Java, Adobe vulns blamed for Windows malware mayhem « The Register Failure to patch third-party applications has become the main reason that Windows machines get infected with malware
Drive-by download attacks from hacker-controlled websites loaded with exploits replaced infected email attachments as the main distribution method for malware somewhere between three to five years ago. At the start of this period browser exploits were the main stock-in-trade for VXers but this has changed over time, as a study by Danish security firm CSIS and published on Tuesday illustrates.
Up to 85 per cent of all virus infections happen as the result of drive-by attacks served up via commercial exploit kits, CSIS reports. The security consultancy, which specialises in e-crime research, monitored the behaviour of 50 different exploit kits over a period of three months, analysing the causes of infection of both commercial and consumer systems.
The study discovered that 31.3 per cent of 500,000 users who were exposed to exploit toolkits were secretly force-fed malware as a result of missing security updates. Systems running vulnerable versions of Java JRE, Adobe Reader and Acrobat, and Adobe Flash were particularly at risk of attack
. Vulnerabilities in Internet Explorer, by contrast, only cropped up in 10 per cent of attacks. By contrast, Java flaws (37 per cent), Adobe Reader/Acrobat (32 per cent) and Flash (16 per cent) were far more productive routes towards exploit. Apple QuickTime holes were poked in two per cent of attacks. Infected systems are typically loaded with a cocktail of malware, often including fake anti-virus software (AKA scareware) and information-stealing spyware. (Source
