How ransomware gets in: the common paths that still work.
Most ransomware incidents do not begin with a movie-style hack. They begin with normal access used in the wrong way.
The opening is usually ordinary access used in the wrong way.
Attackers look for the easiest path into the business. Sometimes that is a phishing email. Sometimes it is a reused password, an exposed remote desktop login, or a vendor account that nobody reviewed in years.
Buying lens: the best tool is not the one with the longest feature list. It is the one that reduces the easiest paths into your environment and limits what a single account can reach.
Email and attachments
Phishing still works because it looks like work. A fake invoice, delivery notice, resume, bank message, or document share can pressure an employee into opening a file or approving a login. The first click may not install ransomware immediately. It may install a loader, steal a password, or give the attacker a foothold.
Remote access and stolen credentials
Remote Desktop, VPN portals, admin tools, and cloud accounts are valuable because they already have permission to enter the environment. If an attacker gets a valid password, the activity can look legitimate at first. MFA helps a lot, but only when it is enforced consistently and users know not to approve unexpected prompts.
Unpatched software and exposed services
Some attacks skip the inbox and exploit known weaknesses in servers, appliances, or remote access software. This is why patching matters. A vulnerability that looks like a technical housekeeping item can become the front door for an attacker once public exploit code appears.
USB devices and local access
USB risk is easy to underestimate. A malicious or unknown device can introduce scripts, tools, or files that bypass normal download controls. In smaller offices, shared machines and front-desk computers are common places where this risk shows up.
Vendor and shared-account risk
Many businesses depend on outside IT providers, accounting systems, file sharing tools, and line-of-business software. Those relationships create useful access, but they also create risk. If a vendor account has broad permissions, one compromised login can reach more than expected.
What to do before buying another tool
Start by mapping access. Which users have admin rights? Which remote access tools are open? Which machines can reach shared folders? Which accounts can disable security tools or delete backups?
Then add controls that reduce blast radius. Require MFA, patch exposed systems, remove unnecessary admin rights, limit shared-drive access, review vendor accounts, and monitor endpoint behavior. AI Wall fits into that last category by watching Windows endpoints for risky behavior and giving teams evidence when something needs attention.
Want help seeing where ransomware could reach your business?
AI Wall can be piloted on a small set of Windows machines so your team can evaluate endpoint visibility, USB risk controls, and ransomware-like behavior alerts before expanding deployment.
