Security of iMessage System Comes to the Fore Again

The iMessage system, like much of what Apple does, is mostly a black box. The company doesn’t talk much about how the system works, and although some security researchers found a couple years ago that Apple could read users’ encrypted messages if they so choose, law enforcement has had no luck in...

Hardcoded credentials

Lockbox in EMC Documentum D2 before 4.5 uses a hardcoded passphrase when a server lacks a D2.Lockbox file, which makes it easier for remote authenticated users to decrypt admin tickets by locating this passphrase in a decompiled D2 JAR archive...

CVE-2015-4537

EMC Documentum D2 vulnerability CVE-2015-4537 affects the Lockbox component. If the server lacks the D2.Lockbox file, D2 uses a hardcoded passphrase to encrypt admin tickets, enabling an attacker who can decompile D2 JARs to recover the passphrase and decrypt tickets. Affected products include EM...

LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks

A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange for both export and non-export grade cipher suites. An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lea...

SSL/TLS: Padding Oracle On Downgraded Legacy Encryption attack

A flaw was found in the way SSL 3.0 handled padding bytes when decrypting messages encrypted using block ciphers in cipher block chaining CBC mode. This flaw allows a man-in-the-middle MITM attacker to decrypt a selected byte of a cipher text in as few as 256 tries if they are able to force a...
