Serious Crypto-Flaw Lets Hackers Recover Private RSA Keys Used in Billions of Devices

Serious Crypto-Flaw Lets Hackers Recover Private RSA Keys Used in Billions of Devices

Oct 17, 2017
If you think KRACK attack for WiFi is the worst vulnerability of this year, then hold on… ...we have got another one for you which is even worse. Microsoft, Google, Lenovo, HP and Fujitsu are warning their customers of a potentially serious vulnerability in widely used RSA cryptographic library produced by German semiconductor manufacturer Infineon Technologies. It's noteworthy that this crypto-related vulnerability (CVE-2017-15361) doesn't affect elliptic-curve cryptography and the encryption standard itself, rather it resides in the implementation of RSA key pair generation by Infineon's Trusted Platform Module (TPM). Infineon's Trusted Platform Module (TPM) is a widely-used, dedicated microcontroller designed to secure hardware by integrating cryptographic keys into devices and is used for secured crypto processes. This 5-year-old algorithmic vulnerability was discovered by security researchers at Masaryk University in the Czech Republic, who have relea
Hackers Use New Flash Zero-Day Exploit to Distribute FinFisher Spyware

Hackers Use New Flash Zero-Day Exploit to Distribute FinFisher Spyware

Oct 16, 2017
FinSpy —the infamous surveillance malware is back and infecting high-profile targets using a new Adobe Flash zero-day exploit delivered through Microsoft Office documents. Security researchers from Kaspersky Labs have discovered a new zero-day remote code execution vulnerability in Adobe Flash, which was being actively exploited in the wild by a group of advanced persistent threat actors, known as BlackOasis . The critical type confusion vulnerability, tracked as CVE-2017-11292 , could lead to code execution and affects Flash Player 21.0.0.226 for major operating systems including Windows, Macintosh, Linux and Chrome OS. Researchers say BlackOasis is the same group of attackers which were also responsible for exploiting another zero-day vulnerability ( CVE-2017-8759 ) discovered by FireEye researchers in September 2017. Also, the final FinSpy payload in the current attacks exploiting Flash zero-day (CVE-2017-11292) shares the same command and control (C&C) server as the

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica
Yet Another Linux Kernel Privilege-Escalation Bug Discovered

Yet Another Linux Kernel Privilege-Escalation Bug Discovered

Oct 16, 2017
Security researchers have discovered a new privilege-escalation vulnerability in Linux kernel that could allow a local attacker to execute code on the affected systems with elevated privileges. Discovered by Venustech ADLab (Active-Defense Lab) researchers, the Linux kernel vulnerability (CVE-2017-15265) is due to a use-after-free memory error in the Advanced Linux Sound Architecture (ALSA) sequencer interface of the affected application. The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the Linux operating system, and also bundles a userspace driven library for application developers, enabling direct (kernel) interaction with sound devices through ALSA libraries. Successful exploitation of this vulnerability requires an attacker—with local access on the targeted system—to execute a maliciously crafted application on a targeted system, which allows the attacker to elevate his privilege to root on the targeted system, a Cisco advisory warned

How A Drive-by Download Attack Locked Down Entire City for 4 Days

How A Drive-by Download Attack Locked Down Entire City for 4 Days

Oct 16, 2017
We don't really know the pain and cost of a downtime event unless we are directly touched. Be it a flood, electrical failure, ransomware attack or other broad geographic events; we don't know what it is really like to have to restore IT infrastructure unless we have had to do it ourselves. We look at other people's backup and recovery issues and hope we are smarter or clever enough to keep it from happening to us. Recovery from a downtime event includes inconvenience, extra work, embarrassment and yes, real pain. A ransomware attack is a good example. Unitrends—an American company specialised in backup and business continuity solutions—recently shared with us a real cyber-attack incident happened with one of their customers to describe the required steps they took to recover functionality following a CryptoLocker attack against a US city. Also, how it cost city's Governance team days of production and hundreds of man-hours to recover. The Challenge
KRACK Demo: Critical Key Reinstallation Attack Against Widely-Used WPA2 Wi-Fi Protocol

KRACK Demo: Critical Key Reinstallation Attack Against Widely-Used WPA2 Wi-Fi Protocol

Oct 16, 2017
Do you think your wireless network is secure because you're using WPA2 encryption? If yes, think again! Security researchers have discovered several key management vulnerabilities in the core of Wi-Fi Protected Access II (WPA2) protocol that could allow an attacker to hack into your Wi-Fi network and eavesdrop on the Internet communications. WPA2 is a 13-year-old WiFi authentication scheme widely used to secure WiFi connections, but the standard has been compromised, impacting almost all Wi-Fi devices—including in our homes and businesses, along with the networking companies that build them. Dubbed KRACK — Key Reinstallation Attack —the proof-of-concept attack demonstrated by a team of researchers works against all modern protected Wi-Fi networks and can be abused to steal sensitive information like credit card numbers, passwords, chat messages, emails, and photos. Since the weaknesses reside in the Wi-Fi standard itself, and not in the implementations or any individua
Ukraine Police Warns of New NotPetya-Style Large Scale CyberAttack

Ukraine Police Warns of New NotPetya-Style Large Scale CyberAttack

Oct 14, 2017
Remember NotPetya ? The Ransomware that shut down thousands of businesses, organisations and banks in Ukraine as well as different parts of Europe in June this year. Now, Ukrainian government authorities are once again warning its citizens to brace themselves for next wave of "large-scale" NotPetya-like cyber attack. According to a press release published Thursday by the Secret Service of Ukraine (SBU), the next major cyber attack could take place between October 13 and 17 when Ukraine celebrates Defender of Ukraine Day (in Ukrainian: День захисника України, Den' zakhysnyka Ukrayiny). Authorities warn the cyber attack can once again be conducted through a malicious software update against state government institutions and private companies. The attackers of the NotPetya ransomware also used the same tactic—compromising the update mechanism for Ukrainian financial software provider called MeDoc and swapping in a dodgy update including the NotPetya computer v
