In the computer
security context, a hacker
is someone who seeks and exploits weaknesses in a computer
system or computer network. Hackers may be motivated by a
multitude of reasons, such as profit, protest, challenge or enjoyment.The
subculture that has evolved around hackers is often referred to as the computer
underground and is now a known community.While other uses of the word hacker
exist that are not related to computer security, such as referring to someone
with an advanced understanding of computers and computer networks,
they are rarely used in mainstream context. They are subject to the
longstanding hacker definition controversy about the
term's true meaning. In this controversy, the term hacker is reclaimed
by computer programmers who
argue that someone who breaks into computers, whether computer criminal (black hats)
or computer security expert (white hats), is more appropriately called a cracker instead.Some white hat hackers claim that they also deserve the title hacker,
and that only black hats should be called "crackers".
How are computer hackers and predators a threat to computer security?
People, not computers, create computer threats. Computer predators
victimize others for their own gain. Give a predator access to the
Internet — and to your PC — and the threat they pose to your security
increases exponentially. Computer hackers are unauthorized users who
break into computer systems in order to steal, change or destroy
information, often by installing dangerous malware without your
knowledge or consent. Their clever tactics and detailed technical
knowledge help them access information you really don’t want them to
have.
How do computer hackers and predators find me?
Anyone who uses a computer connected to the Internet is susceptible
to the threats that computer hackers and predators pose. These online
villains typically use phishing scams, spam email
or instant messages and bogus Web sites to deliver dangerous malware to
your computer and compromise your computer security. Computer hackers
can also try to access your computer and private information directly if
you are not protected with a firewall. They may also monitor your chat
room conversations or peruse your personal Web page. Usually disguised
with a bogus identity, predators can lure you into revealing sensitive
personal and financial information, or much worse.
What can computer hackers and predators do to me?
While your computer is connected to the Internet, the malware a
hacker has installed on your PC quietly transmits your personal and
financial information without your knowledge or consent. Or, a computer
predator may pounce on the private information you unwittingly revealed.
In either case, they may:
- Hijack your usernames and passwords
- Steal your money and open credit card and bank accounts in your name
- Ruin your credit
- Request new account Personal Identification Numbers (PINs) or additional credit cards
- Make purchases
- Add themselves or an alias that they control as an authorized user so it’s easier to use your credit
- Obtain cash advances
- Use and abuse your Social Security number
- Sell your information to other parties who will use it for illicit or illegal purposes
Predators can pose a serious physical threat. Use extreme caution
when agreeing to meet an online “friend” or acquaintance in person.
How will I know?
Check the accuracy of your personal accounts, credit cards and
documents. Are there unexplained transactions? Questionable or
unauthorized changes? If so, dangerous malware installed by predators or
hackers may already be lurking.
What can I do about computer hackers and predators?
When you arm yourself with information and resources, you’re wiser about computer security threats and less vulnerable to threat tactics. Hackers and predators pose equally serious and but very different threats.
To protect your computer from hackers and predators:
- Continually check the accuracy of personal accounts and deal with any discrepancies right away
- Use extreme caution when entering chat rooms or posting personal Web pages
- Limit the personal information you post on a personal Web pages
- Carefully monitor requests by online “friends” or acquaintances for predatory behavior
- Keep personal and financial information out of online conversations
- Use extreme caution when agreeing to meet an online “friend” or acquaintance in person
Take these steps to protect your computer from hackers right away:
- Use a 2 way firewall
- Update your operating system regularly
- Increase your browser security settings
- Avoid questionable Web sites
- Only download software from sites you trust. Carefully evaluate free
software and file-sharing applications before downloading them.
- Practice safe email protocol:
- Don't open messages from unknown senders
- Immediately delete messages you suspect to be spam
- Make sure that you have the best security software products installed on your PC:
- Use antivirus protection
- Get anti spyware software protection
An unprotected computer is like an open door for computer hackers and
predators. To take it a step further, protect your computer from
hackers by using a spam filter or gateway to scan inbound email or IM
messages. Products like Web root Spy Sweeper® and Web root Internet Security Essentials thwart dangerous malware
before it can enter your PC, stand guard at every possible entrance of
your computer and fend off any spyware or viruses that try to enter,
even the most damaging and devious strains. While free anti-spyware and
antivirus downloads are available, they just can’t keep up with the
continuous onslaught of new malware strains. Previously undetected forms
of malware can often do the most damage, so it’s critical to have
up-to-the-minute, guaranteed protection.
