An anonymous reader writes "A 2011 ProPublica series found that the TSA had glossed over the small cancer risk posed by its X-ray body scanners at airports across the country. While countries in Europe have long prohibited the scanners, the TSA is just now getting around to studying the health effects." I'm not worried; the posters and recorded announcements at the airport say these scanners raise no health concerns.

DECula writes "In a move not communicated to its users beforehand, Google's Gmail servers were reconfigured to not connect to remote pop3 servers that have self-signed certificates, leaving folks with unencrypted connections, or no service when getting email from other services. Not good for the small folks. One suggestion was to allow placing the public keys on Google's side in the user configuration. That would be a heck of a lot better than just dropping users into never never land." Apparently, "valid" now means "paid someone Google approves to sign the certificate." It's not like commercial CAs have the best security track record either.
nonprofiteer writes "Two years ago, Visa, MasterCard, PayPal, Western Union and Bank of America cut off all funding to WikiLeaks. A group of free information advocates wants to prevent a similar financial blockade on information from happening again. Daniel Ellsberg, John Perry Barlow, and EFF staffers are founding the Freedom of the Press Foundation, an org that will raise money and channel it to edgy media groups that might suffer from a WikiLeaks-style embargo. When donors give to the Foundation, they can choose to have their funding passed on to any media group under the Foundation's umbrella (currently WikiLeaks, Muckrock, The National Security Archives and UpTake). That strategy aims to make it harder to cut funding to any of those organizations, or any added in the future. And because the site is encrypted, donors who worry about being identified as giving to any particularly controversial group can do so without being identified. It's like Tor for charitable giving."
CowboyRobot writes "Columbia University grad student Ang Cui demonstrated how networked printers and phones can be abused by attackers. 'The attack I demonstrated is caused by the multiple vulnerabilities within the syscall interface of the CNU [Cisco Native Unix] kernel,' Cui tells Dark Reading. 'It is caused by the lack of input validation at the syscall interface, which allows arbitrary modification of kernel memory from userland, as well as arbitrary code execution within the kernel. This, in turn, allows the attacker to become root, gain control over the DSP [Digital Signal Processor], buttons, and LEDs on the phone. The attack I demonstrated patches the existing kernel and DSP in order to carry out stealthy mic exfiltration.'"
An anonymous reader writes "A huge security hole has been discovered in recent Samsung devices including phones like the Galaxy S2 and S3. It is possible for every user to obtain root due to a custom faulty memory device created by Samsung." The problem affects phones with the Exynos System-on-Chip.

Albanach writes "At the start of November Slashdot reported the discovery of a code, thought to be from the Second World War, found attached to the leg of a pigeon skeleton located in an English chimney. Now a Canadian by the name of Gord Young claims to have deciphered the message in less than 20 minutes. He believes that the message is comprised mostly of acronyms."
chicksdaddy writes "The newly discovered Dexter malware is one of the few examples of a malicious program that targets point of sale terminals, but also communicates, botnet-like, with a command and control infrastructure. According to an analysis by Seculert, the custom malware has infected 'hundreds POS systems' including those operated by 'big-name retailers, hotels, restaurants and even private parking providers.' Now a detailed analysis by Verizon's RISK team suggests that Dexter may be a creation of a group responsible for the ubiquitous Zeus banking Trojan. By analyzing early variants of Dexter discovered in the wild, Verizon determined that the IP addresses used for Dexter's command and control were also used to host Zeus-related domains and several domains for Vobfus, also known as 'the porn worm,' which has been used to deliver the Zeus malware. Verizon also produced some tantalizing clues as to the identity of one individual who may be a part of the crew responsible for the malware. The RISK team linked the domain registration for a Dexter C&C server to an unusual online handle, 'hgfrfv,' that was used to post a number of suggestive help requests ('need help with decrypting a table encrypted with EncryptByKey') in online technical forums, where a live.com e-mail address was also provided. The account name was also linked to a shell account on the outsourcing web site freelancer.com, which lists 'hgfrfv' as an individual residing in the Russian Federation."
First time accepted submitter veganboyjosh writes "I got an instant message from an uncle the other day, asking me what was in the link I sent him. I hadn't sent him a link so I figured that his account had been hacked and he'd received a malicious link from some bot address with my name in the 'From' box. This was confirmed when he told me the address the link had come from. When I tried explaining what the link was, that his account had been hacked, and that he should change the password to his @aol.com email account, his response was 'No, I think your account was hacked, since the email came from you.' I went over it again, with a real-life analog of someone calling him on the phone and pretending to be me, but I'm not sure if that sunk in or not. This uncle is far from tech savvy. He's in his 60s, and uses Facebook several times a week. He knows I'm online much more and kind of know my way around. After his initial response, I didn't have it in me to get into the whole 'Never click a link from an unfamiliar email address' bit; to him, this wasn't an unfamiliar email address, it was mine. How do I explain this to him, and what else should I feel responsible for telling him?"
CowboyRobot writes "Earlier this year, the state's Department of Revenue was storing 3.3 million bank account numbers, as well as 3.8 million tax returns containing Social Security numbers for 1.9 million children and other dependents, in an unencrypted format. After a state employee clicked on a malicious email link, an attacker was able to obtain copies of those records. It's easy to blame the breach on 'Russian hackers' but who is really to blame? 'The state's leadership, from the governor on down, failed to take information security seriously or to correctly gauge the financial risk involved. As a result, taxpayers will pay extra to clean up the mess. Beyond the $800,000 that the state will spend — and should have already spent — to improve its information security systems, $500,000 will go to the data breach investigation, $740,000 to notify consumers and businesses, $250,000 for legal and PR help, and $12 million for identity theft monitoring services.'"
An anonymous reader writes "It's been found that the Btrfs file-system is vulnerable to a Hash-DOS attack, a denial-of-service attack caused by hash collisions within the file-system. Two DOS attack vectors were uncovered by Pascal Junod that he described as causing astonishing and unexpected success. It's hoped that the security vulnerability will be fixed for the next Linux kernel release." The article points out that these exploits require local access.
An anonymous reader writes "Google on Friday announced it is shutting down a slew of features and services as part of its winter cleaning. Google Calendar will be losing a few features, Google Sync will be axed (on the consumer side), as will Google Calendar Sync, SyncML, the Issue Tracker Data API, and the Punchd app."
An anonymous reader writes "Researchers of the International Computer Science Institute in Berkeley have created an interactive diagram that shows root-CAs, their intermediates, the relationships between them and how many certificates have been signed by them. The graph was generated by passively monitoring the Internet uplinks of a number of (mostly) edu sites for SSL connections and their certificate Information. Among other things the graph shows that one GoDaddy intermediate signed more than 74,000 certificates and that a German CA uses more than 200 sub-CAs for administrative reasons."
CowboyRobot writes "A new targeted attack campaign with apparent Korean ties has been stealing email and Facebook credentials and other user-profile information from Russian telecommunications, IT, and space research organizations. The attackers are grabbing email user accounts and passwords from Outlook, as well as information about the victims' email server."
