  As the landscape of time-sensitive applications gains prominence in 5G/6G
communications, timeliness of information updates at network nodes has become
crucial, which is popularly quantified in the literature by the age of
information metric. However, as we devise policies to improve age of
information of our systems, we inadvertently introduce a new vulnerability for
adversaries to exploit. In this article, we comprehensively discuss the diverse
threats that age-based systems are vulnerable to. We begin with discussion on
densely interconnected networks that employ gossiping between nodes to expedite
dissemination of dynamic information in the network, and show how the age-based
nature of gossiping renders these networks uniquely susceptible to threats such
as timestomping attacks, jamming attacks, and the propagation of
misinformation. Later, we survey adversarial works within simpler network
settings, specifically in one-hop and two-hop configurations, and delve into
adversarial robustness concerning challenges posed by jamming, timestomping,
and issues related to privacy leakage. We conclude this article with future
directions that aim to address challenges posed by more intelligent adversaries
and robustness of networks to them.
