1. Begin the SURVEY
Twenty subjective questions ask about your phone’s symptoms.

Upon completion, a preliminary THREAT LEVEL is computed. Results are interpreted as LOW (0-33%), MEDIUM (34-66%), or HIGH (67-100%).

2. Begin the ANALYSIS
These tests objectively measure activity within your phone, while it is not in use.
SURVEY and ANALYSIS results are combined to produce a final THREAT LEVEL.

3. The eBook “Is My Cell Phone Bugged?” is embedded in the SpyWarn™ app.

Welcome to SpyWarn™, a forensic investigation anyone can conduct to evaluate the likelihood a smartphone is infected with illegal surveillance spyware.

Spyware is malicious software (malware) installed on smartphones, unbeknownst to the owner. Spyware is designed to allow some (or all) of the following unauthorized activities…

• Steal contact lists.
• Send fake messages.
• Receive text messages.
• Make the phone dial someone.
• Access smartphone voice mails.
• Send texts using a fake number.
• Track using the phone’s GPS capabilities.
• Receive a text revealing the length of calls.
• Receive a text alert whenever the phone is in use.
• Eavesdrop by remotely activating the microphone.
• Obtain a log of the phone numbers called, and who called in.

This app is not designed to detect simple adware spying by marketers.

This combination of subjective observations and quantifiable technical data produces the most accurate indication of your phone being infected with spyware.

Making a determination that your phone is bugged with spyware is initially a matter of observation. Murray Associates has identified the top 20 warning clues that spyware is present on a mobile phone. All of these clues are fairly easy to observe.

Keep in mind that some clues may also reflect issues other than spyware—your battery dying prematurely simply because it has reached the end of its life span, for example. However, the more warning clues you notice, the more likely your phone is infected.

Answer the questions as well as you can. You may pause whenever you want, and you can change your answers during the test. Once all questions are answered to your satisfaction, press the COMPUTE button.

A preliminary THREAT LEVEL (0-100%) will appear.

The likelihood of your phone being infected with spyware is generally interpreted as LOW (0-33%), MEDIUM (34-66%), or HIGH (67-100%). The latest computation is stored on the METER.

Data being analyzed during this test includes: the amount of time the phone is transmitting; and the amount of data being sent and received. The battery is also being monitored during the ANALYSIS. Unusually sharp battery charge drops when the phone is not otherwise being used is another clue spyware is at work behind the scenes.

The ANALYSIS may be conducted in different increments of time. The longer the test is run, the better the chances are you will detect spyware at work, and real-time eavesdropping.

The results of the ANALYSIS are also reported as a THREAT LEVEL percentage. This result is averaged in with the SURVEY THREAT LEVEL, thus providing the most accurate indication of spyware having infected your phone.

This file stores the results for future reference and comparison. These records may be accessed at any time.
Conduct ANALYSIS on a regular basis when your phone is spyware free. This creates a profile of your phone under normal operating conditions. Should a spyware Trojan infect your phone later, the latest ANALYSIS will be an anomaly by comparison.
