![]() ![]() SwiftUI is a revolutionary framework to create user interfaces with a declarative Swift syntax.Swift is an intuitive programming language that is safe, fast, and modern.Innovative tools help you create great apps Xcode includes the Xcode IDE, Swift and C/C++/Objective-C compilers, Instruments analysis tool, simulators, the latest SDKs, and hundreds of powerful features: The Xcode IDE combined with the Swift programming language make developing apps easy and fun. Xcode provides developers a unified workflow for user interface design, coding, testing, and debugging. Users can also consider multilayered security solutions such as Trend Micro Antivirus for Mac, which provides comprehensive security and multidevice protection against cyberthreats.Įnterprises can take advantage of Trend Micro’s Smart Protection Suites with XGen™ security, which infuses high-fidelity machine learning into a blend of threat protection techniques to eliminate security gaps across any user activity or endpoint.Xcode includes everything developers need to create great applications for Mac, iPhone, iPad, Apple TV, and Apple Watch. To protect systems from this type of threat, users should only download apps from official and legitimate marketplaces. Affected developers will unwittingly distribute the malicious trojan to their users in the form of the compromised Xcode projects, and methods to verify the distributed file (such as checking hashes) would not help as the developers would be unaware that they are distributing malicious files.įurther details of this attack may be found in its related technical brief. The method of distribution used can only be described as clever. Capturing screenshots of certain accessed sites.Blocking the user from changing passwords but also stealing newly modified passwords.Stealing credit card information from the Apple Store.Stealing amoCRM, Apple ID, Google, Paypal, SIPMarket, and Yandex credentials.Modifying /replacing Bitcoin/cryptocurrency addresses.The UXSS attack is theoretically capable of modifying almost every part of the user’s browser experience as arbitrary JavaScript-injected code. It encrypts files and shows a ransom note, if commanded by the server.It uploads files from the affected machines to the attacker’s specified server.It takes screenshots of the user’s current screen.It steals information from the user’s Evernote, Notes, Skype, Telegram, QQ ,and WeChat apps.Uses the Safari development version to inject JavaScript backdoors onto websites via a Universal Cross-site Scripting (UXSS) attack.Uses a vulnerability to read and dump Safari cookies.Using exploits, it abuses the existing the Safari and other installed browsers to steal user data.Once present on an affected system, XCSSET is capable of the following behavior: Infected users are also vulnerable to having their credentials, accounts, and other vital data stolen. This eventually leads to the main XCSSET malware being dropped and run on the affected system. These Xcode projects have been modified such that upon building, these projects would run a malicious code. Presumably, these systems would be primarily used by developers. It is not yet clear how the threat initially enters these systems. ![]() ![]() This threat primarily spreads via Xcode projects and maliciously modified applications created from the malware. We detected the entry threat as and its command and control (C&C) related files as. This blog will summarize the findings of this threat, while its accompanying technical brief contains the full details of this attack. We have also identified this threat in sources such as VirusTotal, which indicates this threat is at large. The threat escalates since we have identified affected developers who shared their projects on GitHub, leading to a supply-chain-like attack for users who rely on these repositories as dependencies in their own projects. This poses a risk for Xcode developers in particular. This scenario is quite unusual in this case, malicious code is injected into local Xcode projects so that when the project is built, the malicious code is run. Most notable in our investigation is the discovery of two zero-day exploits: one is used to steal cookies via a flaw in the behavior of Data Vaults, another is used to abuse the development version of Safari. Upon further investigation, we discovered that a developer’s Xcode project at large contained the source malware, which leads to a rabbit hole of malicious payloads. We have discovered an unusual infection related to Xcode developer projects. ![]()
