The Information You Need For An Accurate Moving Service Quote

The Information You Need For An Accurate Moving Service Quote

When you are looking for a moving service quote, you will want to make sure that you are entering the most accurate information. If you enter the information that is incorrect, it can affect your final outcome. The best policy for an accurate quote is to make sure that you have all of your information before you begin.

The first thing that you want to do is find out what information will be needed for the quote and then make sure that you have this information handy. If you skip a step because you do not have the information, it can affect the outcome of your quote.

There are many factors that can affect the price of your move. If you have stairs in your home, you may not realize that this may increase the price a bit. Movers have to work much harder when they have to travel on stairs and this is why you can expect to pay a bit more if you have stairs in your home.

Many large pieces of furniture are something else that you may want to consider when you are filling out information for your moving quote. If you have delicate or glass items this is another consideration. A piano is something that you will always want to disclose up front as this may need special considerations.

If you can schedule a move during the week rather then the weekend, you may be able to save some money and this is information that you may want to include for your quote.

You may be tempted to lie on your information to get a better quote, but this can backfire and you will be charged for the actual move, rather then the information you submit on a form. Being open from the beginning will make a big difference and you will know exactly what to expect.

There are many steps to a moving service quote and the more information you can provide, the more accurate the quote will be. You can pay a price that you expect and this can help you to have the most reasonable move for your money.

Save Money on an Extended Car Warranty Service Contract by Getting a Quote & Buying Direct

Save Money on an Extended Car Warranty Service Contract by Getting a Quote & Buying Direct

If you’re looking to save crazy money on an extended warranty, use the net to compare different coverage that are available. Dealerships markup the rates on the extended warranties in order to make a profit. They overcharge so much, usually hundreds or thousands more than what the actual warranty company charges. Then to make things worse, the used car extended warranty offered through the dealer isn’t even worth it. Many buyers don’t even get enough coverage for all of the money they’re spending.

This happens smoothly for the dealer because they don’t really explain the extended warranty to the used car buyers. Now, the shoppers are unable to make a conscious decision on their buy. So with dealers like this, how can we know if we’re getting a good deal or not? Most of the time, dealers won’t present all of the paperwork, so the car buyer doesn’t get to read over everything, which is completely unfair. Now, the customer doesn’t know of the deductible they’re obligated to or what parts of their car are actually covered.

To avoid going through all of this, you can search around online for extended warranty companies and their quotes. Some sites will allow you to compare them side-by-side in order to see what the best deal is. All you need is the make, model, year and miles on the car you’re getting a warranty for — next you’ll have a page filled with quotes and benefits to compare. With the internet you have access to tons of deals on used car warranties. Make an educated decision on which to pick before choosing any one of them. Shop around as much as you can to ensure that you’re getting the best coverage for the lowest rate.

Strathclyde Anti-phishing As A Web-based User Service Scam

Strathclyde Anti-phishing As A Web-based User Service Scam

Strathclyde University Associates – This paper describes the recent phenomenon of phishing, in which email messages are sent to unwitting recipients in
order to elicit personal information and perpetrate identity theft and financial fraud. A variety of existing techniques for
addressing this problem are detailed and a novel approach to the provision of phishing advice is introduced. This takes
the form of a Web-based user-service to which users may forward suspect email messages for inspection. The Anti-
Phishing Web Service rates the suspect email and provides a Web-based report that the submitter may view. This
approach promises benefits in the form of added security for the end-user and insight on the factors that are most
revealing of phishing attacks. Keywords detail as Phishing, spam, email scams.

Strathclyde University Associates Introduction. Phishing scams are an increasingly common method of identity theft. They begin with an email message that
appears to originate with an established legitimate organization. The email usually asks the recipient to
submit personal information on a website. However, the email is fraudulent and has actually been sent with
criminal intent. Unfortunately, many email users are unsophisticated in the ways of email and being unable to
spot phishing attempts, they innocently follow the instructions contained therein. A consequence of this
innocence may be significant financial loss.
This paper describes the nature of phishing scams and the associated problems email users face in
identifying phishing emails. In addition, we describe a software solution (the Anti-Phishing Web Service)
that aims to assist with the phishing problem.

Email, spam and scams on Strathclyde University and SCER Associates. The term spam commonly refers to unsolicited bulk email. Unsolicited email includes sales and job
enquiries specifically addressed to a particular recipient without their prior knowledge or request. Bulk email
includes mailing lists and newsletters to which the recipient has subscribed. Spam is the intersection of these
email varieties it is both unsolicited and bulk.
The majority of spam emails advertise products such as computer software or drugs. With negligible cost
and effort required to send spam, it now accounts for around 76% of all email messages (Gaudin, 2004).

Many infrequent email users now find it difficult to locate legitimate email in their mailbox. As a result, the
effectiveness of email as a communication medium has been severely reduced.
To combat this growing problem, most Internet Service Providers (ISPs) prohibit the sending of spam
from their networks. Some spammers use multiple free ISP accounts to send spam, whereby, if one of these
free accounts is terminated, another can be quickly created. Another popular method of despatching spam is
through virus infested PCs, usually belonging to unsuspecting home broadband users (Leyden, 2004a).
Despite attempts to reduce the problem, the incidence of spam continues to increase.

Many countries, including the UK and the US, have introduced laws to prevent the sending of spam (BBC
News, 2003). However, these laws have had little effect, since most spam originates from outside the
legislating country. There are also loopholes and inadequacies in these laws. For example, the US Can Spam
Act requires individuals to opt-out of spam, rather than opt-in. EU anti-spam laws also have problems,
because business email addresses are exempt from the legislation.

Since most legal attempts to address spam have met with limited success, many ISPs and email users now
rely heavily on email filters to remove spam. Spam filters perform a series of tests on each incoming email
and combine the results to determine whether the message is spam or legitimate. Spam filtering takes place at
the mail transfer agent (MTA) or mail user agent (MUA). Popular MTA spam filters include SpamAssassin
and Brightmail. Many MUA, such as Eudora and Mozilla Mail, now provide integrated spam filters. Without
spam filters and related spam blacklists many users might otherwise simply abandon the use of email.
While the majority of spam emails are advertisements for products, some messages aim to entice the
recipient into scams. Common email scams include pyramid schemes that promise very high returns on an
initial investment (Wikipedia, 2006a). Unfortunately, such investors have no chance of receiving any return
on their initial outlay. Perhaps the most popular email scam is the Nigerian money transfer (Wikipedia,
2006b). This scam asks the recipient for help with the transfer of money from a Nigerian bank account,
promising a large payment in return. Once entered, the investor is asked for sums of money to help with the
fictitious transfer process. Of course, no money transfer is ever received by the unwitting subjects of this
criminal operation.

Strathclyde The Anti-phishing Scam Web Service

Strathclyde The Anti-phishing Scam Web Service

Strathclyde University Associates anti-phishing web service by Christopher Cranston, Department of Computer and Information Sciences, University of Strathclyde, Glasgow.

Although there are existing anti-spam and anti-phishing solutions for end-users, none of them are widely
deployed or fully effective. Rising financial losses and a growing numbers of phishing attacks have led to
anti-phishing extensions to existing Web browsers, but there is little product attention on helping end-users
determine whether a received email is a phishing attempt. This often leaves users relying on their own
judgment when assessing the authenticity of an email.

In this context, we have prototyped an Anti-Phishing Web Service (APWS). This facility analyses users’
emails and advises if they are likely phishing attempts. The APWS operates in a three step process: (1) Users
forward any suspect email to the APWS for analysis; (2) The APWS performs a series of tests on the email,
each resulting in a score. An overall score is derived which indicates a likelihood that the email is a phishing
attempt; (3) The APWS generates an online report for the user.

The APWS has several advantages over existing end-user anti-spam and anti-phishing solutions. Firstly,
the APWS helps the end-user decide if an email is a phishing attempt by applying sophisticated analysis
techniques. Without assistance, users would otherwise have to judge whether an email is genuine using
whatever limited knowledge they may have. Secondly, the APWS may be combined with a spam filter. The
spam filter can attempt to catch all spam and phishing emails. Any emails which pass through can still be
sent to the APWS for analysis. Thirdly, the APWS has no reliance on a database of phishing attempts. This
means that new, un-encountered phishing attempts may be caught. Fourthly, the APWS operates as a network
service and requires no software installation on the users machine.
The goal of the APWS is to determine whether or not an email is a phishing attempt. To achieve this, it
relies on a collection of real phishing emails that were analysed as a basis for test design. Once the tests have
been applied, a report is generated on the results. The systems report function writes out the following email
headers to the html report file: From, To, Date Sent and Subject and adds the total score and corresponding
phishing risk rating for the email in question. The total score of an email begins at 0. Every test that returns
true adds 1 to the total score (this could be altered to weight some tests more than others). A phishing risk
rating is assigned according to the total score for the email.

Strathclyde University Associates anti-phishing web service – The content of test emails is parsed by the APWS in order to check all links, anchor tags and form tags.
Evaluating the credibility of a submitted email is largely heuristic, with a series of seventeen tests applied to
the email message in order to derive its final score. An outline of these tests is given below.
Phishing emails often contain URLs with encoded characters in an attempt to disguise the true link target.
We apply a test on every embedded Web link which returns true if the authority part of the URI contains
encoded characters. Similarly, a test checks each Web link and returns true if the user-info part contains
encoded characters. If the path part, the query part or the fragment part of Web link contains encoded
characters, each of these contributes a positive score to the message result.

A further common ploy in phishing emails is the use of URLs in which the host part is a dotted quad IP
address as an attempt to disguise the true URL. We check each URL for this feature and increment the
positive score if the result is true. Similarly, a positive value is added for any URLs in which the host part is
an IP address expressed as a single decimal number, and for URLs in which the host part is a dotted quad IP
address, with each quad expressed either in octal or hexadecimal.
Emails containing URLs with user-information in the authority part of the URL are often attempting to
obscure the true target, and make it appear as if the link points elsewhere. We test every embedded URL and
return true if the authority part contains user-information. Another tactic used to disguise the true destination
of a Web link, is to use URLs with user-information in the authority part of the URL, and in addition the
user-information itself resembles a URL. We test every URL for this feature and return true if the authority
part has user-information that resembles a URL. Embedded URLs that specify non-standard Web ports are a
further hint of irregularity. For any URL in which the port is not 80, we return an additional positive
increment.
The presence of a URL in which the organization domain contains the purported sender’s organization
domain as a substring, is a futher positive score since this is considered an attempt to disguise the link’s true
target. Similarly, URLs in which a subdomain matches the purported sender’s organization domain returns a
positive increment. If a URL has an organization domain that closely matches the purported sender’s
organisation domain, we also increment the positive score. This test is performed on every URL and returns
true if the Levenshtein Distance (LD) between the organization domain and the purported sender’s
organization domain is less than half the length of the purported sender’s organization domain. We do not
return true if the LD in this calculation is zero (i.e. the domains being compared are equal).
Phishing emails often contain anchor tags wherein the text the anchor text resembles a URL, but that
URL points to a different location than the tag’s href attribute. We returns a positive increment for URLs
with such a feature. Finally, we check for attachments with malicious content. This test is performed on every
attachment object and returns a positive increment if the attached file name extension matches one of the
following: ade, adp, bas, bat, chm, cmd, com, cpl, crt, exe, hlp, hta, inf, ins, isp, js, jse, lnk, mdb, mde, msc,
msi, msp, mst, pcd, pif, reg, scr, sct, shs, url, vb, vbe, vbs, wsc, wsf and wsh.
