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...

British police have arrested a suspect in connection with the massive attack on Deutsche Telekom that hit nearly 1 Million routers last November. Late last year, someone knocked down more than 900,000 broadband routers belonging to Deutsche Telekom users in Germany, which affected the telephony, television, and internet service in the country. Now, Germany's federal criminal police force (BKA) revealed today that the UK's National Crime Agency (NCA) reportedly arrested a 29-year-old British suspect at Luton airport in London on Wednesday, who is accused of being the mastermind behind the last year's attack. In a statement , the German police said the last year's attack was especially severe and was carried out to compromise the home routers to enroll them in a network of hijacked machines popularly known as Botnet, and then offer the DDoS services for sale on dark web markets. But ultimately, the attack created a denial-of-service situation, which resulted i...

SHA-1, Secure Hash Algorithm 1, a very popular cryptographic hashing function designed in 1995 by the NSA, is officially dead after a team of researchers from Google and the CWI Institute in Amsterdam announced today submitted the first ever successful SHA-1 collision attack. SHA-1 was designed in 1995 by the National Security Agency (NSA) as a part of the Digital Signature Algorithm. Like other hashes, SHA-1 also converts any input message to a long string of numbers and letters that serve as a cryptographic fingerprint for that particular message. Collision attacks appear when the same hash value (fingerprint) is produced for two different messages, which then can be exploited to forge digital signatures, allowing attackers to break communications encoded with SHA-1. The explanation is technologically tricky, but you can think of it as attackers who surgically alters their fingerprints in order to match yours, and then uses that to unlock your smartphone. The researchers h...

Another privilege-escalation vulnerability has been discovered in Linux kernel that dates back to 2005 and affects major distro of the Linux operating system, including Redhat, Debian, OpenSUSE, and Ubuntu. Over a decade old Linux Kernel bug ( CVE-2017-6074 ) has been discovered by security researcher Andrey Konovalov in the DCCP (Datagram Congestion Control Protocol) implementation using Syzkaller , a kernel fuzzing tool released by Google. The vulnerability is a use-after-free flaw in the way the Linux kernel's "DCCP protocol implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket." The DCCP double-free vulnerability could allow a local unprivileged user to alter the Linux kernel memory, enabling them to cause a denial of service ( system crash ) or escalate privileges to gain administrative access on a system. "An attacker can control what object that would be and overwrite...

Next time when you accidentally or curiously land up on a website with jumbled content prompting you to download a missing font to read the blog by updating the Chrome font pack… …Just Don't Download and Install It. It's a Trap! Scammers and hackers are targeting Google Chrome users with this new hacking scam that's incredibly easy to fall for, prompting users to download a fake Google Chrome font pack update just to trick them into installing malware on their systems. Here's What the Scam is and How it works: It's a "The 'HoeflerText' font wasn't found" scam. Security firm NeoSmart Technologies recently identified the malicious campaign while browsing an unnamed WordPress website that had allegedly already been compromised, possibly due to failing to apply timely security updates. The scam is not a new one to identified by NeoSmart. It has been making rounds since last month . The hackers are inserting JavaScript into poorl...
