Does anti-spam still work after 20 years of spam emails?

It’s a depressingly normal sight for anyone with an email account. You check your inbox to find emails that offer you knock-off prescriptions, sexual enhancement drugs and huge cash prizes in exchange for sensitive financial information.

Then there are also phishing emails, which contain links to fake login pages to trick the user into giving away login details to online banking accounts, or that lead to a malicious website that installs malware on a user’s computer.

CaptureThey are usually sent out from groups of infected computers, called botnets, with the aim of reaching as many email accounts as possible. They can not only affect an individual computer but can compromise all the systems in an organization, which can cause devastating results.

Spammers also use botnets to help rig online competitions or to gather more email addresses for sending spam to.

Here is some advice that can help protect you against spam.

  • Configure your company’s systems correctly – Many companies set up a web server but don’t end up configuring it properly. Professionals suggest that you disable unnecessary components in your system to reduce many vulnerabilities.
  • Make sure your employees  know about spam – If employees are trained to know what to look out for, it puts your organization in good stead for any future difficulties. One good method is to send fake emails to all employees and give out rewards for the ones who spot the ones that are not legitimate.
  • Control how administrators access data – reduce access to only Capturethose that ‘need to know’ so they can’t be bypassed  Tools like encryption combined with separated access controls can be used to remove administrators from data access. Administrators are often major targets from spammers due to the amount of systems they have control over.
  • Isolate accounts that could be a target for attack – User accounts which have access to sensitive company data need additional security measures applied to them, as they are prime targets for malware-driven hacking attempts, which often start from an employee clicking on a malicious email.
  • Patch known security vulnerabilities – Your organization will know that they need anti-virus measures but other aspects are often forgotten. Only 4.7% of all vulnerabilities are used to break into organizations which could have been stopped if the vulnerabilities had been patched in the first place.

All sounds like a lot of hard work, doesn’t it? With this in mind, we’ve decided to make things easier by creating a unique anti-spam software solution that can protect you against global spamming trends.

CaptureExclaimer Anti-spam is built to recognize spam in a uniquely advanced way, algorithmically identifying unusual volumes of similar messages being sent from multiple sources – key indicators of spam and botnets.

The software uses the Recurrent Pattern Detection® engine from Commtouch®, which is constantly monitoring email traffic worldwide and detecting global spam trends. Users only need to use one console to control everything, so we let you adjust Microsoft Exchange’s built-in anti-spam functionality through our interface. By analysing the context, not the content, it works in any language, even on images, and won’t block a vital email just because it doesn’t have a subject line.
