Several Israeli Web Sites Down
July 14, 2006

Fighting along Israel's border has led to hacker attacks against hundreds of
sites.

The fighting along Israel's northern border with Lebanon has brought with it
an upsurge in attacks on Israeli-related web sites in the past 24 hours,
Israeli web sites reported Thursday.

As the violence escalated, hackers from the Islamic world have targeted web
sites hosted by all of Israel's major Internet service providers.

To counter the threat, the ISPs added even more security to protect their
servers from the latest round of digital warfare. Most of the attacks are
coming from hackers located in Morocco and Turkey.

"We witnessed hundreds of application layer attacks against Israeli-related
web sites," said Ariel Pisetsky, manager of engineering and security at
NetVision, one of Israel's leading ISPs. He added that this kind of attack
has become increasingly prevalent in recent years.

Local ISPs are deploying more aggressive security to deal with the threat.
The latest onslaught came within hours of Wednesday morning's outbreak of
hostilities. The hackers look for vulnerabilities on Israeli web sites and
domains.

They search for domains ending with the suffix co.il. Typically the hacker
searches for file-uploading or scripting capabilities. Once the
vulnerability of these capabilities is located, files are uploaded to deface
the site.

 
Rapid Response

NetVision and other ISPs responded within a matter of minutes. "Our
immediate response was to make it far more difficult for all users to enter
the web sites," noted Mr. Pisetsky.

In NetVision's case, the company immediately deployed two new security
technologies that it began testing in recent weeks on a trial basis on the
servers that had come under attack.

Israeli ISPs are tightlipped about the latest security software systems they
are deploying to counter the sharp rise in application layer attacks, but
many are being developed by local startup companies.

 "This field of security is very hot and a number of local startups are
focusing their attention on this space," said Dan Yachin, a Tel Aviv-based
research director for emerging technologies at IDC.
