Cloudflare CEO says crypto exchanges are a popular target for cyber attackers

The experts reviewed studies of the vaccines' performance and concluded the shots are working well despite the extra-contagious delta variant, especially against severe disease.

“Even in populations with fairly high vaccination rates, the unvaccinated are still the major drivers of transmission" at this stage of the pandemic, they concluded.

The opinion piece, published in The Lancet, illustrates the intense scientific debate about who needs booster doses and when, a decision the U.S. and other countries are grappling with.

After revelations of political meddling in the Trump administration’s coronavirus response, President Joe Biden has promised to “follow the science.” But the review raises the question of whether his administration is moving faster than the experts.

The authors include two leading vaccine reviewers at the Food and Drug Administration, Drs. Phil Krause and Marion Gruber, who recently announced they will be stepping down this fall. Among the other 16 authors are leading vaccine researchers in the U.S., Britain, France, South Africa and India, plus scientists with the World Health Organization, which already has urged a moratorium on boosters until poor countries are better vaccinated.

In the U.S., the White House has begun planning for boosters later this month, if both the FDA and Centers for Disease Control and Prevention agree. Advisers to the FDA will weigh evidence about an extra Pfizer shot Friday at a key public meeting.

Georgetown University's Larry Gostin said the paper “throws gasoline on the fire” in the debate about whether most Americans truly need boosters and whether the White House got ahead of scientists.

“It’s always a fundamental error of process to make a scientific announcement before the public health agencies have acted and that’s exactly what happened here,” said Gostin, a lawyer and public health specialist.

The FDA did not respond to requests for comment Monday morning.

The U.S. already offers an extra dose of the Pfizer or Moderna vaccines to people with severely weakened immune systems.

For the general population, the debate is boiling down to whether boosters should be given even though the vaccines are still offering high protection against severe disease — possibly in hopes of blocking milder “breakthrough” infections among the fully vaccinated.

Last week, CDC Director Dr. Rochelle Walensky said new data showed that as delta surged, the unvaccinated were 4.5 times more likely than the fully vaccinated to get infected, over 10 times more likely to be hospitalized and 11 times more likely to die. Still, government scientists are also weighing hints that protection is waning among older adults who were vaccinated early last winter.

The writers of Monday's commentary reported reviewing worldwide studies since delta began surging, mostly of U.S. and European vaccines. The team concluded “none of these studies has provided credible evidence of substantially declining protection against severe disease.”

Because the body builds layers of immunity, gradual drops in antibody levels don't necessarily mean overall effectiveness is dropping "and reductions in vaccine efficacy against mild disease do not necessarily predict reductions in the (typically higher) efficacy against severe disease,” they wrote.

The more the virus spreads, the more opportunity it has to evolve into strains that could escape current vaccines. The Lancet reviewers suggest there could be bigger gains from creating booster doses that better match circulating variants, much like flu vaccine is regularly updated, than from just giving extra doses of the original vaccine.

“There is an opportunity now to study variant-based boosters before there is widespread need for them,” the scientists wrote.

Cloudflare CEO says crypto exchanges are a popular target for cyber attackers

Ars Technica 13 September, 2021 - 06:47pm

"The old adage is, Why do bank robbers rob banks? It's because it's where the money is," Prince said in an interview on "Mad Money." "One of the biggest places that cyber attackers are going after right now are the various cryptocurrency exchanges and other cryptocurrency parts of the universe."

Cryptocurrencies attracted attention in connection to cyber crimes earlier this year after high-profile ransomware attacks, most notably the Colonial Pipeline incident in May that temporarily disrupted fuel supply in parts of the East Coast.

Colonial Pipeline ended up paying $5 in ransom one day after its IT network was hacked, although U.S. law enforcement officials were able recover nearly half of the bitcoin that the criminal cybergroup received.

The events ignited debate around the role that the blockchain-based digital currencies play in the rise of ransomware attacks. Some argue that cryptocurrencies enable ransomware incidents, while others say the fact transactions are recorded on public ledgers can be helpful in solving cyber crimes.

Cloudflare, which went public two years ago, offers web network infrastructure to companies, allowing them put their content online. Cloudflare also provides security services to prevent what are known as distributed denial of service attacks.

Some of its clients are cryptocurrency exchanges, Prince said, giving the company a "front-row seat" to the evolving cyber threats they face. "We're watching more and more innovation from attackers in that space, but we are staying ahead of it," he added.

Prince's comments Monday came in response to a question from Cramer, who asked whether the executive would feel safe investing through a crypto exchange that is a Cloudflare customer. Cramer, who has invested in cryptocurrencies, told Prince he's personally concerned "there will be a hack and my money will vanish."

"We're proud of the fact that we've kept the cryptocurrency customers that are ours secure and safe and helped augment the additional protections that they have in place," Prince told Cramer. "I'd feel safe using any of the cryptocurrency exchanges that uses Cloudflare today."

CNBC has reported previously on individual crypto investors who had their Coinbase accounts hacked.
