U.S. Navy bans TikTok from government-issued mobile devices

Earlier this week the United States Navy banned the social media app TikTok from government-issued mobile devices, saying the popular short video app represented a “cybersecurity threat.” A bulletin issued by the Navy on Tuesday showed up on a Facebook page serving military members, saying users of government-issued mobile devices who had TikTok and did not remove the app would be blocked from the Navy Marine Corps Intranet. The Navy would not describe in detail what dangers the app presents, but Pentagon spokesman Lieutenant Colonel Uriah Orland said in a statement the order was part of an effort to “address existing and emerging threats.” TikTok did not return a request for comment. TikTok is hugely popular with U.S. teenagers but has come under scrutiny from U.S. regulators and lawmakers in recent months.

The U.S. government has opened a national security review of the app’s owner Beijing ByteDance Technology Co’s $1 billion acquisition of U.S. social media app Musical.ly, Reuters first reported last month. Last month, U.S army cadets were instructed not to use TikTok, after Senator Chuck Schumer raised security concerns about the army using TikTok in their recruiting. A Navy spokesman said Naval and Marine personnel who use government-issued smart devices are generally allowed to use popular commercial apps, including common social media apps, but from time to time specific programs that present security threats are banned. He would not give examples of apps that are allowed or those considered unsafe. The Pentagon’s Orland said the “Cyber Awareness Message” sent Dec. 16 “identifies the potential risk associated with using the TikTok app and directs appropriate action for employees to take in order to safeguard their personal information.”

Australia faces catastrophic fire conditions as temperatures soar to 40C

Temperatures above 40C and strong winds created “catastrophic” conditions on Saturday for firefighters battling more than 100 fires burning across New South Wales state, while in South Australia one person was found dead in a fire zone. Some roads outside Sydney were closed and authorities asked people to delay travel, at the start of what is normally a busy Christmas holiday period, warning of the unpredictability of the fires as winds of up to 70 kph (44 mph) were set to fan the flames. “Catastrophic fire conditions are as bad as it gets,” NSW Rural Fire Services Commissioner Shane Fitzsimmons told journalists. “They are the very worst of conditions. Given we have a landscape with so much active fire burning, you have a recipe for very serious concern and a very dangerous day.” Greater Sydney and two surrounding areas were rated as catastrophic for Saturday, and other areas were at extreme or very-high fire danger ratings. Close to 10,000 emergency personnel would be working across NSW on Saturday. The state’s Minister for Police and Emergency Services David Elliott described it as probably the largest emergency deployment ever seen in NSW. A southerly wind change is expected late on Saturday afternoon.

It is forecast to bring winds of up to 90 kph (56 mph), which Fitzsimmons said would initially worsen fire conditions before leading to a dramatic drop in temperatures. The death of two firefighters on Thursday night when their fire truck was struck by a falling tree as it traveled through the front line of a fire brought the wildfires death toll in New South Wales to eight since the start of October. Shortly after the two deaths were announced, Prime Minister Scott Morrison issued a statement saying he would return as soon as possible from a family holiday in Hawaii, a trip that had drawn sharp criticism as the wildfires crisis deepened. In South Australia, authorities said one person had been found dead, another was critically injured and 15 homes had been destroyed by a fire in the Adelaide Hills, just 40 kilometers (25 miles) east of the state capital of Adelaide. The death followed another fatality in South Australia on Friday, the result of a car crash in an area where an emergency fire warning was in place. Authorities said 23 firefighters suffered injuries on Friday as the parts of the state endured catastrophic fire conditions. In the state of Victoria, 15 blazes were burning out of control on Saturday morning, with an emergency warning placed on two in the state’s east. Australia has been fighting wildfires across a number of states for weeks, with blazes destroying more than 700 homes and nearly 3 million acres (1.2 million hectares) of bushland.
