CloudZ Malware Exploits Microsoft Phone Link to Steal SMS and OTPs
In May 2026, cybersecurity researchers identified a new variant of the CloudZ remote access tool (RAT) that employs a malicious plugin named Pheno to exploit Microsoft's Phone Link application. This malware monitors active Phone Link sessions on Windows 10 and 11 systems, accessing the application's local SQLite database to intercept SMS messages and one-time passwords (OTPs) without compromising the associated mobile device. The attack chain begins with a fake ScreenConnect update, leading to the deployment of a Rust-based loader, followed by a .NET loader that installs CloudZ RAT and establishes persistence via a scheduled task. The .NET loader includes anti-analysis checks to evade detection. ([bleepingcomputer.com](https://www.bleepingcomputer.com/news/security/cloudz-malware-abuses-microsoft-phone-link-to-steal-sms-and-otps/?utm_source=openai)) This incident underscores the evolving tactics of threat actors who are increasingly targeting desktop applications that bridge connections to mobile devices. By compromising the Phone Link application, attackers can bypass traditional mobile security measures and directly access sensitive authentication codes, highlighting the need for enhanced security protocols in cross-device applications.

Quasar Linux Malware: A New Threat to Software Developers in 2026
In May 2026, cybersecurity researchers identified Quasar Linux (QLNX), a sophisticated malware targeting software developers' systems. QLNX combines rootkit, backdoor, and credential-stealing functionalities, deploying across development environments like npm, PyPI, GitHub, AWS, Docker, and Kubernetes. It achieves stealth and persistence through in-memory execution, log wiping, process name spoofing, and multiple persistence mechanisms, including LD_PRELOAD and systemd. The malware's capabilities include interactive shell access, file and process management, credential harvesting (SSH keys, browser data, cloud configurations), keylogging, and lateral movement via SSH-based techniques. By compromising developer workstations, QLNX poses a significant supply chain risk, potentially enabling attackers to publish malicious packages to public repositories. ([bleepingcomputer.com](https://www.bleepingcomputer.com/news/security/new-stealthy-quasar-linux-malware-targets-software-developers/amp/?utm_source=openai)) The emergence of QLNX underscores a growing trend of sophisticated malware targeting development environments to facilitate supply chain attacks.

Microsoft Edge's Cleartext Password Storage: A Security Wake-Up Call
In May 2026, security researcher Tom Jøran Sønstebyseter Rønning disclosed that Microsoft Edge decrypts and stores all saved user passwords in cleartext within process memory upon browser launch, retaining them throughout the session. This design allows attackers with administrative privileges to access these credentials, posing significant risks in shared and enterprise environments. Microsoft confirmed this behavior is intentional, stating it is 'by design.' This incident underscores the critical need for organizations to reassess their reliance on browser-based password storage solutions. The exposure of credentials in memory highlights vulnerabilities that can be exploited, emphasizing the importance of adopting dedicated password management tools and implementing robust security policies to mitigate such risks.

Persistent OAuth Tokens: The Unseen Backdoor in Enterprise Security
In May 2026, a significant security concern emerged regarding the widespread use of OAuth tokens in enterprise environments. Employees frequently connect AI tools, workflow automations, and productivity applications to platforms like Google and Microsoft, generating persistent OAuth tokens that often lack expiration dates and are not subject to automatic cleanup. This practice creates a substantial security gap, as these tokens can grant attackers unauthorized access without the need for passwords, bypassing traditional security measures such as multi-factor authentication. The inherent design of OAuth, which does not automatically revoke tokens when employees depart or change passwords, exacerbates this vulnerability. The urgency of addressing this issue is underscored by recent incidents where threat actors exploited OAuth tokens to gain unauthorized access to sensitive data. For instance, in August 2025, attackers used compromised OAuth tokens from the Salesloft-Drift integration to access Salesforce environments of over 700 organizations, leading to significant data exfiltration. ([checkred.com](https://checkred.com/resources/blog/when-oauth-tokens-go-rogue-lessons-from-the-salesloft-drift-breach/?utm_source=openai)) These events highlight the critical need for organizations to implement robust monitoring and management of OAuth grants to prevent similar breaches.
