First, we've just launched a new revision of the portal that includes a self-service OAUTH sign-up. Your now "legacy" API keys will still work in any scripts which talk to the API directly, but if you're interfacing through the UI, you'll need to re-register. Do let us know if there are any issues, and all feedback is welcome. We are already hard at work on the next revision, which focuses on expanded search capabilities, improved performance, and access to all file types within our corpus, as opposed to just Office documents. Stay tuned.

Second, we've launched a dedicated section for an ongoing research project we call "The Trystero Project." In a nutshell, we're leveraging our daily harvest of malware (not just the Office documents) to compare the efficacy rates of Google vs. Microsoft regarding email security. It's a neat experiment, and the trophy goes back and forth between the two. Please take a look at our live dashboards, read more from the linked blogs, listen in on the podcast, or watch our CTO Pedram Amini's presentation on the experiment. One interesting freebie atop of this experiment is extending this assessment to any corporate domain.

Espionage Utilizing Mobile Devices

Posted on 2021-07-30 by Dmitry Melikov

Pegasus is an advanced cyber-espionage tool that includes plenty of functionality that allows you to spy on mobile users. Cybersecurity researchers are not aware of many of the vectors that the team uses to identify victims. One of them is sending the user a malicious link that exploits a specific vulnerability to install the implant. It is not a problem for them to know the victim's location using the GPS locator function. The attackers get access to the phonebook and also to the files stored on the victim's device. They can read SMS messages and view the call history.
