60/100 mest populära sajter infekterade under 2008

[brainslicer]

Ett som annat drabbar både sajter och besökare i dessa dagar, så kan väl vara på sin plats att fundera över säkerhet, beteende o sånt ibland..

 

Några mer eller mindre intressanta punkter utplockade från:

 

Websense Security Labs™ State of Internet Security Q1 – Q2, 2008

http://www.websense.com/securitylabs/docs/WSL_Report_1H08_FINAL.pdf

• 75 percent of Web sites with malicious code are legitimate sites that have been compromised.

This represents an almost 50 percent increase over the previous six-month period.

• 60 percent of the top 100 most popular Web sites have either hosted or been involved in

malicious activity in the first half of 2008.

• 12 percent of Web sites infected with malicious code were created using Web malware exploitation kits, a decrease of 33 percent since December 2007. Websense researchers believe this decrease may be attributed to attackers launching more customized attacks to avoid signature detection by security measures.

Cybercriminals Increase Attacks on Web Sites with “Good” Reputations

 

During the first half of 2008, the volume of legitimate Web sites compromised with malicious code continued to surpass the number of sites created by attackers specifically for malicious purposes. In the first half of 2008 more than 75 percent of the Web sites Websense classified as malicious were actually sites with seemingly “good” reputations that had been compromised by attackers. This represents a 50 percent increase over the last six months.

Top 10 Web Attack Vectors in 1st Half of 2008:

1. Browser vulnerabilities

2. Adobe Flash vulnerabilities

3. ActiveX vulnerabilities

4. SQL injection

5. Adobe Acrobat Reader vulnerabilities

6. Content management systems (CMS) vulnerabilities

7. Apple QuickTime vulnerabilities

8. Malicious Web 2.0 components (e.g. facebook applications,

third-party widgets/gadgets, banner ads etc)

9. RealPlayer vulnerabilities

10. DNS cache poisoning

Over the last six-months, the volume of pornographic spam, decreased more than 70 percent while shopping increased by almost 80 percent.
