Flash: A logic bomb appears to have triggered multiple outages in South
Korea simultaneously and may have had a very short fuse. This is the
union of the Saudi Aramco attack (causing large scale damage requiring
physical action to repair EACH machine) and attacks against banks, and
it is aimed at a U.S. ally, hinting (but only hinting) at the source.
SAP, the business management software from Oracle, may be an
increasingly popular target of cyber attacks. We are considering adding
an intensive course on security for SAP, but won't do it unless there
is significant demand. If you believe your organization would send
people to such a course (2 days at the front or back of a SANS training
conference), send email (no commitment needed) to SAP@SANS.org.

TOP OF THE NEWS
Major Cyberattack Hits South Korean Banks and Broadcasters (March 20 & 21, 2013)A major cyberattack hit South Korean banks and broadcasters earlier this week. Two of the country's large banks and three broadcasters were affected, but government systems were not targeted. The malware wiped files from infected computers. Shortly after the attacks, there was speculation that North Korea was responsible, but there has not been positive attribution. James Barnett, former chief of public safety and homeland security for the US Federal Communications Commission (FCC) notes that, "This needs to be a wake-up call. This can happen anywhere." Investigators think that malware may have been spread through servers that send out automatic updates and patches. Symantec researchers say the attack used a Trojan horse program known as Jokra, which can overwrite computers' master boot records and all the data stored there.
[Editor's Note (Honan): There are a lot of lessons to be learnt from this incident, not least that attribution is hard. Initial analysis had Korean officials claiming the attacks came from an IP address in China thus focusing the blame on that country. However, further investigation shows " the IP address that was thought to be from China was determined to be an internal IP address from one of the banks that was infected by the malicious code " Given the recent rhetoric about striking back with both cyber and kinetic weapons let's hope this demonstrates we cannot rely on IP addresses alone for identifying and blaming an attack on someone and more measured responses are required. More details at
(Assante): Data erasing overwrites are not new but their use never made much sense as information had value for the attacker. The recent use of these destructive attacks, in scale, demonstrates that cyber has become a political means to send pointed messages and cause harm. There are those willing to loudly assert that they can hold economies and infrastructures at risk. Our response should be simple..."we are not afraid", as we have the practices and technology necessary to blunt these types of attacks. ]
US Government to Broaden Scope of Internet Traffic Scanning (March 21, 2013)The presidential executive order on cybersecurity issued in February calls for increased scanning of Internet traffic. The scans will be based on classified information provided by US intelligence agencies about emerging and serious cyber espionage and cyber attack threats.
Cyber Command Will Deploy More than 100 Cyberdefense Teams by End of 2015 (March 19 & 21, 2013)The US Defense Department's Cyber Command plans to deploy more than 100 military cyberdefense teams by the end of 2015. Most of these teams will focus on protecting military networks, not on attacking systems of adversaries. General Keith Alexander, head of Cyber Command, said last week that by September 2013, 13 cyberwarrior teams will be deployed. These teams will focus on taking action against adversaries' networks to prevent attacks on US critical infrastructure systems.
TeamSpy Cyberespionage Campaign a Decade Old (March 21, 2013)Researchers say they have found evidence of a cyber espionage campaign targeting Eastern Europe and the former Soviet Union, that has been going on for 10 years. The cyberspies installed TeamViewer, a tool usually used to control computers remotely and conduct online meetings, on targeted computers and altered its code to create a backdoor on the systems. Researchers have dubbed the campaign TeamSpy. The group's targets appear to be governments, businesses, and human rights activists. Those behind TeamSpy gathered encryption keys and secret documents.

Microsoft Discloses Law Enforcement Data Requests and Number of NSLs Received (March 21, 2013)Microsoft has joined Google and Twitter's move toward increased transparency by disclosing data about law enforcement requests for user information. In 2012, Microsoft received 75,378 requests for customer information related to 137,424 accounts or other identifiers. In just over two percent of the requests, Microsoft provided law enforcement agents with content, such as email or photos. In 99 percent of those cases, the recipients of the content were US law enforcement agencies with warrants. In more than 56,000 cases, Microsoft provided non-content data, including user names, email addresses, IP addresses and countries of residence. The majority of the data were provided to law enforcement agencies in the US, the UK, Turkey, Germany, and France. Microsoft has also disclosed ranges of numbers of National Security Letters (NSLs) is has received, along with a range of numbers of identifiers those NSLs covered.
London Police Arrest man in Connection with Online Banking Trojan (March 19 & 21, 2013)Police in London, UK have arrested a man in connection with the Tilon Trojan horse program. The malware was used to conduct bank fraud. Tilon is man-in-the-browser malware, which intercepts information entered on web pages in Internet Explorer, Firefox, Chrome, and possibly other browsers as well. Tilon was designed with detection evasion in mind: it will not install on a virtual machine.
Matthew Keys Denies Giving Hackers Login Credentials for Tribune Servers (March 21, 2013)Matthew Keys, the former Tribune Company employee who was accused of helping hackers gain access to that company's servers, has denied that he gave anyone login credentials. Keys posted a statement to his Facebook page that says, in part, that he "did not 'conspire' to 'cause damage to a protected computer' ...
cause 'transmission of malicious code.'" The intruders altered the headlines and byline of one article. Keys's arraignment is scheduled for April 12.
Weak Password Hash Algorithm Implementation in Some Cisco Devices (March 20 & 21, 2013)A weak implementation of a password-hashing algorithm in Cisco's IOS operating system version 15 makes passwords significantly more vulnerable to brute force hacking. The algorithm was supposed to have an 80-bit salt value and use 1,000 iterations through SHA256, but instead, the password is not salted at all and undergoes just one SHA256 iteration. The new algorithm is called Type 4 and was intended to be stronger that the Type 5 and Type 7 algorithms.
Microsoft Says High-Profile Xbox Live Accounts Compromised (March 20, 2013)Microsoft said that hackers used social engineering tricks to take over high-profile Xbox live accounts. The accounts that were taken over belong to current and former Microsoft employees. The account hijackings appear to be related to a recent story by security journalist Brian Krebs about a website that sells access to credit reports, driver's license numbers, and Social Security numbers (SSNs). The Xbox hackers used that site to obtain information that they used in their social engineering attacks. Krebs was recently targeted in a SWATting attack: hackers placed an emergency call that appeared to come from Krebs's phone and reported a dangerous situation. The individual alleged to be behind the attack also arranged for Krebs's website to be hit with a denial-of-service attack earlier that same day.
House Committee Passes Bill That Would Give Federal CIOs Budget Authority (March 20, 2013)In a unanimous vote, the US House Oversight and Government Reform Committee has passed the Federal Information Technology Acquisition Reform Act, which would give agency CIOs the authority to move funding from one technology project to another. Currently, the Department of Veterans Affairs is the only agency at which the CIO has such authority. The bill also stipulates that each agency would have only one CIO, and it would make federal agency CIOs presidential appointees. The bill now goes before the full House for consideration.
Senators Introduce Bill to Amend ECPA (March 20, 2013)Two US senators have introduced legislation to amend the 1986 Electronic Communications Privacy Act (ECPA), which they say is outdated. The lawmakers want to require law enforcement to obtain warrants before examining citizens' electronic communications. ECPA allows authorities to obtain email that is more than 180 days old with a subpoena. One of the bill's sponsors, Senator Patrick Leahy (D-Vermont), said in a statement, "Privacy laws written in an analog era are no longer suited for privacy threats we face in a digital world."
[Editor's Comment (Northcutt): Outdated? It was only passed in 1986 (grin); I love what I am hearing about requiring warrants, but as it gets closer to passing I bet we start to hear about terrorists and the need to keep removing rights from US Citizens. But here is hoping, I will be keeping a close eye on the EPIC and EFF websites devoted to the topic:
Adware Trojan Targets OS X Systems (March 20, 2013)The Yontoo Trojan horse program installs a plug-in that displays fraudulent advertisements on web pages. Yontoo targets computers running Mac OS X. It spreads by disguising itself as a media player, a video quality enhancement tool, and a download accelerator. The installer asks users if they want to install an app called Free Twit Tube. If users click yes, the Trojan is downloaded onto their computers and the malware monitors their web browsing and through a remote server, injects the ads onto the sites they visit. Yontoo is being classified as a Trojan because it uses trickery and disguises to become installed.
[Editor's Note (Frantzen): Original source is the Russian anti-virus company Dr. Web:
FBI Arrests Chinese National US Military Contractor as he Tries to Leave Country (March 19, 2013)On March 16, a Chinese national who is a military contractor was arrested on an airplane as he tried to leave the country. Bo Jiang worked at NASA-Langley in Virginia. An FBI affidavit says that Jiang is being investigated for "substantive violations of the Arms Control Act." Whistleblowers at Jiang's workplace informed the FBI that he planned to leave the country with a one-way ticket. The affidavit also states that Jiang is believed to have left the US previously with a laptop computer that contained sensitive information. Federal agents boarded the airplane that Jiang was on and questioned him about what electronic devices he was taking with him. He did not disclose all electronic media he was traveling with to federal agents. He has been charged with lying to federal agents.
Miami-Dade County Department of Elections Targeted in Absentee Ballot Request Fraud (March 18, 2013)According to a grand jury report, a hacker or hackers managed to "create a computer program that automatically, systematically, and rapidly submitted" online requests for absentee ballots to the Miami-Dade County (Florida) Department of Elections. In all, the scam made more than 2,500 fraudulent requests over the course of two-and-a-half weeks. A vendor saw the requests coming from the same group of computers and at a rate that would be impossible for humans to enter the information required. The requests were flagged and the ballots requested were not sent out. The grand jury report is from December 2012 and the Miami herald reported the story in February. The attack did not require any sophisticated skills.
