Communication over the network with advertisements (advertised address removed)

Sometimes spam distribution network via the built-in Microsoft Windows SMB-service Messenger. These messages appear as pop-ups (unless a third-party software, manufacturing them in other ways). In this case, to turn off their admission may be, for example, to stop the Messenger service using net stop messenger [12]. In versions of Windows NT, beginning with Windows XP SP2, this service has already stopped by default, so this method of distribution are less likely to occur.

SMS-messages

Spam can be spread not only through the Internet. Advertising messages sent to mobile phones via SMS-messages, especially the unpleasant fact that they are difficult to defend.

Collect email addresses

Spammers find out the email addresses of users in different ways. Some of them are:
Address mailbox user posted on the public site ? mostly in the guest book, forum, personal card, etc., where it can find a special program (harvester), Scanning indexing sites such as search engine robots.
If the address of the mailbox is not unique word, for example, common name, it may be chosen for the dictionary. Do spammers have special dictionaries that include common words, names of people, place names and some of the most popular combination of network slang. Combining this dictionary and a list of domain names (open public), a spammer gets a list of addresses for mailing.
If you are a person with whom the owner of this correspondence box was infected with a Trojan program, all the addresses from its address book can get to a spammer.
The database of customers a company could be stolen or even sold by the company spammers. Read the rest of this entry »

Ideology

It is clear that spam brings economic benefits to its customers. This means that users, despite the dislike of spam, does enjoy the services advertised through spam. Until the impact of spam exceeds the cost of overcoming protection, spam will not disappear. Thus, the surest way to fight a denial of service advertised through spam. There are proposals on the use of public condemnation, until the end of communication, against those who buy spam advertised goods and services.

Other methods are aimed at inhibiting the spammers access to users.

Preventive measures to protect

The surest way to fight spam ? do not let spammers get e-mail address. This is a difficult task, but some precautions can be taken.
Do not publish your email address on public websites.
If for some reason the email account to publish, it can be coded like ?u_s_e_r_ (a) _d_o_m_a_i_n_._n_e_t?. Spammers use special programs to scan websites and collect email addresses, so even a masking addresses can help. It should be remembered, however, that in the simplest cases ?encoded? will be able to recognize and address of the program. In addition, it is an inconvenience not only for spammers, but also for ordinary users. Read the rest of this entry »

Black lists

Ownership, use, efficiency
These include:
lists of IP-addresses of computers that are known to them being spam.
(widely used) lists of computers that can be used for distribution ? ?relei open? and ?open proxy?, and also ? lists ?dial? ? client addresses to which there can be no mail servers
(possible use), a local list or the list maintained by someone else.
(widely distributed through the simplicity of implementation), black lists, a request that is carried out via DNS. They are called DNSBL (DNS B lack L ist). Currently this method is not very efficient. Spammers find new computers to their goals faster than they manage to enter in the black lists. In addition, several computers, send spam, can compromise the entire email domain, or subnet, and thousands of law-abiding users for an indefinite period will be denied the opportunity to send e-mail servers, using a black list.
(found) lists rather preach radical theory (eg, equating to a viral malicious spam messages, etc.). Read the rest of this entry »
