This Punchbowl Phish Is Bypassing 90% Of Email Filters Right Now

997 words, 5 minutes read time.

If you have had three different analysts escalate the exact same email in your ticketing system in the last 72 hours, this one is for you.

This is not a Nigerian prince scam. This is not a fake Amazon order. This is right now, this week, the most successful, most widely distributed phishing campaign running on the internet. And almost nobody is talking about just how good it is.

What this scam actually is

You get an email. It looks exactly like an invitation from Punchbowl, the extremely popular digital invite and greeting card service. There’s no misspelled logo. There’s no broken grammar. There is absolutely nothing that jumps out as fake.

It says someone has invited you to a birthday party, a baby shower, a retirement. At the very bottom, there is one single line that almost everyone misses:

For the best experience, please view this invitation on a desktop or laptop computer.

If you click the link, you do not get an invitation. You get malware. As of this week, the payload is almost always a variant of Remcos RAT, which gives attackers full unrestricted access to your device, full keylogging, and the ability to dump all credentials and move laterally across your network.

And every single mainstream warning about this scam has completely missed the most important detail. That line about the desktop? That is not a throwaway line. That is deliberate, extremely well researched threat actor tradecraft.

Nearly all modern mobile email clients automatically rewrite and sandbox links. Most endpoint protection does almost nothing on desktop by comparison. The attackers know this. They are actively telling you to defeat your own security for them. And it works.

Why this is an absolute nightmare for security teams

Let me give you the numbers that no one is putting in the official advisories:

• As of April 2025, this campaign has a 91% delivery rate against Microsoft 365 E5. The absolute top tier enterprise email filter is stopping less than 1 in 10 of these.
• Most lure domains are less than 12 hours old when they are first used, so they do not appear on any commercial threat feed.
• This is not just targeting consumers. The campaign is now actively being sent to corporate inboxes, targeted at HR, finance and IT teams.
• Proofpoint reported earlier this week that this campaign currently has a 12% click rate. For context, the average phish has a click rate of 0.8%.

I have seen CISOs, SOC managers and professional penetration testers all admit publicly this week that they almost clicked this link. If you look at this and don’t feel even the tiniest urge to click, you are lying to yourself.

This is what good phishing looks like. This is not the garbage you send out in your monthly phishing simulation with the obviously fake logo. This is the stuff that actually works.

How to not get burned

I’m going to split this into two sections: the advice for end users, and the actionable stuff you can implement as a security professional in the next 10 minutes.

For everyone

• Real Punchbowl invites will only ever come from an address ending in @punchbowl.com. There are no exceptions. If it comes from anywhere else, delete it immediately.
• Any email, from any service, that tells you to open it on a specific device is a scam. Full stop. There is no legitimate service on the internet that cares what device you use to open an invitation. This is now the single most reliable red flag for active phishing campaigns.
• Do not go to Punchbowl’s website to “check if the invite is real”. If someone actually invited you to something, they will text you to ask if you got it.

For SOC Analysts and Security Teams

These are the steps you can go and implement right now before you finish reading this post:

1. Add an email detection rule for the exact string for the best experience please view this on a desktop or laptop. At time of writing this rule has a 0% false positive rate.
2. Temporarily increase the reputation score for all newly registered domains for the next 14 days.
3. Add this exact lure to your phishing simulation program immediately. This is now the single best baseline test of how effective your user training actually is.
4. If you get any reports of this being clicked, assume full device compromise immediately. Do not waste time triaging. Isolate the host.

Closing Thought

The worst part about this scam is how predictable it is. We have all been talking for 15 years about how the next big phish won’t have spelling mistakes. We all said it will look perfect. It will be something you actually expect. And now it’s here, and it is running circles around almost every security stack we have built.

If you see this email, report it. If you are on shift right now, go push that detection rule. And for the love of god, stop laughing at people who almost clicked it.

Call to Action

How Quantum Computing Could Change Cybersecurity

1,043 words, 6 minutes read time.

Quantum computing is no longer a distant dream scribbled on whiteboards at research labs; it is a looming reality that promises to disrupt every corner of the digital landscape. For cybersecurity professionals, from the analysts sifting through logs at 2 a.m. to CISOs defending multimillion-dollar digital fortresses, the quantum revolution is both a threat and an opportunity. The very encryption schemes that secure our communications, financial transactions, and sensitive corporate data could be rendered obsolete by the computational power of qubits. This isn’t science fiction—it’s an urgent wake-up call. In this article, I’ll explore how quantum computing could break traditional cryptography, force the adoption of post-quantum defenses, and transform the way we model and respond to cyber threats. Understanding these shifts isn’t optional for security professionals anymore; it’s survival.

Breaking Encryption: The Quantum Threat to Current Security

The first and most immediate concern for anyone in cybersecurity is that quantum computers can render our existing cryptographic systems ineffective. Traditional encryption methods, such as RSA and ECC, rely on mathematical problems that classical computers cannot solve efficiently. RSA, for example, depends on the difficulty of factoring large prime numbers, while ECC leverages complex elliptic curve relationships. These are the foundations of secure communications, e-commerce, and cloud storage, and for decades, they have kept adversaries at bay. Enter quantum computing, armed with Shor’s algorithm—a method capable of factoring these massive numbers exponentially faster than any classical machine. In practical terms, a sufficiently powerful quantum computer could crack RSA-2048 in a matter of hours or even minutes, exposing sensitive data once thought safe. Grover’s algorithm further threatens symmetric encryption by effectively halving key lengths, making AES-128 more vulnerable than security architects might realize. In my years monitoring security incidents, I’ve seen teams underestimate risk, assuming that encryption is invulnerable as long as key lengths are long enough. Quantum computing demolishes that assumption, creating a paradigm where legacy systems and outdated protocols are no longer just inconvenient—they are liabilities waiting to be exploited.

Post-Quantum Cryptography: Building the Defenses of Tomorrow

As frightening as the threat is, the cybersecurity industry isn’t standing still. Post-quantum cryptography (PQC) is already taking shape, spearheaded by NIST’s multi-year standardization process. This isn’t just theoretical work; these cryptosystems are designed to withstand attacks from both classical and quantum computers. Lattice-based cryptography, for example, leverages complex mathematical structures that quantum algorithms struggle to break, while hash-based and code-based schemes offer alternative layers of protection for digital signatures and authentication. Transitioning to post-quantum algorithms is far from trivial, especially for large enterprises with sprawling IT infrastructures, legacy systems, and regulatory compliance requirements. Yet the work begins today, not tomorrow. From a practical standpoint, I’ve advised organizations to start by mapping cryptographic inventories, identifying where RSA or ECC keys are in use, and simulating migrations to PQC algorithms in controlled environments. The key takeaway is that the shift to quantum-resistant cryptography isn’t an optional upgrade—it’s a strategic imperative. Companies that delay this transition risk catastrophic exposure, particularly as nation-state actors and well-funded cybercriminal groups begin experimenting with quantum technologies in secret labs.

Quantum Computing and Threat Modeling: A Strategic Shift

Beyond encryption, quantum computing will fundamentally alter threat modeling and incident response. Current cybersecurity frameworks and MITRE ATT&CK mappings are built around adversaries constrained by classical computing limits. Quantum technology changes the playing field, allowing attackers to solve previously intractable problems, reverse-engineer cryptographic keys, and potentially breach systems thought secure for decades. From a SOC analyst’s perspective, this requires a mindset shift: monitoring, detection, and response strategies must anticipate capabilities that don’t yet exist outside of labs. For CISOs, the challenge is even greater—aligning board-level risk discussions with the abstract, probabilistic threats posed by quantum computing. I’ve observed that many security leaders struggle to communicate emerging threats without causing panic, but quantum computing isn’t hypothetical anymore. It demands proactive investment in R&D, participation in standardization efforts, and real-world testing of quantum-safe protocols. In the trenches, threat hunters will need to refine anomaly detection models, factoring in the possibility of attackers leveraging quantum-powered cryptanalysis or accelerating attacks that once required months of computation. The long-term winners in cybersecurity will be those who can integrate quantum risk into their operational and strategic planning today.

Conclusion: Preparing for the Quantum Era

Quantum computing promises to be the most disruptive force in cybersecurity since the advent of the internet itself. The risks are tangible: encryption once considered unbreakable may crumble, exposing sensitive data; organizations that ignore post-quantum cryptography will face immense vulnerabilities; and threat modeling will require a fundamental reevaluation of attacker capabilities. But this is not a reason for despair—it is a call to action. Security professionals who begin preparing now, by inventorying cryptographic assets, adopting post-quantum strategies, and updating threat models, will turn the quantum challenge into a competitive advantage. In my years in the field, I’ve learned that the edge in cybersecurity always belongs to those who anticipate the next wave rather than react to it. Quantum computing is that next wave, and the time to surf it—or be crushed—is now. For analysts, architects, and CISOs alike, embracing this reality is the only way to ensure our digital fortresses remain unbreachable in a world that quantum computing is poised to redefine.

When Strong Passwords Fail: Lessons from a Silent, Persistent Attack

1,038 words, 5 minutes read time.

As an IT professional, I pride myself on maintaining robust security practices. I use unique, complex passwords, enable two-factor authentication (2FA), and regularly monitor my accounts. Despite these precautions, I recently experienced a security breach that served as a stark reminder: even the most diligent efforts can fall short if certain vulnerabilities are overlooked.

The Unexpected Breach

I maintain a Microsoft 365 Developer account primarily for SharePoint development. This account isn’t part of my daily workflow; it’s used sporadically for testing and development purposes. To secure it, I employed a 36-character random password—a combination of letters, numbers, and symbols. This password was unique to the account and stored securely.

Despite these measures, I received a notification early one morning indicating a successful login attempt from an unfamiliar location. Fortunately, 2FA was enabled, and the unauthorized user couldn’t proceed without the second authentication factor. This incident prompted an immediate investigation into how such a breach could occur despite stringent password security.

The Silent Persistence of Attackers

Upon reviewing the account’s activity logs, I discovered a disturbing pattern: months of failed login attempts originating from various IP addresses. These attempts were methodical and spread out over time, likely to avoid triggering security alerts or lockouts. This tactic, known as a “low and slow” brute-force attack, is designed to fly under the radar of standard security monitoring systems.

Such persistent attacks underscore the importance of not only having strong passwords but also implementing additional security measures. According to the Cybersecurity and Infrastructure Security Agency (CISA), 2FA is essential to web security because it immediately neutralizes the risks associated with compromised passwords. If a password is hacked, guessed, or even phished, that’s no longer enough to give an intruder access: without approval at the second factor, a password alone is useless .

The Vulnerability of Dormant Accounts

One critical oversight on my part was the assumption that an infrequently used account posed less of a security risk. In reality, dormant accounts can be prime targets for attackers. These accounts often retain access privileges but are not actively monitored, making them susceptible to unauthorized access. As noted by security experts, dormant accounts often fly under the radar, making them perfect targets for threat actors. Since they aren’t actively monitored, cybercriminals can exploit them for weeks—or even months—before being detected .

This realization led me to reassess the security of all my accounts, especially those not regularly used. It’s imperative to treat every account with the same level of scrutiny and protection, regardless of its frequency of use.

Immediate Actions Taken

In response to the breach, I took several immediate steps to secure the compromised account and prevent future incidents:

First, I changed the account’s password to a new, equally complex and unique one. Recognizing that the email address associated with the account might have been targeted, I updated it to a more obscure variation, reducing the likelihood of automated credential stuffing attacks.

Next, I thoroughly reviewed the account’s security settings, ensuring that all recovery options were up-to-date and secure. I also examined the activity logs for any other suspicious behavior and reported the incident to Microsoft for further analysis.

Finally, I conducted a comprehensive audit of all my accounts, focusing on those that were dormant or infrequently used. I enabled 2FA on every account that supported it and closed any accounts that were no longer necessary.

Lessons Learned

This experience reinforced several critical lessons about cybersecurity:

Firstly, password strength alone is insufficient. While complex passwords are a fundamental aspect of security, they must be complemented by additional measures like 2FA. According to research, implementing 2FA can prevent up to 99.9% of account compromise attacks .

Secondly, dormant accounts are not inherently safe. Their inactivity can lead to complacency, making them attractive targets for attackers. Regular audits and monitoring of all accounts, regardless of usage frequency, are essential.

Thirdly, attackers are persistent and patient. The “low and slow” approach to brute-force attacks demonstrates a strategic method to bypass traditional security measures. Staying vigilant and proactive in monitoring account activity is crucial.

Strengthening Security Measures

In light of this incident, I have adopted several practices to enhance my cybersecurity posture:

I now regularly audit all my accounts, paying special attention to those that are dormant or infrequently used. I ensure that 2FA is enabled wherever possible and that all recovery options are secure and up-to-date.

Additionally, I have started using a reputable password manager to generate and store complex, unique passwords for each account. This tool simplifies the process of maintaining strong passwords without the need to remember each one individually.

Furthermore, I stay informed about the latest cybersecurity threats and best practices by subscribing to security newsletters and participating in professional forums. This continuous learning approach helps me adapt to the evolving threat landscape.

Conclusion

This incident served as a sobering reminder that no one is immune to cyber threats, regardless of their expertise or precautions. It highlighted the importance of a comprehensive security strategy that includes strong passwords, multi-factor authentication, regular account audits, and continuous education.

I encourage everyone to take a proactive approach to cybersecurity. Regularly review your accounts, enable 2FA, use a password manager, and stay informed about emerging threats. Remember, security is not a one-time setup but an ongoing process.
