Cybersecurity experts have encouraged people to do more to protect themselves from online crime, warning that 5G will only increase the potential devices that could be hacked
Raj Samani and Gary Davis, industry experts at cybersecurity firm McAfee, said that internet users were still making basic security errors such as using the same password in multiple places.
They said this continues to fuel crime online.
Mr Samani, chief scientist at the firm said: "You could stop the majority of cybercrime if people had strong passwords, they didn't have the same passwords on every account, they didn't click on every link".
"These simple things that we've been saying for 30 years. It is about getting that message across to people, showing them the vulnerabilities, the hacks that exist," he said.
"The objective isn't to scare people. The objective is to get people to understand that this is the reality of what's going on," he stated.
"We don't want you to be scared about using a mobile phone - you're going to use a mobile phone - but here's the threat. These are the detections, these are the banking attacks that are happening."
The pair were speaking during Mobile World Congress in Barcelona, a major technology trade show where the coming innovations in technology are showcased.
Among the most discussed themes of the convention has been 5G, the next generation of mobile communications technology which is due to start rolling out this year.
It is expected to be up to ten times faster than 4G, as well as be able to support more data and reduce any latency in processing it, enabling the wider rollout of technology such as autonomous cars.
Gary Davis, McAfee's chief consumer security evangelist, said while 5G would be a step forward for users, it also came with risks.
"What's going to happen is 5G is going to kick off like wildfire - everything's going to be connected up to 5G networks," he said.
"The bad guys are going to think 'what's the weakest point to get into the business or the home?', use that as a point of entry, sniff around and find what they want and the data is going to be out before you even know it because of the zero latency you have with 5G."
Mr Samani added that the work the cybersecurity industry does was crucial to combat this.
"If we don't have strong cybersecurity and strong privacy, you're not going to buy a self-driving car," he said.
"You're not going to have a fully automated power plant, none of it's going to exist without the foundation that this industry does.
"We need to have security and privacy integrated into every part of our life, it should be there throughout.
"There's no point saying it should've been there before, we need to start doing as much as we can today," he added.
At the trade show, McAfee announced its advanced threat research team had discovered two new vulnerabilities in common smart home devices - remote locking device BoxLock and Mr Coffee coffee machines.
Both issues have since been fixed, but McAfee warned in its announcement that "the possibility of your wi-fi-enabled toaster getting hacked and tweeting out your credit card number is, amazingly, no longer a joke."
