資訊安全貼士 (2022年4月號) – 如何防範電腦病毒及惡意軟件?

在日常生活中,我們會十分注意家居保安,但您會否擔心家中的電腦也可能會被不法分子入侵?他們會在您的電腦種下木馬程式來盜取重要資料,甚至遠端控制您的電腦鏡頭及音訊設備進行偷窺及竊聽。由於近年加密貨幣大行其道,也有黑客透過木馬程式大量地盜用他人的電腦資源來挖礦以獲取加密貨幣圖利。這種挖礦攻擊會令被入侵電腦的效能及網速下降、增加耗電及縮短電腦的壽命等。 挖礦攻擊其實已在世界各地不斷漫延,近日大學亦收到澳門網絡安全事故預警及應急中心通知,自本年2月以來,該中心發現多個澳門機構的電腦受到挖礦病毒感染,並呈上升趨勢。為確保資訊安全,希望大家參考以下提示,做好安全防護措施: 及時修補電腦操作系統及應用軟件的安全漏洞,安裝更新補丁或進行升級; 安裝並定期更新防毒軟件,為電腦進行定期掃描及開啟即時防護及監控功能; 只從供應商/發行商的官方網站下載軟件; 不要下載任何類型的破解或黑客程式; 不要開啟可疑電郵中的連結及附件; 加強賬號、密碼的安全管理和保護,例如使用雙重認證(2FA)服務和較複雜的密碼。 如電腦感染了病毒或惡意軟件,可能會出現的狀況包括: 效能變慢及不穩定,甚至無法使用; 出現過熱現象及耗電量增加; 硬碟中的資料被破壞或刪除,甚至整個硬碟被格式化; 瀏覽器的首頁被篡改、頻繁彈出廣告、被強行跳轉至其他網頁; 防毒軟件無故被關閉或停止運行。 若懷疑您的澳大帳號受到不法入侵或電腦感染了病毒或惡意軟件,請立即與 ICTO 服務中心聯絡。 參考資料 · 慎防被捲入網絡釣魚騙局當中 · 如何安全地下載及安裝應用軟件? · 你為防範勒索軟件做好了準備嗎? · 雙重認證服務 · 如何選擇一個強密碼? · 網上安全與保障的基礎知識 · 其他資訊安全貼士
