GENERAL TIPS ON POSSIBLE INTERNET FRAUD SCHEMES

Don't Judge by Initial Appearances.
It may seem obvious, but consumers need to remember that just because something appears on the Internet - no matter how impressive or professional the Web site looks - doesn't mean it's true. The ready availability of software that allows anyone, at minimal cost, to set up a professional-looking Web site means that criminals can make their Web sites look as impressive as those of legitimate e-commerce merchants.

Be Careful About Giving Out Valuable Personal Data Online.
If you see e-mail messages from someone you don't know that ask you for personal data - such as your Social Security number, credit-card number, or password - don't just send the data without knowing more about who's asking. Criminals have been known to send messages in which they pretend to be (for example) a systems administrator or Internet service provider representative in order to persuade people online that they should disclose valuable personal data. While secure transactions with known e-commerce sites are fairly safe, especially if you use a credit card, nonsecure messages to unknown recipients are not.

Be Especially Careful About Online Communications With Someone Who Conceals His True Identity.
If someone sends you an e-mail in which he refuses to disclose his full identity, or uses an e-mail header that has no useful identifying data (e.g., "W6T7S8@provider.com"), that may be an indication that the person doesn't want to leave any information that could allow you to contact them later if you have a dispute over undelivered goods for which you paid. As a result, you should be highly wary about relying on advice that such people give you if they are trying to persuade you to entrust your money to them.

Watch Out for "Advance-Fee" Demands.
In general, you need to look carefully at any online seller of goods or services who wants you to send checks or money orders immediately to a post office box, before you receive the goods or services you've been promised. Legitimate startup "dot.com" companies, of course, may not have the brand-name recognition of long-established companies, and still be fully capable of delivering what you need at a fair price. Even so, using the Internet to research online companies that aren't known to you is a reasonable step to take before you decide to entrust a significant amount of money to such companies.

Internet Fraud

The term "Internet fraud" refers generally to any type of fraud scheme that uses one or more components of the Internet - such as chat rooms, e-mail, message boards, or Web sites - to present fraudulent solicitations to prospective victims, to conduct fraudulent transactions, or to transmit the proceeds of fraud to financial institutions or to other connected with the scheme.
If you use the Internet with any frequency, you'll soon see that people and things online tend to move, as the saying goes, on "Internet time." For most people, that phrase simply means that things seem to happen more quickly on the Internet -- business decisions, information-searching, personal interactions, to name a few - and to happen before, during, or after ordinary "bricks-and-mortar" business hours.
Unfortunately, people who engage in fraud often operate in "Internet time" as well. They seek to take advantage of the Internet's unique capabilities -- for example, by sending e-mail messages worldwide in seconds, or posting Web site information that is readily accessible from anywhere in the world - to carry out various types of fraudulent schemes more quickly than was possible with many fraud schemes in the past.

Major Types of Internet Fraud


In general, the same types of fraud schemes that have victimized consumers and investors for many years before the creation of the Internet are now appearing online (sometimes with particular refinements that are unique to Internet technology). With the explosive growth of the Internet, and e-commerce in particular, online criminals try to present fraudulent schemes in ways that look, as much as possible, like the goods and services that the vast majority of legitimate e-commerce merchants offer. In the process, they not only cause harm to consumers and investors, but also undermine consumer confidence in legitimate e-commerce and the Internet.


Here are some of the major types of Internet fraud that law enforcement and regulatory authorities and consumer organizations are seeing:


• Auction and Retail Schemes Online.

According to the Federal Trade Commission and Internet Fraud Watch, fraudulent schemes appearing on online auction sites are the most frequently reported form of Internet fraud. These schemes, and similar schemes for online retail goods, typically purport to offer high-value items - ranging from Cartier® watches to computers to collectibles such as Beanie Babies® - that are likely to attract many consumers. These schemes induce their victims to send money for the promised items, but then deliver nothing or only an item far less valuable than what was promised (e.g., counterfeit or altered goods).

• Business Opportunity/"Work-at-Home" Schemes Online.

Fraudulent schemes often use the Internet to advertise purported business opportunities that will allow individuals to earn thousands of dollars a month in "work-at-home" ventures. These schemes typically require the individuals to pay anywhere from $35 to several hundred dollars or more, but fail to deliver the materials or information that would be needed to make the work-at-home opportunity a potentially viable business.

Identity Theft and Fraud. Some Internet fraud schemes also involve identity theft - the wrongful obtaining and using of someone else's personal data in some way that involves fraud or deception, typically for economic gain.


  • In one federal prosecution, the defendants allegedly obtained the names and Social Security numbers of U.S. military officers from a Web site, then used more than 100 of those names and numbers to apply via the Internet for credit cards with a Delaware bank.


  • In another federal prosecution, the defendant allegedly obtained personal data from a federal agency's Web site, then used the personal data to submit 14 car loan applications online to a Florida bank.


Investment Schemes Online



o Market Manipulation Schemes. Enforcement actions by the Securities and Exchange Commission and criminal prosecutions indicate that criminals are using two basic methods for trying to manipulate securities markets for their personal profit. First, in so-called "pump-and-dump" schemes, they typically disseminate false and fraudulent information in an effort to cause dramatic price increases in thinly traded stocks or stocks of shell companies (the "pump"), then immediately sell off their holdings of those stocks (the "dump") to realize substantial profits before the stock price falls back to its usual low level. Any other buyers of the stock who are unaware of the falsity of the information become victims of the scheme once the price falls.


1) For example, in one federal prosecution in Los Angeles, the defendants allegedly purchased, directly and through another man, a total of 130,000 shares in a bankrupt company, NEI Webworld, Inc., whose assets had been liquidated several months earlier. The defendants then allegedly posted bogus e-mail messages on hundreds of Internet bulletin boards, falsely stating that NEI Webworld was going to be taken over by a wireless telecommunications company. At the time of the defendants' alleged purchases of NEI Webworld stock, the stock was priced between 9 cents and 13 cents a share. Ultimately, in a single morning of trading, NEI Webworld stock rose in 45 minutes from $8 per share to a high of $15 5/16, before falling, within a half-hour, to 25 cents per share. The defendants allegedly realized profits of $362,625.

2) In another federal prosecution in Los Angeles, a man who worked for a California company, PairGain Technologies, created a bogus Bloomberg news Web site which falsely reported that PairGain was about to be acquired by an Israeli company, and posted fraudulent e-mail messages, containing links to the counterfeit Bloomberg news site, on financial news bulletin boards. On the day that the bogus report was posted on the Internet, PairGain stock rose approximately 30 percent before PairGain issued its own press release stating that the report was false.


Second, in short-selling or "scalping" schemes, the scheme takes a similar approach, by disseminating false or fraudulent information in an effort to cause price decreases in a particular company's stock.



3) example, in one recent federal prosecution, a man who described himself as a "day trader" allegedly posted (more than 20 times) a bogus press release falsely stating that a major telecommunications- and Internet-related company, Lucent Technologies, Inc., would not meet its quarterly earnings estimates. The day trader allegedly traded approximately 6,000 shares of Lucent stock the same day that he posted the bogus press release. The false reports allegedly drove the stock's price down 3.6 percent and reduced Lucent's market value by more than $7 billion.
o Other Investment Schemes


Other types of fraudulent investment schemes may combine uses of the Internet with traditional mass-marketing technology such as telemarketing to reach large numbers of potential victims.



1) In a federal prosecution in San Diego, a major fraudulent scheme used the Internet and telemarketing to solicit prospective investors for so-called "general partnerships" involving purported "high-tech" investments, such as an Internet shopping mall and Internet access providers. The scheme allegedly defrauded more than 3,000 victims nationwide of nearly $50 million.
• Credit-Card Schemes.


Some Internet fraud schemes, which appear to be variations on the online auction schemes described earlier, involve the use of unlawfully obtained credit card numbers to order goods or services online.



1) One widely reported and intricate scheme, for example, involves offering consumers high-value consumer items, such as video cameras, at a very attractive price (i.e., below the price set at legitimate e-commerce Web sites). When a potential consumer contacts the "seller," the "seller" promises to ship the consumer the item before the consumer has to pay anything. If the consumer agrees, the "seller" (without the consumer's knowledge) uses that consumer's real name, along with an unlawfully obtained credit card number belonging to another person, to buy the item at a legitimate Web site. Once that Web site ships the item to the consumer, the consumer, believing that the transaction is legitimate, then authorizes his credit card to be billed in favor of the "seller" or sends payment directly to the "seller."

As a result, there are two victims of the scheme: the original e-commerce merchant who shipped the item based on the unlawfully used credit card; and the consumer who sent his money after receiving the item that the "seller" fraudulently ordered from the merchant. In the meantime, the "seller" may have transferred his fraudulent proceeds to bank accounts beyond the effective reach of either the merchant or the consumer.



• Other Schemes.


Some Web sites on the Internet have purported to offer those who want a "quick divorce" an opportunity to obtain a divorce in the Dominican Republic or other foreign countries for $1,000 or more, without even having to leave the United States. These sites often contain false, misleading, or legally inaccurate information about the process for obtaining such divorces (e.g., that neither spouse has to visit the country in which the divorce is being sought). Typically, people who have sent money to one of these schemes eventually receive false assurances that they are legally divorced. In fact, victims of the scheme have neither received legitimate legal services nor obtained valid divorces. People who are interested in obtaining a divorce, whether in the United States or elsewhere, should seek a lawyer with whom they can speak personally, and not rely solely on e-mail exchanges or online information.

About 3G


3G Technologies

-
3G technologies enabled faster data-transmission speeds, greater network capacity and more advanced network services. The first pre-commercial 3G network launched in May 2001 by NTT DoCoMo in Japan. The network was branded as FOMA. Following the first pre-commercial launch, NTT DoCoMo again made history with the first commrcial launch of 3G in Japan on Oct. 1, 2001.


The 3G technologies permit network operators a bigger repertoire of offerings to the public, at the same time having a bigger capacity via spectral performance. These services cover wide-area telephony and wireless data (broadband). Ordinarily, they would give services of 5 to 10 MB/second, but the emphasis is 'ordinarily'.
The 3G Network is a cell telephone network, and later on it embraced internet access, plus video telephony too. Very recently, December of last year, 190 3G network entities were running in forty nations, while 154 HSDPA networks were running in more than 70 countries. At Canada, Europe, USA, and Asia, the telecom firms utilize W-CDMA technologies, and they were supported by more or less 100 terminals for the 3G mobile systems.
Let us go to Europe, in this part of the world, 3G offerings got introduced in March, 2003 at Italy and the UK. Networks' rollout was affected (delayed) in some nations due to the big costs of licensing charges. For many nations, the 3G do not utilize the 2G's radio frequencies, thus, the operators have to erect new ones. Also, there were other delays, caused by the costs of upgrading for a new system.
Technical nature of the
3G mobile phones would all depend on the necessity for roaming to the 2G systems. As far as the leading countries are concerned, like South Korea or Japan, there was no such pressing need. Thus, the 3G phones or sets were small. That was not the case for America/Europe, manufacturing entities desired the multi-mode 3G handsets that could run on both 2G and 3G, one example would be the WCDMA. This would mean more weight, bulk, complications and naturally, the costs.
While this could be construed as a relative statement, many experts believe that the general inclination toward tinier phones has been stopped for a while. This is due to the presence of big-screen handsets that could give more gaming, video and even Internet access.
It could be said that the number one feature of the 3G is : it allows for a bigger number of data/voice customers, particularly from the urban territories. Not just that, higher data profiles at smaller incremental expenditures compared to the 2G systems.
The 3G network also permits the transmission of the 384 kbit/s to the mobile units, also, the 2 mb/s to the systems which are stationary.
How do we see all this 3G being applied in our daily lives? Well, number is the favorite of the married women, shopping- and translates to e-shopping. Think of it, one using his/her 3G phones or phone to access his bank account, and while in there, he would settle some bills. Not just that, he could then have a video-conference at the same time.
Let us assume that you are going to the South of France, those 3G phones could acquire the tour guides, or be used for the hotel reservations.

About Pen Drives


Advantages and Disadvantages of Pen Drives

Advantages of pen drives are that they are resistant to scratches and dust. Some pen drives are water proof and can function even after being submerged in water. Their solid-state design means they often survive casual abuse. They are ideal for transporting personal data or work files from one location to another. The near ubiquity of USB support on modern computers makes it work everywhere. Pen drives have immense storage capacity and even inexpensive ones will hold lots of data. Top of the line pen drives have 64 GB storage. Power consumption of a typical flash drive is very low. Pen drives have no moving parts meaning that most modern operating systems can read and write to flash drives without any additional device turners. Pen drives are much more tolerant of abuse than mechanical drives.

Disadvantages are that they can sustain limited number of write and erase cycles before failure. Mid-range pen drives under normal conditions will support several hundred thousand cycles, although write operations will gradually slow as the device ages. Most USB pen drives do not include a write-protect mechanism. Write-protection makes a device suitable for repairing virus contaminated host computers without risk of infecting the USB flash drive itself. A drawback to the small size is that they are easily misplaced or lost. This is a particular problem if the data they contain are sensitive. It is for this reason that pen drives are now coming attached to key chains, necklaces and lanyards. They have limited capacity when compared to disk drives even in 2.5inch form factors. They get damaged or data is corrupted by severe physical impacts. Improperly wired USB ports can also destroy the circuitry of pen drives. Pendrives are costly .
