In September, the company once again topped Ofcom's quarterly whinge list for the most moaned-about fixed line broadband provider in Blighty. BT also owns Plusnet, the second most complained about provider.On average, each week 14,000 consumers and small businesses waited longer than they should for broadband and phone line repairs and a further 11,000 experienced late installations, according to Consumer Advice.By hiring more customer service staff it hopes to answer “more than” 90 per cent of customer calls by March 2017.Libby Barr, managing director of customer care at BT Consumer, said: “We are going to answer 90 per cent of our customers’ calls in the UK and Ireland by the end of March, and we have been taking on great people to fill full time jobs working for BT. In fact, we will be recruiting for an extra 500 positions, which will be a dramatic increase in what we said we’d do.“We can offer the chance to join a business that is transforming its service and investing in brilliant and motivated people in the UK and Ireland. There are opportunities to earn £500 by referring a friend and also openings for agency advisors who want to work for BT directly.” ®
Former Expedia worker Jonathan Ly has admitted to hacking his own chief financial officer and investor relations head to commit US$331,000 in insider stock-trading.Ly, 28, of San Francisco, pleaded guilty to securities fraud in a Seattle District Court and faces up to 25 years prison and a US$375,907 settlement including some US$81,592 in repayments for expenses Expedia incurred during its investigation.All told Ly is said to have made US$331,000 in net profit through the securities trades.The former senior support technician used his remote login credentials and those of others he was supplied during his job to access the data.Prosecutors say he also used the credentials of other employees to mask his intrusions.Ly is accused of stealing the information over the three years to 2016 including market speculation about pending announcements which helped the hacker gain an edge in his share trading efforts.Prosecutors say Ly continued to plunder Expedia after he voluntarily left the company last year using software loaded onto a corporate laptop still in his possession.CNN reports that Ly's lawyer, John Runfola, says his client is "deeply sorry" and has "certainly learned his lesson".Gatford instructed your reporter to visit the burger barn because he practices a form of penetration testing called "red teaming", wherein consultants attack clients using techniques limited only by their imagination, ingenuity, and bravado.
He wanted me to break the burger-builder to probe my weaknesses before he would let The Register ride along on a red-team raid aimed at breaking into the supposedly secure headquarters of a major property chain worth hundreds of millions of dollars.Before we try for that target, Gatford, director of penetrations testing firm HackLabs, wants to know if I will give the game away during a social engineering exploit. So when the McDonald's computer turns out to have been fixed and my fake system administrator act cancelled, we visit an office building's lobby where Gatford challenges me to break into a small glass-walled room containing a shabby-looking ATM.I can't see a way into the locked room. I think I see a security camera peering down from the roof, but later on I'm not sure I did. I can't think of a way in and I'm trying to look so casual I know I'm certain to look nervous.
Time's up. Gatford is finished with the lobby clerk. He asks how I would get in, and hints in my silence that the door responds to heat sensors.I mutter something stupid about using a hair dryer. Gatford laughs and reminds me about heat packs you'd slip into gloves or ski boots. "Slide one of those under the crack," he says.I've failed that test but stayed cool, so Gatford decides he's happy to have me along on a red-team raid, if only because red teams seldom face significant resistance. Costume is therefore an important element of a red team raid. For this raid, our software exploits are suits and clipboards. Sometimes it's high-visibility tradie vests, hard hats, or anything that makes a security tester appear legitimate.Once dressed for the part, practitioners use social-engineering skills to manipulate staff into doing their bidding. Fans of Mr Robot may recall an episode where the protagonist uses social engineering to gain access to a highly secure data centre; this is red teaming stylised. Think a real-world capture the flag where the flags are located in the CEO's office, the guard office, and highly secure areas behind multiple layers of locked doors.
Only one manager, usually the CEO of the target company, tends to know an operation is afoot. Limited knowledge, or black-box testing, is critical to examine the real defences of an organisation. Red teamers are typically not told anything outside of the barebones criteria of the job, while staff know nothing at all. It catches tech teams off guard and can make them look bad. Gatford is not the only tester forced to calm irate staff with the same social engineering manipulation he uses to breach defences.Red teamers almost always win, pushing some to more audacious attacks. Vulture South knows of one Australian team busted by police after the black-clad hackers abseiled down from the roof of a data centre with Go-Pro cameras strapped to their heads.Across the Pacific, veteran security tester Charles Henderson tells of how years back he exited a warehouse after a red-teaming job. "I was walking out to leave and I looked over and saw this truck," Henderson says. "It was full of the company's disks ready to be shredded. The keys were in it." Henderson phoned the CEO and asked if the truck was in-scope, a term signalling a green light for penetration testers. It was, and if it weren't for a potential call to police, he would have hopped into the cab and drove off. Henderson now leads IBM's new red-teaming unit in the United States, which he also built from the ground up.

"There are some instances where criminal law makes little distinction between actions and intent, placing red teams in predicaments during an assignment, particularly when performing physical intrusion tasks," Nathaniel Carew and Michael McKinnon from Sense of Security's Melbourne office say. "They should always ensure they carry with them a letter of authority from the enterprise."Your reporter has, over pints with the hacking community, heard many stories of law enforcement showing up during red-team ops. One Australian was sitting off a site staring through a military-grade sniper scope, only to have a cop tap on the window. Gatford some years ago found himself face-to-face in a small room with a massive industrial furnace while taking a wrong turn on a red-team assignment at a NSW utility. He and his colleagues were dressed in suits. Another tester on an assignment in the Middle East was detained for a day by AK-47-wielding guards after the CEO failed to answer the phone. Red teamers have been stopped by police in London, Sydney, and Quebec, The Register hears.
One of Australia's notably talented red teamers told of how he completely compromised a huge gaming company using his laptop and mobile phone. Whether red teaming on site or behind the keyboard, the mission is the same: breach by any means necessary.So say researchers with Cybereason, who claim a pair of high-profile vulnerabilities they spotted in surveillance cams two years ago have been completely ignored by vendors – thus leaving the door wide open for miscreants to hijack potentially "hundreds of thousands" of devices and use them for attacks.Cybereason's Amit Serper says he and fellow researcher Yoav Orot exploited flaws in off-the-shelf internet-connected cameras back in 2014 in an effort to show how poor IoT security was at the time.Since then, Serper says, the bugs have not only gone unpatched, but the insecure code has popped up in network camera firmware shipped by dozens of manufacturers selling their weak wares on Amazon. The Cybereason pair finger VStarcam as one vendor of vulnerable kit."I’m also not releasing the names of all the camera vendors," said Serper. "This would encourage hackers to look for the software flaws. I named VStarcam since their cameras are readily available from eBay and Amazon. Their cameras are also sold under the name Eye4."
You can use this handy web widget to find out if you have an insecure cam from its serial number and other bits of information."Most of the cameras run older versions of Linux, like version 2.6.26, while a few run the most recent version from around 3.0 and up," Serper continued."While the OS is somewhat modern, all the cameras were running extremely old and vulnerable software ... the web server software found in many of the cameras, for example, was from around 2002."Thanks to programming blunders left in this crusty old code, attackers can bypass authentication checks to access the camera's stored files and pull the administrator password. From there, the camera's web server could be accessed and a second exploit could be used to gain root privileges that would allow the hacker complete control over the camera, including the ability to execute code, spy on the hardware's owners, and pressgang the cam into joining a botnet.Serper notes that even if the dozens of different camera vendors using this vulnerable software were to deploy the fix, cameras already in use would remain vulnerable, as they lack the ability to properly receive and install software updates.
Thus, the only solution to fully close the flaw is to throw out the cameras and buy units with patched software. Below is a video showing how easy it is to exploit an at-risk, internet-facing surveillance camera remotely. While these flaws are a serious issue on their own, Serper says that they reflect an even larger problem: the ongoing lack of proper security practices and patching techniques on the part of IoT hardware manufacturers and the researchers who help them find and fix holes."A smart (insert device here) is still a computer, regardless of its size. It has a processor, software and hardware and is therefore vulnerable to malware just like a laptop or desktop," Serper explained.When was the last time your smart thermostat, lights, hub, camera, or power socket was updated? If it was a while ago, you may want to think about chucking it in the garbage.That's according to DNS mage and security expert Paul Vixie, who has been using his status in the internet world to increasingly warn about the dangers posed by the internet of things.In a recent keynote and an interview posted on the Internet Society's blog, Vixie the pragmatic engineer has started the push for actual solutions to months of "something must be done" hand-wringing by policy wonks.

The recent DDoS attacks using internet-connected cameras with terrible security to take down part of the DNS has only added pressure. So far, that pressure has been in the least useful direction: a multitude of different organizations, standards bodies and government agencies all pushing themselves as the solution without producing a useful product.In the medium term, Vixie puts his weight behind the idea of recognized safety standard organization Underwriters Laboratories (UL). You can find UL markings on pretty much every electrical product in the United States – in the UK, the equivalent is the Kitemark – from electrical sockets to kettles.Back in April, UL announced a new Cybersecurity Assurance Program (UL CAP) and Vixie is behind the idea. "It used to be that if you were going to buy a toaster for your kitchen, you would make sure it was on the UL list to make sure it wasn’t going to start a fire in your house," he notes. "So, we need to get there with Internet-enabled devices. I am glad UL is going to do that."As many others have noted, the problem is not going to go away, because of the expanding market, the fact it is so easy to connect something to the internet, and the rewards that exist in getting to market fast (and conversely the risk in taking too long). Some security experts, including Bruce Schneier, have been arguing for legislation to introduce minimum security standards before the problem gets out of control. Vixie appears to agree: "Regulation isn't always the right answer, but I think that in this case, the only way we're going to get wide-spread improvement of software quality is if being a little later to market or costing a little more doesn't make your product uncompetitive – because your competitors have to meet the same quality standards as you do."
