Open proxy servers |
|||||||||||||||||||||||||||||||||||||||||||||||||
Any proxy server that doesn't restrict its client base to its own set of clients and allows any other client to connect to it is known as an open proxy server. An open proxy server will accept client connections from any IP address and make connections to any Internet resource. CERT -In tracked 226 open proxy servers functioning in India during January 2010. All the concerned ISPs were alerted immediately to shut down the open proxy servers. A bar chart of open proxy servers tracked during this year is shown in the figure.

| Attack Trend | |||||||||||||||||||||||||||||||||||||||||||||||||
CERT-In has observed that commonly used programs such as Adobe PDF Reader ,Adobe Flash and Microsoft office are exploited widely to steal data from the target computers and also to install back doors through which the attackers can gain control for further exploitations. Most of the times this is happened when users visit infected websites. The infected machines are further used as a medium to propagate the infection to other internal computers. By exploiting vulnerabilities such as SQL injection and XSS flaws, trusted websites are converted to malicious websites serving content that contains client side exploits. |

IE Windows vuln coughs up local files If you use any version of Internet Explorer to surf Twitter or other Web 2.0 sites, Jorge Luis Alvarez Medina can probably read the entire contents of your primary hard drive. The security consultant at Core Security said his attack works by clicking on a single link that exploits a chain of weaknesses in IE and Windows. Once an IE user visits the booby-trapped site, the webmaster has complete access to the machine's C drive, including files, authentication cookies - even empty hashes of passwords. This isn't the first time security researchers at Core have identified security weaknesses in IE. The company issued this advisory in 2008 and this one in 2009, each identifying specific links in the chain that could potentially be abused by an attacker. 768-bit RSA cracked, 1024-bit safe (for now) With the increasing computing power available to even casual users, the security-conscious have had to move on to increasingly robust encryption, lest they find their information vulnerable to brute-force attacks. The latest milestone to fall is 768-bit RSA; in a paper posted on a cryptography preprint server, academic researchers have now announced that they factored one of these keys in early December. Most modern cryptography relies on single large numbers that are the product of two primes. If you know the numbers, it's relatively easy to encrypt and decrypt data; if you don't, finding the numbers by brute force is a big computational challenge. But this challenge gets easier every year as processor speed and efficiency increase, making "secure" a bit of a moving target. The paper describes how the process was done with commodity hardware, albeit lots of it. Google, Adobe attacked through China Google announced that the Internet giant is considering exiting the Chinese market after sophisticated online attacks targeted its systems to breach the Gmail accounts of pro-democracy activists. In a post to its blog , the company stated that an investigation into an attack against the Gmail accounts of pro-democracy activists turned up evidence of a much broader assault against Google's systems. The attack -- first noticed in mid-December and considered "highly sophisticated and targeted" -- resulted in the "theft of intellectual property," the company stated. It's unclear from the statement whether the two Gmail accounts accessed by attackers constituted intellectual property. As a result of the investigation's conclusions, Google intends to stop filtering its results in the Chinese market and open up a debate with the government to discuss its business, David Drummond, chief legal officer for Google, said in the blog post. Firefox-based attack wreaks havoc on IRC users Underscoring a little-known web vulnerability, hackers are exploiting a weakness in the Mozilla Firefox browser to wreak havoc on Freenode and other networks that cater to users of internet relay chat. Using a piece of javascript embedded into a web link, the hackers force users of the open-source browser to join IRC networks and flood channels with diatribes that include the same internet address. As IRC users with Firefox follow the link, their browsers are also forced to spam the channels, giving the attack a viral quality that has caused major disruptions for almost a month. Amateur goof makes Twitter account hijacking a snap Twitter is sitting on an amateur configuration blunder that makes it trivial for attackers to take control of user accounts, a researcher said . The error resides in an Adobe Flash object hosted on the microblogging site, said Mike Bailey, a senior security analyst with penetration testing firm Foreground Security. Contrary to Adobe recommendations, the object is free to load files hosted virtually anywhere on the net, including those containing booby-trapped javascript and action script. "This is not Adobe's fault," Bailey told El Reg . "This is due to the fact that a lot of really bad programmers are coding Flash objects. I've seen literally hundreds of these things across the web." Tor Project suffers hack attack Tor project lead Roger Dingledine confirmed the hack in an e-mail that urged users to immediately upgrade to get fresh identity keys for the two compromised directory authorities. Dingledine writes: We took the services offline as soon as we learned of the breach. It appears the attackers didn't realize what they broke into — just that they had found some servers with lots of bandwidth. The attackers set up some ssh keys and proceeded to use the three servers for launching other attacks. We've done some preliminary comparisons, and it looks like git and svn were not touched in any way. Microsoft knew of IE zero-day flaw since last September Microsoft admitted it knew of the Internet Explorer flaw used in the attacks against Google and Adobe since September last year. The flaw was in the Microsoft Security Response Center's (MSRC) queue to be fixed in the the next batch of patches due in February but the targeted zero-day attacks against U.S. companies forced the company to release an emergency, out-of-band IE update. The IE update applies to all versions of the browser on all Windows OS versions and patches at least eight documented vulnerabilities that could lead to remote code execution attacks. Banking Trojan coming at you from all sides Using the very effective tactic of multiple attack vectors, the makers of the Zbot banking Trojan are ensuring a high enough infection rate for them to make profit. If they follow the link, they are taken to a fake Fifth Third Bank website. When they enter their ID and password, it is automatically sent to a malware server. Large-scale attacks exploit unpatched PDF bug A week before Adobe is scheduled to patch a critical vulnerability in its popular PDF software, hackers are actively exploiting the bug with both targeted and large-scale attacks, a security researcher said today. The SANS Institute's Internet Storm Center (ISC) reported Monday that they'd received samples of a new rigged PDF document that hijacked PCs using a bug Adobe acknowledged Dec. 14 . Later last month, Adobe said it would not patch the bug until Jan. 12. In his write-up of the sample, ISC analyst Bojan Zdrnja called the attack PDF "sophisticated" and its use of egg-hunt shellcode "sneaky." "Egg-hunt shellcode" is a term for a multi-stage payload used when the hacker can't determine where in a process' address space the code will end up. Hacker pierces hardware firewalls with web page A hacker named Samy Kamkar demonstrated a way to identify a browser's geographical location by exploiting weaknesses in many WiFi routers. Now, he's back with a simple method to penetrate hardware firewalls using little more than some javascript embedded in a webpage. By luring victims to a malicious link, the attacker can access virtually any service on their machine, even when it's behind certain routers that automatically block it to the outside world. The method has been tested on a Belkin N1 Vision Wireless router, and Kamkar says he suspects other devices are also vulnerable. 54% of companies planning to deploy mobile antivirus in 2010 France considers tax for Google, Yahoo and Facebook A report, commissioned by the government, suggests firms such as Google, Yahoo and Facebook should pay a new tax on their online ad revenues. The money could be used to fund legal alternatives for buying books, films and music on the internet. But critics say the tax would be difficult to implement and Google says it could slow down innovation. President Nicolas Sarkozy has taken a tough line on the increasing dominance of digital content. France has just introduced tough new legislation aimed at removing those who persistently download illegal content from the net. It has also gone head-to-head with Google over its plans to digitise the world's books, with a project to set up its own digital library financed by the government to the tune of £700m. And it is considering a law which would give net users the option to have old data about themselves deleted. The clash between virtualization and compliance Specifically, I'm talking about the PCI DSS (Payment Card Industry Data Security Standard), probably the most stringent set of mainstream compliance regulations in effect. Though imposed by the credit card industry, not the government, PCI DSS stipulates fines for certain violations -- not to mention the far worse threat of having your authorization to process credit card transactions revoked. ISPs could cut spam easily, says expert According to Trend Micro's CTO, Dave Rand, who is leading a campaign to reform the way ISPs approach the matter of botnets and spam, the two countries that adopted such techniques, The Netherlands and Turkey, have seen a huge reduction in the numbers of botnetted PCs. According to his own figures and analysis, Turkey went from having around 1.7 million compromised PCs per month to only 35,000 after implementing techniques through its major ISP, Turk Telekom.
