Vulnerabilities that went undetected for a decade left thousands of macOS and iOS apps susceptible to supply-chain attacks. According to ArsTechnica, hackers could have added malicious code compromising the security of millions or billions of people who installed them.
The vulnerabilities, which were fixed last October, resided in a “trunk” server used to manage CocoaPods, a repository for open source Swift and Objective-C projects that roughly 3 million macOS and iOS apps depend on. When developers make changes to one of their “pods”—CocoaPods lingo for individual code packages—dependent apps typically incorporate them automatically through app updates, typically with no interaction required by end users.
“Many applications can access a user’s most sensitive information: credit card details, medical records, private materials, and more,” wrote researchers from EVA Information Security, the firm that discovered the vulnerability. “Injecting code into these applications could enable attackers to access this information for almost any malicious purpose imaginable—ransomware, fraud, blackmail, corporate espionage… In the process, it could expose companies to major legal liabilities and reputational risk.”
The firm added that, “While there is no direct evidence of any of these vulnerabilities being exploited in the wild, evidence of absence is not absence of evidence. Potential code changes could affect millions of Apple devices around the world across iPhone, Mac, AppleTV, and AppleWatch devices.”
