CASPER, Wyo. — Hilltop Bank has reopened select offices for limited transactions and launched dedicated phone lines, as officials continue working through a multi-day service outage caused by a cybersecurity breach.
That was the word from the bank in a Thursday morning social media post stating that limited transactions can now be processed at the main office, downtown office, MotorBank, Glenrock office and Cheyenne downtown office.
To field customer inquiries while main systems remain down, the bank opened a primary call center at 307-265-2740. Trust and Wealth Management clients are requested to direct their calls to 307-577-3305.
The branch reopenings follow full closures on Tuesday and Wednesday, triggered when staff first detected technical degradation across the IT infrastructure on Sept. 8. Shortly after midnight Wednesday, officials confirmed the disruption stemmed from a cybersecurity incident.
In response to the breach, administrators took all internal banking networks offline as a precautionary measure to isolate the environment and protect customer data. The shutdown temporarily disabled online banking, mobile banking and telephone customer service systems.
At time of publication, Oil City News has reached out to a Hilltop Bank representative seeking additional information and is awaiting responses. This story will be updated when more information is available.
Hilltop Bank and True Companies spokesperson Bill Salvin previously told Oil City News maintenance efforts are expected to extend over several days and possibly through the weekend, with no definitive timeline set for full reopening.
