Malicious attackers who used the Windows REvil ransomware to attack Nexia Australia and New Zealand, a network of solutions-focused accountancy and consultancy firms, have re-listed the company on their dark web site, along with screenshots of data that has been allegedly filched during the attack.

As iTWire reported on Thursday, the listing had been removed, something that normally happens when a victim pays whatever ransom has been demanded or else is negotiating with the attackers.

But a security source said it now looked like the first listing had been done to push the company into paying up.

Now after waiting a while and realising that this was not going to happen, the attackers had again listed Nexia, the source added. The attackers have said on the site that they would soon release the data that was stolen.

Nexia has denied that any data was stolen, based on reports from external IT consultant, Systima, a managed services provider, which was called in to deal with the incident, and the ISP Vocus.

In a statement provided last week, a Nexia spokesperson said: "The matter was swiftly dealt with by our external providers and co-ordinated by our in-house ICT manager and we are advised that there is no evidence of any movement of data/files," the spokesperson said.

"As part of the process passwords were changed, servers were patched and firewalls were geo-locked. Our systems continue to be monitored as per our standing arrangements."

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
