Dealing with cybersquatting, typosquatting and phishing

It won’t be a secret to say that phishing remains one of the most effective attack vectors.

For example, your colleague receives by email a malicious web link that looks like a link to your corporate portal and opens it. If your Vulnerability and Patch Management programs are not good enough (see “WannaCry about Vulnerability Management“) and the software on his desktop has some critical and exploitable vulnerabilities in web browser, PDF reader, Microsoft Office, etc., you will probably get compromised host in your network.

This is also a pain for your customers. If someone will be sending messages on behalf of your organization, this can easily lead to fraud and costs in public image. And it will be even harder to detect. You will know about it only if they tell you. And if the attack was not massive, the probability of this is not very high.

High-Tech Bridge Trademark Abuse Radar summary

What can we do about this?

  • We should definitely raise the awareness among co-workers and clients. They should know that such attacks may occur and carefully check the domain before any click. Especially if the letter seems suspicious.
  • On the other hand, we can also act proactively. Find which domains are similar enough to company brand and can be potentially used for phishing or other types of fraud. Then work with owners or registrars of such domains directly.

However, tracking down potentially malicious domains is not an easy task. Where should we take the lists of  all registered domains? What does “similar enough” really mean? Fortunately, there are services that greatly facilitate this task.

And today I would like to write you about a new free service by High-Tech Bridge – Trademark Abuse Radar. BTW, I already wrote earlier about their cool free service and API for SSL/TLS server testing, you can also check this out 😉

Everything is simple. Just enter the domain name you are interested in and in a few minutes you will receive a full report. No authorization for analysis is required, because the report is built on external and open data.

I chose the Citibank (citibank.com) as one of the most famous banking brand in the world. Let’s see what Trademark Abuse Radar will find.

Use multiple vulnerability scanners in the name of good

About a month ago I wrote a post “When a free scanning service detects vulnerabilities better”. This post was about OpenSSL CVE-2016-2107 vulnerability. A free High-Tech Bridge scanning service was detecting this vulnerability, but commercial Tenable Nessus/SecurityCenter not.

We communicated with a Tenable customer support and it brought some results. Now you can find a new plugin #91572 “OpenSSL AES-NI Padding Oracle MitM Information Disclosure” in Nessus plugin search (by CVE id CVE-2016-2107).

New CVE-2016-2107 Nessus plugin

I have tested a vulnerable server with High-Tech Bridge service:

HTBridge detects vulnerability

Then scanned it with Nessus. Note, that you can select only one plugin “General -> 91572” in your Nessus scan policy to speed up the scanning. This plugin does not have any dependencies.

Nessus detects vulnerability

As you can see, now the Nessus detects this vulnerability correctly.

The screenshot shows that it took more than a month, but after all this detection plugin was realized. And I hope my support tickets also played some role.

Nessus plugin

Therefore, I recommend, if it is possible, to validate your vulnerability scan results with additional scanners/services and REPORT your vendor the differences. It will help to achieve a better security level for your infrastructure and will make the your vendor’s products better.

When a free scanning service detects vulnerabilities better

We all want to have a reliable and efficient Vulnerability Scanner. This scanner should be able to find any vulnerabilities immediately, as soon as the information about them is published. And, to be honest, no one wants to research how the scanner do it. Really. It’s not our job. We purchased the product, we trust the vendor and if this product does not work as we would like, it is a vendor’s problem. Is that right?

Not really. If we do not properly recognize the condition of our infrastructure and do not properly assess the risks, because of this vendor’s faults, this would be our problem. It’s relatively easily to find out that some detected vulnerabilities from scanning report are false positives, what if scanner didn’t find an existing vulnerability? How would you even know this happened?

That’s why we still have to understand how the scanners work, to watch the watcher.

A recent example. CVE-2016-2107: OpenSSL AES CBC cipher information disclosure.

upd. For this vulnerability Tenable released addition detection plugin: “Use multiple vulnerability scanners in the name of good”.

HT Bridge detects CVE-2016-2107 vulnerability, Nessus not

This vulnerability may be detected by free vulnerability scanning services and practically could not detected by Nessus via unauthenticated scanning. You can see on the screenshots how we have scanned the same host with Nessus and free service by High-Tech Bridge. And Nessus did not detect CVE-2016-2107.

High-Tech Bridge service and API for SSL/TLS server testing

Another great free SSL security testing service — High-Tech Bridge SSL Server Test (and Free API). I have already reviewed something quite familiar – Qualys SSL Labs client. So naturally there will be an element of comparison.

High-Tech Bridge SSL/TLS test request

Why have I tried something else after Qualys SSL Labs? The thing is Qualys doesn’t support IP addresses as a target. Maybe they don’t want it to be used for assessing full IP-ranges. I don’t know. But the fact is “IP addresses are not allowed”.
