Behind the Refund: From GST Phishing to Remcos RAT Through a Multi-Stage .NET Infection Chain

A sophisticated phishing campaign targeting Indian businesses and taxpayers leverages GST-related themes to distribute Remcos RAT through a multi-stage .NET framework. Threat actors impersonate Government of India GST communications using fraudulent refund notifications with convincing ARN references. The attack chain begins with a malicious RAR archive containing a .NET executable that employs bitmap-based payload concealment techniques. Through successive stages including Windows Health Optimizer Plus.dll and perfgurd.dll, the malware deploys Remcos RAT entirely in memory, establishing persistence via PowerShell scripts and registry modifications. Command-and-control infrastructure utilizes dynamic DNS services with randomized subdomains under aofmokighoig.hath.network. The deployed Remcos RAT enables remote command execution, keylogging, credential harvesting, file manipulation, and comprehensive system reconnaissance capabilities, representing a financially motivated cybercrime operation specifically t...

Novel Starland RAT and bespoke WLDR C2 implant deployed in financially motivated campaign

A sophisticated Russian-speaking financially motivated adversary designated UAT-11795 has been conducting malicious operations targeting users in the United States and Europe since June 2025. The campaign delivers a Python-based remote access tool called Starland RAT and a PowerShell-based command-and-control memory implant known as the WLDR agent. The actor distributes trojanized installers disguised as legitimate software including MobaXterm, WebEx, Zoom, DBeaver, and FACEIT through likely ClickFix social engineering techniques. The operation targets victims' credentials and cryptocurrency wallet assets while establishing persistent connections for additional payload delivery. Alternative payloads include CastleStealer and Remcos RAT. The infrastructure utilizes distributed staging and C2 domains, Telegram bots for notifications, and a Polygon smart contract as a fallback mechanism for C2 domain resolution. The WLDR agent features encrypted beaconing, task queuing, and a Runspace execution engine for exe...

AsyncRAT and Remcos Delivered in Multi-Stage Phishing Campaign

A widespread phishing campaign distributing AsyncRAT and Remcos RATs has been observed targeting organizations across manufacturing, media, professional services, agriculture, and chemical industries globally. The attack leverages malicious Excel spreadsheets sent via emails impersonating business communications like purchase orders and payment advice. When macros are enabled, VBA code retrieves HTA payloads through URL shorteners and Cloudflare Workers infrastructure. The multi-stage infection chain employs heavy obfuscation including Base64 encoding, steganography in PNG files, and character substitution. The campaign intensified during June 2026, affecting organizations across Europe, Asia-Pacific, and the Americas. Infrastructure includes distinctive HTA naming conventions using concatenated positive English words. The operation likely uses automation for payload generation and may leverage LLMs for development efficiency.

A Multi-Stage Steganographic Loader Campaign Deploying Diverse Payloads Globally

A sophisticated phishing campaign was identified distributing multiple malware families through a multi-stage loader utilizing steganography and fileless techniques. The infection chain begins with archive attachments containing files disguised as financial documents, primarily targeting Indian organizations using names related to GST, NEFT, RTGS, and IMPS transactions. The loader employs in-memory execution to avoid disk-based artifacts and uses embedded .NET Bitmap objects to conceal payloads. Various malware families have been deployed including Remcos RAT, Agent Tesla, MassLogger, Phantom Stealer, Dark Cloud, Red Line Stealer, Snake keyloggers, Formbook, and xworm. The final payloads establish persistence through registry Run keys, perform process hollowing, steal browser credentials, record audio and webcam, and exfiltrate data to command-and-control infrastructure. The campaign exhibits characteristics of a loader-as-a-service operation serving multiple threat actors globally.

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.

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.

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:
