Special Security Edition
Editor's
note: This month begins a continuing series focusing on security and
other important concerns in our cyber world. Stay with us for
information that may help keep you safe and secure in months to
come. . .
Find out how "Security Aware" you are!
Do you believe you're a little more Security Aware? Can you identify
the threats that exist in your environment and the steps you should
take to avoid them? Take the following quizzes and find out.
Firewall Foibles
Myth: I've heard that hardware firewalls are better than software
firewalls.
Fact: Hardware and software firewalls provide different
protections for your computer, which make it a good idea to have
both. If you have DSL (digital subscriber line), for example,
chances are good that your DSL modem also acts as a basic hardware
firewall; it makes your system invisible to the Bad Guys out there
prowling around on the Internet. "Security by obscurity" is an
important primary defense, but many kinds of viruses, worms, and
spyware can get past this kind of protection. A software firewall,
your best secondary defense, should be ready and waiting to stop the
malware before it gets loose in your computer where it can both
compromise your personal information and begin attacking other
networked computers.
Myth: I know that my
DSL modem is also a hardware firewall, and I have the Windows
firewall turned on, so I don't need a separate software firewall.
Fact: With a basic hardware firewall in place and the Windows
firewall turned on, your system is protected against hacking
attempts from the Internet and the ill effects of many varieties of
malware. But the Windows firewall is one-directional; it only
defends your computer against incoming attacks. Your computer can
still get infected via other means such as infected e-mail
attachments. If it does, your computer may start acting out and
attacking other networked computers, also without your knowledge. A
two-directional firewall will help quash outgoing attacks directed
at other computers as well incoming ones directed at your computer,
and serves to alert you that your computer has become infected so
you can take the steps to correct the problem.
Current scams, malicious email and hoaxes:
Bank, Credit Union,
Pay-Pal, and eBay Phishing Scams
Bait: As we reach the end of summer 2007, these email
phishing scams are fewer in number, but are still going strong.
Remember that banks, credit unions, Pay-Pal, and eBay never send out
emails asking account holders and members to provide or verify
personal information. If you do get one about an institution you
belong to, you should call them.
Fake E-card Emails
Beget Fake Membership Emails
Bait: Emails claiming that you have received a free, temporary
membership in a website providing resume listings or cellphone
ringtones. The criminals responsible for the fake e-Card
messages changed tactics and began distributing these bogus
membership confirmation emails in August. The login link in the
email actually points to a dirty website that attempts to install
yet another Trojan. It may also attempt to trick you into manually
installing malware components. The bogus web page may contain a
message similar to the following: If you do not see the Secure
Login Window please install our Secure Login Applet.
Don't fall for any of it.
Bum_tnoo7 Hacker
Warning Hoax
Bait: Emails claiming that "bum_tnoo7@hotmail.com"
is the address of a hacker and simply by accepting the address into
your instant messaging contact list, you will allow the hacker
access to your computer. The warning has been rapidly circulating
around social networking communities such as Facebook and MySpace
and is also travelling via instant messages and email. This warning
is bogus and should not be taken seriously. The message is, in fact,
nothing more than a spin-off of the long running MSN contact list
virus hoax.
Infostealer.Monstres,
a Trojan that installed itself on many users' computers, has stolen
over 1 million records from the Monster.com job search website's
database, including the name, email address, home address and phone
numbers of several hundred thousand job-seekers, based mostly in the
United States.
Editor's Note: If you didn't read Section One of this issue on
Firewall Foibles, go back and read through it. This is an excellent
example of why you want a two-directional firewall on your machine.
Storm Worm,
a worm that spreads by infected email attachments, began spreading
and creating botnets in January. Many variants that have appeared
since then make it a tough security opponent. The latest targets
have been colleges and universities. The malware's latest trick is
to strike back at the computers pressed into service to scan
networks and remove the worm. (See also Security Newsbytes below.)
VirusProtectPro,
a Trojan masquerading as an anti-virus and anti-spyware product
installs itself on your computer without your permission and creates
a series of pop-ups suggesting that you need to purchase more
products like it.
Editor's Note: This imaginative malware has all the elements
of well done IT parody – no exotic name, no unexpected attachment,
no bogus claim on how to make money, just a "straightforward" offer
to protect yourself from Bad Guys, expressed in language that
ordinary computer users understand and are accustomed to: "Virus",
to get your attention; "Protect" to reassure you; and "Pro" to
suggest that it is the Real Thing.
YouTube and You Lose
A hacker group known as "Storm Botnet" began flooding the Internet
over the weekend with emails, inviting Web users to watch a
salacious video starring them on YouTube, the video-sharing site
owned by Google. However, links in the emails actually point to
attacker-operated sites that try to download several malicious
programs onto vulnerable personal computers. Once infected,
victimized PC's become spam machines, "zombies" that Storm Botnet
can use to attack other computers. The attackers also plant a
rootkit in victim PCs that tries to hide the malicious programs so
antivirus software can't remove them. (See also Malware above)
Insecure Security
Products
Several anti-malware vendors have issued security updates for their
products recently. The highest-profile fix was by Trend Micro, which
patched numerous flaws in its ServerProtect, Anti-Spyware, and PC-cillin
products. CheckPoint Labs also fixed a serious vulnerability in
their ZoneAlarm products—a privilege-escalation error could allow
attackers to disable the software or gain unauthorized access to the
system. Finally, ClamAV, the open-source security software recently
acquired by SourceFire, recently added fixes for denial of service
and other bugs. |
