Today, we’ve got one more…

I recently had the opportunity to sit down with two of F5’s top threat researchers, Sara Boddy and Justin Shattuck, to pick their brains about IoT, its current state of “security,” and what we can expect to see in terms of threats, attacks, and mitigations in the future. Justin and Sara are co-authors of three IoT threat research…

This isn’t your mama’s botnet. This is a proper botnet. If you were the world’s best IoT botnet builder and you wanted to show the world how well-crafted an IoT botnet could be, Reaper is what you’d build. It hasn’t been seen attacking anyone yet, and that is part of its charm. But, what is…

So, what’s the issue when it comes to encryption and quantum computing? Today’s asymmetric encryption algorithms, which are primarily used for key exchanges and digital signatures, are considered vulnerable to quantum computers. For example, using today’s traditional, digital, transistor-based computers, it’s estimated it would take 6 quadrillion CPU years to crack a 2048-bit RSA decryption key.7 But,…

  We also analyzed the primary root causes of the breaches, how that varied in breach remediation costs by industry, and the impact of these breaches on each data type breached on the global scale. The purpose of our analysis was to identify where organizations are most likely to be attacked in a way that…

F5 threat researchers have discovered a new Apache Struts campaign. This new campaign is a sophisticated multi-staged attack targeting internal networks with the NSA-attributed EternalBlue and EternalSynergy exploits. We have dubbed the campaign “Zealot” based on the name of the zip file containing the python scripts with the NSA-attributed exploits. As we continue to research…
