SoundCloud Breach Hits 30 Million Users While Quantum Computing Reshapes Our Security Playbook

We’ve got quite a mix of security news this week that really highlights where our industry is heading – and some familiar headaches we’re still dealing with. Let me walk you through what caught my attention and why it matters for those of us in the trenches.

Another Day, Another Massive Breach

The big story that’s probably hitting your inbox right now is the SoundCloud data breach affecting 29.8 million accounts. If you’re keeping score at home, that’s roughly 30 million users who just had their personal and contact information compromised.

What strikes me about this breach isn’t necessarily its size – we’ve unfortunately become numb to these massive numbers. It’s the reminder that even platforms we might not immediately think of as high-value targets are sitting on treasure troves of user data. SoundCloud isn’t a bank or a healthcare provider, but hackers still found it worth their time to go after nearly 30 million records.

This reinforces something I’ve been telling clients for years: if you’re collecting user data, you’re a target. Period. The attackers aren’t just going after the obvious targets anymore – they’re casting wider nets and finding success with platforms that might have assumed they were flying under the radar.

The Quantum Computing Reality Check

Speaking of things that should be on our radar, there’s an interesting piece about quantum computing and its potential synergy with advanced AI that’s worth our attention. I know, I know – quantum computing has been “just around the corner” for years now. But here’s the thing: it’s not theoretical anymore.

We’re looking at computing power that could fundamentally break the cryptographic foundations we’ve built our entire security infrastructure on. And when you combine that with the AI advances we’re seeing, we’re talking about a potential paradigm shift that makes our current threat models look quaint.

The reality is that most organizations aren’t prepared for post-quantum cryptography. We’re still dealing with basic hygiene issues like patch management and password policies, and now we need to start thinking about cryptographic agility. It’s not panic time yet, but it’s definitely planning time.

Privacy Rights Meet Law Enforcement Tech

On the policy front, there’s a fascinating development with the Supreme Court considering the constitutionality of geofence warrants. The case involves a Virginia robbery where police used Google location data to identify suspects in a specific geographic area.

This hits close to home for those of us who work with location data or mobile security. The technical capabilities exist to do this kind of broad surveillance, but the legal framework is still catching up. Depending on how the Court rules, we might see significant changes in how law enforcement can access location data – and by extension, how we need to handle and protect that data.

The case shows how our technical capabilities are outpacing our legal and ethical frameworks. As security professionals, we’re often the ones implementing these systems, so understanding the privacy implications isn’t just good practice – it’s becoming a professional responsibility.

Moving Beyond Vulnerability Whack-a-Mole

There’s also some good thinking happening around Continuous Threat Exposure Management (CTEM), which addresses something I’ve been wrestling with in my own work. We’ve gotten really good at finding vulnerabilities and identifying threats, but we’re still struggling with the “so what?” question.

CTEM tries to answer that by looking at where threats and vulnerabilities actually intersect in your specific environment. Instead of treating every CVE like a five-alarm fire, it helps you figure out which exposures actually matter in your context. Can an attacker realistically exploit this? Do we have effective defenses in place? Are we spending time on the right problems?

This resonates with me because I’ve seen too many teams burn out trying to patch everything or respond to every threat intelligence report. The smart money is on building systems that help you prioritize based on actual risk in your environment, not just theoretical possibilities.

Looking Ahead

Oh, and if you’re planning conference travel, RSAC 2026 registration is apparently open. I know it feels early, but if the past few years have taught us anything, it’s that the good sessions fill up fast.

What ties all of this together for me is that we’re at an inflection point. The threats are getting more sophisticated (quantum + AI), the legal landscape is shifting (geofence warrants), and we’re finally starting to mature our approach to risk management (CTEM). Meanwhile, we’re still dealing with the same fundamental problems – massive data breaches that could have been prevented with better security practices.

The key is staying focused on the fundamentals while preparing for what’s coming next. We can’t solve tomorrow’s quantum computing challenges if we haven’t figured out today’s basic security hygiene.
