Zero-day exploits are among the most dangerous threats in IT security. They exploit previously unknown vulnerabilities in software for which no protective measures yet exist, which makes them particularly insidious. This type of attack is often used by hackers, but also by secret services, to compromise systems undetected. In this article, you will learn how zero-day exploits work, what forms they can take and how you can best protect yourself against them.

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.

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.
