Few months back, the Windows Defender Advanced Threat Protection (Windows Defender ATP) research team noticed security alerts that captured an interesting attack pattern.
These alerts uncovered a well-planned, finely orchestrated cyberattack that targeted several high-profile technology and financial organizations with possible intentions of a cyberespionage campaign.
An unknown attacker was taking advantage of a silent yet effective attack vector: the compromised update mechanism or software supply chain for a third-party editing tool. We would discuss the scenarios observed and how this vector is quite effective for larger enterprise / business.
