Wine not? Because this malware is no joke. Cozy Bear’s latest cyber-attack has us swirling red flags instead of Merlot.
In this publication, we're diving into a sophisticated scam that combines digital espionage, malware, and social engineering—all under the cover of a classy-sounding wine tasting invitation.
A notorious Russian hacking group is using fake diplomatic events to lure victims and quietly install powerful malware.
The malware, called GrapeLoader, is being deployed through phishing emails disguised as wine tasting invites from what looks like a European foreign ministry. Behind this charming bait? APT29—yes, the same crew behind the SolarWinds attack.
How It Works:
- Tempting Email Invite: Victims receive what looks like an official wine tasting invitation from a foreign affairs ministry.
- Malicious Attachment: The invite contains a ZIP file with three components—wine.exe (PowerPoint executable), a dummy DLL, and GrapeLoader.
- Stealthy Execution: Opening wine.exe triggers a chain reaction that loads GrapeLoader, copies files to the system, modifies the registry, and achieves persistence.
- Silent Data Harvesting: The malware quietly collects system info and waits for further instructions from its command server.
- Advanced Evasion: It disguises its presence with techniques like in-memory string encryption and anti-analysis measures.
The email even redirects users to a real foreign ministry site if it detects something suspicious—like being opened in the wrong time zone or by an analysis tool.
Who’s Targeted:
- Embassies and Foreign Ministries in Europe
- Diplomatic staff and government officials
- Any system with geopolitical intelligence value
This attack isn’t your average scam—it’s precision-engineered for political and espionage-related targets.
Real-Life Example:
Since January 2025, Check Point Research has been tracking this wave of attacks. A diplomatic mission in Europe unknowingly activated GrapeLoader after opening a wine event invite. What seemed like a social gesture turned into a full-blown espionage operation.
“GRAPELOADER refines WINELOADER’s anti-analysis techniques while introducing more advanced stealth methods,” Check Point reported.
Why You Should Care:
Even if you're not working in a consulate, this type of malware is a blueprint for future scams—blending believable stories with advanced tech. It highlights how social engineering and AI-driven malware are now working hand in hand. If cybercriminals can fool diplomats, the average user is definitely at risk.
Whether you’re in government, business, or just checking your email, stealthy threats like this could compromise:
- Sensitive documents
- Communication logs
- National security data
- Personal and financial information
How to Protect Yourself:
- Don’t download files from unknown or suspicious emails—even if they seem official.
- Check the sender’s address carefully for any inconsistencies or spoofed domains.
- Disable auto-running executable files from downloaded archives.
- Use behavior-based antivirus tools that monitor system changes, not just file signatures.
- Update your security patches regularly—many of these threats exploit unpatched vulnerabilities.
Quick Tips & Updates:
Quick Tip #1: Did you know? Modern malware often only decrypts strings in memory and deletes them immediately—making it invisible to many traditional detection tools.
Pro Tip: If you're unsure about an attachment, upload it to a sandbox analysis tool (like VirusTotal) before opening. Better safe than sorry.
🍷 Summary in a Sip:
- Fake wine event invite → Malware infection
- Russian APT29 behind it
