Former VA official tells lawmakers of state-sponsored computer hacking at VA

WASHINGTON - At least eight foreign-sponsored organizations have hacked into computer networks at the Veterans Affairs Department in recent years or were actively trying to do so, a former VA computer security chief told Congress on Tuesday.

Jerry Davis, who served as the VA's chief information security officer until February 2013, said in written testimony to a House subcommittee that the VA became aware of the computer hacking in March 2010 and that attacks continue "to this very day."

Davis said the hacking "successfully compromised VA networks and data," but he did not indicate how the information may have been used. The intrusions raise the potential for identity theft and could complicate efforts to share data with the Pentagon, long viewed as key to quicker processing of disability claims.

"The entire veteran database in VA, containing personally identifiable information on roughly 20 million veterans, is not encrypted, and evidence suggests that it has repeatedly been compromised since 2010 by foreign actors, including in China and possibly in Russia," said Rep. Mike Coffman, R-Colo., chairman of the House Veterans' Affairs oversight and investigations subcommittee.

Officials with the VA's inspector general's office said the main threat to veterans would appear to be credit card theft. They also could not point to any specific instances in which such fraud has occurred. Investigators also said hackers had obtained access to the emails of senior VA managers, but did not know what had been done with the emails.

Linda Halliday, an assistant inspector general, said investigators were seeing fewer weaknesses with the VA's computer security, but she told lawmakers that 4,000 weaknesses and vulnerabilities have not been addressed. She cited weak passwords and user accounts with inappropriate access as among the most common problems.

Stephen Warren, acting assistant secretary for information and technology at the VA, said the state of computer security at the VA was something he wrestled with continually, but the inspector general's citation of security threats dealt with what could go wrong. He said that's not the same as the removal of information from the VA's computers.

"We're talking about potential. We're not talking about actuals," Warren said in describing the computer security problem at the VA.

Warren told the hearing he disagreed with Coffman's assessment that the VA's computer systems had been compromised repeatedly by foreign entities. He said he knew of only one such instance. He declined to cite which country that involved, saying he would prefer to discuss it in a closed session.

At another point in the hearing, Warren said he was aware of more than one foreign entity that had attempted to hack into the VA's systems. He said such attacks go beyond foreign governments, but through crime syndicates seeking financial gain.

Gmail accounts targeted by 'state-sponsored attackers' using Internet Explorer zero-day vulnerability

Over 170,000 people are part of the Sophos community on Facebook. Why not join us on Facebook to find out about the latest security threats.

Hi fellow Twitter user! Follow our team of security experts on Twitter for the latest news about internet security threats.

IE and GmailBoth Google and Microsoft have put out alerts about an unpatched, zero-day hole in Internet Explorer that didn't get fixed on Patch Tuesday and is actively being exploited in the wild.

According to ZDNet, those attacks are apparently being launched by the "state-sponsored attackers" that Google warned Gmail users about last week.

Neither Google nor Microsoft referred to those state attackers in their respective security warnings. ZDNet attributed that particular detail to a source it said was "close to these investigations".

This source confirmed to ZDNet that the attacks motivated Google to warn Gmail users last week about the attackers.

As ZDNet pointed out, Gmail users have been reporting on Twitter that they've been hit by the Gmail warning.

Google security engineer Andrew Lyons wrote in the company's security blog that Google reported the vulnerability to Microsoft on May 30 and that the two companies have been working on the problem since.

He wrote on Tuesday:

Today Microsoft issued a Security Advisory describing a vulnerability in the Microsoft XML component. We discovered this vulnerability - which is leveraged via an uninitialized variable - being actively exploited in the wild for targeted attacks.

Lyons said that the attacks are spreading both from malicious web pages set up to snare Internet Explorer users and through Office documents.

Users running any flavor of supported Windows are vulnerable, from XP onwards up to and including Windows 7. All supported editions of Microsoft Office 2003 and Microsoft Office 2007 are also vulnerable.

The hole hasn't been stitched up yet, but Microsoft is suggesting a workaround that will help prevent it from being exploited.

Microsoft Fix itMicrosoft's security advisory recommends that IE and Office users immediately install a Fix it solution, downloadable with instructions from Microsoft Knowledge Base Article 2719615, until the company gets the final fix out.

The vulnerability crops up when Microsoft XML Core Services 3.0, 4.0, 5.0, and 6.0 try to access an object in memory that hasn't been initialized, which can corrupt memory such that an attacker could execute arbitrary code on a hijacked machine.

A victim would have to visit a maliciously crafted site using IE to suffer an attack. An attacker might lure users into visiting a boobytrapped site by enticing them to click on a link in an email or via messaging.

A successful attack grants the intruder the same user rights as the logged-on user. Therefore, a mitigating factor is to configure accounts with fewer rights, as opposed to operating with administrative user rights.

Microsoft noted that by default, IE on Windows Server 2003, Windows Server 2008, and Windows Server 2008 R2 runs in a restricted mode known as Enhanced Security Configuration. That also mitigates the vulnerability.

As far as bolting down Gmail goes, Sophos's Graham Cluley has a collection of tips on how to stop your Gmail account from getting hacked.

Gmail login screenIt's definitely worth a read. Here's a quick cheat-sheet; Graham gives you more detail on these items in his article:

OK, that last one's not a tip, per se, but it's food for thought if you are, in fact, important enough that a state would want to attack your Gmail account.

If you are, think twice about using a free web email provider for sensitive information. If you're working for the government or the military, like Graham said, put all that sensitive information on secure systems instead.
