Unauthorized Group Accesses Anthropic’s Mythos Security Tool

A group of unauthorized users reportedly accessed Mythos, the cybersecurity tool recently announced by Anthropic, during its limited Claude Mythos Preview release. Bloomberg reported that a private online forum gained entry the same day of the public announcement through a third-party vendor environment, allegedly by guessing the model’s online location based on Anthropic’s prior formatting patterns and leveraging contractor access. The group, active on Discord and focused on unreleased AI models, shared screenshots and a live demo as proof. Anthropic told TechCrunch it is investigating and has found no evidence its systems were affected. Mythos was released to select vendors, including Apple, under Project Glasswing.

Vercel Breached via Compromised Google Workspace OAuth App

Vercel, a major web app hosting and deployment platform, was breached through a compromised third-party AI tool’s Google Workspace OAuth application, an attack that impacted hundreds of users across multiple organizations. ShinyHunters — the group behind the recent Rockstar Games hack — posted stolen employee names, email addresses, and activity timestamps online while attempting to sell the data.

Vercel confirmed the incident on X, stating it affected a limited customer subset. Administrators are urged to audit activity logs, rotate environmental variables, check for exposed API keys, and review connected apps for the malicious OAuth application.

Canada’s Liberals Move to Revive Online Speech Legislation

Canada’s Liberal government under PM Mark Carney, with Culture Minister Marc Miller signaling imminent action, is reviving online speech legislation. The Department of Industry confirmed a new “online safety regime” giving government unilateral power to define “harm.” The reconvened Expert Advisory Group — including Bernie Farber of the Canadian Anti-Hate Network — will shape those definitions.

A new Liberal majority, secured through byelection wins and five MP defections, eliminates barriers that previously killed Bills C-63 and C-36. Violations could carry penalties up to $70,000 or house arrest. The Justice Centre for Constitutional Freedoms has launched a national opposition campaign.

Crypto Scam Targets Shipping Chaos in Strait of Hormuz

Crypto scammers are exploiting disruption in the Strait of Hormuz, where thousands of vessels remain stranded amid ongoing regional conflict. On April 20, MARISKS warned that fraudsters posing as Iranian authorities were demanding bitcoin or tether “transit fees,” taking advantage of confusion around Iran’s own crypto-based transit demands.

One ship may have been scammed on April 18, while about 2,000 ships and 20,000 mariners remain stuck. On April 22, the cargo ship Epaminondas was fired upon after reported clearance, with authorities investigating possible fraudulent messages. Maritime security reports cite 22 attacks and 13 suspicious incidents amid escalating military activity and a US Navy blockade.

Mastodon and Bluesky Hit by DDoS Attacks in Rapid Succession

Mastodon’s flagship server, Mastodon.social, was struck by a major DDoS attack on April 20th, causing a significant outage from 1 PM until mitigations restored access by 4 PM. Full recovery was confirmed the following morning. The attack followed a similar hit on Bluesky just days earlier, for which pro-Iran hacktivist group 313 Team claimed unverified responsibility.

No group claimed the Mastodon attack. Both platforms rose to prominence as decentralized alternatives to X following Elon Musk’s acquisition, potentially making them high-profile targets.

Ethereum gateway domain hijacked on our watch.
(via The Cobbler’s Children Have No Shoes dept.)

Every week we talk about (in Joey’s favourite phrase [on the podcast]LINK THIS) “the very best in data-breachin’ over-reachin'” and after many years reporting on it, our turn’s come up and we have to take ownership of one.

Last weekend ETH.LIMO, the ENS gateway domain that provides a web-native bridge to .ETH domains was successfully hijacked via a social engineering attack against us. It was the first successful social engineering event in our 28 year history.

It is important to emphasize that this was not a software or data breach, and it did not affect any systems nor any other customers – they gamed our processes and they pulled it off, however briefly.

Also interesting to note, DNSSEC saved the day in this case.

It goes without saying, we’ve learned from his and already made structural changes to our processes.
