Currency exchange specialist Travelex was warned about insecure virtual private networking (VPN) servers that it was running in September last year - but that warning appears to have been ignored.
The warning was issued by Chicago, Illinois-based security researcher Troy Mursch, tweeting under his @bad_packets account. He claims that he notified in the organisation about the vulnerable Pulse Secure VPN servers it was running on 13 September, but received no response from the company.
Travelex was one of a number of companies that Mursch informed, also informing the UK's National Cyber Security Centre at the same time. The NCSC sent out warning letters to affected organisations as a result of that warning.

But even now, according to UK-based security specialist Kevin Beaumont, a large number of organisations are still running iterations of Pulse Secure bearing a vulnerability identified 11 months ago.
And one-quarter of those vulnerable servers are located in the US, added Beaumont, at a time when Iran has threatened retaliation for the assassination of a senior general.
Today, the Travelex website and mobile app remain down with what the holding page describes as "planned maintenance". The website and associated currency exchange facilities were taken down on New Year's Eve following what the organisation had claimed was a virus outbreak.
Travelex's action has also affected currency exchange services from Barclays, HSBC, Sainsbury's Bank, First Direct and Virgin Money, which rely on Travelex. Users of the company's pre-paid foreign currency cards have also been affected, and left unable to top them up for more than a week.

The vacuum left behind by the lack of information about the nature of the attack has been filled with speculation, with anything from North Korean state actors to ransomware blamed for the extended downtime.

Security is always one of CIOs' top headaches, and the global pandemic hasn't improved matters. So what do organisations need to do in order to better protect themselves during the COVID-19 crisis?
