A week in security (February 5 – February 11)

Last week on Malwarebytes Labs, we featured a new Flash Player zero-day that has been found in recent targeted attacks. And we talked about a new trick to cripple browsers that came out of the hat of tech support scammers. We also covered several methods of stealing cryptocurrencies, including on...

Open Source Static Code Analyser: StaCoAn

StaCoAn is a crossplatform tool which aids developers, bugbounty hunters and ethical hackers performing static code analysis on mobile applications. This tool will look for interesting lines in the code which can contain: Hardcoded credentials API keys URL’s of API’s Decryption keys Major coding...

Weak ElGamal Parameters

PyCrypto uses weak ElGamal cryptography. Due to an incorrect implementation of ElGamal, the Decisional Diffie-Hellman DDH assumption doesn't hold because of the way the key parameters are generated. This allows attackers who have access to the cipher-text to decrypt the messages and potentially...

CVE-2018-5797

An issue was discovered in Extreme Networks ExtremeWireless WiNG 5.x before 5.8.6.9 and 5.9.x before 5.9.1.3. There is an Smintencrypt Hardcoded AES Key that can be used for packet decryption obtaining cleartext credentials by an attacker who has access to a wired port...

Hardcoded credentials

An issue was discovered in Extreme Networks ExtremeWireless WiNG 5.x before 5.8.6.9 and 5.9.x before 5.9.1.3. There is an Smintencrypt Hardcoded AES Key that can be used for packet decryption obtaining cleartext credentials by an attacker who has access to a wired port...

CVE-2018-5797

The CVE-2018-5797 entry concerns Extreme Networks ExtremeWireless WiNG (versions 5.x before 5.8.6.9 and 5.9.x before 5.9.1.3). The root cause is a hardcoded Smint_encrypt AES key which can be used to decrypt packets and obtain cleartext credentials. This affects devices where an attacker has acce...

The Evolution of Ransomware

While many businesses and individual users understand that ransomware isn't a new threat, many don't actually know how long this particular infection style has been utilized by hackers. The first attacks took place more than a decade ago, and since then, ransomware authors have only become more...

Scarab ransomware: new variant changes tactics

The Scarab ransomware was discovered in June 2017. Since then, several variants have been created and discovered in the wild. The most popular or widespread versions were distributed via the Necurs botnet and initially written in Visual C compiled. However, after unpacking, we've found that anoth...

BSA-2018-527

Summary OpenSSL 1.0.2 starting from version 1.0.2b introduced an "error state" mechanism. The intent was that if a fatal error occurred during a handshake then OpenSSL would move into the error state and would immediately fail if you attempted to continue the handshake. This works as designed for...

Improper access control

An improper access control vulnerability in Trend Micro Smart Protection Server Standalone versions 3.2 and below could allow an attacker to decrypt contents of a database with information that could be used to access a vulnerable system...

CVE-2017-14097

Trend Micro Smart Protection Server (Standalone)

OpenJDK: insufficient strength of key agreement (JCE, 8185292)

It was discovered that the key agreement implementations in the JCE component of OpenJDK did not guarantee sufficient strength of used keys to adequately protect generated shared secret. This could make it easier to break data encryption by attacking key agreement rather than the encryption using...

CVE-2017-17841

Palo Alto Networks PAN-OS 6.1, 7.1, and 8.0.x before 8.0.7, when an interface implements SSL decryption with RSA enabled or hosts a GlobalProtect portal or gateway, might allow remote attackers to decrypt TLS ciphertext data by leveraging a Bleichenbacher RSA padding oracle, aka a ROBOT attack...

CVE-2017-17841

CVE-2017-17841 affects PAN-OS 6.1, 7.1, and 8.0.x before 8.0.7 where SSL Decryption with RSA or a GlobalProtect portal/gateway can leak TLS plaintext via a Bleichenbacher padding oracle (ROBOT). PAN-OS mitigations include upgrading to PAN-OS 7.1.15 or 8.0.7 (and later), or applying workarounds su...
