But that’s not the worst news coming out of this survey. No, not by any stretch of the imagination is that the bad news. Sit down and strap in, because it gets much worse. In spite of pushing vulnerable applications into production (and into the hands of consumers), a staggering 44% admitted they aren’t doing anything to…
Read More“Managing” vulnerabilities is an endless effort that is only truly noticed when it fails. More often than not, the constant debate over which vulnerabilities get prioritized for remediation is decided based on likelihood of exploit, followed by impact, and level of effort to fix. The typical result is that low- and medium-grade vulnerabilities get de-prioritized—in…
Read MoreNo matter how application-savvy you are, it should be fairly obvious that this is not a typical Content-Type header for an HTTP request. According to the RFC, Content-Type is usually of the form “type/subtype”7. This leviathan contains a valid Content-Type header in the very first line—multipart/form-data—but even a rudimentary BNF parser would flag this as a…
Read MoreFigure 1: CVE-2017-5638 campaign The exploit triggers the vulnerability via the Content-Type header value, which the attacker customized with shell commands to be executed if the server is vulnerable. In the first days of this campaign, shell commands were observed to infect the machine with the “PowerBot” malware, which is written in PERL, and uses…
Read MoreThese notifications give defenders a chance to prepare their response. Without them, a hacktivist runs the risk of the affected organization attributing the attack to criminals or equipment outages. For a hacktivist, that’s a fail—the attention is just as important to them as the shutdown. The real problem with hacktivists perpetrating DoS attacks is the…
Read MoreI was chatting recently with a coworker who had just returned from a DevOpsy-focused conference. She mentioned she had met a woman whose entire role was focused on finding “lost” cloud instances (that is, virtual servers running in a public or private cloud network). Her entire job is just to find those instances and get…
Read More2016 has been called “the year of stolen credentials,” and with good reason. Between the massive breaches at Yahoo, LinkedIn, MySpace, Tumblr,1 Twitter,2 and Dropbox,3 just to name a few, it’s estimated that over 2 billion records were stolen. Although attackers steal all kinds of data, a vast majority of what’s stolen are user credentials,…
Read MoreAll businesses watch their bottom line. That’s unsurprising. Those that provide technology to consumers (whether IoT device manufacturers or your local ISP that provides your home router) are particularly careful about balancing product support with ease of use. That can lead to what the inventors no doubt believe is an ingenious method of determining passwords…
Read MoreIt’s been another banner year for leakers. In May, Wikileaks released the CIA’s Vault7 cyberwarfare documentation,1 and the Shadow Brokers released NSA exploit information, including the Windows EternalBlue2 exploit. EternalBlue was quickly weaponized into the WannaCry ransomware that pummeled the Internet for days. The Petya/NotPetya ransomware hitting Eastern Europe is also reportedly using EternalBlue to infect machines.…
Read MoreThese hackers lived where the bending and breaking of the rules was just a part of the culture. Both men were astonished at how Americans obeyed traffic rules and smoking restrictions, citing how in their country such rules are ignored. They wanted to go into business for themselves but found it difficult to do so.…
