Microsoft Windows And Remote Procedure Call ( Rpc ) Facilities

Which tool and application were used to exploit the identified vulnerability on the targeted Microsoft® Windows 2003 XP server?

Utilizing two simple command switches, -O and -v, provided a wealth of information about the host system. Most notably, it listed all of the open ports, protocols, and the operating system of the target system. This quick gathering of information enabled the execution of more detailed commands against specific ports to expose specific vulnerabilities. This information can then be used to address any specific vulnerabilities that are

After initial intrusion malicious software is installed on victim host that is re-ferred as RAT (remote access Trojan). RAT takes the responsibility to connect with attacker and regularly performed the actions that instructed by attacker. At this intruder take the full command and control (C2) over target host. The fact is that the initial connection is established by victim host, not by the attacker [6]. This will happens mainly for two reasons: (i) organizations firewall usually allows the connections initialized by internal hosts, and (ii) this will help the attacker to not to detected easily. Because intrusion detection systems [7] can easily detect the extremely suspicious activity such as downloads from outside hosts.

We have all herd of security breaches on corporate servers that has exposed personal and important information that should be secure. Hackers and criminals have been doing this since the invention of the internet and has only increased along with our use and dependency on networks. It is becoming more apparent that company’s need to protect their windows and Unix/Linux servers from known or unknown shortcomings and vulnerabilities from hackers who want to steal information for malicious purposes. Hackers will use codes or malware to corrupt network or operating system of the target company, with the intent to steal information such as proprietary information, personal information including social security numbers, contact information, or any

Let’s say user (A) download an execution file (EXE) on his-her PC and double click on that file, if this file is infected the virus works based on the written code by the hacker/ attacker/ intruder and copy some files into the system. In case, user (A) does not have virus protection, the virus works perfect in destroying that computer or sending information from this computer to the attacker email. Viruses not only designed to destroy PC’s, but also designed to get information from

We will first look at some known flaws in Windows 7 and Windows 8. An Information Security Engineer at Google had decided to reveal a flaw that affected two of Microsoft’s newest operating systems that allowed attackers to obtain higher privileges on an unpatched computer. The vulnerability was caused due to an error within the ‘win32k.sys’ when it processes

UPnP Internet servers were found to have remotely exploitable unchecked buffers that would allow, in principle, remote malicious hackers. Microsoft Windows is vulnerable to a buffer overflow, caused by improper bounds checking by the Universal Plug and Play (UPnP) service. By sending a specially-crafted HTTP request, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges when combined with another exploit. Unused Internet servers and services should not be left running if they are not actively needed, for this reason this port should be closed until needed.

Each of these cyber security events could have been prevented if standard security measures had been taken. Strong password management is key to protecting every organization from a breach. Weak passwords can be compromised by guessing or brute force. One of these password hacking tools is called OphCrack (Easttom, 2012). This tool understands the way Microsoft keeps passwords as a hash file on the system (Easttom, 2012). OphCrack uses this information to gain access to the local administrator account on the system (Easttom, 2012). There

We know that buffer-overflow attacks are performed by overflowing the buffer on a stack frame and overwriting the return address of the function, thereby jumping to another portion of the stack frame that contains malicious executable code that had been placed there as a result of the buffer overflow.

The first article I found gave me a better foundation for what the (Polymorphic) Worm is, where it targets and how it spreads. This particular worm spread using the internet and targeting Internet Security Systems (ISS) buffer overflows. This ISS attack using overflow is the same type of breach we practiced in one of our previous assignments this semester. The article titled "The spread of the Witty worm" discusses what it looks for and how it accesses the Internet Security Systems. Using the ISS path the Worm takes advantage of a security flaw in the firewall applications. Once breached the worm then uploads its "payload contained in a phrase, (^,^) insert witty message here (^, ^)." (Moore, 2004) This article addressed several of my concerns how what, and where? With the what? The article talks about once infected could it be removed. The report also covers where the worm goes for a suggesting a random destination within the hard drive taken over and eventually rendering the entire machine

Zero- day attacks are cyber attacks against software flaws that are unknown and have no patch or fix. Fireeye has discovered 18 zero-day attacks in the past two years, many more than the top ten security companies combined. It’s extremely difficult to detect zero-day attacks, especially with traditional cyber defense. Traditional security measures focus on malware signatures and URL reputation. However, with zero-day attacks, this information is, by definition, unknown. Cyber attackers are extraordinarily skilled, and their malware can go undetected on systems for months, and even years, giving them plenty of time to cause irreparable harm. Based on recently discovered types of zero-day attacks, it has become apparent that operating system

Two of the common known attacks on computing systems are the deployment of computer viruses and malware.

Such concerns have generally involved the infiltration of a computer system for purposes of degrading its capabilities, manipulating data, or using the device to launch cyber attacks on other systems. The Stuxnet worm, 3 which was first reported in June 2010 by a security firm in Belarus, appears to be the first malicious software (malware) designed specifically to attack a particular type of ICS: one that controls nuclear plants, whether for power or uranium enrichment. The malware attacks and disrupts a Microsoft Windows-based application that is employed by a particular ICS produced by the German company Siemens. 4 The worm can be spread through an air-gapped network by a removable device, such as a thumb drive, and possibly through computers connected to the Internet, and it is often capable of remaining hidden from detection. It is difficult to determine the geographic origin of the malware, as cyber attackers often employ

Human error: Errors caused by people who get into contact with the web application or data servers either as operators or users include; accidental deletion of data, destruction of software programs, configuration or hardware error. Vulnerabilities left by the software developers in software, is another major error. This can include authentication which can be bypassed, failure to validate input and output data, incorrect implementation of encryption, escalation of privileges, and failure to handle errors correctly can be used to attack web application leading to exposure of sensitive data such as customer’s financial data. This can be used to cause fraud to the customer’s bank or credit card.

This report mainly focuses on the computer worm known as ‘Code Red’. The crisis with this worm began with the exploitation of Buffer overflow vulnerability discovered in Microsoft IIS web server which could make the. ida ISAPI filter predisposed to buffer overflow attacks allowing attackers to gain full system level access to the web server remotely and perform any action which may include Execution of programs, manipulation of web server databases, change files and web pages leading to a full “system-level compromise”. On June 18, 2001, an advisory was released by eEye Digital Security which notified the users that a remote buffer overflow vulnerability is existing in Microsoft IIS webserver software and advised them to download a patch made available in order to address this system vulnerability.
