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

If this breakdown helped you think a little clearer about the threats out there, don’t just click away. Subscribe for more no-nonsense security insights, drop a comment with your thoughts or questions, or reach out if there’s a topic you want me to tackle next. Stay sharp out there.

Zobacz jak polować na włamywaczy i na czym polega obsługa incydentów w SOC

W piątek 17 września, o godzinie 19:00 robimy lajwa pt. “Jak naprawdę wygląda praca w SOC“. Zapisać może się każdy, wystarczy kliknąć na poniższy przycisk:

Zapisz się, nawet jeśli ten termin Ci nie pasuje, bo każdy kto się zapisze, otrzyma od nas wieczysty dostęp do nagrania po zakończeniu transmisji. Możesz też otrzymać certyfikat potwierdzający udział.
Threat hunting, w ramach którego poluje się na cyberprzestępców, to bardzo ciekawa praca. Właśnie tym zajmują się pracownicy tzw. SOC-ów (ang. Security Operations Center). Na lajwie pokażemy z jakich narzędzi korzystają, aby wykrywać zagrożenia i obsługiwać incydenty w małych i dużych firmach. Część z tej wiedzy przyda Ci się nie tylko w firmie — możesz ją wykorzystać do ochrony domowej sieci. A jeśli przeszło Ci przez myśl, żeby zmienić pracę i dołączyć do zespołu SOC w jakiejś firmie (albo dopiero zaczynasz swoją karierę w IT), to już w ogóle nasz piątkowy LIVE będzie dla Ciebie idealnym drogowskazem, jak to zrobić i na co uważać.
Co dokładnie pokażemy?
W trakcie spotkania zobaczysz 2 demonstracje:

‍ Jak wyglada analiza przykładowego incydentu?
‍ Jak wygląda przykładowy Threat Hunting

A oprócz tego pokażemy też:

narzędzia używane w profesjonalnych SOC-ach wraz ze szczerym omówieniem wad i zalet (Splunk, Wazuh, Elastic, MITRE, OpenCTI, MISP),
różne stanowiska w SOC-ach oraz to, co powinieneś umieć, aby rozpocząć na nich pracę,
jak zbudować domowy SOC,
gdzie w SOC-ach jest miejsce dla AI i agentów,

Będzie też sekcja Q&A z Michałem Garcarzem, który ma 30 lat doświadczenia w obszarze cyberbezpieczeństwa, a od ponad 10 lat buduje i nadzoruje różne SOC. [...]

DXC i 7AI wprowadzają autonomicznych agentów AI do cyberbezpieczeństwa. Koniec z ręczną analizą alertów?

DXC Technology, globalny dostawca usług IT, oraz firma 7AI, specjalizująca się w tzw. agentach AI, ogłosiły strategiczne partnerstwo.

Jego owocem jest nowa usługa DXC Agentic Security Operations Center (SOC), która wykorzystuje autonomiczne, inteligentne boty do wykrywania, analizy i neutralizowania cyberzagrożeń. Rozwiązanie ma skrócić czas reakcji, obniżyć koszty i zwiększyć skalę ochrony firm.

Nowo utworzone centrum bezpieczeństwa odchodzi od tradycyjnego modelu, w którym analitycy ręcznie przetwarzają alerty. Zamiast tego, zadania te przejmują inteligentni agenci AI, którzy samodzielnie analizują potencjalne zagrożenia i reagują na incydenty. Jak zapowiada Maciej Tomczyk, dyrektor zarządzający DXC Technology Poland, usługa będzie dostępna dla klientów na całym świecie, w tym również w Polsce, oferując „większą szybkość działania, sprawniejsze wykrywanie i reagowanie na incydenty bezpieczeństwa”.

Już ponad połowa firm korzysta z agentów AI. Raport Google Cloud pokazuje, gdzie zwrot z inwestycji jest największy

Kluczem do działania platformy jest innowacyjna technologia „Dynamic Reasoning” opracowana przez 7AI. Pozwala ona autonomicznym agentom ustalać w czasie rzeczywistym, jak badać nowe, nawet wcześniej nieznane zagrożenia, bez potrzeby korzystania z gotowych scenariuszy. Dzięki temu DXC Agentic SOC eliminuje opóźnienia związane z ręczną obsługą, skracając czas potrzebny na zbadanie zagrożenia – który dotychczas wynosił od 30 minut do 2,5 godziny – i redukując liczbę fałszywych alarmów.

Partnerstwo opiera się na synergii obu firm. DXC wnosi swoją globalną skalę działania, w tym obsługę setek klientów i przetwarzanie 4,5 miliona zagrożeń dziennie, co tworzy ogromne środowisko danych do trenowania AI. 7AI dostarcza natomiast swoją przełomową platformę. Według danych 7AI, jej technologia pomogła już zaoszczędzić klientom ponad 224 000 godzin pracy analityków, co przekłada się na ponad 11,2 mln dolarów odzyskanej produktywności. Prognozy na rok 2025 zakładają oszczędności przekraczające 100 milionów dolarów.

Cisco udostępnia otwarty model AI dla cyberbezpieczeństwa. Ma być skuteczniejszy niż ChatGPT
