The security community witnessed triple-digit growth in the number of publicly disclosed ransomware incidents in 2020. As noted in a previous blog post on Five Things You Need to Know About Ransomware Attacks, ransomware attacks grew 715% in H1 2020 compared to the first half of the previous year. Ransomware incidents for 2020 overall increased by more than 150%. |

CNA, one of the largest U.S. commercial and casualty insurance companies, reportedly met a $40 million ransom demand after suffering a ransomware infection earlier in the year. As of this writing, that's the largest ransom demand ever reported to have been paid by a company following a ransomware attack. |

Late on Friday May 7, 2021, Colonial Pipeline, the company that runs the largest gasoline pipeline in the US, shut down operations following a ransomware attack on their systems. It later emerged that a relatively new ransomware-as-a-service criminal organization known as DarkSide was behind the attack - but there was a twist. |

2021-05-14 20:21:22 | Solving the Ransomware Crisis (lien direct) |
Ransomware attacks are trivial to execute and there is little, if any, risk and no penalties for the attackers. As a victim, there are no good choices once an organization is hit by ransomware. You can ignore the ransom demand and restore your data from backups and take your chances with the risk of data exposure. At the same time, the reality is that it doesn't pay to pay--it is not a guarantee that you will get all of the data back in a usable state.
In addition, when you pay the ransom you are essentially funding these criminals who are acting as terrorists. The chances are that you are funding additional research and development of the next exploit or ransomware variant, so paying the ransom just makes the problem bigger.
Organizations that pay the ransom also risk putting a bullseye on their backs-making themselves attractive targets for future ransomware attacks because they have established that they're willing to pay. The only good option is to avoid having your data stolen or encrypted in the first place, which is why it needs to be a global priority to solve this crisis. |

As we noted in a previous blog post, ransomware attacks are becoming more frequent and more costly. Reports reveal that there were 304 million ransomware attacks in 2020 - 62% more than the total number of ransomware attacks for 2019. The estimated cost of those incidents increased from $11.5 billion to $20 billion during that same time period. Average ransom costs also rose from $5,900 to $8,100 between those two years, with associated downtime losses growing from $141,000 to $283,000. |

Over the past year, we have seen many different types of ransomware attacks evolving, especially evolving into multistage ransomware that not only ransoms data, but also exfiltrates as much data as possible. Below is a brief overview of three of the most common modern ransomware attacks we are seeing today. |

Today, any random Google search for “ransomware attack” will result in a new story of an organization impacted by ransomware, and usually not for the first time. Ransomware attacks are an efficient and effective weapon for criminals who want to harm any business through crucial data loss, damaged productivity, and injured brand reputation. These attacks often have a big price tag attached to them, a combination of the business paying the ransom and the actual downtime the business suffers because of the attack. |

2020-06-11 04:15:00 | Cybereason\'s Newest Honeypot Shows How Multistage Ransomware Attacks Should Have Critical Infrastructure Providers on High Alert (lien direct) |
Introduction
Earlier this year, Cybereason launched its latest honeypot to analyze the tactics, techniques, and procedures used by state-sponsored groups and cyber crime actors to target critical infrastructure providers. This honeypot was a follow up to a previous successful honeypot launched two years ago in 2018 looking at the same industry. The honeypot was built to look like an electricity company with operations in North America and Europe.
In this new research, the Cybereason team identified multiple attackers executing ransomware operations involving data theft, the stealing of user credentials, and lateral movement across the victims network to compromise as many endpoints as possible. This includes critical assets like the domain controllers, which could take between several minutes to several hours to properly infiltrate.
Ransomware capabilities were deployed early on in the hacking operation, but it was not immediately detonated. The ransomware was designed to detonate only after preliminary stages of the attack finished across all compromised endpoints in order to achieve maximum impact on the victim.
This operational attack pattern attempts to impact as many victim assets as possible, representing a higher risk to organizations compared to ransomware attacks that impact the single machine they initially access. However, this operational pattern also represents an opportunity for defenders with a rapid detection and response process to detect the attack at its early stages and respond effectively before ransomware is able to impact the environment.
Given the results of this research, we conclude that multistage ransomware attacks on critical infrastructure providers are increasingly dangerous and more prevalent.
Check out a condensed, high level version of this report on our threat alerts page.
Background
We live in a world of insecurity where hackers have the advantage over the vast majority of enterprises trying to protect their computer networks. No where is that more evident than with critical infrastructure providers, who are facing a constant barrage of cyberattacks from motivated and oftentimes well-funded groups of cybercriminals and state-sponsored actors. |
