If you read the tech headlines on a daily basis, you'll be forgiven for thinking we're in the middle of a security crisis that is rife with software viruses and malware, and that's certainly true. These threats affect all of our Internet-connected devices, from smart speakers to laptops and cell phones.
Although Android may feel that Android is insecure, you do not hear much about iOS. Many people believe that Apple's iPhones are immune to viruses or malware, others worry, but what is the truth? Can iPhones get viruses?
"Theoretically yes," said Maik Morgenstern, AV-Test's Chief Technology Officer, Digital Trends. "However, the practical hurdles are quite high and it is unlikely that a normal user will be affected. However, there are vulnerabilities that can be exploited by attackers.
People tend to use the word virus to describe all unwanted and uncharged software. Technically, however, the term refers to software that infects a host, inserts itself into an existing program, and then spreads that infection by self-replication. Malware (malicious software) is only a small percentage ̵
How safe is iOS
Apple has been criticized for its walled garden because it does not offer as many choices and customizations as some alternatives, but there are some advantages to being more restrictive.
"Because iOS is a closed ecosystem, users can only install apps from the App Store that are carefully reviewed by Apple," said Morgenstern. "Malware writers are unlikely to receive malware in the store."
Of course, this does not mean that this is impossible, and there have been incidents where legitimate apps in the iOS App Store have been infected with malware. In one case, cybercriminals were able to trick Chinese app developers into using a fake version of an Apple development tool.
"Another infection vector can be the vulnerability in iOS that attackers can infect your device," Morgenstern said.
"Malware writers are unlikely to receive malware in the store."
Already in 2017, WikiLeaks published details about the hacking tools of the CIA. The report included some methods that the CIA had used to exploit vulnerabilities in iOS iPhones. Apple was quick to release a statement stating that most vulnerabilities had already been fixed and the rest would be done soon. However, it is absolutely plausible that someone outside knows a vulnerability in the system and is currently exploiting it to find more. Just as the people at Apple work tirelessly to block them and fix vulnerabilities.
One of the reasons why iOS is relatively safe compared to Android is that cybercriminals and other attackers first take the path of least resistance or low-hanging fruit. Many of the vulnerabilities discovered in Android are patched only slowly on each device. Google can act fast, but updates are only available on some phones when manufacturers and operators bring this together. Apple does not have this problem, so patches can be pushed out much faster. There are also many more Android users, so it's a bigger target.
Common Threats on Different Platforms
Successful phishing attacks that force people to reveal sensitive details are common to iOS and Android because they are not essential. People need to install something first. A victim can appear with a seemingly legitimate login screen, but was actually created by criminals, and when he enters his credentials, he hands it over effectively.
We've also experienced a surge in hitting, that's really just phishing over mobile text messages. Users may receive a seemingly normal text message from a large company with a link. If you tap on this link, they will be redirected to a fake website or trigger a malware download. This type of message covers all sorts of tax refunds, including security alerts that you need to update your bank details.
Being hunted out of details should be easy to avoid. Never log in via links in emails, text messages, or social media messages. Enter the address in your browser or log in using the app.
Malware is a bit of a vampire – it needs to be downloaded to your iPhone. By default, you can not install apps outside the App Store. If you get an unexpected pop-up that tries to install something over and over again, do not load it. However, there is still the risk of making annoying things like web page redirects that plague you with popups. If you encounter them, go to Settings> Safari> Clear History and Website Data and then tap again to confirm that you should be good.
How do you know if your iPhone has a virus?
The simple answer to this is that you often have no idea if your device has malware installed. False alarms are far more common than actual problems. People will often interpret a badly coded app, a lost environment or an aging battery as a sign of malware.
"Do not jailbreak the device and install updates as they become available."
If You Find This If you notice any suspicious behavior on your iPhone, you will certainly want to investigate. However, if you do not have a jailbroken device, it is likely that it is not caused by viruses or malware. Try securing your iPhone and reset the device to factory settings to see if your issues are resolved. If the strange behavior persists, visit an Apple Store and ask them to look for you.
What can you do to reduce the risk?
There are some good iPhone security apps and VPN apps A good idea, but these options are more than anything else focused on your privacy. If you stick to the Apple App Store, you usually do not have to worry about having a virus or malware on your iPhone.
"If no people block their device, they can not install unchecked third-party vendors. Party apps, "said Morgenstern.
So if you're worried about staying safe, the answer is simple:
"Do not jailbreak the device and always install updates as they become available to fix existing security vulnerabilities. "
