WeWorm – First 0-Click Worm Spreading Through WeChat Calls Across iOS and Android

Researchers demonstrated WeWorm, a zero-click worm exploiting a memory-corruption flaw in WeChat's VoIP stack to spread via calls across iOS and Android.

Security firm Calif published WeWorm, a proof-of-concept zero-click worm exploiting a memory-corruption bug in WeChat's VoIP stack to spread through voice calls on iOS and Android without the victim answering. The demo chained a Pixel 10a, an iPhone 17e, and a second Pixel 10a, compromising each device while the call was still ringing and giving full control of the WeChat account. The attacker must already be on the victim's friend list, but compromised contacts become the propagation layer across a platform with over 1.4 billion monthly users. Calif reported the bug to Tencent in July 2026, and Tencent has since mitigated it; full technical details are withheld for a later conference presentation.

California's Digital Age Assurance Act forces Windows, macOS, iOS, and Android to collect age brackets from January 2027, with open-source exemptions pending.

California's Digital Age Assurance Act, signed in October 2025, requires major operating systems to collect user age brackets (under 13, 13-15, 16-17, 18+) and share non-identifying age signals with app developers starting January 1, 2027, with existing setups complying by July 1, 2027. AB1856, passed in late August 2026, would exempt open-source operating systems under GPL, MIT, BSD, and Apache licenses and awaits the governor's signature. Colorado, Illinois, and New York have similar age assurance measures, and the EFF has criticized the law for privacy and censorship concerns.

Pegasus Zero-Click Spyware Exploit Infects Serbian Student Movement Member's iPhone

Citizen Lab confirms Pegasus zero-click iMessage spyware infected a Serbian student activist's iPhone amid at least 14 spyware targets in Serbia during 2026.

The Citizen Lab, with the SHARE Foundation, confirmed an iMessage zero-click exploit infected a Serbian student protest movement member's iPhone with NSO Group's Pegasus spyware, with high-confidence indicators from December 2025 to January 2026. The exploit was addressed by Apple in iOS 18.4.1, released April 2025. At least 14 people in Serbia, including students, activists, an MP, and a councilor, were targeted with advanced spyware since the start of 2026, coinciding with March 29, 2026 local elections; a new Android spyware similar to NoviSpy was also found on a confiscated device.

Pegasus, NoviSpy variant spyware found on devices of Serbian activists

Researchers confirmed the first 2026 Pegasus infection and a new NoviSpy variant on 14 Serbian activists, likely surveillance by Serbian authorities ahead of elections.

Citizen Lab confirmed with high probability the first forensically confirmed Pegasus infection of 2026, on a Serbian student activist hacked via a zero-click exploit between December of last year and January. Amnesty International confirmed two devices infected with a new NoviSpy variant, and the SHARE Foundation documented 14 targets including a member of parliament and a local government official, the largest documented spyware wave in Serbia to date. Evidence points to Serbian police or intelligence services, with NoviSpy infections occurring around police detention ahead of key local and parliamentary elections. Apple threat notifications preceded the findings, and updated iOS versions break the exploit chain.

13 Malicious Packagist Packages Target Unpatched iPhones to Steal Crypto Wallet Seeds

Trojanized Packagist themes inject JavaScript into Vietnamese streaming sites, exploiting unpatched iPhone WebKit and kernel flaws to install spyware and steal crypto wallet seeds.

Socket researchers found 13 malicious Composer theme packages across five vendor namespaces (including vsmov, vsphim, and ophimcms) that inject JavaScript into Vietnamese movie and comic streaming sites. On iPhones running iOS 18.4-18.6.x, the injected code fires a WebKit-to-kernel exploit chain using CVE-2025-31277 and CVE-2025-43529, pivoting through the GPU process and the AppleM2ScalerCSCDriver IOKit user client to gain kernel read/write. Since around August 12, 2026 the payload also steals cryptocurrency wallet seeds and mnemonics from Bitget, BitKeep, Bitpie, Phantom, Tonkeeper, Trust Wallet, and OKX, alongside keychain databases, Wi-Fi passwords, SMS, photos, cookies, and location history, uploaded via HTTPS to rotating C2 domains. The group is believed to be Vietnamese-operated, hosts exploits on Funnull infrastructure, and Apple patched the kernel escape flaw in iOS and macOS 26.1.

Apple iCloud Private Relay Can Expose Real IPs Through WebKit Proxy Bypasses

Researchers found WebKit features bypass proxies and iCloud Private Relay, leaking users' real IP addresses; Apple patched in iOS 26.6.1 and macOS 26.6.2.

Researchers Talal Haj Bakry and Tommy Mysk found that three WebKit features — DNS prefetching, WebAuthn Related Origin Requests, and WebTransport — bypass configured proxies and send traffic directly from the device. This leaks the user's real IP address in Safari and all WebKit-based iOS browsers and undermines iCloud Private Relay's dual-hop privacy design. Any website can trigger the leak via WebAuthn without user interaction or passkey use; a proof-of-concept site, leaks.psylo.app, demonstrates the issue. Apple investigated and patched the leaks in iOS 26.6.1 and macOS 26.6.2.

Apple warned hundreds of users of mercenary spyware attacks

Apple sent threat notifications to users in 110 countries warning of targeted mercenary spyware attacks and recommending Lockdown Mode.

Apple sent a new round of threat notifications warning users in 110 countries they may have been individually targeted by mercenary spyware, adding to alerts issued in more than 150 countries since the program began in 2021. The company says such attacks are vastly more sophisticated than criminal activity, cost millions of dollars, and typically target journalists, activists, politicians, diplomats, and lawyers. Apple recommends verifying notices directly at account.apple.com, enabling Lockdown Mode, keeping devices updated, and seeking expert help such as Access Now's Digital Security Helpline. Citizen Lab researchers note the alerts can reveal that entire communities are under targeted surveillance.

  • Buffer Overflow in Apple WebKit (Safari, iOS/iPadOS, macOS, WebKitGTK, WPE)
    CVE-2025-31277 is a memory-handling flaw (buffer overflow, CWE-119/CWE-120) in Apple's WebKit engine, the component that renders web content in Safari and in webviews across Apple platforms. It is triggered when a user processes maliciously crafted web content, typically by visiting an attacker-controlled page, causing memory corruption that can compromise the rendering process, with CVSS 3.1 scoring high impact to confidentiality, integrity and availability (8.8) via a network vector requiring user interaction but no privileges. Everyone running WebKit is affected: Safari users and devices on iOS/iPadOS, macOS Sequoia, tvOS, visionOS and watchOS prior to the fixed releases, plus Linux users of WebKitGTK and WPE WebKit as shipped with Red Hat Enterprise Linux (including the AUS and ELS channels). Exploitation is confirmed in the wild: CISA added the bug to its Known Exploited Vulnerabilities catalog on 2026-03-20 (ransomware linkage unknown) with a BOD 22-01 remediation deadline of 2026-04-03, and contemporaneous reporting describes 'DarkSword', an iOS exploit kit chaining multiple Apple flaws, reportedly including zero-days, in global attacks, possibly including this bug. No public proof-of-concept is known, and fixes shipped in Safari 18.6, iOS/iPadOS 18.6, macOS Sequoia 15.6, tvOS 18.6, visionOS 2.6 and watchOS 11.6.

  • Improper Locking Memory Corruption in Apple iOS, iPadOS, macOS, tvOS, visionOS, watchOS
    CVE-2025-43510 is an improper locking flaw (CWE-667) in Apple's operating systems that leads to memory corruption, addressed by improved lock state checking. It is triggered locally: a malicious application already running on the device can cause unexpected changes in memory shared between processes, with the CVSS vector (AV:L, UI:R) indicating user interaction is required but no privileges needed beforehand. Successful exploitation could corrupt or expose cross-process shared memory, yielding high impacts on confidentiality, integrity, and availability (CVSS 3.1 score 7.8), and such shared-memory corruption bugs in Apple's OSes are commonly leveraged as steps in chained attacks such as sandbox escapes. All users of iOS, iPadOS, macOS (Sonoma, Sequoia, and Tahoe branches), tvOS, visionOS, and watchOS on versions earlier than the fixed releases are affected. The vulnerability is being exploited in the wild: CISA added it to the Known Exploited Vulnerabilities catalog on 2026-03-20 with a federal patching deadline of April 3, 2026, and news reports describe an active iOS exploit kit ('DarkSword') using multiple Apple flaws, including zero-days, in global attacks.
