In the opening paragraphs, we’ll provide quick answers to key questions about whether iPhones can get malware. Yes, iPhones can get malware, but it is less common than on Android devices. iPhones have strong security protections built into iOS that make it difficult for malware to infect them. However, no device is completely immune to malware. iPhones can be infected through vulnerabilities in iOS, malicious apps, or if the device has been jailbroken. Staying vigilant and keeping your iPhone up to date are the best ways to avoid malware.
What is malware?
Malware is short for “malicious software.” It refers to any program or code that is harmful to devices or users. Malware comes in many forms, including viruses, worms, trojans, ransomware, spyware, adware, and more. The main goals of malware are to steal sensitive information, gain unauthorized access, corrupt data, display unwanted ads, or hold devices hostage for ransom payments.
Can iPhones get infected with malware?
Yes, iPhones are susceptible to malware attacks just like any computing device, but the risk is lower than on Android. There are several reasons why malware is less common on iPhones:
- iOS is a closed operating system that Apple tightly controls, making it more difficult for malware to get into their App Store.
- App developers must follow Apple’s strict guidelines and code review process before apps get approved.
- Apps in the App Store are sandboxed, which separates them from critical system resources.
- Apple quickly issues security updates and patches for known iOS vulnerabilities.
- iPhone users cannot install apps from third-party sources outside the App Store by default.
However, while iPhones have strong defenses, they are not completely invulnerable to malware. There are still a few infection vectors that attackers can exploit:
iOS vulnerabilities
Like any software, iOS is not perfect. New vulnerabilities in the operating system are discovered occasionally. Hackers can try to exploit these security flaws to sneak malware onto devices. For example, the Pegasus spyware from NSO Group exploited iOS vulnerabilities to infect iPhones.
Malicious apps
While Apple thoroughly reviews apps, sometimes malware slips through. For example, some apps gathered user data secretly violating Apple’s policies. Developers can also update their apps with malicious code after approval. Apps like Jekyll did this, initially looking harmless so they get approved, then later updating to add malicious functionality.
Third-party app stores
If an iPhone is jailbroken, users can install apps from outside the App Store which poses greater risks. There is no code review on third-party stores, so the likelihood of downloading malware is higher. Also, sideloading enterprise apps intended for employee devices could potentially introduce malware if the IPA file is compromised.
What are the most common iPhone malware threats?
Here are some of the most prevalent types of malware seen on iPhones:
Spyware
Spyware secretly monitors activity on devices and sends data to attackers. Some spyware like Pegasus can activate microphones and cameras. Spyware often exploits iOS vulnerabilities to install itself. Signs of spyware include abnormal battery drain, sluggish performance, and overheating.
Adware
Adware bombards users with intrusive ads. It can come bundled with apps or trick users into clicking links to infect devices. The revenue from forced ad clicks is how adware generates money for attackers. Excessive pop-up ads are the most obvious sign of adware.
Ransomware
Ransomware encrypts data on iPhones until a ransom is paid. It often pretends to be legitimate apps like AntiVirus software. Users suddenly cannot access their data without the decryption key held by attackers. Jailbroken iPhones are more susceptible to ransomware attacks.
Scareware
Scareware deceives users into believing their device has a virus. It convinces victims to pay money to remove the non-existent threat. Fake security alerts warning your iPhone is infected are indicators of scareware. Rebooting your device makes the scareware infection go away.
Trojans
Trojans disguise themselves as useful apps then compromise iPhone security. They can gather personal data, install other malware, or gain backdoor access. Any app asking for unnecessary sensitive permissions like contacts could be a Trojan.
Botnets
Botnets take control of iPhones to use them in coordinated attacks controlled remotely by hackers. The network of compromised devices can be leveraged to send spam, engage in fraud, or conduct DDoS attacks. Strange traffic and crashing apps indicate an iPhone botnet infection.
Keyloggers
Keyloggers record your keystrokes to steal passwords, credit card numbers, and other sensitive data. They can track typing in browsers, apps, and even for phone calls. Any signs your iPhone is capturing typing input suggests a keylogger.
Rootkits
Rootkits are stealthy malware giving attackers root access to iPhones. They hide themselves deep in iOS to avoid detection. With total control, they can do anything from changing system files to making calls. Strange system crashes or altered settings indicate possible rootkit infection.
What can malware do to your iPhone?
If malware infects your iPhone, here are some of the potential impacts:
- Steal sensitive personal data like contacts, messages, photos
- Spy through cameras and microphones
- Gain access to financial or health apps and accounts
- Change software configurations
- Encrypt data and hold it ransom
- Redirect web traffic for click fraud or phishing
- Abuse device resources to mine cryptocurrency
- Gain remote control for inclusion in botnet attacks
- Brick or disable the device
- Leak compromising or embarrassing information
In general, the malware seeks to exploit your iPhone for profit, spying, or malicious purposes. Attackers can leverage infected devices in many creative ways to generate money or cause harm. The impacts could range from annoying to catastrophic depending on the type and severity of the malware infection.
How can I tell if my iPhone has malware?
Here are some signs that may indicate your iPhone is infected with malware:
