Japan nuclear agency raises threat level

For Japan's nuclear leakage, the agency raises the level from 5 to 7, 7 is the highest possible level and is on par with Chernobyl. Japan's government has called for further evacuations.

This raised the public concern again for the possible radiation transport by air to nearby country. We had done canceling our trip to Korea as the result of this! I am now focusing on my website development instead.

Tokyo (CNN) -- Japanese authorities Tuesday "provisionally" declared the country's nuclear accident a level-7 event on the international scale for nuclear disasters -- the highest level -- putting it on par with the 1986 Chernobyl disaster.

Japan's Nuclear and Industrial Safety Agency announced the new level Tuesday morning. It had previously been at 5.

Regulators have determined the amount of radioactive iodine released by the damaged reactors at the Fukushima Daiichi nuclear plant was at least 15 times the volume needed to reach the top of the International Nuclear Event Scale, the agency said. That figure is still about 10 percent of the amount released at Chernobyl, they said.

The amount of radioactive Cesium-137, which has a half-life of 30 years, is about one-seventh the amount released at Chernobyl, according to the agency.

Hackers hunt prey on smartphones, Facebook

This news is published in

Hackers are following prey onto smartphones and social networking hotspots, according to reports released Tuesday by a pair of computer security firms.

Cyber criminals are also ramping up the sophistication and frequency of attacks on business and government networks, one of the companies, Symantec, said in the latest volume of its Internet Security Threat Report.

Symantec depicted a "massive" volume of more than 286 new computer threats on the Internet last year, continued growth in attacks at online social networks and "a notable shift in focus" by hackers to mobile devices.

"The major mobile platforms are finally becoming ubiquitous enough to garner the attention of attackers," Symantec said in its findings.

In March, smartphones running on Google-backed Android software were the target of the largest attack ever on the devices, noted a PandaLabs report focused on the first three months of this year.

"This assault was launched from malicious applications on Android Market, the official app store for the operating system," PandaLabs said.

Within a four-day span, seemingly legitimate Android smartphone applications rigged with malicious "Trojan" computer code were downloaded more than 50,000 times, according to PandaLabs.

"The Trojan steals personal information from cellphones, and downloads and installs other apps without the user's knowledge," the computer security firm said.

"Google managed to rid its store of all malicious apps, and several days later removed them from users' phones."

The Symantec report indicated that cyber crooks were also infiltrating news-feed capabilities at popular social networking services to "mass-distribute" attacks.

Such tactics typically involve getting into one person's account at a social network and then sending others links to websites booby-trapped with malicious computer code.

"Social network platforms continue to grow in popularity and this popularity has, not surprisingly, attracted a large volume of malware," Symantec said.

PandaLabs gave an example of a 23-year-old California man facing sentencing after pleading guilty to using information found on Facebook to hack email accounts to find compromising messages for blackmail.

Even Facebook founder Mark Zuckerberg saw his fan page at the social networking website hacked this year, the security firm noted.

PandaLabs researchers logged an average of 73,190 new snippets of malicious computer code daily during the first three months of this year in what was said to be a 26 percent jump from the same period in 2010.

Hackers showed a strong predeliction for a kind of malicious code used to mine bank account data and, ultimately, get into people's accounts, the computer security firm indicated.

China, Thailand and Taiwan had the highest rates of infection, with nearly 70 percent of the computers in those countries "riddled with malware," according to PandaLabs.

Many attacks on company or government computer networks involved hackers researching key employees and then duping them or colleagues into enabling access to protected networks, Symantec's report showed.

Researchers warned that onslaughts by "hacktivists" such as the group "Anonymous" and others with seeming political goals could signal a dangerous cyber arms race.

"Stuxnet and Hydraq, two of the most visible cyber-events of 2010, represented true incidents of cyberwarfare and have fundamentally changed the threat landscape," said Symantec Security Technology and Response senior vice president Stephen Trilling.

"The nature of the threats has expanded from targeting individual bank accounts to targeting the information and physical infrastructure of nation states."

Is email marketing service the cause of the hack?

Traditional chinese medicine

I have been eating traditional chinese medicine for more than a month, the result is quite significant. My face is now growing rosy pink. And overall, I am more energetic compared to previous days when I am always fatigue.

I was not confident with traditional chinese medicine initially, and from the beginning of the intake of traditional chinese medicine, I am extremely fatigue for a whole week. However, I am getting better day by day.

Via the search engine marketing, I have found some information about traditional chinese medicine:

Traditional Chinese medicines are made from plants and herbs, and occasionally from organ meats or other substances. Medicinals are typically constructed from a number of materials designed - according to its theory - to stimulate certain organ systems or to balance out the undesired aspects of other materials used. These are often provided in dried form to be steeped into a tea, though practitioners may suggest them as dietary changes instead - adding certain organ meats or herbs to meals, for instance - or they may be powdered and used in pill form. There are roughly 13,000 medicinals used in China and over 100,000 medicinal recipes recorded in the ancient literature. Some conceptions of the theory believe that toxicity is needed to fight pathogens in the body, similar to homeopathy, so chemicals considered to be toxic are used in some preparations. Further, ingredients may have different names in different locales or in historical texts, and different preparations may have similar names for the same reason, which creates inconsistencies and confusion in the creation of medicinals, resulting in poisoning.
