The unauthorized coins were indistinguishable from legitimate ZANO, leaving the team unable to remove them without rolling back the blockchain. Zano revealed that the attacker who exploited its Gateway Address vulnerability over the last month used it to create 36.9 million Zano (ZANO), along with Freedom Dollar (fUSD) tokens, before the decision was made to roll the blockchain back by a month.  In a post-mortem published Thursday, Zano said the attacker first exploited the vulnerability on Aug. 29, creating approximately 18.4 million ZANO in a single transaction. The attacker repeated the exploit on Sept. 25, minting another 18.4 million ZANO, before using the same method to create fUSD. The team said a portion entered the Zano ecosystem.  “These coins functioned as authentic ZANO and could be spent normally,” the team wrote in its post-mortem. Cointelegraph reached out to Zano for comment. Read more

Team members’ personal funds and committed contributors are also in the plan, while claims rules and payment amounts remain undisclosed. The post Zano rolls back a month of transactions as team plans to use personal funds for recovery appeared first on CryptoSlate.

The Zano blockchain has been restarted at the block height that came immediately before Hard Fork 6, which introduced Gateway Addresses. Zano has rolled back approximately a month of blockchain history after a vulnerability involving Gateway Addresses allowed unauthorized ZANO and Freedom Dollar to enter circulation, according to its core team.  The Zano blockchain has been restarted at block 3,833,000, immediately before Hard Fork 6, which introduced the affected feature. The recovery requires participating nodes, miners, stakers, exchanges and other services to adopt the update, the team said Sunday.  The rollback invalidates a month of legitimate transactions along with the unauthorized tokens, meaning transactions made during that period will no longer appear on the recovered chain. It also cannot reverse payments already settled on other blockchains. The team said it is working to account for any losses and will publish a reimbursement and claims process.  Read more
