Privacy Startup Nym Hires Whistleblower Chelsea Manning to Audit Mixnet

Whistleblower and security engineer Chelsea Manning has joined privacy startup Nym as a security consultant, focusing on auditing their mixnet.

A mix network or “mixnet” (taking its name from the proxy servers it employs, called “mixes”) obscures the metadata left behind when data passes through a network, bringing a higher level of privacy to the table when it comes to network-level surveillance.

Manning’s audit will be completed before the Nym network launches on mainnet later in the year.

“As methods for network traffic analysis have dramatically improved in the last decade, I have frequently called for research (since 2016) into alternative methods to Tor that avoid exposing the data within the network to such analysis,” Manning said in a statement. “Nym is one such viable alternative worthy of research, and developmental implementation.”

Manning was imprisoned for leaking documentation regarding military operations in Iraq and Afghanistan, which included the U.S. targeting of civilians.

Nym’s ​initial testnet, launched in April 2020, was the victim of a Sybil attack. A Sybil attack is when a single actor tries to take over a network by spinning up multiple nodes that validate data and transactions on the network. If one actor has a disproportionate amount of control over the system, it compromises the system’s underlying integrity because the nodes under the attacker’s control could refuse to receive or transmit blocks on a blockchain.

“While trusting software with their money is one thing people are learning to do with Bitcoin and DeFi, brave whistleblowers and revolutionaries like Chelsea Manning have to trust software with their lives,” Nym CEO Harry Halpin said in a statement, adding:

“So rather than ‘YOLO’ and launch only to wreck their users, we’re working with the best people alive to keep our users safe and secure.”

Over the next month, Manning is tasked with discovering new privacy leaks and setting parameters for “cover traffic” on Nym’s mixnet.

Cover traffic is traffic that can help confuse an internet service provider or other centralized entity that can attempt network-level surveillance.

“We’d be happy to have her stay on after the audit in whatever form she wants, but right now we need everyone laser-focussed on securing our code,” said Halpin.
