Email Spoofing

E-mail spoofing is e-mail activity in which the sender address and other parts of the e-mail header are altered to appear as though the e-mail originated from a different source. Because core SMTP doesn't provide any authentication, it is easy to impersonate and forge emails.

Though it can be legitimate, it is usually fraudulent. Because the purpose is so often malicious, "spoof" (an expression whose base meaning is innocent parody) is a poor term for this activity which can confuse newcomers to it, so that more accountable organizations such as government departments and banks tend to avoid it, preferring more explicit descriptors such as "fraudulent" or "phishing. Email Spamming: Email spam, also known as junk email or unsolicited bulk email (UBE), is a subset of spam that involves nearly identical messages sent to numerous recipients by email.

Email Spamming

Email spam, also known as junk email or unsolicited bulk email (UBE), is a subset of spam that involves nearly identical messages sent to numerous recipients by email. Email spam has steadily grown since the early 1990s. Botnets, networks of virus-infected computers, are used to send about 80% of spam. Spammers collect email addresses from chatrooms, websites, customer lists, newsgroups, and viruses which harvest users' address books, and are sold to other spammers. They also use a practice known as "email appending" or "epending" in which they use known information about their target (such as a postal address) to search for the target's email address. Much of spam is sent to invalid email addresses. Spam averages 78% of allemail sent. According to the Message Anti-Abuse Working Group, the amount of spam email was between 88–92% of email messages sent in the first half of 2010

Email Bombing

An e-mail bomb is a form of net abuse consisting of sending huge volumes of e-mail to an address in an attempt to overflow the mailbox or overwhelm the server where the email address is hosted in a denial-of-service attack.

Email Threatening

Email is a useful tool for technology savvy criminals thanks to the relative anonymity offered by it. It becomes fairly easy for anyone with even a basic knowledge of computers to become a blackmailer by threatening someone via e-mail.

In a recent case, Sushmita received an e-mail message from someone who called him or herself 'your friend'. The attachment with the e-mail contained morphed pornographic photographs of Sushmita. The mail message said that if Sushmita were not to pay Rs. 1,00,000 at a specified place every month, the photographs would be uploaded to the Net and then a copy sent to her fiancé. Scared, Sushmita at first complied with the wishes of the blackmailer and paid the first Rs. 1,00,000. Next month, she knew she would have to approach her parents. Then, trusting the reasonableness of her fiancé she told him the truth. Together they approached the police. Investigation turned up the culprit - Sushmita's supposed friend who wanted that Sushmita and her fiancé should break up so that she would get her chance with him.
