Multiple reports say that Iran's government has indicated that it's succeeded in fending off another cyberattack. Tehran is again being tight-lipped about the incident, beyond saying that it successfully defended itself, and that the target was "electronic government systems." There's been some a priori speculation about the usual adversaries in the press, but as the BBC points out, Iran's Telecommunications Minister was more specific, saying that the attack used tools associated with APT27, a Chinese-speaking threat group. The Islamic Republic News Agency quotes the ministry as characterizing the attack as "foreign spying."

Around mid-day Friday more cyberattacks hit Louisiana. The City of New Orleans was most prominently affected by what BleepingComputer says has been tentatively identified as (again) Ryuk ransomware. CNN reports that the city declared a state of emergency and disconnected systems from the Internet as a precautionary measure. Emergency services are said to have been unaffected, and City Hall is open for business today, as New Orleans officials characterize the effects of the attack, WBRZ says, as "minimal." In addition to New Orleans, there are reports in WBRZ that sheriff's offices in three Louisiana parishes, Rapides, Washington, and Orleans, were also subjected to an attack at the end of last week. It's unclear whether these attacks are related.
