If your mobile carrier offers LTE, also known as the 4G network, you need to beware as your network communication can be hijacked remotely. A team of researchers has discovered some critical weaknesses in the ubiquitous LTE mobile device standard that could allow sophisticated hackers to spy on users' cellular networks, modify the contents of their communications, and even can re-route them to malicious or phishing websites. LTE, or Long Term Evolution, is the latest mobile telephony standard used by billions of people designed to bring many security improvements over the predecessor standard known as Global System for Mobile (GSM) communications. However, multiple security flaws have been discovered over the past few years, allowing attackers to intercept user's communications, spy on user phone calls and text messages, send fake emergency alerts, spoof location of the device and knock devices entirely offline. 4G LTE Network Vulnerabilities Now, security researchers

In Brief The famous '60 Minutes' television show shocked some viewers Sunday evening when a team of German hackers demonstrated how they spied on an iPhone used by U.S. Congressman, then recorded his phone calls and tracked his movement through Los Angeles. Hackers leverage a security flaw in SS7 (Signalling System Seven) protocol that allows hackers to track phone locations, listen in on calls and text messages. The global telecom network SS7 is still vulnerable to several security flaws that could let hackers and spy agencies listen to personal phone calls and intercept SMSes on a potentially massive scale, despite the most advanced encryption used by cellular networks. All one need is the target's phone number to track him/her anywhere on the planet and even eavesdrop on the conversations. SS7 or Signalling System Number 7 is a telephony signaling protocol used by more than 800 telecommunication operators around the world to exchange information with one

Shadow apps, a segment of Shadow IT, are SaaS applications purchased without the knowledge of the security team. While these applications may be legitimate, they operate within the blind spots of the corporate security team and expose the company to attackers.  Shadow apps may include instances of software that the company is already using. For example, a dev team may onboard their own instance of GitHub to keep their work separate from other developers. They might justify the purchase by noting that GitHub is an approved application, as it is already in use by other teams. However, since the new instance is used outside of the security team's view, it lacks governance. It may store sensitive corporate data and not have essential protections like MFA enabled, SSO enforced, or it could suffer from weak access controls. These misconfigurations can easily lead to risks like stolen source code and other issues. Types of Shadow Apps  Shadow apps can be categorized based on their interac

Wanna Hack an extremely secure Computer? You do not need sophisticated techniques or equipment to do so. To hack an Air-Gapped computer – All you need is a cell phone; even old-fashioned, dumb phones from the past decade will work. Yes, Hacking Air-Gapped Computers is possible using a basic low-end mobile phone. Israeli security researchers have devised a new attack to steal data from a computer that is isolated from the internet and other computers that are connected to external networks, also known as an air-gapped computer. This new hack attack that could steal data from a highly secured computer uses: The GSM network Electromagnetic waves A basic low-end mobile phone The research was conducted by lead security researcher Mordechai Guri, along with Yuval Elovici, Assaf Kachlon, Ofer Hasson, Yisroel Mirsky, and Gabi Kedma – the same researchers who developed a previous attack that used a smartphone to wirelessly extract data from Air-Gapped computers .
