आज फिर हो सकता है रैनसमवेयर का साइबर अटैक, बचना होगा नामुमकिन, बरतें ये सावधानियाँ

WannaCrypt (copy)

 

साइबर सुरक्षा से जुड़ी संस्थाओं ने चेतावनी दी है कि शुक्रवार को हुए वैश्विक हमले के बाद दूसरा बड़ा साइबर हमला सोमवार को हो सकता है। शुक्रवार को हुए वैश्विक हमले से दुनिया भर के 125,000 से ज्यादा कंप्यूटर सिस्टम संक्रमित हो गए थे।

सोमवार को हर एक कंप्यूटर सिस्टम से 300 ड़ॉलर मूल्य के बिटकॉइन मांगे गए हैं। इन्हें नहीं चुकाने पर यह रकम 600 ड़ॉलर करने की चेतावनी है।

यदि रकम नहीं चुकाई गई तो वे सारी फाइलें नष्ट कर देंगें।

क्या है रैनसमवेयरः

रैनसमवेयर एक कंप्यूटर वायरस है जो कंप्यूटर्स फ़ाइल को बर्बाद करने की धमकी देता है। इसमें धमकी दी जाती है कि अगर अपनी फ़ाइलों को बचाना है तो फीस चुकानी होगी।

ये वायरस कंप्यूटर में मौजूद फ़ाइलों और वीडियो को इनक्रिप्ट कर देता है और उन्हें फिरौती देने के बाद ही डिक्रिप्ट किया जा सकता है।

इसमें फिरौती चुकाने के लिए समयसीमा निर्धारित की जाती है और अगर समय पर पैसा नहीं चुकाया जाता है तो फिरौती की रकम बढ़ जाती है।

रविवार को माइक्रोसॉफ्ट ने एक बयान जारी कर कंप्यूटर सिस्टम में सुरक्षा से जुड़ी जानकारी रखने के सरकारों के तरीके की आलोचना की।

माइक्रोसॉफ्ट ने कहा कि, “हमने देखा है कि किस तरह सीआईए की अतिसंवेदनशील सूचनाओं को विकीलीक्स ने चुराया और अब एनएसए से ऐसी ही संवेदनशील सूचनाएं चोरी होने से दुनियाभर में कंप्यूटर्स प्रभावित हुए हैं।”

8 अप्रैल 2014 के बाद से माइक्रोसॉफ्ट, विंडोज़ एक्सपी और विस्टा ऑपरेटिंग सिस्टम के लिए सुरक्षा पैच बनाना बंद कर चुकी है कंपनी ने इस ऑपरेटिंग सिस्टम का इस्तेमाल करने वालों से बेहतर ऑपरेटिंग सिस्टम पर काम करने की अपील भी की थी।

कैसे बचें रैनसमवेयर सेः

8 अप्रैल 2014 के बाद से माइक्रोसॉफ्ट, विंडोज़ एक्सपी और विस्टा ऑपरेटिंग सिस्टम के लिए सुरक्षा पैच बनाना बंद कर चुकी है। लेकिन फिरौती वायरस के हमले के बाद कंपनी ने विंडोज़ एक्सपी और विस्टा के लिए एक इमरजेंसी पैच जारी किया है।

  1. अनजान ईमेल पर आने वाले संदिग्ध लिंक्स पर क्लिक न करें।
  2. सुरक्षा विशेषज्ञों का कहना है कि किसी भी तरह के मेल के साथ आने वाले रार, जिप या इस तरह के कंप्रेश फाइल को खोलने से पहले सुनिश्चित कर लें कि यह सही हैं। अनजाने मेल या लॉटरी से संबंधित मेल को किसी भी तरह खोलने की कोशिश न करें।
  3. अपनी सारी ज़रूरी फाइलों का बैकअप एक ‘एक्सटर्नल ड्राइव’ में रखें।
  4. अपने कंप्यूटर के सिक्योरिटी सिस्टम को अपडेट रखें।
  5. फायरवॉल और एंटी वायरस सॉफ्टवेयर का इस्तेमाल करें।

My blog has a lot of unique content I’ve either authored myself or outsourced but it seems a lot of it is popping it up all over the internet without my permission. Do you know any techniques to help prevent content from being stolen? I’d genuinely appreciate it.
