技漏洞库(NSVD)中共有[49条记录][1],大部分是SQL注入漏洞。此次漏洞等级较高,为远程代码执行漏洞(RCE),理论上说攻击者可执行任意代码,甚至完全控制论坛 。

Attack Chain-based Threat Aware System

With the network threat forms becoming more and more diversified and complex and challenges from advanced persistent threat (APT) attacks, new-generation threats spread more quickly on a larger scale, covering mobile devices, desktops, networks, web, applications, and social networks. In the new normal situation, it is far from enough for customers to obtain threat information only from traditional network intrusion prevention system (NIPS) and network intrusion detection system (NIDS) devices, and professional, systematical, and intelligent devices are becoming really crucial. In particular, with the development of the Internet and improvement of user experience requirements, network threat behaviors should be detected through big data analysis to show customers the entire dynamic attack process intuitively.

什么是Xcode

Xcode 是苹果公司开发的编程软件,是开发人员进行苹果电脑及手机程序开发的工具。根据斯诺登提供的资料,美国政府研究人员创建了一个特殊版本的Xcode,希望借此将监控后门植入到手机应用程序APP中,并通过苹果应用商店App Store散发。(该信息引自百度百科等词条)
