Scamming is no longer a fringe phenomenon. Behind the innocent-sounding term lies a multitude of sophisticated scams that are used on a massive scale, particularly via email. Whether phishing, CxO fraud or romance scams, in this article you will learn how modern scams work, how to recognise them and what measures you can take to effectively protect yourself and your company.
On March 15, 2025, the licence for the Core Antispam Engine expired for some customers. In some cases, this resulted in temporary rejections of emails.
E-invoicing will be mandatory from January 1, 2025 and many companies already use a dedicated email address to receive e-invoices. Find out why this makes sense and how NoSpamProxy optimally protects your mailbox in this blog article.
The spam filter project Nixspam is ceasing operations. Since January 16, 2025, the DNS blacklist (DNSBL) no longer contains any entries under the domain name ix.dnsbl.manitu.net.
The protection of personal and business data is becoming increasingly important. Whether private chats or the exchange of sensitive documents, ensuring the confidentiality and integrity of transmitted information is crucial. End-to-end encryption (E2EE) ensures that data is only accessible to the intended recipients and is protected against attacks and manipulation. However, gateway-to-gateway encryption (G2GE) also offers secure protection. Find out exactly what the differences are and which approach makes sense for you in our blog post.
Cyber criminals are currently using phishing to spread a malware called Strela Stealer via German-language emails. Strela Stealer harvests login data from Outlook and Thunderbird accounts. The criminals then use originally legitimate emails containing invoices, which they forward and send to their victims. These victims then receive what appear at first glance to be identical emails, with only the recipient address and the attachment having been changed. Instead of the invoice, the criminals send .zip files with the same name that contain malware. Our data based on the meta information collected in 32Guards shows the approach of the spammers as well as the distinctive features of phishing emails – and how you can protect your email address from misuse.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) plays a central role in protecting email domains against misuse. However, the correct configuration of a DMARC policy is crucial: a seemingly harmless setting such as ‘p=none’ can lead to considerable security risks.
