Signs of unauthorized access detected in May on the network of the US Department of Homeland Security (DHS) were dismissed twice by analysts as insignificant and harmless activity. As a result of a review conducted in June, it was confirmed that the situation was an actual cyber breach.
The attacked network is the Homeland Security Information Network, which is used in security support processes for World Cup matches across the US. Despite suspicious activities being noticed in mid and late May, analysts concluded that this situation did not pose a security threat.
The incident once again highlighted how vital intelligence and assessment processes are in the security of critical infrastructures. Ignoring the initial signs delayed the detection of the breach by months.
