ChainCatcher news, according to Cointelegraph, AT&T will once again face allegations of failing to protect user information, as a previous favorable partial summary judgment has been overturned on appeal.The case began in 2020 when cryptocurrency investor Michael Terpin sued a recent high school graduate, accusing him of stealing $24 million worth of cryptocurrency from Terpin through SIM card swapping.
