Russian state-sponsored hacking group APT29, also known as Cozy Bear or Midnight Blizzard, is actively targeting European diplomatic entities with a sophisticated phishing campaign that began in January 2025. The threat actors are using deceptive emails disguised as invitations to wine-tasting events, enticing recipients to download a malicious ZIP file. The ZIP file contains a PowerPoint executable ("wine.exe") and two hidden DLL files, one of which is a malware loader dubbed GRAPELOADER. This campaign appears to be focused on targeting European diplomatic entities, including non-European countries’ embassies located in Europe.
GRAPELOADER is a newly observed initial-stage tool used for fingerprinting, persistence, and payload delivery. Once executed, GRAPELOADER establishes persistence by modifying the Windows registry, collects basic system information such as the username and computer name, and communicates with a command-and-control (C2) server to fetch additional malicious payloads. The malware copies the contents of the malicious zip archive to a new location on the disk, achieves persistence by modifying the Windows registry’s Run key, ensuring that wine.exe is executed automatically every time the system reboots. In addition to GRAPELOADER, a new variant of WINELOADER, a modular backdoor previously used by APT29, has been discovered and is likely being used in later stages of the attack. GRAPELOADER employs advanced techniques to avoid detection, such as masking strings in its code and only decrypting them briefly in memory before erasing them. These recent attacks use a new technique aimed at abusing legitimate Microsoft OAuth 2.0 Authentication workflows. The attackers are impersonating officials from various European nations, and in one instance leveraged a compromised Ukrainian Government account. Recommended read:

Russian state-sponsored espionage group Midnight Blizzard, also known as APT29 or Cozy Bear, is conducting a spear-phishing campaign targeting European diplomatic organizations. Check Point Research has been observing this sophisticated operation, which began in January 2025 and employs advanced techniques to target government officials and diplomats across Europe. The threat actors are impersonating a major European foreign affairs ministry to send deceptive emails inviting targets to wine-tasting events. This campaign, leveraging custom malware, aims to compromise diplomatic entities, including embassies of non-European countries.
The campaign introduces a previously unseen malware loader called GrapeLoader, along with a new variant of the Wineloader backdoor. The phishing emails, sent from domains like 'bakenhof[.]com' or 'silry[.]com,' contain malicious links that, under specific conditions, initiate the download of a ZIP archive named 'wine.zip'. If the targeting conditions are not met, victims are redirected to the legitimate website of the impersonated ministry, reducing suspicion. This mirrors a previous Wineloader campaign, indicating a continued focus on European diplomacy by APT29. Once executed via DLL sideloading, GrapeLoader collects host information, establishes persistence by modifying the Windows Registry, and contacts a command-and-control server. The use of in-memory execution is an advanced evasion technique to complicate detection. The objective of the campaign is likely espionage, given APT29's history of targeting high-profile organizations, including government agencies and think tanks, and its association with the SolarWinds supply chain attack.

A new phishing campaign called 'PoisonSeed' has emerged, posing a significant cybersecurity threat by targeting customer relationship management (CRM) platforms and bulk email service providers. The campaign leverages compromised credentials to distribute emails containing cryptocurrency seed phrases, aiming to drain victims' digital wallets. This activity forms part of a broader supply chain attack, impacting enterprise organizations and individuals outside the cryptocurrency industry, with crypto companies like Coinbase and Ledger and bulk email providers such as Mailchimp, SendGrid, Hubspot, Mailgun, and Zoho among the targeted companies.
PoisonSeed's method involves creating convincing phishing pages mimicking login portals for popular CRM and email platforms. These deceptive pages trick victims into revealing their credentials, after which the attackers automate the export of email lists and create API keys for persistent access. Compromised accounts are then used to send bulk phishing emails with urgent lures, such as fake wallet migration notices, urging recipients to set up new cryptocurrency wallets using a provided seed phrase. If entered, this seed phrase allows attackers to access the wallet and steal funds, initiating a cryptocurrency seed phrase poisoning attack. Silent Push analysts have identified an extensive list of Indicators of Compromise (IoCs) associated with PoisonSeed's infrastructure, including phishing domains like mailchimp-sso[.]com and C2 Servers with IP addresses such as 212.224.88[.]188. While PoisonSeed shares some tactics with known groups like Scattered Spider and CryptoChameleon, it's considered a distinct entity with a focus on cryptocurrency theft rather than ransomware attacks. This malicious campaign exploits CRM credentials to spread cryptocurrency seed phrase attacks, placing many wallets at risk of compromise. Recommended read:

The PoisonSeed phishing campaign represents a new and evolving cyber threat, targeting individuals with access to critical systems like Customer Relationship Management (CRM) platforms and bulk email services. This large-scale operation compromises corporate email marketing accounts to distribute emails containing crypto seed phrases, ultimately used to drain cryptocurrency wallets. Attackers focus on high-value targets, employing detailed reconnaissance to ensure their phishing emails reach the most impactful individuals. By mimicking legitimate services through carefully crafted emails and fake login pages, PoisonSeed exemplifies the evolving nature of phishing threats, deceiving victims into believing they are from legitimate sources.
PoisonSeed's attack methodology is distinguished by its sophisticated approach, targeting individuals with access to CRM systems and bulk email platforms. The first stage involves meticulous target identification, focusing on those with access to CRM systems and bulk email platforms, as these targets provide significant leverage for further attacks. The reconnaissance process includes analyzing the email services used by companies and identifying employees in relevant positions. Once targets are identified, the attackers craft professional phishing emails designed to deceive recipients, sending them from spoofed addresses to enhance their authenticity, often containing links to fake login pages hosted on carefully named domains. The phishing pages deployed by PoisonSeed are designed to capture sensitive information, particularly cryptocurrency wallet seed phrases. Victims are tricked into entering attacker-provided seed phrases while setting up new cryptocurrency wallets, allowing the attackers to monitor and eventually take control of these wallets once funds are deposited. Compromised accounts are then used to send bulk phishing emails, employing urgent lures, such as notifications about "restricted sending privileges" or fake wallet migration notices. Domains such as mail-chimpservices[.]com have been used to deceive MailChimp users, showcasing the campaign's attention to detail. Recommended read:

A newly uncovered ClickFix phishing campaign is tricking victims into executing malicious PowerShell commands, which subsequently deploy the Havok post-exploitation framework. This framework grants attackers remote access to compromised devices. The attackers cleverly conceal the different stages of their malware within SharePoint sites and employ a modified version of Havoc Demon in tandem with the Microsoft Graph API. This tactic is used to obfuscate command-and-control (C2) communications, making them appear as legitimate traffic within trusted Microsoft services.
The attack starts with a phishing email that has a HTML attachment, when opened, displays an error message, which uses the ClickFix technique to trick users into copying and executing a malicious PowerShell command into their terminal or PowerShell, thereby triggering the next-stage. The command downloads and executes a PowerShell script hosted on a server controlled by the attacker. This script checks for sandboxed environments, downloads the Python interpreter if needed, and executes a Python script serving as a shellcode loader for KaynLdr, launching the Havoc Demon agent on the infected host.

A sophisticated phishing campaign is underway, abusing the Webflow content delivery network (CDN) to steal credit card data and commit financial fraud. Attackers are hosting fake PDF documents on Webflow, embedded with CAPTCHA images and a real Cloudflare Turnstile CAPTCHA, to deceive users and evade detection by static scanners. This scheme targets individuals searching for documents on search engines, redirecting them to malicious PDFs.
These PDF files mimic a CAPTCHA challenge, prompting users to click and complete a genuine Cloudflare CAPTCHA, creating a false sense of security. Upon completion, victims are redirected to a page requesting personal and credit card details to "download" the supposed document. After entering their credit card details, users receive an error message, and repeated submissions lead to an HTTP 500 error page, while the attackers already have their information.
