Threat Analysis: UK SMBs and Key Cyber Threats in July 2026
Hello, Mauven here. Today we’ve got a couple of cyber threats that UK SMBs need to watch like hawks. The focus is on ransomware campaigns that just don’t quit, and a critical vulnerability in Langflow.
First up, the home truth about ransomware: Over a third of victims end up being re-extorted after coughing up the first payment. This bit of cheery news comes courtesy of Proofpoint. Some victims also never see their files again, not really helping the stress levels, is it? If anyone in your circle is under the illusion that paying ransom will make cybercriminals go away, do enlighten them with these insights.
Next, the Cybersecurity and Infrastructure Security Agency (CISA) has ordered urgent action on a Langflow Remote Code Execution (RCE) flaw. This particular vulnerability (CVE-2025-3248) in the Langflow visual framework is actively exploited. AI infrastructure is at risk, which is something UK businesses dabbling in AI should take seriously. As usual, patch what’s known to be vulnerable.
This brings us to the latest concern, the new JADEPUFFER ransomware targeting AI models. They have built ransomware to destroy AI infrastructure, so if your business leans on machine learning or AI, it’s high time you look at those security patches.
Topping these off is the Adobe Chrome extension vulnerability. It could let attackers access your WhatsApp chats without a login. If you use WhatsApp Web for business communication, this is your cue to take corrective actions.
If you’re an SMB in the UK, consider these not just threats but calls for bolstering your defences. The risk extends beyond direct data loss to reputational harm and regulatory consequences. Keep your software up to date, back up your data, and ensure employees are trained against phishing.
Before the next story: if Threat Analysis is useful to you, follow the show wherever you listen, so tomorrow’s briefing lands automatically, and pass it to someone who needs the heads-up.
