Vulnerabilities

Cybercrime

Over the past few years, industrial control systems (ICS) components have proven to be increasingly vulnerable and more frequently accessible from the Internet, which significantly amplifies the risk they are exposed to, Kaspersky Lab researchers warn.

In what I like to call a cowardly Friday afternoon data breach disclosure, Omni Hotels disclosed that several of its hotel properties were impacted by malware infecting its point-of-sale (PoS) systems. 

DoS Vulnerability Affects Symantec Endpoint Protection (SEP) and Norton Products on WindowsSymantec has recently patched a denial of service (DoS) vulnerability that plagued its Norton Security’s Portable Executable file scanning functionality. 

EU member states on Friday approved a highly-criticized deal with the US intended to curb government spying on the personal internet data of EU citizens.

Kaspersky Lab is monitoring a new cyber espionage group that it calls Dropping Elephant. A surprising -- and somewhat worrying -- feature is that this group achieves a high success rate with only low tech attacks. In fact, it has been so successful that it seems to have expanded it group membership from (probably) just India to include new members on the Pacific West Coast of America.

Facebook announced Friday it would roll out optional "end to end encryption" for its Messenger application, following a trend aimed at stronger security and protection against snooping.

Fast food restaurant chain Wendy’s revealed on Thursday that the number of restaurants believed to have been compromised with point-of-sale (PoS) malware is now over 1,000--a figure three times larger than the initial number announced by the company in May.

Which Republican is most likely to impede Hillary Clinton's race to the White House? Most would say Donald Trump, but FBI director James Comey could be the surprise obstacle on her path to 1600 Pennsylvania Avenue.
