Spam spam filtering software

Two software engineers compiled a list of IP addresses that were sending the messages and created a blacklist which was made available to subscribers of the Mail Abuse Prevention System.

While initially developed to deal with nuisance emails, spam filters now have to block far more sinister threats and in much more significant volumes. The same blacklist system is still in use today. It contains the IP addresses of known spammers and is constantly updated. The blacklist is one of the key mechanisms for identifying spam emails and is at the heart of modern spam filters.

Spammers are constantly changing tactics to bypass RBLs and ensure their emails reach inboxes. Domains are used for very short periods before being abandoned, or thousands of domains are used to send small batches of emails at levels where spamming is unlikely to be detected. Blacklists are still important for blocking nuisance emails, but alone they will do little to block more sophisticated threat actors and more sinister threats.

Email is the malware delivery vehicle of choice for cybercriminals and the main way hackers gain access to healthcare networks. Phishing attacks on healthcare organizations are increasing and barely a day goes by without another report of a healthcare phishing attack. Each year, scores of businesses are fooled into disclosing W-2 Form data and making fraudulent wire transfers.

With appropriate technical solutions, policies, procedures, and staff training, it is possible to mount a robust defense against phishing attacks.

Without effective spam filtering software in place, healthcare organizations will not be able to manage and reduce threats to an acceptable level and data breaches and regulatory fines are likely to follow.

The use of blacklists is a common feature of spam filtering software, but in order to protect against more sophisticated attacks, additional mechanisms must be employed. Modern spam filters use an array of additional mechanisms to detect malicious messages and sophisticated phishing attacks.

DMARC is used to authenticate authorized users of a domain and detect email spoofing and brand impersonation attacks. In order to filter email spam The greylisting process returns every incoming email to the server from which it was sent, asking for it to be resent.

By using the greylisting process, spam filter software blocks spam emails from previously unknown sources of spam as well as previously reported sources of spam. Admittedly the process can delay the delivery of business-critical emails by up to five minutes while the spam email software is waiting for greylisted emails to be returned, but there are ways trusted accounts can bypass this process.

What few vendors of spam filter software tell you is it can be equally as important to filter your outbound mail as it is to filter your inbound mail. The reason for this is that, if your IP address is identified as a source of spam, it can be blacklisted — not only affecting communications into and out of your business, but also potentially affecting public access to your website.

Think again. One of the main goals of a phishing email is to obtain login credentials. The consequences could be more devastating to your business than if you were to suffer a malware attack yourself. In addition to likely being blacklisted, your reputation would be damaged. Scenarios such as these can happen inadvertently as well as maliciously.

Outbound filtering and scanning with antivirus software prevents these scenarios from occurring. The solution is also resistant to going down.
