Was An IPMI Flaw Behind 300Gbps DDoS Attack? – ComputerworldUK.com

Computerworld UK has an interesting story that digs into a massive, 300 Gbps DDoS attack that used a flaw in the IPMI protocol to compromise 100,000 unpatched servers, which were then used to send junk traffic to the victim site. The attack was documented by the security firm VeriSign in its quarterly threat report. The flaw, in the Intelligent Platform Management Interface (IPMI) is a well-documented security hole that affects a wide range of devices. The attack in question took place in June and targeted what Verisign described as a content delivery network (CDN) in the media and entertainment sector. The attack combined a variety of techniques, including SYN, TCP and UDP protocols to flood a target data center. The attacks reached a peak traffic volume 300 Gbps and lasted more than a day, prompting Verisign to balance the load across its global network. Verisign attributed the massive volume of the attack to a botnet made up […]

DDoS Attacks Hit Cloud Apps Evernote, Feedly

Large-scale attacks knocked two prominent, web-based services offline late Tuesday, as cyber criminals attempted extort money from the owners of news aggregation site Feedly and the hosted productivity tool Evernote. Feedly – a web site that pulls together news feeds from across the web – remained unreachable early Wednesday, while Evernote was back online. Both companies issued statements confirming that they were the victims of a massive distributed denial of service (DDoS) attack. “We’re actively working to neutralize a denial of service attack. You may experience problems accessing your Evernote while we resolve this,” read a message sent from Evernote’s Twitter account Tuesday evening at around 8:00 PM Eastern Time. And, around 5:00 AM Eastern on Wednesday, Feedly posted a blog entry that reads: “Criminals are attacking feedly (sp) with a distributed denial of service attack (DDoS). The attacker is trying to extort us money to make it stop. We refused to give […]

Akamai: New DoS Tool Leads To Resurgence of SNMP Attacks

The security firm Akamai issued an advisory to customers on Thursday warning that a new software tool for managing distributed denial of service (DDoS) attacks was leading to a resurgence in large-scale attacks that use Simple Network Management Protocol (SNMP) traffic to overwhelm web sites.   The Threat Advisory (reg wall) was issued by Akamai’s Prolexic Security Engineering and Response Team (or PLXsert). According to the advisory, Akamai began noticing a resurgence in DDoS attacks using SNMP on April 11. The company said that firms in industry verticals including consumer goods, gaming, online hosting and Software-as-a-Service and non-profits had all been targeted.   [Read more Security Ledger coverage of DDoS attacks here.] The company has identified new- and updated tools in the cyber underground, including one dubbed SNMP Reflector – that are enabling the attacks. Simple Network Management Protocol (SNMP) is a protocol that is used for managing devices on a network including […]

Mobile Devices Taking Part In Enterprise DDoS Attacks?

Mobile phones have long been on the radar for enterprises concerned about data loss and the spread of malicious code. But a report from the firm Prolexic suggests that they may also be taking part in massive denial of service (DoS) attacks against enterprise networks. The firm Prolexic said that data it collected in the final quarter of 2013 suggests that mobile devices are playing a growing role in distributed DoS (or DDoS) attacks against the firm’s enterprise customers. “Malicious actors now carry a powerful attack tool in the palm of their hands, which requires minimal skill to use,” said Stuart Scholly, president of Prolexic, in a statement. [Read more Security Ledger coverage of Denial of Services Attacks.]   Infecting unwitting victims with a malicious program is a common method used by botnet operators whose platforms are behind many large-scaled DDoS attacks. But Scholly said that mobile devices and mobile DDoS […]

Cyberbunker Owner Arrested In Spain, Rolled In Mobile DDoS Van

As the saying goes: “If the van’s a DoS’in, don’t come a knock’in.” Or something like that. Alas, for  a man believed to be the controversial owner of the Dutch bulletproof hosting firm Cyberbunker, the authorities did “come a knock’in,” arresting the individual who is believed to be responsible for the world’s largest distributed denial of service (DDoS) attack. In a statement on Sunday, the Spanish Ministry of the Interior released a statement saying that National Police agents arrested the man responsible for the attacks in response to a European arrest warrant stemming from an investigation begun by Dutch authorities. The suspect was not named, but was described as a 35 year-old from Alkmaar (Netherlands) who was apprehended while  traveling in a van equipped with computer equipment and a range of antennas and used as a mobile office. The man is believed to be Sven Kamphuis, the owner and manager of Dutch hosting firm […]
