Early signs COVID-19 vaccines may not stop Delta transmission, England says
  • The US Center for Disease Control and Prevention has also raised concerns that vaccinated people infected with Delta could readily transmit it

LONDON: There are early signs that people who have been vaccinated against COVID-19 may be able to transmit the Delta variant of the virus as easily as those who have not, scientists at Public Health England (PHE) said on Friday.
The findings chime with those from the US Centers for Disease Control and Prevention, which last week raised concerns that vaccinated people infected with Delta could, unlike with other variants, readily transmit it.
The highly infectious Delta variant has become the dominant coronavirus type globally, sustaining a pandemic that has already killed more than 4.4 million people, including over 130,000 in Britain.
Vaccines have been shown to provide good protection against severe disease and death from Delta, especially with two doses, but there is less data on whether vaccinated people can still transmit it to others.
“Some initial findings ... indicate that levels of virus in those who become infected with Delta having already been vaccinated may be similar to levels found in unvaccinated people,” PHE said in a statement.

“This may have implications for people’s infectiousness, whether they have been vaccinated or not. However, this is early exploratory analysis and further targeted studies are needed to confirm whether this is the case.”
PHE said that of confirmed Delta cases that had ended up hospitalized since July 19, 55.1 percent were unvaccinated, while 34.9 percent had received two doses of a COVID-19 vaccine.
Nearly 75 percent of the British population has had two vaccine doses, and PHE said that “as more of the population gets vaccinated, we will see a higher relative percentage of vaccinated people in hospital.”
Separately, PHE said another variant, known as B.1.621, first detected in Colombia, had shown signs of evading the immune response triggered by either COVID-19 vaccines or previous infection.
PHE has labelled the variant “under investigation” but has not declared it a “variant of concern” — a designation that can trigger strong policy responses.
“There is preliminary laboratory evidence to suggest that vaccination and previous infection may be less effective at preventing infection with (B.1.621),” it said, adding there had been 37 confirmed cases of the variant in England.
“However, this data is very limited and more research is required. There is no evidence to suggest that (it) is more transmissible than the dominant Delta variant.”

Eswatini bans protests as African mediation begins

Eswatini bans protests as African mediation begins
  • At least 30 health workers were treated for gunshot injuries, the nurses’ union said
  • At least 30 people have died since June in some of the worst unrest in the southern African country’s history

MANZINI, Eswatini: Africa’s last absolute monarchy Eswatini on Thursday banned protests as regional mediators landed in the kingdom amid rumbling pro-democracy demonstrations.
A demonstrator died in hospital on Thursday from gunshot wounds suffered the day before when security forces opened fire on a protest, according to unions.
At least 30 health workers were treated for gunshot injuries, the nurses’ union said.
Railways workers led new protests on Thursday in the kingdom formerly known as Swaziland.
“Due to the spate of violent cases during protests, I have stopped all city and town municipals from issuing permits to hold protests,” Public Works Minister Prince Simelane told a news conference.
Internet access was limited, with Facebook completely shut off for a second day.
“Images that are coming from Eswatini are very disturbing indeed, and we can see that the political temperature is very hot,” Jeff Radebe, head of the mediators sent to the country by the 16-nation Southern African Development Community, told South Africa’s public broadcaster.
The Swaziland Democratic Nurses Union said in a statement that nurses and other workers who had converged on a public park in Mbabane, “were met with unprecedented show of force by the police and the army.”
“They were brutally dispersed and scattered all over the capital. As they were running, they were shot with live ammunition.”
The 30 injured were among more than 80 reported hurt on Wednesday in pro-democracy protests that have flared nationwide.
Radebe said the kingdom’s “issues are very complex,” and the team was “going there with an open mind, ensuring that we hear all views, so that at the end of the day the people of Eswatini... come up with a lasting solution.”
The latest flare-up in demonstrations has run for more than two weeks, spearheaded by students, civil servants and transport workers.
King Mswati III is Africa’s last absolute monarch, who enjoys flaunting his wealth and showering his 15 wives with lavish gifts.
Yet he rules over one of the poorest countries in the world, where nearly two-thirds of the population lives in poverty and a quarter of adults have HIV.

In a statement, the Communist Party of Swaziland said the situation at the largest government hospital in Mbabane on Wednesday resembled a “war zone.”
Hospital floors were “drenched in blood,” said the party, adding that police “invaded the hospital, shooting even nurses as they attended to the injured, worsening the situation.”
The nurse’s union said security forces kept shooting at nurses into the evening, even as they were traveling to work night shifts at hospitals.
“Clearly these blood-thirsty imbeciles, brood of vipers are hell-bent to kill nurses and the nation in defense of an ailing government,” the union said, calling on members not to treat any injured soldiers or police.
Five high-school students arrested during protests were arraigned on terrorism charges on Thursday for their role in the democracy push. Prosecutors accused them of burning down a police post.
At least 30 people have died since June in some of the worst unrest in the southern African country’s history.

Biden says US would come to Taiwan’s defense if attacked

BALTIMORE, Maryland: US President Joe Biden said on Thursday the United States would come to Taiwan’s defense and had a commitment to defend the island China claims as its own territory.
“Yes, we have a commitment to do that,” Biden said at a CNN town hall when asked if the United States would come to Taiwan’s defense.
Biden said people should not worry about Washington’s military strength because “China, Russia and the rest of the world knows we’re the most powerful military in the history of the world,“
“What you do have to worry about is whether or not they’re going to engage in activities that would put them in a position where they may make a serious mistake,” Biden said.
Military tensions between Taiwan and China are at their worst in more than 40 years, Taiwan’s Defense Minister Chiu Kuo-cheng said this month, adding that China will be capable of mounting a “full-scale” invasion by 2025.
China claims Taiwan as its own territory, which should be taken by force if necessary. Taiwan says it is an independent country and will defend its freedoms and democracy.


Governments turn tables on ransomware gang REvil by pushing it offline

Governments turn tables on ransomware gang REvil by pushing it offline

Governments turn tables on ransomware gang REvil by pushing it offline

Governments turn tables on ransomware gang REvil by pushing it offline
  • Law enforcement and intelligence cyber specialists were able to hack REvil's computer network infrastructure, obtaining control of at least some of their servers
  • One person familiar with the events said that a foreign partner of the US government carried out the hacking operation that penetrated REvil's computer architecture

The ransomware group REvil was itself hacked and forced offline this week by a multi-country operation, according to three private sector cyber experts working with the United States and one former official.
Former partners and associates of the Russian-led criminal gang were responsible for a May cyberattack on the Colonial Pipeline that led to widespread gas shortages on the US East Coast. REvil's direct victims include top meatpacker JBS. The crime group's "Happy Blog” website, which had been used to leak victim data and extort companies, is no longer available.
Officials said the Colonial attack used encryption software called DarkSide, which was developed by REvil associates.
VMWare head of cybersecurity strategy Tom Kellermann said law enforcement and intelligence personnel stopped the group from victimizing additional companies.
"The FBI, in conjunction with Cyber Command, the Secret Service and like-minded countries, have truly engaged in significant disruptive actions against these groups,” said Kellermann, an adviser to the US Secret Service on cybercrime investigations. “REvil was top of the list.”
A leadership figure known as "0_neday," who had helped restart the group's operations after an earlier shutdown, said REvil's servers had been hacked by an unnamed party.
"The server was compromised, and they were looking for me," 0_neday wrote on a cybercrime forum last weekend and first spotted by security firm Recorded Future. "Good luck, everyone; I'm off."
US government attempts to stop REvil, one of the worst of dozens of ransomware gangs that work with hackers to penetrate and paralyze companies around the world, accelerated after the group compromised US software management company Kaseya in July. 
That breach opened access to hundreds of Kaseya's customers all at once, leading to numerous emergency cyber incident response calls.

Decryption key
Following the attack on Kaseya, the FBI obtained a universal decryption key that allowed those infected via Kaseya to recover their files without paying a ransom.
But law enforcement officials initially withheld the key for weeks as it quietly pursued REvil's staff, the FBI later acknowledged. 
According to three people familiar with the matter, law enforcement and intelligence cyber specialists were able to hack REvil's computer network infrastructure, obtaining control of at least some of their servers.
After websites that the hacker group used to conduct business went offline in July, the main spokesman for the group, who calls himself "Unknown," vanished from the internet.
When gang member 0_neday and others restored those websites from a backup last month, he unknowingly restarted some internal systems that were already controlled by law enforcement.
“The REvil ransomware gang restored the infrastructure from the backups under the assumption that they had not been compromised,” said Oleg Skulkin, deputy head of the forensics lab at the Russian-led security company Group-IB. “Ironically, the gang's own favorite tactic of compromising the backups was turned against them.”
Reliable backups are one of the most important defenses against ransomware attacks, but they must be kept unconnected from the main networks or they too can be encrypted by extortionists such as REvil.
A spokesperson for the White House National Security Council declined to comment on the operation specifically.
"Broadly speaking, we are undertaking a whole of government ransomware effort, including disruption of ransomware infrastructure and actors, working with the private sector to modernize our defenses, and building an international coalition to hold countries who harbor ransom actors accountable," the person said.
The FBI declined to comment.
One person familiar with the events said that a foreign partner of the US government carried out the hacking operation that penetrated REvil's computer architecture. A former US official, who spoke on condition of anonymity, said the operation is still active.
The success stems from a determination by US Deputy Attorney General Lisa Monaco that ransomware attacks on critical infrastructure should be treated as a national security issue akin to terrorism, Kellermann said.
In June, Principal Associate Deputy Attorney General John Carlin told Reuters the Justice Department was elevating investigations of ransomware attacks to a similar priority.
Such actions gave the Justice Department and other agencies a legal basis to get help from US intelligence agencies and the Department of Defense, Kellermann said.
"Before, you couldn't hack into these forums, and the military didn't want to have anything to do with it. Since then, the gloves have come off."
