The IRS is looking for help to break into cryptocurrency hardware wallets, according to a document posted on the agency website in March of this year.

Many cryptocurrency investors store their cryptographic keys, which confer ownership of their funds, with the exchange they use to transact or on a personal device. Some folks, however, want a little more security and use hardware wallets—small physical drives which store a user's keys securely, unconnected to the internet. The law enforcement arm of the tax agency, IRS Criminal Investigation, and more specifically its Digital Forensic Unit, is now asking contractors to come up with solutions to hack into cryptowallets that could be of interest in investigations, the document states.
