Those tenders were hoovered up by a rival which used the information to get a cheap head-start on the company.Another individual had blueprints for a new communications system stolen when he was invited to speak on the subject at a foreign industry conference.Ronaldson advised enterprises to enforce a privacy lockdown on executives' social media accounts such as Facebook if the high fliers insist on sharing travel information such as their check-in to airlines' frequent flyer lounges.He says all devices taken on overseas trips must be quarantined before they are connected to corporate networks to mitigate the very real risk of compromise.For best practice, top executives should leave their personal and corporate devices at home and travel with burner phones and laptops.Before you go on your business trip, know the adversary has already watched you, already knows your flight, knows that you love going to the lounge and watching the footy, and that you put your bag down and go for a drink. The specification means makers of USB devices will be able to encode them with information about their source and function. When connecting to those devices, machines like computers or phones will be able to read that descriptor and choose to connect, or not, depending on policies.

The USB 3.0 Promoter group says “For a traveler concerned about charging their phone at a public terminal, their phone can implement a policy only allowing charge from certified USB chargers.” Or perhaps you're worried that your organisation's laptop fleet could be compromised by rogue USB devices, in which case you “can set a policy in its PCs granting access only to verified USB storage devices.” It's not clear if that will allow organisations to specify individual devices, or just devices whose manufacturers have implemented the spec.USB-C needs this spec for two reasons. One is that, not to put to fine a point on it, users are idiots. How else to explain the fact that almost half the people who pick up a USB stick they happen across in a parking lot plug said drives into their PCs. Once USB-C becomes ubiquitous and makes a single wire responsible for carrying power and data, even the dimmest hackers will likely cotton on to the opportunities to craft crooked chargers or other evil devices.The second is that there are lots of scumbags churning out second-rate electronics to make a quick buck. We already know that poorly-wired cables capable of frying kit are enough of a menace that Amazon.com recently banned the sale of non-compliant cables on its digital tat bazaar. If devices flag such kit as sub-standard, or refuse to connect to them, it's therefore a win for all but the junk-slingers.

Details of the spec can be found in the revised USB 3.1 spec (54MB .ZIP file. Feel free to trawl through it for the finer points of the authentication. The TL:DR version is that it “references existing internationally-accepted cryptographic methods for certificate format, digital signing, hash and random number generation,” so it sounds like a conventional issue-certificates-and-check-them caper.Doubtless the revised spec explains the efforts folks behind it tried to make the authentication bullet-proof. And as sure as night follows day, efforts to find loopholes in the spec that make it possible to crank out fake kit that presents itself as authentic will surely commence.A bunch of Samsung Galaxy variants leave their modems open to receiving AT commands over the USB cable, even when they're locked.Before you dismiss the vulnerability as a local privilege escalation (which it is), consider how many people would be happy leaving a locked phone on their desk because you need the code to unlock it.The researchers, Roberto Paleari and Aristide Fattori, write that when connected to a laptop via the USB cable, the phones either automatically expose, or can be forced to expose, a serial interface that communicates with the USB modem.

“This communication channel is active even when both USB tethering and USB debugging (i.e., ADB) are disabled,” they write, “and can be accessed even when the device is locked. An attacker who gains physical access to a (possibly locked) device can thus use this interface to send arbitrary AT commands to the modem. This permits to perform several actions that should be forbidden by the lock mechanism, including placing phone calls or sending SMS messages.”Older devices expose the USB serial modem by default – for example, it turns up on a Linux laptop in /dev as a TTY device. For newer units, the attacker would have to switch the device to USB configuration number 2 – but the phone doesn't have to be unlocked for that to happen, as the researchers explain:“For our PoC we developed a very rough C tool, usbswitcher, that switches any attached Samsung device to USB configuration #2 (this is fine for the devices we tested, but your mileage might vary). The tool uses libusb to do the job, but the same task can probably be accomplished using the /sys/bus/usb pseudo-filesystem. The trick we used to force the phone to switch the configuration is to first reset the USB device (via usb_reset()), and then switching the configuration (via usb_set_configuration()). Sometimes it doesn't work at the first try, so just run usbswitcher twice to ensure the configuration is switched properly :-)”

On newer phones, the researchers say, the most dangerous vulnerability – that the attacker can get access to the Android userspace – has been plugged. An attacker can still, however, place calls and send text messages.On older devices (their example is an S4 mini), commands can be used to abuse some Android settings. For example, the AT+USBDEBUG command enables USB debugging, and AT+WIFIVALUE enables the device's Wi-Fi.ACSC 2016 Australians are having their retirement savings accounts drained as hackers move to breach broker platforms rather than the tougher target that is banking infrastructure.The Australian Federal Police AFP are investigating a spike in breaches against devices used by brokers who administer boutique, self-managed superannuation funds. Some brokers manage hundreds of such funds, a service that helps investors who think they can do better by picking their own retirement savings-boosters instead of relying on a larger fund.Self-managing a fund may be financially prudent. But the AFP warns that service providers are not as security-savvy as large superannuation funds.

“Some of these brokers are running Bittorrent, Counterstrike, and then logging into broker software and managing hundreds of accounts,” Australian Federal Police cybercrime team leader Scott Mellis told The Register.The easy target that is a poorly-managed PC means criminals have “tried their trojans and are now moving away from targeting banks,” Mellis added.Mellis says breached brokers have fixed their poor security postures after being notified by the Federal Police.Australians can withdraw superannuation funds before the age of 55 only under limited circumstances.The Australian Securities and Investments Commission says scammers exploit this allowance by using stolen identity credentials to set up self-managed super funds where balances and be transferred and then withdrawn.The free HTTPS certificate service says that not much will change, other than shedding the beta label.Since our beta began in September 2015 we've issued more than 1.7 million certificates for more than 3.8 million websites, the team said on Tuesday.

We've gained tremendous operational experience and confidence in our systems. The beta label is simply not necessary any more.Along with dropping its beta label, Let's Encrypt announced Tuesday that it had signed a fresh round of sponsorship deals, including one with Hewlett Packard Enterprise, which will be joining as a silver sponsor. Meanwhile, Cisco and Akamai renewed their platinum sponsor agreements and Gemalto said it would be backing Let's Encrypt as a gold sponsor. The snafu stemmed from a database crash. Problems first surfaced at 1000 UTC (1100 BST) on Monday and dragged on until lunchtime on Tuesday, as detailed in a series of updates to Symantec.cloud’s client portal (extract below) from Tuesday breakfasttime.Our engineers have advised that the database restoration process is nearing completion with error checking and analysis to follow. Our infrastructure team continue to investigate all possible options to bring the service to production as quickly as possible. Please accept our profuse apologies for any inconvenience caused. The glitch affected access to the portal and therefore affected customers’ ability to manage their accounts. El Reg understands that the message filtering service offered by Symantec.cloud (formerly MessageLabs) nonetheless operated as normal.

Without this you cannot register/remove email addresses or perform any changes, Jon, one of two Reg readers who notified us about issues, commented. Apparently the $6bn company only has one copy of their Portal database.UK spy agency GCHQ tried to prevent a Harry Potter book from being leaked online, according to its publisher.Reminding people that the listening post doesn't use its extraordinary broad powers solely in the pursuit of terrorism, publisher Nigel Newton of Bloomsbury recalled how he was approached in 2005 by GCHQ after the snoops thought they discovered an early copy of The Half Blood-Prince online.Someone from GCHQ then read out a page from the book to an editor, who said it was actually fake, Newton told Australia's ABC radio. The Sunday Times asked GCHQ for a comment and it responded: We don't comment on our defense against the dark arts.Which is pretty funny if you choose to forget that the agency claims it scours the internet and stores vast databases of information on everyone solely in the pursuit of, er, serious crime and terrorism. IBM Watson Health has closed its $2.6bn acquisition of Truven Health Analytics. The deal is set to bring medical data into Big Blue's health-data business arm, specifically covering cost, claims, quality and outcomes information. El Reg has provided more information on the acquisition here.
