There isn’t a profitable business segment today that isn’t competitive and that even includes the SPAMMING industry. Two of the biggest Spamming organizations, Nugache and Storm are currently going at each other head to head to dominate the SPAM/malware market. Yes, there is a market for SPAM and malware. Surprised? These organizations are not owned and operated by legitimate business people. No in is yet sure who is behind Storm but many IT security experts feel that Nugache is linked to the Russian Mob, aka the Russian Business Network.
Both of these organizations distribute SPAM through Zombie networks and both have been involved in highly criminal activities. Zombie networks are composed of PC’s across the globe, which have been compromised by some type of Trojan Horse which allows the Zombie controllers to then use them to send SPAM, conduct phishing attacks or other types of illegal activities. Each of these organizations control hundreds of thousands of computers. Take Storm for example. Some IT security experts have estimated that the Storm Zombie network, called the Storm Botnet, runs anywhere from one to fifty million computer systems. Even the most conservative estimates place the size somewhere around 150,000 to one million. The Storm Botnet in 2007 accounted for 8% of all malware on Microsoft Windows computers.
This year, Storm has an extremely viable competitor, Nugache. Although its zombie technology is not as sophisticated as Storm’s (for instance, Storm is somehow able to send SPAM in the native language of the receiver while Nugache cannot) Nugache has a big thing going for it right now, price. In an attempt to unseat Storm from its botnet dominance, Nugache has initiated a price war. Nugache will send one million emails for only $100. For $800 you can send 10 million emails.
It is because of the ridiculously meager amount of money that is required to SPAM a million people that SPAMMING is very profitable, even if the response rate to SPAM is only .01%. It is the sophistication of these controllable zombie networks that worry IT security professionals. Many fear that the current war for control of the malware market is only the beginning of this illegal destructive industry.
Johnny Lee is a brilliant technologist who’s become a YouTube star through his amazing demonstration of Wii remote hacks. After watching this video, you’ll never look at your Wii the same again. I love this video because Lee once again proves how integral human creativity and ingenuity are to the process of technological innovation. In this case, a relatively unknown guy like Lee on center stage at the famed TED conference, reinventing the very essence of what an already popular technology’s applications can ultimately be. These hacks are insane. Don’t miss this one…
The 2008 Global Information Security Workforce Study was recently released. A total of 7,548 professionals in the field were surveyed. The complete study can be downloaded at https://www.isc2.org/cgi-bin/content.cgi?category=510
The most interesting headline from the study was the fact that 70 percent of all respondents reported that their own employees are the biggest threat to their organization’s security. This is contrary to the common belief that organizations must throw most of their resources at the outside perimeter of the organization’s network to prevent outsiders from accessing their network.
This premise is supported by a recent finding that email is now no longer the number one manner in which viruses access an organization’s network. With the ease at which employers now bring in thumb drives, personal laptops and PDA’s. Network security plans must focus on an umbrella approach that guards the entire network.

Back in 2000, we were constantly told that the world was running out of IP addresses. This was because IPV4, the IP standard we use for IP addresses only has so many mathematical combinations, thus there is a defined limit to the number of IP addresses that can be utilized. Due to the wide spread use of IP in the world, a usage rate far beyond what the creators of IP ever visualized; the IT world was stressing out as to how to address the problem. The solution was a new standard called IPV6 which introduced more bits into the addressing scheme. In turn, millions of additional mathematical combinations were created, resulting in an equal number of additional IP addresses.
Unfortunately, IPV6 is more complicated than its predecessor, requiring a degree of training for networking professionals. We were told back then that IPV6 would be implemented by the middle of the decade and alleviate the crisis.
Well guess what? It’s 2008 and the world hasn’t run out of IP addresses which is why IPV6 is barely used in the industry today. This is because of the wide popularity of NAT, Network Address Translation, which is used by most organizations that have a WAN presence.
For those unfamiliar with NAT, Network Address Translation allows a single device, such as a router to act as an agent between the Internet (or “public network”) and a local (or “private”) network. This means that only a single, unique IP address is required to represent an entire group of computers. This isn’t to say that IPV6 will wither on the vine. As of right now, government offices are required to transition to IPV6 within the next couple of years and other organizations are planning such an implementation in the future, but IPV4 is and will continue to be alive and well for some time to come.
One of the security weaknesses experienced with laptops and other portable computer devices for many years is the simplicity in which their drives could be compromised if the device is stolen. This was especially true before Windows XP and Windows 2000 when a thief could simply install a second operating system on the laptop, logon to the new operating system and gain admin rights to all the data on the drive.
Windows XP and Windows 2000 introduced EFS, Encryption File System, which allowed users to encrypt files of their choosing. Because the encryption was centered on an encryption key based upon the original operating system, an intruder couldn’t access that file simply by accessing it through another operating system. However, this required the user to individually encrypt every file or folder in order to protect all of their data. Needless to say, the majority of users failed to do this.
Microsoft has introduced a new technology called BitLocker with Windows2008 and premium flavors of Windows Vista. BitLocker encrypts the entire drive, including the Windows system files necessary for startup and logon, which could give an intruder the ability to discover passwords and logon information. What’s more, BitLocker utilizes a feature called Integrity checking which analyzes the early boot components and helps to ensure that data decryption is performed only if those components appear unmolested and that the encrypted drive is located in the original computer. This prevents thieves from stealing your hard drive and putting it into another computer to access the data.
It will also make it much easier for organizations to recycle old computers as they will not have to worry about erasing data on machines being decommissioned as the drives will be inaccessible. BitLocker is a great new addition to the Windows operating system and should be implemented by any organization or individual that works with sensitive data.
It’s standard practice that if you have an always-on Internet connection, then you should have a firewall, implemented in either hardware, such as a router, or in software. But even if you are using a dial-up connection, you really need a software firewall to protect you from intrusions. You would be surprised at the number of attempts to get into your PC a good software firewall will block on a PC using dial-up. A firewall will also notify you of attempts to go out to an Internet website. You can then allow or disallow the outbound traffic. You would want legitimate programs such as Windows to access the company’s website for update purposes, but you’re safer to block any programs that you don’t recognize from doing so. Be sure to check for correct spelling. Say you have Symantec’s anti virus program on your PC and have set it up for automatic virus signature updates. Your firewall will ask you whether you want to grant the program permission to go outbound. But some malware could identify itself as Symantek. Should you allow it to access the Internet, you could be in for an unpleasant surprise.
Yes, it’s unfortunate that there are so many nasty things that can happen to your computer. And thwarting such attempts can cost you time and money, but you really need to do this. At minimum you need a firewall, an anti-virus program, and an anti-spyware utility. You’ll also need to update the anti-virus and anti-spyware programs’ signature files at least once a week, as well as scanning with each at least once a week, more frequently if you are online daily.then you should have a firewall, implemented in either hardware, such as a router, or in software.

The threat of “cyber-terrorism” still strikes many as abstract, a symbolic fear first represented in seminal works such as William Gibson’s Neuromancer, followed by an explosion into pop-culture fantasy through the Wachowski Brothers’, “The Matrix.” While these dark visions of man’s accelerated move towards techno-slavery have certainly colored our perspectives, the reality of cyber-terrorism has existed since the 1950’s, when state secrets were first buried in dense programming language instead of manila folders labeled “top secret.”
Behind the curtain, the borderless battlefield is virtual and the threats are as imposing as those posed by nuclear weapons. After all, launch codes are just that—codes that are developed, stored, distributed, and controlled within cyberspace. The following podcast interview features Bruce Hoffman, a cyber-terrorism expert who outlines the precise nature and ominous implications posed by this threat. Mr. Hoffman also presents us with an in-depth report on how the U.S. government has redirected its’ counterterrorism strategies. Do you see a future where the Internet is under government control? Let’s think inside the box and brainstorm on the possibilities. Thanks.

The architecture of cyberspace is interconnected, timeless, and invisible from the inside-out. On the Ashworth University Blog, we’re not afraid of the matrix and try to share perspectives from around the world, just a 0 1 code, on the technology issues that influence how this network will evolve in complexity, and most of us would like that evolution to be open rather than closed in principle. Earlier this year, the nation of Estonia was involved in what by any measure must be considered one of the most large scale and sophisticated “cyber attacks” in history, an attack that operated on several levels simultaneously, resulting in the virtual collapse of this nation’s electronic infrastructure. Instantly, the fundamental question, “who did this?” was buzzing with elements of fear and conspiracy. Did Vladimir Putin and Russia conduct this operation in the shadow of political revenge? Was the attack the work of loosely connected and politically marginalized hackers who were sending their own message to an establishment attempting to exert increased state control over the Internet, i.e. you’re more vulnerable than you think and we’re waiting for your next move. The following video consists of an interview with information security expert, Dmitry Skylyarov, in which he shares his inside perspective on what occurred and the big picture implications of what is perhaps the most misunderstood yet powerful of political weapons; the large scale, well conceived, organized, and executed cyberattack. This is a must watch interview. Click on the image above to watch this video. We look forward to hearing your thoughts.
If you are in the IT Field or considering getting into it, you don’t need rose colored glasses to see a promising future for yourself. The Bureau of Labor Statistics recently reported that IT will be the fastest growing sector of our economy for the next ten years. They also report that the three fastest growing jobs in the US are network system and data communication analysts, computer systems analysts and software application engineers. In fact, in just about any top ten list, you will find IT has the most positions of any field.Now couple this tremendous growth with the following statistic:
The labor force for the 25 to 54 age group in IT will only grow at a dismal .2% between 2006 and 2016.
Do you want to be in demand for the next decade? Stay committed to your program studies and your hard work will pay off. The bottom line is that it’s important to obtain as many skill sets as you can in the rapidly expanding IT industry. If you need assistance with your lessons, I encourage you to reach out to me in the comments section of this blog. I always look forward to hearing from my students!
In reference to my introduction to VMware, one of the most exciting networking software applications to come to fruition in some time, I wanted to offer a little background what a SAN (storage area network) is. First off, VMware’s parent company, EMC is the #1 manufacturer of SANs in the world. A SAN is also required in order to make the most of VMware. SANs have also been transforming the data storage market over the past several years.
There are three types of storage today:
Direct Attached Storage - a tape unit attached to a server
Network Attached Storage - a dedicated storage server that resides on the internal network
Storage Area Network – A collection of storage devices that reside on a separate private LAN
Direct Attached Storage is still used today in small organizations with only a few servers although some organizations may still use this outdated method in larger organizations. It consists of have a separate tape storage device directly attached to each server. The backup process is managed by some type of backup application which automatically backs up the server at a specified time each night. However, it does require someone to change the tapes every day. The personnel cost and management of this model doesn’t make it viable for a large network structure. Also, the replacement costs of multiple tape drive units are cost inhibitive as well.
Network Attached Storage consists of a server placed on the network built of numerous very large hard drives. In most instances, all backup processes of network servers are managed by a backup application such as Veritas from a designated server. The application then directs all involved servers to backup their files to the NAS server. This is a very simple and relatively inexpensive model to implement. The problem with the NAS model is that the NAS resides on the Ethernet network. This means that the backup traffic competes with the other traffic on the network for bandwidth. Although organizations almost always run their backups at night, for many organizations with terabytes of data, backups must run during active network hours as well. This will slow down the network and impact its efficiency.
