The cybersecurity nonprofit Security Alliance (SEAL) warned that North Korean hackers are using fake Zoom meetings to carry out cryptocurrency scams, with attacks now occurring daily. Researcher Taylor Monahan said the method has caused losses of over $300 million, typically starting from compromised Telegram accounts and leading victims to download malware that steals passwords, private keys, and crypto assets. https://t.co/IA4qgghFZ9 ...

Bitcoin & Quantum Computing Risks - 大约三分之一的比特币供应量（约 670 万枚）存在于容易受到量子计算攻击的钱包中[2] - 其中 19% 位于旧钱包中，这些钱包默认使用密钥地址暴露公钥，量子计算可能通过公钥反向工程推导出私钥[2][3] - 另外 47% 百万枚比特币位于重复使用的地址中，虽然风险较低，但交易时公钥会被暴露，从而可能被反向工程推导出私钥[4] - 比特币社区需要转向量子抗性签名方案，但达成共识和迁移代币到量子安全地址可能需要 6 个月到 2 年的时间[7][8] - 量子计算公司预计在 2028 年至 2033 年间破解 ECC 椭圆曲线加密算法[12] - 比特币为量子霸权提供了一个巨大的漏洞赏金[12] Digital Asset Treasury (DAT) Companies & Market Dynamics - MicroStrategy 通过出售股票筹集了 144 亿美元的美元储备，用于支付优先股，这稀释了股东权益，此前该公司通常会将筹集的资金用于购买比特币[44] - MicroStrategy 等数字资产国库公司被迫去杠杆化可能标志着加密货币牛市的结束[45] - 市场担心数字资产国库公司发行的优先股的收益来源，因为比特币本身不产生收益，而这些优先股却支付 7% 到 1075% 的股息[49] - 市场普遍认为，数字资产国库公司是本轮周期中杠杆作用最明显的领域，可能面临风险[56] Zcash & Privacy - Zcash 因其屏蔽池（shielded pools）功能而受到关注，该功能可以隐藏所有权，且不暴露公钥，从而在技术上具有量子抗性[39][40] - 一些人猜测，比特币 OG 可能正在出售比特币，并通过 Zcash 转移资金以规避税收[40][41] - 普遍的隐私叙事也推动了对 Zcash 的关注[42]

Vulnerability Overview - OneKey reported a vulnerability affecting approximately 120 thousand Bitcoin private keys [1] - The vulnerability stems from Libbitcoin Explorer (bx) 3x, which uses system time and the Mersenne Twister-32 algorithm with a small 2^32-bit seed space, making keys predictable [1] Affected Products - Affected wallets include Trust Wallet Extension 00172–00183 and Trust Wallet Core ≤311 [1] - Other products using the same libraries are also affected [1]

Security Vulnerability - US law enforcement possesses private keys to 120 thousand bitcoins due to a randomness flaw [1] - The vulnerability affected over 220 thousand wallet addresses [1] - The private keys were generated by a flawed pseudo-random number generator (PRNG), making them more predictable [1] Law Enforcement Action - Law enforcement agencies obtained the private keys not through hacking, but by discovering a flaw in the key generation process [1]

Cryptocurrency Security - Industry emphasizes the importance of self-custody in cryptocurrency ownership: "not your keys not your crypto" [1] - The principle highlights the risk of losing access to crypto assets when relying on third-party custodians [1]

Security Practices - Avoid using Google Chrome extensions unless you understand their implications, and refrain from clicking links on devices used for cryptocurrency activities [1] - Do not save private keys online, including in pictures, screenshots, or notes [1] Risk Management - Secure cryptocurrency holdings exceeding $1,000 with a hardware wallet [1]
