![]() ![]() The most unsophisticated method is spoofing, which is substitution of technical headers in messages. There are several ways to use valid details. In general, messages are mass mailed on behalf of an existing company, while the technical headers of fake messages use the company’s actual details. ![]() The way spammers organize their personalized attacks plays an important role as well. ![]() Of course, cybercriminals will not have very many of these addresses at their disposal (compared to generated addresses), but they are much more valuable. This information is sold to evildoers as ready-to-use databases with physical addresses (they are frequently offered for sale in spam messages), collected by evildoers from open sources, or obtained by evildoers when hacking email accounts, for example. Thus, in the malicious mailing that we discovered last month, spammers used the actual postal addresses of the recipients in messages to make them seem as credible as possible. Lately, however, we have been noticing an opposite tendency occurring quite often, wherein fraud becomes personalized and spammers invent new methods to persuade the recipient that the message is addressed personally to him. This impersonality, as a rule, attests toa phishing attempt. Any specifics that may help the recipient ascertain whether the message is addressed personally to him or not, for example, an existing account number, a contract number, or the date of its conclusion, is missing in the message. The most that personal data is ever involved is when the name of the mailbox (or part of it) is substituted with the electronic address that the spammer has. Generally, these kinds of messages do not personally address the recipient and are limited to common phrases such as “Dear Client”. Most spam, especially the sort that is mass-mailed on behalf of businesses, has quite an impersonal format: spammers create a message template for a specific mailing purpose and often drastically diversify the contents of that template. ![]()
