The founder of Rendition Security believes his daughter "is more safe on a Chromebook than a Windows laptop," and he's not the only one. CNET's staff reporter argues that Google's push for simplicity, speed, and security "ended up playing off each other." mspohr shared this article: Heading to my first security conference last year, I expected to see a tricked-out laptop running on a virtual machine with a private network and security USB keys sticking out -- perhaps something out of a scene from "Mr. Robot." That's not what I got. Everywhere I went I'd see small groups of people carrying Chromebooks, and they'd tell me that when heading into unknown territory it was their travel device... "If you want prehardened security, then Chromebooks are it," said Kenneth White, director of the Open Crypto Audit Project. "Not because they're Google, but because Chrome OS was developed for years and it explicitly had web security as a core design principle...." Drewry and Liu focused on four key features for the Chromebook that have been available ever since the first iteration in 2010: sandboxing, verified boots, power washing and quick updates. These provided security features that made it much harder for malware to pass through, while providing a quick fix-it button if it ever did.

That's not to say Chrome OS is impervious to malware. Cybercriminals have figured out loopholes through Chrome's extensions, like when 37,000 devices were hit by the fake version of AdBlock Plus. Malicious Android apps have also been able to sneak through the Play Store. But Chrome OS users mostly avoided massive cyberattack campaigns like getting locked up with ransomware or hijacked to become part of a botnet. Major security flaws for Chrome OS, like ones that would give an attacker complete control, are so rare that Google offers rewards up to $200,000 to anyone who can hack the system.
The article argues that "Fewer software choices mean limited options for hackers. Those are some of the benefits that have led security researchers to warm up to the laptops...

"Chrome OS takes an approach to security that's similar to the one Apple takes with iOS and its closed ecosystem."

A 1.35 terabit-per-second DDoS attack hit GitHub all at once last Wednesday. "It was the most powerful distributed denial of service attack recorded to date -- and it used an increasingly popular DDoS method, no botnet required," reports Wired. From the report: GitHub briefly struggled with intermittent outages as a digital system assessed the situation. Within 10 minutes it had automatically called for help from its DDoS mitigation service, Akamai Prolexic. Prolexic took over as an intermediary, routing all the traffic coming into and out of GitHub, and sent the data through its scrubbing centers to weed out and block malicious packets. After eight minutes, attackers relented and the assault dropped off. "We modeled our capacity based on fives times the biggest attack that the internet has ever seen," Josh Shaul, vice president of web security at Akamai told WIRED hours after the GitHub attack ended. "So I would have been certain that we could handle 1.3 Tbps, but at the same time we never had a terabit and a half come in all at once. It's one thing to have the confidence. It's another thing to see it actually play out how you'd hope."

Akamai defended against the attack in a number of ways. In addition to Prolexic's general DDoS defense infrastructure, the firm had also recently implemented specific mitigations for a type of DDoS attack stemming from so-called memcached servers. These database caching systems work to speed networks and websites, but they aren't meant to be exposed on the public internet; anyone can query them, and they'll likewise respond to anyone. About 100,000 memcached servers, mostly owned by businesses and other institutions, currently sit exposed online with no authentication protection, meaning an attacker can access them, and send them a special command packet that the server will respond to with a much larger reply.

chicksdaddy brings this report from Security Ledger: The Security Innovation Center, with backing of powerful tech industry groups, is arguing that letting consumers fix their own devices will empower hackers. The group released a survey last week warning of possible privacy and security risks should consumers have the right to repair their own devices. It counts powerful electronics and software industry organizations like CompTIA, CTIA, TechNet and the Consumer Technology Association as members... In an interview with The Security Ledger, Josh Zecher, the Executive Director of The Security Innovation Center, acknowledged that Security Innovation Center's main purpose is to push back on efforts to pass right to repair laws in the states.

He said the group thinks such measures are dangerous, citing the "power of connected products and devices" and the fact that they are often connected to each other and to the Internet via wireless networks. Zecher said that allowing device owners or independent repair professionals to service smart home devices and connected appliances could expose consumer data to hackers or identity thieves... Asked whether Security Innovation Center was opposed to consumers having the right to repair devices they purchased and owned, Zecher said the group did oppose that right on the grounds of security, privacy and safety... "People say 'It's just my washing machine. Why can't I fix it on my own?' But we saw the Mirai botnet attack last year... Those kinds of products in the wrong hands can be used to do bad things."

Ian Barker, writing for BetaNews: While US government agencies are continuing to improve their security performance over time, the contractors they employ are failing to meet the same standards according to a new report. The study by security rankings specialist BitSight sampled over 1,200 federal contractors and finds that the security rating for federal agencies was 15 or more points higher than the mean of any contractor sector. It finds more than eight percent of healthcare and wellness contractors have disclosed a data breach since January 2016. Aerospace and defense firms have the next highest breach disclosure rate at 5.6 percent. While government has made a concerted effort to fight botnets in recent months, botnet infections are still prevalent among the government contractor base, particularly for healthcare and manufacturing contractors. The study also shows many contractors are not following best practices for network encryption and email security.

If you're thinking about buying gadgets from auction sites such as Ebay, you will want to consider the potential risks. From a report: When you're buying from a third-party seller, it's a lot more difficult to tell where products have come from, whether you're getting exactly what you think you're getting, and if anything has been done to the product since it was manufactured. "It is possible for internet-connected devices to be tampered with and resold on the web," Leigh-Anne Galloway, lead cybersecurity resilience analyst at the cybersecurity firm Positive Technologies, told Quartz. "It's similar to buying a secondhand cellphone without it being restored to factory settings." In fact, buying a second hand gadget can potentially expose the user to some pretty extreme scenarios. "Cameras and IoT devices can contain spyware and malware, which can cause a plethora of problems for the user," Galloway added. "These devices could possibly listen to you, watch your every step, communicate with and attack other devices connected to the same local network, such as PCs, laptops, and TVs." Galloway said devices could also be used to perform botnet attacks -- where an unsecured internet-connected device is accessed by another computer and used along with other breached devices to take down websites or internet services, as what happened with the Mirai botnet attack in 2016.

Three hackers responsible for creating the massive Mirai botnet that knocked large swathes of the internet offline last year have pleaded guilty. Brian Krebs reports: The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men (Editor's note: three men) first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called "Internet of Things" devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site). Entering guilty pleas for their roles in developing and using Mirai are 21-year-old Paras Jha from Fanwood, N.J. and Josiah White, 20, from Washington, Pennsylvania. Jha and White were co-founders of Protraf Solutions LLC, a company that specialized in mitigating large-scale DDoS attacks. Like firemen getting paid to put out the fires they started, Jha and White would target organizations with DDoS attacks and then either extort them for money to call off the attacks, or try to sell those companies services they claimed could uniquely help fend off the attacks. Editor's note: The story was updated to note that three men have pleaded guilty. -- not two as described in some reports.

Yes, U.S. Senator Chuck Schumer actually called them "Grinch bots." From the New York Post: The senator said as soon as a retailer puts a hard-to-get toy -- like Barbie's Dreamhouse or Nintendo game systems -- for sale on a website, a bot can snatch it up even before a kid's parents finish entering their credit card information... "Bots come in and buy up all the toys and then charge ludicrous prices amidst the holiday shopping bustle," the New York Democrat said on Sunday... For example, Schumer said, the popular Fingerlings -- a set of interactive baby monkey figurines that usually sell for around $15 -- are being snagged by the scalping software and resold on secondary websites for as much as $1,000 a pop...

In December 2016, Congress passed the Better Online Ticket Sales (BOTS) Act, which Schumer sponsored, to crack down on their use to buy concert tickets, but the measure doesn't apply to other consumer products. He wants that law expanded but knows that won't happen in time for this holiday season. In the meantime, Schumer wants the National Retail Federation and the Retail Industry Leaders Association to block the bots and lead the effort to stop them from buying toys at fair retail prices and then reselling them at outrageous markups.

Long-time Slashdot reader doom writes: Over a two year period, a third of the IPv4 address space have experienced some sort of DoS attack, though the researchers who've ascertained this suspect this is an underestimate. This is from a story at Science Daily reporting on a study recently presented in London at the Internet Measurement Conference.

"As might be expected, more than a quarter of the targeted addresses in the study came in the United States, the nation with the most internet addresses in the world. Japan, with the third most internet addresses, ranks anywhere from 14th to 25th for the number of DoS attacks, indicating a relatively safe nation for DoS attacks..."

The study itself states, "On average, on a single day, about 3% of all Web sites were involved in attacks (i.e., by being hosted on targeted IP addresses)."
"Put another way," said the report's principal investigator, "during this recent two-year period under study, the internet was targeted by nearly 30,000 attacks per day."

An anonymous reader writes: The operator of a 77,000-strong spam botnet was sentenced to two years probation and no prison time after admitting his crime and completely reforming his life. The former botnet operator is now working for a cybersecurity company, and admitted his actions as soon as the FBI knocked on his door back in 2013. The botnet operator, a 29-year-old from Santa Clara, California, says he was tricked by fellow co-schemers who told him they were not doing anything wrong by infecting computers with malware because they were not accessing private information such as banking or financial records. Furthermore, the botnet operator escaped prison time because he used all the money he earned in getting a college degree at Cal Poly instead of using it on a lavish lifestyle or drugs. This case is similar to the one that MalwareTech (aka Marcus Hutchins) now faces in the U.S. for his role in developing the Kronos trojan, but also after turning his life around and working as a cybersecurity researcher for years.

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."

According to new statistics released on Tuesday by Kaspersky Lab, a prominent Russian information security firm, 2017 is on track to beat 2016 -- and every year since 2011 -- in terms of the sheer number of computers infected with malware that installs mining software. From a report: So far in 2017, the company says it has detected 1.65 million infected machines. The total amount of infected computers for all of the previous year was roughly 1.8 million. The infected machines are not just home computers, the firm stated in a blog post, but company servers as well. "The main effect for a home computer or organization infrastructure is reduced system performance," Anton Ivanov, a security researcher for Kaspersky, wrote me in an email. "Also some miners could download modules from a threat actor's infrastructure, and these modules could contain other malware such as Trojans [malware that disguises itself as legitimate software]." Ivanov said that the firm doesn't know how much money has been made overall with this scheme, but a digital wallet for one mining botnet that the company identified currently contains over $200,000 USD.

An anonymous reader quotes a report from Krebs On Security: A half dozen technology and security companies -- some of them competitors -- issued the exact same press release today. This unusual level of cross-industry collaboration caps a successful effort to dismantle "WireX," an extraordinary new crime machine comprising tens of thousands of hacked Android mobile devices that was used this month to launch a series of massive cyber attacks. Experts involved in the takedown warn that WireX marks the emergence of a new class of attack tools that are more challenging to defend against and thus require broader industry cooperation to defeat. News of WireX's emergence first surfaced August 2, 2017, when a modest collection of hacked Android devices was first spotted conducting some fairly small online attacks. Less than two weeks later, however, the number of infected Android devices enslaved by WireX had ballooned to the tens of thousands. Experts tracking the attacks soon zeroed in on the malware that powers WireX: Approximately 300 different mobile apps scattered across Google's Play store that were mimicking seemingly innocuous programs, including video players, ringtones or simple tools such as file managers.

Experts involved in the takedown say it's not clear exactly how many Android devices may have been infected with WireX, in part because only a fraction of the overall infected systems were able to attack a target at any given time. Devices that were powered off would not attack, but those that were turned on with the device's screen locked could still carry on attacks in the background, they found. The identical press release that Akamai and other firms involved in the WireX takedown agreed to publish says the botnet infected a minimum of 70,000 Android systems, but Seaman says that figure is conservative.

UnderAttack writes: Over two days, the Internet Storm Center connected a default configured DVR to the internet, and rebooted it every 5 minutes in order to allow as many bots as possible to infect it. They detected about one successful attack (using the correct password xc3511) every 2 minutes. Most of the attackers were well known vulnerable devices. A year later, what used to be known as the "Mirai" botnet has branched out into many different variants. But it looks like much hyped "destructive" variants like Brickerbot had little or no impact.

An anonymous reader writes: A list of thousands of fully working Telnet credentials has been sitting online on Pastebin since June 11, credentials that can be used by botnet herders to increase the size of their DDoS cannons. The list includes an IP address, device username, and a password, and is mainly made up of default device credentials in the form of "admin:admin", "root:root", and other formats. There are 33,138 entries on the list, which recently became viral on Twitter after several high-profile security experts retweeted a link to it. During the past week, a security researcher has been working to find affected devices and notify owners or their ISPs. Following his work, only 2,174 devices still allow an attacker to log on via its Telnet port, and 1,775 of the published credentials still work. "There are devices on the list of which I never heard of," the researcher said, "and that makes the identification process much slower."

An anonymous reader shares a report: Last week, Twitter's security team purged nearly 90,000 fake accounts after outside researchers discovered a massive botnet peddling links to fake "dating" and "romance" services. The accounts had already generated more than 8.5 million posts aimed at driving users to a variety of subscription-based scam websites with promises of -- you guessed it -- hot internet sex. The accounts were first identified by ZeroFOX, a Baltimore-based security firm that specializes in social-media threat detection. The researchers dubbed the botnet "SIREN" after sea-nymphs described in Greek mythology as half-bird half-woman creatures whose sweet songs often lured horny, drunken sailors to their rocky deaths. ZeroFOX's research into SIREN offers a rare glimpse into how efficient scammers have become at bypassing Twitter's anti-spam techniques. Further, it demonstrates how effective these types of botnets can be: The since-deleted accounts collectively generated upwards of 30 million clicks -- easily trackable since the links all used Google's URL shortening service.

chicksdaddy writes from a report via The Security Ledger: After seeding the globe with hackable DVRs and webcams, Zhejiang Dahua Technology Co., Ltd. of Hangzhou, China will be working with the U.S. firm Synopsys to "enhance the security of its Internet of Things (IoT) devices and solutions." Dahua, based in Hangzhou, China said it will with Mountain View based Synopsys to "enhance the security of its Internet of Things (IoT) devices and solutions." In a joint statement, the companies said Dahua will be adopting secure "software development life cycle (SDLC) and supply chain" practices using Synopsys technologies in an effort to reduce the number of "vulnerabilities that can jeopardize our products," according to a statement attributed to Fu Liquan, Dahua's Chairman, The Security Ledger reports. Dahua's cameras and digital video recorders (DVRs) figured prominently in the Mirai botnet, which launched massive denial of service attacks against websites in Europe and the U.S., including the French web hosting firm OVH, security news site Krebsonsecurity.com and the New Hampshire based managed DNS provider Dyn. Cybercriminals behind the botnet apparently exploited an overflow vulnerability in the web interface for cameras and DVRs to gain access to the underlying Linux operating system and install the Mirai software, according to research by the firm Level3. In March, Dahua was called out for another, serious vulnerability in eleven models of video recorders and IP cameras. Namely: a back door account that gave remote attackers full control of vulnerable devices without the need to authenticate to the device. The flaw was first disclosed on the Full Disclosure mailing list and described as "like a damn Hollywood hack, click on one button and you are in."

An anonymous reader quotes VentureBeat: As of late Friday, after many of the deadlines threatening data deletion had passed, few victims had paid ransoms. According to Elliptic Enterprises, only about $94,000 worth of ransoms had been paid via Bitcoin, which works out to less than one in a thousand of the 300,000 victims who were reportedly affected by WannaCry... While not as bad as feared, ransomware (not to mention cybersecurity threats in general) isn't going away. Wired reported that the domain registered by Hutchins has been under intense denial-of-service attacks delivered by an army of IoT devices marshalled, zombie-like, by Mirai.

An anonymous reader writes: Researchers have detected a new worm that is spreading via SMB, but unlike the worm component of the WannaCry ransomware, this one is using seven NSA tools instead of two. Named EternalRocks, the worm seems to be in a phase where it is infecting victims and building its botnet, but not delivering any malware payload.

EternalRocks is far more complex than WannaCry's SMB worm. For starters, it uses a delayed installation process that waits 24 hours before completing the install, as a way to evade sandbox environments. Further, the worm also uses the exact same filenames as WannaCry in an attempt to fool researchers of its true origin, a reason why the worm has evaded researchers almost all week, despite the attention WannaCry payloads have received.

Last but not least, the worm does not have a killswitch domain, which means the worm can't be stopped unless its author desires so. Because of the way it was designed, it is trivial for the worm's owner to deliver any type of malware to any of the infected computers. Unfortunately, because of the way he used the DOUBLEPULSAR implant, one of the seven NSA hacking tools, other attackers can hijack its botnet and deliver their own malware as well. IOCs are available in a GitHub repo.
Ars Technica quotes security researchers who say "there are at least three different groups that have been leveraging the NSA exploit to infect enterprise networks since late April... These attacks demonstrate that many endpoints may still be compromised despite having installed the latest security patch."

An anonymous reader quotes CSO: As more groups get into the denial-of-service attack business they're starting to get in each other's way, according to a report released Thursday... There are only so many devices around that have the kind of vulnerabilities that make them potential targets for a botnet. That translates into a smaller average attack size, said Martin McKeay, senior security advocate at Cambridge, Mass.-based Akamai Technologies Inc. There are only so many devices around that have the kind of vulnerabilities that make them potential targets for a botnet. "And other people can come in and take over the device, and take those resources to feed their own botnet," he said. "I'm seeing that over and over."
The article reports a median size for DDoS attacks of 4 gigabits per second at the start of 2015 -- which droped in the first quarter of 2017 down to 500 megabits per second.

An anonymous reader writes:Thursday the FCC stopped accepting comments as part of long-standing rules "to provide FCC decision-makers with a period of repose during which they can reflect on the upcoming items" before their May 18th meeting. Techdirt wondered if this time to reflect would mean less lobbying from FCC Chairman Ajit Pai, but on Friday Pai recorded a Jimmy Kimmel-style video mocking mean tweets, with responses Gizmodo called "appalling" and implying "that anyone who opposes his cash grab for corporations is a moron."

Meanwhile, Wednesday The Consumerist reported the FCC's sole Democrat "is deploying some scorched-earth Microsoft Word table-making to use FCC Chair Ajit Pai's own words against him." (In 2014 Pai wrote "A dispute this fundamental is not for us five, unelected individuals to decide... We should also engage computer scientists, technologists, and other technical experts to tell us how they see the Internet's infrastructure and consumers' online experience evolving.") But Pai seemed to be mostly sticking to friendlier audiences, appearing with conservative podcasters from the Taxpayer Protection Alliance, the AEI think tank and The Daily Beast.
The Verge reports the flood of fake comments opposing Net Neutrality may have used names and addresses from a breach of 1.4 billion personal information records from marketing company River City Media. Reached on Facebook Messenger, one woman whose named was used "said she hadn't submitted any comments, didn't live at that address anymore and didn't even know what net neutrality is, let alone oppose it."

Techdirt adds "If you do still feel the need to comment, the EFF is doing what the FCC itself should do and has set up its own page at DearFCC.org to hold any comments."
