Don’t be a victim of VoIP eavesdropping

In the digital world, eavesdropping is a form of cyberattack in which hackers intercept and record Voice over Internet Protocol (VoIP) phone calls, usually to steal personal or business information. Since the attack does not affect call quality, it’s hard to tell if you are being spied on. Implementing these security strategies will help safeguard you from this type of attack.

Change the default configurations of your VoIP system

Using your VoIP phones without changing the default configurations can be the worst mistake you can make. These days, it’s easy for hackers to search vendor documentation for things like default usernames and passwords. Depending on your VoIP provider and phone model, you should have the option of changing the default login credentials on your handsets.

Get updates from your handset vendor

In 2015, Cisco detected vulnerabilities in their VoIP phones that enabled attackers to listen in on phone conversations. Cisco quickly released security alerts to inform their customers about these vulnerabilities, giving them enough time to address the issues. The lesson here is you must regularly monitor advisories from your hardware vendor or work with an IT provider that does so for you. Without proper monitoring, you won’t know how susceptible your corporate VoIP phones are to eavesdropping.

Update session border controllers

Another way to combat VoIP eavesdropping is to constantly update your session border controllers (SBCs). By doing so, you’ll be updating your VoIP’s antivirus software, which means your systems are better protected from constantly evolving cyberthreats. Routine SBC updates are essential for securing SIP trunking as well as responding to new threats.

Encrypt VoIP calls

If you work in a regulated industry like healthcare or finance, encrypting VoIP calls is essential to staying compliant. Work with your VoIP provider and auditors to determine the best encryption options for your communications infrastructure. Many cloud VoIP providers offer call encryption guidelines, and some even offer it as a premium service.

Build a hardened VoIP network

Make sure your VoIP network has:

  • IP private branch exchange (PBX) using minimal services, so that the hardware can only power the PBX software
  • Firewalls with access control lists set to include call control information
  • Lightweight Directory Access Protocol lookup, and signaling and management protocol
  • Reinforced endpoint security with authentication at the endpoint level

To effectively defend against VoIP eavesdropping, businesses need to take a holistic approach to cybersecurity. This includes enforcing policies, deployment, and security practices that will keep malicious agents out of your network.

How to rid your Android devices of malware

As much as Google tries to keep their products safe and secure, they’re not immune to malware. If a malicious software infiltrates your Android operating system, it can compromise the sensitive information contained in your device. Here are a few tips on how to detect and remove malware from your Android device.

Confirm the malware infection

Android devices usually exhibit strange behavior when they’re infected with malware. Their speed may suddenly slow to a crawl or the battery may drain faster than expected. Other telltale signs include an abundance of pop-up ads, unusual apps installed on your home screen, unexplained data usage, and unauthorized in-app purchases.

However, it’s not always easy to tell if your device has been compromised since hackers are becoming more proficient at concealing their actions. The best way to check for malware is to run an antivirus scan using a mobile security solution.

How to get rid of malware

If your device is infected with malware, the most important thing to do is quarantine the threat as soon as possible. Start by rebooting your device in safe mode, which can be selected when you hold down the power button. Not all versions of Android are the same though, so if this isn’t an option, try restarting your device and holding the volume-down button when the manufacturer’s logo appears.

Once you’ve entered safe mode, go to Settings, then Apps, and uninstall any suspicious apps. Do a quick Google search or ask your cybersecurity technician to help you determine whether or not an app is dangerous.

If you can’t uninstall the software, it may have administrative privileges. To fix this, open the Advanced settings menu from the Settings app, then select Security, then Device administrators, remove any app that shouldn’t have privileged access, and return to the Apps menu to uninstall it. Mobile security software should also be able to remove hidden malicious programs in your device.

If the malware persists, you’ll have to do a factory reset. This option is usually located in the Backup & reset configurations within the Advanced settings menu. Keep in mind that you’ll lose the apps and files stored in your device, so it’s important to back up your data beforehand.

Protecting your device from malware

After you’ve successfully recovered from a mobile malware infection, make sure to update your device and security software to prevent another infection. Enabling Google Play Protect from within the app store also safeguards your device from rogue apps.

Ultimately, the best defense is to develop good security habits. Be cautious of everything you see online. Make sure to thoroughly vet apps before downloading them, and don’t click on links from unsolicited texts and emails. Also, avoid public Wi-Fi networks or, at the very least, use a virtual private network (VPN) to secure the connection.

Malware attacks can be devastating to your bottom line, but these tips should help mitigate the risks. If you want to learn more about how you can safeguard your Android devices, our experts are always willing to assist you. Contact us today.
