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.Right now, with no special tools, someone could send an email that looks like it came from your company.The From line would show your domain, your logo could be pasted into the message, and it could ask one of your clients to pay an invoice or update banking details. This is called email spoofing, and it is one of the most

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. Microsoft reported a 146% rise in QR code phishing during the first quarter of 2026.QR codes are part of normal business now.You scan them to see a menu, pay for parking, connect to Wi-Fi, or open a shared document. Attackers know that, and they have started hiding malicious links inside QR codes to get past the security tools that would normally catch a bad link in an email.The technique has a name, quishing, and it works because a QR code is just an image.Your email filter reads text, so a link

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.What follows is a step-by-step walkthrough of how a small business gets attacked, written from the attacker’s side. The company in this account is composite, but the methods are accurate to current threat intelligence reporting. After the walkthrough, you’ll see five specific points where the attack would have been stopped by controls that come bundled with security tools most small businesses already pay for.Monday: how I picked youI work regular hours and run a small volume operation. My spreadsheet has about 40 prospects per month, and I prefer businesses between 10 and 50 staff. The reason for that

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. Not a zero-day exploit. Not a brute-force attack on a hardened system. Human behavior, in the course of an ordinary working day.For businesses running cloud-based workflows across multiple devices, the personal and professional overlap is now the rule. Understanding where that overlap creates risk is no longer optional. It is a core part of modern security strategy.The Risk Sitting Outside Your Security StackPersonal web habits are not reckless behavior. They are normal behavior.Checking a personal inbox on a work laptop. Logging into a social account during a break. Saving a work password in a browser already loaded with personal accounts. Uploading
