Schneier - On the Security of Password Managers

Good article on password managers that secretly have a backdoor.

New research shows that these claims aren’t true in all cases, particularly when account recovery is in place or password managers are set to share vaults or organize users into groups. The researchers reverse-engineered or closely analyzed Bitwarden, Dashlane, and LastPass and identified ways that someone with control over the server­—either administrative or the result of a compromise­—can, in fact, steal data and, in some cases, entire vaults. The researchers also devised other attacks that can weaken the encryption to the point that ciphertext can be converted to plaintext.

This is where I plug my own Password Safe. It isn’t as full-featured as the others and it doesn’t use the cloud at all, but it’s actual encryption with no recovery features.

KnowBe4 - Uncovering the Sophisticated Phishing Campaign Bypassing M365 MFA

Image
Lead Analysts: Jeewan Singh Jalal, Prabhakaran Ravichandhiran and Anand Bodke KnowBe4 Threat Labs has detected a sophisticated phishing campaign targeting North American businesses and professionals. This attack compromises Microsoft 365 accounts (Outlook, Teams, OneDrive) by abusing the OAuth 2.0 Device Authorization Grant flow, bypassing strong passwords and Multi-Factor Authentication (MFA). The victim is directed to the legitimate Microsoft domain ( microsoft.com/devicelogin ) portal to enter an attack-supplied device code. This action authenticates the victim and issues a valid OAuth access token to the attacker’s application. The real-time theft of these tokens grants the attacker persistent access to the victim’s Microsoft 365 accounts and corporate data. from Human Risk Management Blog https://blog.knowbe4.com/uncovering-the-sophisticated-phishing-campaign-bypassing-m365-mfa
