Email Rules as a Point of Entry: How Attackers Take Control of Microsoft 365 After Compromising an Account

32Guards, All Topics, News, NoSpamProxy Cloud, NoSpamProxy Protection

Email rules are actually designed to organize your inbox: automatically moving, forwarding, or marking messages as read. It is precisely these functions that make them attractive to attackers once an account has been compromised. In many cases, at least one malicious email rule is created shortly after the initial access, sometimes within seconds of the unauthorized login. We’ll show you how these attacks work and how you can protect yourself.

Seasonal threat: Cybercriminals don’t take vacations

25Reports, 32Guards, All Topics, News, NoSpamProxy Cloud, NoSpamProxy Encryption, NoSpamProxy Protection

Summer is here, out-of-office replies are enabled, and besides those looking forward to vacation, there’s one group that’s especially happy: cybercriminals.

DKIM richtig betreiben: Der Schlüssel zu sicherer E-Mail-Kommunikation 800x800

Getting DKIM Right: The Key to Secure Email Communication

25Reports, All Topics, News, NoSpamProxy Cloud, NoSpamProxy Protection

Emails end up in the customer’s spam folder or get rejected, but why? DKIM is configured, SPF is set up, and DMARC is running. Everything was green in the last check, six months ago. After all, DKIM is supposed to ensure that emails are cryptographically signed and that neither the sender nor the content can be tampered with. This scenario is not an isolated case, but rather the result of treating DKIM as a one-time task rather than an ongoing one. In this blog post, you’ll learn what’s important when using DKIM and what common mistakes you should avoid when setting up and maintaining DKIM.

You are responsible for the security and satisfaction of your customers and for the quality of your recommendations. That is exactly why it’s worth taking a closer look at NoSpamProxy.
