Phishing, ataques e privacidade

From the first contact to the permission, key or device an attacker wants.

Many attacks begin outside the blockchain. A convincing interview invitation, a password-reset email or a compromised public account can move a person from a familiar service to an attacker-controlled workflow. The BlockLayerPod and BeaconLayerPod article follows that progression through the accounts, invitations and installation requests reported to MASTR. Read it alongside the account-compromise and reply-bot records to see how reputation is reused as bait.

Other failures occur in software people already trust. Browser extensions, dependencies, release pipelines and embedded signing systems can change the risk without changing the logo on screen. The Trust Wallet, Coldcard and agentic-finance publications examine different parts of that problem. A wallet connection, token approval, leaked session and exposed seed are different events; their consequences and the response they require should not be conflated.

The privacy series adds the information layer. Public transfers, exchange records, infrastructure logs and reused identities can connect activities that a user believed were separate. Its three original posts are presented together. Historical warnings describe the situation then; check the relevant product’s current guidance before acting on an old software version or incident report.

Password-reset emails: what they do and do not reveal

What’s happening is simple: someone, (in this case most likely bots), triggers a password reset request through X’s public reset form. For that, the public username is enough. X then sends the reset email itself to the address linked to the…

Exchange accountability · 28 Aug 2026

If onchain evidence clearly documents a scam, theft or other crime, CEXs should be legally required to hand over the relevant KYC and transaction data to law enforcement when a valid legal request exists.

Paid promotion · 23 Aug 2026

I’ll focus more heavily on bug bounties again. Unless this space decides that this public work, which depends entirely on support, matters enough to keep alive.

Security and verification · 19 Aug 2026

I’m being paid to perform full security assessments on 2 of them, while I gave another 5 only a rough 30-minute pass. Even at that depth, some of the vulnerabilities and basic security failures I found are frankly alarming.

They are organised, patient, funded, technically serious and fully aware that crypto still runs on weak humans, lazy security, rushed integrations and teams that spend more on marketing than on infrastructure hardening.

How AI changes the scale and speed of attacks

AI will multiply the scale, speed and precision of attacks, but the ugly truth is that many of these incidents are not some mysterious act of cyber warfare.
