Online banking security flaws may expose customers to fraud, claims consumer group | #emailsecurity | #phishing | #ransomware

Online banking customers are being left exposed to some worrying fraud risks, according to Which?

The consumer group is urging providers to “up their game” by using the latest protections for their websites and not allowing customers to set unsecure passwords.

It conducted an investigation with security experts 6point6, testing the online and mobile app security of 15 major current account providers on a range of criteria, including encryption and protection, login, and account management and navigation.

Six banks – HSBC, NatWest, Santander, Starling, the Co-operative Bank and Virgin Money – let people choose passwords that include their first name and/or surname, the research found.

Santander told Which? this was being phased out, while NatWest and Virgin Money said it might now increase password limitations.

TSB, Lloyds, Metro, Nationwide, Santander and the Co-operative Bank also used texts to verify people when logging in, leaving messages at risk of being hijacked by cybercriminals, Which? said.

Santander and the Co-operative Bank told Which? they were looking to move away from this.

Which? also claimed Nationwide, TSB and Virgin Money were not using software that ensured spoof messages sent by potential scammers were blocked or quarantined by an email provider. TSB told Which? it has since introduced this protection. Virgin Money said it was in the process of doing this. Nationwide said it had “a range of email security controls” to protect members.

HSBC came out most favourably for online banking security, scoring five stars for website encryption and account management. First Direct, a division of HSBC UK, was ranked top for mobile app security.

Which? tested the online and mobile app security of 15 major current account providers and found six that allowed clients to use passwords that included their first name or surname

Metro Bank was placed bottom for online security, while Monzo was ranked bottom by Which? for mobile app security.

Which? said Monzo did not ask people to log in every time, with the bank saying this was a “conscious design decision to strike a balance between risk and customer experience”.

A Monzo spokesman said: “We strongly disagree with this assessment. Given every sensitive action or payment requires a customer to provide extra authentication in the form of a Pin or biometrics, the risk associated with remaining logged into the Monzo app is extremely low.

“We take security incredibly seriously and focus on policies and practices that we consider to be safest for Monzo customers.”

Metro Bank said: “Like all financial institutions, we need to remain vigilant to protect our systems and security.

“In addition, we work with other banks collectively to help guard against fraud. We take our customers’ security extremely seriously and have a range of safeguards in place.”

Which? said the criteria it looked at included encryption and protection, login, account management, and navigation. It said every bank and building society had behind-the-scenes security processes and it was not possible for Which? to test these legally.

Jenny Ross, Which? Money editor, said: “Banks must lead the battle against fraud, yet our security tests have revealed worrying flaws when it comes to keeping people safe from the threat of having their account compromised.

“Our research reinforces the need for banks to up their game on tackling fraud by using the latest protections for their websites and not allowing customers to set insecure passwords. We also want banks to stop sending sensitive data to customers via SMS texts as this could leave the door open to fraudsters.”

TSB said it had several security features not captured in the results and highlighted its fraud refund guarantee. Virgin Money said: “We are continually monitoring, assessing and improving our security controls.” Co-operative Bank said it continually reviewed controls to maintain secure banking.

HSBC Group said: “We deploy advanced cybersecurity controls and identify and respond to threats in a timely manner.”

Lloyds Banking Group said: “We have robust, multi-layered security across online and mobile banking services to protect against cyber security threats. We employ world-class experts in the cyber-security field.”

Nationwide said: “We employ round-the-clock defences to monitor our systems and look out for suspicious activity.”

NatWest Group said: “We continue to invest in our digital security capabilities.” Santander said it continued to “invest a great deal in keeping our customers safe”.

Starling Bank said it had built security technology into its app and systems “to give customers an easy to use, secure, seamless experience”.
