Exclusive: National Security Agency helps banks battle hackers (Reuters)

WASHINGTON (Reuters) – The National Security Agency, a secretive arm of the U.S. military, has begun providing Wall Street banks with intelligence on foreign hackers, a sign of growing U.S. fears of financial sabotage.

The assistance from the agency that conducts electronic spying overseas is part of an effort by American banks and other financial firms to get help from the U.S. military and private defense contractors to fend off cyber attacks, according to interviews with U.S. officials, security experts and defense industry executives.

The Federal Bureau of Investigation has also warned banks of particular threats amid concerns that hackers could potentially exploit security vulnerabilities to wreak havoc across global markets and cause economic mayhem.

While government and private sector security sources are reluctant to discuss specific lines of investigations, they paint worst-case scenarios of hackers ensconcing themselves inside a bank's network to disable trading systems for stocks, bonds and currencies, trigger flash crashes, initiate large transfers of funds or turn off all ATM machines.

It is unclear if hackers have ever been close to producing anything as dire, but the FBI says it has already helped banks avert several major cyber attacks by helping identify network vulnerabilities.

NSA Director Keith Alexander, who runs the U.S. military's cyber operations, told Reuters the agency is currently talking to financial firms about sharing electronic information on malicious software, possibly by expanding a pilot program through which it offers similar data to the defense industry. He did not provide further details on his agency's collaboration with banks.

Alexander said industry and government were making progress in protecting computer networks, but "tremendous vulnerabilities" remained. The four-star Army general noted companies that have suffered damage from hackers, such as Google Inc, Lockheed Martin Corp and Nasdaq OMX Group, had among the best security systems in the world.

"If they're getting exploited, what about the rest? We have to change that paradigm," Alexander said.

NSA, which has long been charged with protecting classified government networks from attack, is already working with Nasdaq to beef up its defenses after hackers infiltrated its computer systems last year and installed malicious software that allowed them to spy on the directors of publicly held companies. A Nasdaq spokesman confirmed the investigation into the attack continues, but declined to give further details.

OFFICIALS WORRIED

Hackers have targeted Wall Street investment banks for more than a decade, but recent attacks have been more sophisticated, coordinated and deliberate.

That makes security experts suspect the hackers were backed by countries such as China, and fueled concerns that cyber terrorists might someday use malware to wipe out crucial data and cripple networks across the financial sector.

China has repeatedly said it does not condone hacking, but experts say the evidence continues to mount against Beijing. In June, Google blamed China for an attempt to steal the passwords of hundreds of email account holders, the second major breach the Internet giant has blamed on the Chinese.

Earlier this year, security firm McAfee said hackers working in China broke into the computer systems of five global oil and gas companies to steal bidding plans and other critical proprietary information.

"We know adversaries have full unfettered access to certain networks," Shawn Henry, executive assistant director of the FBI, said without identifying the adversaries.

"Once there, they have the ability to destroy data," he said in an interview. "We see that as a credible threat to all sectors, but specifically the financial services sector."

The FBI has helped banks avert several potential attacks by alerting them to vulnerabilities in their computer networks, and by flagging possible hackers before they struck, he said.

Security experts interviewed by Reuters declined to identify any banks that may have data compromised, citing promises of confidentiality to clients, colleagues and employers that they would not to discuss the matter publicly.

Representatives of Wall Street's biggest banks including Bank of America Corp, Citigroup Inc, Goldman Sachs Group Inc and JPMorgan Chase & Co either declined to discuss security issues or were not available to comment.

Hackers expose flaw in Apple iPad, iPhone software (Reuters)

BOSTON (Reuters) – Hackers have disclosed a bug in software from Apple Inc that security experts said could be exploited by criminals looking to gain remote control over iPhones, iPads and iPod Touch devices.

The security flaw in Apple's iOS operating system came to light on Wednesday as the website www.jailbreakme.com released code that Apple customers can use to modify the iOS operating system through a process known as "jail breaking."

Some Apple customers choose to jail break their devices so they can download and run applications that are not approved by Apple or use iPhone phones on networks of carriers that are not approved by Apple.

Security experts warned that criminal hackers could download that code, reverse engineer it to identify a hole in iOS security and build a piece of malicious software within a few days.

"If you are a malicious attacker, it is fairly doable," said Patrik Runald, a senior researcher with the Internet security firm Websense.

Apple has yet to release an update to iOS that protects customers against malicious software that exploits the flaw.

Apple spokeswoman Trudy Muller said the company was aware of the problem.

"We are developing a fix that will be available to customers in an upcoming software update," Muller said.

Apple has long been vocal against jail breaking, which if done voids the warranty on its devices.

Any security flaw in iOS software -- which runs Apple's iPhone, iPad tablet and iPod Touch -- has the potential to affect millions of devices that are at the core of Apple's business.

Apple has sold 25 million iPads since it launched last year. The company sold over 18 million of its popular iPhones in just the first three months of the year.

Hackers can exploit the iOS vulnerability by creating a malicious PDF document file. It would infect Apple devices when users attempt to open that document, according to Runald.

Once the device is infected, hackers could "do anything they want," Runald said. That includes stealing passwords, documents and emails.

Comex, a 19-year-old hacker from New York State who developed the jail-breaking tool, said that Apple might be able to patch the software before criminal hackers develop software that exploits the bug.

Last time he put out a version of his jailbreaking software, Apple was able to issue a patch before anybody exploited the bug for malicious purposes.

He said that Apple might not be able to move quickly enough this time.

"It's not that hard to reverse engineer," he said via telephone.
