CoinGecko<\/strong>‘nun 2026 Kripto G\u00fcvenlik Raporu<\/strong>, Ocak 2025 ile Temmuz 2026 aras\u0131nda 245 sald\u0131r\u0131da toplam 3,63 milyar dolar kaybedildi\u011fini ortaya koydu. Daha \u00e7arp\u0131c\u0131 olan ise sald\u0131r\u0131ya u\u011frayan platformlar\u0131n yakla\u015f\u0131k %60’\u0131n\u0131n daha \u00f6nce ba\u011f\u0131ms\u0131z g\u00fcvenlik denetiminden ge\u00e7mi\u015f olmas\u0131.<\/p>\n

Kripto<\/strong> sekt\u00f6r\u00fcnde g\u00fcvenlik a\u00e7\u0131klar\u0131 b\u00fcy\u00fcmeye devam ediyor. CoinGecko’nun verilerine g\u00f6re Ocak 2025 ile Temmuz 2026 aras\u0131nda 245 belgelenmi\u015f olayda 3,63 milyar dolar kaybedildi.<\/p>\n

\u00dcstelik kay\u0131plar\u0131n b\u00fcy\u00fck b\u00f6l\u00fcm\u00fc birka\u00e7 b\u00fcy\u00fck sald\u0131r\u0131da topland\u0131. En b\u00fcy\u00fck 10 sald\u0131r\u0131, \u00e7al\u0131nan toplam de\u011ferin %72,5’inden fazlas\u0131n\u0131 olu\u015fturdu.<\/p>\n

Rakam\u0131n arkas\u0131ndaki nedenler ise platformdan platforma de\u011fi\u015fiyor. Merkezi borsalarda \u00f6zel anahtarlar\u0131n ele ge\u00e7irilmesi \u00f6ne \u00e7\u0131karken merkeziyetsiz uygulamalarda ak\u0131ll\u0131 s\u00f6zle\u015fme a\u00e7\u0131klar\u0131 daha b\u00fcy\u00fck bir sorun olu\u015fturuyor.<\/p>\n

Kripto Sald\u0131r\u0131lar\u0131n\u0131n En B\u00fcy\u00fck Nedeni Ne?<\/h2>\n

CoinGecko’nun raporunda en a\u011f\u0131r kay\u0131plar\u0131n ba\u015f\u0131nda altyap\u0131 ve tedarik zinciri a\u00e7\u0131klar\u0131 geliyor. Bu t\u00fcr sald\u0131r\u0131lar CEX ve DEX platformlar\u0131nda toplamda 1,8 milyar dolardan fazla kayba yol a\u00e7t\u0131.<\/p>\n

Merkezi borsalarda en yayg\u0131n sorun, \u00f6zel anahtarlar\u0131n ele ge\u00e7irilmesi. Merkeziyetsiz uygulamalarda ise sald\u0131rganlar\u0131n ak\u0131ll\u0131 s\u00f6zle\u015fmelerdeki a\u00e7\u0131klar\u0131 kullanmas\u0131 \u00f6ne \u00e7\u0131k\u0131yor. Bu kategorideki olaylar yakla\u015f\u0131k 546 milyon dolarl\u0131k kayba neden oldu.<\/p>\n

Bunun yan\u0131nda oracle sistemleri ve piyasa manip\u00fclasyonu da iki farkl\u0131 platform t\u00fcr\u00fc i\u00e7in ortak risk olu\u015fturuyor. Bitget, Binance ve Hyperliquid gibi b\u00fcy\u00fck oyuncular\u0131n ya\u015fad\u0131\u011f\u0131 kay\u0131plar, yaln\u0131zca ak\u0131ll\u0131 s\u00f6zle\u015fme hatlar\u0131n\u0131n de\u011fil, platformlar\u0131n kendi \u00e7al\u0131\u015fma mekanizmalar\u0131n\u0131n da sald\u0131r\u0131ya a\u00e7\u0131k oldu\u011funu g\u00f6steriyor.<\/p>\n

Sorun burada bitmiyor. Sald\u0131rganlar art\u0131k sadece do\u011frudan kod a\u00e7\u0131klar\u0131n\u0131 aram\u0131yor. Sahte kullan\u0131c\u0131 aray\u00fczleri ve k\u00f6t\u00fc niyetli entegrasyonlar da g\u00fcvenlik riskinin bir par\u00e7as\u0131 haline geliyor.<\/p>\n

\"\"<\/p>\n

Listenin ba\u015f\u0131nda 1,436 milyar dolarl\u0131k kay\u0131pla Bybit yer al\u0131yor. KelpDAO 292 milyon dolar, Drift Protocol<\/strong><\/a> 285 milyon dolar ve Cetus 223 milyon dolarl\u0131k kay\u0131pla onu takip ediyor.<\/p>\n

G\u00fcvenlik Denetimi Yap\u0131lan Projeler Neden Hackleniyor?<\/h2>\n

Raporun en dikkat \u00e7ekici bulgular\u0131ndan biri burada ortaya \u00e7\u0131k\u0131yor.<\/p>\n

2025’in ba\u015f\u0131ndan bu yana kaydedilen 245 olay\u0131n 147’sinde sald\u0131r\u0131ya u\u011frayan platform daha \u00f6nce ba\u011f\u0131ms\u0131z bir g\u00fcvenlik denetiminden ge\u00e7mi\u015fti. Bu platformlar, toplam \u00e7al\u0131nan sermayenin %88,44’\u00fcn\u00fc olu\u015fturdu.<\/p>\n

Yani bir protokol\u00fcn denetlenmi\u015f olmas\u0131, sald\u0131r\u0131ya kar\u015f\u0131 g\u00fcvende oldu\u011fu anlam\u0131na gelmiyor.<\/p>\n

CoinGecko’ya g\u00f6re bunun \u00f6nemli bir nedeni denetimlerin kapsam\u0131. Bir\u00e7ok sald\u0131r\u0131 do\u011frudan denetlenen ak\u0131ll\u0131 s\u00f6zle\u015fmenin i\u00e7indeki hatadan kaynaklanm\u0131yor. Bunun yerine d\u0131\u015f altyap\u0131, sonradan yap\u0131lan ve denetlenmemi\u015f kod g\u00fcncellemeleri veya y\u00f6neti\u015fim mekanizmalar\u0131 hedef al\u0131n\u0131yor.<\/p>\n

\u0130lgin\u00e7 bi\u00e7imde, olaylar\u0131n yaln\u0131zca %11’i denetim kapsam\u0131ndaki ak\u0131ll\u0131 s\u00f6zle\u015fme a\u00e7\u0131klar\u0131yla do\u011frudan ba\u011flant\u0131l\u0131yd\u0131. Buna ra\u011fmen bu sald\u0131r\u0131lar bile yakla\u015f\u0131k 396 milyon dolarl\u0131k kayba yol a\u00e7t\u0131.<\/p>\n

Bu tablo, denetim raporunun tek ba\u015f\u0131na yeterli bir g\u00fcvenlik katman\u0131 olmad\u0131\u011f\u0131n\u0131 g\u00f6steriyor. Merkezi borsalarda ise durum farkl\u0131. Bu platformlar genellikle merkeziyetsiz protokol denetimleri yerine uyum kontrolleri ve Proof-of-Reserves gibi finansal do\u011frulama mekanizmalar\u0131na dayan\u0131yor. Ancak bunlar da sosyal m\u00fchendislik sald\u0131r\u0131lar\u0131n\u0131 veya \u00f6zel anahtarlar\u0131n ele ge\u00e7irilmesini \u00f6nlemiyor.<\/p>\n

Kripto Sigortalar\u0131nda Neden Para Azal\u0131yor?<\/h2>\n

Sald\u0131r\u0131lar\u0131n b\u00fcy\u00fcmesine ra\u011fmen kripto sigortas\u0131 taraf\u0131nda ters y\u00f6nde bir hareket var.<\/p>\n

CoinGecko, en b\u00fcy\u00fck zincir \u00fcst\u00fc sigorta protokollerindeki aktif teminat\u0131n 163,2 milyon dolardan 130,2 milyon dolara geriledi\u011fini belirtiyor. D\u00fc\u015f\u00fc\u015f %20,2 seviyesinde.<\/p>\n

\u00dcstelik toplam \u00f6demeler yakla\u015f\u0131k 33 milyon dolarda kal\u0131rken sigorta kapsam\u0131n\u0131n darald\u0131\u011f\u0131 g\u00f6r\u00fcl\u00fcyor.<\/p>\n

Bunun \u00f6nemli bir nedeni, y\u00fcksek risk ortam\u0131n\u0131n kullan\u0131c\u0131lar\u0131n hem teminat sa\u011flamas\u0131n\u0131 hem de y\u00fcksek primleri \u00f6demesini zorla\u015ft\u0131rmas\u0131. Ayr\u0131ca sigorta \u00fcr\u00fcnlerinin kapsam\u0131 \u00e7o\u011fu zaman olduk\u00e7a s\u0131n\u0131rl\u0131.<\/p>\n

\u00d6rne\u011fin baz\u0131 poli\u00e7eler yaln\u0131zca do\u011frulanm\u0131\u015f ak\u0131ll\u0131 s\u00f6zle\u015fme sald\u0131r\u0131lar\u0131n\u0131 veya belirli altyap\u0131 sorunlar\u0131n\u0131 kar\u015f\u0131l\u0131yor. \u0130nsan hatas\u0131, ele ge\u00e7irilmi\u015f \u00f6zel anahtarlar veya genel piyasa hareketlerinden kaynaklanan kay\u0131plar kapsam d\u0131\u015f\u0131nda kalabiliyor.<\/p>\n

Bu nedenle kripto sekt\u00f6r\u00fcnde sald\u0131r\u0131lar artarken sigortan\u0131n ayn\u0131 h\u0131zda b\u00fcy\u00fcmemesi yeni bir g\u00fcvenlik a\u00e7\u0131\u011f\u0131 yarat\u0131yor.<\/p>\n

Borsalar Kullan\u0131c\u0131lar\u0131n\u0131 Nas\u0131l Korumaya \u00c7al\u0131\u015f\u0131yor?<\/h2>\n

Merkezi borsalar bu tabloya kar\u015f\u0131 farkl\u0131 bir y\u00f6ntem kullanmaya ba\u015flad\u0131: koruma fonlar\u0131.<\/p>\n

CoinGecko’nun raporunda, baz\u0131 merkezi borsalar\u0131n bir sald\u0131r\u0131 veya g\u00fcvenlik a\u00e7\u0131\u011f\u0131 durumunda kullan\u0131c\u0131 zararlar\u0131n\u0131 kar\u015f\u0131lamak i\u00e7in \u00f6zel rezervler olu\u015fturdu\u011fu belirtiliyor.<\/p>\n

Bu yakla\u015f\u0131m, kullan\u0131c\u0131lar\u0131n yaln\u0131zca teknik g\u00fcvenli\u011fe de\u011fil, sald\u0131r\u0131 sonras\u0131nda nas\u0131l korunacaklar\u0131na da bakmaya ba\u015flad\u0131\u011f\u0131n\u0131 g\u00f6steriyor.<\/p>\n

Ancak sekt\u00f6r\u00fcn \u00f6n\u00fcndeki sorun daha geni\u015f. Ocak 2025 ile Temmuz 2026 aras\u0131nda kaydedilen 245 olay\u0131n ard\u0131ndan, zincir \u00fcst\u00fc sigorta ekosistemindeki 9 protokol\u00fcn 5’i faaliyetini durdurdu veya ba\u015fka alanlara y\u00f6neldi.<\/p>\n

Ortaya \u00e7\u0131kan tablo olduk\u00e7a net: Kriptoda sald\u0131r\u0131lar\u0131n maliyeti b\u00fcy\u00fcrken, g\u00fcvenlik denetimleri tek ba\u015f\u0131na yeterli olmuyor ve sigorta kapasitesi ayn\u0131 h\u0131zda geni\u015flemiyor. CoinGecko’nun verileri, g\u00fcvenli\u011fin art\u0131k yaln\u0131zca kodu denetlemekten ibaret olmad\u0131\u011f\u0131n\u0131; altyap\u0131, anahtar y\u00f6netimi, entegrasyonlar ve sald\u0131r\u0131 sonras\u0131 kullan\u0131c\u0131 korumas\u0131n\u0131n birlikte ele al\u0131nmas\u0131 gerekti\u011fini ortaya koyuyor.<\/p>\n
