Over 40 Israeli importers and logistics firms were hacked after malicious actors compromised servers of Amital Data, a provider of software solutions for freight forwarders, shipping agents, airline cargo sales agents, and customs brokers, and stole the company’s list of customers, including their login information. This data was then used to hack into Amital Data client’s networks, Calcalist reports.

According to people familiar with the matter, at least 40 of Amital's customers were compromised at some level, however, the full list of hacked companies is still unknown, as well as who might have been behind the attack. Among the companies that use Amital are FedEx Trade Networks, Mentfield and Orian.

Furthermore, an investigation found that there may have been additional 15-20 companies, not Amital clients, that were also targeted in this cyber attack.

According to Yossi Rachman, Director of Security Research at Israeli cyber company Cybereason, the security breach appears to be a wide-scale intelligence operation, assuming it wasn’t random in nature.

In a statement Amital Data acknowledged that it had been hit with a cyber attack two weeks ago.

“Two weeks ago the company's defensive systems identified attempts to attack the company's computers, as well as those of some of its clients. The incident is part of a chain of events at a national level that are being investigated and monitored by the Israel National Cyber Directorate. As part of the company's protocol, the company's defense layers were strengthened and a dedicated operations room was set up in order to address any related issue. The company is using the assistance of experts in the cybersecurity sector in order to contain the incident. At this stage, there is isolated damage. We will regularly update on any development,” the company said.
