Phishing & Spam – how to identify fake customer communication via e-mail

Cyber criminals are using more and more treacherous methods to permanently damage web service users. A very popular method is through the use of fake e-mail that at first glance seems like real customer communication. These types of emails mimic service providers by sending alleged bills or other official-looking notifications to recipients who are then asked to follow a link to a website, where they are asked to provide sensitive information such as passwords or payment information. With this information, cyber criminals can access customer data for criminal purposes and inflict financial harm. There can also be hidden malware in attached files, which infect a user’s computer once opened. In recent cases, cyber criminals have evolved their tactics by sending phishing e-mails claiming to close a user’s account. Should the reader fall for the scam and enter their login information on a fake website, the email and password may end up being released to other spam mailing lists.

How E-mail Spam is Identified

E-mail is one of the oldest and most-used services on the internet, so it is understandable how much of an inconvenience it causes users when messages are blocked or not sent.

E-mail providers work hard to use the time and resources necessary to prevent spammers in their systems and protect other users. In order to make this an easier process for a Mail Server Administrator, they use organizations which create RBLs, or Real-time Black Lists. These lists make it easier for IT professionals to query potential SPAM sources for their mail servers and thus protect their users. These systems are not perfect, however, and sometimes an IP address can be listed by mistake.

1&1 uses feedback from these services and blacklists to identify spammers in our own network. Prevention of hacking, and education for our customers on how to secure their servers, are two of the most important services we aim to provide. Unfortunately, sometimes legitimate business customers are sharing the same mail servers with illegitimate spammers, causing them to be incorrectly blacklisted by these organizations.

These issues are typically resolved by isolating the offending spammer and getting the mail servers removed from the blacklists.
