Symantec has said that although Internet attacks are increasing, severe attacks are down compared to last year. Security firm Symantec, which published its bi-annual Internet Threat Report on Wednesday, has found that the number of attacks over instant messaging and P2P systems quadrupled between January and June 2003.
The company uses thousands of sensors on the Internet to analyse network activity and identify global trends. According to the report, the number of viruses and worms targeting Win32 systems more than doubled, but surprisingly, severe attacks actually halved compared to the same period last year. The report criticised Microsoft’s Internet Explorer, calling it a “serious danger” because of security lapses. Several vulnerabilities allow attackers to compromise client systems through Web pages containing embedded malicious code, while others can enable easy and almost undetectable installation of spyware, which could allow attackers to extract confidential data, the report said.
According to Symantec’s figures, the average large organisation experiences almost 40 attacks every week, which is an annual increase of around 12 percent. Overall malicious activity rose by 19 percent.
