Gameover ZeuS

There is evidence he also was using his own botnet kit or at least taking a fee to set up instances of it on behalf of buyers. In late 2009, security researchers had tracked dozens of Zeus control servers

the samples were downloaded from a compromised website located in the United States... Gameover Zeus has also been distributed by the Blackhole and Magnitude exploit kits.

Infection Method Blackhole Exploit Kit • Specific configuration for Gameover Zeus

The Necurs botnet is one of the largest networks in the spam email threat ecosystem... During a 58-day period in our investigation, for example, we observed that one Necurs-infected computer sent a total of 3.8 million spam emails to over 40.6 million potential victims.

GOZ typically infects a machine via a phishing attack and other bogus emails.

Some of the most commonly used commands used by attackers are: user_execute <url> ... The user_execute command was used specifically for CryptoLocker installations too

the government believes is responsible for building and distributing the ZeuS banking Trojan . Bogachev is thought to be a core architect of ZeuS, a malware strain that has been used to steal hundreds of millions of dollars from bank accounts

The principal purpose of GOZ is to capture banking credentials from infected computers. One means by which GOZ accomplishes this is through ... attacks, in which GOZ intercepts sensitive information victims transmit from their computers.

even in its early days, the malware could receive dynamic configuration files, use web injections to steal money

The principal purpose of the botnet is to capture banking credentials from infected computers.

The Operation Technology • Regular expression support

During our research, we found a large amount of search queries which were executed on the victim systems. The search queries consisted of a number of keywords... focused on locating “government classified” material

Espionage ... Targeting government and intelligence agencies ... foreign intelligence ... counter intelligence ... top secret

The token-grabber attack in peer-to-peer ZeuS... The victim would see a normal, or almost normal, login page of their bank... During the victim being on hold, the browser would continuously poll the backend to check if new questions were available to ask the victim.

Proxy Nodes • Route C2 communication • Stolen data

Dridex has been able to escape justice for so long by hiding its main command-and-control (C&C) servers behind proxying layers.

It uses a tiered, decentralized system of intermediary proxies and strong encryption to hide the location of servers that the botnet masters use to control the crime machine.

By early 2015, Dridex implemented a kind of P2P network... some peers (supernodes) had access to the C&C and forwarded requests from other network nodes to it.

The Necurs botnet has historically been used to deliver a torrent of other high profile cyber threats to the world, including the GameOver Zeus and Dridex banking trojans, Locky ransomware and, more recently, the banking trojan turned all purpose cybercrime-as-a-service, Trickbot.

The Operation Technology • Domain generation algorithm (DGA) ... Controlling the DGA Layer • Reverse-engineered and reimplemented Domain Generation Algorithm

It uses a tiered, decentralized system of intermediary proxies and strong encryption to hide the location of servers that the botnet masters use to control the crime machine.

The Gameover Zeus botnet operates silently on victim computers by directing those computers to reach out to receive commands from other computers in the botnet and to funnel stolen banking credentials back to the criminals who control the botnet.

He also launched ransomware attacks years before they were a runaway hit with criminals.

Bogachev is accused of running the Gameover Zeus botnet, a massive crime machine of 500,000 to 1 million infected PCs that was used for large DDoS attacks
