Israel, U.S. among top sources of cyber attacks, study finds 

SAN FRANCISCO (Reuters) - More cyber attacks originate in the United
States than in any other country, but the number of attacks that appear
to come from Israel is nearly double that of any other nation based on
number of Internet users, according to a study released Monday.

High-tech, financial services, media/entertainment and power and energy
companies showed the highest intensity of attacks per company, each
averaging more than 700 attacks per company over the six-month period.

On a percentage basis, most of the attacks were relatively benign in
nature. But the number of severe attacks was still substantial, with
critical and emergency-level events detected on 43 percent of the client
networks, the study found.

``In fact, our findings strongly suggest that once companies connect
their systems to the Internet, they are virtually guaranteed to suffer
some form of attack,'' the report said.

Average attacks per company increased by nearly 80 percent over the six
months studied.

Israel leads the list of countries in terms of number of computer
attacks per 10,000 Internet users, followed by Hong Kong, Thailand,
South Korea, France, Turkey, Malaysia, Poland, Taiwan and Denmark,
according to the study from Riptech Inc., a firm that provides security
monitoring of corporate and other computer networks.

``Israel is a country with pretty sophisticated warfare capabilities,''
that spread through the relatively computer-literate general population,
said Amit Yoran, president and chief executive of Alexandria,
Virginia-based Riptech.

For the study, Riptech investigated more than 128,000 cyber attacks
found in the analysis of 5.5 billion log entries and alerts on its
customer's networks between July and December. The company has about 300
customers in 25 countries.

While most attacks can be traced back to what is believed to be the
source country, it is possible for malicious hackers to hide their exact
location, according to Yoran.

The study found that attacks that appeared to originate in the United
States -- nearly 30 percent of the total -- were nearly triple the
second-ranked country. But only about 3.5 attacks were made per 10,000
U.S. Internet users, compared with 26 attacks per 10,000 Internet users
in Israel, the study found.

Behind the United States in percentage of total attacks was South Korea,
China, Germany, France, Canada, Taiwan, Italy, Great Britain and Japan.

MIDDLE EAST TARGETS POWER, ASIA TARGETS FINANCE

The study found that power and energy companies were primarily targeted
by the Middle East while high-tech and financial services companies were
targeted by Asian attackers.

Of particular note was the fact that the Code Red and Nimda worms were
so predominant -- accounting for about 63 percent of the malicious
activity detected by Riptech -- that they were excluded from the study.

``We had to pull them out or they would have completely skewed any type
of analysis,'' said Yoran. ``They were just so prevalent over that six
month period.''

Excluding Nimda, attacks dipped during the week following Sept. 11 but
began to rise in the third week of September, peaking in the middle of
November and declining slightly in early December, according to the
study.

Companies with more than 500 employees suffered at least 50 percent more
attacks than smaller companies, while public companies suffered about
twice as many attacks as private and non-profit companies.

Thirty-nine percent of the attacks looked targeted, appearing to be
deliberate attempts to compromise a specific system or company. ``That
was just mindboggling to me,'' Yoran said.

Yoran said the study was different from most in that it relied on actual
attack data rather than surveys of network administrators or other
company officials, which Yoran said are not always accurate.
