""This is the largest impact on the energy system in the United States we've seen from a cyberattack, full stop," says Rob Lee, CEO of the critical-infrastructure-focused security firm Dragos. Aside from the financial impact on Colonial Pipeline or the many providers and customers of the fuel it transports, Lee points out that around 40 percent of US electricity in 2020 was produced by burning natural gas, more than any other source. That means, he argues, that the threat of cyberattacks on a pipeline presents a significant threat to the civilian power grid. "You have a real ability to impact the electric system in a broad way by cutting the supply of natural gas. This is a big deal," he adds. "I think Congress is going to have questions. A provider got hit with ransomware from a criminal act, this wasn't even a state-sponsored attack, and it impacted the system in this way?""

"As hospitals face a surge in patients and critical equipment shortages stemming from the coronavirus pandemic, they are increasingly becoming the target of hackers who see health care facilities as easy prey. Ransomware attacks, in which hackers lock up a network and demand payment to return access to these systems, have presented a growing threat to hospitals since January. "

"Dye told the Wall Street Journal that hackers increasingly use novel methods and bugs in the software of computers to perform attacks, resulting in about 55% cyberattacks going unnoticed by commercial antivirus software."

"At 221 of the Fortune 500 companies, Fortune magazine's list of the the top 500 U.S. public corporations ranked by gross revenue, employees' credentials are posted publicly online for hackers to steal and reuse in cyberattacks, according to new research from the web intelligence firm Recorded Future. "

"Victims of a major ransomware cyberattack that has spread through the US and Europe can no longer unlock their computers even if they pay the ransom. The "Petya" ransomware has caused serious disruption at large firms including the advertising giant WPP, French construction materials company Saint-Gobain and Russian steel and oil firms Evraz and Rosneft. Infected computers display a message demanding a Bitcoin ransom worth $300. Those who pay are asked to send confirmation of payment to an email address. However, that email address has been shut down by the email provider. "

"His program became the first of a particular type of cyber attack called "distributed denial of service," in which large numbers of internet-connected devices, including computers, webcams and other smart gadgets, are told to send lots of traffic to one particular address, overloading it with so much activity that either the system shuts down or its network connections are completely blocked."

"If mediocre malware can power some of the largest DDoS attacks ever, and considering the sad state of security of the Internet of Things in general, we should probably brace for more cyberattacks powered by our easy-to-hack "smart" Internet of Things, as many, including ourselves, had predicted months ago."

"It's been said that software is "eating the world." More and more, critical systems that were once controlled mechanically, or by people, are coming to depend on code. This was perhaps never clearer than in the summer of 2015, when on a single day, United Airlines grounded its fleet because of a problem with its departure-management system; trading was suspended on the New York Stock Exchange after an upgrade; the front page of The Wall Street Journal's website crashed; and Seattle's 911 system went down again, this time because a different router failed. The simultaneous failure of so many software systems smelled at first of a coordinated cyberattack"

"Hultquist noted that cyberwarfare evens the battlefield between Iran and the US. "That's why they choose an asymmetric battleground," he said. "We might have this massive advantage with a very sophisticated ability, but we also have this very sophisticated society that makes us very vulnerable to computer attacks.""

"Biden's team is more vulnerable to cyberattacks "

"Re/code, a technology news website, was the first to float the North Korea theory last Friday. Citing unnamed sources familiar with the matter, it said: "Sony Pictures Entertainment is exploring the possibility that hackers working on behalf of North Korea, possibly operating out of China, may be behind a devastating attack that brought the studio's network to a screeching halt earlier this week … The sources stress that a link to North Korea hasn't been confirmed, but has not been ruled out, either.""

"Major Wall Street institutions were cracked wide open by a phishing scam from FIN4, a hacker group that, unlike its competition, can write convincingly and employs some basic smarts about why people open attachments."

"In a statement, the company said: "Colonial Pipeline is taking steps to understand and resolve this issue. At this time, our primary focus is the safe and efficient restoration of our service and our efforts to return to normal operation. This process is already under way, and we are working diligently to address this matter and to minimize disruption to our customers and those who rely on Colonial Pipeline."

"Ukraine has been hit by a "massive" cyber-attack, with the websites of several government departments including the ministry of foreign affairs and the education ministry knocked out. Officials said it was too early to draw any conclusions but they pointed to a "long record" of Russian cyber assaults against Ukraine, with the attack coming after security talks between Moscow and the US and its allies this week ended in stalemate."
