130,000 Avtech IP cameras, DVRs can be easily roped into IoT botnets

Security researcher Gergely Eberhardt has unearthed over dozen of vulnerabilities in most IP cameras, NVRs and DVRs by Taiwanese manufacturer Avtech, including things like plaintext storage of administrative password and authentication bypass flaws. Eberhardt, who works for Hungarian security testing outfit Search Lab, says a final tally would likely be even higher, as these vulnerabilities were found within a short period of time and the research was done without a systematic approach. According to the … More ?

IoT-based DDoS attacks on the rise

Cybercriminal networks are increasingly taking advantage of lax Internet of Things device security to spread malware and create zombie networks, or botnets, unbeknownst to their device owners. When lax security becomes a huge problem Symantec’s Security Response team has discovered that cybercriminals are hijacking home networks and everyday consumer connected devices to help carry out DDoS attacks on more profitable targets, usually large companies. To succeed, they need cheap bandwidth and get it by stitching … More ?

Spam is once again on the rise

Spam volume is back to mid-2010 heights, and Cisco Talos researchers say that the Necurs botnet is partly to blame. “Many of the host IPs sending Necurs’ spam have been infected for more than two years. To help keep the full scope of the botnet hidden, Necurs will only send spam from a subset of its minions. An infected host might be used for two to three days, and then sometimes not again for two … More ?

Business still ill-prepared to handle modern DDoS attacks

In September 1996, New York City’s original ISP, Panix, was hit by a SYN flood denial of service attack that took them offline for several days. At a time when only 20 million Americans were online, this was one of the first high profile examples of the growing importance of network and service availability. It also demonstrated how fragile internet infrastructure was at the time. According to an advisory from Carnegie Melon’s CERT, “There is, … More ?

US 911 emergency system can be crippled by a mobile botnet

What would it take for attackers to significantly disrupt the 911 emergency system across the US? According to researchers from Ben-Gurion Univerisity of the Negev’s Cyber-Security Research Center, as little as 200,000 compromised mobile phones located throughout the country. The phones, made to repeatedly place calls to the 911 service, would effect a denial-of-service attack that would made one third (33%) of legitimate callers give up on reaching it. And if the number of those … More ?
