Rust-Based P2PInfect Botnet Evolves with Miner and Ransomware Payloads

Rust-Based P2PInfect Botnet Evolves with Miner and Ransomware Payloads

Jun 27, 2024 Cryptojacking / Data Protection
The peer-to-peer malware botnet known as P2PInfect has been found targeting misconfigured Redis servers with ransomware and cryptocurrency miners. The development marks the threat's transition from what appeared to be a dormant botnet with unclear motives to a financially motivated operation. "With its latest updates to the crypto miner, ransomware payload, and rootkit elements, it demonstrates the malware author's continued efforts into profiting off their illicit access and spreading the network further, as it continues to worm across the internet," Cado Security said in a report published this week. P2PInfect came to light nearly a year ago, and has since received updates to target MIPS and ARM architectures. Earlier this January, Nozomi Networks uncovered the use of the malware to deliver miner payloads. It typically spreads by targeting Redis servers and its replication feature to transform victim systems into a follower node of the attacker-controlled server...
New Migo Malware Targeting Redis Servers for Cryptocurrency Mining

New Migo Malware Targeting Redis Servers for Cryptocurrency Mining

Feb 20, 2024 Server Security / Cryptojacking
A novel malware campaign has been observed targeting Redis servers for initial access with the ultimate goal of mining cryptocurrency on compromised Linux hosts. "This particular campaign involves the use of a number of novel system weakening techniques against the data store itself," Cado security researcher Matt Muir  said  in a technical report. The cryptojacking attack is facilitated by a malware codenamed Migo, a Golang ELF binary that comes fitted with compile-time obfuscation and the ability to persist on Linux machines. The cloud security company said it detected the campaign after it identified an "unusual series of commands" targeting its Redis honeypots that are engineered to lower security defenses by disabling the following configuration options - protected-mode   replica-read-only aof-rewrite-incremental-fsync , and rdb-save-incremental-fsync It's suspected that these options are turned off in order to send additional commands to the Re...

HeadCrab 2.0 Goes Fileless, Targeting Redis Servers for Crypto Mining

HeadCrab 2.0 Goes Fileless, Targeting Redis Servers for Crypto Mining

Feb 01, 2024 Cryptocurrency / Botnet
Cybersecurity researchers have detailed an updated version of the malware  HeadCrab  that's known to target Redis database servers across the world since early September 2021. The development, which comes exactly a year after the malware was first  publicly disclosed  by Aqua, is a sign that the financially-motivated threat actor behind the campaign is actively adapting and refining their tactics and techniques to stay ahead of the detection curve. The cloud security firm  said  that "the campaign has almost doubled the number of infected Redis servers," with an additional 1,100 compromised servers, up from 1,200 reported at the start of 2023. HeadCrab is designed to infiltrate internet-exposed Redis servers and wrangle them into a botnet for illicitly mining cryptocurrency, while also leveraging the access in a manner that allows the threat actor to execute shell commands, load fileless kernel modules, and exfiltrate data to a remote server. While th...

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices

New P2PInfect Botnet MIPS Variant Targeting Routers and IoT Devices

Dec 04, 2023 Malware / Botnet
Cybersecurity researchers have discovered a new variant of an emerging botnet called  P2PInfect  that's capable of targeting routers and IoT devices. The latest version, per Cado Security Labs, is compiled for Microprocessor without Interlocked Pipelined Stages ( MIPS ) architecture, broadening its capabilities and reach. "It's highly likely that by targeting MIPS, the P2PInfect developers intend to infect routers and IoT devices with the malware," security researcher Matt Muir  said  in a report shared with The Hacker News. P2PInfect, a Rust-based malware, was  first   disclosed  back in July 2023, targeting unpatched Redis instances by exploiting a critical Lua sandbox escape vulnerability ( CVE-2022-0543 , CVSS score: 10.0) for initial access. A subsequent analysis from the cloud security firm in September  revealed  a surge in P2PInfect activity, coinciding with the release of iterative variants of the malware. The new artifacts, b...
New SkidMap Linux Malware Variant Targeting Vulnerable Redis Servers

New SkidMap Linux Malware Variant Targeting Vulnerable Redis Servers

Aug 07, 2023 Data Security / Linux
Vulnerable  Redis services  have been targeted by a "new, improved, dangerous" variant of a malware called SkidMap that's engineered to target a wide range of Linux distributions. "The malicious nature of this malware is to adapt to the system on which it is executed," Trustwave security researcher Radoslaw Zdonczyk  said  in an analysis published last week. Some of the Linux distribution SkidMap sets its eyes on include Alibaba, Anolis, openEuler, EulerOS, Stream, CentOS, RedHat, and Rocky. SkidMap was  first disclosed  by Trend Micro in September 2019 as a cryptocurrency mining botnet with capabilities to load malicious kernel modules that can obfuscate its activities as well as monitor the miner process. The operators of the malware have also been found camouflaging their backup command-and-control (C2) IP address on the Bitcoin blockchain, evocative of another botnet malware known as  Glupteba . "The technique of fetching real-time data from...
New P2PInfect Worm Targets Redis Servers with Undocumented Breach Methods

New P2PInfect Worm Targets Redis Servers with Undocumented Breach Methods

Jul 31, 2023 Cyber Threat / Botnet
The P2PInfect peer-to-peer (P2) worm has been observed employing previously undocumented initial access methods to breach susceptible Redis servers and rope them into a botnet. "The malware compromises exposed instances of the Redis data store by exploiting the replication feature," Cado Security researchers Nate Bill and Matt Muir  said  in a report shared with The Hacker News. "A common attack pattern against Redis in cloud environments is to exploit this feature using a malicious instance to enable replication. This is achieved via connecting to an exposed Redis instance and issuing the SLAVEOF command." The Rust-based malware was  first documented  by Palo Alto Networks Unit 42, calling out the malware's ability to exploit a critical Lua sandbox escape vulnerability ( CVE-2022-0543 , CVSS score: 10.0) to obtain a foothold into Redis instances. The campaign is believed to have commenced on or after June 29, 2023. However, the latest discovery suggests th...
OpenAI Reveals Redis Bug Behind ChatGPT User Data Exposure Incident

OpenAI Reveals Redis Bug Behind ChatGPT User Data Exposure Incident

Mar 25, 2023 Artificial Intelligence / Data Security
OpenAI on Friday disclosed that a bug in the Redis open source library was responsible for the exposure of other users' personal information and chat titles in the upstart's ChatGPT service earlier this week. The  glitch , which came to light on March 20, 2023, enabled certain users to view brief descriptions of other users' conversations from the chat history sidebar, prompting the company to temporarily shut down the chatbot. "It's also possible that the first message of a newly-created conversation was visible in someone else's chat history if both users were active around the same time," the company  said . The bug, it further added, originated in the  redis-py library , leading to a scenario where canceled requests could cause connections to be corrupted and return unexpected data from the database cache, in this case, information belonging to an unrelated user. To make matters worse, the San Francisco-based AI research company said it introduce...
New Cryptojacking Campaign Leverages Misconfigured Redis Database Servers

New Cryptojacking Campaign Leverages Misconfigured Redis Database Servers

Mar 02, 2023 Data Security / Cryptojacking
Misconfigured Redis database servers are the target of a novel cryptojacking campaign that leverages a legitimate and open source command-line file transfer service to implement its attack. "Underpinning this campaign was the use of transfer[.]sh," Cado Security  said  in a report shared with The Hacker News. "It's possible that it's an attempt at evading detections based on other common code hosting domains (such as pastebin[.]com)." The cloud cybersecurity firm said the command line interactivity associated with transfer[.]sh has made it an ideal tool for hosting and delivering malicious payloads. The attack chain commences with targeting insecure Redis deployments, followed by registering a  cron job  that leads to arbitrary code execution when parsed by the scheduler. The job is designed to retrieve a payload hosted at transfer[.]sh. It's worth noting that  similar   attack mechanisms  have been employed by other threat actors like TeamTNT an...

New Threat: Stealthy HeadCrab Malware Compromised Over 1,200 Redis Servers

Feb 02, 2023 Database Security / Cryptocurrency
At least 1,200 Redis database servers worldwide have been corralled into a botnet using an "elusive and severe threat" dubbed HeadCrab since early September 2021. "This advanced threat actor utilizes a state-of-the-art, custom-made malware that is undetectable by agentless and traditional anti-virus solutions to compromise a large number of Redis servers," Aqua security researcher Asaf Eitani  said  in a Wednesday report. A significant concentration of infections has been recorded in China, Malaysia, India, Germany, the U.K., and the U.S. to date. The origins of the threat actor are presently unknown. The findings come two months after the cloud security firm shed light on a Go-based malware codenamed  Redigo  that has been found compromising Redis servers. The attack is designed to target Redis servers that are exposed to the internet, followed by issuing a  SLAVEOF command  from another Redis server that's already under the adversary's control. In...
Hackers Exploiting Redis Vulnerability to Deploy New Redigo Malware on Servers

Hackers Exploiting Redis Vulnerability to Deploy New Redigo Malware on Servers

Dec 02, 2022 Database Security / Cyber Threat
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...
