Threats tagged 'phishing'

A hacking group named NetMedved has been conducting phishing attacks against Russian organizations since October 2025. The campaign uses malicious LNK files disguised as business documents to deliver NetSupport RAT malware. The attackers employ various techniques including PowerShell scripts, finger protocol, and anti-analysis checks. They utilize multiple domains for payload delivery and command and control. The group's infrastructure overlaps with previous campaigns from 2024, suggesting an evolution of tactics rather than a new actor. NetMedved's operations involve social engineering, custom obfuscation, and abuse of legitimate tools to evade detection and maintain persistence on compromised systems.

A phishing campaign targeting Brazilian users spreads a banking trojan via WhatsApp Web by leveraging an open-source automation script. The attack starts with a malicious VBS script in a phishing email that downloads and executes an MSI installer and another VBS script. The second VBS installs Python and Selenium to inject malicious JavaScript into WhatsApp Web, enabling the malware to propagate by sending itself to the victim's contacts. The MSI drops an AutoIt script that monitors for Brazilian banking and cryptocurrency application windows and loads an encrypted payload into memory to evade detection. This payload specifically targets Brazilian financial institutions and cryptocurrency wallets. The campaign uses in-memory execution and automation to maintain stealth and persistence. No known exploits in the wild have been reported yet, and the campaign is currently assessed as medium severity. The attack is highly tailored to Brazilian users and financial targets but could pose risks if similar tactics spread elsewhere.

Following Hurricane Melissa's devastation in Jamaica in October 2025, cybercriminals launched a series of online scams exploiting the disaster. These scams included phishing campaigns, fake charity websites, and fraudulent financial-relief portals impersonating legitimate aid organizations. Attackers used social engineering tactics to prey on victims' compassion and urgency, often deploying scams within hours of the hurricane. A prominent example involved a cryptocurrency donation site with fabricated transaction data and static images to appear authentic. Numerous fraudulent domains soliciting cryptocurrency donations were identified. While primarily targeting individuals, these scams undermine trust in digital charity platforms and complicate legitimate relief efforts. European organizations involved in disaster relief, financial services, or public awareness campaigns should be vigilant. The threat is medium severity due to social engineering reliance and no direct system exploitation. Mitigation requires enhanced awareness, domain monitoring, and collaboration between cybersecurity entities and relief organizations.

The UNK_SmudgedSerpent threat actor, likely linked to Iranian espionage efforts, targeted academics and foreign policy experts from June to August 2025 using phishing campaigns with domestic political and health-related lures. The actor employed Remote Management & Monitoring (RMM) tools and credential harvesting techniques, showing overlapping tactics with known Iranian groups such as TA455, TA453, and TA450. Although attribution is not definitive, the targeting aligns with Iranian intelligence priorities, focusing on sensitive policy and academic sectors. The campaign's medium severity reflects moderate impact potential without known exploits in the wild. European organizations involved in foreign policy, academia, and research are at risk, especially in countries with strong diplomatic ties or geopolitical interest in Iran. Mitigation requires targeted user awareness, strict monitoring of RMM tool usage, and enhanced email filtering tuned to political and health-themed lures. Countries like Germany, France, the UK, Italy, and the Netherlands are most likely affected due to their active academic communities and diplomatic engagement with Iran. The threat's medium severity is due to its espionage focus, moderate ease of exploitation via phishing, and the absence of widespread destructive payloads or zero-day exploits. Defenders should prioritize detection of credential harvesting and suspicious RMM activity while maintaining vigilance for evolving Iranian espionage tactics.

Cybercriminals are targeting trucking and logistics companies to steal cargo freight through elaborate attack chains. They compromise companies and use their access to bid on cargo shipments, which they then steal and sell. The threat actors typically deliver remote monitoring and management (RMM) tools as a first-stage payload. This cyber-enabled theft is part of a multi-million-dollar criminal enterprise that has increased due to digital transformation. The attackers use tactics such as compromising load boards, email thread hijacking, and direct targeting via email campaigns. They deliver RMM tools like ScreenConnect, SimpleHelp, and PDQ Connect, which grant full control of compromised machines. The activity has been observed since at least June 2025, with nearly two dozen campaigns in the last two months alone.

Between August and October 2025, a phishing campaign targeted Colombian users by impersonating the Attorney General's office to deliver the PureHVNC Remote Access Trojan (RAT) via the Hijackloader malware loader. The attack chain involved sophisticated techniques such as DLL side-loading, anti-virtual machine checks, and multiple code injection methods to evade detection and maintain persistence. This campaign marks the first known use of Hijackloader to deliver PureHVNC in Spanish-speaking Latin America, signaling an evolution in regional threat actor tactics. Although primarily focused on Colombia, the use of phishing and advanced evasion techniques poses a risk to organizations with similar user profiles or language contexts. The campaign's medium severity reflects the complexity and potential for unauthorized remote access but lacks evidence of widespread exploitation beyond the initial targets. Defenders should prioritize user awareness, advanced endpoint detection, and monitoring for indicators of DLL side-loading and unusual process injections. No CVSS score is available; based on impact and exploitation complexity, the threat is assessed as medium severity.

In October 2025, a wave of sophisticated cyber attacks targeted corporate environments, leveraging phishing campaigns exploiting trusted platforms like Google Careers and ClickUp, abusing Figma for credential theft, and deploying the LockBit 5.0 ransomware variant against ESXi and Linux systems. Attackers used legitimate cloud services and multi-stage redirection to evade detection, while a new phishing kit named TyKit emerged. These campaigns threaten corporate credentials, infrastructure integrity, and data confidentiality across multiple sectors. The attacks do not require known exploits in the wild but rely heavily on social engineering and abuse of trusted platforms. Security operations centers (SOCs) must enhance detection capabilities, harden access controls, and employ advanced threat intelligence to mitigate these evolving threats. The overall severity is medium, reflecting the complexity and multi-vector nature of the attacks but without widespread exploitation of zero-day vulnerabilities. European organizations, especially those using affected platforms and cloud services, face significant risks from credential theft and ransomware infection.
