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 […]

Gameover Not The End: Zeus Malware Still Threatens Fortune 500

Prolexic, a division of Akamai, issued an advisory to Fortune 500 firms on Monday about what it calls “a high-risk threat of continued breaches from the Zeus framework.” The company’s Security Engineering & Response Team (PLXsert) said on Monday that it has observed new payloads from the Zeus crimeware kit in the wild, and that networks of Fortune 500 companies are a prime target. Cyber crime groups are using Zeus to steal login credentials and gain access to web-based enterprise applications, as well as online banking accounts, Akamai warned. “The Zeus framework is a powerhouse crimeware kit that enterprises need to know about to better defend against it,” said Stuart Scholly, senior vice president and general manager, Security Business Unit, Akamai, in a statement. “It’s hard to detect, easy to use, and flexible – and it’s being used to breach enterprises across multiple industries.” A variant of Zeus, Gameover, was the subject […]

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.

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 […]
