Threat actors bypass DKIM authentication checks with the DKIM replay attack technique. This allows them to attain a copy of a valid email and replay it with additional or replaced From, To, or Subject headers. As the original DKIM signature is valid, the replayed version also passes the DKIM authentication checks. This way, even phishing and spoofing emails land in the recipients’ inboxes instead of spam folders.
Recently, Microsoft users received data breach notification emails, which, however, were marked as spam by Microsoft’s own security tools.
Email authentication has become a non-negotiable standard for companies and governments, as it prevents phishing, spoofing, ransomware, and other email-based cyberattacks. Email authentication protocols also raise alerts for modified email contents as these changes indicate tampering done by threat actors.
Here we are back again with cybersecurity’s latest covering the news that shook the world this week. We’ll take a look at Chinese hackers taking over SOHO routers for attacks, how the US DoJ shut down Russian bot accounts on X, the new passkeys for Google account protection, the Fujitsu data breach, and the compromise of personal and healthcare information of the City of Philadelphia. Stay tuned!
Google has always prioritized user safety and has designed the Google Critical Security Alert to warn users whenever a threat actor or unauthorized person tries to access your Google account. This security feature also alerts you if there is a login to your account from a new or unrecognized device, allowing you to deny access if you don’t recognize the device. You receive a notification on your primary device (in which the particular Google account is logged in), where you have to click on either of the options – ‘Yes, it’s me’ or ‘No, secure account.’ You may also receive this notification via email.
Email authentication protocols like the Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are considered to be robust mechanisms to protect against cybersecurity threats such as spoofing and phishing. This is when you are sending emails from your domain, but when it comes to forwarding emails, these protocols fall short.
DMARC helps prevent spoofed emails from bypassing spam filtering, but it’s just one part of a broader anti-spam strategy. Not all DMARC reports are equal; some show detailed recipient responses, while others only indicate success or failure. Understanding why a message failed is as important as knowing if it did.
Welcome back to our weekly bulletin, where we bring you the latest cybersecurity information so you can stay safe against the latest attacks and malicious campaigns. We’ll share details about the new Brain Cipher ransomware, how info stealers could track users linked to child abuse sites, the corporate attack on Team Viewer, the story of a scorned employee stealing patient healthcare data, and the latest crypto drainer phishing attack on Ethereum. Stay tuned!
A DKIM record is a DNS record in the TXT format that includes a public key that is used by recipients’ mail servers to verify the legitimacy of emails they receive from your domain. A standard DKIM record has a name, version, key type, and public key. Some domain owners think that creating a DKIM record requires hardcore technical expertise, but that’s not true, especially when it comes to generating a basic DKIM record. You just need to be an average tech user, and you will be able to create a DKIM record on your own.
