CISA Alerts Public to Rising Attacks on Mobile Messaging Apps
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) is warning that hackers are increasingly targeting people who use popular mobile messaging apps, such as Signal, WhatsApp, and Telegram.
According to CISA, cybercriminals are using sneaky tricks and fake apps to gain access to users’ accounts and steal sensitive information. The attacks are aimed at high-profile individuals, including government officials, military personnel, and leaders of civil society organizations, in the U.S., Europe, and the Middle East.
Some recent examples include:
- Hackers taking over Signal accounts by exploiting its “linked devices” feature.
- Fake apps targeting users in the Middle East to steal data from Android phones.
- Scams in Russia using fake versions of popular apps like WhatsApp and TikTok.
- Small-scale attacks on iPhones and WhatsApp users through security flaws.
- Malware targeting Samsung Galaxy phones in the Middle East.
CISA recommends people protect themselves by using secure messaging, strong passwords, two-step authentication (not via SMS), updating their apps and phones regularly, and being cautious of links or apps from unknown sources.
For iPhone users, turning on Lockdown Mode and reviewing app permissions can help. Android users should choose phones from trusted brands, enable security features in browsers, and carefully manage app permissions.
CISA stresses that taking simple precautions can significantly reduce the risk of these attacks.
