Is your hosted email domain ready for Google’s & Yahoo’s DMARC requirements?

DMARCStarting in February of 2024, Google, Yahoo, and others, will begin requiring that DMARC, SPF, and DKIM, be properly set up on your domain name, if you will be sending email, from your email domain, to them. DMARC, SPF, and DKIM, help authenticate email senders by verifying that the emails came from the domain that they claim to be from.

You can check your domain name, to see if DMARC has already been set up, by using this DMARC Check tool.

Contact us, to set up an appointment, to review your domain, and make sure DMARC is properly set up, so you don’t have trouble sending email to those providers beginning in 2024.

Temporarily disabled HTTP/2 on our Plesk hosting servers due to Rapid Reset vulnerability CVE-2023-44487

10/11/2023: HTTP/2 Rapid ResetWe have temporarily disabled HTTP/2 on our Plesk web hosting servers, due to a recently disclosed vulnerability in HTTP/2. Our servers will serve web pages using HTTP/1.1 until software updates containing the necessary mitigations are provided by Plesk, and Nginx. The effect of this change from HTTP/2 to HTTP/1.1 should, at most, be a slight reduction in website performance.

11/8/2023 Update: HTTP/2 has been re-enabled based on guidance from Plesk.

Check if you are a victim of the Qakbot Malware!

The Justice Department today announced a multinational operation involving actions in the United States, France, Germany, the Netherlands, the United Kingdom, Romania, and Latvia to disrupt the botnet and malware known as Qakbot and take down its infrastructure. [1]

On August 29th, 2023, the FBI provided Have I Been Pwned (HIBP) with 6.43M email addresses to help notify impacted victims of their exposure to the Qakbot malware. Anyone may check to see if their email address is included in the list of victims of the Qakbot malware via the HIBP notification service.

We recommend that everyone subscribes to the free notification service provided by Have I Been Pwned (HIBP) which can notify you if your email address is found in certain data breaches, including being in the Qakbot data.

Qakbot relied on compromised accounts to spread its malicious emails. If a receiver interacted with one of these emails, it is highly likely that their device became infected. As a result, they would have become part of the Qakbot botnet. [2]

If you find that your email address is in the Qakbot data, meaning your computer was probably infected with the malware, you should take several actions, including resetting your email password, and resetting any other passwords that were used on the infected computer (banking, shopping, etc.). Also, it’s possible your computer is infected with other additional malware, it should be scanned by a reputable antivirus/anti-malware product such as Malwarebytes or Windows Defender. Since Qakbot targets, among other things, banking/financial details, you should carefully review bank statements for unauthorized transactions and report any you find to your financial institution.
