Swiss cheesed off as postal service used to spread malware

November 16, 2024 at 02:16AM

Switzerland’s NCSC warned citizens about malware spread through fake letters from the Federal Office of Meteorology, promoting a dangerous “Severe Weather Warning App.” The app, a malicious imitation of Alertswiss, contains the Coper trojan, targeting banking credentials. This method of delivery via postal service is unprecedented, indicating targeted spear-phishing efforts.

**Meeting Takeaways: Switzerland’s National Cyber Security Centre (NCSC) Malware Alert**

1. **New Malware Distribution Method**: The NCSC has issued an alert about a novel method of malware distribution using physical letters sent via the postal service in Switzerland.

2. **Fraudulent Letters**: The letters are designed to appear genuine, mimicking correspondence from the Federal Office of Meteorology and Climatology. Recipients are prompted to scan a QR code and download a fraudulent weather app named “AlertSwiss,” which is a fake version of the legitimate Alertswiss app.

3. **Malicious App Details**: The fake app is hosted on a third-party website, not found on the official Google Play Store. It contains the Coper trojan, which is capable of keylogging, intercepting SMS two-factor authentication messages, and targeting banking applications to steal sensitive data.

4. **Threat Severity**: The NCSC recognizes this as a serious threat, noting the letters appear official and trustworthy, which may pressure individuals into taking hasty actions.

5. **Limited Reporting**: The exact number of impacted individuals is unknown due to the lack of a universal reporting requirement in Switzerland, although the NCSC has received reports from over a dozen people.

6. **Targeted Approach**: The cost of sending these letters (approximately $1.35 each) suggests the tactic is being used for spear-phishing targeted at specific individuals rather than mass distribution.

7. **Historical Context**: Using QR codes maliciously is not a new phenomenon; however, employing postal letters for this purpose marks a first for cybersecurity alerts.

8. **Potential High Rewards**: Despite the seemingly inefficient method, the potential payoff from targeting high-value individuals, given Switzerland’s wealth, may justify the scammers’ investment.

9. **Ongoing Monitoring**: The NCSC and other cybersecurity entities should continue to monitor this situation and educate the public on identifying potential fraudulent communications.

10. **Recommendation for Caution**: Citizens are advised to verify the authenticity of any communication asking for sensitive information or directing them to download applications via QR codes.
