Citizens should consider the potential dangers before installing a number-identification app on a smartphone to flag spam or scam calls, because some of these tools can pose serious threats to personal data. Vladimir Ulyanov, head of the Zecurion analytical center, discussed the risks with socialbites.ca, highlighting how such software can affect privacy and device security.
“When an app is installed, it often demands access not only to the contact list but also to messages, files and documents, photos and videos, the microphone, location data, and information about how the app itself operates”, he noted. Ulyanov emphasized that data gathered by these programs can end up not only with the developers but also with third parties, depending on the app’s data-sharing policies and the presence of any agreements with data processors.
He advised users to weigh whether granting broad permissions to a spam-detection app is worth the potential benefits. The expert pointed out that the highest risk is associated with apps that have few installations, have recently appeared in app stores, or are sourced from third parties, as these are more likely to mismanage data or be less transparent about data flows.
According to Ulyanov, phone-based caller ID and spam filtering should be viewed as an extra layer of protection rather than a primary safeguard. He also cautioned that the accuracy of identifying incoming calls is unlikely to reach perfect levels, and users should not rely on it as a sole defense against unwanted calls or fraud.
Recent warnings for Android users stress the importance of cautious app selection and ongoing vigilance against evolving threats. In practice, staying informed about permissions, reviewing app updates, and using native safety features can help users maintain a balance between helpful spam protection and robust data privacy.
