Late Friday and into the weekend what's thought to be a group of hacktivists defaced Iranian and Russian websites with a crudely rendered American flag and the message, "Don't mess with our elections." The defacements were relatively crude (the flag is old-school skid-work ASCII art, for one thing) but disruptive nonetheless.
The hackers exploited the recently disclosed Cisco CVE-2018-0171 Smart Install vulnerability to reset routers to their defaults and display their message. Most observers are so far inclined to accept the hackers' claims at face value—patriots who took advantage of unpatched routers to mess with Russia and Iran.
The Cisco vulnerability has been exploited elsewhere, not just in Russia and Iran (and not just for hacktivist purposes), since it became known.
As Facebook prepares to face its inquisitors on Capitol Hill this week, the platform's recent upgrades get generally poor reviews. The company has suggested more data misuse may come to light.
Britain's NCSC warned late last week that Russian actors were harvesting NT LAN Manager credentials in apparent preparation for an attack on the UK's critical infrastructure.
Sergey Skripal, former GRU officer and MI6 spy, victim of an attempted assassination with the Novichok nerve agent, has regained consciousness and is out of critical condition. His daughter Yulia, also out of critical condition, has refused to talk to the Russian consulate that sought to check on her welfare. British sources say the Skripals may be relocated with new identities to one of the other Five Eyes (probably the US).
