  • Shady Rat

    On Tuesday (Aug 2 2011) the security firm McAfee released a report on "Operation Shady Rat". McAfee describes an operation that has been ongoing since 2006, which has infected 72 U.S. and foreign government agencies, defense contractors and international organizations (such as the U.N., the U.S. International Trade Organization and the World Anti-Doping Agency, but most organizations were not named by McAfee). McAfee says that it was "surprised by the enormous diversity of the victim organizations". The general news media has seized on the event and claimed that it is an "unprecedented" attack of epic proportions. Yet as more information is gleaned it may be that Shady Rat was not all that uncommon. What's missing in the McAfee report is any hard data on what may have been stolen, which organizations were the victims of attacks, and how many computers were involved. Without that data the claims that it is one of the "most sophisticated attacks in history"...
  • Apple Patches Serious 2002 Vulnerability For Some Devices

    A vulnerability that dates back nine years was patched by Apple on Monday (Jul 25 2011). Apple devices that use the iOS operating system (such as iPhone 4 and 3GS along with the third and fourth generation iPod Touch) are vulnerable to an attacker who can intercept and then decrypt secure SSL communications {Chapter 12 Security+ 3ed} using a man-in-the-middle attack {Chapter 4 Security+ 3ed}. The updated attack tool "sslsniff" can be used to easily view user information. Some security experts are stating that this latest attack is more serious than Firesheep (see Oct 27, Nov 3 and Nov 11 2010 blog postings). This same vulnerability was also in Microsoft Windows yet it was patched back in 2002. A Windows user will receive the warning of an "Invalid Certificate" in a browser as a warning. A patch is now available from Apple to fix this vulnerability. Unfortunately, users with an original iPhone, iPhone 3G, or first- or second-generation iPod Touch cannot patch their devices...
  • Rustock Reward

    Need some extra pocket money to finish out your summer plans? Well, here's your chance--and in the process you can help reduce worldwide spam. Ever since the Rustock botnet {Chapter 2 Security+ 3ed} was crippled by Microsoft and others using the courts instead of technology (see Mar 19 2011 blog) the amount of spam coming from its zombies has decreased significantly. Yet because there are still hundreds of thousands of Rustock zombies {Chapter 2 Security+ 3ed} still out there, Microsoft has decided to keep the pressure on. In June Microsoft published notices in two Russian newspapers to service as notice to the individuals behind Rustock of the civil lawsuit that has been filed against them. And on Monday (Jul 18 2011) Microsoft maee an even bolder move. They are now offering a quarter of a million dollars for new information that results in the identification, arrest and criminal conviction of the Rustock operators. Microsoft says that "residents of any country are eligible for...
  • Shocking Attacks Through Wireless LAN

    One of the most shocking attacks using a wireless network has finally come to an end, with the perpetrator being sentenced last Tuesday (Jul 12 2011). Was it a corporate wireless network attack that had company secrets stolen? Was it a breach that allowed attackers to steal credit card information from customers and use it, like the famous TJX heist (see Jun 24 2009 and Feb 8 2010 blog postings)? No, it was none of these. Instead, it was one neighbor attacking another neighbor. In 2009 a couple moved into a new house in Minnesota. The next day their four-year old son wandered into "Barry's" yard, a neighbor. When Barry returned the child to his house he gave the boy a kiss on the lips. This shocked and frightened the couple, so they filed a police report. Barry then decided to take revenge. Barry downloaded wireless attack software as well as purchased books on cracking wireless networks and soon cracked the couple's wireless Wired Equivalent Privacy (WEP) {Chapter 6 Security...
  • Windows Bluetooth Vulnerability Patched

    On Tuesday (Jul 12 2011) Microsoft's July Patch Tuesday {Chapter 4 Security+ 3ed} addressed 22 Windows and Office vulnerabilities. One of these was a Bluetooth vulerability in Windows 7 and Vista devices (Windows XP is not affected because it uses an older Bluetooth implementation). Bluetooth {Chapter 4 Security+ 3ed}, although originally designed as a way to replace wires with radio-based technology, has become very popular for connecting wireless keyboards and mice to computers, particularly laptops. This latest vulnerability (based on a memory corruption) could allow an attacker to establish a Bluetooth connection with a computer and transmit malicious data, allowing the attacker to gain access to the system. And this could occur before the user was notified that another computer requested a Bluetooth connection. This means that an attacker in a coffee shop 30 feet (10 meters) away from your computer could launch an attack before you could react. To protect yourself install the Microsoft...
  • Gmail Phishing Protection

    Google recently updated its Gmail product to provide additional information that may protect against phishing {Chapter 14 Security+ 3ed}. Gmail now automatically displays more information about the origin of e-mail messages so users can make informed decisions regarding the sender's identity and decide if the message is from a legitimate source. When Gmail users receive a message from a sender who is not already listed in their Gmail contacts then the header displays both the sender’s and their full e-mail address. For example, the message would appear as "John Doe - john@x.com". If the e-mail was sent on behalf of a third party, then that is also displayed as "John Doe - john@x.com via hotmail.com". In addition, if Gmail considers the message to be potentially threatening it will display the warning, "This message may not have been sent by:".

  • Preinstalled Malware

    Anyone who has purchased a new computer in the last 20 years has faced the same annoyance: tons of preinstalled software that comes with the system. Most users find themselves spending the first few hours with their new computer deleting this software (or even reformatting the hard drive to install a clean version of the operating system). Now even more devices come preinstalled with something even worse: malware. At a hearing in the U.S. Congress last week, an official with the Department of Homeland Security (DHS) acknowledged that there is a persistent threat of pre-existent malware on computers and other electronic devices imported and sold in the U.S. The problem is that the supply chain for electronic equipment has many stops (product development, manufacturing, assembly, etc.) with numerous middlemen all touching the equipment in locations around the globe. Protecting the security of a device as it moves through the chain is extremely difficult. And it does not include just computer...
  • Office XP and Vista SP1 Support Update

    If you're a user of older Microsoft products, next Tuesday (Jul 12 2011) support for Microsoft Office XP and Windows Vista Service Pack 1 (SP1) is being changed. For Vista SP1 Microsoft will no longer provide public patches {Chapter 3 Security+ 3ed}, including security updates. This means that any automatic updates that normally are available each month on Patch Tuesday will be discontinued. Office XP, which has not received security updates for the past 5 years, will have all support dropped (however, the software will continue to work OK and new installations can still be activated). As a policy Microsoft supports its business products for 10 years: Years 1-5 are "mainstream support" and Years 6-10 are "extended support." Extended support means that any non-security fixes are provided only to companies that have paid for special support contracts. For Office XP it is ten years old and is moving out of extended support, while Vista SP1 is moving into extended support...
  • 50 Days of LulzSec Hactivism Now Over

    The most intriguing security event in 2011 (so far) has been the emergence of a coordinated series of attacks against major large enterprises and government agencies by LulzSec. This may herald a major change in the types of attackers to expect in the future. The backstory from what we know is this: Lulz (a play on LOL or laugh out loud) Security (aka LulzSec) appears to be a small (6 person) group that split off from the larger group Anonymous. Many security researchers believe that Lulz is comprised of highly skilled programmers and creative multimedia artists. Similar (but not identical) to cyberterrorists {Chapter 1 Security+ 3ed}, their claimed ideology is, "We do things just because we find it entertaining." Yet in reality it's not "entertainment". LulzSec's attacks ranged from successfully attacking Sony several times (in retaliation for Sony suing a person for reprogramming his PlayStation 3 gaming console), PBS (for airing a documentary they considered...
  • Apple Patches 36 Security Vulnerabilities

    This past Thursday (Jun 23 2011) Apple released patches {Chapter 3 Security+ 3ed} for its Mac OS X Snow Leopard operating system that fixed 36 security vulnerabilities. In this update Apple pushed out 12 more MacDefender signatures to protect against "scareware" fake antivirus warnings (see May 23 2011 blog posting). Another fix was for the Mac OS X font renderer to the open-source database MySQL that comes bundled with the server versions of Leopard and Snow Leopard. Interestingly, Oracle (who purchased MySQL three years ago) had patched these MySQL vulnerabilities back in February. The size of the Apple patches range from 256MB and 474MB. Apple also distributed security patches for Leopard (Mac OS X 10.5) to address 13 security vulnerabilities. These latest patches follow the March update that addressed 55 vulnerabilities. Apple owners will want to be sure that they apply these updates for two reasons. First, obviously to stay secure. Second, they must be applied before the...

  • Firefox To Enterprises: We're Not Friends

    How long after software is retired should the developer continue to patch {Chapter 3 Security+ 3ed} it by fixing security vulnerabilities? Microsoft, for example, provides security support for at least 10 years after their software is retired or replaced with a newer version. Yet a decision by Mozilla this week to drop support for its just-retired Firefox 4 has many enterprise users upset. And Mozilla says that's just too bad. Mozilla is releasing new editions of Firefox about every six weeks. The latest version, Firefox 5, was released on Tuesday (Jun 21 2011). Yet Mozilla is dropping any security updates to the previous version Firefox 4 (which has only been out for 3 months) effective immediately. For home users it can be an inconvenience to update that often. Yet for enterprises it can result in much more serious problems. IBM, for example, adopted Firefox as its default browser one year ago and currently has half a million users on Firefox 3.6. They have just completed testing...

  • Rampant Password Reuse

    "Rampant (Adjective) - Profuse, unbounded, widespread, everywhere, epidemic, prevalent, unrestrained, unchecked, running wild, uninhibited, wild, uncontrolled, predominant". These are some of the synonyms for the word "rampant". That may be a good word to use in regard to the latest information data about password reuse. The group LulzSec may be responsible for stealing from Sony the user information of over 100 million accounts. As has been the recent practice of other attackers, they then posted this information online. There have already been reports of this information being used to attack Sony customers (such as attackers purchasing equipment online and then charging it to the user's exposed credit card number). Yet this now-public information has also been analyzed by security researchers, as occured when Imperva analyzed 32 million passwords stolen from RockYou (see Jan 28 2010 blog) and Duo Security looked at 1.3 million passwords stolen from Gawker Media...
  • No AutoRun Is Working

    USB flash drives have long been a vector by which attackers spread their malware {Chapter 1 Security+ 3ed}. Panda Software has reported that 1 out of every 4 worms were designed to replicate through USB flash drives, and this is in line with other data regarding how attacks are spread through USB flash drives (see Dec 7 2010 blog). One of the means that made this so easy was Microsoft Window's AuoRun feature. When you inserted a USB flash drive into an older version of Microsoft Windows XP or Vista the "AutoPlay" dialog box appeared with a list of standard choices ("Open folder to view files", "Speed up my system", etc.) that you could launch with a click of the mouse. And if you had an application on that device you would see the AutoRun option "Install or run program". Attackers crafted malware that displayed an option on the AutoPlay menu that looked similar to the normal "Open folder to view files", with the same yellow icon of a...

  • More Adobe Patches

    Security experts have warned for some time now that as the process for patching operating systems {Chapter 3 Security+ 3ed} has become more mature, attackers will focus more of their attention to applications instead. If there's any doubt about that prediction, just look at Adobe, which is struggling to keep its Flash, Reader and other products secure. Yesterday (Jun 14 2011) Adobe issued an "out-of-band" (not in their normal update cycle) patch for their Flash player. A "critical" vulnerability that attackers were already taking advantage of was plugged. This follows another out-of-band critical vulnerability that was patched nine days ago on June 5. If you are keeping count, Adobe has patched its Flash Player four times in the last two months for a total of six times in 2011 (so far). And the sad news doesn't end there. Adobe also patched 13 new vulnerabilities in its Reader product, and all but two of these were called "critical" by Adobe. Yet unlike...

  • Severe Token Damage

    You may recall that RSA, who sells SecureID tokens {Chapter 8 Security+ 3ed} that generate time-synchronized one-time passwords (OTP), revealed back in March that it was the victim of an attack (see Mar 30 2011 blog). Yet at the time RSA only said that that attack occurred "recently" and "certain information" was stolen. Now it appears that the damage resulting from the successful attack is very severe. Last month the government contractor Lockheed Martin was attacked as a result of the RSA security breach. It appears that attackers who broke into RSA stole the "seed" numbers that are used to generate values on RSA's SecurID tokens and then used them to successfully attack Lockheed Martin. Although this caused the company to pull the plug on its virtual private network {Chapter 8 Security+ 3ed} Lockheed says that no customer, employee, or program data was lost. Last week RSA announced that it will replace all SecurID tokens for any customer that makes a...
