Since April 2019, there is a new type of attacks that use emails as an attack vector: the so-called Email Reply Chain Attacks. The first step in these attacks is to spy on emails. The responses to these emails written by the criminals contain a malicious link or attachment. While this method was initially used on a larger scale by Emotet, other threats such as QakBot (aka Qbot or also Quackbot) have also been added over time.
For several years, spammers have increasingly used text-based HTML attachments to spread malicious code. A double-click in the browser is enough to execute malicious code that is either embedded in the HTML document or reloaded via external web servers.
Email encryption is the basis for data protection and legal security in your company. Encryption is no longer a marginal topic for organizations, and that’s a good thing: Rising threats from espionage and automated email screening by intelligence agencies show how important it is to protect your communications. In addition, encrypted communication with suppliers or external service providers is a prerequisite for awarding contracts in many industries. Until now, the email certificates required for encryption required administrative effort to acquire, distribute and manage. With Managed Certificates, you automate certificate management and reduce the effort to a minimum.
Currently, criminals are trying to install malware via text-based CSV files. We show how you can protect yourself from CSV injection attacks.
The December update of NoSpamProxy Cloud has made available two functions, Encryption and Managed Certificates, which significantly simplify the encryption of emails and the management of the required certificates. To be more precise, it couldn’t be easier: With Managed Certificates you can create certificates automatically and renew them before they expire, without any effort on the part of customers or service providers.
As of April 1, 2022, the requirements for email certificates will be tightened. SwissSign will stop issuing e-mail certificates with a 3-year term in March 2022. Only e-mail certificates with a validity of one or two years will then be available. Certificates with a validity of 3 years issued before April 1 will remain valid after the cut-off date and will not be revoked.
ADN quickly decided on NoSpamProxy Encryption, which was functionally convincing and also promised the best possible support for data protection requirements in the German-speaking region as well as excellent support.
