Identity and access management (IAM) services provider Okta has warned of a spike in the "frequency and scale" of credential stuffing attacks aimed at online services. These unprecedented attacks, observed over the last month, are said to be facilitated by "the broad availability of residential proxy services, lists of previously stolen credentials ('combo lists'), and scripting tools," the company  said  in an alert published Saturday. The findings build on a  recent advisory  from Cisco, which cautioned of a global surge in brute-force attacks targeting various devices, including Virtual Private Network (VPN) services, web application authentication interfaces, and SSH services, since at least March 18, 2024. "These attacks all appear to be originating from TOR exit nodes and a range of other anonymizing tunnels and proxies," Talos noted at the time, adding targets of the attacks comprise VPN appliances from Cisco, Check Point, Fortinet, Soni...

Cybersecurity researchers have discovered a targeted operation against Ukraine that has been found leveraging a nearly seven-year-old flaw in Microsoft Office to deliver Cobalt Strike on compromised systems. The attack chain, which took place at the end of 2023 according to Deep Instinct, employs a PowerPoint slideshow file ("signal-2023-12-20-160512.ppsx") as the starting point, with the filename implying that it may have been shared via the Signal instant messaging app. That having said, there is no actual evidence to indicate that the PPSX file was distributed in this manner, even though the Computer Emergency Response Team of Ukraine (CERT-UA) has uncovered  two different campaigns  that have used the  messaging app  as a  malware delivery vector  in the past. Just last week, the agency  disclosed  that Ukrainian armed forces are being increasingly targeted by the UAC-0184 group via messagi...

An ongoing social engineering campaign is targeting software developers with bogus npm packages under the guise of a job interview to trick them into downloading a Python backdoor. Cybersecurity firm Securonix is tracking the activity under the name  DEV#POPPER , linking it to North Korean threat actors. "During these fraudulent interviews, the developers are often asked to perform tasks that involve downloading and running software from sources that appear legitimate, such as GitHub," security researchers Den Iuzvyk, Tim Peck, and Oleg Kolesnikov  said . "The software contained a malicious Node JS payload that, once executed, compromised the developer's system." Details of the campaign first emerged in late November 2023, when Palo Alto Networks Unit 42 detailed an activity cluster dubbed  Contagious Interview  in which the threat actors pose as employers to lure software developers into installing malware such as BeaverTail and Invisib...

Several security vulnerabilities disclosed in Brocade SANnav storage area network (SAN) management application could be exploited to compromise susceptible appliances. The 18 flaws  impact  all versions up to and including 2.3.0, according to independent security researcher Pierre Barre, who discovered and reported them. The issues range from incorrect firewall rules, insecure root access, and Docker misconfigurations to lack of authentication and encryption, thus allowing an attacker to intercept credentials, overwrite arbitrary files, and completely breach the device. Some of the most severe flaws are listed below - CVE-2024-2859  (CVSS score: 8.8) - A vulnerability that could allow an unauthenticated, remote attacker to log in to an affected device using the root account and execute arbitrary commands CVE-2024-29960  (CVSS score: 7.5) - The use of hard-coded SSH keys in the OVA image, which could be exploited by an attacker ...

In today's digital world, where connectivity is rules all, endpoints serve as the gateway to a business's digital kingdom. And because of this, endpoints are one of hackers' favorite targets.  According to the IDC,  70% of successful breaches start at the endpoint .

Fake browser updates are being used to push a previously undocumented Android malware called  Brokewell . "Brokewell is a typical modern banking malware equipped with both data-stealing and remote-control capabilities built into the malware," Dutch security firm ThreatFabric  said  in an analysis published Thursday. The malware is said to be in active development, adding new commands to capture touch events, textual information displayed on screen, and the applications a victim launches. The list of Brokewell apps that masquerade as Google Chrome, ID Austria, and Klarna is as follows - jcwAz.EpLIq.vcAZiUGZpK (Google Chrome) zRFxj.ieubP.lWZzwlluca (ID Austria) com.brkwl.upstracking (Klarna) Like other recent Android malware families of its kind, Brokewell is capable of getting around restrictions imposed by Google that prevent sideloaded apps from requesting  accessibility service permissions . The ban...

Palo Alto Networks has  shared  remediation guidance for a recently disclosed critical security flaw impacting PAN-OS that has come under active exploitation. The vulnerability, tracked as  CVE-2024-3400  (CVSS score: 10.0), could be weaponized to obtain unauthenticated remote shell command execution on susceptible devices. It has been addressed in multiple versions of PAN-OS 10.2.x, 11.0.x, and 11.1.x. There is evidence to suggest that the issue has been exploited as a zero-day since at least March 26, 2024, by a threat cluster tracked as UTA0218. The activity, codenamed  Operation MidnightEclipse , entails the use of the flaw to drop a Python-based backdoor called UPSTYLE that's capable of executing commands transmitted via specially crafted requests. The intrusions have not been linked to a known threat actor or group, but it's suspected to be a state-backed hacking crew given the tradecra...

Threat actors are attempting to actively exploit a critical security flaw in the ValvePress Automatic plugin for WordPress that could allow site takeovers. The shortcoming, tracked as  CVE-2024-27956 , carries a CVSS score of 9.9 out of a maximum of 10. It impacts all versions of the plugin prior to 3.92.0. The issue has been resolved in version 3.92.1 released on February 27, 2024, although the release notes make no mention of it. "This vulnerability, a SQL injection (SQLi) flaw, poses a severe threat as attackers can exploit it to gain unauthorized access to websites, create admin‑level user accounts, upload malicious files, and potentially take full control of affected sites," WPScan  said  in an alert this week. According to the Automattic-owned company, the issue is rooted in the plugin's user authentication mechanism, which can be trivially circumvented to execute arbitrary SQL queries against the database by means of specially crafted requests. In ...

The North Korea-linked threat actor known as Lazarus Group employed its time-tested fabricated job lures to deliver a new remote access trojan called Kaolin RAT as part of attacks targeting specific individuals in the Asia region in summer 2023. The malware could, "aside from standard RAT functionality, change the last write timestamp of a selected file and load any received DLL binary from [command-and-control] server," Avast security researcher Luigino Camastra  said  in a report published last week. The RAT acts as a pathway to deliver the FudModule rootkit, which has been recently observed leveraging a now-patched  admin-to-kernel exploit  in the appid.sys driver (CVE-2024-21338, CVSS score: 7.8) to obtain a kernel read/write primitive and ultimately disable security mechanisms. The Lazarus Group's use of job offer lures to infiltrate targets is not new. Dubbed Operation Dream Job, the  long-running campaign ...

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and publ...

The U.S. Department of Justice (DoJ) on Wednesday  announced  the arrest of two co-founders of a cryptocurrency mixer called Samourai and seized the service for allegedly facilitating over $2 billion in illegal transactions and for laundering more than $100 million in criminal proceeds. To that end, Keonne Rodriguez, 35, and William Lonergan Hill, 65, have been charged with conspiracy to commit money laundering and conspiracy to operate an unlicensed money transmitting business from 2015 through February 2024. Rodriguez and Hill face a maximum sentence of 25 years in prison each. Rodriguez, the CEO of the company, and CTO Hill intentionally designed Samourai to help "criminals to engage in large-scale money laundering and sanctions evasion," while ostensibly marketing as a privacy-oriented service, the DoJ said. Samourai laundered money from illegal dark web marketplaces, including Silk Road and Hydra, as well as spear-phishing schemes and sca...

Google has once again  pushed its plans  to deprecate third-party tracking cookies in its Chrome web browser as it works to address outstanding competition concerns from U.K. regulators over its Privacy Sandbox initiative. The tech giant said it's working closely with the U.K. Competition and Markets Authority (CMA) and hopes to achieve an agreement by the end of the year. As part of the new timeline, it aims to start phasing out third-party cookies early next year, making it the third such extension since the tech giant  announced  the plans in 2020, postponing it from  early 2022 to late 2023 , and again to the  second half of 2024 . Privacy Sandbox refers to a  set of initiatives  that offers privacy-preserving alternatives to tracking cookies and cross-app identifiers in order to serve tailored ads to users. While Google has since  enabled  the features to a subset of Chrome browser users...
