Nefilim ransomware gang leaks Toll documents on dark web Featured

The attackers behind an ongoing ransomware attack on Australian logistics and transport provider Toll Holdings have released some documents which they claim to have exfiltrated from the company when they staged the attack.

The ransomware in question is named Nefilim and it attacks Windows systems.

News of the attack, the second this year, was announced by Toll on 5 May, with the company saying at the time that it had shut down some of its systems as a precaution.

The documents released on Wednesday on the dark web include statements about company financials in plain text and a zipped file. This indicates that the ransom demand by the group has not been met by Toll. The attackers claim to have more than 200GB of company data.

Contacted for comment, a Toll spokesperson directed iTWire to this statement: "Following our announcement last week that a ransomware attacker had stolen data contained on at least one Toll corporate server, our ongoing investigation has established that the attacker has now published to the dark web some of the information that was stolen from that server.

"As a result, we are now focused on assessing and verifying the specific nature of the stolen data that has been published. As this assessment progresses, we will notify any impacted parties as a matter of priority and offer appropriate support."

Toll, which has been in operation for more than 125 years, is part of Japan Post. It has operations in 1200 regions across the globe in 50 countries.

The firm has about 40,000 employees. For the full-year 2019, the Toll Group had revenue of US$8.7 billion.

Asked for comment, ransomware researcher Brett Callow, who works for the New Zealand-headquartered security outfit Emsisoft, said: "For a major company to be hit by two different ransomware groups within a relatively short space of time is highly unusual but not without precedent.

"It’s not at all unusual for groups to leave behind backdoors. The backdoors are typically 'owned' by affiliates who may change allegiance or sell or trade them with other groups."

The first attack on Toll earlier this year was said to have involved ransomware known as Mailto.

"Consequently, a successful attack by one group could potentially result in a successful attack by another," said Callow. "This is one of the reasons that we strongly recommend that companies completely rebuild their networks post incident."

Active Vs. Passive DWDM Solutions

An active approach to your growing optical transport network & connectivity needs.

Building dark fibre network infrastructure using WDM technology used to be considered a complex challenge that only carriers have the means to implement.

This has led many enterprises to build passive networks, which are inferior in quality and ultimately limit their future growth.

Why are passive solutions considered inferior? And what makes active solutions great?

Read more about these two solutions, and how PacketLight fits into all this.
