If you think that the HTTP/2 protocol is more secure than the standard HTTP ( Hypertext Transfer Protocol ), then you might be wrong, as it took researchers just four months to discover four flaws in the HTTP/2 protocol. HTTP/2 was launched properly just in May last year after Google bundled its SPDY project into HTTP/2 in February in an effort to speed up the loading of web pages as well as the browsing experience of the online users. Now, security researchers from data center security vendor Imperva today at Black Hat conference revealed details on at least four high-profile vulnerabilities in HTTP/2 – a major revision of the HTTP network protocol that the today's web is based on. The vulnerabilities allow attackers to slow web servers by flooding them with innocent looking messages that carry a payload of gigabytes of data, putting the servers into infinite loops and even causing them to crash. The HTTP/2 protocol can be divided into three layers: The transmissio...

Yet another blow to Bitcoin: One of the world's most popular exchanges of the cryptocurrency has suffered a major hack, leading to a loss of around $72 Million worth of Bitcoins. Hong Kong-based Bitcoin exchange ' Bitfinex ' has posted a note on their website announcing the shutdown of its operation after discovering a security breach that allowed an attacker to steal some user funds. While the company did not mention a total amount lost in the breach, one of their employees — Bitfinex community director Zane Tackett — confirmed on Reddit that the total amount stolen was 119,756 bitcoins — worth up to $72 Million in cash. The cause of the security breach and the hacker behind the incident is still unclear, but the attackers appear to have mysteriously bypassed Bitfinex's mandated limits on withdrawals. "The theft is being reported to — and we are co-operating with — law enforcement," Bitfinex statement reads. "We will look at various options to ...

We have heard a lot about data breaches nowadays. And if you think that switching to an encrypted messaging service may secure you and your data, then you may be wrong. No good deed today can help you protect yourself completely. Reuters and several media outlets are reporting that the phone numbers of 15 Million users in Iran and more than a dozen accounts on the Telegram instant messaging service have been compromised by Iranian hackers exploiting an SMS text message flaw. Telegram is a messaging app " with a focus on security " that promotes itself as an ultra secure instant messaging system as all data is end-to-end encrypted. The service claims to have 100 Million active subscribers. According to research conducted by two security researchers, Collin Anderson and Claudio Guarnieri, this attack has threatened the communications of activists, journalists and other people in Iran, where around 20 Million people use Telegram. The incident is even said to be the...

Is my smartphone battery leaking details about me? Unfortunately, YES! Forget about supercookies, apps, and malware; your smartphone battery status is enough to monitor your online activity, according to a new report. In 2015, researchers from Stanford University demonstrated a way to track users' locations – with up to 90 percent accuracy – by measuring the battery usage of the phone over a certain time. The latest threat is much worse. Two security researchers, Steve Engelhard and Arvind Narayanan, from Princeton University, have published a paper describing how phone's battery status has already been used to track users across different websites. The issue is due to the Battery Status API (application programming interface). How Does Battery Status API Help Advertisers Track You? The battery status API was first introduced in HTML5 and had already shipped in browsers including Firefox, Chrome, and Opera by August last year. The API is intended to allo...

Google has rolled out a new feature for Android users to keep its users account more secure: Native Android Push Notification when a new device accesses your Google account. Google has already been offering email notification for newly added devices, but since people usually ignore emails, the tech giant will now send a push notification to your device screen, giving you a chance to change your password immediately before an intruder gets in. Although it's a little change, the company believes people pay four times more attention on push notifications on their devices compared to email notification. The new feature " increases transparency to the user of what actions they've performed and allows them to flag any suspicious activity they may be seeing on the device, " the company says in its official blog post . So, from now on, when a new device is added to your Google account, or, in other words, when a new device accesses your account, you will receive a ...
