TOP OF THE NEWS
Attacks on US Federal Networks Increased in 2014 (March 4, 2015)According to a report from the Office of Management and Budget (OMB), there were 70,000 reported cyber security incidents involving federal systems in 2014, a 15 percent increase over the figure for 2013. Some of the increase can be attributed to improved monitoring. Ninety-two percent of federal agencies now have implemented continuous monitoring; last year, the figure was 81 percent. Nearly half of the incidents could have been prevented if strong authentication measures had been implemented.
Law Firms to Launch Threat Data Sharing Forum (March 5, 2015)International law firms will launch a forum to help them share cyber threat information. The system is expected to launch this spring with between six and 12 member firms. The forum is being established as a branch of the Financial Services Information Sharing and Analysis Center and will have access to some of that organization's data as well.
Anthem Refused OPM Audit Scans (March 5, 2015)Anthem refused to allow the US Office of Personnel Management's Office of the Inspector General (OIG) to conduct scans for a security audit after the breach of its systems. Anthem did undergo an audit in September 2013; it refused the scans at that time as well, but allowed a more general audit.
[Editor's Note (Ullrich): There are many reasons to refuse a scan. Most of them are not valid. What companies will have to realize is that an authorized scan conducted by a professional and skilled penetration tester will always be less risky then the scan the bad guys are running on your systems all day. ]

THE REST OF THE WEEK'S NEWS
Detecting Suspicious Domains (March 5, 2015)Technology being developed by OpenDNS aims to hasten detection of malicious websites and domains. The technology, called Natural Language Processing Rank (NLPRank), checks for suspicious site names. To reduce the incidence of false positives, it also checks to see if the domain is running on the same network that the organization it claims to be from actually uses.
[Editor's Note (Northcutt): OpenDNS is a really cool operation and if you are not using it for your home network you should really consider it; this goes double if you are a parent. And NLPRANK is an idea whose time has come. The idea of registering domain names that are similar to valid and trustworthy names e.g. Micr0s0ft.com is not new. What is fairly new is the ability of attackers to prepare an attack, register these slightly-off domains, embed them in tiny urls, phishing links in emails, etc., and mop up the opportunities the people that succumb to the attack present them in a very short period of time. In manufacturing and quality control, people are very sensitive to cycle time. We need to apply that type of mindset in defensive cybersecurity:
Google Updates Chrome to Version 41 (March 5, 2015)Google has promoted Chrome 41 to the stable channel for Windows, Mac, and Linux. The newest version of the browser addresses more than 50 vulnerabilities.
FTC to Look at Cross-Device Tracking (March 5, 2015)The US Federal Trade Commission (FTC) will hold a workshop in the fall to examine cross-device tracking and how it affects consumers. Such events can indicate that the agency will follow up with reports and increased enforcement of privacy rules.
[Editors' Note (Murray/Paller): The FS/ISAC is the poster child for trusted intelligence sharing. It demonstrates that the "immunity from liability" provisions of the pending CISA (
legislation is not necessary for the purpose for which it is proposed. One wonders why it refuses to die? ]
Mandarin Oriental Breach (March 4 & 5, 2015)The Mandarin Oriental hotel chain has confirmed a breach of its systems that compromised customer payment card information. The attack affected point-of-sale systems at 45 of the company's hotels.
[Editor's Note (Murray): One more breach only confirms what we already know. THERE IS NOTHING LEFT TO HIDE. To the extent that our retail payment system relies upon the secrecy of credit card numbers for its security, it is permanently busted. In a world in which hundreds of millions of credit card numbers are known to have been breached and in which credit card numbers sell for dollars in white markets and pennies in black markets, merchants must assume that they are breached, consumers must assume that they are targets, and issuers must assume that a large percentage of charges presented to them are fraudulent. Help is at hand in form of real-time transaction confirmations and tokenization of the card number. Issuers must offer (many already do) near real time transaction confirmations. (Even my little three branch community bank offers this service.) Consumers must demand and opt-in to such notifications and reconcile the notifications that they get. AmEx reports that using such transaction notifications they are detecting fraudulent transactions within sixty seconds. Consumers must prefer proxies, like PayPal, Apple Pay, and the newly announced Samsung Pay and Android Pay (when available), that hide the credit card number from the merchant. Brands must offer and banks must use digital tokenization services like Visa Token Service that substitute a one-time Payment Authorization Number (PAN) for the credit card number. ]
GAO Finds Weaknesses in US Air Traffic Control Systems (March 2 & 4, 2015)A report from the Government Accountability Office (GAO) found that while the Federal Aviation Administration (FAA) has implemented measures to protect its systems from attacks, "a significant number of weaknesses remain in the technical controls - including access controls, change controls, and patch management - that protect the confidentiality, integrity, and availability of its air traffic control systems."
[Editor's Note (Murray): Do not gloat over this report. Rather, pretend that it had been written about you; it might well have been. Be thankful that such reports as are written about you are not reported in the press. ]
D-Link Releasing Firmware Updates (March 4, 2015)D-Link is releasing firmware updates to fix three vulnerabilities in its products that could be exploited remotely. The most concerning of the flaws could be exploited to change DNS settings. Along with the updates, D-Link offered recommendations to improve security, including disabling remote administrative access.
GoDaddy Sites Being Used in Domain Shadowing Attacks (March 4 & 5, 2015)Cyber criminals are using GoDaddy-registered websites to launch attacks. The technique is called domain shadowing, and involves breaking into GoDaddy accounts and setting up fake subdomains from which users are redirected to malicious sites. Domain shadowing allows the attackers to evade detection through blacklisting.
[Editor's Note (Ullrich): We have seen this technique all the way back to 2010 (e.g.
used for spam. If you haven't done so, make sure you setup a system to monitor your DNS zone continuously and completely. It is not sufficient to check for altered NS records, or altered replies for your most common hostnames (www.company.com, mail.company.com). In addition, it is critical to verify that no records were ADDED to your zone. At least check for changes to the zone's serial number, but attackers may not update it as they don't need 100% reliable lookups. ]
Freak Flaw (March 3, 4, & 5, 2015)The FREAK vulnerability affects both the Secure Sockets Layer (SSL) and Transport layer Security (TLS) protocols in Apple's Safari browser, Google's Android browser, and in Windows. It can be exploited to "downgrade ...the cipher suites used in an SSL/TLS connection" and intercept traffic between clients and servers. The issue has its roots in 20-year-old US encryption export restrictions, which saw the weaker algorithms used in products that were exported from the US.
[Editor's Note (Ullrich): Great example of what happens when governments get involved in weakening cryptography to enable surveillance. Microsoft's schannel SSL library is vulnerable as well. On the other hand, this bug isn't quite as critical as many make it appear. At least on the server side, these ciphers have been disabled in default configurations for a long time. No need to panic; patch as patches become available. ]
Washington State Hospital Sues Bank Over Fraudulent ACH Transactions (March 3, 2015)A Washington state hospital (Chelan County Hospital No. 1) is suing Bank of America to recoup more than US $1 million the hospital lost in fraudulent transactions. In April 2013, thieves infiltrated the hospital's payroll account and added phony employees. Then they ran three unauthorized automated clearinghouse (ACH) payroll payments, stealing the funds from the hospital's coffers. Bank of America managed to retrieve US $400,000. The hospital's complaint alleges that someone on the Chelan County Treasurer's staff noticed something was not right and alerted the bank. A bank employee called the office to see whether a pending transfer request was authorized. An employee immediately said that it was not authorized, but the bank still allowed it to be processed.
[Editor's Note (Murray): This report is what the Hospital alleges happened. The value of a trial to us is that its finding of fact is the closest that we will ever come to knowing what really happened. That said, I continue to believe that banks have the fundamental responsibility to ensure that transactions are properly authorized. ]
Correction: Anthem Breach Remedies In the Tuesday, March 3 edition of NewsBites, we incorrectly described remedies Anthem is offering to customers whose data were compromised in the breach. Anthem is automatically providing all affected customers with two years of reactive ID repair; customers may choose to enroll in a proactive ID monitoring service as well. Both are offered at no cost to Anthem customers.
