Poland directs officials to ditch Signal in favor of 'secure' state-developed alternative

The Polish government is urging public officials to stop using Signal and switch to a state-developed alternative called mSzyfr Messenger due to security risks. The government cited social engineering attacks and phishing campaigns conducted by advanced persistent threat groups as reasons for the change. mSzyfr Messenger is designed for use by public administration entities and relies on multi-factor authentication provided by US companies.
