Serious Bug Exposes Sensitive Data From Millions Sites Sitting Behind CloudFlare

Serious Bug Exposes Sensitive Data From Millions Sites Sitting Behind CloudFlare

Feb 24, 2017
A severe security vulnerability has been discovered in the CloudFlare content delivery network that has caused big-name websites to expose private session keys and other sensitive data. CloudFlare, a content delivery network (CDN) and web security provider that helps optimize safety and performance of over 5.5 Million websites on the Internet, is warning its customers of the critical bug that could have exposed a range of sensitive information, including passwords, and cookies and tokens used to authenticate users. Dubbed Cloudbleed , the nasty flaw is named after the Heartbleed bug that was discovered in 2014, but believed to be worse than Heartbleed. The vulnerability is so severe that it not only affects websites on the CloudFlare network but affects mobile apps as well. What exactly is "Cloudbleed," how it works, how are you affected by this bug, and how you can protect yourself? Let's figure it out. What is Cloudbleed? Discovered by Google Project Ze

Project Zero - A Team of Star-Hackers Hired by Google to Protect the Internet

Jul 15, 2014
Today Google has publicly revealed its new initiative called " Project Zero, " a team of Star Hackers and Bug Hunters with the sole mission to improve security and protect the Internet. A team of superheroes in sci-fi movies protect the world from Alien attack or bad actors, likewise  Project Zero is a dedicated team of top security researchers, who have been hired by Google to finding the most severe security flaws in software around the world and fixing them. PROTECT ZERO vs ZERO-DAY Project Zero gets its name from the term " zero-day ," and team will make sure that zero-day vulnerabilities don't let fall into the wrong hands of Criminals, State-sponsored hackers and Intelligence Agencies. " Yet in sophisticated attacks, we see the use of "zero-day" vulnerabilities to target, for example, human rights activists or to conduct industrial espionage. " Chris Evans said , who was leading Google's Chrome security team and now will lead Pro
Making Sense of Operational Technology Attacks: The Past, Present, and Future

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Internet Explorer vulnerability exposed by Google Researcher used in targeted attacks

Jul 11, 2013
Google and Microsoft are at each other's throats again. In a recent statement, Microsoft says hackers have been actively exploiting a vulnerability that was publicly disclosed by a Google researcher,  Tavis Ormandy . Microsoft addressed the vulnerability in its monthly " Patch Tuesday " package of fixes for July. Tavis Ormandy revealed the vulnerability in Windows 7 and 8 allows local users to obtain escalated privileges , making it easier for a hacker to compromise a system. Ormandy has been criticized by Microsoft and some in the security community who subscribe to the practice that a vulnerability shouldn't be made public until a software maker has an opportunity to fix it. Ormandy said that Microsoft " treat vulnerability researchers with great hostility " and are " often very difficult to work with ". He also advised researchers to use pseudonyms when dealing with the software giants. In 2012, Tavis accused Sophos of " poor development practices
