Dangerous Worm on Windows

January 22, 2009

Downadup/Conficker worm

We saw a large amount of infections from the Downadup worm last month. This worm is also known as Conficker or Kido and is able to spread very quickly because it uses 3 effective ways to propogate:

  • Exploits a Windows vulnerability MS08-067. The patch was released a long time ago but there are still a lot of unpatched computers.
  • Exploiting network shares with weak or no passwords. The worm contains a list of common passwords - a good reason to use strong passwords.
  • Copies itself to removable media, usually USB sticks. Using the AutoRun function (creates autorun.inf file)

The first versions of Downadup were seen at the start of December 08 and until now we have observed more than 300 different variants. All known variants are detected and healed by AVG. Besides spreading, the worm can also download other malware and can redirect legitimate URLs access to various other malicious webpages.

We strongly recommend that you install all of the latest security patches for your version of Windows.

" Cut Costs Now
With decreasing budgets and increasing demands, IT professionals are under constant pressure to do more with less. And as an open source operating system, Linux is an attractive enterprise choice for several reasons-portability across a variety of commodity hardware architectures, an active community of contributors, and zero license cost."

US Security Experts Fear 'Cybergeddon'

US Security Experts Fear 'Cybergeddon'
Agence France Presse (01/07/09)

Shawn Henry, cyber division assistant director at the U.S. Federal Bureau of Investigation (FBI), says that beyond weapons of mass destruction, cyberattacks pose the greatest threat to the United States. U.S. experts warn of a "cybergeddon" in which an advanced society that has most of its major infrastructure systems linked to or completely controlled by computers is sabotaged by hackers. Henry says terrorist groups are working to create a virtual 9/11 that would inflict the same kind of damage to the U.S. as the 9/11 attacks did. Last year, Russian hackers allegedly launched a major offensive against Internet networks in Estonia and Georgia, and Palestinian sympathizers have coordinated attacks against hundreds of Israeli Web sites over the past few days. "We're seeing that the folks on the cutting edge of this tend to be the bad guys," says the FBI's Donald Codling. "It's extraordinarily difficult for us to catch them." The FBI's Christopher Painter says cyberattacks are particularly dangerous because the threat is largely invisible and not always taken seriously as a result. "It's hard to get your head around the threat," Painter says. "We often discover a company has been attacked and we tell them that and they don't know."

Information Technology and Gaza Operation

Media Matters: Cloudy skies over Gaza :Jpost

Chanasys: Technology not the Same in Gaza Conflict compared to 2006 Lebanon 2

From the Jerusalem Post

Jan. 8, 2009 Media Matters: Cloudy skies over Gaza
Ruthie Blum Leibowitz , THE JERUSALEM POST

As missiles from Gaza continue to bombard the South, the entire country is being blitzed by another airborne force: the news. This is as natural as it is necessary.

Operation Cast Lead is the story - the only one, other than the weather report, that anyone is really interested in right now. Proof of this lies in Channel 10's decision to take the hit, Survivor - the second season of which began with a bang, so to speak - off the air "until further notice."

This future date could be, say, when there's a cease-fire, or another reason for reality shows to resume receiving higher ratings than reality itself. You know, the point at which the parents of combat soldiers, whose cellphones are confiscated before they enter the battle zone, no longer need to rely on reports from the field to feel connected to their sons. That this connection is a bit of an illusion, since crews have been reporting from the home front, not from inside Gaza, makes little difference. As one worried father put it this week, "I'm like a junkie who can't tear myself away from the TV, even though it tells me nothing of my boy's actual whereabouts or condition."

He is not alone in his addiction. And the media are dutifully supplying the national drug.

So much for why the news barrage is natural. Why it is necessary goes even deeper.

The media have become a chief branch of society, government and even of the IDF, whichever way you slice the pie chart.

This is not to say that the press is controlled by any of the above. On the contrary, if anyone has been calling the shots in recent years it's been the "watchdogs of democracy." Well, they and their rival for influence on politicians - the polls.

There is no getting around the fact that the media have become central players in all dramas-of-state, whether that state is democratic (in which case the production is improvised) or totalitarian (in which case it is staged).

Nor can anyone deny that modern technology is as responsible for the phenomenon as it is manipulated by it. When amateurs and professionals alike have access to digital equipment and the Web, photos, footage and ongoing commentary fly around cyberspace as freely as Kassams, Grads and Katyushas do over Sderot, Ashkelon, Ashdod, Beersheba and Nahariya, to name but a few of the locales within Hamas and Hizbullah rocket range.

As a result, a country like Israel, which has been under physical and ideological assault since its establishment, is in a constant quantitative and qualitative information predicament. And never is this predicament more apparent than when the country is engaged in an actual war.

Quantitatively, Israel is at an information-dissemination disadvantage by virtue of its small size and that of the sum of its supporters worldwide. This is not new, nor is it the main problem. Public diplomacy on the part of people unwilling to lie in order to convey a message simply has to be heavier on the brains than on the brawn. It's a challenge, to be sure, but one that is as accepted as it is assumed.

It's the qualitative predicament that presents the larger quandary. As a democracy with a free press - and a foreign one greeted with a welcome mat and red-carpet treatment - Israel is like an open book. This means that it has many editors and even more critics.

We wouldn't have it any other way. But neither would those who don't have its best interests at heart.

HERE IS where the army enters an arena that we in the media normally would view as our sacred space, never to be invaded. Under any other circumstances, the curtailing of our freedom of expression would be construed as a ground invasion into our sovereign territory.

Indeed, even under the current circumstances, correspondents and editors often are chagrined when the Military Censor's Office exercises its might. At best, we feel inconvenienced by being coerced into submitting our work to a body viewed by many of us as anachronistic in the age of the Internet. It seems silly to remove certain details from an article or a broadcast, when the very same ones are being revealed elsewhere for all to see. Even more ridiculous: An item that is given the heads-up one day by the censor's office might be nixed the next, depending on the staff member whose shift it is.

Still, we also recognize and respect its task: to prevent the leakage of information that could endanger individuals, jeopardize national security or - no less important - cause emotional pain to families of fallen soldiers or civilians. It is for this reason that, in spite of our bitching and moaning, we uphold the written law as we would an unspoken code of honor.

This wasn't always our behavior. During the Second Lebanon War, clashes between journalists and the censor erupted over coverage of troop movements and casualties. There was a lack of coordination and rumors ran wild. There were even cases of parents learning that their sons had been wounded or even killed through TV channels, rather than military ones.

Among other lessons supposedly learned from the failures of that war was the importance of caution and restraint where exposing details of military operations is concerned. This is why extra care is being taken by reporters not to reveal the exact location of missile hits, for example - a rule the censor insists is golden, as is keeping quiet about which missiles turned out to be duds, which fell into the sea and which struck strategic targets or IDF bases. According to guidelines released by the censor's office at the start of Operation Cast Lead at the end of December, the purpose of the above is to prevent the "other side" from being able to adjust its rocket launchings, based on details of their landings.

KEEPING A haze over the precise goings-on of the operation may be responsible journalistic practice, but it creates a different kind of difficulty for members of the press, particularly those on screen. Which brings us back to the original point.

Filling up hours upon hours of airtime with the news everyone so craves these days is no easy feat when much of that news is censored. This has led to the phenomenon of there being more punditry provided than actual reportage. One can't help but feel sorry for the likes of Channel 1's Yoav Limor and Yinon Magal - for instance - standing in the cold, on camera, with a vague, dark Gaza skyline in the background, trying to blah-blah their way intelligently through entire broadcasts.

Then there are the endless interviews in the studio with ex-generals and Post Traumatic Stress Syndrome experts, Mideast analysts - and regular appearances by the Home Front Command's Col. Gil Shenhar, reiterating procedures for the public follow prior to, during and after an attack.

This should only be our worst problem in the upcoming days.

Amazon says 2008 holiday season was 'best ever'

SEATTLE - Online retailer Amazon.com Inc. called this holiday season its "best ever," saying Friday that it saw a 17 percent increase in orders on its busiest day — a rare piece of good news in a season that has been far from merry for most retailers, including online businesses.

Amazon customers ordered more than 6.3 million items on Dec. 15, compared with roughly 5.4 million on its peak day last year, the company said. It shipped more than 5.6 million products on its best day, a 44 percent rise over 2007, when it shipped about 3.9 million on its busiest day.

The company did not provide dollar figures and wouldn't say whether the average value of orders had changed, and the jumps it reported Friday are in line with increases Amazon has seen since it started releasing the figures in 2002.

Amazon's best-sellers included the Nintendo Wii game console, Samsung's 52-inch LCD HDTV and Apple Inc.'s iPod touch.

Analysts agreed Amazon's report was good news for the online shopping giant, but they were divided over whether the results indicate strength in online commerce in general.

Forrester Research analyst Sucharita Mulpuru said Amazon's experience shows the current economy is favoring discount retailers, both online and offline.

"The Amazon story doesn't surprise me because Amazon has always traditionally been a leader on price, and they're one of the first places consumers go when they're looking for things online," Mulpuru said. "In many ways they're like the Wal-Mart of the online world."

Wal-Mart is one of very few traditional retailers where revenue has risen this holiday season over last.

Holiday sales typically account for 30 percent to 50 percent of a retailer's annual total, but rising unemployment, home foreclosures, the stock market decline and other economic worries led many shoppers to slash their shopping budgets this year.

SpendingPulse — a division of MasterCard Advisors — said its preliminary data show that online sales fell 2.3 percent compared with the 2007 holiday season, while retail sales overall fell 5.5 percent to 8 percent, including sales of cars and gasoline. The decline was 2 percent to 4 percent when auto and gas sales are excluded.

Online shopping may have gotten a boost from winter storms during last two weeks before Christmas, which made travel to brick-and-mortar stores more difficult.

And, although Amazon's orders rose, the company didn't say whether orders were, on average, worth more or less than last year. Spokeswoman Sally Fouts said the company would release revenue results in its fourth-quarter earnings report, due in about a month.

But she said this was Amazon's "best season ever."

Orders to Amazon on the peak day of its holiday season have jumped in the double-digit percentage range for at least the past 5 years, according to data released by the Seattle, Wash.-based company since 2002. Last year, Amazon's orders spiked 35 percent to 5.4 million at their peak, from 4 million in 2006.

Stifel Nicolaus & Co. analyst Scott Devitt said online retailers' sales tend to grow much faster than those of brick-and-mortar retailers, but he said that difference narrowed this year. That's in part because shoppers tend to go to stores for necessities and online for discretionary purchases, he said. And in an economic downturn, consumers focus on their most-needed purchases and cut back on more frivolous items.

Devitt said Amazon benefited from a vast infrastructure that allows for faster, more reliable shipping than most of its online peers offer. He called Amazon's announcement an "extremely positive data point" and said the company is "uniquely positioned to do well in an environment like this."

That environment has left many retailers in a tough position. NPD Group senior retail analyst Marshal Cohen said they will be forced in coming weeks to take still more drastic measures to drive sales and raise whatever cash flow they can.

Amazon's shares gained 34 cents to close Friday at $51.78, a 0.7 percent rise.

Haaretz: YouTube allows Web users to interview Israel's future prime minister

YouTube allows Web users to interview Israel's future prime minister

By Oded Yaron, Haaretz Correspondent

The 2009 elections appear to be the first in which the political system has been invaded by the internet and its tools. With more and more resources being invested in Israel in online campaigning, and with politicians' blogs and videos being virally disseminated via email, the influence of the recent U.S. election is apparent.

Now, a Channel 2 news initiative, in cooperation with the popular video sharing website YouTube, is riding the America-style elections trend with a new interactive Web page devoted to the upcoming general elections.

The page, (http://www.youtube.com/Elections09), invites internet users to upload 25-second videos addressing Israel's political candidates with questions. The page's viewers will be able to vote on the uploaded videos, and the most popular entries will be aired on Channel 2 and answered live by the candidates themselves.

In addition, the project promises that the winning entrants will be invited to the Channel 2 news studio to take part in a live interview with the prime ministerial candidates.

    Wikipedia goes to Ubuntu/Computerworld

    Wikipedia simplifies IT infrastructure by moving to one Linux vendor

    It's moving 400 servers to Ubuntu Linux from a mix of Red Hat and Fedora

    Todd R. Weiss

    October 9, 2008 (Computerworld) Since the free, online Wikipedia user-created encyclopedia began in 2001, the Linux-based IT infrastructure behind it has been expanded and lassoed together to keep up with the demands of the popular Web site.

    That meant that often it was haphazardly expanded by tossing in a new server with a different operating system each time. Over five years, the servers were running a variety of versions of Red Hat Linux and Red Hat Fedora, making it more complicated to install applications and maintain the servers.

    Soon, that problem will be gone.

    In a few months, Wikipedia will finish a major transformation by moving from a combination of versions of Red Hat products to Ubuntu Linux Version 8.04 on all 400 of its servers that support the Web site.

    The changeover began in 2006 as the growth of the site took off, said Brion Vibber, CTO of the San Francisco-based Wikimedia Foundation Inc., the nonprofit group that supports the online Wikipedia encyclopedia and other projects.

    We had a mix of things: some Red Hat 9, some Fedora – several different versions,” Vibber said. The group used a custom-scripted installation procedure, but found that having a multitude of versions was more difficult to maintain for its small five-person IT staff around the world.

    The move to all-Ubuntu was primarily done with the goal of “making our own administration and maintenance simpler,” he said. “We decided that we want to standardize on something.”

    The switch has been done over time, starting with caching proxy servers in 2006 and moving on to other servers in segments. Today, the group is continuing to transition its main application Web servers to Ubuntu as part of its regular maintenance schedule, Vibber said.

    Most of the group’s 400 servers are in a data center in Tampa, Fla., while a few reside in secondary data centers in South Korea and Amsterdam.

    It definitely has gotten a lot simpler,” Vibber said. Mass upgrades can be done more easily, and the data center can be managed as a unit, he said.

    We can run the same combination everywhere, and it does the same thing” and runs the same software, Vibber said. “Everything is a million times easier.”

    Steven J. Vaughan-Nichols: Ubuntu scores major Wikipedia win

    The mixture of Red Hat operating systems was created as Wikipedia quickly grew, backed by a group of volunteer IT people who created it out of what they had available. In 18 months, the original site went from around 15 servers to 200, making maintenance and operations a whole different ballgame, Vibber said.

    Gordon Haff, an analyst at Illuminata Inc. in Nashua, N.H., said Wikimedia’s switch from Red Hat to Ubuntu is also likely a result of Ubuntu’s making the enterprise server and consumer desktop versions of its operating systems available for free to all users, with no lightening of the systems for nonpaying customers.

    Red Hat used to do that years ago, but then moved to a model where its free and paid versions differed in some features and abilities, he said. Now the Fedora community Linux project is separate from the flagship enterprise version of the operating system, adding to the factors that must be considered by users, he said.

    The problem with having multiple paid, unpaid and community versions is that a customer then has a menagerie of products that may or may not be as easily compatible, Haff said.

    Wikipedia could just as easily have made the switchover to all Red Hat, but that would have cost more money, he said. “It would seem to me that if money weren’t an issue here, there wouldn’t be anything keeping them from upgrading everything to Red Hat.”

    The collaborative Wikipedia encyclopedia is written by volunteers around the globe. The project includes 75,000 active contributors working on more than 10 million articles in 250 languages, including more than 2.5 million articles in English, according to the group. The site has about 684 million visitors a year. The Ubuntu changes affect all Wikimedia Web sites

    Happy New Year with Israeli Hitech as Reported on BBC

    Collaboration ( from an article on bbc today about Israeli Hightech)

    You can find further evidence of fruitful collaboration on the outskirts of Jerusalem, home to a joint Israeli-Palestinian company, G.ho.st.

    The brainchild of serial entrepreneur, Zvi Schreiber, G.ho.st stands for Global Hosted Operating System, a free web-based virtual computer which, as the company puts it, offer users a personal desktop, files and applications "available from any browser, anywhere".

    Uniquely the company operates across the physical and psychological barriers that divide the country, with 40 employees based in Ramallah, and six in Jerusalem. This is not about outsourcing - the employees on both sides are shareholders in the company and are paid competitive salaries.

    Despite the logistical challenges - the only full company meeting so far took place in a petrol station restaurant on the Dead Sea - Ori Weinroth from G.ho.st's Jerusalem office believes the business model "seems to be working smashingly".

    And some believe this is exactly the kind of creative innovation that could make a contribution towards helping to resolve the conflict between Israelis and Palestinians.

    With economists identifying key challenges including the soaring cost of occupation and a growing "brain drain", companies like G.h.ost that can bring the two communities together are being watched closely by leaders the world over.
