Regardless of the proliferation of text and social media, email communication is still growing strong. According to recent study by the Radicati Group, the total volume of worldwide emails sent and received reached 205 billion per day, with this volume projected to increase by at least 5% every year.

Email Threats Organisations Face Today
- Malware – email is one of the top delivery mechanisms to distribute known & unknown malware, which are typically embedded into email attachments in hopes that the attachment will be opened or downloaded onto a computer or network, thereby allowing hackers to gain access to resources, steal data, or crash the entire system.
- Ransomware – One particularly nefarious malware variant is ransomware. Once the email attachment is activated, the code embeds itself on a network and ransomware typically encrypts or locks critical files and systems. The hackers then coerce the
organisationto pay an extortion fee in order to have the files or systems un-encrypted or unlocked.
- Phishing – this common hacker tactic
utilisesemails with embedded links to hacker sites. When gullible users visit these sites, they’re prompted to enter PII (Personable Identifiable Information) that is in turn used to steal identities, compromise corporate data, or access other critical systems.

- Business Email Compromise / CEO Fraud / Impostor email – Over the past two years, Business Email Compromise (BEC) schemes have caused at least $3.1 billion in total losses to approximately 22,000 enterprises around the world, according to the latest figures from the FBI. The FBI defines Business EMail Compromise as a sophisticated email scam that targets businesses working with foreign partners that regularly perform wire transfer payments.

- Outbound Email Hijacking – Corporations are also subject to corporate policies and government regulations, which hold businesses accountable for their outgoing emails and ensuring they protect their customer’s PII. Zombie attacks and IP hi-jacking can disseminate customer PII, ruining the reputation of a business.
