“Some typical characteristic in its logged activities have suggested a human’s direct interactive during a session of attacks, supporting facts of the establishment for connection used to conduct TCP forwarding that was manually set.” wrote MMD.Įxclusive – Italian websites under attack

The hackers launched both automated and manual attacks with different characteristics in the way of making connections and performing attack sessions. “we have a recycle-like process for ultimate credential harvesting directed by hackers.” reads MMD. When the attackers steal the credentials from a website then they use them in brute force attacks on other services. MMD included screenshots of most seen abuses against major websites such as PayPal, LinkedIn, Facebook, Gmail, Royal Bank, AT&T, Playstation Store, Playstation Network, eBay, Ubisoft, Sony Entertainment Network, and many others,Īccording to MMD, the hackers harvested a huge quantity of email from major online email services, including Gmail, Yahoo, AOL, Microsoft (Live Mail & Hotmail),, Yandex, etc.

The analysis published by MalwareMustDie includes several PoC codes, the researcher also shared reversed code and traffic analysis, along with mitigation measures. Sending SMTP requests to several email servers (H ereforth is called as “MTA”).Sending HTTP requests to compromised sites to allegedly confirm suspicious activities.Sending HTTP requests to force (brute)authentication in a legitimate sites for user(s) and password(s).Sending invalid HTTP method requests for mod-ssl vulnerabilities with the same purpose as above.Sending malformed HTTP requests to a targeted web server to exploit the service.They aimed for credential launched through several TCP attacks (HTTP/HTTPS or SMTP).”Īttackers are able to launch various forms of attacks mostly aiming HTTP (protocol) with and without SSL. The infrastructure of compromised SSH services and IoT devices are used as front-end cushion for the attack. “The attacker is grabbing credentials from the hack-able targets from their infrastructure” continues MalwareMustDie blog: “They manually perform the attack or daemonized the SSH connectivity to be TCP forwarded through some layers of hack-able SSH accounts to perform the attack. Figure 1: The scheme adopted by a new threatīut let’s give a look at the overall process and the modus operandi of the attackers.
