Apple celebrates its 40th anniversary this week at the top of its game, as the Silicon Valley legend that sprang out of Steve Jobs' garage to reshape modern life with its trend-setting gadgets.

Jobs, the late tech-savvy marketing genius, and Steve Wozniak, who invented the Apple computer, helped revolutionize how people use technology, and formed what would become the world's largest corporation with an eye-popping $53 billion in annual profits.

A Portuguese branch of the Anonymous hacking collective says it has shut down about 20 Angolan government websites in retaliation for the jailing of 17 youth activists for plotting "rebellion."

Two Chinese men were responsible for moving $81 million stolen by hackers from Bangladesh's foreign reserves into Philippine casinos, an inquiry in Manila heard on Tuesday.

Following the heist, the millions stolen from the Bangladesh central bank's American accounts on February 5 were immediately sent via electronic transfer to a Philippine bank.

The FBI has unlocked the iPhone used by one of the San Bernardino terror attackers, officials said Monday, ending a heated legal standoff with Apple that had pitted US authorities against Silicon Valley.

Apple, backed by a broad coalition of technology giants like Google and Facebook, was fiercely opposed to assisting the U.S. government in unlocking the iPhone on grounds it would have wide-reaching implications on digital security and privacy.

South Korea's Samsung Tuesday announced the launch of its mobile payment service in China, where it is likely to struggle in an already crowded market that arch-rival Apple entered nearly six weeks ago.

The world's second largest economy is also the world's biggest smartphone market, and Samsung Pay has a powerful partner in China -- bank card provider UnionPay -- which has links to the central bank.

Yahoo Inc. has given prospective buyers until April 11 to present preliminary offers for some of its assets, the Wall Street Journal reported late Monday.

Facebook apologized on Sunday for a bug that sent a Safety Check notification to users around the world following a deadly suicide bombing in Pakistan.

Facebook users from Honolulu to Brussels and Cairo to Hong Kong were baffled by the notification, a feature that lets users signal to friends that they are safe following an event in their area like a terror attack or natural disaster.

Apple has said the U.S. government's potential ability to unlock a phone used by one of the San Bernardino killers means the company may not have to provide help in a similar case in New York.

The tech giant wrote a letter to a federal court in Brooklyn on Thursday, setting out its position after the government said it may have found a way to crack the shooter's iPhone without Apple's help.

Hackers are stepping up efforts to turn their exploits into cold cash, locking a user's data unless a ransom is paid, a report found Tuesday.

In the fourth quarter of 2015, so-called ransomware increased 26 percent quarter-over-quarter, according to Intel Security.

The U.S. government has been adamant for weeks: FBI investigators need to unlock an encrypted iPhone used by one of the San Bernardino attackers, and Apple Inc. was the only one that could do it.

In a stunning reversal on Monday, federal prosecutors asked a judge to halt a much-anticipated hearing on their efforts to force Apple to unlock the phone. The FBI may have found another way, and Apple's cooperation may no longer be needed, according to court papers filed late Monday, less than 24 hours before Tuesday's hearing.
