Social Media Biggest Risk in 2012

Social Media Biggest Risk in 2012The Security Labs over at Websense (WBSN) a provider of Web, data, and email content security have used the Websense ThreatSeeker Network (PDF) which provides real-time reputation analysis, behavioral analysis, and real data identification to announce (PDF) their picks for the top IT security threats for 2012. Social media is the #1 risk in 2012,.

1. Websense says that stealing, buying, trading credit card, and social security numbers is old news. They say that your social media identity may prove more valuable to cybercriminals than your credit cards.

LinkedIn connections for saleToday, your social identity may have greater value to the bad guys because Facebook (FB) has more than 800 million active users. More than half of FB users log on daily and they have an average of 130 friends. Trust is the basis of social networking, so if a bad guy compromises social media logins, the security firm says there is a good chance they can manipulate your friends. (Stacy Cowley at CNN Money has an excellent article on how this can work with LinkedIn (LNKD). Which leads to their second prediction.

2. According to Websense most 2012 advanced attacks’ primary attack vector will blend social media “friends,” mobile devices, and the cloud. In the past, advanced persistent threats (APTs) blended email and web attacks together. In 2012, the researchers believe advanced attacks could use emerging technologies like: social media, cloud platforms, and mobile. They warn that blended attacks will be the primary vector in most persistent and advanced attacks of 2012.

iPad malware3. The San Diego CA-based firm says to expect increases in exposed vulnerabilities for mobile devices in 2012. They predict more than 1,000 different variants of exploits, malicious applications, and botnets will attack smartphones or tablets. Websense security investigators predict that a new variant of malware for mobile devices will appear every day.

The Internet security firm stresses that application creators need to protectively sandbox their apps. Without sandbox technology malware will be able to get access to banking and social credentials as well as other data on the mobile device. This includes work documents and any cloud applications on that handy device. The firm believes that social engineering designed to specifically lure mobile users to infected apps and websites will increase. Websense predicts the number of mobile device users that will fall victim to social engineering scams will explode when attackers start to use mobile location-based services to design hyper-specific geolocation social engineering attempts.

SSL/TLS blindspot4. SSL/TLS will put net traffic into a corporate IT blind spot. Two items are increasing traffic over SSL/TLS secure tunnels for privacy and protection. First, the disruptive growth of mobile and tablet devices is moving packaged software to the cloud and distributing data to new locations.

Second, many of the largest, most commonly used websites, like Google (GOOG) Search, Facebook, and Twitter have switched their sites to default to HTTPS sessions. This may seem like a positive since it encrypts the communications between the computer and destination. But as more traffic moves through encrypted tunnels, Websense correctly says that many traditional enterprise security defenses (like firewalls, IDS/IDP, network AV, and passive monitoring) will be left looking for a threat needle in a haystack, since they cannot inspect the encoded traffic. These blind spots offer a big doorway for cybercriminals to walk through. (We have started to battle this as we move from a POC system from McAfee another vendor to a modem content filter to be nameless but was just bought and we haven’t solved it yet, the NoSSLSearch for GOOG still needs some work)

Network security5. For years, security defenses have focused on keeping cybercrime and malware out (Also called M&M security, hard on the outside, soft and chewy on the inside). The Websense Security Lab team says that there’s been much less attention on watching outbound traffic for data theft and evasive command and control communications. The researchers say hacking and malware are related to most data theft; they estimate that more than 50 percent of data loss incidents happen over the web. This is aggravated by delayed DLP deployments as vendors use traditional overly excessive processes like data discovery (designed to over-sell professional services?).

In 2012, organizations will have to stop data theft at corporate gateways that detect custom encryption, geolocations for web destinations, and command and control communications.  The security firm predicts organizations on the leading edge will add outbound inspection and will focus on adapting prevention technologies to be more about containment, severing communications, and data loss mitigation after an initial infection.

Black-Hat-SEO_full6. The London Olympics, U.S. presidential elections and Mayan calendar apocalyptic predictions will lead to broad attacks by criminals. SEO poisoning has become an everyday occurrence. The Websense Security Labs still sees highly popular search terms deliver a quarter of the first page of results as poisoned.

The researchers expect that as the search engines have become savvier on removing poisoned results, criminals will port the same techniques to new platforms in 2012. They will continue to take advantage of today’s 24-hour, up-to-the-minute news cycle, only now they will infect users where they are less suspicious: Twitter feeds, Facebook posts/emails, LinkedIn updates, YouTube video comments, and forum conversations. Websense recommends extreme caution with searches, wall posts, forum discussions, and tweets dealing with the topics listed above, as well as any celebrity death or other surprising news from the U.S. presidential campaign.

Scareware7. Scareware tactics and the use of rogue anti-virus, will stage a comeback. With easy to acquire malicious tool kits, designed to cause massive exploitation and compromise of websites, rogue application crimeware will reemerge Websense says. Except, instead of seeing “You have been infected” pages, they expect three areas will emerge as growing scareware subcategories in 2012: a growth in fake registry clean-up, fake speed improvement software, and fake back-up software mimicking popular personal cloud backup systems. Also, expect that the use of polymorphic code and IP lookup will continue to be built into each of these tactics to bypass blacklisting and hashing detection by security vendors. (Rival IT Security firm GFI Software proves Websense’s point by reporting a “new wave of fake antivirus applications (or rogue AV)” since the start of the year and are “a popular tactic among cybercriminals.”)

LinkedIn Accounts can be Hijacked

Help Net Security has a report that users of the newly minted public LinkedIn (LNKD) are in danger of having their account hijacked. The Linkedin accounts can be hacked when accessing them over insecure Wi-Fi networks or public computers. Independent security researcher Rishi Narang told Help Net Security that the risk is due to two reasons. First, the LinkedIn session and authentication cookies have an unnaturally long lifespan. Secondly, LinkedIn does not remove the cookies once the user logs out.

LinkedInThe article says the cookies in question are JSESSIONID and LEO_AUTH_TOKEN, and are available even after the session initiated by the user has been terminated. The cookies are also set to expire only after one solid year, and this fact allowed the researcher to get access to a number of active accounts of various people from all over the world during a period of many months. “They would have login/logged out many times in these months but their cookie was still valid,” Mr.Narnag writes on his blog.

In addition to all of that, those two cookies and the others that the welcome page stores are transmitted in clear text over HTTP, because they don’t have a secure flag set. “If the secure flag is set on a cookie, then browsers will not submit the cookie in any requests that use an unencrypted HTTP connection, thereby preventing the cookie from being trivially intercepted by an attacker monitoring network traffic,” explains Mr. Narang.

According to the researcher, until LinkedIn makes some changes, the only way to “expire” the cookies is for the users to change their password and then authenticate themselves with the new credentials. This could be a stopgap measure if you know that someone has stolen those cookies and is accessing your account, but won’t new cookies be created after the password change and authentication?

Help Net Security says that the only solution to this problem is for LinkedIn to effect some changes, and according to Reuters, they are planning to offer “opt-in” SSL support for the entire site in the coming months (and that would encrypt the cookies in questions), but have not commented on the cookies have such a long lifespan.

Feds Aim to Nationalize Private Networks

Feds Aim to Nationalize Private NetworksIn the tradition of federalization of the auto industry. And in keeping with promises made in the 2008 campaign. The Obama administration and Democrats in Congress are proposing to increase cybersecurity by federalizing networks. The legislation, co-sponsored by Senate Commerce Committee Chairman John D.”The Internet Should Never Have Existed” Rockefeller IV (D-W.Va.) and Sen. Olympia J. Snowe (R-Maine), was drafted with White House input.

Office of the National Cybersecurity AdviserThe Rockefeller-Snowe measure would create the Office of the National Cybersecurity Advisor, the White House cybersecurity “czar.” The czar would report directly to the president and would coordinate defense efforts across government agencies. The proposed bills go beyond securing government networks and puts the White House in charge of the security of private networks with the authority to shut them down. Under the guise of “critical infrastructure”, the Feds are going to nationalize banking, utilities, air/rail/auto traffic control, and telecommunications networks.

The new rules are proposed in two senate bills, S.773 the Cybersecurity Act of 2009, and S.778. S.778 is a bill to establish, within the Executive Office of the President, the Office of National Cybersecurity Advisor. S.773 is “A bill to ensure the continued free flow of commerce within the United States and with its global trading partners through secure cyber communications, to provide for the continued development and exploitation of the Internet and intranet communications for such purposes, to provide for the development of a cadre of information technology specialists to improve and maintain effective cybersecurity defenses against disruption, and for other purposes.”

NIST logoIt would require the National Institute of Standards and Technology to establish “measurable and auditable cybersecurity standards” that would apply to private companies as well as the government. It also would require licensing and certification of cybersecurity professionals.

Director of National Intelligence Dennis C. Blair acknowledged there will be privacy concerns about centralizing cybersecurity, and he told the Washington Post that the program should be designed in a way that gives Americans confidence that it is “not being used to gather private information.”

How does the Obama Cyber Czar plan to ensure the continued free flow of commerce when they take the Telco networks off-line. In case they haven’t noticed, the telcos provide most of the long-haul interconnect for the Internet. If the Obama Cyber Czar decides to take the banks offline, there are going to be bigger problems. Can you say bank run? I will pull my cash out at the local branch.

Finally, this is a bad policy, because the Security Czar is a political appointment and network security is too important to be left to politics unless of course, it is in the corporate boardroom.
