Collaborating with Teams from Other Organizations and National CERTs
Investigating cybercrime is rarely an isolated effort
Large-scale attacks rarely affect a single organization in isolation; they're usually part of broader campaigns that impact multiple victims in the same sector or region, which makes collaboration with other affected organizations and with national CERTs, each country's reference incident response teams, decisive for understanding the true magnitude of a threat. Sharing indicators of compromise with other organizations, even direct competitors, lets the whole sector defend itself faster against an active campaign, and national CERTs usually act as trusted intermediaries that facilitate that exchange without directly exposing sensitive information between organizations that otherwise wouldn't cooperate. In practice, many organizations avoid reporting incidents for fear of reputational damage, but that reluctance ends up benefiting the attacker, who can reuse the same technique against other victims while the sector remains without visibility of a threat that's already actively circulating.
