Month: April 2024
In 2018 we published our first Application Protection Report, which summarized trends and attack patterns for 2017 across multiple disciplines of information security and offered a big picture strategy for controlling application risk. We created that report in order to provide three things that we felt the security industry needs: a specific focus on application…
Read MoreTo both understand and keep pace with evolving cybercriminal mindsets, many businesses are fighting fire with fire – in other words hiring hackers for help. In fact, large corporations such as Airbnb, PayPal and Spotify, recently revealed that they have willingly spent over £38M on ethical hackers to tighten their cyber defences and avoid crippling…
Read MoreCryptominers are frequently included in recent attack campaigns; if you would like to learn more about cryptominers, please check out some of our previous monthly attack campaign wrap-ups. Conclusion Campaigns aimed at mining cryptocurrency and targeting Oracle WebLogic continue to rise in popularity. This has been fueled in part by the zero-day vulnerability found in…
Read MorePoor security is another clue that young novices are operating botnets. The Owari authors left their command and control (C&C) MySQL database wide open (port 3306), “protected” with both the username and password of “root.” Control of IoT devices is a highly competitive market, where rivals commonly DDoS each other. In one case, a competing…
Read MoreAs the Chief Information Security Officer at F5, it is my pleasure to welcome you to F5 Labs’ CISO to CISO section. This is an arena for frank and transparent discussions on all aspects of running an information security program. We’ll discuss topics like technical guidance on mitigating specific risks, as well as broader perspectives…
Read MoreIn-App Testing Since the HSTS and HPKP protocols allow for genuine interception of SSL by trusted certificates, nothing can be done to warn end users that their communications are being intercepted. For those that need to inform their users of interception, in-app testing could be considered. By performing an additional SSL/TLS handshake, using Javascript within…
Read MoreConclusion Campaigns aimed at mining cryptocurrency and targeting Oracle WebLogic are clearly on the rise, and F5 researchers anticipate this trend to continue. This has been fueled partly by the zero-day vulnerability (CVE-2019-2725)found in April 2019. Oracle WebLogic is used widely by large corporations, and the servers are resource-intensive. This attracts threat actors looking to…
Read MoreThen there are the technical questions that need to be answered. What data will be captured, shared, and processed? What mobile platforms will the app run on? What server-side platforms will it need to talk to? Internal platforms? Third-party services? You also need to dig into the questions of expectations and dependencies. How important will…
Read MoreAPI Vulnerability Data The sensor network that our partner Lorkya maintains found only 0.1% of attack traffic was definitively looking for API vulnerabilities. However, this is probably better attributed to the limitations of the sensor network than any trends about API attacks. Loryka’s sensors primarily detect wide-ranging probes and reconnaissance campaigns where attackers are looking…
Read MoreThe next step in this process is to convert the decrypted and decompressed data file from binary into a human readable format. The following python snippet provides a regular expression that will roughly split the injects from one another: import re regex_res = re.split(‘[x00]{1}[x00-xff]{7}[x00]{2}[x01-xff]{1}’, data[7:]) The steps outlined here can be used on the different…
