"- We discovered a new malware family which consists of a modular loader and an array of unique memory-resident components, all of which bridge multiple programming languages to avoid detection.
- By reverse engineering the malware and emulating the command-and-control protocol, we were able to lure the threat actors into attempting a hands-on-keyboard attack against our fake network, enabling us to obtain a significant portion of their tooling.
- The original attack chain was distributed by a Microsoft Teams phishing technique in which the attacker posed as a member of the company’s IT helpdesk.
- The malware attempts to phish the user’s system login credentials by creating a fake lock screen. It then loads a network tunneling module to enable the threat actors to log into internal and external company systems via the infected user’s machine."

SynkLoader: when you throw in everything but the kitchen sink
A sophisticated modular loader utilizing multiple programming languages to evade detection has been discovered. The attack begins with Microsoft Teams phishing where attackers impersonate IT helpdesk personnel, convincing targets to install a fake PowerShell cleaner via MSI installer. The malware deploys memory-resident components bridging Python, C#, C++, and PowerShell to profile systems, establish persistence via scheduled tasks, and deploy a fake Windows lock screen to phish user credentials. Additional modules include a reverse proxy for network tunneling, enabling threat actors to access internal corporate systems using compromised credentials, plus remote shell and VNC capabilities for hands-on-keyboard attacks. The elaborate multi-stage infection chain suggests potential ransomware operations or initial access brokering.

Teams is so bad and illuminates a #microsoft pathology. I'm a guest on a call and forced to use #MicrosoftTeams It just grabbed a random profile on my desktop - there's no guest option, no opt-in, they just grab it. So I'm on a call right now **as two of my cats** (who own the family calendar). Microsoft think they might even have found the #catsofMastodon #linkedin account where Alex and Prudence have probably been congratulating one another on recent promotions.

Microsoft Teams Vishing Campaign Leads to Chaos Ransomware Deployment
STAC4749 is a financially motivated Teams-based vishing campaign in which attackers impersonate IT support to gain remote access through Quick Assist or RemSupp. They then deploy malware, establish persistence, move laterally, and ultimately deploy Chaos ransomware.

Helpdesk Hijackers: Teams Vishing, Quick Assist, and GoGRPC Backdoor
Since January 2026, a threat actor likely functioning as an initial access broker for ransomware operations has been targeting organizations through Microsoft Teams vishing attacks. Attackers impersonate IT helpdesk staff to convince victims to initiate Quick Assist remote sessions. Following initial compromise, PowerShell scripts deploy a Go-based backdoor called GoGRPC, which exists in four distinct variants: Lep, Giver, Pet, and Kind. These variants communicate with command-and-control infrastructure using gRPC over HTTP/2, an uncommon approach that helps blend malicious traffic with legitimate communications. Additional tools observed include BlindDoor backdoor, RevSocket and PyGRPC SOCKS proxies, S3Siphon data exfiltration utility, and RSOX Rust-based proxy relay. Recent campaigns show increased sophistication and selectivity, with heightened focus on corporate environments through enhanced PowerShell scripts capable of antivirus detection, domain controller fingerprinting, and system reconnaissance b...

Email threat landscape: Q2 2026 trends and insights
During Q2 2026, Microsoft detected approximately 7.6 billion email-based phishing threats, with monthly volumes declining from 2.7 billion in April to 2.4 billion in June. The quarter was significantly shaped by the downstream effects of Microsoft's Digital Crimes Unit disruption of the Tycoon2FA phishing-as-a-service platform in March, resulting in a 92% decline in associated phishing volume. QR code phishing attacks peaked at 18.7 monthly attacks in March before declining 48% by June, while CAPTCHA-gated phishing fell 81% from its March high. Credential phishing remained the dominant objective, accounting for 94-96% of all payload-based attacks. Business email compromise activity returned to historical norms after an anomalous April surge. Microsoft Teams-based threats grew substantially, with weekly malicious call attempts reaching nearly ten times the mid-2025 baseline by quarter end.

[Edit: Falscher Alarm, Microsoft ist unschuldig. Tatsächlich stammt das Bild doch von der Seite: es ist dort zwar nicht zu sehen, aber im Quelltext als Teaserbild für Social Media angegeben. Sorry dass ich das nicht erst prüfte!]
Was sollte eine Chat-Software tun, wenn für eine Linkvorschau kein Bild auf der Webseite gefunden werden kann? Richtig, natürlich selbst ein Bild generieren.
MS Teams macht das genau richtig. Sarkasmus Ende.
