The DreamHost breach exposed website login credentials, and anyone who used DreamHost’s web based File Manager since about August should change every FTP, SFTP and email password today. DreamHost says it found the intrusion on Friday, October 23, 2026, and that attackers reached FTP and SFTP usernames and passwords plus some webmail logins. If your website, your email or your developer’s access lives on a shared host, this story is a prompt to check your own setup this week.
We are FOG Digital Marketing in San Antonio, and we build and maintain websites for local businesses. A DreamHost breach is not only a DreamHost problem. The same weakness shows up when a host’s own tools are the way in, and the damage lands on the business owner’s website, inbox and customers. Below is what DreamHost said, who may be affected, and the exact checks to run.
Key Takeaways
- DreamHost discovered on October 23, 2026 that an unauthorized party had accessed the server running its web based File Manager at files.dreamhost.com.
- The attacker exploited a vulnerability in third party software and could read FTP/SFTP usernames and passwords of people who logged into File Manager from about August 2026 to October 23.
- Some webmail credentials were also obtained, and DreamHost believes a small number of mailboxes were viewed.
- DreamHost says well under about 10 percent of its email and FTP/SFTP accounts were affected, and it has found no evidence that control panel logins or billing details were accessed.
- Only the DreamHost account holder can set new mail and FTP/SFTP passwords, and any user who was signed out or whose old password stopped working was reset by DreamHost.
- Stolen hosting and email logins can lead to hacked website files, spam sent from your domain, and fake invoices that look real, so a quick check now is cheaper than a cleanup later.
What Did the DreamHost Breach Actually Expose?
According to DreamHost’s own October security incident notice, an unauthorized third party exploited a flaw in the third party software behind its browser based File Manager. That tool lets customers work on website files without a separate FTP program. The attacker could capture the FTP/SFTP usernames and passwords of users who logged into it before the activity was detected on October 23, and reach certain webmail systems to take the logins of a limited number of webmail users.
FTP and SFTP are the file transfer methods developers and site owners use to upload and edit the files that make up a website. A working FTP login is close to a master key for a standard website. Someone who has it can add a hidden file, change your contact form, or insert code that redirects visitors. DreamHost says it reset the affected passwords and ended active sessions the same day.
TechRadar’s report on the DreamHost breach adds the business risk: stolen mailbox access can fuel spam, phishing and business email compromise, a scam where a criminal writes to your customers from your real address. Not every detail is settled. DreamHost says its investigation is ongoing and it has not named who was behind it.
Was My Website or Email Affected?
You may be affected if you or an FTP/SFTP user on your account logged into File Manager between about August 2026 and October 23, 2026, or if an email user was signed out and the old password stopped working on or after October 23. DreamHost also says that if a previously working password still works and you never changed it, its investigation so far indicates that password was not exposed, though it still suggests changing it.
Do not rely on the absence of an email to decide you are safe. DreamHost admits fewer customers appear affected than first suspected, which also means the list changed while the investigation moved. If you cannot tell, DreamHost support can check your account. The practical answer for an owner is simple: assume the logins used in File Manager since August are compromised and rotate them.
How Does This Compare With Other Hosting Risks?
The table below shows what happened, what is still unknown, and what you should do about each part.
| What Happened | Details | When | Your Move |
|---|---|---|---|
| File Manager breach | An attacker exploited a flaw in the third party software behind files.dreamhost.com | Found October 23 | Treat any FTP/SFTP login used there as compromised |
| Exposed logins | FTP/SFTP usernames and passwords of people who logged in from about August to October 23 | Aug to Oct 23 | Change them and every place the password was reused |
| Webmail access | Credentials of a limited number of webmail users, some mailboxes viewed | Reset Oct 23 | Check forwarding rules and filters in every mailbox |
| Scale | Well under about 10 percent of email and FTP/SFTP accounts | Ongoing review | Do not assume you are safe because you got no email |
| Not affected so far | Control panel logins and billing details, per DreamHost | Investigation open | Still rotate passwords as a precaution |
The DreamHost breach follows the same pattern we saw in our post on the WordPress 7.1.3 security update. Your website is only as safe as the weakest login around it. Updates fix software, but shared passwords, old FTP users and forgotten mailboxes stay open until someone closes them.
What Is the Step by Step Plan to Secure My Site This Week?
Work through the steps below in order. A typical small business can finish them in about an hour, and they apply whether or not you use DreamHost.
5 Steps to Lock Down Your Website Hosting Today
Reset every FTP, SFTP and email password
Do it inside your hosting control panel, and use a different strong password for each user. Never reuse one across logins.
Delete saved passwords in your FTP and email apps
Old saved credentials cause lockouts and hide the fact that an old password was still in use.
Scan your website files for changes you did not make
Look at recently modified files, unknown admin users and odd PHP files in uploads folders. Compare against a clean backup.
Check mailbox forwarding rules and filters
Attackers hide inside quiet rules that copy your mail to another address. Remove any rule you did not create.
Turn on two step login everywhere you can
Use it on your hosting account, WordPress admin and email. Then ask your host which login types support it.
If you do not know who your FTP users are, that is your first finding. Many websites carry old logins for a former developer, a past agency or a plugin that needed a connection years ago. Each one is a door. Our website maintenance plans include login audits, backups, updates and malware checks so those doors do not pile up.
What Should I Check on My Website Right Now?
Start with change history. In your hosting panel, sort files by last modified date and look for anything changed since August that you or your developer did not touch. Pay special attention to the wp-content/uploads folder, any file with a random looking name, and the index and configuration files in your site root. If you run WordPress, open Users and confirm every administrator is someone you recognize.
Next, test the front of the site the way a customer would. Submit your contact form and confirm the message reaches the right inbox. Load the site on your phone from a mobile data connection and watch for redirects or pop ups. A hacked site often looks normal to the owner and wrong only to visitors from search or ads. A technical SEO review also catches hidden spam pages and injected links that hurt your rankings before you ever see them.
Finally, confirm you have a clean backup stored somewhere other than the same hosting account. If your site is ever compromised, a backup from before August lets you restore fast instead of rebuilding from scratch. Our San Antonio web design team builds every site with off server backups and a short list of named logins for exactly this reason.
What Should I Do About My Business Email?
Treat email as part of the DreamHost breach cleanup. Change the password on every mailbox DreamHost reset, and open each one in webmail. Check Settings for forwarding addresses, auto replies and filters that move mail to a hidden folder, because attackers use quiet rules to watch invoices and password resets. DreamHost lists forwarding rules and filters among the things to check.
Then warn your team and your best customers. If a criminal can read your mailbox, they can copy a real invoice and change the bank details. Tell your staff that payment instructions arrive by phone call confirmation only. DreamHost notes that attackers often follow breaches with scam emails that imitate the company involved, and that it will never email you asking for your password. Treat any message asking you to sign in through a link as suspect, and type the control panel address yourself.
Your landing pages and forms matter too. If your forms send leads to a hosted mailbox, a compromised mailbox means a competitor or scammer could see every new inquiry. Moving lead notifications into a CRM or a form service with its own login gives you a second copy and a record. Our landing page design work builds that safety net into every form. Our recent post on Google’s URL rules is another example of a technical detail that quietly affects a website without the owner ever noticing.
Common Mistakes We See After a Hosting Breach
- Changing only the control panel password. The exposed logins were FTP, SFTP and webmail users, which are separate from the main account login.
- Reusing the old password with one digit changed. DreamHost advises unique passwords for every user, and attackers test small variations first.
- Waiting for an email before acting. The affected group changed as DreamHost reviewed its logs, so a missing notice is not a safety guarantee.
- Forgetting saved passwords in apps. Phones and desktop email programs keep trying old logins and can lock you out or mask a problem.
- Skipping mailbox rules. A forwarding rule keeps working after the password changes unless you delete it.
- Leaving former developers on the account. Every unused FTP user is another login that can be stolen.
Frequently Asked Questions
Was my DreamHost website hacked in the breach?
Not necessarily. In the DreamHost breach, the attacker took logins and may have viewed some mailbox contents, but DreamHost has found no evidence of access to control panel logins or billing details, so your site files are at risk only if an exposed FTP/SFTP login was used against them.Which DreamHost passwords should I change?
Change every FTP, SFTP and email user password on your account, starting with any user who logged into File Manager since about August 2026. Only the account holder can set the new passwords from inside the DreamHost control panel, and a change can take up to 15 minutes to apply.How do I know if hackers changed my website?
Check your files for recent modifications you did not make, look for unknown administrator users, and compare the site against a clean backup. A San Antonio SEO company can also check Google Search Console for sudden spam pages or security warnings.Should I move to a different web host after a breach?
Not automatically. The DreamHost breach is a reason to review how the host responded and how your own accounts are set up, and DreamHost says it took File Manager offline, patched the flaw and rebuilt it with extra monitoring, so weigh that against your own risk tolerance.Does this affect customers of other hosting companies?
The DreamHost breach involves one provider only, but the lesson applies everywhere. Unique passwords, two step login, a short list of named users and off server backups protect a website no matter which host you use.
A DreamHost breach is a reminder that a website is a set of logins as much as a set of pages. Spend an hour this week on the five steps above, and write down who has access to what. FOG Digital Marketing helps San Antonio businesses audit hosting, email and website access so a headline about someone else’s hosting provider stays someone else’s problem.
