Popular Web Sites Still Getting Gamed in SEO Attacks

In this post, Security Ledger contributor Or Katz of Akamai provides details of how malicious actors are abusing redirect vulnerabilities in popular web sites to boost the reputation of malicious sites they control. One recent attack involved the compromise of some 4,000 vulnerable web applications for the purpose of pumping up the search engine ranking of more than 10,000 malicious web sites, Katz reveals. 

Researchers Warn Of Flaws In Popular Password Managers

Researchers from the University of California, Berkeley have published a paper describing security holes in five, web-based password managers including LastPass, My1login and Roboform. According to the paper  (PDF), four out of the five password managers inadvertently leaked a user’s credentials for stored web sites due to all-too-common web based security flaws like Cross Site Request Forgery (CSRF) and Cross Site Scripting (XSS). The researchers, Zhiwei Li, Warren He, Devdatta Akwawe and Dawn Song, all of the University of California Berkeley, said that they disclosed the holes in August of last year and that all of the affected firms and that all but one – NeedMyPassword – have since patched the vulnerabilities. All the password managers tested were found to contain one of a short list of security problems. Either they were vulnerable to classic web-based holes (like XSS), or they were found to be susceptible to user interface-focused attacks, like […]

Google Warns Of Dodgy Digital Certificates Issued By India

Beware of Google domains bearing gifts – especially gifts from India. On Tuesday, Google’s Adam Langley took to the company’s security blog to warn about unauthorized digital certificates that have been issued by India’s National Informatics Centre (NIC) and used to vouch for “several Google domains.” Google notified the NIC, as well as India’s Controller of Certifying Authorities (or CCA) and Microsoft about the discovery and the certificates have been revoked, Langley said. As Cory Doctorow noted over at BoingBoing.net, most operating system vendors and browser makers don’t trust NIC-issued certificates as a matter of course. However, NIC holds intermediate CA (certificate authority) certificates that are trusted by India’s CCA, and CCA-trusted certificates are included in Microsoft’s Root Store, meaning applications running on Windows as well as Microsoft’s Internet Explorer web browser would have trusted the bogus NIC certificates. Google said that Chrome users on Windows would not have been victims of the […]

Microsoft Uses Courts To Take Down Malicious, Managed DNS Services

Microsoft Corp. has taken action against yet another cyber crime network, taking control of- and shutting down a managed DNS (domain name system) operated by the firm No-IP that were being abused by cyber criminals, the company said on Monday.   The domains were associated with malware families named Jenxcus and Bladabindi that are believed to have infected on some 7.5 million systems, globally. The malicious programs – which are used to spy on the operators of infected systems – use Dynamic DNS services like NO-IP to communicate with command and control systems used to manage infected systems. Dynamic DNS makes the malicious systems more difficult to trace. In a post on Microsoft’s Digital Crimes Unit blog, Richard Domingues Boscovich, the company’s Assistant General Counsel said that the company had filed a civil case on June 19 naming two foreign nationals: Mohamed Benabdellah and Naser Al Mutairi along with a U.S. company, Vitalwerks Internet Solutions, LLC (doing […]

DHS Warns Energy Firms Of Malware Used In Targeted Attacks

The Department of Homeland Security warned firms in the energy sector about new, targeted malware infecting industrial control systems and stealing data. DHS’s ICS CERT, the Industrial Control Systems Computer Emergency Response Team, said it is analyzing malware associated with an ICS-focused malware campaign. The malicious software, dubbed “Havex” that was being spread by way of phishing emails and so-called “watering hole” attacks that involved compromises of ICS vendor web sites. DHS was alerted to the attacks by researchers at the security firms Symantec (which dubbed the malware campaign “Dragonfly”) and F-Secure (“Havex”) -a remote access trojan (or RAT) that also acts as an installer (or “downloader”) – fetching other malicious applications to perform specific tasks on compromised networks. One of those additional payloads is a Trojan Horse program dubbed Karagany (by Symantec) that has been liked to prior attacks on energy firms. According to Symantec, the malware targeted energy grid operators, major electricity generation firms, […]
