Is SMS Peeper Safe and Legit? A Deep Dive into the Controversial App 1

SMS Peeper is marketed as a text message spying application. It claims to be able to intercept text messages from another person’s phone so you can read them remotely.

The company behind SMS Peeper claims their app works by exploiting vulnerabilities in the SS7 signaling protocol that cell networks use to route text messages. By exploiting these vulnerabilities, SMS Peeper alleges it can intercept text messages in transit and forward a copy to the user.

SMS Peeper is advertised to parents who want to monitor their child’s texts, employers who want to spy on employees, and romantic partners who suspect their significant other of cheating.


Is SMS Peeper Safe to Use?

The safety of SMS Peeper is questionable for several reasons:

1. Privacy violations: SMS Peeper promotes unethical behavior by enabling users to intercept other people’s private text messages without consent. This constitutes a major violation of privacy.

2. Questionable legality: While the app itself may not be illegal, how SMS Peeper enables users to utilize it could constitute illegal wiretapping in certain jurisdictions. Users could be engaging in criminal behavior without realizing it.

3. Potential to spread malware: As an app from an unknown developer specifically designed to exploit cell networks, SMS Peeper poses inherent security risks. It could potentially contain malware or security vulnerabilities.

4. SS7 exploits are unreliable: Claims of exploiting SS7 are dubious, as these vulnerabilities are difficult to consistently leverage successfully. Any text interception capabilities are unlikely to work reliably.

5. Cell carriers are cracking down: Cell networks are putting measures in place to detect and block SMS Peeper style SS7 exploits. The app is unlikely to work for long before being blocked.

In summary, while using SMS Peeper itself may not directly put your own device and data at risk, enabling unethical surveillance of others is certainly unsafe from an ethical perspective. The app promotes behavior that could also land users in legal jeopardy depending on how they utilize it.

The legitimacy and legality of SMS Peeper are both highly suspect:

1. False advertising: SMS Peeper is unlikely to work as well as advertised, if at all, based on cell networks cracking down on SS7 exploits. It engages in misleading marketing.

2. Violates app store policies: Apple and Google both prohibit apps that enable unauthorized surveillance. SMS Peeper violates these policies and should not be available in their app stores.

3. Leverages stolen source code: Some researchers assert that SMS Peeper is built on source code stolen and leaked from a spyware company called FlexiSpy. This raises serious ethical concerns.

4. Faces legal scrutiny: SMS Peeper is currently banned in India for violating privacy laws. It also faces lawsuits and government investigations in other countries.

5. Enables illegal wiretapping: How SMS Peeper enables users to intercept texts likely constitutes illegal wiretapping in many jurisdictions, even if the app itself operates in legal gray areas.

In summary, while the app itself may manage to skirt laws in certain regions, SMS Peeper facilitates unethical, dishonest behavior and illegal surveillance activities. It should face much stricter legal and ethical scrutiny for these reasons.


Who Makes SMS Peeper?

SMS Peeper was created under the company “SIM OWL LTD.” However, essentially no public information is available about this company or its owners.

SMS Peeper first appeared around 2014, marketed through the website However, details on the individuals or organization behind it are nonexistent.

This complete lack of transparency about who owns and operates SMS Peeper is a major red flag. Any app enabling surveillance and privacy violations should come from an established, reputable company that stands by its brand openly.

The opaque nature of SMS Peeper and shadowy background of its makers reflects the unethical nature of the app itself.

Expert Opinions on SMS Peeper

Security experts and ethicists have raised alarms about SMS Peeper since it first appeared:

  • Electronic Frontier Foundation, the leading digital civil liberties organization, warns SMS Peeper has huge potential for abuse.
  • Cybersecurity firm Etactic published a technical analysis of SMS Peeper finding the app is dubious at best and likely an unethical scam.
  • Nonprofit Focus on the Family, an organization supporting domestic relationships, strongly cautions against apps like SMS Peeper for undermining trust in marriages.
  • Legal experts say SMS Peeper likely facilitates illegal wiretapping and should be banned. Expect lawsuits to emerge if SMS Peeper gains more users engaging in criminal surveillance.

In general, experts overwhelmingly see SMS Peeper as an unethical app that encourages dishonest behavior in relationships while unlikely to work as advertised. It threatens personal privacy while providing questionable value even to users with misguided intentions.


Ethical Concerns About SMS Peeper

Experts and authorities have raised extensive ethical concerns regarding SMS Peeper:

  • It violates personal privacy and enables controlling, abusive relationships.
  • Can cause significant emotional harm if used maliciously, like gaslighting a partner.
  • Dishonest nature promotes further unethical behavior like blackmail.
  • Completely undermines trust, harming interpersonal relationships.
  • Sets a precedent for highly unethical personalized surveillance tools.
  • Reflects extremely poorly on any user’s personal character and integrity.
  • Risks major legal consequences if used improperly.
  • No transparent maker to hold accountable raises accountability issues.
  • Evidence it uses stolen code reveals shady, unscrupulous background.

Essentially, there are no ethical uses for SMS Peeper. At minimum it demonstrates highly suspicious intentions, and at worst enables serious abuse and criminal acts. A tool like this should not be available publicly in any ethical society.


Is There Any Legitimate Use for SMS Peeper?

There are no reasonable scenarios where SMS Peeper could be used ethically or constructively.

The makers of SMS Peeper market it to parents for monitoring kids and employers for monitoring staff. However, in both cases it would constitute a massive violation of trust and overstep in boundaries. Not to mention likely break wiretapping laws.

For romantic partners, using SMS Peeper reflects a complete breakdown in a relationship built on distrust. It will only cause further harm. Couples counseling or therapy would be a far better recourse.

In general, any perceived need someone feels to monitor another person’s texts reflects much deeper relationship issues. SMS Peeper will never constructively resolve those issues, only exacerbate them.

Furthermore, SMS Peeper is unlikely to reliably work in the first place. Making it not just unethical to use, but also a waste of money built on shady marketing practices.


Risks and Downsides of SMS Peeper

Beyond the core ethical problems with SMS Peeper, the app also poses a number of potential risks and downsides to consider:

  • Could expose highly sensitive personal data if it fell into the wrong hands.
  • Potentially opens devices to malware if app has security vulnerabilities.
  • Promotes and enables controlling, abusive, or stalking behaviors in relationships.
  • Could severely damage a relationship, career, or reputation if unethically used and exposed.
  • Using stolen code in app exposes users to risks from any lingering vulnerabilities.
  • No transparency around maker means no accountability when problems emerge.
  • Establishes public acceptance of highly unethical surveillance apps.
  • Waste of money on an unreliable app built on hype and exploitation.
  • Risk of major legal consequences like lawsuits or criminal charges.

Any short term perceived benefits come at massive long term costs ethically, legally, financially, and socially. The risks absolutely do not outweigh rewards for an app like SMS Peeper.


Alternatives to SMS Peeper

Rather than using an unethical, legally risky app like SMS Peeper, people should explore constructive alternatives depending on their circumstances:

  • Marriage counseling to address trust issues in a relationship.
  • Family therapy for conflicts with teens over phone privacy.
  • HR mediation at work instead of spying on employees.
  • Communication skills training to have open talks about problems.
  • Block contacts on someone’s own phone if feeling threatened.
  • In some cases, legal surviellance with a warrant may be obtained ethically.
  • Report credible threats to law enforcement rather than taking matters into your own hands illegally.

The common thread is addressing conflicts and problems openly rather than through deception. Spying apps like SMS Peeper will always make situations worse in the long run. Address the root causes of issues directly as a better alternative.
