Analysis | The Cybersecurity 202: Protest goes online in Minneapolis as city, police websites hit by cyberattacks

By Joseph Marks

The clash is now online in Minneapolis.
Cyberattacks struck city government and law enforcement computers as mass anger over the killing of George Floyd, a black man who died after a Minneapolis police officer pressed his knee into his neck, led to major protests there.
The operation, known as a denial of service attack, rendered websites for Minneapolis police and some city agencies inaccessible for hours by overwhelming them with a flood of web traffic. A similar attack struck state computer systems but was less effective.
The attacks demonstrate how hacker activists who are willing to skirt the law can frequently amplify protests against police and government. The sometimes-violent protests and clashes with police led to thousands of arrests in cities across the nation, including Washington and Atlanta.
“When a police website goes down, that’s flashy and it communicates something emotional,” M.R. Sauter, an assistant professor at the University of Maryland who wrote a 2014 book about denial of service attacks and digital activism, told me. “This is a type of protest theater, which is what a lot of street [protest] actions are. It’s just online.”
Sauter acknowledged that while some digital activism can go too far – and end up limiting the free flow of information to the public or impede police work – the Minneapolis attack was more acceptable because it communicated public anger at the police and local officials without seriously endangering anyone.
It doesn’t stop the police from doing normal operations or from communicating necessary things with the public,” Sauter said. “People rarely use homepages for necessary communications that don’t have a backup.”

Coronavirus is amplifying concerns about digital attacks hurting public access to information.  
The loss of city and police websites – even if temporary – could surge public anxiety, which is already high after days of protests, violence and property destruction. Especially if cyberattacks continue.
“We as a society have been rightly protesting these agencies but we also depend on them for public safety and we’ve got to be careful about that,” said Hardik Modi, an associate vice president at the cybersecurity firm NetScout who focuses on denial of service attacks.
People also might feel more anxious about a website going down now since the pandemic has made everyone far more dependent on the Internet. “With everyone working and studying from home, it’s especially impactful to lose access to services,” Modi said. “This [website] is a key means of disseminating information and they lost it for some period of time."
Denial of service attacks have become increasingly common component of protests against police brutality. 
Hackers used such attacks in 2014 to take down police websites in Ferguson, Mo., after the police shooting of Michael Brown, an unarmed black teenager.
Another denial of service attack in 2015 took down local government sites in Baltimore after Freddie Gray, a black man, died after suffering a spinal injury while riding in the back of a police van.
Launching such attacks also carries heavy criminal penalties. Last year, for example, a man was sentenced to six year in prison for launching denial of service attacks against city government and police websites in Akron, Ohio.

Denial of service attacks are common largely because they’re incredibly easy to launch.
Minnesota Gov. Tim Walz (D) described the attack on state computers as “very sophisticated” and “not somebody sitting in their basement.” But, in fact, such attacks require little skill. That's largely because the perpetrators don't have to actually hack into any computer or websites, just pummel them with web traffic.
In most cases, people who organize the attacks simply pay nefarious online groups to launch them – usually using the computing power from thousands of hacked computers whose users don’t realize they’ve been compromised.
There have been some instances of prominent and damaging denial of service attacks, such as a 2007 attack on Estonian government computers that's often attributed to Russia and a 2012 attack on U.S. financial systems that officials blamed on Iran. But cybersecurity pros have become far better at defending against such attacks in recent years.
These attacks are extraordinarily unsophisticated,” Robert Graham, owner of the cybersecurity firm Errata Security, told me. “Within a minute you can take down someone's website.”
Such attacks often seem sophisticated to victims because they lacked digital protections that could have prevented or mitigated them, Graham said on Twitter.
The "sophisticated" cyber attack is a cliche, a trope, used to disguise the victim's own ineptness. It's not us that is so stupid, but them that is so sophistimicated.

It’s also often very easy for victims to recover from denial of service attacks, evidenced by the fact the Minneapolis Police Department came back online so quickly.
“It’s a form of protest but it's not a very effective one,” Graham said.
No groups have officially taken credit for the Minnesota attacks.
Social media sites affiliated with the hacktivist collective Anonymous, however, have threatened retribution against Minneapolis police. They also pledged to “intervene if and when it becomes necessary” after President Trump claimed he will label the far-left “antifa” movement as a terrorist group. “Trump cannot, for practical and legal reasons, formally designate antifa a terrorist organization, and neither he nor his attorney general has made public specific evidence that the far-left movement is orchestrating the fiery protests that have erupted in dozens of U.S. cities,” my colleagues Matt Zapotosky, Robert Klemko and Jacqueline Alemany report.
And because denial of service attacks are so easy, the list of possible perpetrators is nearly endless. 
“Anyone upset about [the Floyd killing], which is millions of people could push a button and do this,” Graham said.

The keys

The move suggests the National Security Agency may be getting more aggressive in countering Russian hacking as the 2020 election approaches, Julian Barnes and David Sanger at The New York Times report.
The alert focused on the same military intelligence unit that intelligence officials say was responsible for  hacks against the Democratic National Committee and the Hillary Clinton campaign in 2016. The agency did not disclose any victims of the hacking campaign, which targeted email servers, but said it began in August 2019. A fix for the bug the Russian hackers exploited was issued 11 months ago but hackers are still attacking systems that haven't been updated with the fix, the NSA says.
Investigators knocked down Georgia Gov. Brian Kemp's accusations that Democrats hacked state voter registration systems.

Kemp (R) accused the Democratic party of hacking the systems two days before the 2018 election. But an investigation found Kemp, who was the state’s top election official at the time, “mistook planned security tests and a warning about potential election security holes for malicious hacking,” The Atlanta Journal-Constitution and ProPublica report.
The state investigator's report shows there was no "evidence of damage to (the secretary of state’s office’s) network or computers, and no evidence of theft, damage, or loss of data."
The suspicious Internet activity Kemp's office described was a scan by the Department of Homeland Security that Kemp's office had agreed to three months earlier. The investigation also confirmed that the state's voter information page had  a significant security hole that Kemp's office has never publicly acknowledged.

China hawks have pointed to the semiconductor industry as key to reducing U.S. companies' reliance on Chinese hardware that could be used for government spying. The White House and lawmakers from both parties have introduced plans that would boost government spending on the industry.
Last month the White House moved to block overseas sales of chips produced with U.S. technology to Huawei and other Chinese firms that represent national security risks.

Global cyberspace

Pyongyang officials also accused the Trump administration of using the allegations as leverage in stalled denuclearization talks, Reuters reports. U.S. officials have accused North Korean government hackers of digitally stealing money from banks and ATMs in order to help fund the government.
“We want to make it clear that our country has nothing to do with the so-called ‘cyber threat’ that the U.S. is talking about,” North Korea’s Foreign Ministry said.

Germany's foreign ministry called in the Russian ambassador in Berlin on Thursday to complain "in the strongest possible terms" about a hack attack on the German lower house of parliament in 2015 and discuss possible sanctions against those responsible.

Analysis | The Cybersecurity 202: How the shutdown could make it harder for the government to retain cybersecurity talent

By Joseph Marks 13-17 minutes THE KEY President Trump delivers an address about border security amid a partial government shutdown on Jan. 8. (Carolyn Kaster/AP) The partial government shutdown that's now in its 18th day is putting key cyber policy priorities on hold and leaving vital operations to a bare bones staff. But the far greater long-term danger may be the blow to government cyber defenders' morale, former officials warn. With the prospect of better pay and greater job security in the private sector, more government cyber operators are likely to decamp to industry, those former officials tell me, and the smartest cybersecurity graduates will look to industry rather than government to hone their skills. That’s especially dangerous, they say, considering the government’s struggle to recruit and retain skilled workers amid a nationwide shortage of cybersecurity talent. About 20 percent of staffers are furloughed at the De

Democrats call for investigation into Trump’s iPhone use after a report that China is listening:Analysis | The Daily 202 I The Washington Post. By James Hohmann _________________________________________________________________________________ President Trump and Chinese President Xi Jinping visit the Great Hall of the People in Beijing last November. (Andrew Harnik/AP) With Breanne Deppisch and Joanie Greve THE BIG IDEA: If Democrats win the House in two weeks, it’s a safe bet that one of the oversight hearings they schedule for early next year would focus on President Trump’s use of unsecured cellphones. The matter would not likely be pursued with anywhere near the gusto that congressional Republicans investigated Hillary Clinton’s use of a private email server during her time as secretary of state. Leaders of the minority party have higher priorities . But Democratic lawmakers made clear Thursday morning that they will not ignore a New York Times report that Trump has refused to stop using iPhones in the White House, despite repeated warnings from U.S. intelligence offici
