The CAN-SPAM Act of 2003 became law on January 1, 2004. According to the FTC, if you violate the law, you could be fined $11,000 for each offense—that’s $11,000 for each email address on your list. ISPs around the country have already successfully sued spammers for millions of dollars under this law. If you send commercial email (generally sales or promotional content), you should familiarize yourself with the requirements of CAN-SPAM. Canada’s Anti-Spam Legislation (CASL) went into effect on July 1, 2014 and carries penalties of $1-10M per violation.

What is spam filtering?

Spam filters detect unsolicited, unwanted, and virus-infected emails (called spam) and prevent it from reaching email inboxes. Internet Service Providers (ISPs) use spam filters to ensure that they do not distribute spam. Small and medium-sized businesses (SMBs) also use spam filters to protect their employees and networks.

Spam filters apply to both incoming email (that which enters the network) and outgoing email (that which leaves the network). ISPs use both methods to protect their customers. SMBs tend to focus on inbound filters.

Concretely, anti-spam consists of the following elements:

a Real-time Blackhole List or RBL ( black lists of IP addresses and emails),
a heuristic analysis engine,
white lists,
a Bayesian method (deduction of the probability that the email is spam),
spam databases,
a URL verification algorithm,
a DNS configuration,
an SPF configuration,
a transaction history,
preferences of the user and the user company.

However, be careful with too strict anti-spam, because they generate false positives (legitimate emails redirected to the spam folder).

There are many spam filtering solutions available. They can be hosted in the “cloud”, on computer servers or integrated into email programs such as Microsoft Outlook.

How do spam filters work?

Spam filters use “heuristic” methods, which means that each email message is subjected to thousands of predefined rules (algorithms). Each rule assigns a numerical score to the probability that the message is spam. If the score exceeds a certain threshold, the email is marked as spam and blocked from continuing.

There are different types of spam filters for different criteria:

Content Filters – Analyze the content of messages, looking for words that are commonly used in spam emails.
Header Filters – Examine the origin of the email header for suspicious information (such as spam email addresses).
Block List Filters – Stops emails that come from a suspicious IP address block list. Some filters go further and check the reputation of the IP address.
Rule-based filters – Apply custom rules designed by your organization to exclude emails from specific senders, or emails that contain specific words in their subject line or body.

You can also run your message through certain tools, such as Mail Tester to check an email for “spam”.

Neither method is a complete solution to the spam problem, and there are always trade-offs (which heuristics try to balance) between rejecting legitimate emails and letting spam slip through.

Why You Need an Effective Spam Filter?

Independent tester recognized that businesses typically use more functional professional email services than mainstream email services, but a similar test on popular internet security products also showed extremely low spam detection rates.

To name just a few known examples featured in the test: Avast (96.71%), and Symantec (93.63%). With lower scores, there are Outlook and McAfee in particular.

This shows that not only do businesses need an additional anti-spam solution, but an effective solution should be chosen. Even the most powerful anti-spam mechanism mentioned above (Avast) allowed over 4000 spam emails to pass through its filters undetected in the test.

In today’s world, spam filtering is a must to protect your business. Spam is not going away.

An estimated 70 percent of all emails sent worldwide is spam, and the volume continues to grow because spam remains a lucrative business. Spammers are getting more sophisticated and creative in their tactics to push your messages into inboxes and wreak havoc. Spam filtering solutions must be continually updated to address this evolving threat.

A spam filtering solution cannot be 100% effective. However, a business email system without a spam filter is highly vulnerable, if not unusable. It is important to stop as much spam as you can, to protect your network from the many possible risks: viruses, phishing attacks, compromised web links, and other malicious content.

Spam filters also protect your servers from the overload of non-essential emails, and the worst problem of being infected with spam software that can turn them into spam servers themselves.

By preventing spam from reaching your employees’ mailboxes, spam filters offer an additional layer of protection for your users, your network, and your business.

The most important risks, however, are intrusion attempts in order to commit damage (data theft, destruction of data, theft of money, identity theft, etc.).

Pop-up Commercial Advertisements

Spurious commercial emails are emails perceived as unnecessary and sent to lists of recipients who have not explicitly given their consent (opt-in) to receive these emails.

This can happen if the listings have been bought or stolen. It is sometimes impossible to permanently unsubscribe from these lists (opt-out), which poses a real problem in terms of compliance with the GDPR.

Most of the time, these are scams or paid online services (adult sites, home loans, training, online games, premium-rate numbers, etc.).

Website Hacking via FTP – Infected with Malware

It is a precautionary measure to prevent the infection that the website has from spreading to the PCs or browsers of those who visit the web. Else, without knowing they will automatically download a virus on their computer.

Contrary to common sense (“if my site has a virus, my hosting provider’s web server is infected”), the problem is almost always on the PC from which the website is updated.

This is a very common way to add virus or malicious code to a site by tricking the user into opening spam emails. The user unintentionally opens the attachment and uploads the malicious file to their website through the FTP manager.

Spam email can damage programs, delete files, and reformat or erase your hard drive, resulting in reduced performance or even a complete crash of your system. Hackers can also use such viruses to access your personal information in order to steal or destroy your website data if you upload files from an infected PC to your website. Ref- [WordPress Hacked]

Those who are dedicated to sharing this type of virus through Spam emails, with the intention of spreading them through the internet, aim to steal fundamental information: your FTP keys.

With these keys, they upload infected files or their modified pages, without you noticing. If the attack is sufficiently elaborate, they will even instantly get your new FTP password the moment you change it.

Phishing

Phishing is an email fraud technique that involves pretending to be a trusted third party (bank, insurance, social security, etc.)program to extract personal information or money. Phishing emails usually look like very close copies of the official website.

A variation of phishing, spear phishing, consists of personalizing messages sent to a small number of users (versus a generic email sent to a maximum of potential victims).

It is estimated that 91% of hacking attacks start with a phishing email, hence the importance of it is important to set up effective filtering of these unwanted emails.

Ransomware

Ransomware is a virus that infects a workstation. It will encrypt all or part of the files on the computer or even on the computer network.

The victim must acquire a decryption key that the hacker (pirate) gives him in return for a ransom. Ransomware can lead to a business shutdown… or worse.

In February 2016, for example, the Los Angeles hospital was hit by ransomware received by email. Medical records were inaccessible for hours endangering human lives. In 2016, ransomware revenue amounted to $ 1 billion in the United States alone (source: FBI)
