Warning about malware

#200264

Postby tjh290633 » February 10th, 2019, 9:58 am

I just had need to go to the Weebly page and got a Google message about malware being detected there. I t suggests that care may be needed until Kiloran can look at it.

I went there too, probably at the same time and for the same reason (in response to a new post). I got no such warning.

Can you reproduce the warning? It would help Kiloran if you said which AV gave you that warning, and any other details like which browser and the steps you took that led to the warning.

For my part, I use W10's Defender with Smartscreen turned on. Browsers were Firefox and Edge.

This is the message that I got (using Chrome on Win10). It comes from Google rather than my own AV/Antimalware

The site ahead contains malware
Attackers currently on cdn2.editmysite.com might attempt to install dangerous programs on your computer that steal or delete your information (for example, photos, passwords, messages, and credit cards).

...

Google Safe Browsing recently detected malware on lemonfoolfinancialsoftware.weebly.com. Websites that are normally safe are sometimes infected with malware. The malicious content comes from cdn2.editmysite.com, a known malware distributor.

If you understand the risks to your security, you may visit this unsafe site before the dangerous programs have been removed.


As far as I am aware, this site is run by Kiloran rather than TLF. I have PM'd him to alert him to this.

Thanks for the warning.

It's certainly a concern, though I have no idea what is causing the report of malware. I've checked with two laptops on Windows 10 using Chrome, Firefox and Edge and don't get any warning messages. My laptops use Windows Defender and Comodo Firewall, and I regularly check both laptops with Malwarebytes. I can't remember the last time I got a virus or malware warning, it was certainly a very long time ago.

I just checked our Weebly site on https://transparencyreport.google.com/s ... ing/search and got no reports of any problems.

I've also changed the admin password for the site

Any experts got any other things I could check?

I just checked our Weebly site on https://sitecheck.sucuri.net/ and this does report a potential issue. I need to determine if https://sitecheck.sucuri.net/ is a reputable site, and if the report is correct or maybe a false positive.

Work continues....

The message which chas49 reproduced above is that which I got from Google on my Android mobile phone.

Interestingly that's the site you get to if you follow the links in the error message - and which also said there was a problem with "cdn2.editmysite (d0t) com" (link broken just to limit accidental clicks)

Visiting the site now shows no error!

I'm still investigating, but it appears that the cdn2.editmysite is third party software which is a fundamental part of Weebly, rather than anything I've inadvertently added. I'm trying to find out what the potential issue is. One analysis I have states
"​Third party content (such as images, JavaScript, or CSS) is loaded from external resources. Despite that for some web applications it can significantly improve loading time, it may also put website visitor's privacy at risk, as information about website visitors become accessible to these third-party content providers. ​Moreover, third-party content delivered via the HTTP channel and not HTTPS may expose your privacy."


The Weebly site is currently http and I do have the ability to change it to https which may improve security, but I'll tread carefully with this in case I irreversibly break something.

I doubt making the site https would help in this instance of upstream poisoning. Even if the entire chain were https, if the upstream site is compromised then any malware will propagate regardless.

Unfortunately, this type of hack is getting more and more prevalent, e.g. the BA website last year.

Just happened to notice this thread.

I'm didn't get a warning, but I use ad blockers so wonder if that is why. If cdn2.editmysite is third party software site, then I wouldn't see it and so wouldn't get the warning.
