A new botnet was identified, threatening Twitter. Î’otnet is a network of computers under the control of a malicious software program. The malicious program runs silently on a compromised computer, until the central computer (the hacker) gives a command to perform an "attack." Attacks come in the form of spam, denial of service attacks, or infecting other machines on a network. The new botnet threatening Twitter is called "TwitterNet Builder" and performs a variety of actions, including the installation of software or a distributed denial-of-service attack from Twitter accounts. The attack works like this: When the computer is infected by "TwitterNet Builder", the attacker is able to write commands that instruct the machine what information to take from a specified Twitter account. The good news is that this attack is not really effective on private accounts. This means that any attempt for hiding commands on a private Twitter page, is worthless and as a fact helps Twitter to identify easier the intruder. Source: Trust-IT
