Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR). "This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack

This booklet summarises upcoming challenges and provides for an assessment of the risks. We are now ready to design the cyber secure future ahead of us.

In June 2017, a study of more than 3,000 Massachusetts Institute of Technology (MIT) students published by the National Bureau for Economic Research (NBER) found that 98% of them were willing to give away their friends' email addresses in exchange for free pizza. "Whereas people say they care about privacy, they are willing to relinquish private data quite easily when

Posted by Sarah Jacobus, Vulnerability Rewards Team Last year, we again witnessed the power of community-driven security efforts as researchers from around the world contributed to help us identify and address thousands of vulnerabilities in our products and services. Working with our dedicated bug hunter community, we awarded $10 million to our 600+ researchers based in 68 countries. New Resources and Improvements Just like every year, 2023 brought a series of changes and improvements to our vulnerability reward programs: Through our new Bonus Awards program, we now periodically offer time-limited, extra rewards for reports to specific VRP targets. We expanded our exploit reward program to Chrome and Cloud through the launch of v8CTF, a CTF focused on V8, the JavaScript engine that powers Chrome. We launched Mobile VRP which focuses…

Indian government entities and energy companies have been targeted by unknown threat actors with an aim to deliver a modified version of an open-source information stealer malware called HackBrowserData and exfiltrate sensitive information in some cases by using Slack as command-and-control (C2). "The information stealer was delivered via a phishing email, masquerading as an invitation letter

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has added a security flaw impacting the Microsoft Sharepoint Server to its Known Exploited Vulnerabilities (KEV) catalog based on evidence of active exploitation in the wild. The vulnerability, tracked as CVE-2023-24955 (CVSS score: 7.2), is a critical remote code execution flaw that allows an authenticated attacker with

A now-patched security flaw in the Microsoft Edge web browser could have been abused to install arbitrary extensions on users' systems and carry out malicious actions.  "This flaw could have allowed an attacker to exploit a private API, initially intended for marketing purposes, to covertly install additional browser extensions with broad permissions without the user's knowledge," Guardio
