White House Cyber Chief: JP Morgan Underscores Critical Infrastructure Risk

The White House’s cyber security czar, Michael Daniel, said the Obama Administration is deeply concerned about the reported hack of systems belonging to banking giant JP Morgan Chase & Co. but sees the incident as part of a larger trend of attacks against U.S. critical infrastructure. Asked about the targeted attack against JP Morgan and other banks and financial institutions, Daniel said that the White House was concerned, but not surprised by the incident. “We have watched for several years the trend of malicious actors in cyber try to figure out how to target critical infrastructure,” he said. “Financial services is critical infrastructure.” The White House was concerned that a major U.S. bank would fall victim to hackers, but sees it in the context of a “broad trend,” rather than an isolated incident, he said. Speaking with Michael Farrell, the Cybersecurity Editor at Christian Science Monitor, Daniel hit on many of the now-common talking […]

Was An IPMI Flaw Behind 300Gbps DDoS Attack? – ComputerworldUK.com

Computerworld UK has an interesting story that digs into a massive, 300 Gbps DDoS attack that used a flaw in the IPMI protocol to compromise 100,000 unpatched servers, which were then used to send junk traffic to the victim site. The attack was documented by the security firm VeriSign in its quarterly threat report. The flaw, in the Intelligent Platform Management Interface (IPMI) is a well-documented security hole that affects a wide range of devices. The attack in question took place in June and targeted what Verisign described as a content delivery network (CDN) in the media and entertainment sector. The attack combined a variety of techniques, including SYN, TCP and UDP protocols to flood a target data center. The attacks reached a peak traffic volume 300 Gbps and lasted more than a day, prompting Verisign to balance the load across its global network. Verisign attributed the massive volume of the attack to a botnet made up […]

Report: CIA Fears the Internet of Things | Nextgov.com

A story by Patrick Tucker over at Nextgov.com picks up on some comments from Dawn Meyerriecks, the deputy director of the Central Intelligence Agency’s directorate of science and technology regarding the agency’s thinking about the Internet of Things. Meyerriecks was speaking at The Aspen Institute’s Security Forum on Thursday of last week in a panel on “The Future of Warfare.” Speaking about the topic of cyber warfare, she said that current debates about the shape of cyber war don’t address the “looming geo-security threats posed by the Internet of Things.” Meyerriecks cited the now-debunked Proofpoint report about smart refrigerators being used in spam and distributed denial of service attacks.” She also mentioned “smart fluorescent LEDs [that are] are communicating that they need to be replaced but are also being hijacked for other things.” Those might be some sensational (and dubious) examples, but Meyerriecks main point was more pedestrian: that we’re on the cusp of disruptive […]

Report: AdWords Fraudbot Helps E-Commerce Firms Compete

One of the more interesting stories to come out this week is from Brian Krebs over at Krebsonsecurity.com. Writing on Friday, Krebs used his prodigious knowledge of the cyber underground to profile “GoodGoogle,”  one of a growing number of specialized online fraud services that helps e-commerce firms target competitors by gaming Google’s AdWords feature. As you probably know, AdWords are one of Google’s biggest sources of revenue. They allow companies with products or services to sell to “bid” on words or phrases (like “Internet of Things”). Users who search on those terms will see hyperlinked ads to the right of their search results that link to a site of the advertiser’s choosing. Advertisers pay a premium to own popular (and lucrative) keywords – more than $40 per click for keywords like “loan,” “insurance,” “mortgage” or “attorney” depending on the word and time of day. Typically, advertisers set a certain daily budget […]
