Slow Fog: iPhone Safari attack that led to the theft of encrypted assets has not yet been confirmed

According to Cointelegraph, blockchain security company SlowMist stated that its investigation has not linked the recent security warning caused by the iPhone Safari attack to confirmed cryptocurrency theft incidents.

SlowMist told Cointelegraph that it has not independently confirmed any victims affected by the specific Safari attack samples it analyzed, and the strongest technical evidence it possesses covers iOS versions 18.4 to 18.6.2. The company stated that the reported impact range of "iOS 13 to 26.5" should be regarded as a preliminary assessment, and it tends to avoid claiming that iOS 26.5 is affected until reproducible technical evidence is obtained.

SlowMist pointed out that the Safari attack reused the previously disclosed DarkSword exploit chain technology, which is independent of another investigation involving malicious components embedded in App Store applications called FomoPeek. The Google Threat Intelligence Group (GTIG) disclosed DarkSword in March, describing it as an iOS exploit chain used by multiple threat actors since November 2025.
