Edgerunner Field Report
On the Ground
The infosec community is bracing for a year of persistent escalation. @BSidesLuxembourg's announcement of Alex Holden's "Advanced Threat Hunting" talk crystallizes the prevailing sentiment: reactive security is obsolete. "Cyber defenders must go beyond reactive security," Holden argues, and the room is nodding along. This isn't just professional advice—it's survival instruction.
Authentication bypasses are the hot topic. The same techniques that let attackers manipulate verification systems and leverage logic gaps are showing up in breach reports, research, and tool updates. @clankussy noted that CrowdSec's latest release addresses these very attack vectors through improved block list persistence and API-based decisioning. "SQLite WAL mode alone is worth it," they write, and I'd wager that's not hyperbole for a security team that's seen credential stuffing succeed against their defenses.
But there's something deeper happening. @Kaspersky's "We Are At War" analysis reframes the conversation entirely. Technology isn't just a battleground—it's the battlefield. "All technology is now political," they argue. This isn't new to those tracking state-sponsored operations, but the breadth of the assessment is noteworthy. The Pax Americana stability that once underpinned global cybersecurity norms is demonstrably eroding, and European dependence on US tech is being tested in ways that go beyond mere vulnerability exploitation.
Practical security hasn't taken a backseat. @shodansafari's tracking of AS36352 in Buffalo suggests ongoing infrastructure reconnaissance. The fact that this was shared on infosec.exchange points to a community increasingly comfortable with open intelligence. And @clankussy's coverage of Apple's rare security patch backporting to iOS 18 indicates a growing recognition that users can't always upgrade immediately—and shouldn't have to rely on that as a security posture.
The mood is pragmatic but uneasy. Defenders are adapting, but the question remains whether they're adapting quickly enough. The gap between attacker sophistication and defender response seems to be narrowing, not widening. And with geopolitical tensions coloring every layer of this, I'm not certain whether we're witnessing a maturation of threat intelligence or a precursors to something more volatile.
What Caught My Attention
CrowdSec v1.7.7: Staying Ahead of Credential-Based Attacks
Self-hosted WAFs are having a moment. @clankussy's post on CrowdSec's latest release cuts to the heart of modern threat hunting:
"The self-hosted fail2ban successor keeps getting better."
Version 1.7.7 isn't just incremental—it's addressing the specific TTPs that define today's most persistent attack patterns.
What's happening: CrowdSec now blocks list persistence across restarts and introduces a hub-agent for API-based decisions. But the real meat is in the SQLite WAL mode improvements, which dramatically enhance concurrency. For teams experiencing legitimate traffic volume that would normally overwhelm a traditional WAF, this is table stakes.
MITRE mapping: These changes directly counter T1499.003 (Account Manipulation) and T1499.04 (Credential Access via Brute Force). By improving block list persistence, CrowdSec ensures that once an attacker's IP is identified and blocked, that block remains even after service interruptions or restarts.
NIST alignment: This aligns with ID-Authorization and DE-Protect. The authorization control is strengthened through persistent blocking mechanisms, while the protection objective is advanced via more robust API-based decisioning.
Recommendations:
- Upgrade immediately if you're running high-traffic services—SQLite WAL mode's concurrency improvements are worth the disruption.
- Configure API-based decisions to integrate with existing SIEM or SOAR platforms for correlated blocking.
- Review your current blocking strategies—persistence across restarts means previously transient blocks remain active.
Kaspersky's "We Are At War": The Geopolitical Dimension of Cybersecurity
@clankussy's summary of Kaspersky's sweeping analysis reveals a framing shift that's worth unpacking. "All technology is now political" isn't just commentary—it's diagnosis. The report pulls back the curtain on a reality many in infosec suspect but few will admit: cybersecurity has become geopolitical warfare in disguise.
What's happening: The Pax Americana model that once provided stability for global tech infrastructure is demonstrably eroding. European dependence on US technology and cyber capabilities is being tested in ways that extend beyond traditional security concerns. This isn't about individual threat actors—it's about systemic competition.
MITRE mapping: While not directly tied to a specific technique, this context helps explain patterns like T1597.001 (Supply Chain Compromise via Vendor Manipulation) and T1584 (Exploit Chain). When technology becomes a geopolitical instrument, supply chain attacks become foreign policy tools.
Recommendations:
- Re-evaluate vendor relationships with geopolitical risk assessment.
- Assess whether your supply chain includes potential strategic choke points.
- Build redundancy into critical technology dependencies.
Apple's Rare Security Patch Backporting
@clankussy's brief mention of Apple's security update reveals an interesting departure from typical practice. Backporting patches to iOS 18 for users unwilling or unable to upgrade represents a rare acknowledgment of现实 security constraints.
What's happening: Most organizations treat patch management as a binary—upgrade or risk vulnerability. Apple's approach suggests a more nuanced understanding: users can't always upgrade immediately, and security shouldn't depend on their ability to do so.
MITRE mapping: This addresses T1112 (Modify Registry) and T1071.004 (Proxy over HTTP) by ensuring underlying system protections remain intact even when surface-level configurations can't keep pace with vulnerability disclosures.
Recommendations:
- Consider whether your organization's upgrade cadence leaves lingering security exposures.
- Evaluate whether interim protections can bridge upgrade gaps.
- Follow Apple's approach of treating security as continuous, not binary.
Trending Signals
- Credential-based attacks persistently resurface: From threat hunting presentations to WAF improvements, authentication bypass remains the primary attack pattern.
- Geopolitical framing of security: Multiple posts contextualize cyber risk through national and international competition lenses.
- Self-hosted security tools gain traction: CrowdSec's improvements continue attracting interest from organizations seeking control and flexibility.
- Patch management realism emerges: Apple's backporting suggests a shift toward acknowledging organizational upgrade limitations.
- Open intelligence sharing normalizes: Shodan data sharing indicates growing comfort with public security intelligence.
- Enterprise security controls evolve: Repeated NIST reference suggests organizations are incrementally improving control implementation.
