CIA Ba\u015fkan\u0131 John Ratcliffe, ABD Ba\u015fkan Yard\u0131mc\u0131s\u0131 J.D. Vance, Savunma Bakan\u0131 Pete Hegseth, Ulusal G\u00fcvenlik Dan\u0131\u015fman\u0131 Mike Waltz\u2019\u0131n da bulundu\u011fu Signal grubuna yanl\u0131\u015fl\u0131kla The Atlantic’in genel yay\u0131n y\u00f6netmeni Jeffrey Goldberg\u2019in de dahil edildi\u011fi ortaya \u00e7\u0131km\u0131\u015ft\u0131.<\/p>\n

SIGNAL BA\u015eKANI UYGULAMAYI SAVUNDU<\/strong><\/h3>\n

ABD’li siyaset\u00e7iler bu olayla ortaya \u00e7\u0131kan g\u00fcvenlik a\u00e7\u0131\u011f\u0131n\u0131 hararetle tart\u0131\u015f\u0131rken, Signal Ba\u015fkan\u0131 Meredith Whittaker, mesajla\u015fma uygulamas\u0131n\u0131n g\u00fcvenli\u011fini savundu.<\/p>\n

Whittaker, X’teki bir g\u00f6nderisinde uygulamay\u0131 “\u00f6zel ileti\u015fimde alt\u0131n standart” olarak tan\u0131mlad\u0131.<\/p>\n

“Biz a\u00e7\u0131k kaynakl\u0131, k\u00e2r amac\u0131 g\u00fctmeyen bir kurulu\u015fuz ve sistemimizde meta verileri ve mesaj i\u00e7eriklerini korumak i\u00e7in (u\u00e7tan uca \u015fifreleme) ve gizlili\u011fi koruyan teknolojiler geli\u015ftirip uyguluyoruz.”,<\/p>\n

SIGNAL NED\u0130R?<\/strong><\/h3>\n

Signal, Signal Messenger firmas\u0131 taraf\u0131ndan y\u00f6netilen, merkezi (tek elden y\u00f6netilen) sunucular \u00fczerinde \u00e7al\u0131\u015fan, a\u00e7\u0131k kaynakl\u0131 ve tamamen \u015fifrelenmi\u015f bir mesajla\u015fma hizmeti.<\/p>\n

A\u00e7\u0131k kaynak, bir uygulaman\u0131n veya hizmetin yaz\u0131l\u0131m\u0131n\u0131n herkesin eri\u015febilece\u011fi, g\u00f6r\u00fcnt\u00fcleyebilece\u011fi, de\u011fi\u015ftirebilece\u011fi ve da\u011f\u0131tabilece\u011fi \u015fekilde halka a\u00e7\u0131lmas\u0131, patentlenmemesi anlam\u0131na geliyor. A\u00e7\u0131k kaynak yaz\u0131l\u0131mlar, geli\u015ftiriciler taraf\u0131ndan s\u00fcrekli iyile\u015ftirilebilir ve \u00f6zg\u00fcrce kullan\u0131labilir. \u00d6rne\u011fin, Linux ve Firefox gibi projeler a\u00e7\u0131k kaynakl\u0131. Bu sayede g\u00fcvenlik uzmanlar\u0131 uygulaman\u0131n nas\u0131l \u00e7al\u0131\u015ft\u0131\u011f\u0131n\u0131 do\u011frulayabilir ve g\u00fcvenli kald\u0131\u011f\u0131ndan emin olabilir.<\/p>\n

HANG\u0130 B\u0130LG\u0130LER\u0130 TOPLAR?<\/strong><\/h3>\n

Signal uygulamas\u0131n\u0131n sunucular\u0131nda saklanan kullan\u0131c\u0131 verileri \u015funlar: Telefon numaralar\u0131, kullan\u0131c\u0131n\u0131n servise kat\u0131ld\u0131\u011f\u0131 tarih ve son oturum a\u00e7ma bilgileri.<\/p>\n

Kay\u0131t olmak ve bir hesap olu\u015fturmak i\u00e7in bir telefon numaras\u0131 gereklidir.<\/p>\n

Kullan\u0131c\u0131lar\u0131n ki\u015fileri, sohbetleri ve di\u011fer ileti\u015fimleri ise kullan\u0131c\u0131n\u0131n cihaz\u0131nda yani telefonunda saklan\u0131r ve belirli bir s\u00fcre sonra konu\u015fmalar\u0131n otomatik olarak silinmesi se\u00e7ene\u011fi sunulur.<\/p>\n

\u015eirket, web sitesinde belirtildi\u011fi \u00fczere hi\u00e7bir reklam alm\u0131yor veya hi\u00e7bir kurulu\u015fa ba\u011fl\u0131 de\u011fil. Bu y\u00fczden de di\u011fer bir\u00e7ok mesajla\u015fma uygulamas\u0131n\u0131n aksine Signal, kullan\u0131c\u0131 verilerini takip etmez veya depolamaz.<\/p>\n

Signal ayr\u0131ca kullan\u0131c\u0131lara telefon numaralar\u0131n\u0131 ba\u015fkalar\u0131ndan gizlemesine de olanak tan\u0131r.<\/p>\n

NASIL \u00c7ALI\u015eIR?<\/strong><\/h3>\n

Signal, u\u00e7tan uca \u015fifreleme kullan\u0131r.<\/p>\n

U\u00e7tan uca \u015fifreleme \u00f6zelli\u011fi, g\u00f6nderilen i\u00e7eriklerin yaln\u0131zca g\u00f6nderen ve teslim alan ki\u015fi taraf\u0131ndan okunabilmesini ve dinlenebilmesini, mesajlar\u0131n ba\u015fka hi\u00e7bir sunucuda tutulmamas\u0131n\u0131 sa\u011flar. B\u00f6ylece WhatsApp dahil olmak \u00fczere \u00fc\u00e7\u00fcnc\u00fc taraflar\u0131n, mesajlar\u0131n i\u00e7eri\u011fine eri\u015fmesi engellenir.<\/p>\n

Bu \u00f6zellik kabaca \u015f\u00f6yle i\u015fler: Mesajla\u015fan taraflar i\u00e7in birer \u00e7ift anahtar \u00fcretiliyor. G\u00f6nderilen mesajlar \u015fifreleniyor ve bu \u015fifre yaln\u0131zca al\u0131c\u0131n\u0131n elindeki anahtarla a\u00e7\u0131labilir.<\/p>\n

Yani X ve Y mesajla\u015f\u0131rken uca \u015fifrelemeli bir uygulama kullan\u0131rsa s\u00fcre\u00e7 \u015f\u00f6yle i\u015fler: Mesajlar\u0131 \u015fifreleyebilen ve \u015fifresini \u00e7\u00f6zebilen anahtarlar, iki kullan\u0131c\u0131n\u0131n da cihaz\u0131nda kay\u0131tl\u0131 kal\u0131r. Uygulama X’in telefonunda bir anahtar ve Y’nin telefonunda bir anahtar kaydeder. X’in telefonu mesaj\u0131 anahtarla \u015fifreler, ard\u0131ndan \u015fifrelenmi\u015f mesaj\u0131 Y’nin telefonuna iletir. Y’nin telefonu anahtar\u0131 otomatik olarak devreye sokar ve mesaj\u0131n \u015fifresini \u00e7\u00f6zer. B\u00f6ylece Y, mesaj\u0131n i\u00e7eri\u011fini g\u00f6rebilir.<\/p>\n

Bu, Signal’in kendisinin bile kullan\u0131c\u0131lar\u0131n \u00f6zel konu\u015fmalar\u0131 ve aramalar\u0131n\u0131n i\u00e7eri\u011fine eri\u015femeyece\u011fi ve bunlar\u0131 okuyamayaca\u011f\u0131 anlam\u0131na gelir; b\u00f6ylece kullan\u0131c\u0131lar\u0131n\u0131n gizlili\u011fi garanti alt\u0131na al\u0131nm\u0131\u015f olur.<\/p>\n

Bug\u00fcn WhatsAppd da kullan\u0131c\u0131 mesajlar\u0131n\u0131n i\u00e7eriklerini gizlemek i\u00e7in Signal’in \u015fifreleme sistemini kullan\u0131yor.<\/p>\n

NE KADAR G\u00dcVENL\u0130?<\/strong><\/h3>\n

Siber g\u00fcvenlik firmas\u0131 iVerify’\u0131n sahibi ve ak\u0131ll\u0131 telefon kullan\u0131c\u0131lar\u0131n\u0131 bilgisayar korsanlar\u0131ndan koruyan Rocky Cole, Reuters haber ajans\u0131na yapt\u0131\u011f\u0131 a\u00e7\u0131klamada, Signal’in “b\u00fcy\u00fck bir \u00fcne sahip oldu\u011funu, g\u00fcvenlik camias\u0131nda yayg\u0131n olarak kullan\u0131ld\u0131\u011f\u0131n\u0131” s\u00f6yledi.<\/p>\n

Cole, “Signal’de son derece hassas ulusal g\u00fcvenlik bilgilerinin tart\u0131\u015f\u0131lmas\u0131n\u0131n yaratt\u0131\u011f\u0131 risk, Signal’in kendisinin g\u00fcvenli olmamas\u0131ndan kaynaklanm\u0131yor” diye ekledi.<\/p>\n

Ancak Cole’\u00fcn aktar\u0131m\u0131na g\u00f6re Signal kullanmak, hassas verilerin korunmas\u0131 i\u00e7in tek ba\u015f\u0131na yeterli de\u011fil. Zira bilgisayar korsanlar\u0131 “cep telefonunun kendisini hackleyebilir, cihazlara uzaktan eri\u015febilir.<\/p>\n

“Telefonun kendisi g\u00fcvenli de\u011filse, o cihazdaki t\u00fcm Signal mesajlar\u0131 okunabilir.”<\/p>\n

\u015e\u0130RKET\u0130N ARKASINDA K\u0130M VAR?<\/strong><\/h3>\n

\u015eirketin web sitesine g\u00f6re Signal, giri\u015fimci Moxie Marlinspike ve Whittaker taraf\u0131ndan 2012 y\u0131l\u0131nda kuruldu.<\/p>\n

\u015eubat 2018’de Marlinspike, WhatsApp’\u0131n kurucu orta\u011f\u0131 Brian Acton ile birlikte, \u015fu anda uygulamay\u0131 denetleyen kar amac\u0131 g\u00fctmeyen Signal Foundation’\u0131 kurdu. Acton, m\u00fc\u015fteri verilerinin kullan\u0131m\u0131 ve hedefli reklamc\u0131l\u0131k konusunda ya\u015fanan anla\u015fmazl\u0131klar nedeniyle 2017’de WhatsApp’tan ayr\u0131ld\u0131.<\/p>\n

Signal’in internet sitesinde, \u015firketin hi\u00e7bir b\u00fcy\u00fck teknoloji \u015firketine ba\u011fl\u0131 olmad\u0131\u011f\u0131 ve hi\u00e7bir zaman herhangi bir \u015firket taraf\u0131ndan sat\u0131n al\u0131nmayaca\u011f\u0131 belirtiliyor.<\/p>\n

K\u0130MLER SIGNAL KULLANIYOR?<\/strong><\/h3>\n

Gizlilik savunucular\u0131 ve aktivistler taraf\u0131ndan yayg\u0131n olarak kullan\u0131lan Signal, eskiden daha \u00e7ok muhaliflerin kulland\u0131\u011f\u0131 egzotik bir mesajla\u015fma uygulamas\u0131 olarak g\u00f6r\u00fcl\u00fcyordu.<\/p>\n

G\u00fcn\u00fcm\u00fczde ise gazeteciler i\u00e7in bir f\u0131s\u0131lt\u0131 a\u011f\u0131na ve hatta devlet kurumlar\u0131 i\u00e7in bir mesajla\u015fma arac\u0131na d\u00f6n\u00fc\u015ft\u00fc.<\/p>\n

O tarihte WhatsApp, kullan\u0131c\u0131 verilerinin Facebook (\u015fu anki ad\u0131yla Meta) ile daha fazla payla\u015f\u0131lmas\u0131n\u0131 \u00f6ng\u00f6ren bir gizlilik politikas\u0131 g\u00fcncellemesi duyurmu\u015ftu.
Bu g\u00fcncelleme, i\u015fletmelerin WhatsApp \u00fczerinden kullan\u0131c\u0131larla ileti\u015fim kurmas\u0131na ve baz\u0131 verilerin Facebook’un di\u011fer uygulamalar\u0131yla payla\u015f\u0131lmas\u0131na izin veriyordu. Bu g\u00fcncelleme T\u00fcrkiye’de de b\u00fcy\u00fck tart\u0131\u015fmaya yol a\u00e7m\u0131\u015ft\u0131.<\/p>\n

Tepkiler \u00fczerine WhatsApp, g\u00fcncellemenin uygulanmas\u0131n\u0131 ertelemi\u015fti. Ancak erteleme ad\u0131m\u0131, Signal ve Telegram gibi alternatif mesajla\u015fma uygulamalar\u0131n\u0131n h\u0131zla pop\u00fclerle\u015fmesine engel olamam\u0131\u015ft\u0131.<\/p>\n

DEVLET AKT\u00d6RLER\u0130N\u0130N SIGNAL KULLANMASI DO\u011eRU MU?<\/strong><\/h3>\n

2017’de ABD Senatosu Silahl\u0131 Kuvvetleri personelinin Signal kullanmas\u0131n\u0131 onaylam\u0131\u015ft\u0131.<\/p>\n

\u00d6te yandan, CCS Insight ba\u015f analisti Ben Wood, Donald Trump’\u0131n \u00fcst d\u00fczey dan\u0131\u015fmanlar\u0131n\u0131n Yemenli Husi militanlar\u0131na y\u00f6nelik askeri sald\u0131r\u0131 planlar\u0131n\u0131 Signal’de tart\u0131\u015fmas\u0131n\u0131 onaylamad\u0131\u011f\u0131n\u0131 dile getirdi.<\/p>\n

Reuters’a konu\u015fan Wood, \u015f\u00f6yle ekledi:<\/p>\n

“Signal’in, u\u00e7tan uca \u015fifrelemesi ve \u00e7ok az kullan\u0131c\u0131 verisi toplamas\u0131 nedeniyle t\u00fcketicilere \u00e7ok g\u00fcvenli ileti\u015fimler sundu\u011fu yayg\u0131n olarak kabul edilse de, ulusal g\u00fcvenlikle ilgili mesajlar i\u00e7in uygun oldu\u011funa inanmak zor.”<\/p>\n<\/div>\n
