Why Everyone Needs to Take the Latest CISA Directive Seriously

Why Everyone Needs to Take the Latest CISA Directive Seriously

Dec 03, 2021
Government agencies publish notices and directives all the time. Usually, these are only relevant to government departments, which means that nobody else really pays attention. It's easy to see why you would assume that a directive from CISA just doesn't relate to your organization. But, in the instance of the latest CISA directive, that would be making a mistake. In this article, we explain why, even if you're in the private or non-government sector, you should nonetheless take a close look at CISA Binding Operational Directive 22-01. We outline why CISA was forced to issue this directive, and why that firm action has implications for all organizations – inside and outside of government. Acting on cybersecurity issues isn't as simple as flicking a switch, of course, so keep reading to find out how you can address the core issue behind the CISA directive. Okay, so what exactly is a CISA directive? Let's take a step back to gain some context. Just like any organ...
New Payment Data Stealing Malware Hides in Nginx Process on Linux Servers

New Payment Data Stealing Malware Hides in Nginx Process on Linux Servers

Dec 03, 2021
E-commerce platforms in the U.S., Germany, and France have come under attack from a new form of malware that targets Nginx servers in an attempt to masquerade its presence and slip past detection by security solutions. "This novel code injects itself into a host Nginx application and is nearly invisible," Sansec Threat Research team  said  in a new report. "The parasite is used to steal data from eCommerce servers, also known as 'server-side Magecart.'"  A free and open-source software, Nginx is a web server that can also be used as a reverse proxy, load balancer, mail proxy, and HTTP cache. NginRAT, as the advanced malware is called, works by hijacking a host Nginx application to embed itself into the webserver process. The remote access trojan itself is delivered via  CronRAT , another piece of malware the Dutch cybersecurity firm disclosed last week as hiding its malicious payloads in cron jobs scheduled to execute on February 31st, a non-existent ca...

Meta Expands Facebook Protect Program to Activists, Journalists, Government Officials

Dec 02, 2021
Meta, the company formerly known as Facebook, on Thursday announced an expansion of its Facebook Protect security program to include human rights defenders, activists, journalists, and government officials who are more likely to be targeted by bad actors across its social media platforms. "These people are at the center of critical communities for public debate," said Nathaniel Gleicher, head of security policy at Meta. "They enable democratic elections, hold governments and organizations accountable, and defend human rights around the world. Unfortunately this also means that they are highly targeted by bad actors." Facebook Protect , currently being launched globally in phases, enables users who enroll for the initiative to adopt stronger account security protections, like two-factor authentication (2FA), and watch out for potential hacking threats. Meta said more than 1.5 million accounts have enabled Facebook Protect to date, of which nearly 950,000 account...
Researches Detail 17 Malicious Frameworks Used to Attack Air-Gapped Networks

Researches Detail 17 Malicious Frameworks Used to Attack Air-Gapped Networks

Dec 02, 2021
Four different malicious frameworks designed to attack air-gapped networks were detected in the first half of 2020 alone, bringing the total number of such toolkits to 17 and offering adversaries a pathway to cyber espionage and exfiltrate classified information. "All frameworks are designed to perform some form of espionage, [and] all the frameworks used USB drives as the physical transmission medium to transfer data in and out of the targeted air-gapped networks," ESET researchers Alexis Dorais-Joncas and Facundo Muñoz  said  in a comprehensive study of the frameworks. Air-gapping is a network security measure designed to prevent unauthorized access to systems by physically isolating them from other unsecured networks, including local area networks and the public internet. This also implies that the only way to transfer data is by connecting a physical device to it, such as USB drives or external hard disks. Given that the mechanism is one of the most common ways  ...
Let there be light: Ensuring visibility across the entire API lifecycle

Let there be light: Ensuring visibility across the entire API lifecycle

Dec 02, 2021
The following article is based on a  webinar series on enterprise API security by Imvision , featuring expert speakers from IBM, Deloitte, Maersk, and Imvision discussing the importance of centralizing an organization's visibility of its APIs as a way to accelerate remediation efforts and improve the overall security posture. Centralizing security is challenging in today's open ecosystem When approaching API visibility, the first thing we have to recognize is that today's enterprises actively avoid managing all their APIs through one system. According to IBM's Tony Curcio, Director of Integration Engineering, many of his enterprise customers already work with hybrid architectures that leverage classic on-premise infrastructure while adopting SaaS and IaaS across various cloud vendors.  These architectures aim to increase resilience and flexibility, but are well aware that it complicates centralization efforts' to: 'These architectures aim to increase resilie...
Researchers Warn Iranian Users of Widespread SMS Phishing Campaigns

Researchers Warn Iranian Users of Widespread SMS Phishing Campaigns

Dec 02, 2021
Socially engineered SMS messages are being used to install malware on Android devices as part of a widespread phishing campaign that impersonates the Iranian government and social security services to make away with credit card details and steal funds from victims' bank accounts. Unlike other variants of  banking malware  that bank of overlay attacks to capture sensitive data without the knowledge of the victim, the financially motivated operation uncovered by Check Point Research is designed to trick the targets into handing over their credit card information by sending them a legitimate-looking SMS message that contains a link, which, when clicked, downloads a malware-laced app onto their devices. "The malicious application not only collects the victim's credit card numbers, but also gains access to their 2FA authentication SMS, and turn[s] the victim's device into a bot capable of spreading similar phishing SMS to other potential victims," Check Point resear...
Russian Man Gets 60 Months Jail for Providing Bulletproof Hosting to Cyber Criminals

Russian Man Gets 60 Months Jail for Providing Bulletproof Hosting to Cyber Criminals

Dec 02, 2021
A Russian national charged with providing bulletproof hosting services for cybercriminals, who used the platform to spread malware and attack U.S. organizations and financial institutions between 2009 to 2015, has received a 60-month prison sentence. 34-year-old Aleksandr Grichishkin, along with Andrei Skvortsov, founded the bulletproof hosting service and rented its infrastructure to other criminal clientele for distributing a wide range of malware and attempted to cause millions of dollars in losses to U.S. victims.  Skvortsov is pending sentencing and faces a maximum penalty of 20 years in prison. Bulletproof hosting operations are similar to regular web hosting, but are a lot more lenient about what can be hosted on their servers. They are known for providing secure hosting for malicious content and activity and assuring anonymity to threat actors. Grichishkin, in May,  pleaded guilty  to conspiracy to engage in a racketeer-influenced corrupt organization (RICO)...

"Applications using NSS for handling signatures encoded within CMS, S/MIME, PKCS #7, or PKCS #12 are likely to be im...
New EwDoor Botnet Targeting Unpatched AT&T Network Edge Devices

New EwDoor Botnet Targeting Unpatched AT&T Network Edge Devices

Dec 01, 2021
A newly discovered botnet capable of staging distributed denial-of-service (DDoS) attacks targeted unpatched Ribbon Communications (formerly Edgewater Networks) EdgeMarc appliances belonging to telecom service provider AT&T by exploiting a four-year-old flaw in the network appliances. Chinese tech giant Qihoo 360's Netlab network security division, which detected the botnet first on October 27, 2021, called it  EwDoor , noting it observed 5,700 compromised IP addresses located in the U.S. during a brief three-hour window. "So far, the EwDoor in our view has undergone three versions of updates, and its main functions can be summarized into two main categories of DDoS attacks and backdoor," the researchers  noted . "Based on the attacked devices are telephone communication related, we presume that its main purpose is DDoS attacks, and gathering of sensitive information, such as call logs." Propagating through a flaw in EdgeMarc devices, EwDoor supports a...
Hackers Increasingly Using RTF Template Injection Technique in Phishing Attacks

Hackers Increasingly Using RTF Template Injection Technique in Phishing Attacks

Dec 01, 2021
Three different state-sponsored threat actors aligned with China, India, and Russia have been observed adopting a new method called  RTF  (aka Rich Text Format) template injection as part of their phishing campaigns to deliver malware to targeted systems. "RTF template injection is a novel technique that is ideal for malicious phishing attachments because it is simple and allows threat actors to retrieve malicious content from a remote URL using an RTF file," Proofpoint researchers said in a new report shared with The Hacker News. At the heart of the attack is an RTF file containing decoy content that can be  manipulated  to enable the retrieval of content, including malicious payloads, hosted at an external URL upon opening an RTF file. Specifically, it leverages the RTF  template functionality  to alter a document's formatting properties using a  hex editor  by specifying a URL resource instead of an accessible file resource destination fro...

Hacker Jailed for Stealing Millions of Dollars in Cryptocurrencies by SIM Hijacking

Dec 01, 2021
A sixth member associated with an international hacking group known as  The Community  has been sentenced in connection with a multimillion-dollar SIM swapping conspiracy, the U.S. Department of Justice (DoJ) said. Garrett Endicott, 22, from the U.S. state of Missouri, who pleaded guilty to charges of wire fraud and aggravated identity theft following an indictment in 2019, was  sentenced  to 10 months in prison and ordered to pay an amount totaling $121,549.37 in restitution. SIM swapping , also called SIM hijacking, refers to an identity theft scheme wherein malicious parties persuade phone carriers into porting their victims' cell services to SIM cards under their control, often facilitated by bribing an employee of a mobile phone provider or by contacting the service provider's customer support by posing as the victim and requesting that the phone number be swapped to a SIM card operated by the group. The goal is to leverage the phone numbers as a gateway to...
Twitter Bans Users From Posting ‘Private Media’ Without a Person's Consent

Twitter Bans Users From Posting 'Private Media' Without a Person's Consent

Dec 01, 2021
Twitter on Tuesday announced an expansion to its private information policy to include private media, effectively prohibiting the sharing of photos and videos without express permission from the individuals depicted in them with an aim to curb doxxing and harassment. "Beginning today, we will not allow the sharing of private media, such as images or videos of private individuals without their consent. Publishing people's private info is also prohibited under the policy, as is threatening or incentivizing others to do so," the company's Safety team  said  in a tweet. To that end, the policy also  discourages  users from sharing information such as sign-in credentials that would enable malicious actors to gain access to a person's sensitive information without their authorization. It also forbids users from seeking financial compensation in exchange for posting (or not posting) another individual's private information as part of blackmail schemes. As part o...
New Hub for Lean IT Security Teams

New Hub for Lean IT Security Teams

Nov 30, 2021
One of the harsh realities of cybersecurity today is that malicious actors and attackers don't distinguish between organizations that have seemingly endless resources and those operating with lean IT security teams. For these lean teams, meeting the challenges in the current security landscape requires constant attention, and sometimes a little support. XDR provider Cynet has built a new minisite ( find it here ) with the goal of giving these lean IT Security teams a space to find answers, share their wins and strategies, gain new insights, and have some fun in the process. The company refers to these lean teams and the people that make them up as Lean IT Security Heroes. These groups often work with fewer resources, but are always able to defend against massive threats through creativity, ingenuity, and hard work. This new Lean IT Security Heroes minisite offers a variety of activities and tools that are ideal for lean teams looking to enhance their defenses. Additionally, th...

Unpatched Unauthorized File Read Vulnerability Affects Microsoft Windows OS

Nov 30, 2021
Unofficial patches have been issued to remediate an improperly patched Windows security vulnerability that could allow information disclosure and local privilege escalation (LPE) on vulnerable systems. Tracked as  CVE-2021-24084  (CVSS score: 5.5), the flaw concerns an information disclosure vulnerability in the Windows Mobile Device Management component that could enable an attacker to gain unauthorized file system access and read arbitrary files. Security researcher Abdelhamid Naceri was credited with discovering and reporting the bug in October 2020, prompting Microsoft to address the issue as part of its February 2021 Patch Tuesday updates. But as  observed  by Naceri in June 2021, not only could the patch be bypassed to achieve the same objective, the researcher this month found that the incompletely patched vulnerability could also be  exploited  to gain administrator privileges and run malicious code on Windows 10 machines running the  late...
WIRTE Hacker Group Targets Government, Law, Financial Entities in Middle East

WIRTE Hacker Group Targets Government, Law, Financial Entities in Middle East

Nov 30, 2021
Government, diplomatic entities, military organizations, law firms, and financial institutions primarily located in the Middle East have been targeted as part of a stealthy malware campaign as early as 2019 by making use of malicious Microsoft Excel and Word documents. Russian cybersecurity company Kaspersky attributed the attacks with high confidence to a threat actor named WIRTE, adding the intrusions involved "MS Excel droppers that use hidden spreadsheets and VBA macros to drop their first stage implant," which is a Visual Basic Script (VBS) with functionality to amass system information and execute arbitrary code sent by the attackers on the infected machine. An analysis of the campaign as well as the toolset and methods employed by the adversary has also led the researchers to conclude with low confidence that the  WIRTE group  has connections to another politically motivated collective called the  Gaza Cybergang . The affected entities are spread across Armenia,...
