A previously undocumented Go-based malware is targeting Redis servers with the goal of taking control of the infected systems and likely building a botnet network. The attacks involve taking advantage of a critical security vulnerability in the open source, in-memory, key-value store that was disclosed earlier this year to deploy  Redigo , according to cloud security firm  Aqua . Tracked as CVE-2022-0543 (CVSS score: 10.0), the weakness pertains to a case of sandbox escape in the Lua scripting engine that could be leveraged to attain remote code execution. This is not the first time the flaw has come under active exploitation, what with Juniper Threat Labs uncovering attacks perpetrated by the  Muhstik botnet  in March 2022 to execute arbitrary commands. The Redigo infection chain is similar in that the adversaries scan for exposed Redis servers on port 6379 to establish initial access, following it up by downloading a shared library "exp_lin.so" from a remote server.

An ongoing analysis into an up-and-coming cryptocurrency mining botnet known as  KmsdBot  has led to it being accidentally taken down. KmsdBot, as christened by the Akamai Security Intelligence Response Team (SIRT), came to light mid-November 2022 for its ability to  brute-force systems  with weak SSH credentials. The botnet strikes both Windows and Linux devices spanning a wide range of microarchitectures with the primary goal of deploying mining software and corralling the compromised hosts into a DDoS bot. Some of the major targets included gaming firms, technology companies, and luxury car manufacturers. Akamai researcher Larry W. Cashdollar, in a new update, explained how commands sent to the bot to understand its functionality in a controlled environment inadvertently neutralized the malware. "Interestingly, after one single improperly formatted command, the bot stopped sending commands," Cashdollar  said . "It's not every day you come across a botnet t

For 6 months, the infamous Emotet botnet has shown almost no activity, and now it's distributing malicious spam. Let's dive into details and discuss all you need to know about the notorious malware to combat it. Why is everyone scared of Emotet? Emotet  is by far one of the most dangerous trojans ever created. The malware became a very destructive program as it grew in scale and sophistication. The victim can be anyone from corporate to private users exposed to spam email campaigns. The botnet distributes through phishing containing malicious Excel or Word documents. When users open these documents and enable macros, the Emotet DLL downloads and then loads into memory. It searches for email addresses and steals them for spam campaigns. Moreover, the botnet drops additional payloads, such as Cobalt Strike or other attacks that lead to ransomware. The polymorphic nature of Emotet, along with the many modules it includes, makes the malware challenging to identify. The Emotet

Microsoft on Tuesday disclosed the intrusion activity aimed at Indian power grid entities earlier this year likely involved the exploitation of security flaws in a now-discontinued web server called Boa . The tech behemoth's cybersecurity division  said  the vulnerable component poses a "supply chain risk that may affect millions of organizations and devices." The findings build on a prior report  published  by Recorded Future in April 2022, which delved into a sustained campaign orchestrated by suspected China-linked adversaries to strike critical infrastructure organizations in India. The cybersecurity firm attributed the attacks to a previously undocumented threat cluster called Threat Activity Group 38. While the Indian government described the attacks as unsuccessful "probing attempts," China denied it was behind the campaign. The connections to China stem from the use of a modular backdoor dubbed  ShadowPad , which is known to be shared among several

Google has won a lawsuit filed against two Russian nationals in connection with the operation of a botnet called Glupteba , the company  said  last week. The U.S. District Court for the Southern District of New York imposed monetary sanctions against the defendants and their U.S.-based legal counsel. The defendants have also been asked to pay Google's attorney fees. The defendants' move to press sanctions against Google was denied. The development comes nearly a year after the tech giant  took down  the malware's command-and-control infrastructure and initiated legal proceedings against Dmitry Starovikov and Alexander Filippov , who are said to have been in charge of running the illegal botnet. The defendants, along with 15 others, have also been accused of using the malware to create a hacked network of devices to mine cryptocurrencies, harvest victims' personal and financial data, and place disruptive ads. Gluteba is distinguished from its botnet counterparts b
