In some countries, it is particularly important for journalists and regime critics to pay attention to the security of their smartphones. They are often the enemy, as they use the power of information to exert pressure on ruling systems. They must protect not only themselves but also their sources. Authoritarian regimes use targeted surveillance measures to spy on journalists, intercept their communications or track their contacts. Smartphones are an easy target as they offer many opportunities for surveillance. A lack of protection can lead to confidential research being compromised or those affected themselves being exposed to arrest, intimidation or even physical danger. It is therefore essential to use encryption, anonymization tools and secure communication methods in this context.
