Microsoft has confirmed that the active exploitation of PaperCut servers is linked to attacks that are designed to deliver Cl0p and LockBit ransomware families. The tech giant’s threat intelligence team is attributing a subset of the intrusions to a financially motivated actor it tracks under the name Lace Tempest (formerly DEV-0950), which overlaps with other […]
A novel credential-stealing malware called Zaraza bot is being offered for sale on Telegram while also using the popular messaging service as a command-and-control (C2). “Zaraza bot targets a large number of web browsers and is being actively distributed on a Russian Telegram hacker channel popular with threat actors,” cybersecurity company Uptycs said in a […]
Critical security flaws in Cacti, Realtek, and IBM Aspera Faspex are being exploited by various threat actors in hacks targeting unpatched systems. This entails the abuse of CVE-2022-46169 (CVSS score: 9.8) and CVE-2021-35394 (CVSS score: 9.8) to deliver MooBot and ShellBot (aka PerlBot), Fortinet FortiGuard Labs said in a report published this week. CVE-2022-46169 relates […]
A new Golang-based malware dubbed GoBruteforcer has been found targeting web servers running phpMyAdmin, MySQL, FTP, and Postgres to corral the devices into a botnet. “GoBruteforcer chose a Classless Inter-Domain Routing (CIDR) block for scanning the network during the attack, and it targeted all IP addresses within that CIDR range,” Palo Alto Networks Unit 42 […]
A sophisticated botnet known as MyloBot has compromised thousands of systems, with most of them located in India, the U.S., Indonesia, and Iran. That’s according to new findings from BitSight, which said it’s “currently seeing more than 50,000 unique infected systems every day,” down from a high of 250,000 unique hosts in 2020. Furthermore, an […]
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 […]
The Zerobot DDoS botnet has received substantial updates that expand on its ability to target more internet-connected devices and scale its network. Microsoft Threat Intelligence Center (MSTIC) is tracking the ongoing threat under the moniker DEV-1061, its designation for unknown, emerging, or developing activity clusters. Zerobot, first documented by Fortinet FortiGuard Labs earlier this month, […]
An ongoing analysis of the KmsdBot botnet has raised the possibility that it’s a DDoS-for-hire service offered to other threat actors. This is based on the different industries and geographies that were attacked, web infrastructure company Akamai said. Among the notable targets included FiveM and RedM, which are game modifications for Grand Theft Auto V […]
The operators of the Glupteba botnet resurfaced in June 2022 as part of a renewed and “upscaled” campaign, months after Google disrupted the malicious activity. The ongoing attack is suggestive of the malware’s resilience in the face of takedowns, cybersecurity company Nozomi Networks said in a write-up. “In addition, there was a tenfold increase in […]
A novel Go-based botnet called Zerobot has been observed in the wild proliferating by taking advantage of nearly two dozen security vulnerabilities in the internet of things (IoT) devices and other software. The botnet “contains several modules, including self-replication, attacks for different protocols, and self-propagation,” Fortinet FortiGuard Labs researcher Cara Lin said. “It also communicates […]
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 […]
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 […]
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 […]
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 […]
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 […]
The threat actor behind the Fodcha distributed denial-of-service (DDoS) botnet has resurfaced with new capabilities, researchers reveal. This includes changes to its communication protocol and the ability to extort cryptocurrency payments in exchange for stopping the DDoS attack against a target, Qihoo 360’s Network Security Research Lab said in a report published last week. Fodcha […]
The notorious Emotet botnet has been linked to a new wave of malspam campaigns that take advantage of password-protected archive files to drop CoinMiner and Quasar RAT on compromised systems. In an attack chain detected by Trustwave SpiderLabs researchers, an invoice-themed ZIP file lure was found to contain a nested self-extracting (SFX) archive, the first […]
Web infrastructure and security company Cloudflare disclosed this week that it halted a 2.5 Tbps distributed denial-of-service (DDoS) attack launched by a Mirai botnet. Characterizing it as a “multi-vector attack consisting of UDP and TCP floods,” researcher Omer Yoachimik said the DDoS attack targeted the Minecraft server Wynncraft in Q3 2022. “The entire 2.5 Tbps […]
The Emotet malware is now being leveraged by ransomware-as-a-service (RaaS) groups, including Quantum and BlackCat, after Conti’s official retirement from the threat landscape this year. Emotet started off as a banking trojan in 2014, but updates added to it over time have transformed the malware into a highly potent threat that’s capable of downloading other […]
A variant of the Mirai botnet known as MooBot is co-opting vulnerable D-Link devices into an army of denial-of-service bots by taking advantage of multiple exploits. “If the devices are compromised, they will be fully controlled by attackers, who could utilize those devices to conduct further attacks such as distributed denial-of-service (DDoS) attacks,” Palo Alto […]
A new botnet named Orchard has been observed using Bitcoin creator Satoshi Nakamoto’s account transaction information to generate domain names to conceal its command-and-control (C2) infrastructure. “Because of the uncertainty of Bitcoin transactions, this technique is more unpredictable than using the common time-generated [domain generation algorithms], and thus more difficult to defend against,” researchers from […]
