Its annual threat report cautioned that the rise of IoT, which will yield a projected 20 billion connected devices this year, greatly increases the risks of DDoS attacks, which have grown in frequency and intensity.īut as GitHub’s experience demonstrates, it’s possible to have a plan in place that can lessen the damage and even fend off DDoS attacks when they occur. Luckily, the company had a mitigation strategy in place and quickly switched to routing traffic through its DDoS protection service, foiling the attack.Īccording to Netscout, whose subsidiary Arbor Networks created a map that shows daily DDoS attacks, the company detected 23,000 attacks every day in 2019, on average. According to Wired, the attack measured 1.35 terabits of data per second, and GitHub suffered from outages as a result. However, when attacks are timed and coordinated for maximum impact, Bandwidth’s filing shows that they can a severe impact on a company’s bottom line, especially when attackers target cloud providers that either charge by the hour or need to maintain a nearly perfect uptime otherwise they incur penalties based on ongoing contracts.In 2018, GitHub saw one of the largest DDoS attacks ever recorded. The SEC documents filed last week offer a rare glimpse into the aftermath of DDoS attacks, many of which are often ridiculed as being the work of non-sophisticated threat actors. The company plans to discuss the attack and its impact on revenue in an earnings call on November 8, next week. #BANDWIDTH DDOS ATTACK FULL#“Based on preliminary usage data and currently known information, the company estimates that the impact of the DDoS attack may reduce CPaaS revenue for the full year of 2021 by an amount between $9 million and $12 million, inclusive of the aforementioned $0.7 million revenue impact in the third quarter,” Bandwidth said. In a document filed with the US Securities Excahnge Commission last week, Bandwidth said the attacks were large enough to put a dent in its Q3 revenue of $0.7 million, along with bigger losses expected by the end of the year. by attacking its portal, through which the company provided on-demand server infrastructure to smaller VoIP telephony providers.
