In a rapidly shifting threat landscape, attackers are constantly reinventing their methods and leaving many organizations’ defenses struggling to keep up. According to a recently published article from Help Net Security, security coverage that worked yesterday may not effectively detect or stop how attackers behave today. Help Net Security
The 2025 Threat-Led Defense Report from Tidal Cyber reveals that cybercriminals are not just using new tools, they are changing how they operate. By tracking tens of thousands of real-world attacker procedures and mapping them to the MITRE ATT&CK framework, the study highlights how tactics, techniques, and procedures evolve—even within the same threat group.
Attackers Move Faster and Smarter
Threat actors like Void Rabisu and Scattered Spider are expanding their objectives and environments. Void Rabisu shifted from traditional ransomware into espionage-aligned campaigns targeting telecom, energy, and government sectors. Scattered Spider, active from 2022 through 2025, has broadened its reach into retail, technology, and finance, exploiting SaaS platforms like Salesforce, Microsoft Teams, Slack, and SharePoint.
Meanwhile, groups such as Akira ransomware operations have continued refining their procedures around credential theft, data exfiltration, and recovery inhibition using familiar but subtly altered command behaviors.
Zero-Day Exploits Are No Longer Rare
One of the most concerning trends is the widespread use of zero-day exploits by both state-sponsored and criminal groups. The report identified more than 50 threat objects tied to zero-day activity, showing that once niche tools have become commoditized and quickly weaponized.
Because zero-day attacks can move from discovery to active exploitation in a matter of days—or even hours—traditional defenses that wait for vulnerability disclosures or rely on patch cycles are left scrambling. Timely protection now depends on identifying harmful behavior, not just known vulnerabilities.
Social Engineering Resurges
The report also found that social engineering has regained prominence, driven in part by AI automation that scales phishing, voice spoofing, and credential harvesting with unprecedented speed and accuracy. Identity systems, cloud administration interfaces, and single sign-on mechanisms are now primary targets.
Groups such as Luna Moth and UNC6040 are using multi-channel tactics—including email, voice, and infrastructure permission abuse—to bypass traditional endpoint protections altogether.
Fragmented Ransomware and Shifting Motives
Ransomware operations continue to fragment and diversify, with 54 distinct ransomware groups tracked in 2025 and 16 new entities emerging. Rather than relying solely on encryption, many threat actors now focus on data theft, identity compromise, and business disruption as part of double or triple extortion schemes.
This shift means defenders can no longer rely solely on signature detection or typical ransomware defenses; modern ransomware campaigns incorporate a blend of tactics designed to evade detection and maximize operational impact.
The Real Problem: Behavior Over Tools
The key takeaway from the Tidal Cyber report is that traditional detection tools are struggling not because they are outdated, but because they are focused too narrowly on specific techniques and tools rather than on attacker behavior itself. Even slight procedural changes can cause defenses to fail, leaving a dangerous gap at the core of most security programs.
The research makes one thing clear: strength is measured by the adversary behaviors you can actually stop, and that starts with understanding how attackers operate in the real world—not just what tools they use.
Why Detect and Respond Is Not Enough
Most legacy security solutions rely on “detect and respond.” They generate alerts when something suspicious is identified, then trigger follow-up actions like quarantining, incident analysis, or manual intervention. But when attackers move quickly—often completing lateral movement or data theft in minutes—this reactive model simply cannot keep pace.
Detect and respond waits for an attack to unfold. By the time an alert fires, damage may already be done.
Move to Isolation and Containment
What’s needed is a defense model that prevents malicious behavior from progressing in the first place—even when the specific technique or exploit is unknown. AppGuard takes this approach to endpoint protection by isolating and containing suspicious activity at its source. Instead of relying on signatures, heuristics, or post-facto detection, AppGuard stops unauthorized behavior from ever impacting business systems.
With a proven 10-year track record of protecting high-value targets, AppGuard ensures that even as attackers adapt their methods, your organization remains protected. Its isolation and containment strategy neutralizes threats before they can execute damaging procedures, offering a fundamentally stronger security posture than traditional detect-and-respond solutions.
Time for a Better Defense
The threat landscape will only continue to evolve. Attackers are adapting their procedures, extending across platforms, and innovating faster than defenses that depend on detection can keep up. The evidence from the 2025 Threat-Led Defense Report should be a wakeup call for business leaders and security teams alike.
If your business is still relying on reactive security, you are leaving the door open to threats that can evade detection, steal data, and disrupt operations before alarms ever sound.
Business owners, it is time to talk with us at CHIPS about how AppGuard can prevent this type of incident. Let’s move your organization away from outdated detect and respond strategies to proactive isolation and containment that stops attackers where they begin.
Together, we can build a stronger, more resilient defense that adapts as your adversaries do.
