The profile of attacks on two US state voter registration systems this summer presented in an FBI “Flash” memo suggests that the states were hit by a fairly typical sort of intrusion. But an Arizona official said that the Federal Bureau of Investigation had attributed an attack that succeeded only in capturing a single user’s login credentials to Russian hackers and rated the threat from the attack as an “eight on a scale of ten” in severity. An Illinois state official characterized the more successful attack on that state’s system as “highly sophisticated” based on information from the FBI.
