Summary: Changing the password blocks someone from signing in with the old password. However, they may still have an active session, a forwarding rule, access through a connected app, mailbox permissions, or a recovery method they added.
Article Summary: A passkey lets you sign in to an app or website using the same fingerprint, face, or PIN you use to unlock your phone or laptop, with no password to type. It's built on a security standard called FIDO that can't be phished, because the passkey only works on the real site and there's no password to steal or reuse.
Article Summary: Email spoofing is when a scammer sends a message that appears to come from your domain, often to trick your clients or staff into paying a fake invoice or changing banking details. Three DNS records (SPF, DKIM, and DMARC) prove that a message really came from you and tell receiving mail servers to reject the ones that didn't. The catch is that DMARC only protects you once it's set to "quarantine" or "reject," and a lot of businesses leave it on "none," which monitors but does not block.
Article Summary: A QR code scam, sometimes called quishing, hides a malicious web link inside a QR code. Because the link is buried in an image instead of written as text, it slips past the email filters that normally catch bad links, and scanning the code usually moves the victim onto a personal phone that sits outside the company's security.
Small businesses are the most common ransomware target by volume of incidents, even though many small business owners assume hackers focus on larger organizations. A 22-person company has enough revenue to be worth attacking, no dedicated security team to defend it, and a publicly traceable footprint that takes about an hour to research.
Most cyberattacks do not start with a sophisticated intrusion. They start with a click on a personal email, a reused password, or a file uploaded to a familiar cloud service because the approved option felt slower.
The Verizon Data Breach Investigations Report found that 68% of breaches involve the human element.
