U neofficijalnom Telegram klijentu Nekogram otkriven je obfuscated kod koji tajno \u0161alje brojeve telefona korisnika koji su se prijavili na aplikaciju botu «@nekonotificationbot», povezuju\u0107i ih s korisni\u010dkim identifikatorom. Promjena za prikupljanje brojeva telefona prisutna je samo u gotovim APK paketima koji se distribuiraju putem Google Playa, GitHuba i Telegram kanala projekta. U izvornoj kodu na GitHubu i u APK paketu iz F-Droid kataloga nedostaje ta promjena za prikupljanje telefona. <\/p>\n

Backdoor je bio prisutan u datoteci Extra.java. Pretpostavlja se da je slanje zapo\u010delo s verzijom Nekogram 11.2.3, u po\u010detku samo za korisnike s kineskim brojevima, a zatim za sve. U programu su tako\u0111er kori\u0161teni osint botovi «@tgdb_search_bot» i «@usinfobot» za identifikaciju korisnika prema njihovom ID-u, ali broj telefona im nije slan. \"Nekogram, <\/p>\n

Istra\u017eiva\u010di su pripremili Java hook i bot koji omogu\u0107uju svakom korisniku da se uvjeri u slanje brojeva telefona iz njegove instance aplikacije. \"Nekogram, <\/p>\n

Prema mi\u0161ljenju istra\u017eiva\u010da koji su otkrili problem, autori aplikacije su mogli koristiti prikupljenu informaciju za formiranje baze podataka za kasniju prodaju stvarateljima OSINT botova. O namjernom skrivanju ovakve aktivnosti svjedo\u010di obfuskacija izmjene i primjena inline upita za slanje podataka. Nakon otkrivanja problema u sustavu za pra\u0107enje gre\u0161aka projekta, autor Nekograma priznao je slanje brojeva telefona svom botu, ne obja\u0161njavaju\u0107i razloge takve aktivnosti, ali spominju\u0107i da poslane telefone nisu \u010duvali i nisu ih proslijedili nikome. <\/p>\n

Dodatno, mo\u017ee se primijetiti otkrivanje ranjivosti u slu\u017ebenoj Telegram aplikaciji. Projekat Zero Day Initiative (ZDI), koji nudi nov\u010dane nagrade za izvje\u0161taje o neopravdanim ranjivostima, objavio je preliminarne podatke o ranjivosti ZDI-CAN-30207 u Telegramu, koje je dobilo kriti\u010dnu razinu opasnosti (9.8 od 10) i ozna\u010deno je kao udaljeni napad, ne zahtijevaju\u0107i radnje od korisnika. Detalji \u0107e biti otkriveni 24. srpnja, daju\u0107i vrijeme programerima Telegrama da dostave ispravak korisnicima. <\/p>\n

Pojavila se nova informacija da se ranjivost manifestira prilikom otvaranja specijalno oblikovanih animiranih naljepnica u Telegramu i mo\u017ee dovesti do izvr\u0161enja koda napada\u010da bez ikakvih radnji korisnika. \u010cini se da je ranjivost uzrokovana gre\u0161kom u kodu biblioteke rlottie, koja omogu\u0107ava rad pregleda. <\/p>\n

Predstavnici Telegrama izjavili su da ne smatraju otkrivenu problematikom opasnom ranjivo\u0161\u0107u, budu\u0107i da se sve u\u010ditane naljepnice prethodno provjeravaju na poslu\u017eiteljima<\/a> Telegramu i sli\u010dna provjera ne bi dopustila prikazivanje zlonamjerne naljepnice korisnicima. Nakon izjava Telegrama, razina opasnosti ranjivosti smanjena je s 9.8 na 7.0.
