Microsoft on Monday warned of phishing campaigns that employ phishing emails and OAuth URL redirection mechanisms to bypass conventional phishing defenses implemented in email and browsers. The activity, the company said, targets government and public-sector organizations with the end goal of redirecting victims to attacker-controlled infrastructure without stealing their tokens. It described the phishing attacks as an identity-based threat that takes advantage of OAuth's standard, by-design behavior rather than exploiting software vulnerabilities or stealing credentials. "OAuth includes a legitimate feature that allows identity providers to redirect users to a specific landing page under certain conditions, typically in error scenarios or other defined flows," the Microsoft Defender Security Research Team said . "Attackers can abuse this native functionality by crafting URLs with popular identity providers, such as Entra ID or Google Workspace, that use manipu...

Google on Monday disclosed that a high-severity security flaw impacting an open-source Qualcomm component used in Android devices has been exploited in the wild. The vulnerability in question is CVE-2026-21385 (CVSS score: 7.8), a buffer over-read in the Graphics component. "Memory corruption when adding user-supplied data without checking available buffer space," Qualcomm said in an advisory, describing it as an integer overflow. The chipmaker said the flaw was reported to it through Google's Android Security team on December 18, 2025. Customers were notified of the security defect on February 2, 2026. 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 critica...

The threat activity cluster known as SloppyLemming has been attributed to a fresh set of attacks targeting government entities and critical infrastructure operators in Pakistan and Bangladesh. The activity, per Arctic Wolf, took place between January 2025 and January 2026. It involves the use of two distinct attack chains to deliver malware families tracked as BurrowShell and a Rust-based keylogger.  "The use of the Rust programming language represents a notable evolution in SloppyLemming’s tooling, as prior reporting documented the actor using only traditional compiled languages and borrowed adversary simulation frameworks such as Cobalt Strike, Havoc, and the custom NekroWire RAT," the cybersecurity company said in a report shared with The Hacker News. SloppyLemming is the moniker assigned to a threat actor that's known to target government, law enforcement, energy, telecommunications, and technology entities in Pakistan, Sri Lanka, Bangladesh, and China since ...

Cybersecurity researchers have disclosed details of a now-patched security flaw in Google Chrome that could have permitted attackers to escalate privileges and gain access to local files on the system. The vulnerability, tracked as CVE-2026-0628 (CVSS score: 8.8), has been described as a case of insufficient policy enforcement in the WebView tag. It was patched by Google in early January 2026 in version 143.0.7499.192/.193 for Windows/Mac and 143.0.7499.192 for Linux. "Insufficient policy enforcement in WebView tag in Google Chrome prior to 143.0.7499.192 allowed an attacker who convinced a user to install a malicious extension to inject scripts or HTML into a privileged page via a crafted Chrome extension," according to a description on the NIST National Vulnerability Database (NVD). Palo Alto Networks Unit 42 researcher Gal Weizman, who discovered and reported the flaw on November 23, 2025, said the issue could have permitted malicious extensions with basic permissi...

Google has announced a new program in its Chrome browser to ensure that HTTPS certificates are secure against the future risk posed by quantum computers . "To ensure the scalability and efficiency of the ecosystem, Chrome has no immediate plan to add traditional X.509 certificates containing post-quantum cryptography to the Chrome Root Store ," the Chrome Secure Web and Networking Team said . "Instead, Chrome, in collaboration with other partners, is developing an evolution of HTTPS certificates based on Merkle Tree Certificates (MTCs), currently in development in the PLANTS working group." As Cloudflare explains, MTC is a proposal for the next generation of the Public Key Infrastructure (PKI) used to secure the internet that aims to reduce the number of public keys and signatures in the TLS handshake to the bare minimum required. Under this model, a Certification Authority (CA) signs a single 'Tree Head' representing potentially millions of certi...
