"Apple’s newest MacBooks apparently suffer from an unexpected problem, a keyboard issue that’s not easy to fix. Affected models include 2015 or later MacBook and 2016 or later MacBook Pro models. These laptops are thinner than ever, and Apple redesigned the mechanism under each key so that it could manufacture butterfly keyboards with an even slimmer profile.
Incredibly, it turns out that simple particles of dust can render individual keys on these machines useless, and dislodging them to fix them isn’t as easy as it was on older MacBook models."

"Wi-Fi: it's a technology that most of use every day and it's now at serious risk of being hijacked.
Security researchers have discovered a flaw in the security protocol used by almost every modern Wi-Fi device, including computers, phones and routers, which puts them all at risk of attack, reported ZDNet on Monday.
A weakness in the WPA2 protocol, which is used to secure most wireless networks and devices, was discovered by computer security academic Mathy Vanhoef, and is being nicknamed "KRACK", short for Key Reinstallation Attack.
The bug ultimately could allow hackers to eavesdrop on network traffic -- bad news for anyone sending sensitive or private information over a Wi-Fi connection. These days, that's pretty much all of us, although this could hit businesses using wireless point-of-sale machines particularly hard.
Hackers would have to be within physical range of a vulnerable device to take advantage of the flaw, but could use it to decrypt network traffic, hijack connections and inject content into the traffic stream.
To do so would involve effectively impersonating a user who had already been granted access to the network so as to exploit a weakness in the secure four-way handshake that acts as its gatekeeper."

When North Korean hackers tried to steal $1 billion from the New York Federal Reserve last year, only a spelling error stopped them. They were digitally looting an account of the Bangladesh Central Bank, when bankers grew suspicious about a withdrawal request that had misspelled “foundation” as “fandation.”
Even so, Kim Jong-un’s minions still got away with $81 million in that heist.
Then only sheer luck enabled a 22-year-old British hacker to defuse the biggest North Korean cyberattack to date, a ransomware attack last May that failed to generate much cash but brought down hundreds of thousands of computers across dozens of countries — and briefly crippled Britain’s National Health Service.
Their track record is mixed, but North Korea’s army of more than 6,000 hackers is undeniably persistent, and undeniably improving, according to American and British security officials who have traced these attacks and others back to the North.
Amid all the attention on Pyongyang’s progress in developing a nuclear weapon capable of striking the continental United States, the North Koreans have also quietly developed a cyberprogram that is stealing hundreds of millions of dollars and proving capable of unleashing global havoc.
