Heroku: Starting December 2021, #SMS will no longer be available as an MFA verification method.

The #security risks associated with use of SMS:

> If not (and the user happens to protect her or his VoIP account with a password), the user might now be protecting sensitive personal information with two passwords—that's two of one factor type (two of ‘something you know’) rather than actual two factor authentication (‘something you know’ and ‘something you have’).

> Following on our approach to limit scalability and remote attacks, security researchers have demonstrated the increasing success (read: lower cost in time and effort and higher success rates) of redirecting or intercepting SMS messages en masse.

在黑客利用 Coinbase 基于短信的双因素认证系统的漏洞入侵账户后,超过6000名 Coinbase 用户的账户资金被盗。

该交易所在提交给美国各州检察长办公室的数据泄露通知书中说,入侵发生在今年早些时候,即3月至5月之间。

Coinbase 说:“第三方利用了 Coinbase 短信账户恢复流程中的一个缺陷,以接收短信双因素认证令牌,并获得对您的账户的访问”。

Coinbase说,只有在知道受害者的用户名和密码的情况下,这些攻击才能利用这个漏洞。

“虽然我们无法最终确定这些第三方是如何获得这些信息的,但这种类型的活动通常涉及网络钓鱼攻击或其他社交工程技术,以欺骗受害者在不知情的情况下将登录凭证透露给不良行为者”。

根据 CoinMarketCap 的数据,Coinbase 是当今世界上第二大加密货币交易所,仅次于 Binance。

#npm’s culture presents a major problem for global software #security. It’s grossly irresponsible to let dependency trees grow to thousands of dependencies, from vendors you may have never heard of and likely have not critically evaluated, to solve trivial tasks which could have been done from scratch in mere seconds, or, if properly considered, might not even be needed in the first place.
