Many of the Instagram users Email Address Changed and reportedly Instagram Hacked.


Instagram users suddenly log out of their accounts and when they try to log in, they find all the personal info has been changed, Mashable reported.
Some of the user’s profile pic has been changed to a Disney or Pixar character and the E-mail id changed to a Russian domain. Even they bypass two-factor authentication and turned off by hackers.
There are lot of Instagram users are asking on Twitter to recover their account. But there is no reply from an Instagram official.
The extra security measure didn’t protect Chris Woznicki, who was using two-factor authentication at the time his account was hacked 10 days ago. Woznicki says Instagram sent him security emails notifying him the email address on his account had been changed (once again, to a .ru address) and 2FA had been disabled. But by the time he saw the messages, it was too late and he had already lost access to his account.

What is the issue?

Possibly, the hackers found Zero-Day Vulnerability, which might be possible to change the Instagram user profile. Instagram users have locked out, hackers changed their username and mobile phone and email address with a .ru Russian domain.

Eavesdropping on an attack where cybercriminals try to steal your private information and transmitted through unsecured network communication.

Eavesdropping is secretly or stealthily listening to the private conversation or communications of others without their consent. Network eavesdropping is a network layer attack that focuses on capturing small packets from the network transmitted by other computers and reading the data content in search of any type of information. This type of network attack is generally one of the most effective as a lack of encryption services are used. It is also linked to the collection of metadata.
Eavesdropping is an unauthorized digital communication, real-time interception of a private communication, such as phone calls, instant message, video conference or fax transmission. As simple we can explain, it is the act of intercepting digital communication between two points as part of Sniffing.
Cyber attackers can sniff the network and get the record output of sensitive data from insecure networks. The packets are encrypted, but it can view by using some cryptographic tools and able to intercept for getting private information such as your password, credit card details from the unsecured website that does not use SSL encryption.

Methods

Data sniffing- in the context of network security, corresponds to theft or interception of data by capturing the network traffic using a sniffer (an application aimed at capturing network packets). When data is transmitted across networks, if the data packets are not encrypted, the data within the network packet can be read using a sniffer.
Using a sniffer application, an attacker can analyze the network and gain information to eventually cause the network to crash or to become corrupted, or read the communications happening across the network.
Sniffing attacks can be compared to a tapping of phone wires and get to know about the conversation, and for this reason, it is also referred to as wiretapping applied to computer networks. Using sniffing tools, attackers can sniff sensitive information from a network, including Email traffic (SMTP, POP, IMAP traffic), Web traffic (HTTP), FTP traffic (Telnet authentication, FTP Passwords, SMB, NFS) and many more.
The Packet Sniffer utility usually sniffs the network data without making any modifications in the network’s packets. Packet sniffers can just watch, display, and log the traffic, and this information can be accessed by the attacker.

Man In The Middle-

Man-in-the-middle attack (MITM) is an attack where the attacker secretly relays and possibly alters the communication between two parties who believe they are directly communicating with each other.
Eavesdropping is one of the example of man-in-the-middle attacks, in which the attacker makes independent connections with the victims and relays messages between them to make them believe they are talking directly to each other over a private connection, when in fact the entire conversation is controlled by the attacker.
The attacker must be able to intercept all relevant messages passing between the two victims and inject new ones. This is straightforward in many circumstances; for example, an attacker within reception range of an unencrypted wireless access point (Wi-Fi) could insert himself as a man-in-the-middle.

Impact of Eavesdropping Attack?

  • By using someone’s bank account info to make unauthorized purchases or to transfer money to the cybercriminal account.
  • By stealing person identity, in terms of their private information including Social security numbers (SSN), Home address, etc
  • Eavesdropping attack is generally performed by black hat hackers. However, government security agencies have also been connected.

Prevention

  1. To prevent Eavesdropping network attacks, do not use applications that are using insecure protocols, like basic HTTP authentication, File Transfer Protocol (FTP), and Telnet.
  2. Instead, secure protocols such as HTTPS, Secure File Transfer Protocol (SFTP), and Secure Shell (SSH) should be preferred.
  3. Use Top VPN (Virtual Private Networks) to secure your network. In case there is a necessity for using any insecure protocol in any application, all the data transmission should be encrypted.
  4. Use Internet Security software instead of Antivirus solutions. It can protect you from Network threat activities.
  5. Do not use Public Wi-Fi network.

urrently, there are many Web Application Security Scanners but we are confused to choose the best one among them.

What is Web Application Security Scanner?

Web Application Security Scanner is a software program which communicates with a web application through the web front-end in order to identify potential security vulnerabilities in the web application and architectural weaknesses. It performs a black-box test. Unlike source code scanners, web application scanners don’t have access to the source code and therefore detect vulnerabilities by actually performing attacks.
A web application security scanner facilitates the automated review of a web application with the expressed purpose of discovering security vulnerabilities, and are required to comply with various regulatory requirements. Web application scanners can look for a wide variety of vulnerabilities, such as input/output validation: (e.g. cross-site scripting and SQL injection), specific application problems and server configuration mistakes.
Web Application software can be used by a White Hat Hacker as well as Black Hat Hacker.
White Hat Hacker reports the vulnerability to a targeted or victim company, whereas Black Hat Hacker could use the vulnerability for malicious purposes. White Hat Hackers mostly use Web Application Security Scanners which are briefly explained below.
So most demanding software for Web Application Security Scanner is theNetsparker.
Now Audit Your Websites with Netsparker Web Application Security Scanner in easy way.
Netsparker finds and reports web application vulnerabilities such as SQL Injection and Cross-site Scripting (XSS) in all types of web applications, regardless of the platform and technology they are built with. Netsparker’s unique and dead accurate Proof-Based ScanningTM technology does not just report vulnerabilities, it also produces a Proof of Concept to confirm they are not false positives. Freeing you from having to double check the identified vulnerabilities.

Netsparker is available in two versions i.e. Desktop Scanner and a Cloud Scanner.

Netsparker Desktop Scanner-

Netsparker Desktop scanner
Netsparker Desktop is a fully automated, easy to use and dead accurate web application security scanner. It helps professionals automatically identify security flaws in their web applications, web services and APIs.

Yes, you heard it right, there are 42 Email ID and passwords uploaded on Free web hosting service Kayo.

According to the report, a collection of almost 42 million email address and plain text password pairs was uploaded to the anonymous file sharing service kayo.moe. The operator of the service contacted Have I Been Pwned (HIBP) to report the data which, upon further investigation, turned out to be a large credential stuffing list.
Kayo is a free and anonymous hosting service. The operator of Kayo reached out to TroyHunt for the report of a collection of files uploaded to the site. Hope you know about TroyHunt, he runs HaveIBeenPwned service, where a user can check their account that it has been compromised in a data breach or not.
So according to TroyHunt blog, Kayo sent the 1.8 GB data including 755 files to contain personal data breach with Email ID username and password in credential attacks. These attacks typically take data from multiple breaches then combine them into a single unified list so that they can be used in account takeover attempts on other services.
Leaked Username and Passwords

What is the Credential Stuffing Attack?

Credential stuffing is the automated injection of breached username/password pairs in order to fraudulently gain access to user accounts. This is a subset of the brute force attack category: large numbers of spilled credentials are automatically entered into websites until they are potentially matched to an existing account, which the attacker can then hijack for their own purposes.
Credential stuffing is a new form of attack to accomplish account takeover through automated web injection. Credential stuffing is related to the breaching of databases; both accomplish account takeover. Credential stuffing is an emerging threat.
Credential stuffing is one of the most common techniques used to take-over user accounts.
Credential stuffing is dangerous to both consumers and enterprises because of the ripple effects of these breaches. For more information on this please reference the Examples section showing the connected chain of events from one breach to another through credential stuffing.

What are the contents in leaked data?

There are a variety of files with logs, credit cards data and some Spotify details.
Spotify details? don’t worry it doesn’t indicate a Spotify breach. So, all the data is a combination of sources intended to be used for malicious purpose.
Troy determined that 89 percent of passwords are already in Have I Been Pwned (HIBP) collection. The filenames in the database do not point to a particular source because there is no single pattern for the breaches they appeared in. Also the data showed 91 percent of the passwords were already in Pwned Passwords, here you can check yours.

Protection

  • The database trading is highly activated by cyber-criminals. HOC recommends you to generate unique passwords for each site you signup.
  • Do not keep the same password, use different passwords for different accounts.
  • Always use two-factor authentication, it helps to protect such kinds of attacks.
Also, HIBP service partnered with Mozilla browser. Firefox Monitor will be integrating with HIBP and also partnered with 1Password service.
Troy had announced in March 2018 that he would partner with 1Password. It is password manager which provides a place for users to store various passwords in one place. In the blog, he said, users can search HIBP directly from 1Password watchtower feature in the web version.
1Password is using Have I Been Pwned (HIBP) to find compromise accounts based on E-mail address. It works without sharing your E-mail address with others.

Bad month for security people in companies dealing with email marketing campaigns.

The Security researcher Bob has shared the detail with us. He found the information by scanning the database server and find the right path to access the data. He explained in the following article.
On Monday morning, Sept 17th, I have discovered a huge customer database containing 11 million records that included personal details, such as email, full name, gender, physical address (zip code, state, city of residence).
The data was available from an unprotected MongoDB instance set up on Grupo-SMS hosting infrastructure, and could be accessed by anyone from Sept 13th on (when Shodan last indexed it).
The 43.5GB large dataset contained 10,999,535 email addresses, all Yahoo-based. Apart from customer personal information, the database also included DNS details about the email status (sent successfully or not), that showed if the email went through, and server response.

The origin of data remains unknown, as database name itself did not give any clues as of potential owner.

Also, data did not contain any administrator emails, system logs or host information. One hint was given in the description of the lists in which a particular email was part of – “Yahoo_090618_ SaverSpy”.
SaverSpy (powered by Coupons.com) are websites that provide printable and digital discount coupons for a wide range of products.
I have tried to contact both organizations about the potential data breach but received no answer by the time of publishing. However, database has been taken offline shortly after notification email sent and now unreachable.
Interestingly, that MongoDB in question has already been tagged as ‘Compromised’ in Shodan and contained ‘Warning’ database with ‘Readme’ collection and ransom note demanding 0.4 BTC for recovering the data. However, at the time of discovery, all data were intact. I assume this is a result of failed script scenario used by crooks (and pure luck for the database owners).
Like in my previous discovery of Veeam, the information from database (e-mails with personal details) was a pure gold for malicious actors such as spammers, scammers, phishers of all kinds – surfaced online due to a human error or default settings misconfiguration (which is for me the same kind of a mistake).
