State-sponsored hacktivism is on the rise. Script kiddies use pre-existing scripts while others employ highly sophisticated tactics using diverse tools and resources. Attackers are scouring GitHub for sensitive information on GitHub and trying to steal critical information from repositories. Security breaches happen when they gain unauthorized access to the source code. This week, we’re reviewing a series of the latest cybersecurity incidents by closely analyzing their attack trends and threat vectors. We’ll also discuss how a significant cryptocurrency exchange organization was the victim of a massive crypto attack and explore how the FatalRAT malware targeted organizations across APAC. Below is a summary of the latest findings.
Email marketing is the most effective digital marketing strategy. That’s because its ROI (return on investment) is the highest—3600% to 4200%.
But that’s not for any ordinary email marketing campaign. For that much ROI, your emails have to be highly personalized. In different studies, 82% of marketers reported an increase in their open rates with personalization.
The role of canonicalization in preventing email breakage in DKIM
by DuoCircle
DKIM policy secures your email communications by detecting any kind of tampering or alterations during the transit. However, the journey from your outbox to a receiving inbox is an intricate one. Since emails get delivered super quick, we fail to notice the minor changes that take place during the process. The mail systems may lead to certain minor changes in the email content (line breaks, case differences, whitespace, and so on). Even though the changes may not appear to be too major, they can affect the integrity of the email, thereby resulting in DKIM failure. In order to avoid these instances of false negatives, you must focus on canonicalizing your emails.
Is BIMI just an authentication protocol? 6 Reasons it’s more than that!
by DuoCircle
Your emails are not simply a communication channel; they are a representation of your brand, its trustworthiness, identity, and professionalism. Similarly, Brand Indicators for Message Identification (BIMI) is more than just an authentication protocol.
Cybersecurity threats are rapidly evolving at an unprecedented rate, making cybersecurity more critical than ever. This week, we uncovered a new malware targeting macOS users through fake browser updates and a stealthy cyberattack exploiting Windows utilities to evade detection. We will also explore how hackers deploy payment skimmers using hidden image tags, as well as discover how the latest cyber espionage campaigns target big industries and international corporations. Lastly, we will cover the news highlighting recent data breaches affecting thousands of individuals and organizations across the globe.
There is no doubt that DMARC is deployed to prevent phishing and spoofing emails; however, misconfigured DMARC records are synonymous with exploitable vulnerabilities. DMARC is implemented in tandem with SPF and DKIM. This email authentication structure compensates for the drawbacks of SPF and DKIM. SPF’s drawback is that it is highly likely to break when emails are forwarded; this means when someone forwards a legitimate email, the receiving server will either mark it as spam or reject it. DKIM’s drawback is that it triggers false positives because of inadvertent message modifications.
What is the role of cryptography in the healthcare industry?
by DuoCircle
Here’s a bitter reality: Cyberattackers leave no individual or sector behind.
We know that data breaches and cyberattacks have become a reality today— thanks to technological evolution. However, the actual issue arises when critical services like healthcare become the target of malicious activities.
Massive Cyber Attack, ClickFix Deploys RAT, Hacker Group Attacks – Cybersecurity News [February 10, 2025]
by DuoCircle
Cybercriminals nowadays are getting smarter and adapting social engineering and ransomware techniques to attack their targets. This week, we’re covering a series of critical attacks that smartly leveraged the use of BotNet, affecting around 2.8 million devices. Also, we will uncover how social engineering attacks were executed to run unintended malicious PowerShell commands.
DKIM works using encryption techniques and digital signatures that help the sender’s server transparently sign outgoing emails so that the recipient’s server can verify if the content has been altered in transit. DKIM is highly sensitive to message modifications; even the slightest difference between the content the sender sent and the recipient received causes DKIM verification to fail.
What are the most important email security protocols, and how do they protect your communications?
by DuoCircle
If you send marketing email campaigns to your clients almost every day, you will know that email is one of the key channels to connect with your audience. But what you might not realize is that it is also the most vulnerable channel that lets cybercriminals in and leaves your entire ecosystem exposed to phishing, spoofing attacks, and data breaches.
The key differences between Sender Policy Framework and Sender ID
by DuoCircle
The primitive version of SMTP (Simple Mail Transfer Protocol) didn’t have a feature to verify the email sender’s authenticity, leaving room for phishing and spoofing instances. Over time, emails became one of the most exploitable attack vectors. It was easier for threat actors to modify the ‘From’ field in an email to impersonate banks, governments, and well-known brands. They would send millions of potentially fraudulent emails each day, urging recipients to ‘reset their password’ or ‘verify their account,’ leading to credential theft.
Zip Flaw Exploited, Meta Confirms Spyware, ENGlobal Ransomware Outage – Cybersecurity News [February 03, 2025]
by DuoCircle
Cyber threats are becoming more sophisticated with each day passing by, attacking individuals and businesses unpredictably. This week’s security news covers news pieces directly curated from authentic sources. We will discuss how a new exploit in 7-Zip allowed attackers to bypass Windows security and how Meta identified a spyware attack on 90 journalists and activists.
Everything you need to know about setting up email authentication on Mailchimp!
by DuoCircle
If you want your emails to reach your subscribers’ inboxes without any hassle, setting up email authentication for your authorized domain is something you can’t afford to ignore. Domain authentication enables you to send out your emails to the right inbox. It also enables you to maintain your subscriber base and grow them eventually by keeping them actively engaged.
How does DKIM alignment affect overall DMARC compliance?
by DuoCircle
DMARC is based on SPF and DKIM results. For an email to pass the DMARC checks, it has to pass at least one of the protocols and have alignment with the domain in the ‘From’ header.
Data accuracy: What is it, and how can authentication protocols help?
by DuoCircle
Every organization thrives on data— whether it is your customers’ details, financial transactions, or some kind of operational records. This data not only tells you about what is going on in your organization but is also crucial to making strategic decisions or even undertaking everyday operations. So, data is essentially the backbone of your organization. But remember, this data is only valuable when it is accurate. Any discrepancy in the information can have a domino effect on basically everything that is going on in your company.

Learning to leverage Google Postmaster tools the right way to monitor the performance of your IPs
by DuoCircle
A late 2023 poll found that over half of marketing professionals saw their email marketing ROI double, proving why email has remained a powerful tool since its launch in the 1970s. Now that more brands rely on email marketing for their brand growth, staying relevant in recipients’ inboxes is a challenge. The engagement rate shows positive growth only if your content is meaningful for the receivers. It’s all about figuring out what type of audience likes what and serving them exactly that. (more…)
How to discover source owners using the ‘envelope_to’ domain?
by DuoCircle
An envelope_to domain is the domain of the recipient’s email address. So, if we shoot an email to someone@sample.com, then sample.com is the envelope_to domain. Now, let’s quickly recall what RUA reports are to understand the concept fully. So, RUA or aggregate DMARC reports are XML-based reports that are sent by the receiving server to the email address specified in the DMARC policy. It includes details like-
Have you already implemented DMARC but still think there’s a possibility of phishers slipping your email ecosystem and sending fraudulent emails on your behalf?
