The New York Times says, in a largely anonymously sourced piece, that the US has staged implants in the Russian electrical grid to enable the US to impose costs on widely expected Russian misbehavior during the 2020 elections. This would be battlespace preparation as opposed to an attack (the article is clearer on this point than is its headline). The reported operation would appear to be a deterrent move intended to dissuade Russia from cyberattacks and influence operations against the US. 

Precedent for active cyber operations may be seen in US response to Russian election influence operations in 2018. (See Lawfare's useful summary of presumed Cyber Command action against the troll-farming Internet Research Agency, which President Trump more-or-less confirmed in a Fox interview.) Others see similarities to the allegedly planned but apparently never executed NitroZeus operation designed for use against Iran.

South America has largely recovered from widespread weekend power failures. Argentina and Uruguay were most heavily affected, with outages also felt in Brazil, Chile, and Paraguay.  Reuters notes that investigation is still in its earliest stages, but remarks by Argentina's energy secretary suggest that what's unprecedented here is the extent of the failure, not its causes. So speculation about a cyberattack is premature.

A European Commission report Friday accused Russia's government of an extensive social media effort to influence EU election results.

Target has recovered from its weekend point-of-sale disruption. The retailer says the incident was an accident, not a cyberattack.
