How to hack a person's phone number? Hacking a number or hacking a phone with a phone number are phrases that we usually hear a lot and we have seen some people who are looking for a way to hack other people's mobile numbers. But probably many of them or even you are not familiar with the exact meaning of hacking and hacking the phone and you have heard or repeated only one phrase over and over again. In this post, we are going to see how to hack a number or hack a phone with a number.

We have written before about spying and its types, as well as the world's intelligence services that infiltrated people's privacy, but this time we do not want to talk about the operating system or a specific website, today we want to talk about about the security of telecommunications infrastructure services. And let's talk about a connection that we use every day. Imagine that people can see all your activities and listen to all your phone calls, and they can only do this by having your phone number. Just having your phone number and no need to install the smallest software on your mobile phone and the interesting thing is that you can not do anything because you are not responsible for establishing this communication system and this is scary.

Spy app with just a phone number


Is it possible? Just having our phone number hacked?

It's really scary, imagine that all your movements are monitored and spied on by cybercriminals. The question is, is this possible? The answer of a German information security expert who has done research in this regard is positive. An information security expert at the Berlin Security Research Laboratory in Germany says that it is very simple that a hacker can access all your conversations and information just by having your phone number.

To prove this, one of the employees of this research center was even tested with a simple Apple phone, and in the end, 60 minutes of this employee's conversations were accurately recorded and spied on.

But one of the security experts, Carsten Nohl, a German who is a member of the hacking team of this security research center, says that cybercriminals in this hack do not hack users' devices, but because of the security weakness in communication systems and infrastructure. There are telecommunications used and the user can not contribute to the security of this mechanism at all.

This very dangerous security vulnerability is known as Signaling System Seven or SS7 , which can virtually hack and spy on almost any phone. This test, as we said, was performed quite practically on the volunteer's mobile phone, and after using SS7, the phone was officially hacked with only one phone number. After performing this hack, information such as phone calls, all contacts, text messages, and even GPS information and the location of the person in question was visible to the hacker. However, the flow did not end with these cases, and it was even possible to make contact with contacts, etc. in this hack.

As we said before, this vulnerability is not on your mobile phone and exists in telecommunication and telephone infrastructure. Installing or preventing the installation of any software on the phone can not cause any problems in the work process of this vulnerability. It's the Mobile Network that is being hacked, not your cell phone. You will be horrified and angry to hear this, because your cell phone may have been spied on without your knowledge. Nohl went on to say that almost all cell phones could be hacked this way.

No matter what brand you use, a hacker can use this method to hack your bank accounts, email accounts, etc. because most security mechanisms include Two Factor Authentication or dual-purpose mobile authentication to do so. use. The SS7 vulnerability is almost new and was reported in August 2015. It is interesting to know that this vulnerability exists in the telecommunication infrastructure that is used in more than 800 communication companies in the world.

How does SS7 Defect or Vulnerability work?

The mechanism of this security flaw is not very complicated, the hacker redirects all the phone calls made to the target phone to a device or online voice recording system and then redirects the desired call to the mobile phone user or Re-Route and thus performing a Man In The Middle or MITM attack. If hacked in this way, the hacker can detect the slightest movement of the user and use all other hacking tools to spy on all user activities.

It is interesting to note that Nohl has stated that this security vulnerability has existed in information systems and that the world's intelligence and security services have been aware of this vulnerability and have even used it.

How to hack a phone number?

So far you have noticed that it is possible to hack a phone through a phone number, but the question that arises is how to do this and what are the methods to hack a phone number? There are many ways to do this, but most of them require learning programming languages. Learning programming languages ​​is not an easy task at all and it takes a lot of time, which is why many people give up. Of course, professional programmers around the world have designed software for hacking phones and made them available to the public, which can be used to easily hack other people's phones.

Plc spy program is also one of the programs designed and offered by the child control system to monitor children in cyberspace. This program is offered in several versions with different capabilities that hack the phone both with and without access and through your phone number. Using PLC SPY program, you can take control of your child's phone and have full control over his activities. This program allows you to view the location moment by moment, view incoming and outgoing SMS, contact list, contacts, and all images in the gallery. Also, in the new version of this program, which has been released under the name of PLC PLUS, the ability to listen to conversations and

Viewing the surrounding images by the child's phone camera has been added. You can install this version if you have access to your child's phone, or you can send the program link to your child with the name of a useful program and ask him to click on the link, as soon as the child clicks, the program will be installed automatically And then removed from the list of phone applications so that the child does not notice that the program is a trojan.

What is an attack on the SS7 spy app ?

An SS7 attack is a security breach that takes advantage of a flaw in the way SS7 (Signaling System 7) was built so that data can be stolen, conversations can listen in on, texts can be stolen, and a person's location can be tracked.

SS7 attacks are different from other types of cyberattacks because they can use many vulnerabilities to do bad things, most of which can be done from anywhere in the world. With these methods, attackers may be able to record and listen in on conversations and read text messages without being caught. Different kinds of SS7 attacks can also be used to track someone's location, commit fraud, or stop service.

How does an attack using SS7 work?

The SS7 protocol makes it easier for 2G and 3G wireless networks to talk to each other. It allows for the exchange of information needed to make and receive calls and text messages on a mobile phone, keeps track of billing information, and lets smartphone users roam while they are traveling. At first, SS7 networks were made to be a closed, trusted system between phone companies. Providers also worked with government agencies to allow for state surveillance by giving a lot of user information to anyone who had access to the SS7 system. When mobile devices and apps became more popular, another set of communication protocols was added on top. This created a lot of entry points and weak spots that hackers could use to get to private data and change it.

In 2014, security researchers in Germany showed that SS7 had flaws by showing that man-in-the-middle attacks could be used to track the movements and communications of cell phone users and listen in on their conversations. In 2017, hackers took money from their victim's bank accounts and put it in their own. They did this by getting access to SS7 and rerouting the two-factor authentication codes that were supposed to verify the account holders.

The effects of SS7's security flaws

Because the SS7 network has built-in surveillance tools, hackers can get a lot of useful information from SS7 attacks. This makes it easy for network operators, governments, cybercriminals, and hobbyists to track and hack smartphones , but businesses can reduce their risk by using best practices like virtual private network s, encryption, and security awareness training.

Even though the problems with SS7 were known, phone companies were slow to put protections in place, and some never did. By adding new security protocols, 4G and 5G telecommunications networks have made the threat less of a problem, but they still need to work with older technology. In its 2021 mobile report, the GSMA, an organization for telecommunications, said that 2G and 3G network access are used by 30% of mobile phone connections. 5G is becoming more popular, but SS7 attacks will still be a problem as long as 2G and 3G networks are still in use.

How to hack a phone: Seven common ways to do it

Most of the time, mobile security is better than PC security, but users can still be tricked and phones can still be hacked. Here's what you should keep an eye out for.

The rise of smartphones was supposed to give the tech industry a second chance to roll out a secure computing platform. The idea was that these new devices would be harder to hack than PCs and servers, which often have bugs.

But it turns out that phones are still computers and that the people who use them are still people, and computers and people will always be weak links. We talked to several security experts to find out what the most common ways are for hackers to get into the powerful computers that your users carry around with them. This should give you a better idea of where you might be vulnerable.

How to Hack a Phone: 7 Ways

Malvertising Social engineering

Smishing\Malware

Pretexting

By using Bluetooth to break in

Wi-Fi attacks by a "man in the middle"

Trying to change society

Hackers can get into any device easily if the person who uses it opens the door. This is the goal of most social engineering attacks, even though it's easier to say than to do.

Most smartphone operating systems are more secure than PCs or servers. Application code runs in a sandboxed mode, which keeps it from getting more privileges and taking over the device. But that much-praised security model, in which mobile users must take action for code to access protected parts of the phone's operating system or storage, has a downside: it causes a lot of pop-up messages that many of us learn to ignore. Catalino Vega III, a Security Analyst at Kuma LLC, says, "Apps on mobile devices separate permissions so that rogue apps can't do whatever they want with your data." This is to protect the user from rogue apps that can do whatever they want with their data. "The question "Do you want to give this app access to your photos?" starts to sound familiar."

"This only adds one step between giving them access to the app and letting them use it," he says. "Most users will just give the app access to whatever it wants because they have been trained to accept most prompts as a way to get to the functionality they want. I think we may have all done this at some point."

Malvertising

"Malvertisements," which use the infrastructure built for the mobile advertising ecosystem, either in a browser or in an app, are one of the most common ways that these fake dialogue boxes get to people.

Chuck Everette, who is the Director of Cybersecurity Advocacy at Deep Instinct, says, "The goal is to get you to click on the ad." "They are trying to get you to click on something without giving you time to think about it. It might look like an alert or warning." He says that the goal is to "try to scare you or entice you to click on the link."

He gives the example of a game called Durak that tricked Android users into unlocking their phones by getting them to turn off security features and install other harmful apps. Durak wasn't some sketchy off-label app that had to be sideloaded; it was in the official Google Play store. "67% of all malicious apps were downloaded from the Google Play store, while only 10% came from other third-party markets," he says. "People on Google Play rely on reviews from other users a lot to decide if an app is safe or not. This does not work." On the other hand, he says, "Apple carefully checks every app in its app store. This cuts down on the number of available apps, but it cuts down on the number of apps that are reported to be harmful by a lot."

SMS text messaging is another way that attackers get that all-important clickable link in front of their victims. This method uses a different set of social engineering tricks and is called SMS phishing or smishing. It catches both the gullible and the powerful.

Rasmus Holst, CRO of Wire, says that cybercriminals can use SMS phishing in different ways depending on what they want to do. "If the goal is to put malware on a device, there is usually a file attached along with a message that tries to get the user to click on it and download it. Cybercriminals can pretend to be someone they know and trust, like an employer or manager asking an employee to look at the attached document. This is a trap for a busy person who doesn't know what's going on. Jeff Bezos's phone was broken into two years ago after he downloaded one video file from a trusted contact. Hackers can sometimes get a malicious file onto a phone without the user's permission by using zero-day exploits of mobile browsers. All the user has to do is click on the link."

Malware

If a hacker can't get you to click a button and lower your phone's security without your knowledge, they might look for someone who has already jailbroken their phone. Many people think that jailbreaking lets users better customize their devices and install apps from unofficial sources. However, by its very nature, jailbreaking loosen the strict security sandboxing that keeps smartphones locked down.

"Hackers make apps that people want, like a free VPN , to download malware onto the devices of users who don't know what's going on," says David Schoenberger, founder and Chief Innovation Officer of Eclypses. "When these malicious apps are put on a device, they check to see if it has been rooted or jailbroken. If it has, they steal personal information and other sensitive data. Once a device has been jailbroken, the operating system is no longer safe. This makes it easy to get into passwords, chats, and other data entered by the user, such as bank or payment information."

Making excuses

Lastly, if the user doesn't want to give up control of their device, an attacker can go around them and get it from their mobile provider. You may remember the British media scandal from the middle of the 2000s when tabloids used what they called "blagging" to get into the mobile voicemail boxes of celebrities and people who had been victims of crimes. This method, which is also called "pretexting," involves an attacker gathering enough personal information about their victim to be able to talk to their phone provider as if they were the victim. This gives the attacker access to the victim's account.

The tabloids just wanted to get the latest news, but criminals can use the same methods to do even more damage. Adam Kohnke, Information Security Manager at the Infosec Institute, says, "If the attack is successful, the attacker convinces the phone carrier to move the victim's phone number to a device they own. This is called a SIM swap." "Calls, texts, and access codes, like the second-factor authentication codes your bank or financial provider send to your phone via SMS, now go to the attacker instead of you."

Getting in through Bluetooth

Hackers can get into phones through two types of wireless attack vectors that don't require anyone to give up permissions. Both methods require being close to the target, but they can sometimes be done in public places. "One of a smartphone's weak spots is the Bluetooth connection, and hackers often use special methods to connect to Bluetooth devices and hack them," says Aleksandr Maklakov, CIO at MacKeeper and a tech and security expert. "Because many people leave their Bluetooth connection on, this is a common way to break into a device. If there are no rules for a Bluetooth connection, hackers can get close to your phone and hack into it without you knowing."

Wi-Fi attacks by a "man in the middle"

A man-in-the-middle Wi-Fi attack is another type of wireless attack that could happen. Peter Baltazar, a cybersecurity expert and technical writer at MalwareFox.com, says that a lot of people connect their smartphones to free public Wi-Fi whenever they can. "This habit can cause a lot of trouble because hackers who are good at what they do can steal the connection and get into the phone." By listening in on communications, hackers can get a lot of information about a user's phone without ever taking control of it. (Communication that uses TLS 1.3 is much harder to spy on in this way, but that protocol hasn't been used everywhere yet.)

They broke in. What now?

What's the next step for an attacker who has used one of the above methods to get a foothold on a phone? Even though smartphone operating systems are based on Unix-like systems, Callum Duncan, director at Sencore Cybersecurity, says that an attacker who gets in will find a very different environment than on a PC or server.

"Most apps talk to the operating system and other apps through what are called API calls," he says. "Because the kernels for iOS and Android are so different from anything that would be similar to their Unix base, it would be almost impossible for them to share exploits. Both devices have command lines, but you can only use them if you have the highest level of privilege and can usually only get to them by rooting or jailbreaking the device."

But it's not impossible just because it's hard. Duncan says that this kind of exploitation does happen. "Privilege escalation would be key to this process, and getting around built-in safety mechanisms would be hard, but any attacker who can run code on a user's device is doing just that—running code on a user's device—so if they're smart enough, they could make that device do whatever they want."

Director of the Application Security Center of Excel lence at Coalfire, Caitlin Johanson, says that attackers who get a foothold on a device can access a surprising amount of sensitive data. "Apps that are installed create data stores like SQLite, which could have anything from web request and response content to cookies and potentially sensitive information," she says. "Common flaws in both iOS and Android include caching application data in memory (like authentication credentials) and keeping thumbnails or snapshots of the running app, which could store sensitive information on the device by accident. Most of the time, sensitive information is not encrypted and is stored right on the device in places like browser cookie values, crash files, preference files, and web cache content."

"The tools that were made for developers make it easier for an attacker to get this kind of data, interact with it, or even change it, like and on Android or iExplorer or plutil on iOS," she says. "Standard utilities can be used to look at any database files copied from the device, and if we need to decrypt, we can run scripts with tools like Frida to decrypt stored values."

Thicker than a brick

We don't want to make any of this sound too easy. Most people don't jailbreak their phones, click on phishing links, or give suspicious apps more permissions. Even when hackers do get into a device, the security features built into iOS and Android often stop them.

The best way to hack a smartphone is probably to want to do it more than any of the methods we've talked about here. "Attackers make highly repeatable and automated models that pick and prod at every angle of a mobile app or a new operating system version in the hopes of finding a weak point," says Hank Schless, Senior Manager of Security Solutions at Lookout. "Once they find a weakness that can be used to their advantage, they try to take advantage of it as soon as possible, before a fix is made."

And if you can't figure out how to break into a cell phone, well, maybe you can find a friend who can help. Schless says that most of the time, cybercriminals share information on the dark web or in groups on encrypted chat platforms like Telegram. "Larger groups, like those backed by nation-states, are encouraged to share code and exploits in the hopes that working together will make malicious campaigns more successful." The good guys need to share information as well because they have a lot of work to do.

There are hidden risks to giving out your phone number.

how to hack a mobile phone with phone number

This week, I saw a scary headline that said hackers got hold of people's phone numbers during a recent breach of consumer data. This was seen as a big and troubling piece of news.

I'm a digital visitor, which means I'm an old person. Unlike digital natives, I didn't come out of the womb into a world where everyone had a small, powerful computer in their pocket that was connected to the rest of the world and the internet. I like that the world is so connected, but sometimes it still feels strange to me.

But for a long time in my life, almost everyone who had a phone put their number in a public phone book so that everyone could find them. Except for a few people who were very careful or secretive, the phone number was known to everyone. It was silly to think that many people would worry that their phone numbers could be linked to their names.

If someone wanted to talk to you, all they had to do was look you up in the local phone book or call the phone company—there was only one—and ask for your number. How else would your school study partner or Aunt Emmy find you? You wanted people to know the number.

This dynamic hasn't gone away completely, especially in business. If they have a separate landline in the office, service providers often list both their cell phone numbers and office phone numbers so that clients can reach them. But for many people, their phone numbers are private information, and they would be upset if hackers got their hands on them. Should we be worried if hackers get our cell phone numbers, even if privacy isn't the main issue?

We should keep our phone numbers secret for practical reasons related to safety. The Vice article about the recent Robinhood hack that exposed phone numbers said, "Phone numbers are especially valuable to hackers because many services use SMS for two-factor authentication." If a hacker gets control of a victim's phone number, they might be able to send login verification codes to themselves instead of the victim. Or, if a hacker has the target's phone number, they can try to get their verification codes by sending phishing messages or calling them. This month, Motherboard reported on the booming underground trade of bots that make it easier to trick people into giving out personal information by calling them. There's more at stake than just avoiding spam calls or our less-than-favorite family members.

One obvious security risk is giving bad people access to your phone, which is much more likely if the hacker has your phone number. Hackers can send you a text message with a link to their website by using sophisticated spyware. Like other phishing attacks, clicking on the link could let the hacker take control of your phone and access its data. It could also let the hacker use your phone's microphone to listen in on nearby conversations or send texts directly from your phone.

Control of your phone can lead to control of your social media accounts, which are often linked to your phone number. This is less invasive but still upsetting. The bad person could pretend to be you on social media, watch your online relationships, and even damage them. Even giving up an old phone number can put you at risk of cyberattacks. When changing phone numbers, it might be a good idea to keep your old number and not give it back to the phone company. Instead, you could use a number parking service that will hold that number for you for a small fee. If you don't, your old number will go back into circulation after 45 days and could be used by someone else.

Most likely, online banking apps are the most important worry. People who use mobile apps to access their bank accounts could be putting those accounts at risk if the phone is hacked. Many crypto traders use mobile apps to manage their digital wallets and accounts. These traders could also lose their coins if someone stole their phone and started a crypto transfer. A criminal who knows your phone number can also get around the two-factor authentication that a financial services company needs to let into your account.

With an attack called "Sim-jacking," someone could take over your phone number completely. In this method, the phone owner is tricked into giving the bad guy a code, which gives the bad guy control over the phone number. So sim-jacking doesn't take a lot of technical knowledge, just the skills of a con artist. The Guardian says that the number of sim-jacking attacks in the UK has tripled since the pandemic began.

We should all be aware of the risks, but we don't want to make them seem worse than they are. People can follow you home from the store if they know your street address. If someone knows your email address, they can also use that against you. Just because a phone number is out in the open doesn't mean that someone is likely to attack. There are millions of phone numbers that criminals could use, but almost none of them will ever get the attention of a hacker.

It just helps to keep in mind that the small computers we carry can put us in danger and that knowing a phone number can cause more problems than annoying sales calls and texts.

Conclusion:

Hacking through a phone number is possible and you can do nothing about this attack the telecommunications and infrastructure services should take action to resolve this issue. You can only hope that the operator companies you use are not among those that take advantage of this vulnerability.
