With more households running smart devices that access the internet, the router is typically their only doorkeeper. And whether an end user has a laptop/desktop and router combo, or a miscellany of other devices connected to the network, the security risks are the same. Based on our research, home routers have been most susceptible to cross-site scripting (XSS) and PHP arbitrary code injection attacks, as well as being involved in carrying out DNS amplification attacks.Read More
By Miguel Carlo Ang and Earle Maui Earnshaw We recently saw a malicious spam campaign that has AutoIT-compiled payloads – the trojan spy Negasteal or Agent Tesla (detected by Trend Micro as TrojanSpy.Win32.NEGASTEAL.DOCGC), and remote access trojan (RAT) Ave Maria or Warzone (TrojanSpy.Win32.AVEMARIA.T) – in our honeypots. The upgrading of payloads from a typical trojan…Read More
By Augusto Remillano II and Jakub Urbanec Within a span of three weeks, our telemetry uncovered three notable malware variants of Neko, Mirai, and Bashlite. On July 22, 2019, we saw and started analyzing a Neko botnet sample, then observed another sample with additional exploits the following week. A Mirai variant that calls itself “Asher”…Read More
We discovered a new variant of Mirai that uses a total of 13 different exploits, almost all of which have been used in previous Mirai-related attacks. Typical of Mirai variants, it has backdoor and distributed denial-of-service (DDoS) capabilities. However, this case stands out as the first to have used all 13 exploits together in a single campaignRead More
Many devices such as cameras, printers, and routers use UPnP to make it easy for them to automatically discover and vet other devices on a local network and communicate with each other for data sharing or media streaming. UPnP works with network protocols to configure communications in the network. But with its convenience comes security holes that range from attackers gaining control of devices to bypassing firewall protections.
We looked into UPnP-related events in home networks and found that many users still have UPnP enabled in their devices.Read More
