Inside the Attacker's Mindset: 4 Habits of Highly Effective Red Teams

Red Teamers are often thought of as boundary-pushing hackers, who boldly adopt an attacker’s mindset in an attempt to break into a seemingly secure system or infiltrate a network. In order to thwart an attacker, you need to think like one. But in reality, a Red Teamer’s mindset is far more disciplined and methodical. For the practitioners on the front lines, true offensive security is about the quiet, relentless, and often unglamorous work that makes a realistic test of an organization's defenses possible.

This work happens long before an engagement begins, in the spaces between contracts and behind the scenes. It's a craft built on specific, repeatable habits that separate an elite red team from a simple penetration test. Based on candid conversations with these frontline experts, we’re pulling back the curtain to reveal four essential habits that define the industry's best.

1. They Master the "Boring" Background Work

The most visible part of a red team engagement—the active attack—is just the tip of the iceberg. The real work, the foundation of a successful operation, is the "boring background work" that happens between engagements. For every hour spent actively targeting a network, there are often three or more hours dedicated to preparation. This is the unseen engine of the entire operation.
‍

This work includes:

Deep Threat Intelligence Analysis: This goes beyond reading headlines. It means combing through technical reports on new adversary techniques, understanding how a new malware strain operates, and knowing what real-world threat actors are doing right now. This ensures the simulation is current and relevant.

Custom Tool and Exploit Development: While off-the-shelf tools have their place, they are often easily flagged by modern defensive solutions. Elite red teams invest significant time writing their own exploits or heavily modifying existing tools to bypass specific security products. This custom tradecraft is what allows them to accurately mimic the sophistication of a determined adversary.

Meticulous Social Engineering Prep: A convincing pretext is a work of art built on detailed research. A successful red team doesn't just send a generic phishing email. They build entire campaigns. For example, knowing a company's office is near a marathon route, they might create a fake registration page to harvest credentials. In one case, a team set up a fake website for a new coffee shop near the target's head office, offering free coffee for signing up. This gave them names, email addresses, and, crucially, examples of common password patterns used by employees. This is the level of detail that defines professional offensive operations.

2. Red Teamers Think Like the Business, Not Just an Attacker

Technical skill is a prerequisite for a red teamer, but what elevates an operation from good to great is the ability to understand business context. A technical breach that doesn't impact a critical business function is merely an academic exercise. A red team's true value is in demonstrating risk to the organization.

Knowing how to break in is one thing; knowing what to target is another. One veteran red teamer I know found an innocuous-looking password and, lacking a deep understanding of the client's financial operations, didn't initially recognize its importance. It turned out to be the master key to the organization's most critical systems. This experience underscores a vital lesson: the most effective red teamers have business acumen. They can translate their technical findings into tangible business risks, making their reports resonate with executive leadership and driving real change.

3. They Live by the Principle: "Don't Test in Live"

With adversary TTPs and defensive tools changing constantly, the single most important principle for a professional red teamer is to never test their tools on a live target. What worked last week is not guaranteed to work this week. Getting caught mid-engagement because of an untested payload can jeopardize an entire operation, which can be a multi-month, high-cost investment.

This involves painstakingly building a simulated "sparring" environment that looks exactly like the target's. This means using the same tooling, the same software versions, and the same security configurations to run payloads and test attack paths first. This disciplined habit is what separates professionals from amateurs. It allows the team to understand precisely how their actions will interact with the target environment, find ways to bypass specific defenses, and ensure that when the attack is launched, it's done with precision and control.

4. They Know Their Ultimate Goal: Improve Detections, Not Just Break Things

While it may seem counterintuitive, the ultimate goal of a red team is to make the blue team better. A common mistake is for organizations to view a red team report as simply a list of vulnerabilities to be patched. The real value, however, is in using the report to improve the organization's detection capabilities.

To achieve this, an elite red teamer must possess skills that go beyond the keyboard:

The ability to write detection rules: A red teamer who doesn't understand how a good detection rule is constructed can't effectively advise the blue team on how to improve theirs. The engagement should provide the blue team with the intelligence they need to write better, more resilient detections.

Excellent soft skills: The relationship between red and blue teams can be tense. As one expert noted, the blue team is "always going to be pissed off" initially, because someone has been hired to prove they can't do their job. A successful Red Teamer needs the communication and collaboration skills to navigate this dynamic, build trust, and turn the post-engagement debrief into a true "Purple Team" moment of knowledge transfer and collaboration. As one veteran put it, "I don't care how good someone is technically. If they can't talk to a senior leader or a client, they're not going to get anywhere".

This focus on collaborative improvement is the final, and perhaps most important, piece of "The Real Work." It's this complete cycle of deep research, business-focused planning, disciplined testing, and collaborative partnership that allows an organization to truly prove and improve its cyber resilience.
