Malicious COVID-19 online content - including racist content, disinformation and misinformation - thrives and spreads online by bypassing the moderation efforts of individual social media platforms. By mapping online hate clusters across six major social media platforms, researchers at the George Washington University show how malicious content exploits pathways between platforms, highlighting the need for social media companies to rethink and adjust their content moderation policies.

As the list of known organizations compromised by way of the SolarWinds supply chain attack is slowly growing - according to Reuters, the attackers also breached U.S. Department of Homeland Security's systems, the State Department, and the National Institutes of Health - Microsoft has decided that its Defender Antivirus will start blocking/quarantining the known malicious SolarWinds binaries today - even if the process is running. As security researcher Vinoth Kumar pointed out, the attackers might have easily compromised the company's update server by using a password that was published on their public Github repository for over a year or, as several Reuters sources noted, they might have bought access to SolarWinds' computers through underground forums.
Researchers with ETH Zurich have identified vulnerabilities in the implementation of the payment card EMV standard that allow for the mounting of attacks targeting both the cardholder and the merchant. In a newly published paper, David Basin, Ralf Sasse, and Jorge Toro-Pozo from the department of computer science at ETH Zurich, explain that vulnerabilities identified in the standard EMV implementation could be exploited to render the PIN verification useless on Visa contactless transactions.
Mozilla announced on Thursday that it has expanded its bug bounty program with a new category that focuses on bypass methods for the exploit mitigations, security features and defense-in-depth measures in Firefox.
