FBI Issues Warning on Kali365 Phishing Kit Targeting Microsoft 365 Accounts
In April 2026, the FBI identified 'Kali365,' a Phishing-as-a-Service (PhaaS) platform that enables attackers to hijack Microsoft 365 accounts by stealing OAuth tokens, effectively bypassing multi-factor authentication (MFA). Distributed primarily via Telegram, Kali365 provides AI-generated phishing lures and automated campaign templates, allowing even low-skilled cybercriminals to gain unauthorized access to services like Outlook, Teams, and OneDrive without needing user credentials. ([ic3.gov](https://www.ic3.gov/PSA/2026/PSA260521?utm_source=openai)) The emergence of Kali365 underscores a significant shift in phishing tactics, highlighting the increasing sophistication and accessibility of PhaaS platforms. This development emphasizes the urgent need for organizations to enhance their security measures beyond traditional MFA, as attackers continue to exploit legitimate authentication workflows to gain unauthorized access.

Critical HTTP/2 Bomb Vulnerability Threatens Major Web Servers
In June 2026, cybersecurity researchers identified a critical remote denial-of-service (DoS) vulnerability, termed 'HTTP/2 Bomb,' affecting major web servers including NGINX, Apache HTTPD, Microsoft IIS, Envoy, and Cloudflare Pingora. This exploit leverages the HPACK header compression scheme in HTTP/2, allowing a single attacker to rapidly exhaust server memory by sending minimal data that results in significant memory allocation. A single client on a standard home internet connection can consume up to 32GB of server memory in approximately 20 seconds, rendering the server inaccessible. The discovery of the HTTP/2 Bomb underscores the evolving nature of cyber threats targeting foundational internet protocols. This incident highlights the necessity for continuous vigilance and prompt patching of server software to mitigate emerging vulnerabilities. Organizations are advised to review and adjust their HTTP/2 configurations to prevent potential exploitation.

VS Code Vulnerability Exposes GitHub OAuth Tokens to Attackers
In June 2026, a critical vulnerability was disclosed in Microsoft Visual Studio Code (VS Code) that allowed attackers to steal GitHub OAuth tokens through a single malicious link. Security researcher Ammar Askar demonstrated that by exploiting the webview implementation in VS Code, an attacker could execute malicious JavaScript to install a rogue extension, thereby capturing OAuth tokens with full read and write access to a user's repositories, including private ones. This vulnerability posed significant risks to developers, potentially exposing sensitive code and intellectual property. This incident underscores the growing threat of supply chain attacks targeting development environments. As developers increasingly rely on integrated tools and extensions, the security of these components becomes paramount. Organizations must remain vigilant, ensuring that their development tools are secure and up to date to prevent unauthorized access and data breaches.

CISA Adds Two Known Exploited Vulnerabilities to Catalog
On June 2, 2026, the Cybersecurity and Infrastructure Security Agency (CISA) added two vulnerabilities to its Known Exploited Vulnerabilities (KEV) Catalog: CVE-2022-0492, a Linux Kernel Improper Authentication Vulnerability, and CVE-2025-48595, an Android Framework Integer Overflow Vulnerability. Both vulnerabilities are actively exploited, posing significant risks to federal enterprises. CVE-2022-0492 allows unauthorized access to Linux systems, while CVE-2025-48595 enables local privilege escalation on Android devices without user interaction. ([nvd.nist.gov](https://nvd.nist.gov/vuln/detail/CVE-2025-48595?utm_source=openai)) The inclusion of these vulnerabilities in the KEV Catalog underscores the critical need for organizations to promptly address known security flaws. With active exploitation in the wild, timely remediation is essential to mitigate potential threats and protect sensitive information.
