Controversies

Symantec

In response to Symantec's comment over the effectiveness of free Antivirus software, on September 18, 2010, the CEO of Comodo Group challenged Symantec to see which products can defend the consumer better against malware. GCN'S John Breeden understood Comodo's stance on free Antivirus software and challenging Symantec: "This is actually a pretty smart move based on previous reviews of AV performance we've done in the GCN Lab. Our most recent AV review this year showed no functional difference between free and paid programs in terms of stopping viruses, and it's been that way for many years. In fact you have to go all the way back to 2006 to find an AV roundup where viruses were missed by some companies."

Symantec responded saying that if Comodo is interested they should have their product included in tests by independent reviewers.

Comodo volunteered to a Symantec vs. Comodo independent review. Though this showdown did not take place, Comodo has since been included in multiple independent reviews with AV-Test, PC World, Best Antivirus Reviews, AV-Comparatives, and PC Mag.

Certificate hacking

On March 23, 2011, Comodo posted a report that 8 days earlier, on 15 March 2011, a user account with an affiliate registration authority had been compromised and was used to create a new user account that issued nine certificate signing requests. Nine certificates for seven domains were issued. The attack was traced to IP address 212.95.136.18, which originates in Tehran, Iran. Though the firm initially reported that the breach was the result of a "state-driven attack", it subsequently stated that the origin of the attack may be the "result of an attacker attempting to lay a false trail.".

The attack was immediately thwarted, with Comodo revoking all of the bogus certificates. Comodo also stated that it was actively looking into ways to improve the security of its affiliates.

In an update on March 31, 2011, Comodo stated that it detected and thwarted an intrusion into a reseller user account on March 26, 2011. The new controls implemented by Comodo following the incident on March 15, 2011, removed any risk of the fraudulent issue of certificates. Comodo believed the attack was from the same perpetrator as the incident on March 15, 2011.

In regards to this second incident, Comodo stated, "Our CA infrastructure was not compromised. Our keys in our HSMs were not compromised. No certificates have been fraudulently issued. The attempt to fraudulently access the certificate ordering platform to issue a certificate failed."

On March 26, 2011, a person under the username "ComodoHacker" made several posts to Pastebin.com claiming to be an Iranian responsible for the attacks.

Such issues have been widely reported, and have led to criticism of how certificates are issued and revoked. As of 2016, all of the certificates remain revoked. Microsoft issued a security advisory and update to address the issue at the time of the event.

Such attacks are not unique to Comodo - the specifics will vary from CA to CA, RA to RA, but there are so many of these entities, all of them trusted by default, that further holes are deemed to be inevitable.

Association with PrivDog

In February 2015, Comodo was associated with a man-in-the-middle enabling tool known as PrivDog, which claims to protect users against malicious advertising.

PrivDog issued a statement on February 23, 2015, saying, "A minor intermittent defect has been detected in a third party library used by the PrivDog standalone application which potentially affects a very small number of users. This potential issue is only present in PrivDog versions, 3.0.96.0 and 3.0.97.0. The potential issue is not present in the PrivDog plug-in that is distributed with Comodo Browsers, and Comodo has not distributed this version to its users. there are potentially a maximum of 6,294 users in the USA and 57,568 users globally that this could potentially impact. The third party library used by PrivDog is not the same third party library used by Superfish....The potential issue has already been corrected. There will be an update tomorrow which will automatically update all 57,568 users of these specific PrivDog versions."

Certificates issued to known malware

In 2009 Microsoft MVP Michael Burgess accused Comodo of issuing digital certificates to known malware.

Comodo responded when notified and revoked the issued certificates that contained the rogue malware.

Chromodo browser, ACL, no ASLR, VNC weak authentication

In January 2016, Tavis Ormandy reported that Comodo's Chromodo browser exhibited a number of vulnerabilities, including disabling of the same-origin policy.

The vulnerability wasn't in the browser itself, which was based on the open-source code behind Google's Chrome browser. Rather, the issue was with an add-on. As soon as Comodo became aware of the issue in early February 2016, the company released a statement and a fix: "As an industry, software in general is always being updated, patched, fixed, addressed, improved - it goes hand in hand with any development cycle...What is critical in software development is how companies address an issue if a certain vulnerability is found - ensuring it never puts the customer at risk." Those using Chromodo immediately received an update. The Chromodo browser was subsequently discontinued by Comodo.

Ormandy noted that Comodo received a "Excellence in Information Security Testing" award from Verizon despite the vulnerability in its browser, despite having its VNC delivered with a default of weak authentication, despite not enabling address space layout randomization (ASLR), and despite using access control lists (ACLs) throughout its product. Ormandy has the opinion that Verizon's certification methodology is at fault here.

Let's Encrypt trademark registration application

In October 2015, Comodo applied for "Let's Encrypt", "Comodo Let's Encrypt", and "Let's Encrypt with Comodo" trademarks. These trademark applications were filed almost a year after the Internet Security Research Group, parent organization of Let's Encrypt, started using the name Let's Encrypt publicly in November 2014, and despite the fact Comodo's "intent to use" trademark filings acknowledge that it has never used "Let's Encrypt" as a brand.

On June 24, 2016, Comodo publicly posted in its forum that it had filed for "express abandonment" of their trademark applications.

Comodo's Chief Technical Officer Robin Alden said, "Comodo has filed for express abandonment of the trademark applications at this time instead of waiting and allowing them to lapse. Following collaboration between Let's Encrypt and Comodo, the trademark issue is now resolved and behind us, and we'd like to thank the Let's Encrypt team for helping to bring it to a resolution."

Dangling markup injection vulnerability

On July 25, 2016, Matthew Bryant showed that Comodo's website is vulnerable to dangling markup injection attacks and can send emails to system administrators from Comodo's servers to approve a wildcard certificate issue request which can be used to issue arbitrary wildcard certificates via Comodo's 30-Day PositiveSSL product.

Bryant reached out in June 2016, and on July 25, 2016, Comodo's Chief Technical Officer Robin Alden confirmed a fix was put in place, within the responsible disclosure date per industry standards.
