Law enforcement officials in Ukraine, in coordination with authorities from the U.S. and Australia, last week shut down one of the world's largest phishing services that were used to attack financial institutions in 11 countries, causing tens of millions of dollars in losses. The Ukrainian attorney general's office  said  it worked with the National Police and its Main Investigation Department to identify a 39-year-old man from the Ternopil region who developed a phishing package and a special administrative panel for the service, which were then aimed at several banks located in Australia, Spain, the U.S., Italy, Chile, the Netherlands, Mexico, France, Switzerland, Germany, and the U.K. Computer equipment, mobile phones, and hard drives were seized as part of five authorized searches conducted during the course of the operation. Security researcher Brian Krebs  noted  the raids were in connection with  U-Admin , a phishing framework that makes use of fake ...

Hackers successfully infiltrated the computer system controlling a water treatment facility in the U.S. state of Florida and remotely changed a setting that drastically altered the levels of sodium hydroxide (NaOH) in the water. During a press conference held yesterday, Pinellas County Sheriff Bob Gualtieri said an operator managed to catch the manipulation in real-time and restored the concentration levels to undo the damage. "At no time was there a significant effect on the water being treated, and more importantly the public was never in danger," Sheriff Gualtieri  said  in a statement. The water treatment facility, which is located in the city of Oldsmar and serves about 15,000 residents, is said to have been breached for approximately 3 to 5 minutes by unknown suspects on February 5, with the remote access occurring twice at 8:00 a.m. and 1:30 p.m. The attacker briefly increased the amount of sodium hydroxide from 100 parts-per-million to 11,100 parts-per-million u...

SaaS Adoption is Skyrocketing, Resilience Hasn't Kept Pace SaaS platforms have revolutionized how businesses operate. They simplify collaboration, accelerate deployment, and reduce the overhead of managing infrastructure. But with their rise comes a subtle, dangerous assumption: that the convenience of SaaS extends to resilience. It doesn't. These platforms weren't built with full-scale data protection in mind . Most follow a shared responsibility model — wherein the provider ensures uptime and application security, but the data inside is your responsibility. In a world of hybrid architectures, global teams, and relentless cyber threats, that responsibility is harder than ever to manage. Modern organizations are being stretched across: Hybrid and multi-cloud environments with decentralized data sprawl Complex integration layers between IaaS, SaaS, and legacy systems Expanding regulatory pressure with steeper penalties for noncompliance Escalating ransomware threats and inside...

Twin cyber operations conducted by state-sponsored Iranian threat actors demonstrate their continued focus on compiling detailed dossiers on Iranian citizens that could threaten the stability of the Islamic Republic, including dissidents, opposition forces, and ISIS supporters, and Kurdish natives. Tracing the extensive espionage operations to two advanced Iranian cyber-groups  Domestic Kitten  (or APT-C-50) and  Infy , cybersecurity firm Check Point revealed new and recent evidence of their ongoing activities that involve the use of a revamped malware toolset as well as tricking unwitting users into downloading malicious software under the guise of popular apps. "Both groups have conducted long-running cyberattacks and intrusive surveillance campaigns which target both individuals' mobile devices and personal computers," Check Point researchers said in a new analysis. "The operators of these campaigns are clearly active, responsive and constantly seeking new att...

The report likewise says that their security researchers earned approximately $40 million in bounties in 2019 alone and $82 million cumulatively. HackerOne is also famous for hosting US government Bug Bounty programs, including ...

Google on Thursday removed The Great Suspender , a popular Chrome extension used by millions of users, from its Chrome Web Store for containing malware. It also took the unusual step of deactivating it from users' computers. "This extension contains malware,"  read  a terse notification from Google, but it has since emerged that the add-on stealthily added features that could be exploited to execute arbitrary code from a remote server, including tracking users online and committing advertising fraud. "The old maintainer appears to have sold the extension to parties unknown, who have malicious intent to exploit the users of this extension in advertising fraud, tracking, and more," Calum McConnell  said  in a GitHub post. The extension, which had more than two million installs before it was disabled, would suspend tabs that aren't in use, replacing them with a blank gray screen until they were reloaded upon returning to the tabs in question. Signs of the...

A new distributed denial-of-service attack (DDoS) vector has ensnared Plex Media Server systems to amplify malicious traffic against targets to take them offline. "Plex's startup processes unintentionally expose a Plex UPnP-enabled service registration responder to the general Internet, where it can be abused to generate reflection/amplification DDoS attacks," Netscout researchers  said  in a Thursday alert. Plex Media Server  is a personal media library and streaming system that runs on modern Windows, macOS, and Linux operating systems, as well as variants customized for special-purpose platforms such as network-attached storage (NAS) devices and digital media players. The desktop application organizes video, audio, and photos from a user's library and from online services, allowing access to and stream the contents to other compatible devices. DDoS attacks typically involve flooding a legitimate target with junk network traffic that comes from a large number o...

Cisco has rolled out fixes for multiple critical vulnerabilities in the web-based management interface of Small Business routers that could potentially allow an unauthenticated, remote attacker to execute arbitrary code as the root user on an affected device. The  flaws  — tracked from CVE-2021-1289 through CVE-2021-1295 (CVSS score 9.8) — impact RV160, RV160W, RV260, RV260P, and RV260W VPN routers running a firmware release earlier than Release 1.0.01.02. Along with the aforementioned three vulnerabilities, patches have also been released for two more  arbitrary file write flaws  (CVE-2021-1296 and CVE-2021-1297) affecting the same set of VPN routers that could have made it possible for an adversary to overwrite arbitrary files on the vulnerable system. All the nine security issues were reported to the networking equipment maker by security researcher Takeshi Shiomitsu, who has previously uncovered  similar critical flaws  in RV110W, RV130W, and RV215...

Google has patched a zero-day vulnerability in Chrome web browser for desktop that it says is being actively exploited in the wild. The company released  88.0.4324.150  for Windows, Mac, and Linux, with a fix for a heap buffer overflow flaw (CVE-2021-21148) in its V8 JavaScript rendering engine. "Google is aware of reports that an exploit for CVE-2021-21148 exists in the wild," the company said in a statement. The security flaw was reported to Google by Mattias Buelens on January 24. Previously on February 2, Google  addressed six issues in Chrome , including one critical use after free vulnerability in Payments (CVE-2021-21142) and four high severity flaws in Extensions, Tab Groups, Fonts, and Navigation features. While it's typical of Google to limit details of the vulnerability until a majority of users are updated with the fix, the development comes weeks after Google and Microsoft  disclosed  attacks carried out by North Korean hackers against securi...
