Juiced: DDoS Attacks 700 Percent Stronger, Iran Joins Top Source Countries

Denial of Service attacks are experiencing a surge in power and duration in the first months of 2013, with Iran joining China and The United States as a top source of the crippling online attacks. The power of distributed denial of service (or DDos) attacks – measured in packets per second – jumped 718 percent in the first three months of 2013, compared to the final three months of 2012, the security firm Prolexic reported on Wednesday. The average bandwidth used in DD0S attacks reached 32.4 million packets per second, overwhelming Internet service providers (ISPs), carriers and content delivery networks designed to mitigate the effects of sudden Internet traffic surges. The data comes from Prolexic’s DD0S Report for the first quarter of 2013. That firm, based in Hollywood, Florida, has become a go-to firm for companies that find their web sites on the receiving end of DDoS attacks. The average attack bandwidth totaled […]

Botnet Of Embedded Devices Used To Map Internet

Botnets are mostly linked with spam e-mail campaigns, denial of service attacks and data theft. But global networks of compromised hosts can be used for a variety of ends – not all of them malicious. That was the idea behind “Internet Census 2012,” a stealth project by an unnamed and unknown researcher/hacker to map the entire IPV4 Internet address space using a massive network of compromised devices. The results, published in the form of a research paper, underscore the problem of  unsecured embedded devices, including set top boxes, home routers and critical infrastructure, with the hacker able to locate and compromise these systems, creating a botnet of more than 420,000 nodes. According to a copy of the report, the project grew out of an experiment to locate unprotected devices online using nmap, the open source scanning tool. By compromising each vulnerable host and then enlisting it to scan for other […]
