Advanced email hacker attacks are on the rise

Current threat: Emotet

Emotet - the most dangerous malware out there

Emotet is an advanced Trojan that changes almost every day. It is often described as "the most dangerous malware out there" and something that the shipping industry is increasingly encountering in targeted attacks. Sophisticated email security is essential in effectively combating this ever-evolving threat.

Global spam amount 50.18 %

Global spam amount 2020 according to consultants Kaspersky: 50.18 per cent

More than half of all email messages are fake. Let us help you reduce the number reaching onboard inboxes to minimise distractions and inadvertent execution of potentially harmful content.

Attacks by email: 9 out of 10

9 out of 10 attacks starts with an email

More than 90% of all hacker attacks begin via email. Preventing these malicious and potentially harmful messages from reaching end-users is essential.

File size between 10 to 50 KB: 26.84 %

File size in spam emails has grown

Spam email size has grown in recent years. The share of emails sized 20–50 KB rose to 28.20% of the total number of registered spam emails in Q3 2020. On satellite networks, the sheer data volume of spam translates to unnecessary bandwidth consumption and, therefore, might represent a substantial cost.

My life has become easier

Holger Börcher and Briese Schiffahrt based in Leer, Germany, chose Dualog® Business Mail for their fleet of 130 ships. After the initial planning and testing phase was finalised, the entire transition period took less than nine months. When asked about why he chose Dualog, he explains: "We had to replace numerous outdated systems with one reliable and future proof solution across the entire fleet. I needed one unified strategy to deal with data management and cybersecurity. I found that Dualog had a unique offering, and I can now focus on business improvements instead of problems."
