What Is a Crypto Miner Virus?

A crypto miner virus, or cryptojacking malware, secretly uses a device’s CPU or GPU to mine cryptocurrency for an attacker, leading to increased electricity costs and potential hardware damage for the victim. It typically infects devices through phishing emails, pirated software, compromised websites, and malicious browser extensions. Monero is the preferred cryptocurrency for mining due to its efficiency on standard CPUs and privacy features. Signs of infection include overheating, high CPU usage, and increased electricity bills. Detection involves monitoring system performance and running antivirus scans. Prevention includes using antivirus software, keeping systems updated, and avoiding pirated software. Notable incidents include attacks on a European water utility and the Los Angeles Times website.

New Malware Exploits Windows Character Map to Evade Defender and Mine Crypto

Darktrace's autonomous detection system identified suspicious activity when a desktop initiated an unusual HTTP connection using a PowerShell user agent. The attack began with the download of a PowerShell script named “infect.ps1” from the IP address 45.141.87[.]195:8000, which dropped both legitimate and malicious binaries into the user’s AppData directory, including a signed version of AutoIt.exe and various encoded payloads. The attackers exploited Windows’ built-in Character Map (charmap.exe) to inject the miner code into its process space, evading antivirus detection. The loader performed checks for task manager presence, user privileges, and antivirus software, and bypassed User Account Control prompts. Once activated, the cryptominer operated discreetly, connecting to external mining pools like asia.ravenminer.com and monerooceans[.]stream. The malware was designed for persistence, re-downloading itself if terminated. Darktrace monitored the infected device, noting DNS requests and connections to Monero mining endpoints, which triggered high-fidelity alerts. Darktrace's Rapid Autonomous Response blocked the device’s outbound communications, preventing the malware from connecting to the mining pool and stopping over 130 attempted calls to external endpoints. The malware exhibited significant obfuscation, utilized legitimate binaries for side-loading, manipulated registry keys for persistence, and injected processes into trusted Windows applications. The incident underscores the threat posed by adaptive cryptojacking malware, which can drain productivity and inflate energy costs. Darktrace's AI-driven detection intercepted the attack early, mapping the kill chain and enabling rapid mitigation. Indicators of Compromise (IoCs) include: - 45.141.87[.]195:8000/infect.ps1 – Malicious PowerShell script - gulf.moneroocean[.]stream – Monero Endpoint - monerooceans[.]stream – Monero Endpoint - 152.53.121[.]6:10001 – Monero Endpoint - 152.53.121[.]6 – Monero Endpoint - https://api[.]chimera-hosting[.]zip/frfnhis/zdpaGgLMav/nbminer[.]exe – NBMiner executable - Db3534826b4f4dfd9f4a0de78e225ebb – NBMiner loader hash

New Android Malware Poses as SBI Card and Axis Bank Apps to Steal Financial Data

McAfee’s Mobile Research Team has identified a malware campaign targeting Android users in India, specifically Hindi speakers. The malware disguises itself as legitimate financial applications from banks like SBI Card, Axis Bank, and IndusInd Bank. It is distributed through phishing websites that mimic official banking portals and uses authentic assets to appear credible. The malware has dual functionality: it exfiltrates personal and financial data and mines Monero cryptocurrency using the XMRig tool, activated remotely via Firebase Cloud Messaging (FCM). It masquerades as a Google Play update, prompting users to install it, which leads to data theft. Upon installation, the malware presents a fake Google Play interface and requests sensitive information, which is sent to a command-and-control server. After data submission, users see a misleading confirmation page. The malware employs a multi-stage dropper to evade detection, with remote activation capabilities that keep it dormant until triggered. Phishing sites promote the malicious APK through SMS, WhatsApp, or social media. McAfee has reported these threats to Google, resulting in the blocking of the associated FCM account. All variants are classified as high-risk, with infections primarily in India but some in other regions. Users are advised to download apps only from Google Play and to be cautious with unsolicited links. Indicators of Compromise (IOCs) include specific APKs for various credit cards and phishing site URLs related to the campaign.
