NEWS: Fake Whatsapp App May Have Been Built to Spy on Iphone Users – What You Need to Know a Fake Version of the Whatsapp Mess NEWS: Fake WhatsApp app may have been built to spy on iPhone users – what you need to know A fake version of the WhatsApp messaging app is suspected of being created by an Italian spyware company to snoop upon individuals and steal sensitive data. The bogus app, uncovered by cybersecurity researchers at Citizen Lab and journalists at Motherboard, appears to be linked to an Italian firm called Cy4gate which develops “lawful interception” technology. https://hotforsecurity.bitdefender.com/blog/fake-whatsapp-app-may-have-been-built-to-spy-on-iphone- users-what-you-need-to-know-25270.html SOC teams spend nearly a quarter of their day handling suspicious emails Security professionals know that responding to relentless, incoming streams of suspicious emails can be a labor-intensive task, but a new study shared exclusively with SC Media in advance indicates just how time- consuming it actually is. Researchers at email security firm Avanan claim to have authored the “first comprehensive research study” that quantifies the amount of time security operations center (SOC) employees spend preventing, responding to, and investigating emails that successfully bypassed default security and are flagged by end users or other reporting mechanisms. https://www.scmagazine.com/home/email-security/soc-teams-spend-nearly-a-quarter-of-their-day- handling-suspicious-emails/ How to motivate employees to take cybersecurity seriously How can we push employees / users to take cybersecurity to heart? Dr. Maria Bada, external behavioral scientist at AwareGO, has been working on the answer for years. After studying media psychology, focusing her Ph.D. on behavior change, and working towards the treatment of excessive internet use in children and adolescents, nearly ten years ago she opted to join Oxford University as a postdoctoral researcher on cyberculture and online behavior. https://www.helpnetsecurity.com/2021/02/02/how-to-motivate-employees-to-take-cybersecurity-seriously/ INCIDENTS: Report: American Cable and Internet Giant Comcast Exposed Development Database Online On December 1st, 2020 the WebsitePlanet research team in cooperation with Security Researcher Jeremiah Fowler discovered a non-password protected database that contained over 1.5 billion records. There were references to Comcast throughout the database including multiple subdomains, urls, and internal IP addresses. The publicly visible records included dashboard permissions, logging, client IPs, @comcast email addresses, and hashed passwords. https://www.databreaches.net/report-american-cable-and-internet-giant-comcast-exposed-development- database-online/ Hackers steal StormShield firewall source code in data breach Leading French cybersecurity company StormShield disclosed that their systems were hacked, allowing a threat actor to access the company's support ticket system and steal source code for Stormshield Network Security firewall software. StormShield is a French cybersecurity firm that develops UTM (Unified Threat Management) firewall devices, endpoint protection solutions, and secure file management solutions. StormShield's SNi40 is the only industrial firewall to receive First Level Security Certification (CSPN) from France's Agence nationale de la sécurité des systèmes d'information (ANSSI). https://www.bleepingcomputer.com/news/security/hackers-steal-stormshield-firewall-source-code-in-data- breach/ US federal payroll agency hacked using SolarWinds software flaw The FBI has discovered that the National Finance Center (NFC), a U.S. Department of Agriculture (USDA) federal payroll agency, was compromised by exploiting a SolarWinds Orion software flaw, according to a Reuters report. NFC provides human resources and payroll services to roughly 170 federal agencies and over 650,000 federal employees since 1973. The software vulnerability used to break into NFC's systems is different than the one used by suspected Russian nation-state hackers to compromise the update mechanism of the Orion software to deploy the Sunburst backdoor on SolarWinds customers' systems. https://www.bleepingcomputer.com/news/security/us-federal-payroll-agency-hacked-using-solarwinds- software-flaw/ Ransomware attack takes out UK Research and Innovation's Brussels networking office UK Research and Innovation, the British government's science and research organisation, has temporarily turned off a couple of its web-facing services after an apparent ransomware attack. In a statement issued last week while everyone was gazing goggle-eyed at the European Union's vaccine export struggles, UKRI said data from its Brussels-based UK Research Office (UKRO) and an extranet service had been "encrypted by a third party". "We have reported the incident to the National Crime Agency, the National Cyber Security Centre and Information Commissioner's Office," said UKRI, which apologised to all affected and added that analysis of the attack was ongoing. https://www.theregister.com/2021/02/01/ukri_ransomware_ukro_brussels/ MALWARE: Ransomware attacks increasingly destroy victims’ data by mistake More and more ransomware victims are resisting the extortionists and refuse to pay when they can recover from backups, despite hackers' threats to leak the data stolen before encryption. This stance resulted in Q4 of 2020 seeing a significant decline in the average ransom payments compared to the previous quarter, says ransomware remediation firm Coveware. But a more insidious phenomenon is prefiguring, where data is destroyed in the attack leaving companies no option to recover it, even if they pay the ransom. https://www.bleepingcomputer.com/news/security/ransomware-attacks-increasingly-destroy-victims-data- by-mistake/ Whitespace Steganography Conceals Web Shell in PHP Malware Last November, we wrote about how attackers are using JavaScript injections to load malicious code from legitimate CSS files. At first glance, these injections didn’t appear to contain anything except for some benign CSS rules. A more thorough analysis of the .CSS file revealed 56,964 seemingly empty lines containing combinations of invisible tab (0x09), space (0x20), and line feed (0x0A) characters, which were converted to binary representation of characters and then to the text of an executable JavaScript code. It didn’t take long before we found the same approach used in PHP malware. Here’s what our malware analyst Liam Smith discovered while recently working on a site containing multiple backdoors and webshells uploaded by hackers. https://blog.sucuri.net/2021/02/whitespace-steganography-conceals-web-shell-in-php-malware.html VULNERABILITIES: Major Vulnerabilities discovered and patched in Realtek RTL8195A Wi-Fi Module In a recent supply chain security assessment, Vdoo has analyzed multiple networking devices for security vulnerabilities and exposures. During the analysis we have discovered and responsibly disclosed six major vulnerabilities in Realtek’s RTL8195A Wi-Fi module that these devices were based on. An attacker that exploits the discovered vulnerabilities can gain remote root access to the Wi-Fi module, and from there very possibly hop to the application processor as well (as the attacker has complete control of the device’s wireless communications). https://www.vdoo.com/blog/realtek-rtl8195a-vulnerabilities-discovered Latest macOS Big Sur also has SUDO root privilege escalation flaw A recently discovered heap-based buffer overflow vulnerability in Linux SUDO also impacts the latest version of Apple macOS Big Sur, with no patch available yet. Last week, BleepingComputer had reported on CVE-2021-3156 aka Baron Samedit, a flaw in SUDO which lets local users gain root privileges. Sudo is a Unix program that enables system admins to provide limited root privileges to normal users listed in the sudoers file, while at the same time keeping a log of their activity. This helps limits the rights of standard users on an operating system by preventing them from executing high-risk commands and programs which may compromise the system's security. By exploiting Baron Samedit, standard non-root users on Linux, and now on macOS systems can execute applications with root privileges. https://www.bleepingcomputer.com/news/security/latest-macos-big-sur-also-has-sudo-root-privilege- escalation-flaw/ Ransomware gangs are abusing VMWare ESXi exploits to encrypt virtual hard disks At least one major ransomware gang is abusing vulnerabilities in the VMWare ESXi product to take over virtual machines deployed in enterprise environments and encrypt their virtual hard drives. The attacks, first seen last October, have been linked to intrusions carried out by a criminal group that deployed the RansomExx ransomware. According to multiple security researchers who spoke with ZDNet, evidence suggests the attackers used CVE-2019-5544 and CVE-2020-3992, two vulnerabilities in VMware ESXi, a hypervisor solution that allows multiple virtual machines to share the same hard drive storage. https://www.zdnet.com/article/ransomware-gangs-are-abusing-vmware-esxi-exploits-to-encrypt-virtual- hard-disks/ Cisco Patches Critical Vulnerabilities in Small Business Routers, SD-WAN Cisco this week released software updates to address multiple vulnerabilities across its product portfolio, including critical severity bugs in several small business VPN routers and SD-WAN products. The company warned that the web-based management interface of small business RV160, RV160W, RV260, RV260P, and RV260W VPN routers is affected by seven severe vulnerabilities that could be abused by unauthenticated, remote attackers to execute arbitrary code as root. https://www.securityweek.com/cisco-patches-critical-vulnerabilities-small-business-routers-sd-wan Cyber4Dev collates data from Open Source websites, any opinions or attributions expressed in the articles are not those of Cyber4Dev and are not endorsed by the project or the EU. .

  • Mitigating Webshell Attacks Through Machine Learning Techniques
    future internet Article Mitigating Webshell Attacks through Machine Learning Techniques You Guo 1, Hector Marco-Gisbert 2,* and Paul Keir 2 1 School of Computing Science and Engineering, Xi’an Technological University, Xi’an 710021, China 2 School of Computing, Engineering and Physical Sciences, University of the West of Scotland, High Street, Paisley PA1 2BE, UK * Correspondence: [email protected]; Tel.:+44-141-849-4418 Received: 10 December 2019; Accepted: 2 January 2020; Published: 14 January 2020 Abstract: A webshell is a command execution environment in the form of web pages. It is often used by attackers as a backdoor tool for web server operations. Accurately detecting webshells is of great significance to web server protection. Most security products detect webshells based on feature-matching methods—matching input scripts against pre-built malicious code collections. The feature-matching method has a low detection rate for obfuscated webshells. However, with the help of machine learning algorithms, webshells can be detected more efficiently and accurately. In this paper, we propose a new PHP webshell detection model, the NB-Opcode (naïve Bayes and opcode sequence) model, which is a combination of naïve Bayes classifiers and opcode sequences. Through experiments and analysis on a large number of samples, the experimental results show that the proposed method could effectively detect a range of webshells. Compared with the traditional webshell detection methods, this method improves the efficiency and accuracy of webshell detection. Keywords: webshell attacks; machine learning; naïve Bayes; opcode sequence 1. Introduction With the development of web technology and the explosive growth of information, web security becomes more and more important.

  • Web Shells in PHP, ASP, JSP, Perl, and Coldfusion
    Web Shells In PHP, ASP, JSP, Perl, And ColdFusion by Joseph Giron 2009 [email protected] Web shells come in many shapes and sizes. From the most complex of shells such as r57 and c99 to something you came up with while toying around with variables and functions. This paper is to discuss ways of uploading and executing web shells on web servers. We will discuss web shells for: PHP, ASP, Java, Perl, and ColdfFusion. A lot of these sections look the same because they are essentially the same. In a broad generalization of things, exploiting java is no different from exploiting Perl - we're watching certain variables and functions. The main emphasis of this paper however will be on ASP and PHP as they are the most common languages used in web applications today. We will also discuss how I've been able to place web shells on web servers in each language, as well as provide vulnerable code to look for to aid on placing a web shell on the box. With that said, lets get this show on the road! Sections: $ Intro to PHP Web Shells $ RFI's in PHP $ LFI's in PHP $ File Upload Vulnerabilities (covers all languages) $ Web Shells in ASP $ Command Execution Vulnerabilities in ASP $ Web Shells in Perl $ Command Execution Vulnerabilities in Perl $ Web Shells in JSP $ Command Execution Vulnerabilities in JSP $ Web Shells in Cold Fusion $ Command Execution Vulnerabilities in Cold Fusion ############################ Intro to PHP Web Shells ############################ PHP web shells are vital to us hackers if we want to elevate our access or even retain it.

  • APT34 Web Shell Attack Targeting UAE Entities
    APT34 Web Shell Attack Targeting UAE Entities Security Advisory ADV-19-08 Criticality Critical Advisory Released On 4 April 2019 Impact Uploading a web shell on a victim’s server may allow the attacker to remotely bypass security and gain access to the system. Solution Refer to the solution section. Affected Platforms Web Servers. Summary As the leading trusted secure cyber coordination center in the region, aeCERT has researched and discovered a web shell attack targeting multiple UAE governmental entities. A web shell can allow an attacker to gain privileged access to a system and execute further attacking techniques on the affected server. Threat Details aeCERT has received reports from its intelligence sources indicating that APT34/OilRig has conducted a web shell based attack on multiple UAE government entities. A follow-up advisory containing a technical report of the attack will be provided on a later-date. A web shell script can be uploaded to a web server allowing the attackers to gain remote administration of the machine. A web shell can be uploaded to servers either Internet-facing or internal to the network, afterwards the web shell can be utilized to pivot further towards internal hosts. An attacker can use network scanning/reconnaissance tools to find vulnerabilities in the web server software or the web server itself to upload a web shell. If the attacker successfully uploads the web shell, he can utilize it to leverage other attack methods in order to acquire administrative privileges and issue commands remotely. This grants the attacker the ability to modify, create, delete and launch files as well as granting him the ability to run more scripts, executables or shell commands.

    December 21-27, 2020 YOUR CHECK POINT THREAT INTELLIGENCE REPORT TOP ATTACKS AND BREACHES Lazarus group, an APT affiliated with North Korea, has targeted two healthcare entities – Ministry of Health and a pharmaceutical company involved in a COVID-19 vaccine development, probably in order to collect information about the advancements in the pandemic research. Microsoft software resellers have been leveraged by hackers to hack into Microsoft Office 365 customers, including security provider CrowdStrike, who was unsuccessfully attacked. Researchers suspect that the hacking group behind it is the same Russia-based group behind the SolarWinds supply-chain attack. New spam campaign has been delivering the Dridex banking Trojan using fake Amazon Gift Cards distributed via email. The email offers victims a link to a $100 gift certificate and features the original Amazon logo. Check Point Anti-Virus and Anti-Bot provide protection against this threat (Banking.Win32.Dridex; Trojan.Win32.Dridex) Emotet has resumed its attack activities on Christmas eve, after a two-month break, in a campaign targeting over 100,000 users per day. The botnet has updated its payloads, improved detection evasion capabilities and changed its malicious macro document to disguise the payload installation flow. Check Point SandBlast and Anti-Bot provide protection against this threat (Trojan.Win32.Emotet) Livecoin, a Russian cryptocurrency exchange, has been breached on Christmas eve. Attackers managed to gain control over some of the exchange servers and modified the exchange rates.
