Cyber Crime Message – Mobile Device Security

cybercrime

A 2023 survey found that there are 700,000 more mobile phone subscriptions in Ireland than there are people. Mobile phones have replaced laptops as the primary device we use to connect online - 95% of people have a mobile phone, while almost 90% of people access the internet every day using their phones to connect to the internet, social media and email. At the same time, over 55% of children aged 9-11 own a smartphone which connects them to social media and the internet, often without restriction or supervision.  A survey by Webwise found that 65% of parents are unaware of their child’s online activity. We forget that mobile phones are a storage device, a processing computer, a photo gallery, a navigation aid, a mobile bank and a communication hub all combined. Most people use mobile phones for more reasons than any other device they have access to.

 

Because the phone is in our pocket we believe it is secure and safe. But that’s not always the case.They are nearly always on and connected to a network and the Internet. Insecure Wi-Fi doesn’t necessarily encrypt the personal data we send and doesn’t always require a password or other form of credential to be entered. At the same time, our phones are designed to connect to other devices through Wi-Fi or Bluetooth. This allows files and data to be shared between devices and transfer files very easily.

 

It has been recognised that our phones carry valuable data and are being targeted by organised criminal groups (O.C.G) - resulting in the data being stolen. Mobile phishing emails have increased by 85%, while many O.C.G’s are creating fake apps that are designed to capture your interest and then your personal information. We make that easier if we don’t update our mobiles with official software patches, anti-virus protections or just lock it down by turning off connection apps such as Bluetooth unless you actually need to use them. Around 60% of people update protections on their mobiles regularly, with many workers expecting their IT section organise the updates for them.

 

Most mobile phone suppliers provide annual system upgrades and regular updates to software to include patches and fixes for bugs which improve performance and security. Users are asked to permit the upgrade which can be rejected or delayed because it can change features on the phone, but that increases the risk of infection with malware or a cyber-attack. We should always check for updates ourselves.

 

Basic Rule of Mobile Phone Usage

cybercrime2

  • Treat your phone as a computer
  • Update your phone’s software and virus protections regularly
  • Only install known and trusted apps
  • Avoid using unsecure free Wi-Fi to connect your phone to the internet or a work network
  • Use a separate password or biometric logon such as a fingerprint to lock your phone
  • Turn on encryption on your Android phone. You can find out how by searching on Google (With Android its Settings & Security) iPhones have encryption by default when protected with a password or other lock.
