SpyNote: Android malware evolves

CYFIRMA analyzed SpyNote, an Android malware that poses a significant threat by allowing extensive control over infected devices. The malware hides itself as a fake antivirus named Avast Mobile Security for Android to deceive users. The malware targets cryptocurrencies, steals data from other apps, and collects user credentials. It monitors network traffic to connect to a C2 server for data theft. There are over 10,000 identified samples of SpyNote, with recent infections linked to the threat actor EVLF distributing it through platforms like Telegram. 

TA455 and its Dream Job campaign

The Iranian Dream Job campaign conducted by TA455 targeted the aerospace industry by offering fake jobs and distributing the SnailResin malware. The campaign has been active since at least September 2023 and uses fake recruiting websites and LinkedIn profiles to distribute malicious files. The attackers use a detailed PDF guide to encourage victims to download a ZIP file containing the malware. The campaign is suspected to be involved in espionage targeting aerospace, aviation, and defense industries in Middle Eastern countries.

The two vulnerabilities, tracked as CVE-2024-8068 and CVE-2024-8069, affect the Session Recording Manager component and stem from issues in how the data is deserialized. Citrix has refuted claims of an unauthenticated RCE exploit, stating that it is an authenticated RCE that can be carried out only as a NetworkService Account. 

Top Scams Reported in the Last 24 Hours

GoIssue facilitating GitHub phishing attacks

Researchers have discovered a tool, GoIssue, that can steal developer credentials in bulk and conduct malicious activities, including supply chain attacks. GoIssue gathers email addresses from public GitHub profiles by using automated processes and GitHub tokens, allowing attackers to send bulk emails directly to user inboxes. The tool is being marketed to potential attackers for $700 for a custom build or $3,000 for full source code access. It combines bulk email capabilities with data collection features and hides the attacker's identity through proxy networks.

With advanced techniques and creative exploits, cybercriminals are escalating their attacks on users' digital and financial lives. A revamped version of NodeStealer is targeting Facebook Ads Manager accounts to extract sensitive information and steal credit card data from web browsers. The malware employs sophisticated methods to access credit card details, which are then exfiltrated via Telegram. The WorkflowKit Race Vulnerability in macOS has exposed users to potential data breaches and remote code execution. The flaw arises from a race condition during the shortcut extraction process, allowing malicious apps to intercept and modify shortcuts during import. Apple addressed this critical issue in macOS 14.5 with enhanced sandbox restrictions. Adding to these growing concerns, criminals have devised a new scam known as Ghost Tap, exploiting NFC technology in mobile payment services. Using phishing tactics and mobile banking malware, attackers capture victims’ card credentials, link them to mobile wallets, and deploy mules to make fraudulent purchases at physical stores.
