DirtyMoe Malware Infects 2,000+ Ukrainian Computers for DDoS and Cryptojacking

DirtyMoe Malware Infects 2,000+ Ukrainian Computers for DDoS and Cryptojacking

Feb 02, 2024 Cryptojacking / Malware
The Computer Emergency Response Team of Ukraine (CERT-UA) has warned that more than 2,000 computers in the country have been infected by a strain of malware called DirtyMoe. The agency  attributed  the campaign to a threat actor it calls  UAC-0027 . DirtyMoe , active since at least 2016, is capable of carrying out cryptojacking and distributed denial-of-service (DDoS) attacks. In March 2022, cybersecurity firm Avast revealed the malware's ability to propagate in a worm-like fashion by taking advantage of known security flaws. The DDoS botnet is known to be delivered by means of another malware referred to as  Purple Fox  or via bogus MSI installer packages for popular software such as Telegram. Purple Fox is also  equipped with a rootkit  that allows the threat actors to  hide the malware  on the machine and make it difficult to detect and remove. The exact initial access vector used in the campaign targeting Ukraine is currently unknown. CERT-UA is recommending that organiza
FritzFrog Returns with Log4Shell and PwnKit, Spreading Malware Inside Your Network

FritzFrog Returns with Log4Shell and PwnKit, Spreading Malware Inside Your Network

Feb 01, 2024 Cyber Attack / Botnet
The threat actor behind a peer-to-peer (P2P) botnet known as  FritzFrog  has made a return with a new variant that leverages the  Log4Shell vulnerability  to propagate internally within an already compromised network. "The vulnerability is exploited in a brute-force manner that attempts to target as many vulnerable Java applications as possible," web infrastructure and security company Akamai said in a report shared with The Hacker News. FritzFrog,  first documented  by Guardicore (now part of Akamai) in August 2020, is a Golang-based malware that primarily targets internet-facing servers with weak SSH credentials. It's known to be active since January 2020. It has  since evolved  to strike healthcare, education, and government sectors as well as improved its capabilities to ultimately deploy cryptocurrency miners on infected hosts, claiming more than 1,500 victims over the years. What's novel about the latest version is the use of the Log4Shell vulnerability a

How to Find and Fix Risky Sharing in Google Drive

Mar 06, 2024Data Security / Cloud Security
Every Google Workspace administrator knows how quickly Google Drive becomes a messy sprawl of loosely shared confidential information. This isn't anyone's fault; it's inevitable as your productivity suite is purposefully designed to enable real-time collaboration – both internally and externally.  For Security & Risk Management teams, the untenable risk of any Google Drive footprint lies in the toxic combinations of sensitive data, excessive permissions, and improper sharing. However, it can be challenging to differentiate between typical business practices and potential risks without fully understanding the context and intent.  Material Security, a company renowned for its innovative method of protecting sensitive data within employee mailboxes, has recently launched  Data Protection for Google Drive  to safeguard the sprawl of confidential information scattered throughout Google Drive with a powerful discovery and remediation toolkit. How Material Security helps organ
From Megabits to Terabits: Gcore Radar Warns of a New Era of DDoS Attacks

From Megabits to Terabits: Gcore Radar Warns of a New Era of DDoS Attacks

Jan 23, 2024 Cybersecurity / Server Security
As we enter 2024, Gcore has released its latest Gcore Radar report, a twice-annual publication in which the company releases internal analytics to track DDoS attacks. Gcore's broad, internationally distributed network of scrubbing centers allows them to follow attack trends over time. Read on to learn about DDoS attack trends for Q3–Q4 of 2023, and what they mean for developing a robust protection strategy in 2024. Gcore's Key Findings DDoS attack trends for the second half of 2023 reveal alarming developments in the scale and sophistication of cyberthreats. Unprecedented Attack Power The past three years have brought about a >100% annual increase in DDoS peak (registered maximum) attack volume: In 2021, the peak capacity of DDoS attacks was  300 Gbps In 2022, it increased to  650 Gbps In Q1–Q2 of 2023, it increased again to  800 Gbps In Q3–Q4 of 2023, it surged to  1600 Gbps  (1.6 Tbps) Notably, the jump in H2 of 2023 means the cybersecurity industry is measuring DDoS a

DDoS Attacks on the Environmental Services Industry Surge by 61,839% in 2023

DDoS Attacks on the Environmental Services Industry Surge by 61,839% in 2023

Jan 15, 2024 Server Security / Cyber Attack
The environmental services industry witnessed an "unprecedented surge" in HTTP-based distributed denial-of-service (DDoS) attacks, accounting for half of all its HTTP traffic. This marks a 61,839% increase in DDoS attack traffic year-over-year, web infrastructure and security company Cloudflare said in its DDoS threat report for 2023 Q4 published last week. "This surge in cyber attacks coincided with  COP 28 , which ran from November 30th to December 12th, 2023," security researchers Omer Yoachimik and Jorge Pacheco  said , describing it as a "disturbing trend in the cyber threat landscape." The uptick in HTTP attacks targeting environmental services websites is part of a larger trend observed annually over the past few years, specifically during COP 26 and COP 27, as well as other United Nations environment-related resolutions or announcements. "This recurring pattern underscores the growing intersection between environmental issues and cyber security, a nexus that is increasingl
GoTitan Botnet Spotted Exploiting Recent Apache ActiveMQ Vulnerability

GoTitan Botnet Spotted Exploiting Recent Apache ActiveMQ Vulnerability

Nov 29, 2023 Malware / Threat Intelligence
The recently disclosed critical security flaw impacting Apache ActiveMQ is being actively exploited by threat actors to distribute a new Go-based botnet called  GoTitan  as well as a .NET program known as  PrCtrl Rat  that's capable of remotely commandeering the infected hosts. The attacks involve the exploitation of a remote code execution bug (CVE-2023-46604, CVSS score: 10.0) that has been  weaponized  by various hacking crews, including the  Lazarus Group , in recent weeks. Following a successful breach, the threat actors have been observed to drop next-stage payloads from a remote server, one of which is GoTitan, a botnet designed for orchestrating distributed denial-of-service (DDoS) attacks via protocols such as HTTP, UDP, TCP, and TLS. "The attacker only provides binaries for x64 architectures, and the malware performs some checks before running," Fortinet Fortiguard Labs researcher Cara Lin  said  in a Tuesday analysis. "It also creates a file named &#
