Threat hunters have disclosed a new "widespread timing-based vulnerability class" that leverages a double-click sequence to facilitate clickjacking attacks and account takeovers in almost all major websites. The technique has been codenamed DoubleClickjacking by security researcher Paulos Yibelo. "Instead of relying on a single click, it takes advantage of a double-click sequence," Yibelo said . "While it might sound like a small change, it opens the door to new UI manipulation attacks that bypass all known clickjacking protections, including the X-Frame-Options header or a SameSite: Lax/Strict cookie." Clickjacking , also called UI redressing, refers to an attack technique in which users are tricked into clicking on a seemingly innocuous web page element (e.g., a button), leading to the deployment of malware or exfiltration of sensitive data. DoubleClickjacking is a variation of this theme that exploits the gap between the start of a click and the...

Google last month addressed a high-severity flaw in its OAuth client library for Java that could be abused by a malicious actor with a compromised token to deploy arbitrary payloads. Tracked as  CVE-2021-22573 , the vulnerability is rated 8.7 out of 10 for severity and relates to an authentication bypass in the library that stems from an improper verification of the cryptographic signature. Credited with discovering and reporting the flaw on March 12 is  Tamjid Al Rahat , a fourth-year Ph.D. student of Computer Science at the University of Virginia, who has been awarded $5,000 as part of Google's bug bounty program. "The vulnerability is that the IDToken verifier does not verify if the token is properly signed," an  advisory  for the flaw reads. "Signature verification makes sure that the token's payload comes from a valid provider, not from someone else. An attacker can provide a compromised token with custom payload. The token will pass the validation on ...

Cybersecurity isn't just another checkbox on your business agenda. It's a fundamental pillar of survival. As organizations increasingly migrate their operations to the cloud, understanding how to protect your digital assets becomes crucial. The shared responsibility model , exemplified through Microsoft 365's approach, offers a framework for comprehending and implementing effective cybersecurity measures.  The Essence of Shared Responsibility  Think of cloud security like a well-maintained building: the property manager handles structural integrity and common areas, while tenants secure their individual units. Similarly, the shared responsibility model creates a clear division of security duties between cloud providers and their users. This partnership approach ensures comprehensive protection through clearly defined roles and responsibilities.  What Your Cloud Provider Handles  Microsoft maintains comprehensive responsibility for securing the foundational eleme...
