Authorities are investigating interference with police radio networks, websites and communications employed by law enforcement in addition to other officials during recent US protests through the death of George Floyd in Minneapolis.
Even so the efforts to disrupt police radios and destroy websites in Illinois, Minnesota and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that police force should be ready for such tactics as protests continue.
Authorities have not really identified anyone responsible or provided information regarding what sort of disruptions were conducted. But officials were particularly concerned by interruptions to police radio frequencies over the past weekend of May as dispatchers attempted to direct responses to large unrest and protests that overshadowed peaceful demonstrations.
During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the US Department of Homeland Security.
Dallas police did not improve with questions regarding the incident.
The assessment, which had been obtained through the Associated Press, attributes the Dallas disruption to “unknown actors” and will not say the way they accessed the radio frequency. It warned that attacks of numerous types would likely persist.
“Short-term disruptive cyber activities based on protests probably continues – various actors may very well be completing these operations – while using possible ways to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.
The assessment noted similar difficulty with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 together with reports of theft, vandalism and arson. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”
Police throughout the country have encrypted their radio communications, often arguing that it’s methods to protect officers and block criminals from listening in on accessible phone apps that broadcast police radio channels. But media outlets and local hobbyists have been annoyed by the modifications, which prevent them from reporting on issues regarding public safety.
The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.
Police force agencies have been targeted by online pranksters or hackers nowadays, including by some who claimed to remain motivated by on-the-ground protests against police tactics. For instance, the hacking collective Anonymous claimed responsibility to your defacement of local police departments’ websites in 2012 as protesters clashed with officers within the Occupy Wall Street movement.
Those who self-recognized as being a member of the collective also claimed to get accessed dispatch tapes besides other Ferguson Police Department records in 2014 right after a white police officer shot and killed Michael Brown, an 18-year-old black man.
Like other government entities, police force agencies these days happen to have been frequently targeted by ransomware attacks, wherein a perpetrator virtually locks up a victim’s computer files or system and demands payment to discharge them.
The prevalence of cyberattacks – that will cause physical damage or far-reaching disruption – and much less severe online trickery, such as stealing passwords, has given police force agencies more experience at fending off efforts to accept down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to take care of, said Morgan Wright, chief security officer for your cybersecurity company SentinelOne.
“The biggest concern they offer right away is considered the safety within their communities, the safety of their own officers,” Wright said of how police force agencies view cyberthreats amid large demonstrations and unrest. “But any time you look into what underpins everything we use to collaborate, operate and communicate, it’s all technology.”
A handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov, as large protests gathered steam after the May 25 death of Floyd. Tim Walz said state networks appeared to be targeted. He described the activity as a good “a very sophisticated denial of service attack.”
But experts said the strategy of bombarding a website with traffic is common and doesn’t always get a higher level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.
But the efforts got a considerable amount of attention, partly due to unverified online claims that Anonymous was responsible after many years of infrequent activity. The decentralized group largely went quiet in 2015 but still is known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.
Twitter users also made unverified claims that Anonymous was behind recent intermittent outages within the city government’s website on the Texas capital of Austin. Their posts indicated that the disruption was retribution for law enforcement officers shooting a 20-year-old black man through the head having a beanbag in a May 31 protest away from police headquarters.
The injured protester, recognized by family as Justin Howell, remained hospitalized Wednesday in critical condition.
A spokesman said Monday that he couldn’t provide any information about the cause, although the city’s IT department was looking into the site’s issues. He stated the web page was still experiencing a higher quantity of traffic.
“You needs to have expected us,” an account purporting to end up being Anonymous’ posted on Twitter. Moreover it warned that “new targets are coming soon.”
The collective’s approach – you can act in name – helps make it tough to verify the current claims of responsibility. But Twitter accounts long associated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal having studied the Anonymous movement for decades.
Individuals with sophisticated and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that form of activity will resume, she added.
“There’s many things going on in your background, citizens are chatting,” Coleman said. “Whether or otherwise not it materializes can also be a question. But certainly many people are variety of talking and arousedconnecting and talking.”
