Because spoofed email and Internet sites are becoming more and more sophisticated, phishing attacks are harder than ever to identify and defend against. To protect against becoming victims of phishers, security experts recommend that in addition to following general best practices for computing, users should visit sites such as www. Security experts also suggest that users should never disclose any confidential personal or financial information if they have doubts about the authenticity of an email or Web site.
Nowhere to Go. Information exposure threats can be present in almost any type of malicious code, including Trojan horses, worms, viruses, and back door server programs. Several worms and Trojan horses contain keystroke logging and back door functionality in addition to their other components.
Such threats have continued to increase since June , according to the Internet Security Threat Report.
Over the last half of , malicious code that exposed confidential information represented 54 percent of the top 50 malicious code samples received by Symantec-up from 44 percent in the first half of and 36 percent in the second half of This increase is partially due to the increasing proliferation of bots, which expose all information on a compromised computer due to their remote access capabilities. Bots-short for "robots"-are programs that are covertly installed on a user's computer in order to allow an unauthorized user to control that computer remotely.
Bots are designed to let an attacker create an entire network of compromised hosts, which can then be remotely controlled to conduct malicious activities collectively. Bots are a significant part of the trend of using malicious code for profit as spammers use the IP addresses of compromised home computers for relaying their messages.
Bots often employ multiple propagation mechanisms to compromise computers. Therefore, designers are advised to avoid using questionable peer-to-peer services, use strong password protection on shared network drives, and patch vulnerabilities in their operating systems and applications.
It is not surprising that client-side vulnerabilities are often implicated in information exposure breaches. Winter alcove fantasy background by indigodeep.
