In cybersecurity, identifying an attacker is rarely as simple as discovering a malicious file or tracing a single digital address. Modern threat intelligence depends on understanding patterns over time: who is targeting an organization, what techniques are being used, which systems are repeatedly attacked, and whether the same activity has appeared elsewhere. That is why the names assigned to hacking groups have become an important part of the security industry’s operational infrastructure.

Google is now redesigning the way it assigns those names as the scale of the threat landscape continues to expand. The company’s Google Threat Intelligence Group tracks more than 5,000 activity clusters across multiple countries, illustrating why older naming systems based largely on numerical designations have become increasingly difficult to manage.

The new framework replaces the older APT-style approach inherited from Mandiant with a simpler structure. Google will use a memorable first word combined with a second word whose initial identifies the suspected country of origin. The system includes examples such as Castle for China, Ion for Iran, Neptune for North Korea and Relic for Russia.

The change may look cosmetic from outside the cybersecurity industry, but the underlying objective is operational. Security teams need a consistent way to connect current incidents with historical intelligence. A recognizable identity allows analysts to build a behavioral profile around an attacker rather than treating every intrusion as an isolated event.

That distinction becomes increasingly important as organizations face repeated and overlapping campaigns. An attacker may change malware, infrastructure or individual techniques while retaining broader behavioral characteristics. If those connections can be identified, defenders can potentially detect an intrusion earlier and respond using intelligence gathered from previous incidents.

For Google, naming therefore functions as a form of information architecture.

Shane Huntley, chief technology officer of Google Threat Intelligence Group, has explained that the industry underestimated how quickly the number of identifiable threat groups would grow when security companies began publicly documenting attackers in the early 2010s. What began as a relatively manageable collection of named advanced persistent threats has developed into a much larger ecosystem involving state-sponsored operators, criminal organizations, contractors and hacking-for-hire businesses.

The economic implications are significant. Cybersecurity teams increasingly operate under pressure to process enormous volumes of alerts and intelligence. If threat information is fragmented because different vendors use different names for the same actor, organizations may spend additional time reconciling identities before they can act.

Standardization can reduce that friction, even when complete industry-wide agreement remains unrealistic.

One of the central problems is that cybersecurity companies do not possess identical visibility. Each organization collects different telemetry, observes different customers and operates different detection systems. As a result, two companies may analyze the same hacking operation and reach different conclusions about whether several activities belong to one group or multiple groups.

Google's position is that this disagreement cannot simply be eliminated by exchanging more information. No security provider has complete visibility into the global threat environment, meaning attribution is often based on the best available evidence rather than absolute certainty.

That limitation is particularly relevant when dealing with cybercriminal organizations.

State-sponsored groups tend to be easier to track because their strategic objectives, targets and operating patterns can remain relatively consistent. Criminal groups, by contrast, can be fluid. Members can move between organizations, groups can split, and different actors can reuse tools or techniques. Hacking-for-hire operations add another layer of complexity because the same infrastructure or expertise can potentially serve customers in different countries.

This makes the distinction between an established actor and a temporary cluster of activity critical for defenders.

The naming system also has a communication function. Cybersecurity professionals, government agencies, policymakers and corporate executives need to discuss threats without repeatedly describing long technical indicators. A memorable codename can act as a shorthand for a much larger body of intelligence.

That is especially useful during an active incident. When an organization discovers that it may be facing an actor with a known history, the value of the name is not the name itself but the information attached to it: previous targets, techniques, objectives, infrastructure and observed behavior.

The result is a shift in how threat intelligence should be viewed. Hacker names are not simply labels created for reports or headlines. They are organizational tools that allow large amounts of security information to be indexed and reused.

Google's consolidation of its previous threat-tracking naming practices with those inherited through Mandiant is therefore part of a broader effort to simplify its internal intelligence ecosystem. Mandiant had pioneered the use of structured names for threat groups, while Google's Threat Analysis Group developed its own tracking approach. Bringing those systems together reduces the number of competing naming conventions within the same organization.

The larger industry challenge, however, remains unresolved. There is no universal authority capable of assigning one definitive name to every hacking group, and the fragmented nature of cyber intelligence makes that difficult to achieve.

Instead, the future of threat intelligence is likely to depend on interoperability between different datasets, clearer attribution methodologies and stronger links between names and behavioral intelligence.

For businesses, the practical lesson is straightforward: the identity of an attacker matters because it can influence the speed and quality of the defensive response. Security teams that understand who is attacking them, how that actor typically operates and what it has previously targeted are better positioned to prioritize defenses and investigate suspicious activity.

As cyberattacks become more frequent and increasingly organized, that intelligence advantage has direct financial value. Faster identification can reduce investigation time, limit operational disruption and potentially prevent a compromise from expanding into a larger incident.

Google's naming overhaul therefore represents more than a branding exercise. It reflects a cybersecurity market in which the volume of threat activity has grown beyond what informal or fragmented tracking systems can comfortably handle.

The evolution of hacker names mirrors the evolution of cyber threats themselves. As attackers become more numerous, adaptable and difficult to distinguish, the ability to organize intelligence around persistent patterns becomes increasingly important.

In that environment, a codename is useful not because it gives a hacker a memorable identity, but because it provides defenders with a handle for everything they already know—and everything they may discover next.
