How to Detect Spyware on iPhone: Signs & What to Do

Key takeaways:

  • Regularly look at your app permissions and data usage to spot unfamiliar and hidden apps early.
  • Most unauthorized access is actually password theft, so make sure you protect your Apple ID to stop remote monitoring and help detect spyware attempts.
  • If you can't detect spyware but still see suspicious behavior, a factory reset is the safest way to clear spyware on iPhone, provided you do not restore from a backup created after the spyware was installed.

    • We keep a lot of private information in our pockets, so it’s normal that many people worry about spyware on their iPhone. The good news is that device-level spyware is rare on iPhones due to Apple’s high security. It’s hard for hackers to install malicious software unless they have your device in their hands or you are a high-value target.

    What Is Bridge Mode? Router & Modem Explained Simply

    Key takeaways:

  • Bridge mode helps to turn off the routing functions of a modem or a router to avoid NAT issues.
  • Setup differs based on your device's model and firmware, but generally can be done by rebooting the device into bridge mode.
  • Bridge mode is most useful for bypassing ISP routers, fixing double-NAT issues, and advanced network setups.

    • Increasing performance or implementing basic security features, such as a router VPN, on your home or office network requires advanced settings. ISP-provided routers or a one-device setup might lack the needed capabilities, so a workaround is to connect multiple routers or modems.

    Double NAT: What It Is and How to Fix It

    Key takeaways:

  • If your router's WAN IP is private (like 192.168.x.x), you likely have a double-NAT issue. While it doesn't affect basic browsing, it’ll need fixing if you plan to game online or access your home network remotely.
  • If the issue is caused by your hardware, the most reliable fix is to enable bridge mode on the modem provided by your ISP.
  • For the best performance, only one device in your home should be performing Network Address Translation at any given time.

    What is a Residential Proxy? How It Works & Use Cases

    Key takeaways:

  • Residential proxies work by rerouting your online traffic through a residential IP address assigned to physical devices owned in different households.
  • Residential proxies provide a big pool of IP addresses, a high level of legitimacy and privacy, along with a deep anonymization of your identity.
  • There can be rotating or dedicated residential proxies and they are best used for web scraping, SEO monitoring, account management, and ad verification.

    • A residential proxy is a type of intermediary server that uses household IP addresses to mask your identity online. Unlike other similar servers that use cloud-hosted IPs, this proxy employs IP addresses that are assigned to physical devices in different residential areas by Internet Service Providers (ISPs).

    When you send a request online while using this proxy, your request comes from one of the residential IP addresses assigned to a particular device owned by an actual person.

    It seems like the request was sent from that device because your traffic is routed through a residential proxy as a middleman that uses this IP address.

    Traffic becomes significantly less susceptible to tracking or figuring out your identity, which makes your web activities not linked to your physical location or other private data.
