Twitter Hacked, More Than 250,000 User Data Compromised

Twitter Hacked, More Than 250,000 User Data Compromised

The social networking giant and the world famous micro blogging site Twitter again fallen victim of cyber attack. Last year we have seen that the tight security system if twitter have been compromised many times. Yet again in this year the San Francisco based social media giant who have more than 500 million registered users failed to protect them selves from hackers. On last Friday Twitter acknowledged that it had become the latest victim in a number of cyber-attacks against media companies, saying hackers may have gained access to information on 250,000 of its more than 200 million active users. The micro blogging giant said in a blog posting that earlier this week it detected attempts to gain access to its user data. It shut down one attack moments after it was detected. According to reports usernames, email addresses, session tokens and encrypted/salted passwords for 250,000 users might have been accessed in what it described as a “sophisticated attack” 

"This attack was not the work of amateurs, and we do not believe it was an isolated incident,” said Bob Lord, Twitter’s director of information security. “The attackers were extremely sophisticated, and we believe other companies and organisations have also been recently similarly attacked” Bob added. 

Jim Prosser, a Twitter spokesman, would not say how hackers infiltrated Twitter’s systems, but Twitter’s blog post said hackers had broken in through a well-publicized vulnerability in Oracle’s Java software. Last month, after a security researcher exposed a serious vulnerability in the software, though Oracle patched the security hole, but Homeland Security said the fix was not sufficient. The DHS issued a rare alert that warned users to disable Java on their computers. Prosser said Twitter was working with government and federal law enforcement to track down the source of the attacks. For now, he said the company had reset passwords for, and notified, every compromised user. The company encouraged users to practice good password hygiene, which typically means coming up with different passwords for different sites, and using long passwords that cannot be found in the dictionary.
Twitter said it “hashed” passwords — which involves mashing up users’ passwords with a mathematical algorithm — and “salted” those, meaning it appended random digits to the end of each hashed password to make it more difficult, but not impossible, for hackers to crack. Once cracked, passwords can be valuable on auction-like black market sites where a single password can fetch $20.

While talking about Twitter and cyber issues, I would like to remind you that in last year twitter faced several cyber attacks where more than 55,000 twitter account details was leaked, after this issue in the middle of last year the social networking giant faced massive denial of service which interrupted its services. Later a huge number of Twitter users across the globe received  emails warning that their account have been compromised and their passwords had been reset, and it was another security breach which affected twitter. Such big organization are not at all careless about security, so as twitter and it has been proved when they hired renowned white hat hacker Charlie Miller to boost up their security, but after this current massacre, it seems that twitter need to think more and emphasize a lot to make sure that their system is good enough to prevent cyber attacks. For all the hot cyber updates and reviews stay tuned with VOGH.

Chinese Hackers Breached New York Times & Stolen Employee's Password

Chinese Hackers Breached New York Times & Stolen Employee's Password 

Yet again the story of cyber espionage by Chinese hackers spotted in the wild, when the famous and one of the most popular American news daily reported that their system has been compromised by a round of sophisticated cyber attack generated from China. After the hack of White House unclassified network, it is the second time in last six month; when Chinese hackers have targeted the American cyber spaceThe New York Times has reported that for the last four months Chinese hackers have been infiltrating its networks, broken into the email accounts of senior staff, stolen the corporate passwords for every Times employee and used those to gain access to the personal computers of  more than 50 employees
According to a blog post of NYT - The timing of the attacks coincided with the reporting for a Times investigation, published online on Oct. 25, that found that the relatives of Wen Jiabao, China’s prime minister, had accumulated a fortune worth several billion dollars through business dealings. Security experts hired by The Times to detect and block the computer attacks gathered digital evidence that Chinese hackers, using methods that some consultants have associated with the Chinese military in the past, breached The Times’s network. They broke into the e-mail accounts of its Shanghai bureau chief, David Barboza, who wrote the reports on Mr. Wen’s relatives, and Jim Yardley, The Times’s South Asia bureau chief in India, who previously worked as bureau chief in Beijing. 
“Computer security experts found no evidence that sensitive e-mails or files from the reporting of our articles about the Wen family were accessed, downloaded or copied,” said Jill Abramson, executive editor of The Times. The hackers tried to cloak the source of the attacks on The Times by first penetrating computers at United States universities and routing the attacks through them, said computer security experts at Mandiant, the company hired by The Times. This matches the subterfuge used in many other attacks that Mandiant has tracked to China.

Cyber Espionage of China (2011-2012) at a Glance:-
While talking about this cyber attack, we would like to refresh your memory last two years, where the scenario of big cyber attack and espionage by Chinese hackers have been spotted several times. In 2012 Chinese hackers had  breached Telvent's corporate network & gained control of US Power GridAlso in the middle of last year, we have seen that Chinese hackers have broken into Indian Navy's Computer System & stolen sensitive data. Few months before this hack, Tokyo based computer security firm Trend Micro confirmed that Chinese hackers were responsible for biggest cyber-espionage in India, Japan & Tibet. Also the director of National Security Agency (NSA) General Keith Alexander confirmed that hackers from China was responsible for the serious attack on one of the leading IT security & cyber security company RSAAlso in 2011 China was responsible behind the attack on US Chamber of Commerce, Satellite System of U.S, Nortel Network & so on.  But few days ago National Computer Network Emergency Response Coordination Center of China (CNCERT/CC), China's primary computer security monitoring network claimed that China fallen victim of one of biggest cyber attacks originated from US, Japan & South Korea. We must have to say that this statement is truly irrelevant. Cyber crime investigator have found that China was directly responsible for the hack into Japan's Biggest Defense Contractor Mitsubishi, Japan Aerospace Exploration Agency (JAXA) & Parliament of Japan. In case of South Korea  more than 13 Million of MapleStory players data has been stolen, there also hackers from China was responsible. 
All those above stories it has been clearly identified that China was the point of those said attacks, but it doesn't necessarily prove that it the operation is backed by the Chinese government or intelligence services. It could just as easily be a patriotic group of skilled, independent Chinese hackers upset with how the Western media is portraying their country's rulers. For all kind of cyber related topics and expert reviews on those matters just stay tuned  with only VOGH

3 Russian Cyber Criminal Who Was The Master Mind of Banking Trojan 'Gozi' Charged in New York

3 Russian Cyber Criminal Who Was The Master Mind of Banking Trojan 'Gozi' Charged in New York 

Yet again another serious issue of cyber crime get resolved when the FBI tracked and figured out the master mind of infamous 'Gozi banking Trojan' which effected more than millions of system world wide, including a handful at NASA, leading to tens of millions of dollars in lost banking funds and damages to computer systems and networks. Three alleged international cyber criminals from Russia, responsible for creating and distributing 'Gozi' that infected over one million computers and caused tens of millions of dollars in losses charged in Manhattan Federal Court. Mihai Ionut Paunescu aged 28, a Romanian, Deniss Calovskis, 27, a Latvian, and Nikita Vladimirovich Kuzmin, 25, of the Russian Federation, are charged with computer intrusion, conspiracy to commit bank and wire fraud and access device fraud. Federal authorities said the three were arrested last week; Kuzmin is being held in New York, while Paunescu is in custody in Romania and Calovskis in Latvia. 
According to the press release of FBI -Deniss Calovskis, a/k/a “Miami,” a Latvian national who allegedly wrote some of the computer code that made the Gozi virus so effective, was arrested in Latvia in November 2012. Mihai Ionut Paunescu, a/k/a “Virus,” a Romanian national who allegedly ran a “bulletproof hosting” service that enabled cyber criminals to distribute the Gozi virus, the Zeus trojan, and other notorious malware and to conduct other sophisticated cyber crimes, was arrested in Romania in December 2012. 

The cases are being handled by the Complex Frauds Unit of the United States Attorney’s Office. Assistant United States Attorneys Sarah Lai, Nicole Friedlander, and Thomas G.A. Brown, along with Trial Attorney Carol Sipperly of the Computer Crime and Intellectual Property Section of the Department of Justice on the Paunescu case, are in charge of the prosecution. The charges contained in the Indictments are merely accusations, and the defendants are presumed innocent unless and until proven guilty.

Brief About Gozi:-
The Gozi virus is malicious computer code, or “malware,” that steals personal bank account information, including usernames and passwords, from the users of affected computers. It was named by private sector information security experts in the U.S. who, in 2007, discovered that previously unrecognized malware was stealing personal bank account information from computers across Europe on a vast scale, while remaining virtually undetectable in the computers it infected. To date, the Gozi virus has infected over one million victim computers worldwide, among them at least 40,000 computers in the U.S., including computers belonging to the National Aeronautics and Space Administration (NASA), as well as computers in Germany, Great Britain, Poland, France, Finland, Italy, Turkey, and elsewhere, and it has caused tens of millions of dollars in losses to the individuals, businesses, and government entities whose computers were infected.

The Gozi virus was distributed to victims’ computers in several different ways. In one method, the virus was disguised as an apparently benign .pdf document which, when opened, secretly installed the Gozi virus on the victim’s computer. Once installed, the Gozi virus—which was intentionally designed to be undetectable by anti-virus software—collected data from the infected computer in order to capture personal bank account information including usernames and passwords. That data was then transmitted to various computer servers controlled by the cyber criminals who used the Gozi virus. These cyber criminals then used the personal bank account information to transfer funds out of the victims’ bank accounts and ultimately into their own personal possession.

WikiLeaks Tweet Revealed- Aaron Swartz Was an Ally & Possible Source of WikiLeaks

WikiLeaks Tweet Revealed- Aaron Swartz Was an Ally & Possible Source of WikiLeaks 

WikiLeaks, the organization who used to dig the truth and bring them in front, has disclosed a sensational matter while saying that the late internet activist and renowned hacker Aaron Swartz who committed suicide a few weeks ago was possibly an active worker and source for WikiLeaks

Over the weekend, in a series of tweets, WikiLeaks said that activist and hacker Swartz, who committed suicide earlier this month while awaiting trial on computer fraud charges, "assisted" the organization and "was in communication with Julian Assange, including during 2010 and 2011,"  

Unfortunately those tweets did not go so far as to name Swartz as a WikiLeaks source, only saying, "We have strong reasons to believe, but cannot prove, that" he was. 

WikiLeaks -globally famous for exposing classified classified and top secrete documents of several government said it decided to reveal these details in light of the US Secret Service's involvement in Swartz's  case. At the time of his death, Swartz was awaiting trial for allegedly harvesting millions of scholarly articles over the Massachusetts Institute of Technology's network. He was charged with computer fraud and other crimes in July 2011, and faced up to 35 years in prison. 
Although WikiLeaks doesn't elaborate on its decision, the organization has a policy of maintaining anonymity for its sources. "As far as we can ascertain, WikiLeaks has never revealed any of its sources," according to its website. "We cannot provide details about the security of our media organization or its anonymous drop box for sources because to do so would help those who would like to compromise the security of our organization and its sources."  But after these round of tweets we can say that Wikileaks may have broken its own rules of anonymity by doxxing (removing the anonymity) of Swartz as an ally and possible source.

Anonymous Targeted Mexican Defense, Navy & Ministry Websites

Anonymous Targeted Mexican Defense, Navy & Ministry Websites 

The whole cyber world can be the witness of bitter relation between hacker collective group Anonymous and the Mexican government. We those who used to observe the cyber domain have already seen several protest campaign came from Anonymous against Mexico, whether it was the Pope or Mexican Drug Cartels or Mexican Govt. sponsored bus organization. Here again the same thing get repeated when the infamous Anonymous targeted  several web sites of Mexico’s defense and navy departments. 
The name of the group "Anonymous Mexico" was visible on the website in front of a black background, with phrases from the manifesto of the Zapatista National Liberation Army (EZLN). The group MexicanH Team, which identified itself as part of Anonymous Mexico, said on Twitter that it had hacked and "defaced" the ministry website. In another Twitter account, the group Anonymous Hispano, which uses the handle @anonophispano, claimed that "the entire content" of the defense ministry server was hacked and that it will be "released soon." 
“Brothers and sisters, let’s raise our voices for a Mexico free of corruption, free of crime,” the message said. “Let’s show the world that were are one, we are everyone. We are anonymous. We are legion. We don’t forgive. We don’t forget. Wait for us!” -added by the hacker. 
In response of hacking, the Defense Ministry responded that its website was “momentarily out of service” but did not explain why and did not refer to the hacking claim. But on the other hand the Mexican Navy accommodated the cyber attack and said that- its web site was targeted only by a simple denial-of-service, attack and that no sensitive information was compromised. Later Sedena issued a statement hours later saying that while its Web site was indeed temporarily down, but the department’s internal information and communication systems were “functioning with complete normality.” And After couple of hours all the services and website came back live with proper functionality.

DHS & US-CERT Recommended to Disable Java in Web Browsers

DHS & US-CERT Recommended to Disable Java in Web Browsers Unless It's Absolutely Necessary

The running time is proving to be the worst period for Java, as it has been walking under serious security issues. Yet again security researchers have pointed out a zero-day security vulnerability in the Java program that hackers are exploiting. The exploit takes advantage of a vulnerability left open in Java 7 Update 10, released in October last year. It works by getting Java users to visit a website with malicious code that takes advantage of a security gap to take control of users' computers. Thus how Java is being used by cyber criminals to infect computers with malware. Oracle, hasn't specified the number of users who have downloaded Java 7 Update 10. However, Java runs on more than 850 million computers and other devices. When Oracle released Update 10, so it is predictable that more than 850 million devices run by Java is under threat. The exploit was first discovered by French researcher Kafeine, who claimed to have found it running on a site registering hundreds of thousands of page views daily. From that site, immediately that vulnerability and a large number of effected devices has been spotted in the wild. In Java 7 Update 10 the creator of Java, Oracle added several security control and fixed older bugs and promised more security enhancement, but its very unfortunate that Oracle failed to keep their promise. What ever after this newly discovered 0-day hole spotted wildly, Oracle Security Alert CVE-2013-0422 states that Java 7 Update 11 addresses this (CVE-2013-0422) and an equally severe, but distinct vulnerability (CVE-2012-3174). Immunity has indicated that only the reflection vulnerability has been fixed and that the JMX MBean vulnerability remains. Java 7u11 sets the default Java security settings to "High" so that users will be prompted before running unsigned or self-signed Java applets. It "strongly recommends" that Java SE 7 users upgrade immediately to avoid all kind of security hazards. 

After seeing all the drama, many of you have failed to keep trust in Java, and you all will be relieved when you will gone through the security advisory of CERT (Computer Emergency Response Team) where they have clearly instructed to disable Java in your popular web-browser. In their official release CERT said "Unless it is absolutely necessary to run Java in web browsers, disable it as described below, even after updating to 7u11. This will help mitigate other Java vulnerabilities that may be discovered in the future."

You will see similar advice in the advisory posted on the official DHS US-CERT website where DHS also suggested to disable Java until and unless it is that much necessary. "To defend against this and future Java vulnerabilities, consider disabling Java in web browsers until adequate updates are available. As with any software, unnecessary features should be disabled or removed as appropriate for your environment." - said U.S. CERT in their advisory.
