This year, it seems like you can hardly turn around without bumping into some commentary on a breach. There’s expert analysis on every blog. The trade press eats up controversy stirred up by responses. Twitter trends. My inbox fills up with quotes and offers to hear more about the breach. It’s all bad news, so…
Read MoreWhen it comes to crossing the US border, we used to worry about the simple things—too many souvenirs to avoid paying import duties, lines short enough to get to a bathroom in a reasonable timeframe, maybe concerns about which fruits and vegetables could be kept from the last grocery run. Today, we’ve got one more…
Read MoreI recently had the opportunity to sit down with two of F5’s top threat researchers, Sara Boddy and Justin Shattuck, to pick their brains about IoT, its current state of “security,” and what we can expect to see in terms of threats, attacks, and mitigations in the future. Justin and Sara are co-authors of three IoT threat research…
Read MoreThis isn’t your mama’s botnet. This is a proper botnet. If you were the world’s best IoT botnet builder and you wanted to show the world how well-crafted an IoT botnet could be, Reaper is what you’d build. It hasn’t been seen attacking anyone yet, and that is part of its charm. But, what is…
Read MoreSo, what’s the issue when it comes to encryption and quantum computing? Today’s asymmetric encryption algorithms, which are primarily used for key exchanges and digital signatures, are considered vulnerable to quantum computers. For example, using today’s traditional, digital, transistor-based computers, it’s estimated it would take 6 quadrillion CPU years to crack a 2048-bit RSA decryption key.7 But,…
Read MoreEmail Headers An excellent source of internal configuration information can be gleaned from email headers. Attackers can simply fire off a few email inquiries to folks at an organization and see what they can find. Here’s a typical email header using our example company, Boring Aeroplanes, from our phishing example. Note both internal and…
Read MoreSome startups see security as a nice-to-have that can be added months or years after launch. The smart ones realize that dependable security from the beginning means solid performance, satisfied customers, and no precious startup dollars wasted on fraud or incidents. F5 Labs decided to peek under the hood of one of these smart startups: Wanderlust…
Read MoreWe also analyzed the primary root causes of the breaches, how that varied in breach remediation costs by industry, and the impact of these breaches on each data type breached on the global scale. The purpose of our analysis was to identify where organizations are most likely to be attacked in a way that…
Read MoreF5 threat researchers have discovered a new Apache Struts campaign. This new campaign is a sophisticated multi-staged attack targeting internal networks with the NSA-attributed EternalBlue and EternalSynergy exploits. We have dubbed the campaign “Zealot” based on the name of the zip file containing the python scripts with the NSA-attributed exploits. As we continue to research…
Read MoreEighty-six percent of Internet hosts prefer forward secrecy; all modern browsers do, too. The Bleichenbacher attack only affects RSA sessions not protected with the ephemeral keys offered by forward secrecy. All modern browsers and mobile clients have preferred ephemeral keys for several years. Google has been preferring them with their servers and software since 2012.6…
