At BestCybersecurityNews, we help entrepreneurs, solopreneurs, young learners, and seniors learn more about cybersecurity.
Rogue access points (also referred to as evil twins) are wireless networks installed by attackers within or near an organization to bypass security controls and intercept data. Hackers or authorized users could install them themselves.
To prevent unwelcome access points from popping up within your facilities, regular scans using wireless sniffing tools should be conducted and policies put into effect to deter employees from installing access points themselves.

What is a Rogue Access Point and How Can it Impact Cybersecurity?
Rogue access points are unintentionally placed wireless devices on networks, which allow hackers to gain entry and access to sensitive data. Rogue access points also serve as wireless backdoors into networks by bypassing network firewalls and security devices.
Rogue access points continue to present an ever-increasing threat, as hackers increasingly leverage this tool for attacks. Therefore, it’s vital that organizations perform regular scans for unauthorized devices within their facilities.
Rogue access points often spring up unwittingly – an employee might use their iPad or home laptop on the corporate Wi-Fi network because of slow speeds – while others can be installed intentionally by hackers looking to conduct man-in-the-middle attacks or sniff traffic and distribute malware through these rogue access points.
Healthcare facilities face unique cybersecurity challenges. In an industry that performs lifesaving operations, patient safety takes precedence over cyber hygiene for many employees; thus leaving rogue access points often unnoticed or difficult to detect by staff; due to being able to spoof legitimate AP’s MAC address they can often be mistaken as legitimate ones by staff members.
Due to HDOs’ expansive facilities, providing coverage across all areas can be challenging. Gaps in coverage provide opportunities for malicious access points – known as wireless evil twin attacks – to appear with similar SSID and BSSID configurations as their secure network, yet send stronger signals that attract unsuspecting users by mimicking its signal strength and lure them away from it. This leaves HDO networks vulnerable to attack.
To avoid rogue access points, the best approach is to deploy an IDS/IPS solution that catalogs existing wireless access points within your environment. This may be straightforward if your infrastructure fits neatly within one data center, but it can become more challenging if distributed organizations exist. An additional helpful method would be using a managed switch with port-based security as it prevents anyone from plugging an access point into random unused ports on the network without first blocking it automatically.

Is Passive Interception the Weakest Link in Cybersecurity?
Phantom Technologies GSM passive interception system is an off-the-air (OTA) tactical interception solution specifically tailored for the GSM band that eliminates law enforcement agencies’ need to seek cooperation from unfavorable international government agencies or communication service providers. By employing passive probes for interception purposes instead of alerting their target of an investigation by alerting passive probes for intercept communications without alerting anyone who may have already been compromised during investigations, LEAs can now avoid alerting targets of an investigation – with no electromagnetic signature in the network and quickly deployable fixed installations as well as mobile deployments such as in an SUV if necessary.
Passive interception works by collecting and storing data on the target device before using this data to produce authorized effects, such as denial-of-service attacks, impersonation attempts or manipulating network traffic or files – these effects may then be used for surveillance, criminal investigation or espionage purposes.
As shown in FIG. 3, hybrid interception systems combine passive and active interception strategies. They consist of two interception subsystems working in concert to track target terminals; usually when one detects one, another responds and intercepts target communication.
The method starts with passive interception subsystem 32 detecting a target terminal at step 80 and identifying it through TMSI identification at step 86. Next, active interception subsystem 36 temporarily activates bidirectional communication with it at an active triggering step 88 before extracting IMSIs from that communication session.
At step 92, the active interception subsystem reports any matching TMSIs to monitoring center 52 at the reporting step. In some embodiments, the active interception subsystem may also send matching IMSIs directly to the passive interception subsystem 32 for further action.

Can Rogue Access Points Compromise Cybersecurity?
Active interception differs from passive attacks in that it involves breaking into networks and interfering with data transmissions – for instance by injecting malware or changing content – by hacking into them and altering data transmissions directly. It often causes more noticeable disruption in communication between two parties than passive attacks do due to visible changes or disruptions caused by active intercepts, as attackers use intercepted information for man-in-the-middle attacks to steal sensitive information such as login credentials and financial transactions.
This attack can occur on WiFi networks that do not utilize preventative measures to eliminate rogue access points, or by using devices such as smartphones to create their own APs. Furthermore, such attacks may be used to intercept traffic from wireless clients and send it directly to an external server that has malicious intentions of stealing information – exploitable through various techniques including DNS spoofing, SSL stripping, session hijacking, and phishing attacks.
Rogue access points (APs) can be identified using RTT measurements on wired or guided media and differentiating between regular and wireless LAN connections by distinguishing their timing differences. Unfortunately, this method requires permission from network administrators or infrastructure owners; an energy company recently faced this issue and hired a cybersecurity provider to create a Secure Environment and Procedure (SEP) environment, implement their new infrastructure, and align security policy configuration with best practices.
The result was a cloud-based platform using machine learning to detect known and unknown rogue access points within an enterprise network. Utilizing scanning tools, WiFi protection apps, IDS/IPS services, and client identification programs the platform identified rogue clients that attempted to connect but were prohibited from doing so – as well as providing a centralized view of security policies across workstations and servers.

Malicious Wi-Fi: Is Your Network at Risk?
Malware (malicious software) is a form of cyberattack that allows attackers to gain entry to computers without their users knowing it. Malware can spread via email attachments and links that secretly install it on users’ machines; viruses, worms, Trojans and ransomware are some examples of popular forms of malware that attack computers without users knowing about it; it encrypts files and denies access until victims pay a certain sum to cyber-attackers in exchange for unlocking them again; spyware rootkits and backdoors allow attackers to monitor activity on infected computers as well as remote controlling them from another computer infected with Malware.

Can Unauthorized Access Compromise Cybersecurity?
Unauthorized access refers to any instance in which someone gains uninvited entry to data networks, systems, endpoints, applications and devices without proper permission. It could come about via various methods – hackers using brute force attacks against weak passwords to phishing scams that trick authorized users into revealing credentials – potentially leading to significant financial losses and service disruption for an organization.
Unauthorized access detection and prevention are crucial elements in protecting your business against its destructive potential. The sooner an incident is discovered, the sooner you can respond and put a stop to any fraudulent activities within your system. There are numerous methods of detecting unauthorized access – physical entry points to network devices running rogue software can all serve as points of intrusion – from physical locks on doors and gates through to software glitches that provide illegal entry points into buildings.
One of the most prevalent forms of unauthorized access is tailgating, in which an individual follows an authorized person into a secure area without providing credentials. This can happen due to either succumbing to polite pressure and holding open the door for them out of politeness, or when deliberately bypassing security measures such as turnstiles and mantraps. Collusion, on the other hand, involves people purposely bypassing security measures for someone else’s benefit.
Unauthorized access can also be achieved by exploiting existing vulnerabilities. This could range from simple password guessing attacks, all the way up to comprehensive cyberattacks that take weeks of planning and implementation. Even when attackers do not succeed in stealing anything themselves, unauthorised access still has serious repercussions; cybercriminals could disrupt electronic systems or cause them to crash – either to gain an edge in competition, harm your business, or simply be annoying.
