However its use of random names and payload makes it more stealthy and dangerous than most of its predecessors. The world’s first Free Cisco Lab at Firewall. So Fizzer is just the latest in a long and ignoble line. In August 2002, the Duload worm used attempted similar propagation tactics.īefore that we had the (awkwardly named) Backdoor.K0wbot.1.3.B and Benjamin worm. In February, the Igloo worm (which falsely promised racy pictures of celebrity nudes) spread through KaZaA. PhotoMiner Worm Spreads via Insecure FTP Servers A worm observed in thousands of attacks this year features sophisticated protection mechanisms that allow it to remain on infected systems for years, GuardiCore security researchers warn. Using P2P networks as a vector for viral propagation has become a popular trick of late. The PhotoMiner worm, identified by researchers at GuardiCore, earns money for its authors by using the resources of infected machines to mine for the Monero cryptocurrency. It's still possible to remove the worm if you get infected but prevention is far easier than cure. AV vendors are in the process of updating signature definitions to recognise Fizzer. To spread via KaZaA, Fizzer creates multiple copies of itself under random names, and places these files in the victim computer's dedicated KaZaA file-sharing folder.

Avoid open unsolicited attachments, even when they appear to come from people you trust, and update AV tools to detect the worm. Next, the worm, in the name of the computer owner, clandestinely sends out infected messages using different subjects, message texts and file attachment names. To avoid infection users are advised to apply standard precautions. When it finds a DB server, the attacker creates an SSH tunnel through the FTP server, which. Using the SSH service on the FTP port, the attacker uses its privileges to map the internal network in search of a DB server.
Running the file infects him with the PhotoMiner worm.In an attempt to foil detection, Fizzer also attempts to shut down an array of widely used anti-virus programs that might be running on a victim's PC.Ī write-up of the worm by Kasperky gives more information. The attacker then shuts down the FTP service and opens an SSH service listening on the same port as the original FTP service. PhotoMiner achieves this by embedding an iframe tag inside each page, with the source attribute set to "Photo.scr", hence the malware's name of Photo-Miner.Īt this point, the iframe prompts the user with a popup, asking if he wants to run the file.

The worm alters the source code of these pages in order to deliver another copy of itself. This is easy since there are over 20.3 million servers with open FTP ports connected to the Internet, and GhostShell has shown Softpedia how easy is to hack them.Īfter PhotoWorm reaches an FTP server, it will scan for public HTML folders, usually used for hosting Web pages. The first stage requires the malware coder to find an infected FTP server to unleash his worm. The infection mechanism is a bit complex.

Advantage is being taken of the way Microsoft Windows DNS Server. PhotoMiner features a multi-stage infection mechanism The W32/Delbot-AI worm (also known as Nirbot or Rinbot) is exploiting an unpatched zero day vulnerability in Microsoft's software. The hackers' worm has been able to exploit the flaw by sending a crafted RPC packet to vulnerable PCs. There are currently two different versions of PhotoMiner spreading over the Internet, but the company says that both function in the same way, with tiny differences. The W32/Delbot-AI worm (also known as Nirbot or Rinbot) is taking advantage of a vulnerability in the way Microsoft Windows DNS Server's Remote Procedure Call (RPC) interface has been implemented. In the meantime, the company found that the worm was created in early December 2015, and received several updates after its January write-up. The worm spreads by scanning the Internet for servers based on Red Hat 6.2 or 7.0-identifying the servers by their release dates-and then attempts to gain access using several methods. Security firm GuardiCore discovered the worm this past January when it also published a quick summary of its abilities. More than a quarter of the third-party apps used in enterprises are risky, and one of the most problematic are connected cloud applications, according to cloud security company CloudLock.
