Recent assessments from intelligence agencies indicate a "global cyber campaign" involving hackers, likely gaining access to confidential information through deceptive methods. Dutch intelligence highlights that one of the most common tactics employed by cybercriminals is impersonating a 'Signal' support chatbot to trick users into revealing their security codes, giving hackers full control over their accounts.

Furthermore, the hackers try to connect to users' Signal and WhatsApp accounts using the 'linked devices' feature, which increases the risk of unauthorized access. Despite strong end-to-end encryption, the Dutch intelligence agencies caution that platforms like Signal and WhatsApp should not be relied upon for transmitting confidential or sensitive information, given the potential for such security breaches.

The situation underscores the ongoing threat posed by cybercriminals, particularly those with state affiliations, in exploiting vulnerabilities within popular communication apps. Users are advised to remain vigilant and adopt additional security measures to protect their accounts from such cyber intrusions.
