ChainCatcher 消息，据 CoinDesk 报道，美国国税局（IRS）发布警告称，一场针对美国加密货币持有者的高级邮件钓鱼活动正在扩散，攻击者通过伪造官方税务信件，诱导用户扫描恶意二维码，以窃取加密钱包凭证和私钥。
据悉，攻击者冒充 IRS 发送纸质信件，利用“税务合规”“账户验证”等名义制造紧迫感，并在信件中附带二维码。一旦用户扫描，可能被引导至仿冒网站，进而泄露钱包登录信息、助记词或私钥，导致数字资产被盗。
IRS 提醒纳税人，官方机构不会通过非官方渠道要求用户提供加密钱包私钥、助记词或进行类似“钱包验证”操作。加密货币持有者应警惕任何要求扫描二维码、连接钱包或提交敏感信息的可疑邮件和信件。
随着加密资产持有者规模扩大，针对数字钱包的社会工程攻击持续增加，监管机构和安全机构正加强对相关诈骗活动的防范提醒。
