Security Blueprints of Many Companies Leaked in Hack of Swedish Firm Gunnebo

October 28, 2020

In March 2020, KrebsOnSecurity alerted Swedish security giant Gunnebo Group that hackers had broken into its network and sold the access to a criminal group which specializes in deploying ransomware. In August, Gunnebo said it had successfully thwarted a ransomware attack, but this week it emerged that the intruders stole and published online tens of thousands of sensitive documents — including schematics of client bank vaults and surveillance systems.

The Gunnebo Group is a Swedish multinational company that provides physical security to a variety of clients globally, including banks, government agencies, airports, casinos, jewelry stores, tax agencies and even nuclear power plants. The company has operations in 25 countries, more than 4,000 employees, and billions in revenue annually.

Amid an Embarrassment of Riches, Ransom Gangs Increasingly Outsource Their Work

October 8, 2020

There’s an old adage in information security: “Every company gets penetration tested, whether or not they pay someone for the pleasure.” Many organizations that do hire professionals to test their network security posture unfortunately tend to focus on fixing vulnerabilities hackers could use to break in. But judging from the proliferation of help-wanted ads for offensive pentesters in the cybercrime underground, today’s attackers have exactly zero trouble gaining that initial intrusion: The real challenge seems to be hiring enough people to help everyone profit from the access already gained.

Ukraine Nabs Suspect in 773M Password ‘Megabreach’

In January 2019, dozens of media outlets raised the alarm about a new “megabreach” involving the release of some 773 million stolen usernames and passwords that was breathlessly labeled “the largest collection of stolen data in history.” A subsequent review by KrebsOnSecurity quickly determined the data was years old and merely a compilation of credentials pilfered from mostly public data breaches. Earlier today, authorities in Ukraine said they’d apprehended a suspect in the case.

Almost daily now there is news about flaws in commercial software that lead to computers getting hacked and seeded with malware.

How Cybercriminals are Weathering COVID-19

April 30, 2020

In many ways, the COVID-19 pandemic has been a boon to cybercriminals: With unprecedented numbers of people working from home and anxious for news about the virus outbreak, it’s hard to imagine a more target-rich environment for phishers, scammers and malware purveyors. In addition, many crooks are finding the outbreak has helped them better market their cybercriminal wares and services. But it’s not all good news: The Coronavirus also has driven up costs and disrupted key supply lines for many cybercriminals.

Federal investigators in Russia have charged at least 25 people accused of operating a sprawling international credit card theft ring.
