What is the Heartbleed attack?
The Heartbleed attack works by tricking servers into leaking information stored in their memory. So any information handled by web servers is potentially vulnerable. That includes passwords, credit card numbers, medical records, and the contents of private email or social media messages.
Is Heartbleed still a threat?
The Heartbleed vulnerability was discovered and fixed in 2014, yet today—five years later—there are still unpatched systems. The Heartbleed vulnerability was introduced into the OpenSSL crypto library in 2012. It was discovered and fixed in 2014, yet today—five years later—there are still unpatched systems.
What is Poodle vulnerability?
The POODLE vulnerability lets the attacker eavesdrop on encrypted communication. This means that the attacker can steal confidential data that is transmitted, for example, passwords or session cookies, and then impersonate the user.
What is eternal blue vulnerability?
EternalBlue exploits SMBv1 vulnerabilities to insert malicious data packets and spread malware over the network. The exploit makes use of the way Microsoft Windows handles, or rather mishandles, specially crafted packets from malicious attackers.
What is the freak vulnerability?
The FREAK vulnerability refers to a weakness in the Secure Sockets Layer (SSL)/Transport Layer Security (TLS) protocols caused by the use of ‘export-grade’ encryption. The name stands for ‘Factoring RSA Export Keys’.
What is drown vulnerability?
DROWN, stands for “Decrypting RSA with Obsolete and Weakened eNcryption”, is a serious vulnerability that affects HTTPS and other services that rely on SSL and TLS, some of the essential cryptographic protocols for Internet security.
Is EternalBlue a WannaCry?
EternalBlue has been famously used to spread WannaCry and Petya ransomware. But the exploit can be used to deploy any type of cyberattack, including cryptojacking and worm-like malware.
What vulnerability did WannaCry exploit?
WannaCry ransomware was spreading like a computer worm, laterally across computers by exploiting the Windows SMB vulnerability. Almost 200,000 computers across 150 countries were found to be infected in the attack.
What is SSL freak vulnerability?
Description. The FREAK attack is a SSL/TLS vulnerability that allows attackers to intercept HTTPS connections between vulnerable clients and servers and force them to use ‘export-grade’ cryptography, which can then be decrypted or altered.
What is SSLv2?
SSLv2 is an older implementation of the Secure Sockets Layer protocol. It suffers from a number of security flaws allowing attackers to capture and alter information passed between a client and the server, including the following weaknesses: No protection from against man-in-the-middle attacks during the handshake.
Is Microsoft Azure affected by Heartbleed?
The Heartbleed vulnerability in OpenSSL ( CVE-2014-0160) has received a significant amount of attention recently. While the discovered issue is specific to OpenSSL, many customers are wondering whether this affects Microsoft’s offerings, specifically Microsoft Azure.
How many websites are vulnerable to Heartbleed?
However, Netcraft.com states that ” Half a million widely trusted websites vulnerable to the Heartbleed bug. ” To put it another way, Kelly Jackson Higgins of Darkreading.com wrote that ” 17 percent of SSL-secured websites [are affected].”
Which operating systems are vulnerable to the Heartbleed threat?
Anything running OpenSSL 1.0.1 through 1.0.1f is vulnerable to the Heartbleed threat. An advisory site called heartbleed.com designates these operating systems as being “potentially vulnerable”: Debian Wheezy (stable), OpenSSL 1.0.1e-2+deb7u4 ( click here for the fix )
Is your company’s information at risk from Heartbleed?
Even if you didn’t find any systems vulnerable to Heartbleed, you should still communicate your status to them since they’ll likely have heard of this threat and want to know whether your company – and therefore their information – was at risk.
