+# Amendment proposal to TLP 2.0
+
+# The need for TLP:UNCLEAR 
+
+### **0. Rationale and description**
+
+“ELOQUENCE, n. The art of orally persuading fools that white is the color that it appears to be. It includes the gift of making any color appear white.” 
+
+- Ambrose Bierce (excerpted from The Devil’s Dictionary)
+
+Modern approaches to cybersecurity embrace data science, machine learning, and in general the statistical view of the world (or at least the bits on the internet). After all, it makes more sense, when measuring indicators of compromise at scale, to choose a stochastic approach. Therefore, measurements should always be given with a precisely specified indication of uncertainty.
+
+It logically follows that the TLP standard[^1] should also embrace stochastics. In other words, cybersecurity is full of uncertainty which needs to be properly classified into a new taxonomy. And with the advent of ChatGPT, statements on truth become even more … stochastic.
+
+We therefore humbly propose the introduction of **TLP:UNCLEAR**.
+
+
+### **1. Overview**
+
+This amendment shall describe a new Traffic Light Protocol tag: **TLP:UNCLEAR.**
+
+TLP:UNCLEAR MAY be used whenever the sender is not sure which TLP label would be appropriate. Recent epidemiological studies have demonstrated that the rate of TLP:UNCLEAR labelings was strongly correlated with the number of people reading the TLP-SIG mailing lists over an extended period of time. A second cohort of TLP:UNCLEAR labelers was identified at CIRCL.lu in Luxembourg after the introduction of TLP:CLEAR (the so-called “anarcho-undo-clear-labellers”).
+
+**Color code**: when not looking at it, the real color was estimated to be **Schrödinger's Grey or Gray **(itself an TLP:UNCLEAR spelling of an unclear color)**, **however active observers at FIRST conferences described it as dark blue on black background. See figure 1.

+
+
+### **2. Motivation and use-cases**
+
+**TLP:UNCLEAR** label originally emerged in the anarcho-undo-clear-labellers fraction (“patient 0”). It was created in resistance to the renaming of **TLP:WHITE** to TLP:CLEAR. For this group the only logical _undo_ function to the controversial TLP:CLEAR tag was to introduce TLP:UN-CLEAR[^2]. However, soon it was noted that the introduction of TLP:UNCLEAR also had a couple of unexpected beneficial side-effects as well as alternative use-cases:
+
+
+
+* TLP:UNCLEAR helps with the introduction of more statistical methods such as “AI” and Deep Learning into the field of Cybersecurity. Without TLP:UNCLEAR, statistical statements on IoCs would not be possible (“is this IP address a C&C server or not?” -> TLP:UNCLEAR)
+* TLP:UNCLEAR becomes extremely practical when trying to describe the confusion of different levels of TLP:AMBER. Whenever there are uncertainties between TLP:AMBER, TLP:AMBER-strict, TLP:YELLOW (or what’s the difference to amber? Is it traffic lights or not or what?), TLP:you-can’t-tell-your-spouse-but-everyone-else, TLP:share-with-your-customers-but-not-your-boss, then, TLP:UNCLEAR can easily come to the rescue: by confusing the hell out of the recipient of an TLP:UNCLEAR message into a petrified state, no action will be taken on TLP:UNCLEAR messages, which is after all the intended outcome.
+* When your boss asks you for an assessment on the latest cyber breach on Friday evening and you just don’t have an answer yet…it’s going to be labeled TLP:UNCLEAR
+* You just had a meeting about an incident, so many people had their own opinion about what can or cannot be shared. Until it’s settled or the next ransomware campaign leaks the meeting notes, TLP:UNCLEAR can be used.
+* If your software doing threat intelligence is buggy and running into an exception, TLP:UNCLEAR is used for all the output generated from an unknown state.
+* An incident responder finds some information in a drop-zone of a C2 server and doesn’t know what to do with it, TLP:UNCLEAR can come to the rescue. 
+* The cybercrime data came from the U.N., and is thus de facto TLP:UNCLEAR.
+* Is GPT5 going to become sentient? → TLP:UNCLEAR
+
+
+### **3. TLP definitions update proposed**
+
+The following addendum is proposed to “FIRST Standards Definitions and Usage Guidance — Version 2.0”
+
+**Community:** Under TLP, a _community_ is a group who shares common goals, practices, and informal trust relationships. A community can be as broad as all cybersecurity practitioners in a country (or in a sector or region). 
+
+**Organization:** Under TLP, an _organization_ is a group who share a common affiliation by formal membership and are bound by common policies set by the organization. An organization can be as broad as all members of an information sharing organization, but rarely broader. Crucially, an organization is defined by the ability to disorganize the information it seeks to share[^3][^4].
+
+**Clients:** Under TLP, clients are those people or entities that receive cybersecurity services from an _organization_. Clients are by default included in TLP:AMBER so that the recipients may share information further downstream in order for clients to take action to protect themselves. For teams with national responsibility this definition includes stakeholders and constituents.
+
+E. <span style="color:blue; background: #000;">TLP:UNCLEAR</span> Community, Organization, Clients, and Recipients are all so confused what the appropriate disclosure level is, and if this or that indicator can or cannot be shared. Assumptions are rampant and the confusion is so high that a chi-square test might in fact be required to ensure the randomness of the mess before labelling this case TLP:UNCLEAR.
