Email security threats

Every organization has data that they can’t function without. Hackers exploit this need by blocking access or stealing files in order to extort payment.

Threat actors are now not only demanding money; they’re also removing sensitive data from the systems they attack, and the cost of damage to operations, assets and corporate reputation can easily run into millions.

Phishing is often the hackers’ first choice in getting ransomware through, tricking victims into directly releasing account logins or clicking a malware-laced link. Once they’re in, the malicious activity begins.

Account takeover can cause all kinds of havoc and reputational damage.

Cybercriminals use bots or phishing to take over legitimate email accounts and use them to steal funds or data, install malware or ransomware.

They can also use stolen email accounts to make phishing attacks on others, so that recipients more likely to trust the sender and to do what they ask.

Hackers can change anything related to the account they’ve taken over, such as security questions, passwords and encryption settings.

This makes it impossible for the real owner to gain access.

With only a little coding knowledge, cyber criminals can send phishing emails from what appears to be your domain name (spoofing). Because these emails look to be from a trusted source, they can easily pass unnoticed.

By sending requests for payment, links, or even fake security questions, bad actors can then steal funds or data, or infiltrate third parties with malware or ransomware – all in your name.

To block unauthorized use of your brand and maintain trust in your domains, it’s essential to set up the right email authentication protocols (DMARC, DKIM and SPF).

You’ll be protecting your legitimate email addresses, as well as meeting the email security requirements that Google, Microsoft, Yahoo! and others demand of high-volume senders. And you don’t need specialist knowledge to put these simple measures in place.

Phishing contributes to 82% of all data breaches. Hackers exploit human nature as the weakest link in any cybersecurity strategy, sending fake emails to trick employees into giving away vital information.

It used to be relatively easy to spot fake phishing emails, but easy access to AI tools has made attacks more sophisticated, and therefore far more plausible.

An attacker only needs to trick one person into revealing their login details to be able to cause all kinds of harm, such as the installation of ransomware, system sabotage, or data theft. The cost can run into millions.

Like any other security or safety measures, phishing awareness, avoidance and best practice need to be embedded throughout your organization.
