Update: New 25 GPU Monster Devours Passwords In Seconds

Update: New 25 GPU Monster Devours Passwords In Seconds

Editor’s note: I’ve updated the article with some new (and in some cases) clarifying detail from Jeremi. I’ve left changes in where they were made. The biggest changes: 1) an updated link to slides 2) clarifying that VCL refers to Virtual OpenCL and 3) ┬áthat the quote regarding 14char passwords falling in 6 minutes was for LM encrypted – not NTLM encrypted passwords. Long (8 char) NTLM passwords would take much longer…around 5.5 hours. ­čśë ┬á– Paul There needs to be some kind of Moore’s law analog to capture the tremendous advances in the speed of password cracking operations. Just within the last five years, there’s been an explosion in innovation in this ancient art, as researchers have realized that they can harness specialized silicon and cloud based computing pools to quickly and efficiently break passwords. A presentation at the Passwords^12 Conference in Oslo, Norway (slides available here┬á– PDF), has […]

Uncle Sam Wants To Stop Healthcare Fraud, But Smart Cards Are No Panacea

Uncle Sam Wants To Stop Healthcare Fraud, But Smart Cards Are No Panacea

Medical fraud is a huge issue in the U.S. Depending on whose numbers you use, fraud stemming from false medical claims and reimbursements range from $65 billion a year (a figure generated by the Centers for Medicare and Medicaid Studies) to more than ten times that: $750 billion a year (according to the Institute for Medicine). To stem the losses, government and law enforcement have been cracking down on fraud. In October, for example, the U.S. Attorney General Eric Holder and Health and Human Services Secretary Kathleen Sebelius announced charges against 91 individuals believed to be behind a huge, interstate Medicare fraud scheme responsible for some $430 million in false billing charges. Increasingly, though, the U.S. government is turning to technology to help it identify and root out fraud within the system for medical reimbursements. Chief among the ideas under consideration is a beefed up system for identifying health consumers […]

Latest Iranian Malware Targets Financial Software

Latest Iranian Malware Targets Financial Software

There appears to be some professional differences of opinion about the latest super malware targeting the nation of Iran. ┬áJust days after Symantec Corp. warned about a new piece of malware, W32.Narilam, ┬áresearchers at the Russian anti-virus firm Kaspersky Lab threw cold water on the report, saying their analysis suggests that Narilam is two to three years old and probably targeted financial software packages, rather than high value government or industrial systems. The back and forth started with Symantec’s Nov. 22nd blog post on Narilam, which claimed the malware had recently been found circulating in the “Middle East” – and particularly in Iran. Narilam was programmed to infect systems running Microsoft’s SQL database software, spreading through removable drives and network shared folders. It was designed to corrupt data, not to steal information, Symantec said. Though the Cupertino company made no attestation as to Narilam’s origins, Symantec did say the worm […]

Profile Poisoning the Next Frontier for Hackers

Google and Facebook already know everything about you – your interests, friends, tastes and even your movements. That’s already a privacy nightmare, but researchers at the Georgia Institute of Technology’s Information Security Center (GTISC) think it could soon be a security nightmare, also. Automated information systems already determine what version of the news most of us see. But researchers at Georgia Tech warn that the power of such systems to shape what each of us see online could soon become a powerful tool in the hands of sophisticated attackers, who might look for ways to manipulate victims’ online profile to steer them to certain sites, according to the report “Emerging Cyber Threats Reports 2013.” Researchers at Georgia Tech said attacks that manipulate a victim’s search history, part of their online profile, using cross-site request forgery are already technically feasible. In practice, they would allow for a kind of super-search engine […]

Report: Insecure SEC Laptops Toted To Black Hat

Report: Insecure SEC Laptops Toted To Black Hat

What’s worse than neglecting to encrypt the data on the government-issue laptop you use to handle sensitive data related to the workings of U.S. equities markets? How about hopping on a plane and bringing said laptop with you to the Black Hat conference in Las Vegas, one of the world’s largest gatherings of hackers. That’s just one of the allegations in an as-yet unreleased Inspector General report on irregularities at the U.S. Securities and Exchange Commission (SEC), according to a report on Friday by Reuters. The Inspector General’s report, a copy of which was reviewed by Reuters, found evidence of widespread lapses in information security within the agency that acts as a watchdog over stock markets and exchanges within the U.S. Among other errors, staff at the SEC failed to encrypt laptops containing sensitive stock exchange data or even install antivirus software on those systems, Reuters reported. The Inspector General […]
