Hackers have commandeered approximately three million smart toothbrushes, transforming them into a botnet for launching a DDoS (Distributed Denial of Service) attack against a Swiss company's website, causing significant financial losses. more
The attack began Tuesday afternoon, and continued for two days straight, according to a source close to Russia’s Central Bank quoted by RIA Novosti. Sberbank confirmed the DDoS attack on its online services. more
Throughout the second half of 2012 many security folks have been asking "how much is a zero-day vulnerability worth?" and it's often been hard to believe the numbers that have been (and continue to be) thrown around. For the sake of clarity though, I do believe that it's the wrong question... the correct question should be "how much do people pay for working exploits against zero-day vulnerabilities?" more
The United States in retaliation to the growing Iranian cyber-activity and the shooting of an unarmed US drone last week has launched a series of cyberattacks against Iran's military IT systems. more
The majority of network breaches begin and end with the installation of malware upon a vulnerable device. For the rest, once that initial malware beachhead has been achieved, the story is only just beginning. The breach disclosures that make the news are often confusing as they're frequently compiled from third-hand reports, opinions and technical assumptions. More often than not, they include a discussion about the malware - how advanced it was, etc. - and whether any 0-day vulnerabilities were likely used by the mysterious attacker. more
This year in July gen. Keith Alexander, director of the National Security Agency and head of the US Cyber Command participated at DefCon, the hackers conference in Las Vegas. In his address, gen. Alexander said, among other things, "This is the world's best cybersecurity community. In this room right here is the talent our nation needs to secure cyberspace."... As someone, who is regularly meeting the top Russian cyber folks, I already know (unofficially, of course) how the words of gen. Alexander were met in Moscow. more
You have just a couple of days to either complete a survey or submit a paper to join the "Coordinating Attack Response at Internet Scale (CARIS)" Workshop happening on June 19, 2015, in Berlin, Germany... If you are interested in helping improve the overall security and resilience of the Internet through increased communication between the groups responding to the large-scale attacks happening on the Internet every day, I would strongly encourage you to apply! more
The market has failed to secure cyberspace. A ten-year experiment in faith-based cybersecurity has proven this beyond question. The market has failed and the failure of U.S. policies to recognize this explains why we are in crisis. The former chairman of the Security and Exchange Commission, Christopher Cox, a longtime proponent of deregulation, provided a useful summary of the issue when he said, "The last six months have made it abundantly clear that voluntary regulation does not work."... more
If current predictions are correct, 2009 will be a tougher year than 2008 in terms of the economy. In tough economic times such as these it becomes increasingly important for us to follow recommended safety practices when going online. As the numbers of Internet-related fraud and financial scams continue to increase we should expect the current economic situation to produce more victims of cybercrime. Knowledge and vigilance are the keys to remaining safe while online. more
Foreign diplomats based in Belarus have been under the digital crosshairs of hackers with suspected ties to the Belarusian government for nearly a decade, security researchers revealed on Thursday. more
In a study published in the JAMA Network, evidence indicates that ransomware attacks on healthcare delivery organizations (HDOs) lead to substantial disruptions in patient care and emergency department workflows. more
I don't (and probably won't) have anything substantive to say about the technical details of the just-announced Meltdown and Spectre attacks. What I do want to stress is that these show, yet again, that security is a systems property: being secure requires that every component, including ones you've never heard of, be secure. These attacks depend on hardware features... and no, many computer programmers don't know what those are, either. more
A weakness in modern computers allows attackers to steal encryption keys and other sensitive information, according to the latest discovery by cybersecurity firm F-Secure. more
In October 2012, the Chairman and Ranking Member of the House Intelligence Committee issued a joint statement warning American companies that were doing business with the large Chinese telecommunications companies Huawei and ZTE to "use another vendor." The bipartisan statement explains that the Intelligence Committee's Report, "highlights the interconnectivity of U.S. critical infrastructure systems and warns of the heightened threat of cyber espionage and predatory disruption or destruction of U.S. networks if telecommunications networks are built by companies with known ties to the Chinese state, a country known to aggressively steal valuable trade secrets and other sensitive data from American companies." more
The 2010 version of the now-annual Messaging Anti-abuse Working Group (MAAWG) 'Email Security Awareness and Usage Report' was released yesterday. While un-belied by the title, the vernacular name might get a bit more attention: "The MAAWG Consumer Email Survey". ... Consumers were surveyed in North America and across Europe with variety of questions from computer expertise and savvy, to their preferences of email. more
