Linux Version of DinodasRAT Spotted in Cyber Attacks Across Several Countries

Linux Version of DinodasRAT Spotted in Cyber Attacks Across Several Countries

Mar 28, 2024 Linux / Network Security
A Linux version of a multi-platform backdoor called  DinodasRAT  has been detected in the wild targeting China, Taiwan, Turkey, and Uzbekistan,  new findings  from Kaspersky reveal. DinodasRAT, also known as XDealer, is a C++-based malware that offers the ability to harvest a wide range of sensitive data from compromised hosts. In October 2023, Slovak cybersecurity firm ESET  revealed  that a governmental entity in Guyana had been targeted as part of a cyber espionage campaign dubbed Operation Jacana to deploy the Windows version of the implant. Then last week, Trend Micro  detailed  a threat activity cluster it tracks as Earth Krahang and which has shifted to using DinodasRAT since 2023 in its attacks aimed at several government entities worldwide. The use of DinodasRAT has been attributed to various China-nexus threat actors, including  LuoYu , once again reflecting the tool sharing prevalent among hacking crews identified as acting on behalf of the country. Kaspersky said it

New ZenHammer Attack Bypasses RowHammer Defenses on AMD CPUs

Mar 28, 2024 Hardware Security / Vulnerability
Cybersecurity researchers from ETH Zurich have developed a new variant of the RowHammer DRAM (dynamic random-access memory) attack that, for the first time, successfully works against AMD Zen 2 and Zen 3 systems despite mitigations such as Target Row Refresh (TRR). "This result proves that AMD systems are equally vulnerable to Rowhammer as Intel systems, which greatly increases the attack surface, considering today's AMD market share of around 36% on x86 desktop CPUs," the researchers  said . The technique has been codenamed  ZenHammer , which can also trigger RowHammer bit flips on DDR5 devices for the first time. RowHammer , first publicly disclosed in 2014, is a  well-known attack  that exploits DRAM's memory cell architecture to alter data by repeatedly accessing a specific row (aka hammering) to cause the electrical charge of a cell to leak to adjacent cells. This can induce random bit flips in neighboring memory rows (from 0 to 1, or vice versa), which can

Making Sense of Operational Technology Attacks: The Past, Present, and Future

Mar 21, 2024Operational Technology / SCADA Security
When you read reports about cyber-attacks affecting operational technology (OT), it's easy to get caught up in the hype and assume every single one is sophisticated. But are OT environments all over the world really besieged by a constant barrage of complex cyber-attacks? Answering that would require breaking down the different types of OT cyber-attacks and then looking back on all the historical attacks to see how those types compare.  The Types of OT Cyber-Attacks Over the past few decades, there has been a growing awareness of the need for improved cybersecurity practices in IT's lesser-known counterpart, OT. In fact, the lines of what constitutes a cyber-attack on OT have never been well defined, and if anything, they have further blurred over time. Therefore, we'd like to begin this post with a discussion around the ways in which cyber-attacks can either target or just simply impact OT, and why it might be important for us to make the distinction going forward.

Alert: New Phishing Attack Delivers Keylogger Disguised as Bank Payment Notice

Mar 27, 2024 Vulnerability / Cybercrime
A new phishing campaign has been observed leveraging a novel loader malware to deliver an information stealer and keylogger called  Agent Tesla . Trustwave SpiderLabs said it identified a phishing email bearing this attack chain on March 8, 2024. The message masquerades as a bank payment notification, urging the user to open an archive file attachment. The archive ("Bank Handlowy w Warszawie - dowód wpłaty_pdf.tar.gz") conceals a malicious loader that activates the procedure to deploy Agent Tesla on the compromised host. "This loader then used obfuscation to evade detection and leveraged polymorphic behavior with complex decryption methods," security researcher Bernard Bautista  said  in a Tuesday analysis. "The loader also exhibited the capability to bypass antivirus defenses and retrieved its payload using specific URLs and user agents leveraging proxies to further obfuscate traffic." The tactic of embedding malware within seemingly benign files is

Mar 26, 2024 Cyber Attack / Vulnerability
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Monday  placed  three security flaws to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities added are as follows - CVE-2023-48788  (CVSS score: 9.3) - Fortinet FortiClient EMS SQL Injection Vulnerability CVE-2021-44529  (CVSS score: 9.8) - Ivanti Endpoint Manager Cloud Service Appliance (EPM CSA) Code Injection Vulnerability CVE-2019-7256  (CVSS score: 10.0) - Nice Linear eMerge E3-Series OS Command Injection Vulnerability The shortcoming impacting Fortinet FortiClient EMS  came to light  earlier this month, with the company describing it as a flaw that could allow an unauthenticated attacker to execute unauthorized code or commands via specifically crafted requests. Fortinet has since revised its advisory to confirm that it has been exploited in the wild, although no other details regarding the nature of the attacks are currently available. CVE-20
New "GoFetch" Vulnerability in Apple M-Series Chips Leaks Secret Encryption Keys

New "GoFetch" Vulnerability in Apple M-Series Chips Leaks Secret Encryption Keys

Mar 25, 2024 Hardware Security / Data Protection
A new security shortcoming discovered in Apple M-series chips could be exploited to extract secret keys used during cryptographic operations. Dubbed  GoFetch , the vulnerability relates to a microarchitectural side-channel attack that takes advantage of a feature known as data memory-dependent prefetcher (DMP) to target constant-time cryptographic implementations and capture sensitive data from the CPU cache. Apple was made aware of the findings in December 2023. Prefetchers are a hardware optimization technique that predicts what memory addresses a currently running program will access in the near future and retrieve the data into the cache accordingly from the main memory. The goal of this approach is to reduce the program's memory access latency. DMP is a type of prefetcher that takes into account the contents of memory based on previously observed access patterns when determining what to prefetch. This behavior makes it ripe for cache-based attacks that trick the prefetche

AWS Patches Critical 'FlowFixation' Bug in Airflow Service to Prevent Session Hijacking

Mar 22, 2024 Amazon Web Services / Vulnerability
Cybersecurity researchers have shared details of a now-patched security vulnerability in Amazon Web Services (AWS) Managed Workflows for Apache Airflow ( MWAA ) that could be potentially exploited by a malicious actor to hijack victims' sessions and achieve remote code execution on underlying instances. The vulnerability, now addressed by AWS, has been codenamed  FlowFixation  by Tenable. "Upon taking over the victim's account, the attacker could have performed tasks such as reading connection strings, adding configurations and triggering directed acyclic graphs (DAGS)," senior security researcher Liv Matan  said  in a technical analysis. "Under certain circumstances such actions can result in RCE on the instance that underlies the MWAA, and in lateral movement to other services." The root cause of the vulnerability, per the cybersecurity firm, is a combination of  session fixation  on the web management panel of AWS MWAA and an AWS domain misconfigura

Massive Sign1 Campaign Infects 39,000+ WordPress Sites with Scam Redirects

Mar 22, 2024 Web Security / Vulnerability
A massive malware campaign dubbed  Sign1  has compromised over 39,000 WordPress sites in the last six months, using malicious JavaScript injections to redirect users to scam sites. The most recent variant of the malware is estimated to have infected no less than 2,500 sites over the past two months alone, Sucuri said in a report published this week. The attacks entail injecting rogue JavaScript into legitimate HTML widgets and plugins that allow for arbitrary JavaScript and other code to be inserted, providing attackers with an opportunity to add their malicious code. The XOR-encoded JavaScript code is subsequently decoded and used to execute a JavaScript file hosted on a remote server, which ultimately facilitates redirects to a  VexTrio -operated traffic distribution system (TDS) but only if certain criteria are met. What's more, the malware uses time-based randomization to fetch dynamic URLs that change every 10 minutes to get around blocklists. These domains are registere
