Russia Launches a “Smart Postman” to Open Email Attachments Safely
Users can now upload an email attachment to a dedicated platform to check whether it contains malicious software.

When a suspicious attachment arrives in a work inbox, opening it can be risky, while waiting for an information security specialist to analyze it can sometimes take too long. A new web service called MalwaDet is designed to address this gap. It has been launched by the Russian cybersecurity and threat analysis company Solar (Solar 4RAYS).
Threat Indicators
The service is built around a simple and practical idea. A user selects a model that matches the file type and uploads the file to the platform. Within seconds, the service provides a security assessment. MalwaDet checks whether the object shows signs of malware, viruses, trojans, spyware or other threats before the file is opened.
Following Industry Best Practices
Modern malware detection relies on several approaches, ranging from code and behavior analysis to the use of machine-learning models to identify new or modified threats. These technologies make it possible to detect not only known threats based on signatures but also previously unseen samples that may be hidden in email attachments or files downloaded from the internet. Machine-learning models are widely used across the industry precisely because they improve the speed and accuracy of analysis without requiring manual expert review.
Machine Learning at the Core
At the heart of MalwaDet are machine-learning algorithms trained on large datasets containing both benign and malicious files. The platform evaluates an uploaded file across multiple parameters, including structure, metadata and behavioral patterns, and then draws a conclusion about its safety. This approach significantly speeds up initial analysis and helps reduce the workload on security teams, especially in situations where rapid decisions are required.
Threats Are Growing — AI Is Learning
The creation of MalwaDet reflects current cybersecurity challenges: the number of threats continues to rise, and performing detailed manual analysis on every suspicious object is no longer practical. Automated assessment tools have become an industry standard, helping reduce the risk of corporate system infections and data leaks. The new platform allows business teams to act proactively, checking files immediately after they are received instead of waiting for incidents to occur.
