Researcher Found iPhone Activation Lock Bypass via Device Migration, Apple Has Since Patched It

·1 views

In June 2026, a security researcher discovered that an iPhone 13 running iOS 18.6, locked under an attacker's Apple ID after a phishing scheme, could be fully unlocked without any credentials. The method involved performing a factory reset and then using Apple's Device-to-Device Migration (Quick Start) feature with a nearby iPhone 7 running iOS 15.8.8, which silently replaced the attacker's Activation Lock with the source device's Apple ID. A second factory reset after the migration left the iPhone 13 completely free of any Activation Lock. The researcher followed a 30-day responsible disclosure process with Apple, which acknowledged the issue and confirmed the behavior is no longer present in current software builds. The findings raise broader concerns about the reliability of Activation Lock as a theft-deterrence mechanism on older iOS versions.

How developers can cap costs when AI agents query large data warehouses autonomously

Autonomous AI agents can answer complex business questions by querying databases and iterating through trial-and-error, but this loop can become extremely expensive on large platforms like BigQuery. Unlike human analysts who scope queries carefully, agents may run unoptimized scans across entire columns, with a single 100TB query potentially costing over $600 at standard pricing. A developer using Google's Antigravity SDK and the Data Agent Kit built a cost-safe agent with two guardrails: one that dry-runs every query before execution to block oversized scans, and another that pauses the agent for human approval once token spending crosses a set budget. The post highlights that common assumptions — such as LIMIT clauses reducing scan costs — are false in columnar databases like BigQuery, where charges are based on bytes read rather than rows returned. The guardrails aim to make autonomous data agents practical in production environments without exposing organizations to runaway infrastructure costs.

Multi-Tenancy Explained: How One App Serves Many Businesses Securely

Multi-tenant architecture allows a single software system to serve multiple independent customers, called tenants, from a shared infrastructure while keeping their data strictly isolated. The most common approach uses shared database tables where every row is tagged with a tenant_id column to identify which tenant owns each piece of data. Engineers must layer multiple isolation mechanisms — including middleware, API gateways, and encryption — to ensure no tenant can access another's data. Supporting principles such as load balancing, idempotency, and dependency injection work together to keep the system reliable and maintainable at scale. Compared to single-tenant systems, multi-tenancy reduces infrastructure costs and maintenance overhead, though it demands significantly more engineering discipline to implement correctly.
