Cloudflare DDoS Report Finds Increase in Attack Volume and Duration

/in


Cloudflare released its Distributed Denial of Service (DDoS) Threat Report for the fourth quarter of 2022. The report covers the DDoS attack landscape as detected by the Cloudflare network. HTTP DDoS attacks increased 79% year-over-year with ransom DDoS attacks seeing an increase as well. The report found that longer attacks on increasing especially with network-layer DDoS attacks.

Cloudflare found that attacks exceeding 100 gigabits per second increased by 67% quarter-over-quarter (QoQ). Attacks that lasted longer than three hours also increased by 87% QoQ. Omer Yoachimik, Product Manager at Cloudflare, notes that for HTTP DDoS attacks:

While most of these attacks were small, Cloudflare constantly saw terabit-strong attacks, DDoS attacks in the hundreds of millions of packets per second, and HTTP DDoS attacks peaking in the tens of millions of requests per second launched by sophisticated botnets.

In August of 2022, Google claimed that they fended off a DDoS attack that peaked at 46 million requests per second. Emil Kiner, Senior Product Manager at Google, and Satya Konduru, Engineering Lead at Google, put the scale of the attack into perspective:

To give a sense of the scale of the attack, that is like receiving all the daily requests to Wikipedia (one of the top 10 trafficked websites in the world) in just 10 seconds.

Yoachimik shares that Cloudflare defended an attack against a Korean-based hosting provider that reached one terabyte per second. The attack in question was an ACK flood and was about one minute in duration. An ACK flood attempts to overload a server with TCP ACK packets. The server consumes resources processing the ACK packages preventing it from handling legitimate requests.

Cloudflare found that HTTP DDoS attacks made up 35% of all traffic to Aviation and Aerospace Internet sites. For Education Management companies 92% of traffic was part of network-layer DDoS attacks. Yoachimik also shared that 93% of network-layer traffic to Chinese Internet properties was part of network-layer DDoS attacks.

Ransom DDoS attacks also increased with 16% of…

Decrease in malware volume, but surge in encrypted malware 

/in


There has been a reduction in overall malware detections from the peaks seen in the first half of 2021, an increase in threats for Chrome and Microsoft Office, the ongoing Emotet botnet resurgence, and much more, according to a new report. 

WatchGuard Technologies has announced findings from its most recent Internet Security Report, which details the top malware trends and network security threats analysed by WatchGuard Threat Lab researchers in Q2 2022. 

“While overall malware attacks in Q2 fell off from the all-time highs seen in previous quarters, over 81% of detections came via TLS encrypted connections, continuing a worrisome upward trend,” says Corey Nachreiner, Chief Security Officer at WatchGuard. 

“This could reflect threat actors shifting their tactics to rely on more elusive malware.”

The Q2 Internet Security Report found office exploits continue to spread more than any other category of malware.

In fact, the quarter’s top incident was the Follina Office exploit (CVE-2022-30190), which was first reported in April and not patched until late May. Delivered via a malicious document, Follina was able to circumvent Windows Protected View and Windows Defender and has been actively exploited by threat actors, including nation states. Three other Office exploits (CVE-2018-0802, RTF-ObfsObjDat.Gen, and CVE-2017-11882) were widely detected in Germany and Greece.

According the report, endpoint detections of malware were down overall, but not equally. 

Despite a 20% decrease in total endpoint malware detections, malware exploiting browsers collectively increased by 23%, with Chrome seeing a 50% surge. One potential reason for the increase in Chrome detections is the persistence of various zero day exploits. Scripts continued to account for the lions share of endpoint detections (87%) in Q2.

The top 10 signatures accounted for more than 75% of network attack detections, the report shows. This quarter saw increased targeting of ICS and SCADA systems that control industrial equipment and processes, including new signatures (WEB Directory Traversal -7 and WEB Directory Traversal -8). The two signatures are very similar; the first exploits a vulnerability first…

Report on Patient Privacy Volume 22, Number 2. Privacy Briefs: February 2022 | Health Care Compliance Association (HCCA)

/in


◆ Tensions between the U.S. and Russia could lead to a heightened risk of Russian state-sponsored cyberattacks on U.S. interests, including health care organizations, federal agencies warned. Russia would consider conducting a cyberattack on the U.S. homeland if Moscow perceived that a U.S. or NATO response to a potential Russian invasion of Ukraine threatened Russia’s long-term national security, according to a Department of Homeland Security intelligence bulletin obtained by CNN.[1] 1 The Cybersecurity & Infrastructure Security Agency (CISA), FBI and the National Security Agency have urged organizations to be prepared with cyber incident response, resilience, and continuity of operations plans so that critical functions and operations can be kept running if technology systems are disrupted or need to be taken offline. The three agencies also urged organizations to enhance their cyber posture by following best practices, and to increase organizational vigilance by staying current on threat reporting.[2] John Riggi, national advisor for cybersecurity and risk at the American Hospital Association, warned that hospitals and health systems could be targeted directly, or could become “incidental victims or collateral damage of Russian-deployed malware or destructive ransomware that inadvertently penetrates U.S. health care.” Riggi noted that “a cyberattack could disrupt a mission-critical service provider to hospitals,” and added that “this is a good reminder for all to have robust downtime procedures, redundancy and business continuity plans to sustain a loss of on-premises or cloud-based mission-critical services or technology for up to four to six weeks.”[3]

◆ CISA also advised U.S. critical infrastructure organizations to review a Microsoft blog on malware identified in Ukraine and take action to strengthen their networks against potential cyberattacks.[4] The Microsoft Threat Intelligence Center reported evidence of destructive malware in systems belonging to several Ukrainian government agencies and organizations that work closely with the Ukrainian government.[5] The malware is disguised as ransomware, but if activated by the attacker, it would render the…
