SoundCloud’s December 2025 breach has been added to HIBP, confirming exposure of ~29.8M user accounts.
The incident stemmed from unauthorized access to an internal service dashboard that enabled correlation of email addresses with public profile data. No credentials or financial information were compromised, but the case highlights how internal tooling can expand the attack surface.
What practical controls help reduce correlation risk in large platforms?

A technical disclosure this week detailed a conditional server-side authorization issue affecting Instagram’s mobile web interface.
Under specific backend states and header conditions, private media metadata and CDN links were reportedly returned without authentication.
The issue was patched silently, but the lack of formal root-cause acknowledgment has sparked discussion within the security community.
This case underscores how partial-impact vulnerabilities can be harder to detect - and potentially more concerning - than global failures.
How do you approach disclosure confidence when fixes arrive without explanation?

ExpressVPN’s winter pricing highlights a broader industry trend: aggressive discounts on multi-year VPN plans paired with security-first messaging.
From a technical standpoint, notable components include:
• Lightway protocol for fast session establishment
• AES-256 encryption
• TrustedServer (RAM-only, audited) architecture
• Private DNS and optional parental controls
• Identity monitoring features in specific regions
As always, pricing is only one variable - threat models, jurisdiction, and operational transparency remain key when assessing VPN services.
What do you personally prioritize most when assessing a commercial VPN?

SegurCaixa Adeslas disclosed a breach affecting personal identity and banking data of policyholders in Spain’s Extremadura region.
Health data and billing platforms were reportedly not accessed, and no fraud has been observed so far.
The incident reinforces the importance of secure data retention, breach containment, and clear post-incident communication to reduce secondary risks like phishing and impersonation.
How do you assess disclosure quality in incidents like this?

Ireland plans legislation to formally permit law enforcement use of spyware, with court authorization and stated safeguards.
The move reflects a wider trend of governments updating interception laws to match modern technology, while attempting to preserve oversight and proportionality.
How should security professionals evaluate such frameworks from a risk and governance perspective?

I’ve published a new piece with Sicla Media on zero-access architecture — a design approach that assumes breach and limits damage by removing provider access to message content altogether.
It’s often confused with “just encryption”, but the differences matter — technically, legally, and long-term.

Recent research into sleeper browser extensions across Chrome, Edge, and Firefox highlights a persistent issue: delayed-activation threats.
By embedding code inside images and activating only after updates, these extensions avoided early detection while maintaining prolonged access to browser data.
The findings reinforce the importance of continuous monitoring, extension inventory management, and permission reviews - especially for widely used consumer tools.

Thoughtful discussion welcome.

In HealthTech, “remove identifiers” isn’t a DataPrivacy strategy. k-anonymity can reduce singling out in shared tables; differential privacy helps when you publish aggregates or answer many queries.

The Victorian school data breach underscores how context matters in impact assessment. Even when highly sensitive fields remain untouched, exposure of identity-linked student data can carry downstream safety implications.
Education environments combine large datasets, third-party dependencies, and vulnerable populations - making incident response as much about communication and long-term monitoring as containment.
This case reinforces why breach severity can’t be judged solely by data categories.

Professional discussion encouraged.

Eurail B.V. has disclosed a data breach affecting personal and sensitive traveler information, with investigations still ongoing.
Potentially accessed data may include:
• Identity and contact details
• Passport or national ID records
• Limited financial or health-related data for specific EU program participants
The company reports that affected systems were secured, credentials reset, and customers advised to watch for phishing or identity-related abuse.
This incident underscores the risks associated with centralized identity and travel databases, especially in cross-border environments.

The FTC finalized a consent order limiting GM and OnStar’s ability to share geolocation and driving behavior data and requiring explicit consent, access rights, and opt-out controls.
While not a breach scenario, the case is relevant to InfoSec and privacy teams as it reflects:
- Regulatory expectations for telemetry and behavioral data
- Risks tied to secondary data use
- Growing scrutiny of embedded and IoT-style data collection
How should security and privacy teams approach data governance in connected systems?

Recent debate highlights how consumer platforms manage age-based transitions for supervised accounts.
Following public concern, Google stated it will require formal parental approval before teens can exit supervised account settings. While no security breach is involved, the issue intersects with privacy design, consent models, and child data governance.
From a governance perspective, this raises questions about:
• consent frameworks for minors
• notification design
• regulatory alignment across regions
How should platforms architect parental control systems to balance autonomy and protection?

wa-crypt-tools is an open-source toolkit for handling encrypted WhatsApp backups (.crypt12/.crypt14/.crypt15) when the legitimate key is available.
The project supports protobuf-based formats, integrates with forensic workflows, and is frequently cited in research on E2EE behavior, message retention, and backup security. It reinforces that encryption remains intact - access hinges on key control, not exploitation.
How do you see tools like this shaping future mobile forensic standards?
