近日，澳洲多家機場的免費WiFi和USB充電站被曝存在嚴重安全隱患，引發留學生與華人旅客的高度警惕。據悉，部分旅客在使用機場提供的公共WiFi或將手機通過USB線連接至充電站時，遭遇個人信息被盜、銀行賬戶資金被轉走的安全事件。這一消息在社交媒體上迅速傳播，引起華人社群與澳洲當地媒體的廣泛關注。

事件的核心問題在於，公共場所的USB充電口及免費WiFi網絡本身可能被植入惡意程序或存在監控設備。不法分子可通過所謂的“充電劫持”（juice jacking）技術，利用旅客在充電時與充電端口的數據連接，竊取手機內的敏感信息，包括聯絡人、短信、照片，甚至銀行和支付應用的登入憑證。同時，公共WiFi也可能被假冒或加密不良，當設備自動連接至這些網絡時，網絡流量極易被攔截，造成個人隱私和財產安全風險。

對此，美國運輸安全管理局（TSA）及多個安全專家均發出警告，提醒旅客切勿將手機或其他移動設備的數據線直接插入不明USB充電口，尤其是在機場、咖啡廳、酒店等公共場所。此外，使用公共WiFi時應避免訪問銀行、支付或涉及個人敏感信息的網站，並建議啟用手機自帶的數據保護與加密功能，如VPN或私人熱點。

此類事件對留學生、商務人士及頻繁出行的旅客尤其具有威脅性。許多受害者在事件曝光後表示，他們在不知情的情況下，僅僅通過公共充電線或WiFi上網，銀行賬戶便被異常交易，損失金額不等。此外，社群內也流傳多起類似案例，顯示這一問題並非個案，而是一種逐漸擴大的安全隱患。

專家指出，解決此類風險的核心在於提高旅客的安全意識，並採取實際防護措施。例如，攜帶外接充電寶（僅供供電，不帶數據傳輸功能）、使用自備充電線或轉換器，避免使用公共USB端口；在WiFi使用方面，盡量選擇官方提供的安全網絡，並配合VPN加密流量；對於重要賬戶應啟用雙重驗證及實時交易提醒，防止資金被盜。

總體而言，此次澳洲機場安全事件提醒所有出行旅客，便利往往伴隨隱患。免費WiFi與公共USB充電雖然方便，但背後存在極高的信息和財產風險。留學生、華人旅客及頻繁出行者需時刻提高警惕，採取必要的防護措施，以避免個人敏感信息被盜取，造成財產損失或更大安全隱患。

Recently, several airports in Australia have come under scrutiny after reports revealed serious security risks associated with their free WiFi networks and USB charging stations, raising alarms among international students and Chinese travelers. Some passengers who used the airport’s public WiFi or connected their smartphones to USB charging ports reportedly had personal information stolen and funds transferred from their bank accounts, causing widespread concern within the Chinese community and local media coverage.

The core issue lies in the fact that public USB charging ports and free WiFi networks may be compromised or contain malicious programs. Criminals can exploit so-called “juice jacking” techniques, in which a device connected to a compromised USB port has its data siphoned, including contacts, messages, photos, and even login credentials for banking and payment apps. Similarly, public WiFi networks—especially unsecured or spoofed networks—can intercept internet traffic, putting sensitive information and financial assets at risk.

In response, the U.S. Transportation Security Administration (TSA) and cybersecurity experts have issued warnings advising travelers not to plug their phones or other mobile devices into unknown USB charging ports, particularly in airports, cafes, hotels, and other public spaces. When using public WiFi, passengers are advised to avoid logging into bank accounts or other websites containing sensitive information and to use built-in encryption tools such as VPNs or personal hotspots.

These risks are particularly relevant to international students, business travelers, and frequent flyers. Victims reported that their bank accounts experienced unauthorized transactions after simply connecting to a public USB port or WiFi, with financial losses varying by case. Social media and community forums have also shared numerous similar incidents, indicating that this is not isolated but rather a growing security concern.

Experts recommend practical steps to mitigate these threats. Travelers can carry power banks that only provide power without data transfer capabilities, use personal charging cables or adapters instead of public USB ports, and rely on secure, official WiFi networks with VPN encryption. Critical accounts should have two-factor authentication and real-time transaction alerts to prevent unauthorized access.

Overall, the incidents at Australian airports serve as a stark reminder that convenience often comes with hidden risks. Free WiFi and USB charging stations, while convenient, carry significant threats to personal data and financial security. Travelers, particularly international students and Chinese visitors, should remain vigilant and adopt precautionary measures to protect sensitive information and avoid potential financial loss.
