Vulnerabilities

Cybercrime

BitLocker, the disk encryption solution implemented in the Windows operating system starting with Windows Vista, does not require sophisticated tools or exploits to be bypassed on systems that do not have the latest patches from Microsoft installed, security researcher Ian Haken claims.

The hacker group Anonymous claimed Tuesday to have taken out 5,500 Twitter accounts linked to the Islamic State group, which claimed responsibility for the Paris attacks. The loosely organized hacking collective made the claim in a tweet one day after launching #OpParis campaign, which stepped up an earlier effort to shut down social media accounts of the organization.

Earlier this month, during the RSA Conference in Europe, Amit Yoran President of RSA and former cybersecurity director at the U.S. Department of Homeland Security proclaimed, “Infosec is fundamentally broken.”

Malicious actors have been targeting servers running vulnerable installations of the vBulletin forum software via a security hole patched by the developer earlier this month, Symantec warned on Monday.

Attacks designed to compromise users and steal sensitive data are increasing in magnitude and velocity as cybercriminals leverage automated tools, Imperva’s annual Web Application Attack Report (WAAR) reveals.

Britain on Tuesday said it will double its investment in cyber-security to counter threats including from the Islamic State group, in the wake of the Paris attacks claimed by IS.

Researchers discovered that the poor security practices of mobile app developers relying on Backend-as-a-Service (BaaS) offerings to make their job easier lead to the exposure of millions of records of potentially sensitive information.

The deadly Paris attacks have reignited debate on encrypted communications by terror cells and whether law enforcement and intelligence services are "going dark" in the face of new technologies.

It’s almost a cliche to talk about how often breaches occur—in 2015 alone, we’ve seen high-profile breaches from everyone from Anthem, the popular work collaboration tool Slack, and even the federal government thanks to the recent US Office of Personnel Management attack.

The Anonymous internet hacking network declared war on the Islamic State group in a Youtube video Monday, vowing vengeance for attacks in Paris that left 129 dead and hundreds injured. "Anonymous everywhere in the world is going to hunt you down," a hooded figure in black, wearing the group's signature Guy Fawkes mask said in French.
