Google Confirms CVE-2026–21385 in Qualcomm Android Component Exploited
There are currently no details on how the vulnerability is being exploited in the wild. However, Google acknowledged in its monthly Android security bulletin that “there are indications that CVE-2026–21385 may be under limited, targeted exploitation.”
Google’s March 2026 update contains patches for a total of 129 vulnerabilities, including a critical flaw in the System component (CVE-2026–0006) that could lead to remote code execution without requiring any additional privileges or user interaction. In contrast, Google addressed one Android vulnerability in January 2026 and none last month.
Also patched by Google are multiple critical-rated bugs: a privilege escalation bug in Framework (CVE-2026–0047), a denial-of-service (DoS) in System (CVE-2025–48631), and seven privilege escalation flaws in Kernel components (CVE-2024–43859, CVE-2026–0037, CVE-2026–0038, CVE-2026–0027, CVE-2026–0028, CVE-2026–0030, and CVE-2026–0031).
Fake Tech Support Spam Deploys Customized Havoc C2 Across Organizations
Threat hunters have called attention to a new campaign as part of which bad actors masqueraded as fake IT support to deliver the Havoc command-and-control (C2) framework as a precursor to data exfiltration or ransomware attack.
The intrusions, identified by Huntress last month across five partner organizations, involved the threat actors using email spam as lures, followed by a phone call from an IT desk that activates a layered malware delivery pipeline.
“In one organization, the adversary moved from initial access to nine additional endpoints over the course of eleven hours, deploying a mix of custom Havoc Demon payloads and legitimate RMM tools for persistence, with the speed of lateral movement strongly suggesting the end goal was data exfiltration, ransomware, or both,” researchers Michael Tigges, Anna Pham, and Bryan Masters said.
CISA flags VMware Aria Operations RCE flaw as exploited in attacks
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a VMware Aria Operations vulnerability tracked as CVE-2026–22719 to its Known Exploited Vulnerabilities catalog, flagging the flaw as exploited in attacks.
Broadcom also warned that it is aware of reports indicating the vulnerability is exploited but says it cannot independently confirm the claims.
VMware Aria Operations is an enterprise monitoring platform that helps organizations track the performance and health of servers, networks, and cloud infrastructure.
Microsoft: Hackers abuse OAuth error flows to spread malware
Hackers are abusing the legitimate OAuth redirection mechanism to bypass phishing protections in email and browsers to take users to malicious pages.
The attacks target government and public-sector organizations with phishing links that prompt users to authenticate to a malicious application, Microsoft Defender researchers say.
With e-signature requests, Social Security notices, meeting invitations, password resets, or various financial and political topics that contain OAuth redirect URLs. Sometimes, the URLs are embedded in PDF files to evade detection.
