A sophisticated phishing attack targeted over 35,000 users across 13,000 organizations between April 14-16, 2026, using fake "code of conduct" emails to steal credentials. The attackers used adversary-in-the-middle (AiTM) techniques to bypass multi-factor authentication by hijacking active login sessions in real-time.

The campaign primarily hit the United States (92% of victims) and targeted healthcare, financial services, and technology sectors. Victims received professional-looking emails claiming conduct violations, with PDF attachments leading to fake Microsoft login pages. The attackers positioned themselves between users and legitimate Microsoft services, capturing authentication tokens that provided direct account access without passwords.

Microsoft Defender Research tracked the campaign, noting its use of legitimate email services and polished HTML templates that made detection difficult. Organizations should enable phishing-resistant MFA methods like FIDO keys and implement comprehensive email security measures.

Cybersecurity firm Trellix confirmed a breach of part of its source code repository, though details remain scarce. The company is working with forensic experts and has notified law enforcement. Trellix says there's no evidence its code release process was compromised or that the source code was exploited — but a full investigation is still underway.

The breach may tie into a broader supply chain campaign linked to hacker groups TeamPCP and Lapsus$, which also hit Checkmarx, Aqua Security, and Bitwarden. Attackers reportedly compromised CI/CD pipelines to push malicious updates and steal credentials at scale.

A serious vulnerability in FreeBSD's default DHCP client — tracked as CVE-2026-42511 — lets attackers on the same local network execute commands as root, taking complete control of affected machines. Discovered by Joshua Rogers of the AISLE Research Team, the flaw stems from dhclient(8) failing to properly escape double-quotes when processing DHCP server responses, allowing injected commands to run with full system privileges. Every supported FreeBSD release is affected, including versions 13.5, 14.3, 14.4, and 15.0. Patches are already available. Admins should update immediately — and enabling DHCP snooping on network switches adds an effective extra layer of defense.

A sophisticated hacking campaign hit South-East Asian government and military targets by exploiting CVE-2026-41940, a critical CVSS 9.8 authentication bypass in cPanel and WHM. Attackers gained root-level access without valid credentials before a patch dropped on April 28, 2026. Beyond cPanel, hackers also cracked an Indonesian defense training portal using a CAPTCHA bypass and SQL injection, escalating to full OS access via PostgreSQL. The operation ended with 110 files (~4.37GB) stolen from the China Railway Society, including financial records with national ID numbers and bank details. Shadowserver tracked 44,000 IPs actively scanning for vulnerable servers. Patch cPanel immediately.

A sweeping supply chain attack dubbed "Mini Shai-Hulud," linked to the TeamPCP hacking group, has compromised over 1,800 developer repositories since April 29. Malicious versions of SAP NPM packages, Lightning PyPi (v2.6.2–2.6.3), intercom-client NPM (v7.0.4–7.0.5), and intercom-php (v5.0.2) were injected with credential-stealing malware. The malware harvests AWS keys, API tokens, VPN credentials, crypto wallet data, and more, exfiltrating it to GitHub repos and a dedicated domain. The payload also actively scans Kubernetes environments and HashiCorp Vault secrets. With the affected packages totaling nearly 30 million downloads combined, the blast radius could grow significantly.

Rockstar Games has been hit by hackers for the second time in three years. A group called ShinyHunters — prolific English-speaking teen cybercriminals — claims to have breached servers managed by a third-party cloud provider and is threatening to publish stolen data after Rockstar refused to pay a ransom. Rockstar is downplaying the damage, telling the BBC the incident had "no impact" on the company or its players and that only "a limited amount of non-material information" was accessed. The breach echoes a 2023 hack by British teen Arion Kurtaj, who leaked GTA 6 footage and received an indefinite hospital order.

Researchers at Novee Security uncovered a critical vulnerability in Google's Gemini CLI that allowed attackers to execute arbitrary code on host machines — no prompt injection required. The flaw stemmed from Gemini CLI automatically trusting the current workspace folder, loading any agent configuration found there without sandboxing or human approval. A planted malicious config could expose secrets, credentials, and source code. In CI/CD pipelines, the risk escalated to full supply chain attacks. Google has since patched both Gemini CLI and the run-gemini-cli GitHub Action. The incident highlights a growing concern: AI coding agents now operate with trusted contributor-level access inside developer workflows.

Cybersecurity firm Xint has discovered a critical Linux kernel vulnerability, dubbed "Copy Fail" (CVE-2026-31431), hiding in plain sight since 2017. Using AI-assisted scanning, researcher Tim Becker found a logic flaw in the kernel's cryptography system that lets any unprivileged local user gain full root access — reliably, 100% of the time, with just 10 lines of exploit code.

The bug affects every Linux distribution and leaves zero disk traces, clearing itself on reboot. Real-world risks include Kubernetes container escapes and CI/CD pipeline compromises. A patch is already available. Older, unpatched systems predating 2017 are ironically unaffected.

An AI tool from cybersecurity firm Aisle found 38 previously unknown vulnerabilities in OpenEMR, an open-source electronic health record platform used by over 100,000 healthcare providers globally. Discovered in just three months, the flaws ranged from medium to critical severity and included SQL injection, cross-site scripting, and authorization bypass issues. The worst could have exposed patient health data and handed attackers full server control. All 38 are now patched in versions released in February and March 2025. For comparison, a manual audit in 2018 took far longer and found only 23 flaws. OpenEMR has since built Aisle's tool into its code review process.

What started as a corporate data breach has snowballed into a serious diplomatic rift. South Korean e-commerce giant Coupang disclosed in November that a former employee stole an internal security key, exposing data from 33.7 million users. Seoul launched a sweeping crackdown — police raids, tax audits, parliamentary hearings — but CEO Bom Kim refused to appear. Washington reportedly pushed back, signalling it would pause high-level defence talks unless Kim faced no legal consequences. The fallout has stalled nuclear submarine cooperation talks and drawn 54 Republican lawmakers to accuse Seoul of targeting a US company. Analysts warn the alliance is nearing a "critical threshold of strain."
