End-to-End Encryption or Gateway-to-Gateway Encryption?

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.

Phishing with fake invoices: Hijacked mail logins are used for new phishing attacks

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 Policy: Why p=none is a bad choice

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. In this article, we explain why ‘p=none’ is a bad choice and what an effective DMARC record should look like.
