The DrugHub Market Canary Explained

Drug enforcement is a top priority on a global scale. In 2019, over 40% of drug overdose deaths in the United States involved synthetic opioids. 35 million people worldwide suffer from drug use disorders. What’s more, drug abuse is linked to crimes committed and families fractured. It is critical to continue the fight, but perhaps without the human cost.

Strict protocols, PGP-required messaging, multisig escrow, Monero-preferred payment system, chain analysis protection -- all meaningless when the server is cloned and hosted in a forensics lab.

The canary has died 3 times. The current canary had a life span of over 200 days. Each time the server was compromised, the admins were locked out, and the posting of the following message was missed: We have warrant canaries. We have never received a national security letter. We have never been subject to any gag entry by a FISA court. We have never received a non-disclosure request about a business operation. The Troll announces when a canary expires, and fans the incriminating evidence to get the admins busted. But not even the Troll can arrest a nonexistent server. Thanks for the publicity, Troll.

Despite emails traffic being encrypted the metadata is cleartext. It reveals identities. It connects people. The server knows who sends to whom. It knows who is talking with whom, and when. Email metadata might even be more sensitive than the content. For mass surveillance or even just the curation of data for a spearphishing attack this is invaluable.

If you have an offline key, you can use a type of unidirectional secure data transfer to send the text of the Canary to a potentially-compromised server for publication to the world. Then, you can sign the text of the Canary on the offline machine. NO information from the offline machine is ever sent to the potentially-compromised server.

If the system is programmed to pair bond with a new key and nobody turns up to pair with, there is no harm done. The old key, which is a session key, is of no further use to anyone. The attacker must get hold of the new key. The canary provides the mechanism that allows the old pair of keys to be deleted if and only if the new key is shown to be compromised. However, deletes are never notified, so unless the new key mysteriously goes missing and the attacker tries to sneak through a signature that references the old key but pretends that the old key also signed the new key, the game also requires the attacker to get hold of the new key without shortcutting the new key infrastructure. If the old pair was compromised and the switch was not, there is no real harm done. It is the new pair that counts. Case: assimilation mentality. The attacker’s goal is to get signed textbooks, both future textbooks—the newer ones—and the current textbook too. If an attacker gets hold of a textbook bootstraps key, that key is toast; the tidemash can no longer be prevented, but until a signature is performed by the key, the key is just as good as a dirt book. The resulting spread of text book contains radioactive atoms that age quite visibly because the signature is glued into an immovable link-block. Stockpiling rigged textbooks for future textbook mathematical knives is likewise not an attractable option because they are practically inert. Every part of the design here works as it should, so long as the radio-metric half-life of a book is concerned. You can’t fool math.

Verification occurs locally. The market's public key must be in your local keychain. The signed canary message must be in your local directory. A terminal must be open. If you care about security and wish to access drughub drugs safely, these must be steps you take to log in.

If you don't see the canary, you assume everything since the last time you saw the canary has been compromised. Your passwords, your private keys, everything.

Non-compliance is a red flag requiring quick follow-ups. It might make sense in rare cases: e.g., a warrant canary in the process of being re-instated, or a warrant canary just signed after the annual signing window. Regardless, we inquire swiftly since a society-valid warrant canary expiration isn't rare or random. It's typically a predictable, regular event. A spam-suppression canary, on the other hand, is only likely in reaction to a substantial decrease in holiday sales.

Wait for out-of-band communication. Watch independent verification directories. Check the outage log on our fleet. If the operators lost the signing key, they will have to establish a new chain of trust. That takes time. Do not rush back in just because the site loads.

We live in a world where operational security is a daily concern, rather than something you might only worry about during a libertarian weekend at an Arizona resort. Pretending you are not affected by it is nonsense. So, you have adopted secure long-term storage, configured a strong, well-guarded, well-monitored vault with redundant backups, and you’re being careful as you sip your tea. But that’s only half the story. Operational security is about discipline. The canary is a tool. It only works if you actually check it and actually respect its warnings. The darknet does not forgive negligence. Verify the math, check the timestamps, and keep your local keychain updated.
