This page covers information for the safe and responsible use of Internet Relay Chat (IRC) and other "chat rooms". Maybe you were referred here because you suspect your security has been compromised, or maybe you just want to make sure you are safe. The following major topics are covered here:
Trojan Horse Attacks
Trojan horses are attractively disguised files which cause harmful consequences if you download and run them, e.g. takeover of your IRC channels, erasing of your hard disk, etc. Learn more about these attacks and how to undo the damage.
Denial of Service Attacks (Nukes)
- Denial of service attacks or "nukes" make networked computers disconnect or crash. Learn how to defend yourself against these attacks.
Downloading Files from IRC
- The biggest threat to IRC security ironically has nothing to do with the protocol or software itself. It is what people do with IRC, e.g. downloading of illegal files. This can lead to legal problems, trojan horse viruses, denial of service attacks, etc. For your own good, learn these hard facts about file trading.
- Technical discussion of problems involved with using IRC from behind a proxy, firewall, or NAT gateway. Includes links for specific fixes for identd and DCC problems.
General IRC Security [ext. link]
- This page describes why security is important on IRC, and provides general suggestions for how to secure your home computer/network.
Parent's Guides [all ext. links]
- Some sites with good information for parents to ensure their kids are chatting safetly and properly.
- GetNetWise: this public service is your one stop for helpful guides, blocking/filtering tools, how to report trouble, safe sites for kids, etc.
- FBI Library - Parent's Guide to Internet Safety: this short pamphlet from the FBI covers the safety issues with general suggestions.
- America Links Up: another broad coalition providing overall information, not as thorough as GetNetWise but uniquely offers teach-in events and discussion boards.
- Safe Kids: yet another overall help site, a little harder to navigate but has well written articles.
Backdoors in IRC
- Backdoors in IRC clients/scripts/bots allow others to gain unauthorized access to your computer to do harm to yourself or others. This guide illustrates the dangers of blindly using other people's scripts etc.
CIAC-2318 IRC On Your Dime? [ext. link to PDF file]
