Abasebenzisi abaningi be-inthanethi bathola ama-imeyili amaningi ogaxekile nsuku zonke ngokuvamile afinyelela kufolda yogaxekile. Ngenxa yezihlungi zogaxekile zanamuhla, abasebenzisi bangakwazi ukuqeda ama-imeyili amaningi ogaxekile. Omunye angase azibuze ngomthombo kanye nesisusa salokhu ku-imeyili yama-spam.

Kusuka lapha, bangathumela umyalo bese belawula amasignali e-C & C kusuka kuseva. Ikhompuyutha ethintekile yi-malware ayisekho ngaphansi komyalo womnikazi. Umhlaseli manje angenza umyalo ofana nokuhlaselwa kwe-DDoS kuwebhusayithi ethize. I-bot yenza i-unit functional ye-botnet. Ukusuka ekukhokheni lolu hlelo lokusebenza, umhlaseli usebenzisa isikhwama esimnyama ukumaketha kwe-digital kusho ukuyifaka efakwe kwikhompyutha yesisulu. Ezinye zezinyathelo ezisetshenziswayo zibandakanya ukuhlambalaza futhi ushintshe izikhangiso. Ngokwesibonelo, izinhlelo zokusebenza ze-Facebook ezivela emithonjeni enonya ngokuvamile ziqukethe amafayela anesifo. amanye amacala, laba bantu bathumela ama-imeyli ogaxekile. Amanye alawa ma-imeyili afaka amaTrojans, amafayili anegciwane noma izinamathiselo.

  • Nontanga ukubuka. I-bot ingaxhumana ngqo nomunye u-bot. Lokhu kwakha indlela enezingqimba yokuthumela imiyalo nokuthola impendulo. Kule ndlela, i-bot-master ingakwazi ukulawula ibhodlela lonke.
  • Hybrid: Leli qhinga lihlanganisa inqubo emibili echazwe ngenhla.

Uma usungula i-botnet ephumelelayo, umhlaseli angenza i-cyber-ubugebengu njengokuntshontsha idatha yakho. Ulwazi lomuntu siqu olufana nama-imeyli namaphasiwedi angadlulela ngalezi zindlela. Ngokujwayelekile, ukwebiwa kwekhadi lesikweletu, kanye nokulahlekelwa kwamaphasiwedi, kwenzeka ngokuhlaselwa kwe-botnet. Abasebenzisi abagcina idatha ebucayi njengeziqinisekiso zokungena ngemvume, ulwazi lwezezimali kanye nobungozi be-inthanethi yokukhokha inhlawulo ukuze bahlaselwe laba baduni.
