PIVX, Possibly Other PoS Chains Vulnerable to Bug, Attackers Profit

Private transactions cryptocurrency PIVX and over 200 other blockchains are vulnerable to attackers obtaining disproportionately high staking rewards.

A major staking vulnerability

Cryptocurrency consulting firm Lunar Digital Assets claimed in a post published on its website on Aug. 12 that a staking vulnerability is being used across PIVX and its forks. The weakness reportedly allows the attacker to obtain mathematically impossible staking rewards on vulnerable proof-of-stake (PoS) chains.

According to the post’s author, the PIVX development team claimed to have solved the issue in January. Nonetheless, a core developer of PoS altcoin BitGreen (BITG) noticed that the vulnerability in question is allegedly being exploited again. The consequences are explained in report in the following way:

“To put it bluntly, someone or some entity has figured out a way to game the PIVX PoS algorithm. This has crippled the rewards system of several chains, and BitGreen has notified of all exchanges that it is listed on to halt all deposits and withdrawals until further notice.”
