If you came across any Facebook Message with an image file (exactly .SVG file format) send by any of your Facebook friends, just avoid clicking it. An ongoing Facebook spam campaign is spreading malware downloader among Facebook users by taking advantage of innocent-looking SVG image file to infect computers. If clicked, the file would eventually infect your PC with the nasty Locky Ransomware , a family of malware that has quickly become one of the favorite tools among criminals due to its infecting capabilities. Discovered by malware researcher Bart Blaze , the attack campaign uses Facebook Messenger to spread a malware downloader called Nemucod that takes the form of .SVG image files. Why SVG file? Hackers considered SVG (or Scalable Vector Graphics) files for spreading the malware downloader, because SVG has the ability to contain embedded content such as JavaScript, and can be opened in a modern web browser. Crooks added their malicious JavaScript code right inside th

Here's some bad news for Android users again. Nearly 3 Million Android devices worldwide are vulnerable to man-in-the-middle (MITM) attacks that could allow attackers to remotely execute arbitrary code with root privileges, turning over full control of the devices to hackers. According to a new report from security rating firm BitSight, the issue is due to a vulnerability in the insecure implementation of the OTA (Over-the-Air) update mechanism used by certain low-cost Android devices, including BLU Studio G from US-based Best Buy. Backdoor/Rootkit Comes Pre-installed The vulnerable OTA mechanism, which is associated with Chinese mobile firm Ragentek Group, contains a hidden binary — resides as /system/bin/debugs — that runs with root privileges and communicates over unencrypted channels with three hosts. According to the researchers, this privileged binary not only exposes user-specific information to MITM attackers but also acts as a rootkit, potentially allowing

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

Big tech companies, including Facebook, Google, and Microsoft, are in the race of bringing Internet connectivity to unconnected parts of the world through wireless devices , flying drones , high-altitude balloons, and laser beams . But, SpaceX founder Elon Musk has big plans for bringing low-cost Internet service worldwide, and it all starts in space. Private rocket launch service SpaceX has asked the U.S. government for permission to launch 4,425 satellites in orbit to beam high-speed Internet down to the world, according to a newly filed application with the Federal Communications Commission (FCC). That's a hell of a lot of satellites; in fact, the figure surpasses the total number of satellites in the Earth's orbit. Here's what the company's 102-page technical document reads: "The system is designed to provide a wide range of broadband and communications services for residential, commercial, institutional, governmental and professional users world

Three, one of UK's biggest mobile operators, has become the latest victim of a massive data breach that reportedly left the personal information and contact details of 6 Million of its customers exposed. The company admitted the data breach late Thursday, saying that computer hackers gained access to a Three Mobile customer phone upgrade database containing the account details of nearly 6 Million customers. According to multiple British  media reports citing both Three and the National Crime Agency ( NCA ), the computer hackers used an employee login to gain entry into its database. The stolen data includes customer names, addresses, phone numbers and dates of birth, which is then used to carry out mobile phone fraud. The company has not yet confirmed the total number of users' affected by the breach, though it assured its customers that no payment data, including bank account numbers and card numbers, has been accessed. According to Three, the hackers had stolen

In the fight against encryption , Apple has positioned itself as a staunch defender of its user privacy by refusing the federal officials to provide encryption backdoors into its products, as well as implementing better encryption for its products. However, a new report from a security firm suggests Apple's online syncing service iCloud secretly stores logs of its users' private information for as long as four months — even when iCloud backup is switched off. Russian digital forensics firm Elcomsoft discovered that Apple's mobile devices automatically send its users' call history to the company's servers if iCloud is enabled, and stored that data for up to four months. And it turns out that there is no way for iCloud users to stop this phone call syncing service unless they completely disable the cloud synchronization feature. Elcomsoft, which sells software to extract data from Apple's iCloud backups and works with police and intelligence agencies,
