Issue Overview: A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. CVE-2015-02...
Ransomware attacks on Hospitals put Patients at Risk
Just last week, the Federal Bureau of Investigation FBI issued an urgent "Flash" message to the businesses and organisations about the threat of Samsam Ransomware, but the ransomware has already wreaked havoc on some critical infrastructure. MedStar, a non-profit group that runs 10 hospitals in t...
Petya Ransomware Master File Table Encryption
First ransomware locked your desktop. Then it encrypted your files. Not long after, webservers, shared drives and backups were targeted. Now? Introducing Petya, ransomware that targets the Master Boot Record. Spotted in email campaigns sent to human resources offices in German companies, the...
SSL/TLS: Cross-protocol attack on TLS using SSLv2 (DROWN)
A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker could potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack ...

Cisco Prime LAN Management Solution Default Decryption Key Vulnerability
A vulnerability in Cisco Prime LAN Management Solution LMS could allow an authenticated, local attacker to decrypt and access data fields in LMS databases that are used to manage devices in Cisco networks. The vulnerability is due to the presence of a default database decryption key that is share...
OpenSSL: Side channel attack on modular exponentiation
A side-channel attack was found that makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture. An attacker who has the ability to control code in a thread running on the same hyper-threaded core as the victim's thread that is performing decryption, could use this flaw to...
