Attack rates are increasing across the board

Finance and technology are the sectors most resilient to cyber intrusions, new research from Vectra Networks has found. The company released the results of its Post-Intrusion Report, based on data from a sample set of nearly 200 of its enterprise customers. They looked at the prevalence of strategic phases of the attack lifecycle: command-and-control (C&C), reconnaissance, lateral movement, botnet, and exfiltration attacker behaviours across thirteen industries. Over 90 days (January-March 2017), the company monitored 2,145,708 … More ?

Stealthy DDoS attacks distract from more destructive security threats

The greatest DDoS risk for organisations is the barrage of short, low volume attacks which mask more serious network intrusions. Despite several headline-dominating, high-volume DDoS attacks over the past year, the vast majority (98%) of the DDoS attack attempts against Corero customers during Q1 2017 were less than 10 Gbps per second in volume. In addition, almost three quarters (71%) of the attacks mitigated by Corero lasted 10 minutes or less. Due to their small … More ?

8 RCE, DoS holes in Microsoft Malware Protection Engine plugged

After the discovery and the fixing of a “crazy bad” remote code execution flaw in the Microsoft Malware Protection Engine earlier this month, now comes another MMPE security update that plugs eight flaws that could lead to either remote code execution or to denial of service. Given that the Microsoft Malware Protection Engine powers a number of Microsoft antimalware software, DoS vulnerabilities should be considered serious, since a successfully exploited vulnerability could prevent the MMPE … More ?

There’s now a WannaCry decryptor tool for most Windows versions

As the criminals behind the WannaCry ransomware are trying to make it work again, security researchers have created tools for decrypting files encrypted by it. DDoS attacks against the killswitch domains Since researcher Marcus Hutchins (aka MalwareTech) registered a (previously non-existent) killswitch domain for the malware and stopped its onslaught, the domain has been under attack by Mirai-powered botnets.

DDoS attacks: $100,000 per hour is at risk during peak revenue generation periods

Neustar and Harris Interactive conducted global, independent research of 1,010 directors, managers, CISOs, CSOs, CTOs, and other c-suite executives to find out how DDoS attacks affect their organizations and what measures are in place to counter these threats. The respondents span many industries, including technology, financial services, retail, healthcare and energy. “DDoS attacks are the zeitgeist of today’s Internet,” said Barrett Lyon, pioneer of the DDoS defense industry and Head of Research and Development at … More ?

How to securely deploy medical devices within a healthcare facility

The risks insecure medical devices pose to patient safety are no longer just theoretical, and compromised electronic health records may haunt patients forever. A surgical robot, pacemaker, or other life critical device being rendered non-functional would give a whole new, and wholly undesirable, meaning to denial of service. Malware like MEDJACK has been used to infect medical devices and use them as staging grounds to attack medical records systems. IoT ransomware is on the rise … More ?

Hajime IoT worm infects devices to head off Mirai

Mirai is the name of the worm that has taken control of many IoT devices around the world and used them to mount DDoS attacks, the most high-profile of which was directed against US-based DNS provider Dyn and resulted in many websites and online services being inaccessible for hours on end. Its source code was leaked by the author, which lead to the creation of more botnets, and an increased fear that we’ll soon witness … More ?

CLDAP reflection attacks generate up to 24 Gbps of traffic

Akamai researchers Jose Arteaga and Wilber Majia have identified a new Connection-less Lightweight Directory Access Protocol (CLDAP) reflection and amplification method. CLDAP query packet Akamai’s Security Intelligence Response Team (SIRT) has observed this attack vector producing DDoS attacks consistently exceeding 1 Gbps, comparable to DNS reflection attacks. CLDAP Unlike other reflection-based vectors, where compromised hosts may number in the millions, the observed CLDAP amplification factor has been able to produce significant attack bandwidth with significantly … More ?

IoT devices under attack: Amnesia hijacks, BrickerBot destroys

Every hour of every day, computer systems and IoT devices are under attack by bots trying to recruit them into growing botnets. Security researchers have recently highlighted two of these threats coming after Linux- and BusyBox-based systems and devices. Amnesia A year after security researcher Rotem Kerner discovered a remote code execution vulnerability that affected digital video recorders (DVRs) manufactured by Chinese company TVT Digital and sold by more than 70 different vendors around the … More ?
