Vulnerabilities and attacks

More Java-based malware plagues the cross-platform runtime

Java cannot seem to get a break. Only a few days after patching the last zero-day vulnerability, two more exploits are being found that make use of the runtime. One, as noted by Kaspersky, is a recent exploit of the latest runtime's attempts to install a McRAT executable by overwriting memory in the JVM that will trigger the executable to run.

Once installed, the McRAT malware will attempt to contact command and control servers and copy itself into dll files in Windows systems.

This malware is specifically Windows-based; however, a second one outlined by Intego, is a Minecraft password-stealing … Read more

China blames U.S. for most cyberattacks against military Web sites

China has accused the U.S. for most of the cyberattacks launched against its military networks.

In a statement released today, China's Ministry of National Defense said that cyberattacks against its military sites have increased over the past few years. Based on checks of IP addresses, the Defense Ministry claimed an average of 144,000 cyberattacks per month last year, according to Reuters.

And it fingered the U.S. for almost 63 percent of them.

The allegations from Beijing come hot on the heels of a recent report from U.S. security firm Mandiant, linking the Chinese army to cyberattacks … Read more

Overseas hackers nab more than 1TB of data daily

The idea of governments waging futuristic cyberbattles and online espionage campaigns actually isn't too farfetched. A new study released today by Team Cymru basically says as much.

The study, shared exclusively with The Verge, says that overseas hackers are stealing as much as one terabyte of data per day from governments, businesses, militaries, and academic facilities. Apparently, the hackers are using a network of 500 computer servers.

According to a lengthy article by The Verge, Team Cymru concludes that the hackers are so sophisticated and are running such massive campaigns that they must be state-sponsored. "This is Internet … Read more

'MiniDuke' malware takes aim at Euro governments via Adobe

A new attack is targeting European governments through flaws exploited in Adobe's Reader software, according to security researchers.

Kaspersky Lab and CrySys Lab today detailed a new malicious program in the wild, called "MiniDuke," that has been attacking government entities and institutions across Europe. Government entities in the Ukraine, Portugal, Romania, and others have been targeted, according to the security researcher.

MiniDuke finds its way to infected computers through PDFs. The malicious hackers -- who Kaspersky believes might have been dormant for some time because of the technique's similarity to those from the late-1990s -- have … Read more

NBC Web site back up after hack attack

NBC's Web site is up and running again after being knocked offline by a cyberattack for several hours yesterday.

The NBC site was the victim of a form of malware known as the Citadel Trojan. This specific strain targets companies in an attempt to steal usernames, passwords and other sensitive data. People who visit sites infected by the trojan can find their own PCs infected as well.

In the past, Citadel typically attacked banks and financial firms but has since expanded its reach to a wider range of organizations.

NBC, which is part of cable giant Comcast, is still trying to figure out how the attack occurred, … Read more

Malware getting smarter, says McAfee

Malware continues to grow, not just in volume but in sophistication, according to a new report from McAfee.

Released today, the security vendor's fourth-quarter 2012 Threats Report found that more organizations are being targeted by more clever cyberattacks.

The number of trojans designed to steal passwords rose 72 percent last quarter. Some of these trojans are part of "customized" threats, while others are packaged with more "off-the-shelf" forms of malware. As one example, the Citadel trojan was specifically designed to hit financial services companies.

Operation High Roller and Project Bliztkrieg were also cited by McAfee … Read more

China slams cyberattack accusations over lack of proof

China is refuting a report that names its military as the source of recent cyberattacks against the U.S.

A report released this week by U.S. security firm Mandiant linked the People's Liberation Army to a large number of cyberattacks against U.S. corporations, government agencies, and other organizations. The report specifically pointed the finger at Chinese military Unit 61398, noting that digital forensic evidence led investigators to the building housing that unit.

China's response?

As expected, the government has criticized the report, citing a lack of hard evidence. In a press conference held by China's … Read more
