Russia's communications regulator Roskomnadzor has threatened Apple to face the consequences if the company does not remove secure messaging app Telegram from its App Store. Back in April, the Russian government banned Telegram in the country for the company's refusal to hand over private encryption keys to Russian state security services to access messages sent using the secure service. However, so far, the Telegram app is still available in the Russian version of Apple's App Store. So in an effort to entirely ban Telegram, state watchdog Roskomnadzor reportedly sent a legally binding letter to Apple asking it to remove the app from its Russian App Store and block it from sending push notifications to local users who have already downloaded the app. Roskomnadzor's director Alexander Zharov said he is giving the company one month to remove the Telegram app from its App Store before the regulator enforces punishment for violations. For those unfamiliar with...

A 23-year-old Canadian man, who pleaded guilty last year for his role in helping Russian government spies hack into email accounts of Yahoo users and other services, has been sentenced to five years in prison. Karim Baratov (a.k.a Karim Taloverov, a.k.a Karim Akehmet Tokbergenov), a Kazakhstan-born Canadian citizen, was also ordered on Tuesday by United States Judge Vince Chhabria to pay a fine of $250,000. Baratov had previously admitted his role in the 2014 Yahoo data breach that compromised about 500 million Yahoo user accounts. His role was to "hack webmail accounts of individuals of interest to the FSB," Russia's spy agency. In November, Baratov pleaded guilty to a total of nine counts, including one count of conspiring to violate the Computer Fraud and Abuse Act, and eight counts of aggravated identity theft. According to the US Justice Department, Baratov and his co-defendant hacker Alexsey Belan worked for two agents—Dmitry Dokuchaev and Igor Sushch...

Security researchers have discovered a series of new vulnerabilities in EOS blockchain platform, one of which could allow remote hackers to take complete control over the node servers running the critical blockchain-based applications. EOS is an open source smart contract platform, known as 'Blockchain 3.0,' that allows developers to build decentralized applications over blockchain infrastructure, just like Ethereum. Discovered by Chinese security researchers at Qihoo 360 —Yuki Chen of Vulcan team and Zhiniang Peng of Core security team—the vulnerability is a buffer out-of-bounds write issue which resides in the function used by nodes server to parse contracts. To achieve remote code execution on a targeted node, all an attacker needs to do is upload a maliciously crafted WASM file (a smart contract) written in WebAssembly to the server. As soon as the vulnerable process parser reads the WASM file, the malicious payload gets executed on the node, which could then al...

German security researchers claim to have found a new practical attack against virtual machines (VMs) protected using AMD's Secure Encrypted Virtualization (SEV) technology that could allow attackers to recover plaintext memory data from guest VMs. AMD's Secure Encrypted Virtualization (SEV) technology, which comes with EPYC line of processors, is a hardware feature that encrypts the memory of each VM in a way that only the guest itself can access the data, protecting it from other VMs/containers and even from an untrusted hypervisor. Discovered by researchers from the Fraunhofer Institute for Applied and Integrated Security in Munich, the page-fault side channel attack, dubbed SEVered, takes advantage of lack in the integrity protection of the page-wise encryption of the main memory, allowing a malicious hypervisor to extract the full content of the main memory in plaintext from SEV-encrypted VMs. Here's the outline of the SEVered attack, as briefed in the paper :...

Researchers have found that even after having an advanced encryption scheme in place, more than 100 million Internet-of-Things (IoT) devices from thousands of vendors are vulnerable to a downgrade attack that could allow attackers to gain unauthorized access to your devices. The issue resides in the implementation of Z-Wave protocol —a wireless, radio frequency (RF) based communications technology that is primarily being used by home automation devices to communicate with each other. Z-Wave protocol has been designed to offer an easy process to set up pairing and remotely control appliances—such as lighting control, security systems, thermostats, windows, locks, swimming pools and garage door openers—over a distance of up to 100 meters (330 feet). The latest security standard for Z-Wave, called S2 security framework, uses an advanced key exchange mechanism, i.e., Elliptic-Curve Diffie-Hellman (ECDH) anonymous key agreement protocol, to share unique network keys between the con...

Pornhub wants you to keep your porn viewing activities private, and it is ready to help you out with its all-new safety and privacy free VPN service. Yes, you heard that right. Adult entertainment giant Pornhub that allows porn videos download has launched its very own free VPN service today with "unlimited bandwidth" to help you keep prying eyes away from your browsing activity.
