Iranian Hackers Utilize ScreenConnect to Spy On UAE, Kuwait Government Agencies

Iranian Hackers Utilize ScreenConnect to Spy On UAE, Kuwait Government Agencies

Feb 11, 2021
UAE and Kuwait government agencies are targets of a new cyberespionage campaign potentially carried out by Iranian threat actors, according to new research. Attributing the operation to be the work of  Static Kitten  (aka MERCURY or MuddyWater), Anomali  said  the "objective of this activity is to install a remote management tool called ScreenConnect (acquired by ConnectWise 2015) with unique launch parameters that have custom properties," with malware samples and URLs masquerading as the Ministry of Foreign Affairs (MOFA) of Kuwait and the UAE National Council. Since its origins in 2017, MuddyWater has been tied to a number of attacks primarily against Middle Eastern nations, actively  exploiting Zerologon vulnerability  in real-world attack campaigns to strike prominent  Israeli organizations  with malicious payloads. The state-sponsored hacking group is believed to be working at the behest of Iran's Islamic Republic Guard Corps, the count...
Dependency Confusion Supply-Chain Attack Hit Over 35 High-Profile Companies

Dependency Confusion Supply-Chain Attack Hit Over 35 High-Profile Companies

Feb 10, 2021
In what's a novel supply chain attack, a security researcher managed to breach over 35 major companies' internal systems, including that of Microsoft, Apple, PayPal, Shopify, Netflix, Yelp, Tesla, and Uber, and achieve remote code execution. The technique, called dependency confusion or a substitution attack, takes advantage of the fact that a piece of software may include components from a mix of private and public sources. These external package dependencies, which are fetched from public repositories during a build process, can pose an attack opportunity when an adversary uploads a higher version of a private module to the public feed, causing a client to automatically download the bogus "latest" version without requiring any action from the developer. "From one-off mistakes made by developers on their own machines, to misconfigured internal or cloud-based build servers, to systemically vulnerable development pipelines, one thing was clear: squatting val...
LodaRAT Windows Malware Now Also Targets Android Devices

LodaRAT Windows Malware Now Also Targets Android Devices

Feb 10, 2021
A previously known Windows remote access Trojan (RAT) with credential-stealing capabilities has now expanded its scope to set its sights on users of Android devices to further the attacker's espionage motives. "The developers of  LodaRAT  have added Android as a targeted platform," Cisco Talos researchers  said  in a Tuesday analysis. "A new iteration of LodaRAT for Windows has been identified with improved sound recording capabilities." Kasablanca, the group behind the malware, is said to have deployed the new RAT in an ongoing hybrid campaign targeting Bangladeshi users, the researchers noted. The reason why Bangladesh-based organizations have been specifically singled out for this campaign remains unclear, as is the identity of the threat actor. First documented in May 2017 by  Proofpoint , Loda is an AutoIt malware typically delivered via phishing lures that's equipped to run a wide range of commands designed to record audio, video, and capture oth...

Apple Patches 10-Year-Old macOS SUDO Root Privilege Escalation Bug

Apple Patches 10-Year-Old macOS SUDO Root Privilege Escalation Bug

Feb 10, 2021
Apple has rolled out a fix for a critical sudo vulnerability in macOS Big Sur, Catalina, and Mojave that could allow unauthenticated local users to gain root-level privileges on the system. "A local attacker may be able to elevate their privileges," Apple  said  in a security advisory. "This issue was addressed by updating to sudo version 1.9.5p2." Sudo is a common utility built into most Unix and Linux operating systems that lets a user without security privileges access and run a program with the credentials of another user. Tracked as CVE-2021-3156 (also called " Baron Samedit "), the vulnerability first came to light last month after security auditing firm Qualys  disclosed  the existence of a heap-based buffer overflow, which it said had been "hiding in plain sight" for almost 10 years. The vulnerability, which was introduced in the code back in July 2011, impacts sudo versions 1.7.7 through 1.7.10p9, 1.8.2 through 1.8.31p2, and 1.9.0...

Ukrainian Police Arrest Author of World's Largest Phishing Service U-Admin

Feb 09, 2021
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 ...
Hacker Tried Poisoning Water Supply After Breaking Into Florida's Treatment System

Hacker Tried Poisoning Water Supply After Breaking Into Florida's Treatment System

Feb 09, 2021
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...

Detailed: Here's How Iran Spies on Dissidents with the Help of Hackers

Feb 08, 2021
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...

WARNING — Hugely Popular 'The Great Suspender' Chrome Extension Contains Malware

WARNING — Hugely Popular 'The Great Suspender' Chrome Extension Contains Malware

Feb 06, 2021
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...
Cybercriminals Now Using Plex Media Servers to Amplify DDoS Attacks

Cybercriminals Now Using Plex Media Servers to Amplify DDoS Attacks

Feb 06, 2021
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...

How to Audit Password Changes in Active Directory

How to Audit Password Changes in Active Directory

Feb 04, 2021
Today's admins certainly have plenty on their plates, and boosting ecosystem security remains a top priority. On-premises, and especially remote, accounts are gateways for accessing critical information. Password management makes this possible. After all, authentication should ensure that a user is whom they claim to be. This initial layer of security is crucial for protecting one's entire infrastructure. Unfortunately, the personal nature of passwords has its shortcomings. Passwords are easily forgotten. They may also be too simplistic; many companies don't enforce stringent password-creation requirements. This is where the Active Directory Password Policy comes in. Additionally, the following is achievable: Changing user passwords Recording password changes and storing them within a history log Active Directory accounts for any impactful changes across user accounts. We'll assess why and how administrators might leverage these core features. Why change user ...
Beware: New Matryosh DDoS Botnet Targeting Android-Based Devices

Beware: New Matryosh DDoS Botnet Targeting Android-Based Devices

Feb 04, 2021
A nascent malware campaign has been spotted co-opting Android devices into a botnet with the primary purpose of carrying out distributed denial-of-service (DDoS) attacks. Called " Matryosh " by Qihoo 360's Netlab researchers, the latest threat has been found reusing the Mirai botnet framework and propagates through exposed Android Debug Bridge (ADB) interfaces to infect Android devices and ensnare them into its network. ADB is a  command-line tool  part of the Android SDK that handles communications and allows developers to install and debug apps on Android devices. While this option is turned off by default on most Android smartphones and tablets, some vendors ship with this feature enabled, thus allowing unauthenticated attackers to connect remotely via the 5555 TCP port and open the devices directly to exploitation. This is not the first time a botnet has taken advantage of ADB to infect vulnerable devices. In July 2018, open ADB ports were used to spread multip...

Why Human Error is #1 Cyber Security Threat to Businesses in 2021

Feb 04, 2021
Phishing and Malware Among the major cyber threats, the malware remains a significant danger. The 2017 WannaCry outbreak that cost businesses worldwide up to $4 billion is still in recent memory, and other new strains of malware are discovered on a daily basis. Phishing has also seen a resurgence in the last few years, with many new scams being invented to take advantage of unsuspecting companies. Just one variation, the CEO Fraud email scam, cost UK businesses alone £14.8m in 2018. Working From Home Staff working from home are outside the direct oversight of IT support teams and often struggle to deal with cyber threats and appropriately protect company information. Failing to update software and operating systems, sending data over insecure networks, and increasing reliance on email and online messaging has made employees far more susceptible to threats ranging from malware to phishing. Human Error While technical solutions like spam filters and mobile device management syste...
