US Cybersecurity Officials See Mainly Low-Impact Attacks From Logging Flaw

The US company charged with defending the nation towards hacking mentioned on Tuesday the vast majority of assaults it has seen utilizing a just lately disclosed flaw in extensively used open-source software program have been minor, with lots of them in search of to hijack computing energy to mine cryptocurrency.
