Should we "dial-ups" be concerned?
Usually broadband users are the primary target. In this case, you could visit a web site whose server has been exploited and the HTML of that site would automatically download the malware. The trojans, keyloggers, and over 40 different malware can be in such small packets that you wouldn't notice the download. I am not an expert on this subject, but I think that is correct.
"First they were pushing Virtumondo adware," said Sites, "but by late afternoon yesterday, these sites were distributing more than 40 different types of malware, including keyloggers, adware, and backdoors."Other researchers spotted the exploit on popular shared hosting distribution sites. The current in-the-wild exploit generates a stack overflow as soon as the user views an HTML page; once that happens, the attacker can push whatever code he wants onto the PC. "We're seeing this on dozens of different sites," said Gunter Ollmann, the director of Internet Security Systems' X-force research lab.
