| Use Scanning Tools : Denial of Service attacks Posted: 16 Mar 2011 04:42 AM PDT There are several tools available which could detect whether a system is being used as a DDOS server. The following tools can detect TFN2K, Trinoo and Stacheldraht. Find_ddos (http://ftp.cert.org.tw/tools/Security_Scanner/find_ddos/) SARA (http://www.cromwell-intl.com/security/468-netaudit.html) DDoSPing v2.0 (http://is-it-true.org/pt/ptips19.shtml) RID (http://staff.washington.edu/dittrich/misc/ddos/) Zombie Zapper (http://razor.bindview.com/tools/zombiezapper_form.shtml) Find_DDoS...

| Posted: 16 Mar 2011 04:40 AM PDT Keep the network secure Install IDS (Intrusion Detection System) Use scanning tools Run zombie tools IDS pattern matching technologies have a database of signatures. When it finds packets that have a given pattern, it sets off an alarm. Important things to do as a current or potential victim of packet flooding Denial of Service are given below: The bandwidth used in DDoS attacks is important. Therefore, there should be proper coordination with the ISP and the ISP with the upstream ... Do you want to read more..Visit my site @ http://www.amarjit.info |
| Posted: 16 Mar 2011 04:40 AM PDT You could do the following things to minimize the DoS attack: Effective robust design Bandwidth limitations Keep systems patched Run the least amount of services Allow only necessary traffic Block IP addresses Due to the power of DoS attacks and the way they work, there is nothing that can be done to prevent a Dos attack entirely The DoS and DDoS attacks in combination with malicious codes implantations are easily launched but difficult to completely stop. With the nature of TCP/IP... Do you want to read more..Visit my site @ http://www.amarjit.info |
| Tribe Flood Network : Tools Trinoo, TFN2K & Stacheldraht Posted: 16 Mar 2011 04:40 AM PDT TFN Could be thought of as 'son of trinoo' Improved on some of the weaknesses of trinoo by adding different types of attacks that could be mounted against the victim site. Structured like trinoo with attackers, clients (masters) and daemons. Initial system compromise allows the TFN programs to be installed. Tribe Flood Network, like trinoo, uses a master program to communicate with attack agents located across multiple networks. TFN launches coordinated Denial of Service Attacks...

| Tools for running DDOS Attacks Posted: 16 Mar 2011 04:39 AM PDT Tools for running DDOS Attacks The main tools for running DDOS attacks are: Trinoo TFN Stacheldraht Shaft TFN2K mstream Trinoo UDP packet flood attack No source address forgery Some bugs, but full control features TFN Some bugs, limited control features UDP packet flood attack ("trinoo emulation") TCP SYN flood attack ICMP Echo flood attack Smurf attack Either randomizes all 32 bits of IP source address, or just the last 8 bits TFN2K Same attacks as TFN, but can randomly...

| Denial of Service attacks : Hacking Tool Posted: 16 Mar 2011 04:39 AM PDT Hacking Tool: SSPing SSPing is a DoS tool. SSPing program sends the victim's computer a series of highly fragmented, oversized ICMP data packets. The computer receiving the data packets lock when it tries to put the fragments together. The result is a memory overflow which in turn causes the machine to stop responding. Affects Win 95/NT and Mac OS SSPING is a program that can freeze any computer connected to the Internet or on a network running Windows 95, Windows NT, and older ...

| Posted: 16 Mar 2011 04:39 AM PDT Ping of Death An attacker sends a large ping packet to the victim's machine. Most OS do not know what to do with a packet that is larger than the maximum size, it causes the OS to hang or crash. Example: Ping of Death causes blue screen of death in Windows NT. Ping of Death uses ICMP to cause a denial of service attack against a given system. Ping of death is a denial of service (DoS) attack caused by an attacker purposely sending an IP packet larger than the 65,536 bytes allowed by...

| What is Distributed Denial of Service Attacks Posted: 16 Mar 2011 04:39 AM PDT What is Distributed Denial of Service Attacks An attacker launches the attack using several machines. In this case, an attacker breaks into several machines, or coordinates with several zombies to launch an attack against a target or network at the same time. This makes it difficult to detect because attacks originate from several IP addresses. If a single IP address is attacking a company, it can block that address at its firewall. If itDDoS attacks involve breaking into hundreds or... Do you want to read more..Visit my site @ http://www.amarjit.info |
| Types of Denial-of-Service Attacks Posted: 16 Mar 2011 04:39 AM PDT Types of Denial-of-Service Attacks There are several general categories of DoS attacks. Some groups divide attacks into three classes: bandwidth attacks, protocol attacks, and logic attacks. Bandwidth/Throughput Attacks Bandwidth attacks are relatively straightforward attempts to consume resources, such as network bandwidth or equipment throughput. High-data-volume attacks can consume all available bandwidth between an ISP and your site. The link fills up, and legitimate traffic...

| Next Topic: Denial of Service attacks Posted: 16 Mar 2011 04:39 AM PDT Friends, tomorrow onwards, we will look at various aspects of Denial of Service attacks. The discussion will include topics such as: What is a Denial of Service Attack? What is a Distributed Denial of Service Attack? Why are they difficult to protect against?

| Learn How to Establish a NULL Session Posted: 15 Mar 2011 11:47 PM PDT The NULL session is used on Windows computers via the Inter-Communication Process (IPC$) to allow the viewing of shared resources. This connection is made without a username or password.An attacker will use the NULL session to enumerate user information from the target.From command prompt enter the following syntax: net use \\Target IP Address\IPC$ ""/u:""When successful, the result will show The command completed successfully and this is not logged in the System Event Log.---Regards, Amarjit...
