Recent developments in cybersecurity have shown a new type of attack called snail mail cyber-attacks. In this method, cybercriminals use regular postal services to send harmful content. People especially note this tactic in Switzerland.
Attackers send fake letters with QR codes. These codes lead to malware downloads on Android devices.
Cybercriminals are using physical letters that appear to come from legitimate organizations. Recently, some of these letters promoted a fake "severe weather warning app." They also had QR codes. When scanned, these codes install malware called Coper, also known as Octo2, on the victim's device.
Once the malware installs, it attempts to steal sensitive information from various applications, including banking apps. The malware is capable of advanced features such as device takeover and credential theft through overlay attacks.
This method leverages people's trust in physical mail and familiarity with QR codes. Many individuals do not associate physical mail with cyber threats, making them more susceptible to such attacks. Experts note that this tactic effectively bypasses digital security measures that protect against email-based phishing scams.
To protect against such threats, we recommend the following:
- Avoid Scanning Unsolicited QR Codes: Treat QR codes with the same caution as email links. If a QR code appears suspicious or unsolicited, do not scan it.
- Download Apps Only from Official Stores: Always download apps from trusted app stores to reduce the risk of harmful software.
- Verify Communication Sources: Always confirm the legitimacy of any communication claiming to be from trusted organizations before taking action.
- Learn About Phishing: Keep up with new phishing tricks and help others stay alert to possible cyber threats.
The rise of snail mail cyber-attacks shows how cybersecurity is changing. Experts update traditional methods to fight new threats. As cybercriminals continue to innovate, maintaining awareness and employing best practices for digital security is essential for safeguarding personal information.
