This Unpatchable Flaw Affects All Intel CPUs Released in Last 5 Years

This Unpatchable Flaw Affects All Intel CPUs Released in Last 5 Years

March 06, 2020Wang Wei
All Intel processors released in the past 5 years contain an unpatchable vulnerability that could allow hackers to compromise almost every hardware-enabled security technology that are otherwise designed to shield sensitive data of users even when a system gets compromised. The vulnerability, tracked as CVE-2019-0090 , resides in the hard-coded firmware running on the ROM ("read-only memory") of the Intel's Converged Security and Management Engine (CSME), which can't be patched without replacing the silicon. Intel CSME is a separate security micro-controller incorporated into the processors that provides an isolated execution environment protected from the host opening system running on the main CPU. It is responsible for the initial authentication of Intel-based systems by loading and verifying firmware components, root of trust based secure boot, and also cryptographically authenticates the BIOS, Microsoft System Guard, BitLocker, and other security features
Researchers Find New Hack to Read Content Of Password Protected PDF Files

Researchers Find New Hack to Read Content Of Password Protected PDF Files

October 01, 2019Mohit Kumar
Looking for ways to unlock and read the content of an encrypted PDF without knowing the password? Well, that's now possible, sort of—thanks to a novel set of attacking techniques that could allow attackers to access the entire content of a password-protected or encrypted PDF file, but under some specific circumstances. Dubbed PDFex , the new set of techniques includes two classes of attacks that take advantage of security weaknesses in the standard encryption protection built into the Portable Document Format, better known as PDF. To be noted, the PDFex attacks don't allow an attacker to know or remove the password for an encrypted PDF; instead, enable attackers to remotely exfiltrate content once a legitimate user opens that document. In other words, PDFex allows attackers to modify a protected PDF document, without having the corresponding password, in a way that when opened by someone with the right password, the file will automatically send out a copy of the decry
Google Created Faster Storage Encryption for All Low-End Devices

Google Created Faster Storage Encryption for All Low-End Devices

February 08, 2019Swati Khandelwal
Google has launched a new encryption algorithm that has been built specifically to run on mobile phones and smart IoT devices that don't have the specialized hardware to use current encryption methods to encrypt locally stored data efficiently. Encryption has already become an integral part of our everyday digital activities. However, it has long been known that encryption is expensive, as it causes performance issues, especially for low-end devices that don't have hardware support for making the encryption and decryption process faster. Since data security concerns have recently become very important, not using encryption is no more a wise tradeoff, and at the same time, using a secure but slow device on which apps take much longer to launch is also not a great idea. Currently Android OS supports AES-128-CBC-ESSIV for full-disk encryption and AES-256-XTS for file-based encryption, and Google has already made it mandatory for device manufacturers to include AES encry
Australia Passes Anti-Encryption Bill—Here's Everything You Need To Know

Australia Passes Anti-Encryption Bill—Here's Everything You Need To Know

December 07, 2018Swati Khandelwal
Australia's House of Representatives has finally passed the "Telecommunications Assistance and Access Bill 2018," also known as the Anti-Encryption Bill , on Thursday that would now allow law enforcement to force Google, Facebook, WhatsApp, Signal, and other tech giants to help them access encrypted communications. The Australian government argues the new legislation is important for national security and an essential tool to help law enforcement and security agencies fight serious offenses such as crime, terrorist attacks, drug trafficking, smuggling, and sexual exploitation of children. Since the bill had support from both major parties (the Coalition and Labor), the upper house could vote in support of the Assistance and Access Bill to make it law, which is expected to come into effect immediately during the next session of parliament in early 2019. Although the new legislation does not properly clarify specifics around the potential power that the Assistance
Signal Secure Messaging App Now Encrypts Sender's Identity As Well

Signal Secure Messaging App Now Encrypts Sender's Identity As Well

October 30, 2018Swati Khandelwal
Signal, the popular end-to-end encrypted messaging app, is planning to roll out a new feature that aims to hide the sender's identity from potential attackers trying to intercept the communication. Although messages send via secure messaging services, like Signal , WhatsApp , and Telegram , are fully end-to-end encrypted as they transmit across their servers, each message leaves behind some of the metadata information that reveals who sent the message to whom and when. The new feature, dubbed " Sealed Sender ," announced by Signal is going to further reduce the amount of information that is accessible to the company itself. However, you should note that Signal never stores metadata or logs of information on its users like who sends messages to each other and when, but the new feature would protect the sender's identity in case the communication is somehow intercepted. How Does the Signal's Sealed Sender Feature Protect Metadata? According to a blog post
