Shipping technology giant Pitney Bowes has confirmed a cyber attack on its systems.
The company said in a statement that the systems were hit by a "malware attack that encrypted information" on the systems, more commonly known as ransomware.  "At this time, the company has not seen any evidence that customer or employee data has been misused," the statement states, but many of its internal systems are disconnected, causing disruption to client services and other business processes .
The company said it is working with a third-party consultant to solve the problem. But it is not immediately known what kind of ransomware encrypted systems.
A spokesman, when reached, did not comment beyond the published statement.
Pitney Bowes is a widely used shipping company providing postal services to merchants, with more than 1.5 million customers worldwide, including the Fortune 500. The company allows merchants to make mail shipments and goods easier and more efficient, and is a great deal used by sellers in marketplaces such as Etsy and Shopify.
Several Twitter customers complained that they were unable to perform basic tasks on their account. It is known that some account and product support sites and downloads are not available.
It is the latest in a series of attacks on high-profile businesses. In recent months, the beverage giant Arizona Be drinks, aluminum producer Norsk Hydro and the scientific services company Eurofins have all been hit by ransomware.
Last week, the FBI warned about high-impact ransomware attacks on larger businesses.
