A database of 1.4 billion Leaked From Biggest Spam Network


A database of 1.4 billion email addresses combined with real names, IP addresses, and often physical address has been exposed in what appears to be one the largest data breach of this year.

What’s worrisome? There are high chances that you, or at least someone you know, is affected by this latest data breach.

The database contains sensitive information about the company’s operations, including nearly 1.4 Billion user records, which was left completely exposed to anyone – even without any username or password.

According to MacKeeper security researcher Vickery, RCM, which claims to be a legitimate marketing firm, is responsible for sending around a billion unwanted messages per day.

Besides exposing more than a billion email addresses, real names, IP addresses and, in some cases, physical addresses, the leak exposed many documents that revealed the inner workings of RCM’s spam operation.

“The situation presents a tangible threat to online privacy and security as it involves a database of 1.4bn email accounts combined with real names, user IP addresses, and often physical address,” Vickery said. “Chances are that you, or at least someone you know, is affected.”

Vickery wasn’t able to fully verify the leak but said he discovered addresses he knew were accurate in the database.

Illegal Hacking Techniques Used by RCM

The company employed many illegal hacking techniques to target as many users as possible. One of the primary hacking methods described by the researchers is the Slowloris attacks, a method designed to cripple a web server rather than subvert it in this manner.

“[Slowloris is] a technique in which the spammer seeks to open as many connections as possible between themselves and a Gmail server,” Vickery writes in a blog post published today.

“This is done by purposefully configuring your own machine to send response packets extremely slowly, and in a fragmented manner, while constantly requesting more connections.”

The researchers have reported that details of RSM’s operations and its abusive scripts and techniques have been sent to Microsoft, Apple, Salted Hash, Spamhaus, and others affected parties.

Meanwhile, the researchers have also notified law enforcement agencies, which they says, have expressed keen interest in the matter.
