New research published this week could provide plenty of fresh fodder for Mirai, a malware strain that enslaves poorly-secured Internet of Things (IoT) devices for use in powerful online attacks. Researchers in Austria have unearthed a pair of backdoor accounts in more than 80 different IP camera models made by Sony Corp. Separately, Israeli security experts have discovered trivially exploitable weaknesses in nearly a half-million white-labeled IP camera models that are not currently sought out by Mirai.

Santa Claus —Another animated Get a Mac commercial featuring Santa Claus and Christmas caroling by both PC and Mac. PC spoils the group's singing of ' Santa Claus is Coming to Town ' by inserting 'Buy a PC and not a Mac this holiday season or any other time for goodness sake,' and claims, 'That's how I learned it.' Santa Claus Indoctrinism is the world-wide belief in Santa Claus which parents and the media force onto children so they will behave nicely. The belief goes: Santa Clause is a real person who lives in the North Pole, and he makes a list of every good boy and girl and every bad boy and girl, and then on Christmas Eve, he travels the world delivering presents to all the good boys and girls.
In a blog post published today, Austrian security firm SEC Consult said it found two apparent backdoor accounts in Sony IPELA Engine IP Cameras —devices mainly used by enterprises and authorities. According to SEC Consult, the two previously undocumented user accounts — named 'primana' and 'debug' — could be used by remote attackers to commandeer the Web server built into these devices, and then to enable 'telnet' on them.
Telnet — a protocol that allows remote logons over the Internet — is the very same communications method abused by Mirai, which constantly scours the Web for IoT devices with telnet enabled and protected by factory-default passwords.
'We believe that this backdoor was introduced by Sony developers on purpose (maybe as a way to debug the device during development or factory functional testing) and not an ‘unauthorized third party' like in other cases (e.g. the Juniper ScreenOS Backdoor, CVE-2015-7755),' SEC Consult wrote.
It's unclear precisely how many Sony IP cameras may be vulnerable, but a scan of the Web using Censys.io indicates there are at least 4,250 that are currently reachable over the Internet.

'Those Sony IPELA ENGINE IP camera devices are definitely reachable on the Internet and a potential target for Mirai-like botnets, but of course it depends on the network/firewall configuration,' said Johannes Greil, head of SEC Consult Vulnerability Lab. 'From our point of view, this is only the tip of the iceberg because it's only one search string from the device we have.'
Greil said there are other undocumented functionalities in the Sony IP cameras that could be maliciously used by malware or miscreants, such as commands that can be invoked to distort images and/or video recorded by the cameras, or a camera heating feature that could be abused to overheat the devices.
Sony did not respond to multiple requests for comment. But the researchers said Sony has quietly made available to its users an update that disables the backdoor accounts on the affected devices. However, users still need to manually update the firmware using a program called SNC Toolbox.
Greil said it seems likely that the backdoor accounts have been present in Sony cameras for at least four years, as there are signs that someone may have discovered the hidden accounts back in 2012 and attempted to crack the passwords then. SEC Consult's writeup on their findings is available here.
In other news, researchers at security firm Cybereason say they've found at least two previously unknown security flaws in dozens of IP camera families that are white-labeled under a number of different brands (and some without brands at all) that are available for purchase via places like eBay and Amazon. The devices are all administered with the password '888888,' and may be remotely accessible over the Internet if they are not protected behind a firewall. KrebsOnSecurity has confirmed that while the Mirai botnet currently includes this password in the combinations it tries, the username for this password is not part of Mirai's current configuration.
But Cybereason's team found that they could easily exploit these devices even if they were set up behind a firewall. That's because all of these cameras ship with a factory-default peer-to-peer (P2P) communications capability that enables remote 'cloud' access to the devices via the manufacturer's Web site — provided a customer visits the site and provides the unique camera ID stamped on the bottom of the devices.
Although it may seem that attackers would need physical access to the vulnerable devices in order to derive those unique camera IDs, Cybereason's principal security researcher Amit Serper said the company figured out a simple way to enumerate all possible camera IDs using the manufacturer's Web site.
'We reverse engineered these cameras so that we can use the manufacturer's own infrastructure to access them and do whatever we want,' Serper said. 'We can use the company's own cloud network and from there jump onto the customer's network.'
Lior Div, co-founder and CEO at Cybereason, said a review of the code built into these devices shows the manufacturer does not appear to have made security a priority, and that people using these devices should simply toss them in the trash.
'There is no firmware update mechanism built into these cameras, so there's no way to patch them,' Div said. 'The version of Linux running on these devices was in some cases 14 years old, and the other code libraries on the devices are just as ancient. These devices are so hopelessly broken from a security perspective that it's hard to really understand what's going on in the minds of people putting them together.'
Cybereason said it is not disclosing full technical details of the flaws because it would enable any attacker to compromise them for use in online attacks. But it has published a few tips that should help customers determine whether they have a vulnerable device. For example, the camera's password (888888) is printed on a sticker on the bottom of the devices, and the UID — also printed on the sticker — starts with one of these text strings:

'People tend to look down on IoT research and call it junk hacking,' Cybereason's Yoav Orot wrote in a blog post about its findings. 'But that isn't the right approach if researchers hope to prevent future Mirai botnet attacks. A smart (insert device here) is still a computer, regardless of its size. It has a processor, software and hardware and is vulnerable to malware just like a laptop or desktop. Whether the device records The Walking Dead or lets you watch your cat while you're at work, attackers can still own it. Researchers should work on junk hacking because these efforts can improve device security (and consumer security in the process), keep consumer products out of the garbage heap and prevent them from being used to carry out DDoS attacks.'
The discoveries by SEC Consult and Cybereason come as policymakers in Washington, D.C. are grappling with what to do about the existing and dawning surge in poorly-secured IoT devices. A blue-ribbon panel commissioned by President Obama issued a 90-page report last week full of cybersecurity policy recommendations for the 45th President of the United States, and IoT concerns and addressing distributeddenial-of-service (DDoS) attacks emerged as top action items in that report.
Meanwhile, Morning Consultreports that U.S. Federal Communications Commission Chairman Tom Wheeler has laid out an unexpected roadmap through which the agency could regulate the security of IoT devices. The proposed certification process was laid out in a response to a letter sent by Sen. Mark Warner (D-Va.) shortly after the IoT-based attacks in October that targeted Internet infrastructure company Dyn and knocked offline a number of the Web's top destinations for the better part of a day.
Morning Consult's Brendan Bordelon notes that while Wheeler is set to step down as chairman on Jan. 20, 'the new framework could be used to support legislation enhancing the FCC's ability to regulate IoT devices.'
There have been a lot of Bad movies in the 15 years since its release - Bad Teacher, Bad Moms, Bad Grandpaand so forth - but there's a reason that Bad Santa started this persistent but wildly uneven trend: it's very, very good. Picking up the thread that made Ghost World such a misanthropic delight, director Terry Zwigoff crafted a foul, ugly, hilariously funny anti-holiday classic that skillfully got to have its Advent Calendar candy corn and eat it too, thanks to a committed, deeply authentic performance by Billy Bob Thornton and an ensemble of supporting players who transformed what has become a one-liner of a concept - take something traditionally nice, and add as much profanity and filth as possible - into yuletide poetry.

There are three versions of the film - the theatrical cut, an unrated edition and a director's cut, the differences between which Matt Singer elucidates beautifully in this article on IFC. Zwigoff's version is, perhaps unsurprisingly, the most unrepentantly melancholy of the three; he removed not just comparatively more heartwarming elements like Willie's (Thornton) efforts to befriend young hapless Thurman (Brett Kelly), but many of its funnier moments because they undercut his specific intention for audiences to question whether or not they should laugh at a foul-mouthed, alcoholic criminal posing as Saint Nick. Unfortunately for him - though less so for us - the prevailing version, rated R or unrated, became so instantly iconic in its unrelenting meanness, so funny in its horrifying depiction of this same person mentoring a kid, much less regularly interacting with children, fucking a woman with a Santa Claus fetish, and generally abusing his body to extreme, disgusting ends, that it more or less immediately joined the canon of must-see holiday films and modern comedy classics, for adults anyway.
Thornton admits to having been drunk for 'some' of the filming of the movie, but his performance is so believable that it wouldn't come as a surprise if he'd had to check himself into a rehab facility afterward: where so many other portraits of boozy self-indulgence (or even self-destruction) seem vaguely romantic or appealing, he is seemingly imploding, withering away, or even actively killing himself with one binge after another. It must be extremely difficult to play a role like that where all of the feelings of a character are so clearly unhappy, but what is more remarkable is how all of that works in concert with what is extraordinary comedy writing: screenwriters Glenn Ficarra and John Requa, assisted by Zwigoff and producers Joel and Ethan Coen, craft a wicked, incisive movie around Willie about the vagaries of commercialism, the lengths to which greed and depravity will drive some people, and the generally unrelentingly cruelty of the world.
Willie and Marcus (Tony Cox) are crooks, but Marcus' wife Lois (Lauren Tom) gets in on the act, compiling great lists of merchandise from department stores for them to retrieve each season. Meanwhile, Gin Slagel (the late, great Bernie Mac) discovers their ruse at his boss Bob Chipeska's (the late and equally great John Ritter) behest, and decides to blackmail them into splitting their earnings with him. And poor Thurman, the literal snot-nosed 'C' student who befriends Willie and eventually takes him into his home, is first bullied relentlessly by older kids, then bullied by Willie into learning how to defend himself - with a screaming kick to the nuts. Rocket vs target mac os.
Kelly gives one of those performances you feel like isn't a performance at all - it's just who that kid is, or maybe who you hope he is given the emotional abuse he receives - but the movie recognizes how his, well, stupidity is one of the things that protects him from life's atomic wedgies. As Bob, the department store manager increasingly unsettled by Willie's job performance, and too squeamish - and afraid - to stand up to either him and Marcus or Gil, his chief of security, Ritter delivers an hysterical, nuanced performance that feels like authentic, milquetoast middle management - a guy who's paralyzed himself with too much sensitivity training to distinguish between right and wrong, at least for a department store Santa Claus. And as Gil, Mac expertly plays both sides, a still and certain despot who knows that his directness is intimidating to a spineless white man, even one who's his boss, and yet he's another bully, good at his job but less interested in policing bad behavior than figuring out a way to capitalize off of the people he's apprehended.
Movies like Zwigoff's aren't for everyone - there's only so much meanness that some people can stand - and depending on one's mood during the holiday season it can be an especially brutal viewing experience. (Tony Cox's insults as Marcus both manage to be endlessly astute - if never kind - and merciless, the result of an understanding of people, and human nature in general, wielded with the fury and power of a hatchet.) But revisiting the film 15 years later, after the copycats and imitators, Bad Santa still retains its misanthropic power, because of Thornton's incredible lead performance, a game ensemble cast and a concept that like Santa Claus himself manages to be funny, relevant, and timeless - a big, fat lump of coal in your stocking, always delivered right on time.
