⚠️ Last week saw a range of high-impact incidents, from the Miasma worm compromising 73 Microsoft GitHub repositories to targeted mailbox espionage and an Instagram account compromise via an AI support tool. Vendors patched active Android flaws, researchers flagged malicious npm packages and a compromised Hola Browser installer, and U.S. agencies disrupted transnational investment fraud. Multiple threat clusters, including China-linked espionage groups and financially motivated actors, broadened their geographic scope and tactics, while many critical CVEs remain urgent for defenders to patch.

🔒 Oxford University disclosed a data breach after its third-party provider, Group GTI, reported that the CareerConnect platform was compromised on May 28. The attackers accessed users' first and last names, email addresses, and encrypted passwords for accounts not using Single Sign-On; GTI has invalidated those passwords and will require resets. The university said no course materials, uploaded files, appointments, or financial data appear affected, but warned users to watch for phishing attempts.

🔒 Meta disclosed that a bug in its AI-powered High Touch Support (HTS) tool allowed attackers to request password reset links to email addresses not associated with targeted Instagram accounts, enabling unauthorized access where two-factor authentication was not enabled. The issue was discovered on May 31, affecting 20,225 users and exposing contact details, profile data, posts, messages and activity history. Meta disabled the HTS tool, invalidated reset links, enforced mandatory security checkpoints on impacted accounts, and instructed users to reset passwords and enable 2FA while it reviews recovery flows.

🛡️ Microsoft's GitHub organizations — including Azure, Azure-Samples, Microsoft, and MicrosoftDocs — were hit by the self-replicating Miasma supply chain campaign that affected 73 repositories, prompting GitHub to disable access. The incident notably re-compromised the durabletask package previously infected by TeamPCP, suggesting lingering credential exposure. Miasma, a variant of the Mini Shai-Hulud worm, has mutated rapidly and pushed malicious payloads both to registries and directly to GitHub source repos, leveraging AI coding tools and developer workflows to execute payloads. Security firms warn the campaign exploits trust in maintainers and signing rather than platform vulnerabilities, allowing widespread propagation across the open-source ecosystem.

🔐 Toshiba and Muji warned visitors about unexpected sign-in pop-ups generated by the external service polyfill.io, advising users to cancel and change passwords if they entered credentials. The prompts were caused by remnants of a 2024 incident when the polyfill domain served malicious scripts after changing hands; the domain began responding again in late May 2026 with HTTP 401 requests. Both companies suspended the service and removed the offending code, and other Japanese sites were also affected.

The organization warned recipients to be cautious of impersonation or phishing attempts and said assistance programs will continue as normal for registered beneficiaries.

🔒 Over May 6–7, 2026, Canvas LMS users encountered a defaced login page claiming a ShinyHunters extortion of Instructure, alleging theft of 3.65TB of data affecting about 275 million students, faculty, and staff across nearly 9,000 institutions. Instructure identified an exploited support-ticket vulnerability in its Free for Teacher environment and temporarily disabled that service while investigating. The incident disrupted finals and highlighted risks from centralized SaaS platforms, third-party dependencies, communications breakdowns and the evolving economics of extortion.

🔐 Dashlane disclosed a brute-force attack on May 31, 2026, targeting certain personal accounts to bypass two-factor authentication and register new devices. Its security controls triggered temporary suspensions and authentication issues, and although access has been restored, attackers succeeded in downloading encrypted vaults for fewer than 20 personal-plan users. Dashlane stressed that vault contents remain protected by each user's Master Password and that its internal systems were unaffected.

🛏️ The Play ransomware group claims to have stolen confidential MyPillow data and threatened a public dump, while CEO Mike Lindell denies any breach and calls the allegations politically motivated.
