Emerging Corporate Information Security Threats
The time when worms and viruses were a top priority streamyx down 2008 IT are long behind us. Botnets and phishing attacks now webmail tm net my the webscape and new variations are emerging daily.
Botnets:
To give you an idea on how prevalent this threat is becoming, Zombie Master Jeanson Ancheta pleaded guilty to seizing control of hundreds of thousands of Internet-connected computers and renting the zombie network to people who used it to send out spam. Keep in mind that this "Zombie Network" included computers at the Weapons Division of the U.S. Naval Air Warfare Center in phone and broadband packages Lake, California, and at the U.S. Department of Defense.
Ancheta admitted that the scam streamyx rm45 him over $60,000 over 14 months before it was detected. This mindset, motivated by money and working in the background, is typical of the new generation of Internet criminals. The spyware they surreptitiously plant on an unsuspecting user's computer leaves a very small footprint (barely detectable) and worka as a "Slave" to a remote "Master". The End user usually isn't aware that their personal computer or workstation has been "hijacked" as the computer continues to function, perhaps a little slower.
"Botnets", also known as Bot Networks, are masses of hijacked computers, sometimes numbering in the hundreds of thousands as was the case with Ancheta who admitted to directing more than 400,000 computers. Industry research indicates that almost 200,000 computers become zombies EVERYDAY and that figure is steadily rising (Source: CipherTrust).
Historically, Botnets were used to launch DDoS (Distributed Denial of Service attacks) on websites. A disturbing new trend developed by this generation of Internet criminals is to rent their networks to those who want to launch cheap mass email campaigns (also known as Spam) or to broadband speed meter to launch DDoS attacks on legitimate websites. Botnets pose an even more insidious threat. According to Dave Rand, Chief internet phone service at Trend Micro, their combined computing power could be used to decrypt Internet traffic. If that were to happen (and thankfully there is no sign of it yet), it could bring e-commerce to a grinding halt.
Phishing Expeditions:
Industry experts kuala lumpar that phishing attacks will grow in frequency and sophistication over time. This trend is streamyx in malaysia developing at a fast pace as pointed by David Sancho, an antivirus engineer at security company Trend Micro. David pointed out an attack in Germany which claimed to be from a power company and asked the recipients to click on an attached file that appeared to be a PDF document, which is a file type that the power company uses for paperless billing. In actuality, the file had a .pdf.exe extension and installed a Trojan on the user's computer when it was executed.
The Trojan then monitored the user's Internet activity (Web pages and online banking access), and sent this information to the Trojan's creator. "It is smarter, because they (the Internet criminals) don't have to set up a fake server,", said David.
According to Mikko Hypponen, Chief Research Officer at F-Secure. "The bad boys are getting more professional and doing more targeted attacks."
Though Windows PCs remain the primary target for attacks, prepare to see more sophisticated Botnets and phishing attacks, as well as attacks targeting cell phones and RSS News Feeds.
The Solution
These attacks are major problems that cannot be easily resolved, because the target PCs are primarily home computers and corporate networks connected to an ADSL line. According to Hypponen "It takes a lot of end-user support to explain to a grandmother how to configure the computer. So most ISPs are not doing anything about it".
For networked environments, there are several alternatives that can be implemented at your network's perimeter to mitigate the security risk. If you believe your personal computer or organization's network may be at risk, please consult a PC expert or corporate information security consulting firm for immediate assistance.

As William Gibson said, "The future is already here - it is just unevenly distributed." A few years ago dsl provider thought streaming video was an impossible dream. Networks were too slow, comcast speed test said, and no one cared about streaming. A few us held the torch high and shouted in a stentorian voice "We shall broadband provider but it was still not to be. We had TiVo, but that was securely ensconced on a hard drive in a box that sat next to my TV. I could get some video online - there were brief glimmers of hope with sites like streamyx pop3 setting and their ilk (basically, web-based piracy sites) and Google Video which promised full-length films online. But I always stuck by Netflix and DVDs. I recall now that when my son was born, three years ago, we were on the 3 DVD/ unlimited choice plan on Netflix. Now, with my new daughter mewling by the TV, I'm on the 1 DVD/streaming plan. Things are changing drastically.I have 83 movies on my Roku box. I have video-on-demand - from Netflix - on my Xboxen and on my desktops. I have easy access to movie rentals and purchases on multiple devices in my gadget constellation and, if I so desired, I could have downloaded - with dubious legality - the entire Oscar contender list in about four hours for playback on my hacked Apple TV. Hulu and other sites offer TV downloads. All this leads to a few important points. Please allow me to ruminate.My goodness! 99pc of rumours are true?
DEC 15 ?Gosh! I nearly fell out of my chair when I saw the interview of RPK ?you know, the masters graduate in ISA studies from Universiti Kamunting (UK) ?in the Riz Khan programme (Astro Channel 513).
When asked about his website Malaysia-Today, this is what he said: "Ninety-nine per cent of the rumours eventually turn out to be true." Error is only one per cent. So sue him! He also said: "I have always been told tmnet streamyx setting two things sell, and that is tm net clickers and politics. And sex involving politics sells even more."
Now I don't know about you, but if 99 per cent of rumours in this country become reality later, boy, are we in trouble. Lets look at some of the juiciest rumours making the rounds now:

Based on what Ive read about other WordCamps and now having attended one, I think I can safely say that each one is a different experience.I have to confess it wasnt entirely what I was expecting, but thats not entirely a bad thing?
