Security Upgraded For NetBSD-amd64 with Kernel ASLR Support (netbsd.org) 44

24 years after its release, NetBSD is getting a security upgrade -- specifically, Address Space Layout Randomization (ASLR). An anonymous reader writes: Support for Kernel ASLR was added on NetBSD-amd64 a few weeks ago. KASLR basically randomizes the address of the kernel, and makes it harder to exploit several classes of vulnerabilities [including privilege escalations and remote code execution]. It is still a work-in-progress, but it's already fully functional, and can be used following the instructions on this post from the NetBSD blog. It will be available starting from NetBSD 9, but may be backported to NetBSD 8 once it is stabilized.
NetBSD says they're the first BSD system to support ASLR.

With Rising Database Breaches, Two-Factor Authentication Also At Risk (hackaday.com) 73

Two-factor authentication "protects from an attacker listening in right now," writes Slashdot reader szczys, "but in many case a database breach will negate the protections of two-factor." Hackaday reports: To fake an app-based 2FA query, someone has to know your TOTP password. That's all, and that's relatively easy. And in the event that the TOTP-key database gets compromised, the bad hackers will know everyone's TOTP keys.

How did this come to pass? In the old days, there was a physical dongle made by RSA that generated pseudorandom numbers in hardware. The secret key was stored in the dongle's flash memory, and the device was shipped with it installed. This was pretty plausibly "something you had" even though it was based on a secret number embedded in silicon. (More like "something you don't know?") The app authenticators are doing something very similar, even though it's all on your computer and the secret is stored somewhere on your hard drive or in your cell phone. The ease of finding this secret pushes it across the plausibility border into "something I know", at least for me.
The original submission calls two-factor authentication "an enhancement to password security, but good password practices are far and away still the most important of security protocols." (Meaning complex and frequently-changed passwords.)

A 14-Year-Old Asks: When Should I Get a VPN? 162

"One of my students sent me this letter," writes Slashdot reader Hasaf. "I have a good idea how I will answer, but I wanted to put it before the Slashdot community." The letter reads: Right now I am 14 years old, I was wondering when I should get a VPN... I was thinking about getting the yearly deal. But right now I really have no need for a VPN at the moment. I was thinking of getting a VPN when I'm in 11th grade or maybe in college. What do you think?
Of course, the larger question is what factors go into deciding whether your need to be using a VPN. So leave your best answers in the comments. When should you get your first VPN?

Microsoft Chastises Google Over Chrome Security (pcmag.com) 102

An anonymous reader quotes PCMag: In a Wednesday blog post, Redmond examined Google's browser security and took the opportunity to throw some shade at Chrome's security philosophy, while also touting the benefits of its own Edge browser. The post, written by Microsoft security team member Jordan Rabet, noted that Google's Chrome browser uses "sandboxing" and isolation techniques designed to contain any malicious code. Nevertheless, Microsoft still managed to find a security hole in Chrome that could be used to execute malicious code on the browser.

The bug involved a Javascript engine in Chrome. Microsoft notified Google about the problem, which was patched last month. The company even received a $7,500 reward for finding the flaw. However, Microsoft made sure to point out that its own Edge browser was protected from the same kind of security threat. It also criticized Google for the way it handled the patching process. Prior to the patch's official rollout, the source code for the fix was made public on GitHub, a software collaboration site that hosts computer code. That meant attentive hackers could have learned about the vulnerability before the patch was pushed out to customers, Microsoft claimed. "In this specific case, the stable channel of Chrome remained vulnerable for nearly a month," the blog post said. "That is more than enough time for an attacker to exploit it."

In the past Google has also disclosed vulnerabilities found in Microsoft products -- including Edge.

US Government Warns Of 'Ongoing' Hacks Targeting Nuclear and Power Industries (reuters.com) 91

An anonymous reader quotes Reuters: The U.S government issued a rare public warning that sophisticated hackers are targeting energy and industrial firms, the latest sign that cyber attacks present an increasing threat to the power industry and other public infrastructure. The Department of Homeland Security and Federal Bureau of Investigation warned in a report distributed by email late on Friday that the nuclear, energy, aviation, water and critical manufacturing industries have been targeted along with government entities in attacks dating back to at least May. The agencies warned that hackers had succeeded in compromising some targeted networks, but did not identify specific victims or describe any cases of sabotage. The objective of the attackers is to compromise organizational networks with malicious emails and tainted websites to obtain credentials for accessing computer networks of their targets, the report said.
According to the report, the Department of Homeland Security "has confidence that this campaign is still ongoing and threat actors are actively pursuing their objectives over a long-term campaign."

2 Million IoT Devices Enslaved By Fast-Growing BotNet (bleepingcomputer.com) 67

An anonymous reader writes: Since mid-September, a new IoT botnet has grown to massive proportions. Codenamed IoT_reaper, researchers estimate its current size at nearly two million infected devices. According to researchers, the botnet is mainly made up of IP-based security cameras, routers, network-attached storage (NAS) devices, network video recorders (NVRs), and digital video recorders (DVRs), primarily from vendors such as Netgear, D-Link, Linksys, GoAhead, JAWS, Vacron, AVTECH, MicroTik, TP-Link, and Synology.

The botnet reuses some Mirai source code, but it's unique in its own right. Unlike Mirai, which relied on scanning for devices with weak or default passwords, this botnet was put together using exploits for unpatched vulnerabilities. The botnet's author is still struggling to control his botnet, as researchers spotted over two million infected devices sitting in the botnet's C&C servers' queue, waiting to be processed. As of now, the botnet has not been used in live DDoS attacks, but the capability is in there.

Today is the one-year anniversary of the Dyn DDoS attack, the article points out, adding that "This week both the FBI and Europol warned about the dangers of leaving Internet of Things devices exposed online."

Google Offers $1,000 Bounties For Hacking Dropbox, Tinder, Snapchat, and Others (mashable.com) 35

An anonymous reader quotes Mashable: Google, in collaboration with bug bounty platform HackerOne, has launched the Google Play Security Reward Program, which promises $1,000 to anyone who can identify security vulnerabilities in participating Google Play apps. Thirteen apps are currently participating, including Tinder, Duolingo, Dropbox, Snapchat, and Headspace... If you find a security vulnerability in one of the participating apps, you can report that vulnerability to the developer, and work with them to fix it. When the problem has been resolved, the Android Security team will pay you $1,000 as a reward, on top of any reward you get from the app developer. Google will be collecting data on the vulnerabilities and sharing it (anonymized) with other developers who may be exposed to the same problems. For HackerOne, it's about attracting more and better participants in bounty programs.

Why Are We Still Using Passwords? (securityledger.com) 179

Here's some surprising news from the Akamia Edge conference. chicksdaddy writes: [E]xecutives at some of the U.S.'s leading corporations agreed that the much maligned password won't be abandoned any time soon, even as data breaches and follow-on attacks make passwords more susceptible than ever to abuse, the Security Ledger reports. "We reached the end of needing passwords maybe seven years ago, but we still use them," said Steve Winterfeld, Director of Cybersecurity, at clothing retailer Nordstrom. "They're still the primary layer of defense."

"It's hard to kill them," noted Shalini Mayor, who is a Senior Director at Visa Inc. "The question is what to replace them with." This, even though the cost of using passwords is high and getting higher, as sophisticated attacks attempt to compromise legitimate accounts using so-called "credential stuffing" techniques, which use automated password guessing attacks against web-based applications... Stronger and more reliable alternatives to passwords already exist, but the obstacles to using them are often prohibitive. Shalani Mayor said Visa is "looking at" biometric technologies like Apple's TouchID as a tool for making payments securely. Such technologies -- from fingerprint scans to facial and retinal scans -- promise more secure and reliable factors than alphanumeric passwords, the executives agreed. But customers often resist the technologies or find them error prone or too difficult to use.

Body Camera Study Shows No Effect On Police Use of Force Or Citizen Complaints (npr.org) 133

An anonymous reader quotes a report from NPR: Having police officers wear little cameras seems to have no discernible impact on citizen complaints or officers' use of force, at least in the nation's capital. That's the conclusion of a study performed as Washington, D.C., rolled out its huge camera program. The city has one of the largest forces in the country, with some 2,600 officers now wearing cameras on their collars or shirts. In the wake of high-profile shootings, many police departments have been rapidly adopting body-worn cameras, despite a dearth of solid research on how the technology can change policing. "We need science, rather than our speculations about it, to try to answer and understand what impacts the cameras are having," says David Yokum, director of the Lab @ DC. His group worked with local police officials to make sure that cameras were handed out in a way that let the researchers carefully compare officers who were randomly assigned to get cameras with those who were not. The study ran from June 2015 to last December. It's to be expected that these cameras might have little impact on the behavior of police officers in Washington, D.C., he says, because this particular force went through about a decade of federal oversight to help improve the department.

Google Says 64 Percent of Chrome Traffic On Android Now Protected With HTTPS, 75 Percent On Mac, 66 Percent On Windows (techcrunch.com) 90

An anonymous reader quotes a report from TechCrunch: Google's push to make the web more secure by flagging sites using insecure HTTP connections appears to be working. The company announced today that 64 percent of Chrome traffic on Android is now protected, up 42 percent from a year ago. In addition, over 75 percent of Chrome traffic on both ChromeOS and Mac is now protected, up from 60 percent on Mac and 67 percent on ChromeOS a year ago. Windows traffic is up to 66 percent from 51 percent. Google also notes that 71 of the top 100 websites now use HTTPS by default, up from 37 percent a year ago. In the U.S., HTTPS usage in Chrome is up from 59 percent to 73 percent. Combined, these metrics paint a picture of fairly rapid progress in the switchover to HTTPS. This is something that Google has been heavily pushing by flagging and pressuring sites that hadn't yet adopted HTTPS.

Student Expelled After Using Hardware Keylogger to Hack School, Change Grades (bleepingcomputer.com) 135

Catalin Cimpanu, writing for BleepingComputer: Kansas University (KU) officials have expelled a student for installing a hardware keylogger and using the data acquired from the device to hack into the school's grading system and chang his grades. KU did not release the student's name to the public, but they said the keystroke logging device had been installed on one of the computers in its lecture halls. The student used data collected from the device to change F grades into A grades. Professors said the incident would not have been noticed if the student didn't get greedy about modifications. The hardware device the student used was a run-of-the-mill hardware keylogger that anyone can buy on Amazon or eBay for prices as low as $20. Speaking to local media, various KU professors said they hope not to see any copycats in the near future.

MasterCard Has Finally Realized That Signatures Are Obsolete and Stupid (fastcompany.com) 331

An anonymous reader shares a report: For years, credit card companies have relied on an illegible squiggly line as the frontline of defense against credit card fraud. Customers are forced to use a pen (how retro!) to scrawl their signature on bills at restaurants and sign digitally at cash registers -- as if somehow in the age of chips, PINs, biometrics, and online fraud alerts, a line on a page is still a great tool against fraud prevention. Personally, I have been known to sign on the dotted line with a doodle of a piece of tofu and no one has ever stopped me, because signatures mean very little in this digital age. Companies are finally seeing the light. Starting in April 2018, MasterCard cardholders will no longer be required to sign their name when they purchase something using their debit or credit cards. The company has been moving away from requiring signatures for a few years now, with only about 80% of purchases (typically over a certain dollar amount) requiring a signature these days. MasterCard did some digging, though, and per its press release, realized that most of their customers "believe it would be easier to pay and that checkout lines would move faster if they didn't need to sign when making a purchase."

Facebook Security Chief Says Its Corporate Network Is Run 'Like a College Campus' (zdnet.com) 83

An anonymous reader quotes a report from ZDNet: Facebook's security chief has told employees that the social media giant needs to improve its internal security practices to be more akin to a defense contractor, according to a leaked recording obtained by ZDNet. Alex Stamos made the comments to employees at a late-July internal meeting where he argued that the company had not done enough to respond to the growing threats that the company faces, citing both technical challenges and cultural issues at the company. "The threats that we are facing have increased significantly and the quality of the adversaries that we are facing," he said. "Both technically and from a cultural perspective I don't feel like we have caught up with our responsibility. The way that I explain to [management] is that we have the threat profile of a Northrop Grumman or a Raytheon or another defense contractor, but we run our corporate network, for example, like a college campus, almost," he said.

Apple Watch's LTE Suspended In China Possibly Due To Government Security Concerns (appleinsider.com) 18

The Apple Watch Series 3's best new feature has been mysteriously blocked in China. According to a report from The Wall Street Journal, China has cut off the Apple Watch's LTE connectivity on Sept. 28 after brief availability from China Unicom. Industry analysts claim that the suspension is probably from governmental concerns about not being able to track and confirm users of the device. AppleInsider reports: Apple issued a brief statement confirming the situation, and referring customers to China Unicom. Neither China Unicom, nor Chinese regulators have made any statement on the matter. The issue may stem from the eSIM in the Apple Watch. Devices like the iPhone have state-owned telecom company-issued SIM cards -- and the eSIM is embedded in the device by Apple. "The eSIM (system) isn't mature enough yet in China," one analyst said. "The government still needs to figure out how they can control the eSIM." The LTE version of the Apple Watch had only a trial certificate to operate on the Chinese LTE network. An analyst who asked not to be identified expects that Ministry of Industry and Information Technology may take months to figure out how the government will deal with the eSIM, and issue a formal certificate for operation.

Canada's 'Super Secret Spy Agency' Is Releasing a Malware-Fighting Tool To the Public (www.cbc.ca) 66

Matthew Braga, reporting for CBC News: Canada's electronic spy agency says it is taking the "unprecedented step" of releasing one of its own cyber defence tools to the public, in a bid to help companies and organizations better defend their computers and networks against malicious threats. The Communications Security Establishment (CSE) rarely goes into detail about its activities -- both offensive and defensive -- and much of what is known about the agency's activities have come from leaked documents obtained by U.S. National Security Agency whistleblower Edward Snowden and published in recent years. But as of late, CSE has acknowledged it needs to do a better job of explaining to Canadians exactly what it does. Today, it is pulling back the curtain on an open-source malware analysis tool called Assemblyline that CSE says is used to protect the Canadian government's sprawling infrastructure each day. "It's a tool that helps our analysts know what to look at, because it's overwhelming for the number of people we have to be able to protect things," Scott Jones, who heads the agency's IT security efforts, said in an interview with CBC News. On the one hand, open sourcing Assemblyline's code is a savvy act of public relations, and Jones readily admits the agency is trying to shed its "super secret spy agency" reputation in the interest of greater transparency.

Targeted Fuzzing Is Improving Linux Security, Linus Torvalds Says (iu.edu) 62

On the sidelines of announcing the fifth release candidate for the Linux kernel version 4.14, Linus Torvalds said fuzzing, which involves stress testing a system by generating random code to induce errors, is helping the community find and fix a range of security vulnerabilities. He wrote: The other thing perhaps worth mentioning is how much random fuzzing people are doing, and it's finding things. We've always done fuzzing (who remembers the old "crashme" program that just generated random code and jumped to it? We used to do that quite actively very early on), but people have been doing some nice targeted fuzzing of driver subsystems etc, and there's been various fixes (not just this last week either) coming out of those efforts. Very nice to see.

Google Engineers Explore Ways To Stop In-Browser Cryptocurrency Miners in Chrome (bleepingcomputer.com) 185

An anonymous reader writes: Google Chrome engineers are considering adding a special browser permission that will thwart the rising trend of in-browser cryptocurrency miners. Discussions on the topic of in-browser miners have been going on the Chromium project's bug tracker since mid-September when Coinhive, the first such service, launched. "Here's my current thinking," Ojan Vafai, a Chrome engineering working on the Chromium project, wrote in one of the recent bug reports. "If a site is using more than XX% CPU for more than YY seconds, then we put the page into 'battery saver mode' where we aggressively throttle tasks and show a toast [notification popup] allowing the user to opt-out of battery saver mode. When a battery saver mode tab is backgrounded, we stop running tasks entirely. I think we'll want measurement to figure out what values to use for XX and YY, but we can start with really egregious things like 100% and 60 seconds. I'm effectively suggesting we add a permission here, but it would have unusual triggering conditions [...]. It only triggers when the page is doing a likely bad thing."

An earlier suggestion had Google create a blacklist and block the mining code at the browser level. That suggestion was shut down as being too impractical and something better left to extensions.

EU: No Encryption Backdoors But, Let's Help Each Other Crack That Crypto (theregister.co.uk) 81

The European Commission has proposed that member states help each other break into encrypted devices by sharing expertise around the bloc. From a report: In an attempt to tackle the rise of citizens using encryption and its effects on solving crimes, the commission decided to sidestep the well-worn, and well-ridiculed, path of demanding decryption backdoors in the stuff we all use. Instead, the plans set out in its antiterrorism measures on Wednesday take a more collegiate approach -- by offering member states more support when they actually get their hands on an encrypted device. "The commission's position is very clear -- we are not in favour of so-called backdoors, the utilisation of systemic vulnerabilities, because it weakens the overall security of our cyberspace, which we rely upon," security commissioner Julian King told a press briefing. "We're trying to move beyond a sometimes sterile debate between backdoors or no backdoors, and address some of the concrete law enforcement challenges. For instance, when [a member state] gets a device, how do they get information that might be encrypted on the device." [...] Share the wealth. "Some member states are more equipped technically to do that [extract information from a seized device] than others," King said. "We want to make sure no member state is at a disadvantage, by sharing the tech expertise among the member states and reinforcing the support that Europol can offer."

Dodging Russian Spies, Customers Are Ripping Out Kaspersky (thedailybeast.com) 354

From a report: Multiple U.S. security consultants and other industry sources tell The Daily Beast customers are dropping their use of Kaspersky software all together, particularly in the financial sector, likely concerned that Russian spies can rummage through their files. Some security companies are being told to only provide U.S. products. And former Kaspersky employees describe the firm as reeling, with department closures and anticipation that researchers will jump ship soon. "We are under great pressure to only use American products no matter the technical or performance consequences," said a source in a cybersecurity firm which uses Kaspersky's anti-virus engine in its own services. The Daily Beast granted anonymity to some of the industry sources to discuss internal deliberations, as well as the former Kaspersky employees to talk candidly about recent events.

Ask Slashdot: What Are Ways To Get Companies To Actually Focus On Security? 158

New submitter ctilsie242 writes: Many years ago, it was said that we would have a "cyber 9/11," a security event so drastic that it fundamentally would change how companies and people thought about security. However, this has not happened yet (mainly because the bad guys know that this would get organizations to shut their barn doors, stopping the gravy train.) With the perception that security has no financial returns, coupled with the opinion that "nobody can stop the hackers, so why even bother," what can actually be done to get businesses to have an actual focus on security. The only "security" I see is mainly protection from "jailbreaking," so legal owners of a product can't use or upgrade their devices. True security from other attack vectors are all but ignored. In fact, I have seen some development environments where someone doing anything about security would likely get the developer fired because it took time away from coding features dictated by marketing. I've seen environments where all code ran as root or System just because if the developers gave thought to any permission model at all, they would be tossed, and replaced by other developers who didn't care to "waste" their time on stuff like that.

One idea would be something similar to Underwriters Labs, except would grade products, perhaps with expanded standards above the "pass/fail" mark, such as Europe's "Sold Secure," or the "insurance lock" certification (which means that a security device is good enough for insurance companies to insure stuff secured by it.) There are always calls for regulation, but with regulatory capture being at a high point, and previous regulations having few teeth, this may not be a real solution in the U.S. Is our main hope the new data privacy laws being enacted in Europe, China, and Russia, which actually have heavy fines as well as criminal prosecutions (i.e. execs going to jail)? This especially applies to IoT devices where it is in their financial interest to make un-upgradable devices, forcing people to toss their 1.0 lightbulbs and buy 1.0.1 lightbulbs to fix a security issue, as opposed to making them secure in the first place, or having an upgrade mechanism. Is there something that can actually be done about the general disinterest by companies to make secure products, or is this just the way life is now?
