(InfoWorld) - Hackers are trying to play on business' fear of legal action from customers to trick them into downloading a harmful program distributed through e-mail. The e-mails purport to come from the Better Business Bureau, an organization that monitors and arbitrates disputes between consumers and businesses in the U.S. and Canada. The e-mails assert that a customer lodged a complaint against the recipient's business, according to a warning on the Web site of Websense, a security vendor. The e-mails contain aÂ Microsoft WordÂ attachmentÂ with the text of the supposed complaint and instructions for how to respond. But embedded in that document is a keylogging program that captures data on the victim's computer and then uploads it to a server in Malaysia. The keylogger is purposely mislabeled with a ".pdf" extension -- Portable Document Format -- another widely used document format, to make it look harmless, said Henry Gonzalez, Websense's senior security researcher. The trick is another variation of so-called "social engineering" methods used by hackers, which entice users to unknowingly install harmful programs on their computers. A Better Business Bureau branch warned of a similar kind of attack in February. At that time, the e-mails contained hyperlinks to malicious Web sites. Some kinds of malicious software can be installed on a user's computer merely by viewing a site engineered to exploit a vulnerability within a Web browser. The latest attack, using the Word document as the delivery vehicle for the malicious software, is a tactic hackers are increasingly employing.

In a new post to his blog, Chris Hartjes, spurred on by an article in the latest edition of php|architect magazine (covering protecting your code), has shared a few opinions starting with a certain paragraph near the end.   To start, I will focus on the paragraph above. What I get out of that is that if only your source was closed and hidden from prying eyes, it would not have bugs in it. Which is, of course, total nonsense. Code has bugs because it's open and they feel safer? There are two kinds of bugs: application bugs (which is the code I would write) and system bugs (in this case, bugs that that appear from PHP itself). I'm sorry, but there is nothing I can do if there is a bug in PHP that causes my application to crash except to point this bug out to the people who have the ability to fix it.   He goes on to talk more about how protection like this (the article talks about using the IonCube Encoder) will not stop someone if they're really determine to get at the code underneath the encryption. His only suggestion is to make an application good enough that people wouldn't want to try to steal it as much and would rather pay for their version.   Encode your stuff if you want, but be aware that the minute you choose to do that you are telling your customers "I don't trust you" and I have a hard time understanding a business model that assumes people are going to want to steal the stuff you sell.

(InfoWorld) - Users of online banking sites tend to bypass critical clues that the integrity of those sites may have been compromised, according to the working draft of a study released on Sunday by researchers at Harvard University and the Massachusetts Institute of Technology. The study, which will be formally released in May at the IEEE Symposium on Security and Privacy in Oakland, California, underscores how new technologies and warnings can't completely protect Internet users fromÂ scams such as phishing. It also throws doubt on the effectiveness of site-authentication images, which have been implemented by financial institutions such as Bank of America, Vanguard Group, and ING Bank. The images, selected by the customers, are shown when a bank customer logs in from a different computer than is normally used. The study involved 67 users, with more than 90 percent under 30 years old. Because of varying parameters in the study, not all qualified to be included in the results for each of the three tests. Users were ask to conduct common online banking tasks, although precautions were taken to ensure users weren't put at risk. For the first test, HTTPS indicators -- which show that an encrypted connection is enabled -- were removed from the address bar along with the lock that appears in the bottom right corner of Internet Explorer 6. Although the absence of HTTPS indicators should be a warning, all 67 participants continued with their transactions, the study found. The researchers then conducted a test where the site-authentication image was removed along with the HTTPS indicators. The researchers wrote it is the first empirical investigation into site-authentication images. Only two of 60 people chose not to log in when the image was removed, a key sign that a site may have been tampered with or is a phishing site, the study said. Of users who were actually using their own bank account for the study, 23 of 25 continued to enter their passwords. "We find them [site-authentication images] to be ineffective," the study concludes. In the last test, researchers made it more obvious, this time replacing a password-entry page with a warning page from Internet Explorer 7 Beta 3. The page advises of a problem with the security certificate of the chosen Web site. Despite the warning, 30 of 57 users entered their passwords. The study comes as U.S. banks are beefing up their authentication technologies amid new requirements from federal regulators. In October 2005, the Federal Financial Institutions Examination Council (FFIEC) mandated that U.S. banks implement stronger authentication protections by the end of last year, particularly for high-risk transactions such as sending money to a different person's account. Bank of America uses site-authentication image technology called SiteKey. Users pick an image and assign a phrase to it while also setting three "challenge" questions. If a user logs in from a computer that doesn't already have a cookie, they're asked one of the challenge questions and then to verify the image and phrase. If the image doesn't appear or the phrase is wrong, consumers shouldn't proceed. Bank of America said the image system benefits users since it's free and doesn't involve extra hardware or software.

(InfoWorld) - Computers belonging to the U.S. government, contractors, and companies in the transportation industry were hit by a targeted computer attack in July that yielded password information for hundreds of Internet and intranet Web sites, a computer security vendor said Tuesday. The malicious code behind the attacks was first detected by computer intrusion prevention vendor Prevx on July 5. In total, the criminals were able to cull 200MB ofÂ information from about 500 computers, including password and login data, Prevx said. All but one of the computers was located in the U.S., and many of the computers that were infected were associated with air transportation, according to Mel Morris, CEO of Prevx. "This was a well-coordinated attack by someone wanting to get information on the related sites." PCs at the U.S. Department of Transportation (DOT), American Airlines, and DOT contractor Booz Allen Hamilton all were compromised, Morris said. If DOT systems were compromised, the department is unaware of the situation. "We haven't found any record of a problem," a DOT spokeswoman said Tuesday. Prevx obtained a sample of the Trojan used in the attacks on Friday of last week. By Saturday, it had tracked down a Web site, hosted by YahooÂ in Sunnyvale, California, where information from the compromised PCs was dropped. Because Prevx found a "massive amount" of job applications on the Web site used by the criminals, the company believes that victims may have downloaded the malicious software while thinking they were applying for a job. That Web site, which had probably been hacked by the criminals behind the scam, was shut down on Tuesday, Morris said. It hosted about 200MB of password information, and log-files on the server showed the IP addresses of the infected PCs. Victims of the Trojan, called Win32.PSWSteal.Gen , are told that their hard drive has been encrypted and that they will need to pay $300 to for a decryption tool. Morris believes this extortion threat is actually a ruse designed to conceal the attacker's true motivation: data gathering. "We think the ransomware is to point anyone investigating this down the wrong alley," he said. Morris said he is troubled that such a high percentage of the infected PCs are related to the transportation sector, which has been the target of terrorist attacks. "When we reverse-engineered the IP addresses of those computers, we couldn't believe that this was a daisy chain that led to government-associated sites and to other defense contractors, and to American Airlines," Morris said. "This was a very highly targeted attack." Criminals have increasingly turned to this type of targeted attack in order to collect and eventually sell data from corporations and government agencies, said Marcus Sachs, deputy director of research group SRI International's Computer Science Laboratory. But while Prevx's list of compromised organizations is "kind of scary," it's still hard to characterize what was motivating the attack, Sachs said. "I wouldn't necessarily associate it with terrorists," he said.

Web gateway filtering specialist Finjan is reporting a new toolkit that uses randomized JavaScript to stay hidden from virus crawlers and deliver its payload via compromised Web sites.Dubbed by Finjan's Malicious Code Research Center (MCRC) as the "Random JS Toolkit," the malware development package is allowing attackers to create threats that only attempt to victimize an individual computer in the same manner a single time to protect against discovery by anti-virus systems and researchers' automated "crawlers."By dynamically changing the JavaScript employed to deliver each variant of attack being created, and by using random file names that are only delivered to the same machine or IP address once, Finjan researchers said the malware authoring package is meant to avoid the programs used by AV researchers to find new threats emerging on the Web.Typically when automated crawler programs come across new attack samples, they return to the threats' source URLs to verify their names and characteristics and to create signature files that allow their products to block the programs -- or they enter the sites onto so-called blacklists of compromised domains.However, once a machine has been infected with an attack made using the Random JS Toolkit, the threat will recognize that the machine has already been targeted and won't attempt to download it again, thereby thwarting efforts to identify or track the exploits, Finjan experts contend.During the month of December 2007, Finjan estimates that more than 10,000 individual sites were compromised with attacks built using the Random JS Toolkit. Most of the URLs serving as distribution points for the attacks were legitimate sites that had been hijacked, the company said.Among the infected sites were some that would qualify as well-known, highly trusted domains, said Yuval Ben-Itzhak, chief technology officer of Finjan.Ben-Itzhak said the toolkit serves as a prime example of the types of tactics he expects leading-edge malware authors to utilize more frequently in the coming year."We've found the initial 10,000 sites, but we're sure that there are many more that have already been infected. When we can find this number of exploits, it is clear that this must be a very significant attack that has affected a lot of people," he said. "Using the combination of techniques available in this toolkit, the threats that are being created can become very powerful and stay alive to infect people for longer periods of time."Among the types of malware infections being served up using the toolkit, Finjan has observed everything from Trojan viruses and keystroke loggers to botnet recruiting programs, he said.For its part, Finjan's real-time code inspection technology can defend against such threats because it eschews the use of traditional virus signatures or blacklists in favor of constant monitoring for any malware activity coming across a network armed with one of its devices, Ben-Itzhak maintains.Rival AV vendors, including Symantec, contend that features such as the market leader's recently developed "generic exploit prevention," based on behavioral cues, should also be able to isolate and defend against such emerging attacks.Unlike the widespread iFrame attacks that proliferated across the Web during 2007, threats created using the Random JS Toolkit will also be much harder for security researchers to track down because they do not lead back to central sites where the actual malware code itself is hosted, Finjan maintains.Since the involved malware code is loaded directly on a site, and it won't attempt infect the same computer or IP address twice, traditional URL blacklisting and signature-based techniques will likely prove futile against the attack, the company said.However, from what the security appliance vendor can deduce, Ben-Itzhak said the firm believes there is only one malware group currently using the toolkit."From what we can tell, all the information flowing back from the compromised sites is heading to the same server," he said. "This indicates that there is probably only one group controlling this malware code thus far, and that they are probably being very successful; this is just another step forward for the criminals involved to continue to improve their attack methods and remain undetected."Ben-Itzhak said that the involved server is not one that matches any of the company's lists of machines controlled by well-known malware authoring groups such as the Russian Business Network. The server the company is tracking was originally located in Europe, but has recently been moved to China -- and likely will continue to be moved around to avoid detection, according to the expert.Most of the data the security company has seen being sent to the server has been related to online banking username and password data, he said.As part of its investigation, Finjan discovered that one of the Web properties infected with the randomized JavaScript attacks was an online advertising network that serves up as many as 14 million online banner ads per week. The security device maker reported that unnamed company was informed and is currently working to clean out its systems.

Consider anti-reconnaissance tools Hurwitz &amp; Associates has been running an IT security campaign: "AVID: Anti-Virus Is Dead" for some time. The argument is based on the principle that blacklists of signaturesâsmall files that contain a unique string of bits, or the binary pattern, that identifies all or part of a virusâdo not, and cannot, provide adequate protection against viruses. This is because the signature files can only be written once a virus or other form of malicious software program has been identified. When a new malware program is discovered, the race is on to write a signature file for protecting against that virus. It's like putting a plaster on an open wound, rather than taking care not to get cut in the first place.â¦

(InfoWorld) - A vulnerability in Ask.com's toolbar for Internet Explorer could allow an attacker to take control of a person's computer, according to security advisories. The problem concerns a buffer overflow flaw in the toolbar and involves an ActiveX control, according to an advisory posted by security vendor Secunia APS, which rated the problem as "highly critical," its second most severe rating. It affects version 4.0.2 of the toolbar and possibly others. Proof-of-concept exploit code for the vulnerability has been publicly posted on other disclosure forums, with a person named "Joey Mengele" credited with finding the flaw. Ask.com officials contacted in London were not immediately able to comment. The Ask.com toolbar sits below the address bar and can perform a variety of category-specific searches, such as weather information, stock quotes, or search a person's desktop as well as regular Web searching. As of Tuesday afternoon local time,Â WabiSabi Labi, a Swiss company that specializes in selling vulnerability information, was still auctioning the Ask.com toolbar problem for minimum of â¬500 ($705), although no bids were listed. WabiSabi Labi's auctioning of security vulnerabilities has caused a stir among security analysts who believe software companies should be discreetly notified of vulnerabilities and allowed to patch the software so as to not put users in danger. The company maintains security researchers should be rewarded for their work.
