Figure 1: How an LDAP reflection-amplification attack works LDAP’s Weak Spot LDAP is used to query resources such as networks, systems, applications, and services throughout an organization network. This protocol is typically served over TCP, which requires a connection to be established before data is transferred. But, in this case, because the source IP address…
Read MoreTrickbot, the latest arrival to the banking malware scene and successor to the infamous Dyre botnet, is in constant flux, and its authors are continually adding new targets and functionality. F5 malware researchers have been monitoring Trickbot and have uncovered a new variant that substantially increases the number of German banks being targeted. Trickbot was…
Read MoreSo far, we’ve seen IoT Distributed Denial-of-Service (DDoS) attacks on a Death Star scale. Even if your organization wasn’t a direct target of these giant barrages, many others were caught up as collateral damage because they had services adjacent or dependent on the direct target. Because of this, many organizations are preparing or strengthening their…
Read MoreIn just four short years, a healthy dose of paranoia about individual privacy as well as emerging support for encryption by browsers, social media sites, webmail, and SaaS applications have pushed encryption estimates from almost non-existent (in the low single digits before 2013) to just over 50% by the end of 2016. That’s quite a…
Read MoreCyber security has evolved in ways we never could have imagined. We have more specialized and powerful tools and services today than ever before, security budgets are slowly inching upward, and there are even glimmers of support from management. Yet, with the pace of technological change, the growing “professionalization” of cyber crime, and ever…

Read MoreThe essence of this attack is van Beek’s Microsoft Exchange Autodiscover vulnerability. In a September 2016 interview with The Register, van Beek said, “I recently discovered that most, if not all, Microsoft Exchange clients (eg, Outlook, iPhone mail app, Android mail app, Blackberry Mail App) are more than happy to provide a user’s password in plain…
Read MoreMalware that steals banking credentials is still one of today’s most lucrative cybercrime schemes. It’s not unusual for a banking Trojan to evolve over the years, and Ramnit is a perfect example. It was active for several years until it was disrupted in early 2015 by Europol working with several tech companies. It resurfaced in…
Read MoreBut 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…
