The warning was issued by the Scottish Business Resilience Centre.
SBRC said a single supplier who was temporarily shut down as a result of a cyber attack could cause “major issues” for customers using its services as part of the supply chain.
The disruptions could include loss of vital customer details, it added.
A recent survey by PwC found a fall in the number of information security breaches affecting UK businesses over the last year.
However, it also suggested that the scale and cost of individual breaches had almost doubled.
The survey found 81% of large organisations suffered a security breach, which was 5% lower than a year earlier, while the number of small businesses reporting a breach also fell slightly.
But the average cost of an organisation’s worst breach rose for the third consecutive year.
SBRC cyber security consultant Oren Benshabat said: “Hackers who get into a company’s network could bring a business to its knees with just a few clicks of a mouse.
“When people think of the supply chain they often just think about manufacturers, wholesalers and retailers, but recently there is another side of the chain which has emerged.
“The cyber supply chain includes operations involving information and communication technologies, software distribution and operations within the cloud which is the backbone of today’s digital economy.
