2o7.net
While checking a firewall's logs, I noticed a "TCP FIN SCAN" entry for
66.235.139.18. The log entry showed the local host accessing port 80 on the
remote host at that IP address. Out of curiosity, I performed an nslookup on
the IP address. The
PTR record for the IP address points to the 2o7.net
domain
name.
C:\>nslookup
Default Server:
Address: 192.168.0.1
> 66.235.139.18
Server:
Address: 192.168.0.1
Name: *.112.2o7.net
Address: 66.235.139.18
>
When I put
http://2o7.net in the address bar of a browser,
I was taken to a
Adobe Marketing Cloud privacy web page, which states:

Check a Domain's Reputation
There are a number of companies that provide a means of checking
a domain's reputation. E.g., perhaps you may wish to determine if a particular
domain name is associated with the transmission of spam or want to know whether
it is safe to visit a particular website. Often antispam and antivirus vendors
will allow you to lookup an IP address or
fully qualified domain name (FQDN)
, e.g.
somesite.example.com
to make that determination through
a website they provide.

Did Al Gore Say He Invented The Internet?
The answer is "no". He did make a statement in an interview with Wolf Blitzer
of CNN about his role in the creation of the Internet, but that statement
was taken out of context to be used as a political attack tool. I've heard
Al Gore mocked many times for his supposed statement and found someone else
making what appeared to be a sarcastic comment in a post today to an
article "
The
Web back in 1996-1997"
As I posted there, I would like to point out that he never claimed to have
invented the Internet
(see the Snopes article "Internet of Lies"). For
a much fuller discussion of the topic and some history on
the Internet’s development and Gore’s role in
supporting advanced networking initiatives, I would recommend
“
Al Gore and the Creation of the Internet”
His early vision of its potential and his support for funding
of advanced networking activities was important. Vint Cerf,
who has, I think appropriately, been dubbed the “father
of the Internet” for his technical contributions, along
with Bob Kahn, in designing the Internet Protocol, has credited
Gore’s early support for advanced networking efforts (see "Vint Cerf responded to MSNBC").
I see the same tactic of taking an opponent’s statements
out of context being widely used in the current campaign by both
parties. Unfortunately, I suspect many Americans will make up their minds
based on what they see in political ads that are designed to mislead
them. The tactic used so successfully against Gore still works.

IP and Domain Name Reputation Sites
An
IP address may be added to a
DNS Blacklist (DNSBL), if spam
is detected as emanating from that IP address. You can check for the presence
of an IP address on various blacklists using the
MxToolBox Email Blacklist
Check, which currently checks 124 blacklists, or at individual
blacklist sites, such as
MAPS.
You can check on whether an IP address has been associated with attacks
on other systems at DShield
or myNetWatchman by
performing an IP lookup.
You can also obtain information on the "reputation" for a site
at Barracuda
Central by performing a lookup on either an IP address or a domain name.
Barracuda Networks sells widely used spam firewall devices, so a poor
reputation listing at Barracuda Central may lead to email from an IP address
listed there, or with a domain name in the body of email messages being found
there, being blocked by those using Barracuda Networks security devices.
Another reputation site is
TrustedSource. You can lookup an IP address there and see a graph
of activity associated with that site. If you see red bars on the
graph, those represent malicious activity associated with the IP address
on the days for which those bars appear.

Locating Cybersquatters Capitalizing on a Variant of Your Domain
Cybersquatters
may buy domains similar to yours hoping to take advantage
of someone mistyping your domain name or to mislead someone into thinking
a domain name in a URL belongs to a legitimate company or organization.
For instance many people might visit microsoft.com, so a cybersquatter might
buy micrsoft.com, which has a missing "o", so that someone making a typo that
left out that "o" would be directed to the cybersquatter's site instead, where
the cybersquatter may have nothing but ads, hoping to get money generated
from those viewing those ads. If millions of people visit microsoft.com every
week, the cybersquatter will probably get a signifiant amount of traffic
from such a typo.
Or perhaps you own example.com. The cybersquatter may purchase example.net,
if it is available. Someone seeing example.net in an email may think the
domain belongs to your company and visit a site that might have nothing but ads,
perhaps even risque ones, or the site might try to infect visitors with
adware/spyware, which might harm your company's reputation, even though you
don't own the domain name and have no control over the site.
CitizenHawk helps you locate
potential cybersquatter sites for your domain name.

Checking on Whether a Remote System is an Oracle Server
Nmap can be used to determine if
a system is functioning as an Oracle server using the command
nmap -p 1521 -P0 -sT <ip_address>
.
Port 1521 is a port used by
Oracle server software, but the port may also be used by other software,
so, if nmap reports the system is listening on that port, it does not
guarantee that the system is an Oracle server.
The options specified above are as follows:
-p <port ranges>
This option specifies what ports you want to query.
-P0 Do not try and ping hosts at all before scanning them. This
allows the scanning of networks that don't allow ICMP echo
requests (or responses) through their firewall.
-sT TCP connect() scan: This is the most basic form of TCP scanning.
The connect() system call provided by your operating system is
used to open a connection to every interesting port on the
machine. If the port is listening, connect() will succeed,
otherwise the port isn't reachable. One strong advantage to this
technique is that you don/t need any special privileges. Any
user on most UNIX boxes is free to use this call.
For a list of other ports used by Oracle, you can check
Which TCP/UDP port or ports does 'oracle' use?

Happy Birthday Internet!
Reckoning by the publication of the first Request for Comment (RFC) document,
the Internet was born April 7, 1969, when
RFC 1 Title: Host Software was
published by Steve Crocker.
RFC's
document the protcols on the Internet. The precursor to today's Internet was
the ARPANET, which was
developed for the United States Department of Defense. The first RFCs were
published in 1969 for the ARPANET. At first researchers distributed hard
copies of the RFCs among themselves, but in December of 1969 they began
distributing them using the ARPANET itself.

AOL Cuts 5,000 Jobs
AOL plans to cut about 5,000 jobs within 6 months as it tries to move away from
its dwindling subscription dial-up service. AOL is planning to offer its
services for free to broadband users, counting on advertising revenues to
sustain it.
AOL's user base has been dwindling as users move to broadband services. Those
that don't have access to broadband services or don't want to pay for
broadband services are also likely to choose cheaper dial-up services
rather than pay a premium price for AOL's ad-saturated dial-up service.
