Today's enterprise networks are complex environments with different types of wired and wireless devices being connected and disconnected. The current device discovery solutions have been mainly focused on identifying and monitoring servers, workstation PCs, laptops and infrastructure devices such as network firewalls, switches and routers, because the most valuable information assets of organizations are being stored, processed and transferred over those devices, hence making them the prime target of security breaches and intrusions. However, a new trend has been emerging in the past four years,  where attackers have been targeting purpose-built connected devices  such as network printers and video conferencing systems as an entry point and data exfiltration route. These devices cannot be identified properly by the current IT asset discovery solutions for the following main reasons: Proprietary protocols are often used for managing and monitoring such devices that are not know

A team of researchers from the University of Michigan discovered that hundreds of applications in Google Play Store have a security hole that could potentially allow hackers to steal data from and even implant malware on millions of Android smartphones. The University of Michigan team says that the actual issue lies within apps that create open ports — a known problem with computers — on smartphones. So, this issue has nothing to do with your device's operating system or the handset; instead, the origin of this so-called backdoor is due to insecure coding practices by various app developers. The team used its custom tool to scan over 100,000 Android applications and found 410 potentially vulnerable applications — many of which have been downloaded between 10 and 50 Million times and at least one app comes pre-installed on Android smartphones. Here I need you to stop and first let's understand exactly what ports do and what are the related threats. Ports can be eit

Have you ever used Shodan search engine? A publicly available service crawls the Internet looking for connected devices and list their open ports, services running, system information etc. Shodan search engine is majorly used by Hackers, developers, students and anyone else with a sense of curiosity to find Internet-facing vulnerable systems with open ports and insecure mechanisms for authentication and authorization i.e. Servers, Internet-Connected Cameras, Traffic Lights, And SCADA Systems. According to latest revelation from the whistleblower Edward Snowden , British spy agency GCHQ – counterpart of NSA – apparently uses their own port scanning service to target internet-connected systems in at least 27 countries, in an attempt to potentially exploit them. In top-secret documents published by Heise on Friday, the Port-scan is a part of the "Hacienda" program which scans for open ports on all public-facing servers to find out vulnerable applications running on the

There's a natural human desire to avoid threatening scenarios. The irony, of course, is if you hope to attain any semblance of security, you've got to remain prepared to confront those very same threats. As a decision-maker for your organization, you know this well. But no matter how many experts or trusted cybersecurity tools your organization has a standing guard, you're only as secure as your weakest link. There's still one group that can inadvertently open the gates to unwanted threat actors—your own people. Security must be second nature for your first line of defense For your organization to thrive, you need capable employees. After all, they're your source for great ideas, innovation, and ingenuity. However, they're also human. And humans are fallible. Hackers understand no one is perfect, and that's precisely what they seek to exploit. This is why your people must become your first line of defense against cyber threats. But to do so, they need to learn how to defend thems

In October, A Security researcher ' Craig Heffner ' discovered a backdoor vulnerability ( CVE-2013-6027 ) with certain D-Link routers that allow cyber criminals to alter a router setting without a username or password. Last week, D-Link has released new version of Firmware for various vulnerable router models, that patches the unauthorized administrator access backdoor. Heffner  found that the web interface for some D-Link routers could be accessed if the browser's user agent string is set to xmlset_roodkcableoj28840ybtide . From last month, D-Link was working with Heffner and other security researchers, to find out more about the backdoor and now the Company has released the updates for the following models: DIR-100 DIR-120 DI-524 DI-524UP DI-604UP DI-604+ DI-624S TM-G5240 The company advised users to do not enable the Remote Management feature, since this will allow malicious users to use this exploit from the internet and also warned t

Most of you knows the power of Nmap, When used properly, Nmap helps protect your network from invaders. One of the best tool for hackers, penetration testers and Security  researchers. Officially Nmap a desktop tool, can be used as web version but should be under some limitations. When someone does Nmap scan against a target to find out the open ports, enumerating system details and installed services versions, most obvious if  used improperly, Nmap can get you sued, fired, expelled, jailed, or banned by your ISP for scanning a target under hacking attempt. Hacker can be tracked back via the IP address from where one perform the scanning, but what if a web version of Nmap available on a website, where one just need to enter the target IP/website address and that website will do a free scan against your target ? Seems easy and one can use Proxy to access that website and which will do a simple and fast scan for you ! Yes, a service called " ScanPlanner " (htt

After five months NMAP team release latest version of open source utility for network exploration or security auditing - NMAP 6.25 . It was designed to rapidly scan large networks, but works fine against single hosts. Nmap runs on all major computer operating systems, and official binary packages are available for Linux, Windows, and Mac OS X. Many systems and network administrators also find it useful for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics. Updates: integration of over 3,000 IPv4 new OS fingerprint submissions, over 1,500 service/version detection fingerprints, and of the latest IPv6 OS submissio
