Avast researchers have discovered hacked Facebook business pages spreading a password stealer called Redline Stealer, which is capable of stealing passwords and downloading further malware. The malware is available for purchase on the dark web for about $100 to $150, making it difficult to pinpoint a particular group or person hacking these accounts.
Check all your android and iOS devices, mobile browser, and even a different browser on your computer. And, if you find that you are logged in elsewhere, then you can reset the Facebook password without any need for a security code.
The easiest method is sticking to two-factor authentication using Google Authenticator (GA). To log in to Facebook, you will need your password and a six-digit code from GA. Without the GA code, you can't log into your Facebook account.

Think twice before clicking or download anything from Facebook. The links provided might contain viruses, malware, or even malicious software. If you visit those links, most of your data such as your email, password, and personal information will be harvested by whoever planted that link on your timeline.
Koobface is a worm that works by spamming the contacts of an infected user with messages, such as "Check out this video", directing them to a third-party site hosting malware. Prospective marks are invited to download an "audio code" to view the supposed video clip. This software update contains the malware payload, which activates if executed on a Windows machine, restarting the whole cycle of infection. The malware creates a backdoor on compromised machines, allowing the download of Trojans and other nasty under the control of hackers.
Enterprise security is focused on data center, networking, and web server operations in practice, but technically begins with human resources. Social engineering is the root cause of as many as two-thirds of all successful hacking attacks according to some security researchers. In social engineering attacks, weaknesses in human nature, employee integrity, or personal gullibility are exploited by attackers to gain access to a network or data resources. Phishing attacks via email encourage employees to click on links that download and install malware. In Vishing (voice or VoIP phishing) attacks, hackers exploit voice conversations over the telephone with various employees to attain insider information that leads to a compromise in network security such as password information. Smishing (SMS phishing), baiting, spearfishing, and water holing are all related hacking techniques based on social engineering processes. These attack vectors can compromise even the most robust network security systems and can only be countered through increased employee awareness through training, vetting, and screening.
Automated hacking attacks are script-driven and target data center resources such as web servers and online applications on a continual basis through input entry points such as login screens, contact forms, search-to-database queries, and backend administration processes. Common examples of script bot attacks are MySQL injection hacks and cross-site scripting exploits. The ability to send code to a server through unsecured forms can lead to the loss of an entire database including all of the table information, passwords, and sensitive customer financial data. Code injection hacks are different from password cracking which can lead to full administration access by a hacker or the ability to establish backdoors to a server through FTP and the command line. Successful hackers typically spend 30 to 90 days in reconnaissance of a compromised network system with internal access before beginning the process of transferring database information or installing malicious remote code.
The use of encryption on data transfers and the establishment of firewall settings for authorized user access are the two most fundamental aspects of enterprise security after physical access constraints. Most platforms with user sign-on systems now include lock-out procedures that cut off users after 5 or more incorrect password logins to prevent cracking attacks. Unidentified login attempts that take place repeatedly from a single IP address can be mitigated through IP blocking. Firewall software integrates with anti-virus scanning that matches data packet transmissions with known malware signatures in real-time to identify harmful files and prevent the accidental installation of viruses, worms, and trojans via phishing attacks or downloads. Web Application Firewalls (WAFs) can be installed that add an extra layer of protection to web forms to prevent cross-site scripting and MySQL injection attacks. Anti-virus software from vendors like Symantec, McAfee, Trend Micro, Kaspersky, Bitdefender, etc. are essential aspects of enterprise security today. Many enterprise companies also employ the services of a CDN to recognize and prevent DDoS attacks in production. 2b1af7f3a8
