The New Threat Intelligence Landscape: Collaboration, Necessity, and Evolving Dangers

A weekly roundup of the most significant cybersecurity threat intelligence developments from May 27 to June 3, 2025

In the shadowy corners of the digital world, threat actors never sleep—and neither do the cybersecurity professionals tasked with tracking them. This past week has witnessed several significant developments in the threat intelligence landscape, from unprecedented industry collaboration to stark warnings about the necessity of robust intelligence capabilities. As cyber threats continue to evolve in sophistication, the tools and approaches to combat them are similarly transforming.

The cybersecurity community has long struggled with a fundamental challenge: how to create a common language for discussing threat actors across different organizations and platforms. This week, that challenge saw a potential breakthrough. Meanwhile, retail organizations in the United States are facing a new wave of targeted attacks from sophisticated threat actors who have already wreaked havoc across the Atlantic. And amidst it all, industry leaders are sounding the alarm that threat intelligence has moved from a luxury to a necessity in today's digital landscape.

Let's dive into the most significant threat intelligence developments of the past week and explore what they mean for organizations and security professionals worldwide.

Microsoft and CrowdStrike Unite to Solve Attribution Confusion

In a landmark collaboration announced on June 3, 2025, Microsoft and CrowdStrike have joined forces to address one of the most persistent challenges in cybersecurity: the inconsistent naming and tracking of threat actors. The two industry giants have launched a Shared Threat Actor Glossary designed to eliminate the confusion that has long plagued attribution efforts.

For years, the cybersecurity industry has struggled with a Tower of Babel problem. The same malicious group might be tracked as "Fancy Bear" by one company, "APT28" by another, and "Strontium" by a third. This fragmentation has created significant obstacles for security teams trying to correlate threat intelligence from multiple sources.

The new glossary represents the first major attempt to standardize threat actor nomenclature across different security vendors. By creating a unified reference system, Microsoft and CrowdStrike aim to enhance the industry's collective ability to track, analyze, and respond to sophisticated threat actors.

"This collaboration marks a turning point in how we approach threat intelligence sharing," said a senior threat researcher involved in the project. "When everyone speaks the same language, we can respond more effectively to emerging threats."

The glossary is expected to cover major state-sponsored actors as well as financially motivated cybercriminal groups, providing standardized profiles that include typical tactics, techniques, and procedures (TTPs), target preferences, and historical campaign information.

For security professionals, this development promises to streamline threat intelligence consumption and analysis. Rather than spending valuable time cross-referencing different naming conventions, analysts can focus on the more critical task of understanding and mitigating threats.

Retail Under Siege: UK Attackers Set Sights on US Targets

In a concerning development for the retail sector, sophisticated threat actors responsible for a series of high-profile attacks against British retailers have now turned their attention to targets in the United States. According to researchers from Google's Threat Intelligence Group and Mandiant, the same cybercriminals linked to recent attacks on UK companies Harrods, Co-op, and M&S are now actively targeting US retail organizations.

The threat group, tracked as UNC3944 or "Scattered Spider," has demonstrated a pattern of focusing intensively on specific sectors before moving on to new targets. Their current focus on retail represents a significant threat to the industry on both sides of the Atlantic.

"The actor, which has reportedly targeted retail in the UK following a long hiatus, has a history of focusing their efforts on a single sector at a time, and we anticipate they will continue to target the sector in the near term. US retailers should take note," warned John Hultquist, chief analyst of Google's Threat Intelligence Group.

What makes these attacks particularly dangerous is the group's sophisticated social engineering techniques. Rather than relying solely on technical exploits, Scattered Spider has perfected the art of manipulating employees into providing access credentials or other sensitive information. This human-centric approach often bypasses even robust technical security measures.

The Retail & Hospitality ISAC, a threat information sharing group, has acknowledged awareness of these threats but has provided limited additional details. This situation highlights the critical importance of cross-sector threat intelligence sharing, particularly when dealing with threat actors who systematically target specific industries.

For US retailers, the warning is clear: prepare now for potential attacks. This preparation should include enhanced employee training on social engineering tactics, implementation of multi-factor authentication, and increased vigilance for unusual access patterns or account activities.

Threat Intelligence: No Longer Optional in Today's Threat Landscape

In a stark assessment of the current cybersecurity landscape, the CEO of Group-IB has declared that threat intelligence is no longer an optional component of security strategies. This pronouncement, made on June 3, 2025, reflects the rapidly evolving nature of cyber threats and the increasing sophistication of threat actors.

"Organizations can no longer afford to operate without comprehensive threat intelligence capabilities," the Group-IB CEO emphasized. "The threat landscape has become too complex, too dynamic, and too dangerous to navigate blindly."

This assessment comes at a time when various threat actors are demonstrating increasingly sophisticated tactics. Just this past week, cybersecurity researchers have documented several advanced attack methodologies:

A novel attack exploited machine learning models on PyPI, using zipped Pickle files to deliver infostealer malware. This represents a concerning evolution in supply chain attacks, targeting the tools and libraries that developers rely on.

Europol led an operation that dismantled infrastructure for key initial access malware used to launch ransomware attacks. This success highlights the importance of international cooperation in threat intelligence and response.

A stealthy fileless PowerShell attack using Remcos RAT bypassed antivirus by operating entirely in memory. These "living off the land" techniques continue to challenge traditional security approaches.

Cyber espionage campaigns linked to North Korean actors have targeted Ukrainian government entities, demonstrating the continued blending of geopolitical tensions with cyber operations.

These diverse threats underscore the Group-IB CEO's assessment. Without robust threat intelligence capabilities, organizations lack the visibility needed to understand the specific threats targeting their industry, region, or technology stack.

The shift from viewing threat intelligence as a luxury to considering it a necessity represents a maturation of the cybersecurity industry. As threats become more targeted and sophisticated, generic security approaches are increasingly insufficient. Organizations need the contextual awareness that only threat intelligence can provide to effectively allocate their security resources.

The Evolving Threat Intelligence Landscape: Analysis and Implications

The developments of the past week reveal several important trends in the threat intelligence landscape. First, we're seeing unprecedented levels of collaboration between major security vendors. The Microsoft-CrowdStrike glossary initiative demonstrates a recognition that the industry must move beyond competition to address fundamental challenges collectively.

Second, threat actors continue to demonstrate remarkable adaptability. The shift of Scattered Spider from UK to US retail targets shows how these groups systematically explore and exploit vulnerabilities across geographic boundaries. This cross-border movement of threat methodologies requires equally fluid threat intelligence sharing.

Third, the technical sophistication of attacks continues to increase. From machine learning exploitation to fileless malware, threat actors are pushing the boundaries of what's possible. This escalation demands more advanced detection and analysis capabilities from security teams[2].

For organizations, these trends have several important implications:

1. Investment in threat intelligence is becoming non-negotiable. As the Group-IB CEO emphasized, organizations can no longer treat threat intelligence as optional. Understanding the specific threats targeting your industry and technology stack is essential for effective security resource allocation.

2. Collaboration is critical. No single organization can maintain comprehensive visibility into all threat actors. Participation in information sharing communities, whether formal ISACs or informal networks, provides essential perspective on emerging threats.

3. Human factors remain the weakest link. The success of groups like Scattered Spider in using social engineering highlights the continued importance of security awareness training and robust authentication processes.

4. Standardization efforts deserve support. Initiatives like the Shared Threat Actor Glossary can significantly enhance the utility of threat intelligence. Organizations should encourage and participate in such standardization efforts.

As we move forward, the integration of threat intelligence into broader security operations will likely accelerate. Rather than existing as a separate function, threat intelligence is increasingly becoming the foundation that informs all security activities, from vulnerability management to incident response[5].

Looking Ahead: The Future of Threat Intelligence

The developments of the past week point to a future where threat intelligence becomes more collaborative, more standardized, and more deeply integrated into security operations. The Microsoft-CrowdStrike glossary may be just the beginning of broader industry efforts to create common frameworks for understanding and communicating about threats.

We're also likely to see increased automation in threat intelligence processing. As the volume of threat data continues to grow, human analysts alone cannot keep pace. Machine learning and artificial intelligence will play increasingly important roles in identifying patterns and correlations across vast datasets[2][5].

For security professionals, these changes mean both challenges and opportunities. The field of threat intelligence is evolving rapidly, requiring continuous learning and adaptation. But these developments also promise to make threat intelligence more accessible and actionable, even for organizations with limited security resources.

As we navigate this evolving landscape, one thing remains clear: understanding the adversary is no longer a luxury—it's a necessity for effective cybersecurity. The organizations that thrive will be those that embrace this reality and make threat intelligence a cornerstone of their security strategy.
