F5 threat researchers detected attackers actively exploiting the rTorrent client through a previously undisclosed misconfiguration vulnerability and deploying a Monero (XMR) crypto-miner operation. The rTorrent client misconfiguration vulnerabilities include: No authentication required for XML-RPC communication Sensitive XML-RPC method is allowed (direct OS command execution) Attackers are actively exploiting this vulnerability in the wild by scanning…
Read MoreLast week, F5 threat researchers spotted a Monero (XMR) crypto-mining campaign that was taking advantage of a user configuration vulnerability in the rTorrent client, specifically misconfigured XML-RPC functionality. This misconfiguration vulnerability in rTorrent allows an unauthenticated user to execute methods in the rTorrent client using HTTP requests. After deeper analysis of the attack logs, F5…
Read MoreThankfully, this alert was a mistake and there was no real danger, but the incident raises a far broader question: how many of our critical systems are this vulnerable to human error, poor software design, and insufficient security controls, all of which were factors in the HIEMA incident? Many of the real-world systems we depend…
Read MoreIt’s a sad state of Internet affairs when the US government must publish a US-CERT Alert about Russia targeting US entities through negligent network infrastructure misconfigurations.1 In Alert TA18-106A, US-CERT discloses that since 2015, the US government, in partnership with the UK, has been receiving data from numerous sources that “large numbers” of enterprise-class and…
Read MoreThe rise of poorly secured Internet of Things (IoT) devices has made it possible for attackers to gain access to targets of interest. Nation-states, spies, mercenaries, and others don’t need to dress up as repairmen to plant bugs in rooms anymore; they can just hack into a room that has vulnerable IoT devices. In May,…
Read MoreExecutive Summary Like coral reefs teeming with a variety of life, web applications are “colony creatures.” They consist of a multitude of independent components, running in separate environments with different operational requirements and supporting infrastructure (both in the cloud and on premises) glued together across networks. In this report, we examine that series of interacting…
Read MoreEver wonder what security professionals see as their main barrier to achieving a strong application security posture? We wondered that, too, so we asked them. As part of F5 Labs’ first annual Application Protection Report, F5, in conjunction with Ponemon Institute, surveyed security professionals on a slew of security-related topics. In answer to this particular…
Read MoreAttack Destination Ports The following ports in order of prevalence were targeted in the Singapore attacks: 5060 — clear text Session Initiation Protocol (SIP) 23 — Telnet remote management 1433 — Microsoft SQL Server database 81 — Alternate web server port for host-to-host communication 7547 — TCP port used by ISPs to remotely manage…
Read MoreIn July 2018, F5 released its first annual Application Protection Report based on the results of an F5-commissioned Ponemon survey of 3,135 IT and security practitioners across the globe. Additional research conducted by Whatcom Community College, University of Washington Tacoma, along with data from White Hat Security and Loryka served to make this one of…
Read MoreBackSwap is new banking malware recently discovered by Eset1 and later analyzed by CERT Polska.2 Unlike previous banking trojans, which typically either intercept requests and redirect users to fake banking websites or inject malicious code from command and control (C&C) servers to manipulate browser processes, BackSwap keeps its campaign locally. The JavaScript is hardcoded and…
