Explainer: How chip flaws Spectre,
Meltdown work and what´s next

Reuters, by Paresh Dave

Original Article

Posted By:LittleHoodedMonk, 1/12/2018 2:31:08 AM

Las Vegas - Smartphones, PCs and servers across the world have received software updates in recent days to plug security gaps on computer chips that cyber security researchers have described as the most serious threat in years. Researchers identified the problem last year, shared details with chip manufacturers last summer, and then made a public announcement Jan. 3. What is the problem? The vulnerabilities, known as Meltdown and Spectre, can allow passwords and other sensitive data on chips to be read. The flaws result from the way computers try to guess what users are likely to do next, a process called speculative

Comments:
I probably shouldn´t be asking, but someone high up in in our government should. That is, what about our military systems and satellites that probably use these chips? Bueller? A much more detailed analysis & updates:

From what I have learned these attacks depend on accurate timing of instructions issued after an if statement (a branch instruction).
During program operation, the computer learns the most likely branch to take and will speculatively execute that branch every time the if statement is encountered. If the the result of the if statement is different, the results of the speculation are discarded, except! what is in the cache.

If the speculated instructions reference protected memory the contents will be left in the cache and clever code can determine the contents by timing instructions that reference data which might be in the cache.
The details are very geeky.

If the protected memory was referenced by non speculated instructions a protection violation would result with no data in the cache.

There are two basic problems here. 1. the cancelling of the speculative instructions does not clear the affected cache, 2. the speculative execution does not honor the memory protection status.

The website attack can be thwarted by fuzzing the clock values available to javascript. This is easy and Mozilla has sent updates to do that.

The kernel problem can be fixed by altering the way the operating system maps virtual memory. The fix is to remove a shortcut in the kernel which will have some impact on performance.

Those running old kernels will likely not get updates to fix this. There is a rumor that MacOS 10.13 already has the kernel fix.

I hope this helps a little bit. There are published papers that go into great detail.

I have always advised against storing passwords, account numbers and other sensitive data on any device. The convenience does not outweigh the consequences.

We do not trust the media because they are idiots!

"can allow passwords and other sensitive data on chips to be read"

The data does not need to be on the chip.

"computers try to guess what users are likely to do next, a process called speculative execution"

The computer is trying to predict what *it* should do next, not what the *user* is going to do next.

#2 gets it right.

A former Democratic congressman from Chicago, heading to prison for the third time, says he has “given up on America” and plans to move to Africa after he serves his latest sentence. At his sentencing Thursday, Mel Reynolds, 66, got six months in prison for failing to file tax returns on more than $400,000 he received for consulting work. He also received a scolding from federal Judge Robert Gettleman, who told the Harvard graduate he could recall thinking to himself in the early 1990s that Reynolds had tremendous promise. “It's a tragedy that you squandered the opportunities you had and the type of person you could have become,"

Trump announces the capture of the five

Daily Mail [UK], by David Martosko, Rory Tingle    Original Article

A jubilant President Trump tweeted on Thursday to announce that five of the ´Most Wanted leaders of ISIS´ have been captured after they were lured from Syria to Iraq with fake Telegram messages. Iraqi officials used the cell phone of already captured ISIS lieutenant Ismail al-Eithawi to send instructions via the app for the four other leaders to come to Iraq, where they were seized. The encrypted app was officially named by ISIS as one of its favored mobile messaging services in 2015 and has been regularly used by the terror group for private communication and to spread propaganda.

Iran strikes prove Trump’s
nuke-deal move is already a win
New York Post, by Editorial    Original Article

President Trump’s decision to scrap the Iran nuke deal had a lot to do with Tehran’s decision to fire missiles at Israel late Wednesday. First, the Iranians likely timed the attack to make it seem that the president had instantly made things worse in the region. That also explains why Iran’s Houthi proxies in Yemen shot missiles into Saudi Arabia hours after Trump’s nuke-deal news. Second, Iran’s power in Syria and Yemen is itself in good part the result of Team Obama’s policies, including the nuke deal — which left Washington with few ways to respond to Tehran’s non­nuclear outrages while freeing up billions in cash to fund Iranian

Boston - Some immigrants living in the country illegally and accused of crimes sit in legal limbo, caught in a tug of a war between local prosecutors and federal immigration authorities who won´t let them appear in court because they fear being denied the opportunity to deport them. (Snip) Under President Trump, the agency is specifically targeting suspects not yet found guilty, a departure from the Obama administration, which focused primarily on those convicted, attorneys say. Advocates argue ICE has also sometimes used criminal allegations against immigrants in their deportation efforts without letting them answer the charges.

Depok, Indonesia — A day after Islamic State followers seized part of a high-security terrorist detention center and killed five guards, the country was left on Thursday with no shortage of questions to ponder. (Snip) Located in the sleepy West Java town of Depok, south of the Indonesian capital, Jakarta, the detention center is in a sprawling, heavily guarded compound of the local headquarters of the Mobile Brigade Corps, a paramilitary unit of the Indonesian National Police, and it was guarded by elite counterterrorism officers.

Jerusalem - The Israeli military on Thursday said it attacked “dozens” of Iranian targets in neighboring Syria in response to an Iranian rocket barrage on Israeli positions in the Golan Heights, in the most serious military confrontation between the two bitter enemies to date. Israel said the targets included weapons storage, logistics sites and intelligence centers used by elite Iranian forces in Syria. It also said it destroyed several Syrian air-defense systems after coming under heavy fire. It said none of its warplanes was hit. The blistering Israeli assault was by far the most intensive Israeli action in neighboring Syria since the civil war

Jerusalem - Russia is unlikely to try to limit Israel’s military actions in Syria, Israeli Prime Minister Benjamin Netanyahu said on Wednesday after meeting Russian President Vladimir Putin. (Snip) After the talks with Putin, Netanyahu sounded upbeat. “In previous meetings, given statements that were putatively attributed to - or were made by - the Russian side, it was meant to have limited our freedom of action or harm other interests and that didn’t happen, and I have no basis to think that this time will be different,” he told reporters in a phone briefing. There was no immediate comment from the Kremlin.

The allegation that New York Attorney General and #MeToo champion Eric Schneiderman assaulted several women has New York and the Democratic Party reeling. The stories are horrific and, in this time of #MeToo, disgustingly familiar. Within a few hours of the Jane Mayer and Ronan Farrow New Yorker Magazine allegations going public, Mr. Schneiderman denied the accusations and then tried to explain himself by saying he engaged in consensual “role playing” with sex partners. An unbelievable excuse for many, and directly refuted in the story itself, that evening he announced his resignation, effective the end of Tuesday.

Noam Chomsky may not be a household name in most circles, but the philosopher and linguist has a reputation in academic and political circles for his outspoken radical left worldview. In a recent 90-minute speech at St. Olaf College (no word if Rose Nylund is an alumna), Chomsky declared that he knows the biggest threat to the world. And boy, is it a doozy! So, is the truest threat to the world North Korea? Is it Iran or ISIS? How about Russia or China? Nope. According to Chomsky, nuclear war and climate change are pretty scary, but the big threats

Two unnamed sources told The Hill that Sadler took issue with McCain´s criticism of President Donald Trump´s CIA nominee, Gina Haspel, allegedly dismissing the ailing McCain, saying "he´s dying anyway." McCain on Wednesday said that Haspel is unfit to run the CIA because she would not say definitively that torture is immoral. That issue is one of several that have made Haspel´s journey toward Senate confirmation an uphill battle.
