Spamhaus victim of BGP route hijacking
Pretty major hi-jinks. Neil Schwartzman says it didn't go on for long, but still, this is crazy antics.

As can seen from the BGP output, we were using a /32 route going over AS 34109. This was highly suspicious for two reasons. First, a /32 route refers only to a single IP address. Except in special cases, routes are normally /24 (256 hosts) or larger. Second, the AS 34109 belongs to CB3ROB which is an Internet provider that has actually been in conflict with Spamhaus (see: spamhaus; allspammedup; theregister). Certainly they weren’t running a legitimate Spamhaus server. It seems clear that the CB3ROB network hijacked one (or more) of the IP addresses of Spamhaus, and installed a DNS server there which incorrectly returns positive results to every query. The result causes harm to Spamhaus users and their customers, making Spamhaus unusable for anyone unable to correct the problem as we did, and perhaps even undermining the credibility of Spamhaus itself.

Romania believes rival nation behind MiniDuke cyber attack | Reuters
"It is a cyber attack ... pursued by an entity that has the characteristics of a state actor," [Romanian secret service] SRI spokesman Sorin Sava told Reuters [...]. "Our estimations show the attack is certainly relevant to Romania's national security taking into account the profile of the compromised entities." [...]

In this case, computer experts say an attacker from the former Soviet Union could be more likely. "MiniDuke" in some ways resembles a banking fraud Trojan dubbed "TinBa" believed to have been created by Russian criminal hackers.

Irish government attacked using 'MiniDuke' PDF malware
although I haven't seen a word of it in the Irish media yet -- wonder if the government have noticed?
Cyber criminals have targeted government officials in more than 20 countries, including Ireland and Romania, in a complex online assault seen rarely since the turn of the millennium. The attack, dubbed "MiniDuke" by researchers, has infected government computers as recently as this week in an attempt to steal geopolitical intelligence, according to security experts.

java - Given that HashMaps in jdk1.6 and above cause problems with multi-threading, how should I fix my code - Stack Overflow
Massive Java concurrency fail in recent 1.6 and 1.7 JDK releases -- the java.util.HashMap type now spin-locks on an AtomicLong in its constructor.

Here's the response from the author: 'I'll acknowledge right up front that the initialization of hashSeed is a bottleneck but it is not one we expected to be a problem since it only happens once per Hash Map instance. For this code to be a bottleneck you would have to be creating hundreds or thousands of hash maps per second. This is certainly not typical. Is there really a valid reason for your application to be doing this? How long do these hash maps live?'

Oh dear. Assumptions of "typical" like this are not how you design a fundamental data structure. fail. For now there is a hacky reflection-based workaround, but this is lame and needs to be fixed as soon as possible. (Via cscotta)

IPMI: Freight Train To Hell
'Intel's Intelligent Platform Management Interface (IPMI), which is implemented and added onto by all server vendors, grant system administrators with a means to manage their hardware in an Out of Band (OOB) or Lights Out Management (LOM) fashion. However there are a series of design, utilization, and vendor issues that cause complex, pervasive, and serious security infrastructure problems.

The BMC is an embedded computer on the motherboard that implements IPMI; it enjoys an asymmetrical relationship with its host, with the BMC able to gain full control of memory and I/O, while the server is both blind and impotent against the BMC. Compromised servers have full access to the private IPMI network

The BMC uses reusable passwords that are infrequently changed, widely shared among servers, and stored in clear text in its storage. The passwords may be disclosed with an attack on the server, over the network network against the BMC, or with a physical attack against the motherboard (including after the server has been decommissioned.)

IT's reliance on IPMI to reduce costs, the near-complete lack of research, 3rd party products, or vendor documentation on IPMI and the BMC security, and the permanent nature of the BMC on the motherboard make it currently very difficult to defend, fix or remediate against these issues.'

fail0verflow ::
Excellent demo of how use of a block cipher with a known secret key makes an insecure MAC. "In short, CBC-MAC is a Message Authentication Code, not a strong hash function. While MACs can be built out of hash functions (e.g. HMAC), and hash functions can be built out of block ciphers like AES, not all MACs are also hash functions. CBC-MAC in particular is completely unsuitable for use as a hash function, because it only allows two parties with knowledge of a particular secret key to securely transmit messages between each other. Anyone with knowledge of that key can forge the messages in a way that keeps the MAC (“hash value”) the same. All you have to do is run the forged message through CBC-MAC as usual, then use the AES decryption operation on the original hash value to find the last intermediate state. XORing this state with the CBC-MAC for the forged message yields a new block of data which, when appended to the forged message, will cause it to have the original hash value. Because the input is taken backwards, you can either modify the first block of the file, or just run the hash function backwards until you reach the block that you want to modify. You can make a forged file pass the hash check as long as you can modify an arbitrary aligned 16-byte block in it."

SipHash: a fast short-input PRF
a family of pseudorandom functions optimized for short inputs. Target applications include network traffic authentication and hash-table lookups protected against hash-flooding denials-of-service attacks.

SipHash is simpler than MACs based on universal hashing, and faster on short inputs.

Compared to dedicated designs for hash-table lookup, SipHash has well-defined security goals and competitive performance. For example, SipHash processes a 16-byte input with a fresh key in 140 cycles on an AMD FX-8150 processor, which is much faster than state-of-the-art MACs.

How to make a security geek feel very old: #Factorisation, #DKIM and @DrZacharyHarris
“A 384-bit key I can factor on my laptop in 24 hours. The 512-bit keys I can factor in about 72 hours using Amazon Web Services for $75. And I did do a number of those. Then there are the 768-bit keys. Those are not factorable by a normal person like me with my resources alone. But the government of Iran probably could, or a large group with sufficient computing resources could pull it off.”

Remember when we thought 512-bit keys would be enough? how time flies!

Of course, John Aycock raised this problem back in 2007, although he assumed it'd take a 100,000-host botnet to crack them (in 153 minutes).

Chip and Skim: cloning EMV cards with the pre-play attack
Worrying stuff from the LBT team. ATM RNGs are predictable, and can be spoofed by intermediate parties:

'So far we have performed more than 1000 transactions at more than 20 ATMs and a number of POS terminals, and are collating a data set for statistical analysis. We have developed a passive transaction logger which can be integrated into the substrate of a real bank card, which records up to 100 unpredictable numbers in its EEPROM. Our analysis is ongoing but so far we have established non-uniformity of unpredictable numbers in half of the ATMs we have looked at.

First, there is an easier attack than predicting the RNG. Since the unpredictable number is generated by the terminal but the relying party is the issuing bank, any intermediate party – from POS terminal software, to payment switches, or a middleman on the phone line – can intercept and superimpose their own choice of UN. Attacks such as those of Nohl and Roth, and MWR Labs show that POS terminals can be remotely hacked simply by inserting a sabotaged smartcard into the terminal.

Lessons in website security anti-patterns by Tesco
Troy Hunt, an Aussie software architect working on a .Net security product called ASafaWeb, does a great job extensively deconstructing Tesco's appalling website security on their shopping site. In the process, he gets this wonderful tweet from their customer-care account:

"@troyhunt Let me assure you that all customer passwords are stored securely & in line with industry standards across online retailers."

As he says, this is a clear demonstration that Tesco is in the first stage of the four stages of competence -- "unconscious incompetence": "The individual does not understand or know how to do something and does not necessarily recognise the deficit."

'Poisoning Attacks against Support Vector Machines', Battista Biggio, Blaine Nelson, Pavel Laskov
The perils of auto-training SVMs on unvetted input.
We investigate a family of poisoning attacks against Support Vector Machines (SVM). Such attacks inject specially crafted training data that increases the SVM's test error. Central to the motivation for these attacks is the fact that most learning algorithms assume that their training data comes from a natural or well-behaved distribution. However, this assumption does not generally hold in security-sensitive settings. As we demonstrate, an intelligent adversary can, to some extent, predict the change of the SVM's decision function due to malicious input and use this ability to construct malicious data. The proposed attack uses a gradient ascent strategy in which the gradient is computed based on properties of the SVM's optimal solution. This method can be kernelized and enables the attack to be constructed in the input space even for non-linear kernels. We experimentally demonstrate that our gradient ascent procedure reliably identifies good local maxima of the non-convex validation error surface, which significantly increases the classifier's test error.

'The company, called Silent Circle, will launch later this year, when $20 a month will buy you encrypted email, text messages, phone calls, and videoconferencing in a package that looks to be strong enough to have the NSA seriously worried. Zimmermann says that surveillance by the state and others has increased vastly over the last few years, and privacy improvement are again needed. "At the very least I want people, as part of their right in a free society to be able to communicate securely," he said in a promotional video. "I should be able to whisper in your ear, even if your ear is a thousand miles away." [...] While software can handle most of the work, there still needs to be a small backend of servers to handle traffic. The company surveyed the state of privacy laws around the world and found that the top three choices were Switzerland, Iceland, and Canada, so they went for the one within driving distance.'

Digital Rights Forum - Online Privacy
'The Digital Rights Forum is a public debate on the important issues surrounding digital rights, with each event designed around the general over-arching topic of digital rights, puls a more narrowly focused subject. On Friday, the 18th of May, the forum will tackle the issue of Online Privacy.

With our lives ever more integrated with the web and social media, staying safe online is becoming an increasing concern to everyone. From mobile apps to websites and email, protecting our personal information and online privacy has never been more complicated and more important. Faced with software vulnerabilities such as contacts being leaked onto the Internet by mobile application providers, the increasing push toward revealing more private and personal information on social networks, and attempts by some to protect their businesses through litigation or processes which require the disclosure of personal information, the modern digital landscape has made protecting one's privacy more difficult than ever before.

With this in mind, this Digital Rights Forum will discuss the current state of data protection and online privacy in the current context of social networks and mobile applications.'

Bug #885027 in calibre: “SUID Mount Helper has 5 Major Vulnerabilities”
Amazing response to a security bug report. 'what's happening in this bug report right now is a perfect example of how *not* to do security response. When faced with two people who clearly know a few things about secure coding, rather than taking their advice and actually fixing the root cause of the problem (or abandon it as a hopeless situation, which is probably the more appropriate response), you've chosen to waste our time by demanding that we write weaponized exploits to exploit what most people already know to be exploitable. To top it off, when shown repeatedly how your half-baked "fixes" don't actually fix anything, rather than taking our advice you just add another small hurdle that can be trivially bypassed. It would be sad if it weren't so funny. I've decided that it's time to stop beating a dead horse. Usually I get paid good money to own software this hard, and I don't think you're worth making an exception. Best of luck, I'm sure you'll figure it out eventually.'
